    Full Text Available Abstract Background We hypothesize that the integration of virtual reality (VR with robot assisted rehabilitation could be successful if applied to children with hemiparetic CP. The combined benefits of increased attention provided by VR and the larger training stimulus afforded by adaptive robotics may increase the beneficial effects of these two approaches synergistically. This paper will describe the NJIT-RAVR system, which combines adaptive robotics with complex VR simulations for the rehabilitation of upper extremity impairments and function in children with CP and examine the feasibility of this system in the context of a two subject training study. Methods The NJIT-RAVR system consists of the Haptic Master, a 6 degrees of freedom, admittance controlled robot and a suite of rehabilitation simulations that provide adaptive algorithms for the Haptic Master, allowing the user to interact with rich virtual environments. Two children, a ten year old boy and a seven year old girl, both with spastic hemiplegia secondary to Cerebral Palsy were recruited from the outpatient center of a comprehensive pediatric rehabilitation facility. Subjects performed a battery of clinical testing and kinematic measurements of reaching collected by the NJIT-RAVR system. Subjects trained with the NJIT-RAVR System for one hour, 3 days a week for three weeks. The subjects played a combination of four or five simulations depending on their therapeutic goals, tolerances and preferences. Games were modified to increase difficulty in order to challenge the subjects as their performance improved. The testing battery was repeated following the training period. Results Both participants completed 9 hours of training in 3 weeks. No untoward events occurred and no adverse responses to treatment or complaints of cyber sickness were reported. One participant showed improvements in overall performance on the functional aspects of the testing battery. The second subject made

  5. Physicists get INSPIREd

    CERN Multimedia

    CERN Bulletin

    2010-01-01

    Particle physicists thrive on information. They first create information by performing experiments or elaborating theoretical conjectures and then they share it through publications and various web tools. The INSPIRE service, just released, will bring state of the art information retrieval to the fingertips of researchers.   Keeping track of the information shared within the particle physics community has long been the task of libraries at the larger labs, such as CERN, DESY, Fermilab and SLAC, as well as the focus of indispensible services like arXiv and those of the Particle Data Group. In 2007, many providers of information in the field came together for a summit at SLAC to see how physics information resources could be enhanced, and the INSPIRE project emerged from that meeting. The vision behind INSPIRE was built by a survey launched by the four labs to evaluate the real needs of the community. INSPIRE responds to these directives from the community by combining the most successful aspe...

  6. Summertime for physicists

    CERN Multimedia

    2013-01-01

    Summer for particle physicists is the season for “summer conferences” and the past week saw two big meetings in full swing. The 2013 European Physical Society High-Energy Physics (EPS-HEP) conference took place in Stockholm, Sweden, while the Strangeness in Quark Matter conference visited Birmingham in the UK for its 2013 edition.   Such conferences usually mark the culmination of months of hard work to prepare new results and, if nature is kind, they also provide the stage for the announcement of discoveries. But more than that, they allow people to network with colleagues from far and wide. I was at EPS-HEP, which belies its name and, like particle physics itself, has a global reach, with people attending from Asia and the Americas. This year there were some 750 attendees, including many young people. The programme of parallel sessions allowed many of them to present results they had worked on in what can be huge collaborations. It’s impressive to see their eff...

    On 29 June the CERN theorist Gabriele Veneziano was awarded the prestigious Albert Einstein Medal for significant contributions to the understanding of string theory. This award is given by the Albert Einstein Society in Bern to individuals whose scientific contributions relate to the work of Einstein. Former recipients include exceptional physicists such as Murray Gell-Mann last year, but also Stephen Hawking and Victor Weisskopf. Gabriele Veneziano, a member of the integrated CERN Theory Team since 1977, led the Theory Division from 1994 to 1997 and has already received many prestigious prizes for his outstanding work, including the Enrico Fermi Prize (see CERN Courier, November 2005), the Dannie Heineman Prize for mathematical physics of the American Physical Society in 2004 (see Bulletin No. 47/2003), and the I. Ya. Pomeranchuk Prize of the Institute of Theoretical and Experimental Physics (Moscow) in 1999.

  8. Nuclear Physicists in Finance

    2017-01-01

    The financial services industry presents an interesting alternative career path for nuclear physicists. Careers in finance typically offer intellectual challenge, a fast pace, high caliber colleagues, merit-based compensation with substantial upside, and an opportunity to deploy skills learned as a physicist. Physicists are employed at a wide range of financial institutions on both the ``buy side'' (hedge fund managers, private equity managers, mutual fund managers, etc.) and the ``sell side'' (investment banks and brokerages). Historically, physicists in finance were primarily ``quants'' tasked with applying stochastic calculus to determine the price of financial derivatives. With the maturation of the field of derivative pricing, physicists in finance today find work in a variety of roles ranging from quantification and management of risk to investment analysis to development of sophisticated software used to price, trade, and risk manage securities. Only a small subset of today's finance careers for physicists require the use of advanced math and practically none provide an opportunity to tinker with an apparatus, yet most nevertheless draw on important skills honed during the training of a nuclear physicist. Intellectually rigorous critical thinking, sophisticated problem solving, an attention to minute detail and an ability to create and test hypotheses based on incomplete information are key to both disciplines.

    More than 1350 women physicists from more than 70 countries responded to a survey designed to identify issues important to women in physics. Women physicists had many areas of concern, notably discrimination and career/family balance. However, they also had many successes in physics. The majority would choose physics again and felt that they had progressed in their careers at least as quickly as their colleagues. Many spoke eloquently about their love of physics, the support they had received from others, and about their own determination and hard work.

    CERN physicists don't wear white coats (at least not very often); they don't all wear glasses and they don't concoct dangerous potions. They are often even women. These are some of the discoveries made by children from local schools taking part in the "Draw me a physicist" project. Franck Martin, an ATLAS physicist, answers questions from children from the Satigny-Village school.   20 school-classes from the Swiss communes of Meyrin, Satigny and Vernier and from the Pays de Gex in France have been taking part in this project, which involved the children making an initial drawing and writing a "dictionary-style" definition of a physicist in their classrooms, and then visiting CERN during the week of March 15th. The Swiss children were also treated to a show put on by the Physicscope group. During their visit to CERN they were able to see the laboratories and experiments for real and get an idea of what a physicist's job involves by interviewing a real male and...

    Mathematics for Physicists is a relatively short volume covering all the essential mathematics needed for a typical first degree in physics, from a starting point that is compatible with modern school mathematics syllabuses. Early chapters deliberately overlap with senior school mathematics, to a degree that will depend on the background of the individual reader, who may quickly skip over those topics with which he or she is already familiar. The rest of the book covers the mathematics that is usually compulsory for all students in their first two years of a typical university physics degree, plus a little more. There are worked examples throughout the text, and chapter-end problem sets. Mathematics for Physicists features: * Interfaces with modern school mathematics syllabuses * All topics usually taught in the first two years of a physics degree * Worked examples throughout * Problems in every chapter, with answers to selected questions at the end of the book and full solutions on a website This text will ...

  17. Euler as Physicist

    Suisky, Dieter

    2008-01-01

    "Euler as Physicist" analyzes the exceptional role of Leonhard Euler (1707 - 1783) in the history of science and emphasizes especially his fundamental contributions to physics. Although Euler is famous as the leading mathematician of the 18th century, his contributions to physics are as important for their innovative methods and solutions. Several books are devoted to Euler as mathematician, but none to Euler as physicist, like in this book. Euler’s contributions to mechanics are rooted in his life-long plan presented in two volume treatise programmatically entitled "Mechanics or the science of motion analytically demonstrated". Published in 1736, Euler’s treatise indicates the turn over from the traditional geometric representation of mechanics to a new approach. In writing Mechanics Euler did the first step to put the plan and his completion into practice through 1760. It is of particular interest to study how Euler made immediate use of his mathematics for mechanics and coordinated his progress in math...

    Startups and large corporations are full of physicists, many hiding in plain sight. Why? I will discuss the strong parallels between basic research in nuclear/particle physics, founding teams at great startups, and leaders at some of the world's largest corporations. How big are these opportunities (mission and capital), and what can we do to help prepare more physicists for such roles? I will provide lessons learned from my winding career that began at the NSCL as a philosophy undergrad, proceeded through a PhD, postdoc and brief stint as faculty, and continued through the founding of an early cloud computing startup, a sale to IBM, and the founding of one of Silicon Valley's most active venture capital firms.

  20. Physicist or computer specialist?

    Energy Technology Data Exchange (ETDEWEB)

    Clifton, J S [University College Hospital, London (United Kingdom)

    1966-06-15

    Since to most clinicians physical and computer science are two of the great mysteries of the world, the physicist in a hospital is expected by clinicians to be fully conversant with, and competent to make profound pronouncements on, all methods of computing. specific computing problems, and the suitability of computing machinery ranging from desk calculators to Atlas. This is not surprising since the proportion of the syllabus devoted to physics and mathematics in an M. B. degree is indeed meagre, and the word 'computer' has been surrounded with an aura of mysticism which suggests that it is some fantastic piece of electronic gadgetry comprehensible only to a veritable genius. The clinician consequently turns to the only scientific colleague with whom he has direct contact - the medical physicist - and expects him to be an authority. The physicist is thus thrust, however unwillingly, into the forefront of the advance of computer assistance to scientific medicine. It is therefore essential for him to acquire sufficient knowledge of computing science to enable him to provide satisfactory answers for the clinicianst queries, to proffer more detailed advice as to programming convince clinicians that the computer is really a 'simpleton' which can only add and subtract and even that only under instruction.

  1. The last universal physicist

    Born in Rome in 1901, Fermi was the last universal physicist - the most extraordinary of his century. He was at home in the workshop, the laboratory and among theoretical physicists. For the theorists he was a great theorist, and for the experimentalists he was a great experimentalist. What made Fermi so special as a physicist was his universality and versatility; what made him so special as a person was his modesty, realism and frugal lifestyle. This book, which describes Fermi's contributions to physics and the US period of his life, originated from a symposium that was held in Chicago in 2001 to commemorate the centenary of his birth. But it is not merely a volume of reminiscences. It combines essays, specially commissioned articles, as well as private material from Fermi's research notebooks, correspondence and speeches. Together the material highlights the breadth of his impact on physics. A classic biographical introduction by Emilio Segre is followed by an article in which Frank Wilczek, who shared the Nobel Prize for Physics last year, puts into perspective Fermi's huge contributions to physics. The list of his achievements is impressive. They include the introduction of Fermi statistics for half-integer-spin particles (1925) - now called fermions - that led to the concept of the 'Fermi surface' in condensed-matter and nuclear physics; the vector-coupling theory for beta-decay (1933), which formulated the proper structure of the weak interaction where the 'Fermi constant' measures the strength of the coupling; and the introduction, with his Rome group, of neutron-induced radioactivity and the study of slow-neutron interactions (1934). As a researcher and a teacher, Fermi inspired two generations and two continents - a man whose charismatic nature attracted many talented scientists and students to Chicago. What emerges from this book is the gratitude of so many extraordinary physicists to their master, who instilled in them

  2. Female physicist doctoral experiences

    Full Text Available The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

    The modern radiotherapy requires a medical physicist who optimizes treatment plans, assures delivered dose equal to prescription, and performs QA (quality assurance) of radiotherapy equipments. However, medical physicist has not been established as a medical profession in Japan mainly because importance of radiotherapy was not sufficiently recognized until recently. Between 2000 and 2004, several accidents of radiotherapy including hundreds of patients were found and these accidents were mainly caused by lack of QA. The necessity and importance of medical physicist were recognized by these accidents as well as by the advent of high-precision radiotherapy such as IMRT (intensity modulation radiation therapy). JRS (Japan Radiological Society) that certified medical physicists with the help of JSMP (Japan Society of Medical Physics), decided to extend eligibility in order to increase certified medical physicists rapidly in 2003. After the decision certified medical physicists were rapidly increased in number. The government supports this tendency to enact that certified medical physicists is necessary to reimbursement for high-precision therapy. It also started to supply grants for medical physics training in physical and health science graduate schools. In this program several universities have started medical physics course in their graduate schools. If these movements continue, medical physicist will be established as a medical profession in the near future. (author)

In fact, for the past two days, results had been shown from both experiments as well as from the Tevatron experiments in various individual channels. But today, the latest combined results from each experiment were shown in public for the first time. Of course, all physicists belonging either to the CMS or ATLAS experiment had had a chance t...

  14. The health physicist abroad

    Stewart, N.G.

    1980-01-01

    As health physics research teams at Harwell found adequate solutions to some of the problems in radiological protection and other spheres of nuclear technology, a mixed research programme consisting of both nuclear and non-nuclear research was undertaken by the health physics research teams since 1968 at Harwell with the aim of retaining radiological research experience. This policy widened the scope and interests of the health physicists and subsequently it was observed that particularly in the field of environment and toxicology, the division between nuclear and non-nuclear research is an artificial one. For example, the techniques developed and skills acquired to study the uptake and metabolism of radioactive aerosols were employed to study inhalation toxicology of lead aerosols from motor vehicles and their deposition on the plant and soil surfaces, influence of particle size on deposition and uptake of lead by man and plants. These techniques and skills were redeployed on new radiological problems as they arose, for example, to study the deposition and resuspension of plutonium from land and water surfaces to provide data appropriate to European conditions. Some such more examples from the work of the Environmental and Medical Sciences Division at Harwell are given. (M.G.B.)

  20. Perspective for Female Medical Physicists

    International Nuclear Information System (INIS)

    2009-01-01

    Due to cultural and religious reasons, Pakistani women can be reluctant to seek medical attention for disorders affecting their genitals or breasts. As a result, in the case of cervical and breast cancers, oncological treatment is often not received until the diseases are in the late stages. Once a cancer is classified and the tumor marked, the role of the medical physicist begins. Medical physicists' responsibilities include treatment planning, supervising treatment through radiation, dosimetry, contouring, training, equipment selection, education, research, and supervising radiotherapy facilities. In brachytherapy, isotopes are placed at the tumor site in the form of wires or seeds. There are very few female medical physicists in Pakistan. This leads to further hesitation on the part of many women to seek treatment. To help female patients obtain needed medical care, female physics students should be encouraged to pursue the emerging field of medical physics. This would provide a new professional opportunity for female physics students and give comfort to female patients.

  4. LHC Olympics flex physicists' brains

    CERN Multimedia

    2006-01-01

    Physicists from around the world met at CERN to strengthen their data-deciphering skills at the second LHC Olympics workshop. Physicists gather for the second LHC Olympics workshop. Coinciding with the kick-off of the winter Olympics in Turin, more than 70 physicists gathered at CERN from across the globe for the second LHC Olympics workshop on 9-10 February. Their challenge, however, involved brains rather than brawn. As the switch-on date for the LHC draws near, scientists excited by the project want to test and improve their ability to decipher the unprecedented amount of data that the world's biggest and most powerful particle accelerator is expected to generate. The LHC Olympics is a coordinated effort to do just that, minus the gold, silver and bronze of the athletics competition. 'In some ways, the LHC is not a precision instrument. It gives you the information that something is there but it's hard to untangle and interpret what it is,' said University of Michigan physicist Gordy Kane, who organiz...

  7. Physicists' Forced Migrations under Hitler

    Beyerchen, Alan

    2011-03-01

    When the Nazis came to power in early 1933 they initiated formal and informal measures that forced Jews and political opponents from public institutions such as universities. Some physicists retired and others went into industry, but most emigrated. International communication and contact made emigration a viable option despite the desperate economic times in the Great Depression. Another wave of emigrations followed the annexation of Austria in 1938. Individual cases as well as general patterns of migration and adaptation to new environments will be examined in this presentation. One important result of the forced migrations was that many of the physicists expelled under Hitler played important roles in strengthening physics elsewhere, often on the Allied side in World War II.

    With the advent of CT and MR imaging, delineation of malignancies and the shaping of radiation treatment fields have become much more precise. Treatment planning in more than one transverse plane is more widely practiced as the use of sophisticated computers grow. These developments emphasize the need for the physicist to have a basic knowledge of human anatomy. This course is designed to familiarize the clinical physicist with the gross anatomy and topographic landmarks used by the physician in planning three-dimensional radiation treatment volumes. The significance of the various anatomic structures and their related lymphatics in the spread of disease is discussed. Emphasis is placed on disease entities that pose particular problems due to overlying or nearby healthy structures at risk

    This Monitored Drift Tube detector, consisting of argon-CO2-filled aluminium tubes with a wire down the centre of each, will track muons in ATLAS; Tiecke used a single tube from one of these detectors to create the pipes in his organ. Particle physicists can make good musicians; but did you know particle detectors can make good music? That's what NIKHEF physicist Henk Tiecke learned when he used pipes cut from the ATLAS Monitored Drift Tube detector (MDT) to build his own working Dutch-style barrel organ in the autumn of 2005. 'I like to work with my hands,' said Tiecke, who worked as a senior physicist at NIKHEF, Amsterdam, on ZEUS until his retirement last summer. Tiecke had already constructed his barrel organ when he visited some colleagues in the ATLAS muon chambers production area at Nikhef in 2005. He noticed that the aluminium tubes they were using to build the chambers were about three centimetres in diameter-just the right size for a pipe in a barrel organ.

    The murder of the Iranian physicist Masoud Alimohammadi last month has left the country's academic community in a state of shock. Alimohammadi, a 50-year-old physics professor at the University of Tehran, was killed on 12 January by a remote-controlled bomb attached to the side of a motorcycle outside his home. The bomb was detonated as he left for work, but the reason for the murder remained unclear as Physics World went to press. Reports by the Iranian state media blamed the US and Israel for the attack - a claim that the US later described as "absurd".

  13. An Applied Physicist Does Econometrics

    Science.gov (United States)

    Taff, L. G.

    2010-02-01

    The biggest problem those attempting to understand econometric data, via modeling, have is that economics has no F = ma. Without a theoretical underpinning, econometricians have no way to build a good model to fit observations to. Physicists do, and when F = ma failed, we knew it. Still desiring to comprehend econometric data, applied economists turn to mis-applying probability theory---especially with regard to the assumptions concerning random errors---and choosing extremely simplistic analytical formulations of inter-relationships. This introduces model bias to an unknown degree. An applied physicist, used to having to match observations to a numerical or analytical model with a firm theoretical basis, modify the model, re-perform the analysis, and then know why, and when, to delete ``outliers'', is at a considerable advantage when quantitatively analyzing econometric data. I treat two cases. One is to determine the household density distribution of total assets, annual income, age, level of education, race, and marital status. Each of these ``independent'' variables is highly correlated with every other but only current annual income and level of education follow a linear relationship. The other is to discover the functional dependence of total assets on the distribution of assets: total assets has an amazingly tight power law dependence on a quadratic function of portfolio composition.

  18. Marie Curie: Physicist and Woman

    Science.gov (United States)

    Howes, Ruth

    Marie Sklodowska was born in Warsaw on November 7, 1867. Girls were not allowed to attend college in Poland, so Marie found a well-paying post as a governess in rural village which she held for three years while helping her older sister complete medical school in Paris. Then Marie moved to Paris and graduated first in her class at the Sorbonne with a master's degree in physics in 1893. In 1895, she married the talented young physicist, Pierre Curie. Marie decided to investigate the radioactive components of the mineral pitchblende for her dissertation. The work involved chemical analysis of a ton of material in an unheated shed. Pierre joined her and at the end of 1898, the Curies announced the discovery of radium and polonium. Through 1899, Marie labored to measure the atomic weight of radium. In 1903, Marie earned her doctorate, the first for a woman in France, and the Curies split the Nobel Prize in Physics with Henri Becquerel. They became widely known, besieged by the press and frequently invited to make presentations and be awarded honors. They hated fame and both suffered bad health. In April, 1906, Pierre Curie was struck by a wagon and killed instantly. Marie was left as a single mother with two young daughters. Fortunately, the Sorbonne hired her to fill Pierre's position. In 1911, she was rejected for membership in the French Academy of Science because she was a woman. Also in 1911, she was accused of having an affair with a married French physicist Paul Langevin. The resulting scandal hit the press and brought angry mobs to her home. In the middle of this hullaballoo, she was informed that she had won a second Nobel Prize, this time in Chemistry. When World War I broke out, Marie mounted x-ray units on cars and became a heroine. She visited the United States in 1921 where President Harding presented her with a gram of radium. She continued her scientific studies in spite of declining health until her death in 1934. Professor Emerita.

  19. Physicists and Economic Growth: Preparing the Next Generation

    Science.gov (United States)

    Arion, Douglas

    2012-02-01

    For many years it has been recognized that many physicists are ``hidden'' -- deep in the industrial world or holding positions not named ``physicist.'' In parallel with this phenomenon is the recognition that many new and innovative product ideas are, in fact, generated by physicists. There are many more ideas that could be brought to market to the benefit of both society and the inventor, but physicists don't often see themselves as the innovators and inventors that they actually are. A number of education programs have arisen to try to address this issue and to engender a greater entrepreneurial spirit in the scientific community. The ScienceWorks program at Carthage College was one of the first to do so, and has for nearly twenty years prepared undergraduate science majors to understand and practice innovation and value creation. Other programs, such as professional masters degrees, also serve to bridge the technical and business universes. As it is no doubt easier to teach a scientist the world of business than it is to teach a businessperson the world of physics, providing educational experiences in innovation and commercialization to physics students can have tremendous economic impact, and will also better prepare them for whatever career direction they may ultimately pursue, even if it is the traditional tenure-track university position. This talk will discuss education programs that have been effective at preparing physics students for the professional work environment, and some of the positive outcomes that have resulted. Also discussed will be the variety of opportunities and resources that exist for faculty and students to develop the skills, knowledge and abilities to recognize and successfully commercialize innovations.

Numerous textbooks are available covering the various subspecialties of medical physics but they generally make a transition from the elementary basic physics directly into the intricacies of the given medical physics subspecialty. The intent of this textbook is to provide the missing link between the elementary physics on the one hand and the physics of the subspecialties on the other hand. (orig.)

    There are many physicists working in the industrial sector. We rarely have the word physicist in our job title; we are far more commonly called engineers or scientists. But, we are physicists, and we succeed because our training in physics has given us the habits of mind and the technical skills that one needs to solve complex technical challenges. This talk will explore the transition from physics research to technology product development using examples from my own career, first as a postdoctoral fellow and research scientist on the LIGO project, and then developing products in the spectroscopy, telecommunications, and medical device industries. Approaches to identifying and pursuing opportunities in industry will be discussed.

    2004-09-01

    Here is a lively history of modern physics, as seen through the lives of thirty men and women from the pantheon of physics. William H. Cropper vividly portrays the life and accomplishments of such giants as Galileo and Isaac Newton, Marie Curie and Ernest Rutherford, Albert Einstein and Niels Bohr, right up to contemporary figures such as Richard Feynman, Murray Gell-Mann, and Stephen Hawking. We meet scientists--all geniuses--who could be gregarious, aloof, unpretentious, friendly, dogged, imperious, generous to colleagues or contentious rivals. As Cropper captures their personalities, he also offers vivid portraits of their great moments of discovery, their bitter feuds, their relations with family and friends, their religious beliefs and education. In addition, Cropper has grouped these biographies by discipline--mechanics, thermodynamics, particle physics, and others--each section beginning with a historical overview. Thus in the section on quantum mechanics, readers can see how the work of Max Planck influenced Niels Bohr, and how Bohr in turn influenced Werner Heisenberg. Our understanding of the physical world has increased dramatically in the last four centuries. With Great Physicists , readers can retrace the footsteps of the men and women who led the way.

    2012-01-01

    The actions taken during the first years of the Radiation to Electronics (R2E) Mitigation Project has allowed a drastic reduction of the rate of Single Event Errors (SEEs) on radiation-sensitive electronic equipment installed in the LHC underground areas. Shielding and relocation activities, performed during the first Long Shutdown (LS1) in 2013/2014, will allow the resolution of the present issues concerning UJs of Points 1, 5, 7 and the cavern of Point 8. The parallel development of radiation tolerant power converters will address the remaining concerns for equipment in the RRs. Similarly research works on super-conducting links will address the relocation of equipment away from RRs and further exposed UJs. Radiation levels in areas where luminosity is the source are under control. The questions yet remaining are related to the evolution of the beam-gas source term in the arc and dispersion suppressor region, and to the evolution of losses at the betatron and momentum insertion regions. 2012 operation will enable these points to be investigated; this will be used for a complete forecast of radiation levels and projected failures after operation is resumed in 2014-15.

    Matthews, Michael R.

    Mario Bunge was born in Argentina in the final year of the First World War.He learnt atomic physics and quantum mechanics from an Austrian refugee who had been a student of Heisenberg. Additionally he taught himself modern philosophy in an environment that was a philosophical backwater. He was the first South American philosopher of science to be trained in science. His publications in physics, philosophy, psychology, sociology and the foundations of biology, are staggering in number, and include a massive 8-volume Treatise on Philosophy. The unifying thread of his scholarship is the constant and vigorous advancement of the Enlightenment Project, and criticism of cultural and academic movements that deny or devalue the core planks of the project: namely its naturalism, the search for truth, the universality of science, rationality, and respect for individuals. At a time when specialisation is widely decried, and its deleterious effects on science, philosophy of science, educational research and science teaching are recognised - it is salutary to see the fruits of one person's pursuit of the Big'' scientific and philosophical picture.

  8. Hubbert's Peak -- A Physicist's View

    Science.gov (United States)

    McDonald, Richard

    2011-04-01

    Oil, as used in agriculture and transportation, is the lifeblood of modern society. It is finite in quantity and will someday be exhausted. In 1956, Hubbert proposed a theory of resource production and applied it successfully to predict peak U.S. oil production in 1970. Bartlett extended this work in publications and lectures on the finite nature of oil and its production peak and depletion. Both Hubbert and Bartlett place peak world oil production at a similar time, essentially now. Central to these analyses are estimates of total ``oil in place'' obtained from engineering studies of oil reservoirs as this quantity determines the area under the Hubbert's Peak. Knowing the production history and the total oil in place allows us to make estimates of reserves, and therefore future oil availability. We will then examine reserves data for various countries, in particular OPEC countries, and see if these data tell us anything about the future availability of oil. Finally, we will comment on synthetic oil and the possibility of carbon-neutral synthetic oil for a sustainable future.

    2012-02-01

    In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

    Simulation of particle tracks in the CMS detector. How can you 'see' something as infinitesimal and fleeting as an elementary particle that defeats even the most powerful microscope? Well, physicists have detectors to snoop on them. Unlike biologists looking at bacteria, physicists don't see the particles themselves. They study their impact on sensitive materials as they pass through them at ultra high speed, a bit like seeing plane vapour trails in a clear sky. At the next Discovery Monday you will be able to find out about the different methods used at CERN to detect particles. There will be demonstrations of the cloud chamber, where particles leave tell-tale evidence of their passage in tracks of droplets. You will also learn about past and current particle track detection techniques and how the tracks are reconstructed into magnificent composite images. Don't miss this opportunity to learn about the various ways of 'seeing' particles. The event will be conducted in French. Come along to the Microcosm ...

  18. Directory and survey of particle physicists

    International Nuclear Information System (INIS)

    1997-04-01

    In order to develop a clearer understanding of the demographics of the U.S. particle physics workforce, the US Department of Energy, the National Science Foundation, and the Division of Particles and Fields of the American Physical Society commissioned a survey and census of particle physicists employed in the United States. This survey and census were conducted in 1995, with an update of the census in April 1997. The agencies and the scientific community were represented for the 1995 efforts by Dr. Robert Woods (DOE), Dr. William Chinowsky (NSF), and Prof. Uriel Nauenberg (DPF); for the current census, by Dr. Robert Diebold (DOE), Dr. Marvin Goldberg (NSF), and Dr. Patricia Rankin (NSF). The survey/census were carried out with the assistance of the Particle Data Group at Lawrence Berkeley National Laboratory. In order to obtain an accurate study of the current workforce and of future needs, we requested that all HEP physicists fill out and return the 1995 survey. There were 2494 respondents. For the 1997 census, a representative of each university and laboratory was asked to provide information on all persons at that institution who spend at least 50% of their research time on particle physics. In some cases this includes accelerator physicists. The total number of physicists in the 1997 census is 3492 from 155 institutions in the United States. The full survey questionnaires are shown. The primary one was addressed to individual particle physicists, while the secondary one was addressed to principal investigators and sought information about people leaving the field. There are many possible tables and plots from this survey, with a variety of correlations. Those chosen are representative of a cross-section of the demographic results. It should be emphasized that this survey was a snapshot in time, and does not have the same capabilities as would a series of surveys that are periodic in time. Care should be taken in interpreting the results of the tables and plots

    2000-01-01

    Four CERN physicists, Peggie Rimmer, Ugo Amaldi, Alain Blondel, and Jean-Marie Le Goff, answered questions from 150 college students last Monday during a debate on the theme of the ethics of physics. Organized by CERN and the Department of public instruction of the Canton of Geneva, the meeting followed a reading by the students of the play Die Physiker, by Friedrich Dürrenmatt, which raises the problem of political exploitation of discoveries made during the second world war. The Minister of Education of the Canton de Genève, Mrs Martine Brunschwig-Graf, took part in the debate. The questions posed by students were not lacking in pertinence : Should a physicist reveal a discovery that is dangerous in his opinion ? Who are responsible, those who make the discoveries or those who use them ?

  5. Radiation oncology a physicist's-eye view

    2007-01-01

    Radiation Oncology: A Physicist's-Eye View was written for both physicists and medical oncologists with the aim of helping them approach the use of radiation in the treatment of cancer with understanding, confidence, and imagination. The book will let practitioners in one field understand the problems of, and find solutions for, practitioners in the other. It will help them to know "why" certain approaches are fruitful while, at the same time, encouraging them to ask the question "Why not?" in the face of assertions that some proposal of theirs is impractical, unreasonable, or impossible. Unlike a textbook, formal and complete developments of the topics are not among the goals. Instead, the reader will develop a foundation for understanding what the author has found to be matters of importance in radiation oncology during over thirty years of experience. Presentations cover, in largely non-technical language, the principal physical and biological aspects of radiation treatment and address practical clinical c...

    We present the development of the ``Future Physicists of Florida'' (FPF) comprised of Florida university physics professors, middle and high school science teachers, and backed by the Florida Legislature. Our purpose is to address the lack of incoming college freshmen ready and willing to become physics majors. We will discuss the building of FPF and the development of a pipeline for middle and high school students predicted to produce the optimal number of bachelor's degrees in STEM. We will also discuss our use of community-building activities to educate the students, and their parents and teachers about the educational value of taking physics before going to college and potential careers in physics, to entertain them with fun physics related activities in order to peak their interest in physics, and to ultimately inspire the students to become physicists.

  8. Feedback between Accelerator Physicists and magnet builders

    International Nuclear Information System (INIS)

    Peggs, S.

    1995-01-01

    Our task is not to record history but to change it. (K. Marx (paraphrased)) How should Accelerator Physicists set magnet error specifications? In a crude social model, they place tolerance limits on undesirable nonlinearities and errors (higher order harmonics, component alignments, etc.). The Magnet Division then goes away for a suitably lengthy period of time, and comes back with a working magnet prototype that is reproduced in industry. A better solution is to set no specifications. Accelerator Physicists begin by evaluating expected values of harmonics, generated by the Magnet Division, before and during prototype construction. Damaging harmonics are traded off against innocuous harmonics as the prototype design evolves, lagging one generation behind the evolution of expected harmonics. Finally, the real harmonics are quickly evaluated during early industrial production, allowing a final round of performance trade-offs, using contingency scenarios prepared earlier. This solution assumes a close relationship and rapid feedback between the Accelerator Physicists and the magnet builders. What follows is one perspective of the way that rapid feedback was used to 'change history' (improve linear and dynamic aperture) at RHIC, to great benefit

    2012-10-01

    The majority of pre- and post-graduate training in physics is focused on the acquisition of hard skills necessary to pursue academic research within a specific discipline of the broader field. Often many physics graduates view a career transition from academia to the private sector with much consternation. In this presentation, Moe Kermani will share his experience in making the transition and discuss how elements of post graduate training in physics provide a good foundation for success as an entrepreneur. This presentation is primarily aimed at young physicists and graduate students that are considering a transition from the academic sector to the world of technology startups.

  13. Physicists make the most of antimatter

    International Nuclear Information System (INIS)

    Kalmus, Peter

    1987-01-01

    The paper concerns the detection and creation of antimatter. The concept of antimatter was first suggested by Schuster in 1898, was predicted by Dirac in the 1930's and discovered in an accelerator experiment in California in the 1950's. So far, physicists have found no evidence of large amounts of antimatter in nature. However, the creation of artificial antimatter in the laboratory is a possibility. The facilities at CERN should enable the making of antimatter, by using the antiproton beam from LEAR, to make antihydrogen. (UK)

  15. What physicists should know about finance

    Science.gov (United States)

    Schmidt, Anatoly B.

    2005-05-01

    There has been growing interest in Econophysics, i.e. analysis and modeling of financial time series using the theoretical Physics concepts (scaling, fractals, chaos). Besides the scientific stimuli, this interest is backed by perception that the financial industry is a viable alternative for those physicists who are not able or are not willing to pursue an academic career. However, the times when any Ph.D. in Physics had a chance to find a job on the Wall Street are gone (if they ever existed). Indeed, not every physicist wields the stochastic calculus, non-normal statistical distributions, and the methods of time series analysis. Moreover, now that many universities offer courses in mathematical finance, the applicants for quantitative positions in finance are expected to know such concepts as option pricing, portfolio management, and risk measurement. Here I describe a synthetic course based on my book [1] that outlines both worlds: Econophysics and Mathematical Finance. The course may be offered as elective for senior undergraduate or graduate Physics majors.

  17. Paths to Licensure: Things Physicists Should Know

    Science.gov (United States)

    Stewart, Gay; Stewart, John

    2016-03-01

    The path to licensure can be quite complicated, and can thwart a physics department's efforts to produce more and better prepared high school physics teachers. Each state has different pathways to licensure. Acronyms like CAEP and SPA are not within the normal physicist's vocabulary. Some understanding of this topic can allow physics faculty advisers to help our students so that fewer are derailed on their path to the classroom, or take a path that will leave them less well prepared if they do find themselves there. Examples of different approaches that work within state licensure systems from two different states will be presented. Physics teacher preparation efforts in both Arkansas and West Virginia have been supported in part by the Physics Teacher Education Coalition (PhysTEC).

    The ideal workplace is one in which women and men can work to their potential and are respected and recognized for their contribution. But what are the conditions that would create this environment, and how can we achieve this? This paper highlights some of the best practices, discussed in a single-session workshop, to improve the workplace environment for female (and male) physicists. While there are many actions that can be taken at the personal, local, and even national level, it is necessary to understand when the issues have broader societal implications. Likewise, working toward the ideal environment should not lead us to ignore the necessity of training and assisting women to work effectively in the existing environment.

    Here is the intensely personal and often humorous autobiography of one of the most distinguished theoretical physicists of his generation, Sir Rudolf Peierls. Born in Germany in 1907, Peierls was indeed a bird of passage," whose career of fifty-five years took him to leading centers of physics--including Munich, Leipzig, Zurich, Copenhagen, Cambridge, Manchester, Oxford, and J. Robert Oppenheimer''s Los Alamos. Peierls was a major participant in the revolutionary development of quantum mechanics in the 1920s and 1930s, working with some of the pioneers and, as he puts it, "some of the great characters" in this field.

  12. Probabilistic interpretation of data a physicist's approach

    CERN Document Server

    Miller, Guthrie

    2013-01-01

    This book is a physicists approach to interpretation of data using Markov Chain Monte Carlo (MCMC). The concepts are derived from first principles using a style of mathematics that quickly elucidates the basic ideas, sometimes with the aid of examples. Probabilistic data interpretation is a straightforward problem involving conditional probability. A prior probability distribution is essential, and examples are given. In this small book (200 pages) the reader is led from the most basic concepts of mathematical probability all the way to parallel processing algorithms for Markov Chain Monte Carlo. Fortran source code (for eigenvalue analysis of finite discrete Markov Chains, for MCMC, and for nonlinear least squares) is included with the supplementary material for this book (available online).

    2002-01-01

    The author, a former American chemistry professor, has organized his book into nine parts with 29 chapters, covering, in a fairly historical sequence and systematic conceptual progression, all fundamentals of today's physics: i.e., mechanics, thermodynamics, electromagnetism, statistical mechanics, relativity, quantum mechanics, nuclear physics, particle physics, astronomy-astrophysics-cosmology. Obviously, the 20th century (when about 90% of professional physicists of all time worked) assumes with five topics the dominant role in this enterprise.

In addition, Cropper provides each of the topics with a short 'historical synopsis' justifying his selection of key persons. One may argue that concentrating on leading physicists constitutes an old-fashioned approach to displaying the history and contents of fundamental topics in physics.

In general, the presentation of the material is quite satisfactory (with only few slips, e.g., in the Meitner story, where the author follows too closely a new biography) and gives the essence of the great advances in physics since the 15th century. One notices perhaps the limitation of the author in cases where no biography in English is available - this would also explain the omission of some of the main contributors to atomic and particle physics, such as Arnold Sommerfeld and Hideki Yukawa, or that French or Russian

    Geoscience disciplines are filled with visual displays of data. From the first cave drawings to remote imaging of our Planet, visual displays of information have been used to understand and interpret our discipline. As practitioners of the art, visuals comprise the core around which we write scholarly articles, teach our students and make every day decisions. The effectiveness of visual communication, however, varies greatly. For many visual displays, a significant amount of prior knowledge is needed to understand and interpret various representations. If this is missing, key components of communication fail. One common example is the use of animations to explain high density and typically complex data. Do animations effectively convey information, simply "wow an audience" or do they confuse the subject by using unfamiliar forms and representations? Prior knowledge impacts the information derived from visuals and when communicating with non-experts this factor is exacerbated. For example, in an advanced geology course fractures in a rock are viewed by petroleum engineers as conduits for fluid migration while geoscience students 'see' the minerals lining the fracture. In contrast, a lay audience might view these images as abstract art. Without specific and direct accompanying verbal or written communication such an image is viewed radically differently by disparate audiences. Experts and non-experts do not 'see' equivalent images. Each visual must be carefully constructed with it's communication task in mind. To enhance learning and communication at all levels by visual displays of data requires that we teach visual literacy as a portion of our curricula. As we move from one form of visual representation to another, our mental images are expanded as is our ability to see and interpret new visual forms thus promoting life-long learning. Visual literacy is key to communication in our visually rich discipline. What do you see?

    This week saw the First International School on Laser Applications at Accelerators held in GANIL (France). Organised by the LA3NET project – of which CERN is a partner – the school was a singular opportunity for accelerator and laser physicists to meet and discuss the future of the merging areas.   As an EU-funded training network, LA3NET has brought together 27 partner institutes to train early stage researchers in the field of laser applications. Though the network kickedoff only a few months ago, it has already filled 15 of its 17 fellow positions, including three in CERN’s BE and EN Departments. The five-day International School on Laser Applications at Accelerators was the first big event organised by LA3NET, and united participants from both inside and outside the project. “This was the first time a school had linked laser and accelerator physics at such a fundamental level,” says Carsten P.

  1. Why are there so few female physicists?

    CERN Multimedia

    Marianne Johansen

    Physics has always had a relatively low proportion of female students and researchers. In the EU there are on average 33% female PhD-graduates in the physical sciences, while the percentage of female professors amounts to 9% [1]. At CERN the proportion is even less with only 6.6 % of the research staff being women [2]. The fact that there is no proportional relationship between the number of PhD-graduates and professors also suggests women are less likely to succeed in an academic career than men [1]. A typical ATLAS plenary meeting. More laptops than women... Is the low representation of women in physics a problem, do we actually need more female physicists? In my view this question has to be answered from three perspectives, the perspective of society, the perspective of science and the perspective of women. The perspective of society Starting from the viewpoint of society, several issues can be raised. Firstly, physics is a field of innovation. Many technological advancements having a huge imp...

  4. A physicist's views on energy problems

    International Nuclear Information System (INIS)

    Revol, Ch.J.P.

    2003-01-01

    The energy problem is one of the most serious challenges facing our civilization. The issue is not whether there are sufficient energy resources in the short- or medium-term, even though world consumption is already considerable, but rather how can we satisfy the world's current and future energy requirements without compromising the planet's ecological balance and how can we ensure an equitable distribution of an acceptable level of energy resources between all countries, including developing countries? The problem has now become a worldwide one with consequences that are also world-wide. The developed countries have lost control of the Earth's ecological future. In 1990 the developing countries consumed only a quarter of the world's energy resources. By 2020 they will already be consuming 60 %. New environmental) friendly technologies will have to be invented to produce sufficient energy at competitive prices. It is not just in the interests of the developed countries to help developing countries to acquire these new technologies, it is also their moral duty to do so. Any injunction to the developing countries not to burn coal and oil as we have done to date would be indefensible. Nuclear energy appears to be one of the possible ways of combating global warming since it produces no CO 2 and is currently the only source or energy capable of meeting demand for several centuries at least. This is the general background to the proposal of Carlo Rubbia and his team of CERN physicists for a new way of exploiting nuclear fission energy which addresses the question: can one imagine fission-based nuclear energy that would be acceptable to our society in other words, an ecological source of nuclear energy?

The situation has changed slowly since 2008. However, the study shows that women physicists more clearly understand the inequities and the need for changes, including an active European Union mainstreaming policy targeted to ensure gender equality in the sciences, which gives hope for accelerating changes. Continued plans for improving women physicists' situation in Lithuania are discussed.

    The negligent performance of professional duties is the most probable type of legal action against a medical physicist. A mistake resulting from ignorance or inadvertence is an example; an error in professional judgement is not negligence if an ordinary, prudent physicist in the same situation would have made the same decision. A physicist or any hospital employee has a duty to protect his employer from liability even to the extent of reporting to the hospital medical practices which could harm the patient. Suggestions for reducing legal risk include recommendations for professional knowledge, record keeping and outside verification of important elements of operating systems

    Medical physicists make a major contribution to the safe and effective diagnosis and treatment of patients with cancer and other illnesses. The medical physicist's responsibilities include the major areas of dosimetry, treatment planning, quality assurance, image quality, optimization, equipment management, research, teaching, and radiation safety. With the increasing complexity of technological application to medicine the competence of trained physicists is critical to good patient care, with counter examples, sadly evident in the literature. The International Atomic Energy Agency (IAEA), in conjunction with international experts, including from Japan, has developed clinical training programmes that have been successfully implemented on a pilot basis in a number of countries in Asia. A new project is to begin in 2014 which will focus increasingly on the use of electronic teaching material and experiences, to assist medical physicists in clinical training increasingly in more remote locations in Asia.

    Focus in this discussion of the Holy See is on geography, the people, history, government and institutions, foreign relations, and relations with the US and the Holy See. Vatican City occupies 0.439 square kilometers (109 acres). Some 1000 individuals live within the Vatican's walls, most of whom are Italian or Swiss by nationality. Vatican citizenship usually is accorded only to those who reside in Vatican City by reason of office or employment and, with certain restrictions, to their families. The Pope delegates the internal administration of Vatican City to the Pontifical Commission for the State of the Vatican City, headed by the Cardinal Secretary of State. The legal system is based on canon law or the laws of the city of Rome. On February 11, 1929, the Holy See and the Italian government signed 3 agreements regulating a dispute since 1871 about the Law of Guarantees, law which sought to assure the Pope's spiritual freedom, an income, and special status for the Vatican area. The agreements include: a treaty recognizing the independence and sovereignty of the Holy See and creating the State of the Vatican City; a concordat fixing the relations between the government and the church within Italy; and a financial convention providing the Holy See with compensation for its losses in 1870. The Pope, at this time John Paul II, exercises supreme legislative, executive, and judicial power over the Holy See and within the State of the Vatican City. The Pope rules the Holy See through the Roman Curia and Papal Civil Service, which staffs it. The Holy See, which carries on an active diplomacy of considerable scope and variety, is particularly active diplomatically in international organizations. The US maintained consular relations with the Papal States from 1797-1870 and diplomatic relations with the Pope in his capacity as head of the Papal States. These relations lapsed with the final loss of all papal territories in 1870. In 1984, the US and the Holy See announced the

    Full text: Medical radiology is chronologically the first and widest field of work of medical physicists. Therefore the education and training of medical radiological physicists is of big importance for both diagnostics and therapy. The education of medical radiological physicists in Bulgaria is organized in two levels: university and postgraduate, which is a good achievement of Bulgarian educational system. University education is in the framework of the M. Sc. program in Medical physics with a prevalent training in medical radiological physics. Three universities in the country have been carrying out this education since more than ten years. Postgraduate education covers specialties Medical Radiological Physics and Radiation Hygiene. It is organized by the Medical University but the training is opened also to specialists outside the health care system. The interests in both levels of education and training in Medical Physics is increasing with about 40 trainees in last years. The university and postgraduate education has good quality in theory but still inadequate in practical aspects. The continuous training and qualification of medical physicists has also difficulties; the main reasons are insufficient technical and financial resources as well as the lack of interest of the staff of the training centers. The responsibilities for education and training of medical physicists in radiology should be shared between physicists and physicians in the country

    2005-03-01

    In May 2002 there was a backpage article published in American Physical Society Newsletter by the President of the National Society of Black Physicists (NSBP). This article showed that of the 3372 professional physicists employed at the DOE national labs, only 11 are African American, which on a percentage basis is 4 times less than the total availability of Ph.D. African American physicists in the labor force. NSBP want to provide an update of the interaction between National Society of Black Physicists (NSBP) and the department of Energy in particular the Office of Science on the issue of employment of African American Physicists in scientific and technical. You might ask the following question: Why should the current generation of African American Physicists be concerned about their underepresentation on the scientific staffs of the DOE National Laboratories? The answer to this question may vary from person to person, but I would like to propose the following: The National Laboratories are the largest providers of career opportunities in Physics in the United States. There is a general view in the community; African Americans are not getting a return on their national investment in the DOE National Labs. Failure to engage with HBCU’s through their user facilities causes a training or skills deficit when it comes to preparing students to participate at the forefront of physics research. By rebuffing interactions with HBCU¹s, as many the laboratories have done, the national laboratories are in effect refusing to transfer scientific knowledge to the stakeholders in the African American community. The update will contain some additional information about NSBP proposals to solve the problem of underepresentation of African American and Hispanic physicists within the National Laboratories and how the Office of Science has response these proposals.

  3. TU-F-BRD-01: Biomedical Informatics for Medical Physicists

    International Nuclear Information System (INIS)

    Phillips, M; Kalet, I; McNutt, T; Smith, W

    2014-01-01

    Biomedical informatics encompasses a very large domain of knowledge and applications. This broad and loosely defined field can make it difficult to navigate. Physicists often are called upon to provide informatics services and/or to take part in projects involving principles of the field. The purpose of the presentations in this symposium is to help medical physicists gain some knowledge about the breadth of the field and how, in the current clinical and research environment, they can participate and contribute. Three talks have been designed to give an overview from the perspective of physicists and to provide a more in-depth discussion in two areas. One of the primary purposes, and the main subject of the first talk, is to help physicists achieve a perspective about the range of the topics and concepts that fall under the heading of 'informatics'. The approach is to de-mystify topics and jargon and to help physicists find resources in the field should they need them. The other talks explore two areas of biomedical informatics in more depth. The goal is to highlight two domains of intense current interest--databases and models--in enough depth into current approaches so that an adequate background for independent inquiry is achieved. These two areas will serve as good examples of how physicists, using informatics principles, can contribute to oncology practice and research. Learning Objectives: To understand how the principles of biomedical informatics are used by medical physicists. To put the relevant informatics concepts in perspective with regard to biomedicine in general. To use clinical database design as an example of biomedical informatics. To provide a solid background into the problems and issues of the design and use of data and databases in radiation oncology. To use modeling in the service of decision support systems as an example of modeling methods and data use. To provide a background into how uncertainty in our data and knowledge can be

  4. Clinical Training of Medical Physicists Specializing in Nuclear Medicine

    International Nuclear Information System (INIS)

    2011-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists who are based in a clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement for Research, Development and Training related to Nuclear Science and Technology (RCA) for the Asia-Pacific region. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in this region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in nuclear medicine was started in 2009 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experience of clinical training in Australia, Croatia and Sweden and was moderated by physicists working in the Asian region. The present publication follows the approach of earlier IAEA publications in the Training Course Series, specifically Nos 37 and 47, Clinical Training of Medical Physicists Specializing in Radiation Oncology and Clinical Training of Medical Physicists

  5. Introduction to Mathematica® for Physicists

    Science.gov (United States)

    Grozin, Andrey

    We were taught at calculus classes that integration is an art, not a science (in contrast to differentiation—even a monkey can be trained to take derivatives). And we were taught wrong. The Risch algorithm (which is known for decades) allows one to find, in a finite number of steps, if a given indefinite integral can be taken in elementary functions, and if so, to calculate it. This algorithm has been constructed in works by an American mathematician Risch near 1970; many cases were not analyzed completely in these works and were later considered by other mathematicians. The algorithm is very complicated, and no computer algebra system implements it fully. Its implementation in Mathematica is rather complete, even with extensions to some classes of special functions, but details are not publicly known. Strictly speaking, it is not quite an algorithm, because it contains algorithmically unsolvable subproblems, such as finding out if a given combination of elementary functions vanishes. But in practice computer algebra systems are quite good in solving such problems. Here we shall consider, at a very elementary level, the main ideas of the Risch algorithm; see [16] for more details.

  6. Accreditation of physicist in radiotherapy-past, present and future

    International Nuclear Information System (INIS)

    Howlett, S.

    2010-01-01

    Full text: Accreditation of medical physicists for clinical radiotherapy practice was commenced by the ACPSEM in 1988 by a group of experienced physicists interested in setting a benchmark of international standard by which to assess practising radiotherapy physicists. It is a voluntary, peer based examination process and leads to the award of Accreditation in Radiotherapy Equipment Commissioning and Quality Assurance (ARECQA). The responsible body within the ACPSEM is the Radiation Oncology Accreditation Panel (ROAP) under the umbrella of the Professional Standards Board(PSB). Over 130 physicists in Australia and New Zealand have been awarded ARECQA and it has been recognised by the radiotherapy professions and government bodies as a desirable and sometimes required, standard of qualification. With the implementation of the Training, Education and Accreditation Program (TEAP) by ACPSEM in 2003, a new Accreditation in Radiation Oncology Medical Physics (AROMP) was established in 2005. ARECQA will cease taking applications from experienced physicists on December 31st 2012 and only the AROMP pathway will be available. An external review of TEAP funded by the Commonwealth Government Department of Health and Ageing (DoHA), which is not yet publicly released, will have implications for AROMP in the future. This talk will review the development and progress of accreditation in radiation oncology medical physics in Australia and New Zealand, its place in the delivery of quality patient care, the relationship to ACPSEM registration, the current situation and future directions.

  7. How we see poverty

    Directory of Open Access Journals (Sweden)

    Jonathan Morduch

    2012-06-01

    Full Text Available How we think about poverty is colored by how we measure it. For economists, that often means seeing poverty through quantities measured in large, representative surveys.  The surveys give a comprehensive view, but favor breadth over depth. Typical economic surveys are limited in their ability to tease out informal activity, and, while they capture yearly sums, they offer little about how the year was actually lived by families. Year-long financial diaries provide a complementary way of seeing poverty, with a focus on week by week choices and challenges. The result is a re-framing of poverty and its relationship to money, calling for greater attention to financial access and a broader notion of how finance matters.

    A Japanese advanced charged particle therapy for cancer that places fewer physical burdens on patients is leading the world and stereotactic radiotherapy and intensity-modulated radiotherapy (IMRT) have been implemented also as a high precision radiotherapy. For the further advancement and dissemination of the therapy, training and qualification of medical physicists has become more needed. Cancer professional train course plan has been performed at many universities in Japan partly to train medical physicists. This special issue consists of seven relevant articles from experts of academia. Medical physicists have been qualified by the Japan Radiological Society, but should have national qualification such as to carry out the R and D of therapy equipment. This has been supported by many academia such as the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) but not by the Japan Association of Radiological Technologists (JART). (T.

  11. What physicists should learn about finance (if they want to)

    Schmidt, Anatoly

    2006-03-01

    There has been growing interest among physicists to Econophysics, i.e. analysis and modeling of financial and economic processes using the concepts of theoretical Physics. There has been also perception that the financial industry is a viable alternative for those physicists who are not able or are not willing to pursue career in their major field. However in our times, the Wall Street expects from applicants for quantitative positions not only the knowledge of the stochastic calculus and the methods of time series analysis but also of such concepts as option pricing, portfolio management, and risk measurement. Here I describe a synthetic course based on my book ``Quantitative Finance for Physicists'' (Elsevier, 2004) that outlines both worlds: Econophysics and Mathematical Finance. This course may be offered as elective for senior undergraduate or graduate Physics majors.

  12. Clinical Training of Medical Physicists Specializing in Diagnostic Radiology

    International Nuclear Information System (INIS)

    2010-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology. This approach to clinical training has been successfully tested

    Over the past several decades, physicists have made seminal contributions to technological capabilities that have enabled the U.S. intelligence community to provide unexpected and unparalleled information to our nation's decision makers and help dispel the cloud of uncertainty they face in dealing with crises and challenges around the world. As we look to the future, we recognize that the ever-quickening pace of changes in the world and the threats we must confront demand continued innovation and improvement in the capabilities needed to provide the information on which our leaders depend. This talk will focus on some of the major technological challenges that the intelligence community faces in the coming years, and the many ways that physicists can help to overcome those challenges. The potential impact of physicists on the future capabilities of the US intelligence community is huge. In addition to the more obvious and direct impact through research in areas ranging from novel sensors to quantum information science, the unique approach physicists bring to a problem can also have an indirect but important effect by influencing how challenges in areas ranging from cybersecurity to advanced analytics are approached and solved. Several examples will be given.

    2003-07-01

    The first meeting of African American physicists was held in 1973 at Fisk University in Nashville, Tennessee, with around 50 Black physicists in attendance. In 1977, this organization was formally established as the National Society of Black Physicists (NSBP) out of a need to address many concerns of African American physicists. During the ensuing years the Conference began to grow and was hosted by different institutions at various geographic locations. This year, the 2003 Annual Conference of the National Society of Black Physicists and Black Physics Students was hosted by Spelman College in Atlanta, Georgia during the weekend of February 12th-15th, 2003. This Conference brought together over 500 African American physics students and working physicists. Also attending were corporate and graduate school recruiters, administrators, professional society representatives and others concerned with the small representation of minorities in the field of physics. The organizers of the Conference contracted with the Statistical Research Center of the American Institute of Physics to conduct a formal evaluative study of the meeting, resulting in this report. The evaluation questionnaire was designed by the organizers of the NSBP conference with input from the Statistical Research Center's staff. It included questions on the students' backgrounds and demographic characteristics, physics research experience, career goals, challenges faced in their academic pursuits, and ratings of various aspects of the conference. The questionnaire was distributed at the conference when the students signed in. Of the 330 students who were registered, roughly 304 attended and were given the four-page questionnaire to complete. Responses were collected on the last night of the conference, with 172 (approximately 57%) returning completed questionnaires. This low response rate could be attributed in part to the fact that respondents were asked to provide possibly sensitive personal

    2008-01-01

    Full Text Available Introduction: Medical Physicist, as a professional who works in a hospital environment, is a member of a wide clinical team which is responsible for the correct diagnosis and the therapeutic methods applied using radiation. The role of a Medical Physicist is multifold and consists of the estimation of the dose received by patients and personnel, the quality control of radiological equipment, the studies for shielding requirements and the training of several health professionals (doctors, medical physicists, radiologists, technicians, nurses. All the above are prerequisites in order to receive the professional license to act as Medical Physicist.Aim-Research Inquires: The aim of European Union (EU via European Federation of Medical Physics (EFOMP is to apply a common policy among the EU countries in the area of Education and Training in Medical Physics within the context of the current developments in the European Higher Education Area arising from “The Bologna Declaration”. A short-term perspective is the free movement of professionals within EU, via the assurance of knowledge and skills uniformity. A necessary preliminary stage is the collection, classification and further process of relevant information at the European level.Methods-Techniques: To achieve the above in an efficient way EFOMP prepared a questionnaire and sent it to the National Organisation for Medical Physics of each country member of EFOMP (NMO. 23 out of 34 country members responded. The main parts (3 in total of this questionnaire and some typical questions were:Part A: Medical Physics Education•Which degree is required? Is this a university degree? How many years of studies does it represent?•Is there a nationally approved education programme and, if yes, then by whom?•Where do the education and training take place (University, Hospital, or both of them? Are these centers accredited and who gives the accreditation?Part B: Qualified / Specialist Medical Physicist

  12. Clinical Training of Medical Physicists Specializing in Radiation Oncology

    International Nuclear Information System (INIS)

    2009-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for radiation therapy. There is a general and growing awareness that radiation medicine is increasingly dependant on well trained medical physicists that are based in the clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognised by the members of the Regional Cooperative Agreement (RCA) for research, development and training related to nuclear sciences for Asia and the Pacific. Consequently a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in radiation therapy was started in 2005 with the appointment of a core drafting committee of regional and international experts. Since 2005 the IAEA has convened two additional consultant group meetings including additional experts to prepare the present publication. The publication drew heavily, particularly in the initial stages, from the experience and documents of the Clinical Training Programme for Radiation Oncology Medical Physicists as developed by the Australasian College of Physical Scientists and Engineers in Medicine.

  13. The role of the health physicist in nuclear security.

    Waller, Edward J; van Maanen, Jim

    2015-04-01

    Health physics is a recognized safety function in the holistic context of the protection of workers, members of the public, and the environment against the hazardous effects of ionizing radiation, often generically designated as radiation protection. The role of the health physicist as protector dates back to the Manhattan Project. Nuclear security is the prevention and detection of, and response to, criminal or intentional unauthorized acts involving or directed at nuclear material, other radioactive material, associated facilities, or associated activities. Its importance has become more visible and pronounced in the post 9/11 environment, and it has a shared purpose with health physics in the context of protection of workers, members of the public, and the environment. However, the duties and responsibilities of the health physicist in the nuclear security domain are neither clearly defined nor recognized, while a fundamental understanding of nuclear phenomena in general, nuclear or other radioactive material specifically, and the potential hazards related to them is required for threat assessment, protection, and risk management. Furthermore, given the unique skills and attributes of professional health physicists, it is argued that the role of the health physicist should encompass all aspects of nuclear security, ranging from input in the development to implementation and execution of an efficient and effective nuclear security regime. As such, health physicists should transcend their current typical role as consultants in nuclear security issues and become fully integrated and recognized experts in the nuclear security domain and decision making process. Issues regarding the security clearances of health physics personnel and the possibility of insider threats must be addressed in the same manner as for other trusted individuals; however, the net gain from recognizing and integrating health physics expertise in all levels of a nuclear security regime far

Dwarf galaxies are relatively small collections of stars that often orbit around larger galaxies like our Milky Way. The forming dwarf galaxies shine in the far ultraviolet spectrum, rendered as blue in the call-out on the right hand side of this image. Near ultraviolet light, also obtained by the Galaxy Evolution Explorer, is displayed in green, and visible light from the blue part of the spectrum here is represented by red. The clumps (in circles) are distinctively blue, indicating they are primarily detected in far ultraviolet light. The faint blue overlay traces the outline of the Leo Ring, a huge cloud of hydrogen and helium that orbits around two massive galaxies in the constellation Leo (left panel). The cloud is thought likely to be a primordial object, an ancient remnant of material that has remained relatively unchanged since the very earliest days of the universe. Identified about 25 years ago by radio waves, the ring cannot be seen in visible light. Only a portion of the Leo Ring has been imaged in the ultraviolet, but this section contains the telltale ultraviolet signature of recent massive star formation within this ring of pristine gas. Astronomers have previously only seen dwarf galaxies form out of gas that has already been cycled through a galaxy and enriched with metals elements heavier than helium produced as stars evolve. The visible data come from the Digitized Sky Survey of the Space Telescope Science Institute in Baltimore, Md. The Leo Ring visible image (left

    2016-01-01

    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

  1. The duty health physicist program at Byron Nuclear Power Station

    International Nuclear Information System (INIS)

    Goldsmith, D.G.; Carey, T.R.

    1987-01-01

    The Duty Health Physicist Program at Byron Station was established to deal with routine health physics tasks and provide an interface between frontline and upper radiation-chemistry management. The program consists of a weekly rotation of selected members of the health physics staff into the duty health physicist position to handle the assigned duty tasks. The tasks include, but are not limited to, daily isotopic and air sample review, effluent release package review, maximum permissible concentration calculations, dose approvals, as-low-as-reasonably-achievable action review of pending jobs, and general availability to answer questions and address problems in health-physics-related areas of plant operation. The daily attendance of the duty health physicist at the radiation-chemistry and station plan-of-the-day meetings has increased the overall presence and visibility of the health physics program to upper station management and other station departments. Since its inception in July of 1985, the Duty Health Physics Program has been a major contributor to the observed 50% reduction in reportable personnel errors in the radiation-chemistry department (based on personnel-error-related deviation reports and license event reports generated on the radiation-chemistry department at Byron Station). Although difficulty to quantify, other important benefits of this program are also discussed in this paper

    2015-07-01

    To standardize educational programs and clinical training for medical physics students, the Japanese Board for Medical Physicist Qualification (JBMP) began to accredit master's, doctorate, and residency programs for medical physicists in 2012. At present, 16 universities accredited by the JBMP offer 22 courses. In this study, we aimed to survey the current status of educational programs and career paths of students after completion of the medical physicist program in Japan. A questionnaire was sent in August 2014 to 32 universities offering medical physicist programs. The questionnaire was created and organized by the educational course certification committee of the JBMP and comprised two sections: the first collected information about the university attended, and the second collected information about characteristics and career paths of students after completion of medical physicist programs from 2008 to 2014. Thirty universities (16 accredited and 14 non-accredited) completed the survey (response rate 94 %). A total of 209, 40, and 3 students graduated from the master's, doctorate, and residency programs, respectively. Undergraduates entered the medical physicist program constantly, indicating an interest in medical physics among undergraduates. A large percentage of the students held a bachelor's degree in radiological technology (master's program 94 %; doctorate program 70 %); graduates obtained a national radiological technologist license. Regarding career paths, although the number of the graduates who work as medical physicist remains low, 7 % with a master's degree and 50 % with a doctorate degree worked as medical physicists. Our results could be helpful for improving the medical physicist program in Japan.

    Doing Physics makes concepts of physics easier to grasp by relating them to everyday knowledge. Addressing some of the models and metaphors that physicists use to explain the physical world, Martin H. Krieger describes the conceptual world of physics by means of analogies to economics, anthropology, theater, carpentry, mechanisms such as clockworks, and machine tool design. The interaction of elementary particles or chemical species, for example, can be related to the theory of kinship-who can marry whom is like what can interact with what. Likewise, the description of physical situations i

    2007-03-01

    A traditional education in physics does not normally include business classes or dealing with opportunities to start a company, yet scientists often now start and run small companies. Physicists are mainly interested in technology. However, other factors quickly dominate chances for business success. These include finance, accounting, cash flow analysis, recruiting, interviewing, personnel issues, marketing, investments, retirement plans, patents and other not always so fun activities. Technical decisions are often strongly influenced by company finances and market-analysis. This talk discusses how to recognize opportunity, how to minimize chances for failure, and lifestyle changes one needs to be aware of before entrepreneurship involvement.

    The 1991 School for Young High Energy Physicists was attended by 44 first year graduate students - probably the largest number since it was started in 1972. It took place in September, at the Cosener's House, Abingdon, and was organised and funded by Rutherford Appleton Laboratory. Published here are the lectures that were given in the mornings. These were supplemented and reinforced by the work in the afternoons, which were devoted to problems and tutorials. At the end of the intensive two week course the students emerged exhausted, but with a thorough grounding in the Standard Model of Elementary Particle Physics, on which most of them are performing their experimental work.

    By training, a physicist possesses one of the rarest qualities ever imparted in an educational degree program, namely, the ability to take on complex problems, divide them into ``solvable'' parts, derive solutions and put them back as insightful outputs. Dr Bhattacharya, CEO of Salorix, a research, analytics and consulting firm, explains how he has used these skills learned at the graduate school to build a career as a scientist, management consultant and entrepreneur. He will also speak about how the real-life skillsets of understanding and dealing with ``Inflections'', self discovery and introspection can be a great tool for managing one's life and career progression.

    High-energy physicists' current explanation for the behavior of subatomic particles and forces, known as the Standard Model, is doing just fine. That was the take-home message for the 800 delegates who gathered here from 27 July to 2 August for the international Europhysics Conference on High-Energy Physics. open-quotes Mainly this was a conference of consolidation, steady progress, many very beautiful and detailed results,close quotes Christopher Llewellyn Smith, director general of CERN, the European particle physics laboratory, told Science. But while a multitude of presentations described ever more accurate tests and confirmations of the model, physicists also discussed hints that a whole new range of phenomena beyond the Standard Model is lurking just above the energies of current accelerators-and within range of the next generation of experiments. Other topics covered in this meeting report include the practical side of detecting and recording events in future particle accelerators and some new information on the elusive neutrino

  18. A Physicist's Journey In The Nuclear Power World

    Science.gov (United States)

    Starr, Chauncey

    2000-03-01

    As a participant in the development of civilian nuclear power plants for the past half century, the author presents some of his insights to its history that may be of interest to today's applied physicists. Nuclear power development has involved a mixture of creative vision, science, engineering, and unusual technical, economic, and social obstacles. Nuclear power programs were initiated during the euphoric era of public support for new science immediately following World War II -- a support that lasted almost two decades. Subsequently, nuclear power has had to face a complex mix of public concerns and criticism. The author's involvment in some of these circumstances will be anecdotally described. Although the physics of fission and its byproducts remains at the heart of all nuclear reactor designs, its embodiment in practical energy sources has been shaped by the limitations of engineering primarily and economics secondarily. Very influential has been the continuing interplay with the military's weapons and propulsion programs, and the government's political policies. In this respect, nuclear power's history provides a learning experience that may be applicable to some of the large scale demonstration projects that physicists pursue today.

    2002-01-01

    Up until the end of the 1970s you could still catch a glimpse of his massive silhouette in the corridors of CERN. Lew Kowarksi, one of the pioneers of the Laboratory, was not only a great physicist; he was also a genuine hero of World War II. In 1940, along with Frédéric Joliot and Hans von Halban, Lew Kowarski managed to get the entire world supply of heavy water away to safety from the Nazis after a fantastic escape from occupied France. At the end of the war, the three physicists played themselves in a film about their adventures entitled 'la Bataille de l'eau lourde'. This film, which has been loaned to us by the French National Film Library, will be shown at CERN for the first time next Thursday. At the beginning of the war, heavy water (D20, two atoms of deuterium and one oxygen atom) was of strategic importance. In 1939 Frédéric Joliot, aided by Hans von Halban and Lew Kowarski, demonstrated the nuclear chain reaction and the moderator role that heavy water plays in it. A few weeks before the inv...

  20. Got Skills? On-the-Job Activities of Physicists

    2011-03-01

    It goes almost without saying that physics doctorates do a lot more than just physics research or teaching at their jobs. But what exactly do they do? First, I will share basic data showing where physics doctorates are employed. Then I will present data from two of AIP's surveys about the employment of physicists. The first set of data comes from our survey of physics PhDs one year after doctorate. We will consider how often physics doctorates do a variety of activities on the job, including management, technical writing, teamwork, design and development, programming, and advanced mathematics. The second set of data comes from AIP's new survey of PhDs in physics 10 to 13 years after graduation. Data for many of the same activities will be shown for physics doctorates who have been in the workplace about a decade. Depending on the type of job, most industrially employed physics doctorates do some type of physics at work, but they are also very likely to report managing projects, writing for technical audiences, working on a team, and collaborating with non-physicists, among many other activities. This examination of the types of activities physics doctorates perform in the workplace will provide insight on the non-scientific training that would benefit graduate students the most.

  1. You Don't Look Like a Physicist

    Santos, Antonio Carlos Fontes

    "You don't look like a physicist!" "Sorry, this bus only goes to the university, Sir." "Where are you going, sir?" "So, you are a university professor? But a substitute one, aren't you?" "OK, you're a professor, but do you do research?" As a person of color teaching physics in Brazil, those are some comments that I usually hear. They are consequences of stereotypes, prejudices, and discrimination, which are related but different ideas. Stereotypes indicate expectations and beliefs about an individual or a group, prejudice denotes feelings, and discrimination expresses behaviors. People are likely to be astonished whenever a Black person says that he or she is a physicist. This paper aims to raise awareness of the underrepresentation of Black physics professors and researchers in Brazil and how the lack of quality high school physics education impacts Black and poor students in Brazil. Finally, some considerations on how physics education can assist minority students in overcoming social barriers that contribute to their underrepresentation are presented.

  2. Nuclear forces the making of the physicist Hans Bethe

    2012-01-01

    On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by "Nuclear Forces", a riveting biography of Bethe's early life and development as both a scientist and a man of principle. As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems h...

  3. Reflections at La Rabida: the responsibilities of the nuclear physicist for peace

    1988-01-01

    Atomic energy was first applied to war but it was successful in its aim of bringing about peace. Nuclear physicists have been responsible for many momentous changes in world history. Their continuing responsibility to see that the public debates on nuclear issues of both war and peace are conducted with due regard for the essential scientific facts. Attempts by nuclear scientists to influence political decisions, through Pugwash meetings and Non-Poliferation treaties are discussed in an historical context. It is concluded that the anti-nuclear activists have won the propaganda battle about nuclear power - scientists have lost the battle to convey the facts about nuclear physics and especially nuclear safety to the public. Risks from nuclear power are perceived as great whereas in fact they are very small. Wise decisions cannot be made until the facts are known. The media is saturated with false information. Those who know the facts are unable to make their voices heard. This is exceedingly dangerous for our society. (UK)

  4. An Unbiased View of the History of Polish Medical Physics by a Senior Polish Medical Physicist

    Chomicki, O. A.

    2008-01-01

    Here is a story told by Maria Sklodowska-Curie at the meeting of the International Committee of Intellectual Cooperation in 1921: 'In a free literary competition on the role and importance of elephants the Englishman's story was 'My adventures while shooting elephants in South Africa', the Frenchman was more concerned with 'The sexual and erotic life of elephants', while the Polish approach was invariably 'The elephant versus Poland's national independence', which seemed quite understandable in the light of over 120 years when Poland was partitioned and lost its independence. Since then this saying has become proverbial and came to express the unmistakably Polish tendency to see everything in terms of Polish interests. In my remarks and reminiscences on the history of the Polish Society of Medical Physics you will quickly recognize the same tendency. First, I will, among other things, try to open some old cupboards to 'produce good [things] from the store of good' (Matthew 12:35), especially concerning the first few years of the activity in medical physics in Poland, and second, I will draw some conclusions and/or offer suggestions based on what a senior medical physicist has seen for more than 50 years of his activity in this field.

  5. Thirty year celebration of the contribution of nuclear medicine physicists in Australia

    2007-01-01

    Full text: The intention of this article is to describe the contributions of the many nuclear medicine physicists who in a large or small way have added to the ongoing development of nuclear medicine in Australia from the first years of the discipline in the late 1960s to the present time. Unlike our colleagues in radiation oncology physics, the nuclear medicine physicist fraternity has always been a very small group which unfortunately has not expanded greatly over the 30 years and beyond. This is emphasized in the survey by W.H.Round 1 which showed the bias towards older physicists being involved in the discipline. Because of the small numbers of nuclear medicine physicists in the public hospital system, mostly one or two per teaching hospital, most physicists are heavily involved in clinical duties to keep up the high standard of equipment and software performance required. Many nuclear medicine physicists also have the dual role of hospital radiation safety officers which is becoming more demanding as radiation legislation increases. For this reason much of the pure research has been confined to the hospitals with larger numbers of physicists. However a high proportion of nuclear medicine physicists across the country have contributed greatly to clinical research and development as part of their job. Unfortunately these cannot all be recognised in this article. Young physicists may not realise how much 'in house' research and development was carried out by physicists in the early years of nuclear medicine when equipment companies did not provide the software which is now available to purchase. Many of these innovative techniques and software, described in this article, are still in use today. Some of the 'big events' in the history of nuclear medicine in Australia in which physicists have played a leading role will also be highlighted. This will serve to emphasize how physicists have worked closely with clinicians and technologists in the ongoing development of

  6. Guerrilla science survival strategies of a Cuban physicist

    Altshuler, Ernesto

    2017-01-01

    Full of drama, dedication, and humor, this book narrates the author’s often frustrating experiences working as an experimental physicist in Cuba after the disintegration of the so-called socialist block. Lacking finance and infrastructure, faced with makeshift equipment, unpredictable supplies, and unreliable IT, Altshuler tells how he and his students overcame numerous challenges to make novel and interesting contributions to several fields of science. Along the way, he explains the science - from studies of ant colonies to superconductivity - either qualitatively or quantitatively, but always at a level fully understandable to an undergraduate student of natural sciences or engineering. An even wider audience, however, may skip the technical sections without missing the essence. With numerous anecdotes, photographs and the author’s own delightful cartoons, the book tells a remarkable, and often amusing story of how successful science can be performed against all odds.

    Ionizing Radiation is applied in Radiation Therapy, Nuclear medicine and Diagnostic Radiology. Radiation Protection in Medical Application of Ionizing Radiation requires specific Professional Competence in all relevant details of the radiation source instrumentation / equipment clinical dosimetry application procedures quality assurance medical risk-benefit assessment. Application in general include Justification of practices (sufficient benefit to the exposed individuals) Limitation of doses to individuals (occupational / public exposure) Optimization of Protection (magnitude and likelihood of exposures, and the number of individuals exposed will be ALARA. Competence of persons is normally assessed by the State by having a formal mechanism for registration, accreditation or certification of medical physicists in the various specialties (e.g. diagnostic radiology, radiation therapy, nuclear medicine). The patient safety in the use of medical radiation will be increased through: Consistent education and certification of medical team members, whose qualifications are recognized nationally, and who follow consensus practice guidelines that meet established national accrediting standards

    Medical physicists are often involved in the didactic training of graduate students, residents (both physics and physicians), and technologists. As part of continuing medical education, we are also involved in maintenance of certification projects to assist in the education of our peers. As such, it is imperative that we remain current concerning available educational resources. Medical physics journals offer book reviews, allowing us an opportunity to learn about newly published books in the field. A similar means of communication is not currently available for online educational resources. This information is conveyed through informal means. This review presents a summary of online resources available to the medical physics community that may be useful for educational purposes.

    The 1992 School for young High Energy Physicists took place from September 6-19, at the Cosener's House, Abingdon, and was attended by virtually all United Kingdom 1st year graduate students in the field of Experimental Particle Physics. It was organised and funded by the Rutherford Appleton Laboratory, whose assistance is very gratefully acknowledged. Published here are the lectures that were given in the mornings. These were supplemented and reinforced by the work in the afternoons, which were devoted to problems and tutorials. at the end of the intensive two week course the students emerged exhausted, but with a thorough grounding in the Standard Model of Elementary Particle Physics on which most of them are performing their experimental work.

  10. An introduction to tensors and group theory for physicists

    CERN Document Server

    Jeevanjee, Nadir

    2011-01-01

    An Introduction to Tensors and Group Theory for Physicists provides both an intuitive and rigorous approach to tensors and groups and their role in theoretical physics and applied mathematics. A particular aim is to demystify tensors and provide a unified framework for understanding them in the context of classical and quantum physics. Connecting the component formalism prevalent in physics calculations with the abstract but more conceptual formulation found in many mathematical texts, the work will be a welcome addition to the literature on tensors and group theory. Part I of the text begins with linear algebraic foundations, follows with the modern component-free definition of tensors, and concludes with applications to classical and quantum physics through the use of tensor products. Part II introduces abstract groups along with matrix Lie groups and Lie algebras, then intertwines this material with that of Part I by introducing representation theory. Exercises and examples are provided throughout for go...

    Forty-seven experimental particle physicists attended the 2002 Summer School, held, as usual, at The Cosener's House in Abingdon during September. The weather was glorious allowing a number of tutorials and impromptu seminars to take place in the lovely gardens. The lectures were of a high standard and were delivered and received enthusiastically, providing material for lively discussions in tutorials and elsewhere. The students each gave a ten-minute seminar and the general quality of the talks was impressive and the time keeping excellent. The activities described ranged from front-line physics analysis to preparations for the next generation of machines and detectors, and gave a clear indication of the breadth of particle physics activities in the UK

    Institute of Astronomy, University of Tokyo is now planning to build a 6.5-m optical-infrared telescope in Atacama, Chile. This project is called "Univ. Tokyo Atacama Observatory (TAO)", and the site evaluation is now under way. As a part of this evaluation process, we started an investigation to compare the astronomical seeing at Atacama with that at Mauna Kea. Here, we report preliminary results of seeing measurements at several sites in Atacama, carried out on October 2003. In order to separate the temporal and site-to-site variation of the seeing, we used two sets of Differential Image Motion Monitors (DIMMs), each of which has two pairs of 7.4 cm sub-apertures with 20.5 cm separation. Three sites were investigated; the point near the TAO weather station (4,950m), the summit of Cello Chico (5,150m) and the point at 5,430m altitude on Cello Toco. Simultaneous measurements were carried out for three half nights out of four half nights measurements. Although the amount of our data is very limited, the results suggest following: 1) Seeing becomes better and more stable as time passing to midnight (eg. From 0."7 to 0."4 at V-band). 2) Higher altitude sites show better seeing than lower altitude sites.

    2015-01-01

    The focus of work of medical physicists in 1980’s was on quality control and quality assurance. Radiation safety was important but was dominated by occupational radiation protection. A series of over exposures of patients in radiotherapy, nuclear medicine and observation of skin injuries among patients undergoing interventional procedures in 1990’s started creating the need for focus on patient protection. It gave medical physicists new directions to develop expertise in patient dosimetry and dose management. Publications creating awareness on cancer risks from CT in early part of the current century and over exposures in CT in 2008 brought radiation risks in public domain and created challenging situations for medical physicists. Increasing multiple exposures of individual patient and patient doses of few tens of mSv or exceeding 100 mSv are increasing the role of medical physicists. Expansion of usage of fluoroscopy in the hands of clinical professionals with hardly any training in radiation protection shall require further role for medical physicists. The increasing publications in journals, recent changes in Safety Standards, California law, all increase responsibilities of medical physicists in patient protection. Newer technological developments in dose efficiency and protective devices increase percentage of time devoted by medical physicists on radiation protection activities. Without radiation protection, the roles, responsibilities and day-to-day involvement of medical physicists in diagnostic radiology becomes questionable. In coming years either medical radiation protection may emerge as a specialty or medical physicists will have to keep major part of day-to-day work on radiation protection. Learning Objectives: To understand how radiation protection has been increasing its role in day-to-day activities of medical physicist To be aware about international safety Standards, national and State regulations that require higher attention to radiation

    In the 1980's and 90's, when every mammography department had a wet film processor and a sundial to keep the schedule, medical physicists performing mammography surveys were primarily focused on measuring machine performance and image quality. As our professional experience matured, medical physicists began to learn that they were uniquely qualified to help to recommend technique factors that would balance dose and image quality. Technique charts using different kVp, target-filter combinations and AEC modes gradually became common and patients benefitted from our input. With the revolutionary change in CT Scanner technology and utilization, medical physicists have begun to contribute their expertise to developing and improving CT protocols. This presentation will present practical challenges and offer some directions for the practicing medical physicist who desires to participate in this critical and emerging aspect of imaging physics practice: CT Protocol Review. © 2012 American Association of Physicists in Medicine.

    The cosmic microwave background provides constraints on the annihilation and decay of light dark matter at redshifts between 100 and 1000, the strength of which depends upon the fraction of energy ending up in the form of electrons and photons. The resulting constraints are usually presented for a limited selection of annihilation and decay channels. Here we provide constraints on the annihilation cross section and decay rate, at discrete values of the dark matter mass m{sub χ}, for all the annihilation and decay channels whose secondary spectra have been computed using PYTHIA in arXiv:1012.4515 (''PPPC 4 DM ID: a poor particle physicist cookbook for dark matter indirect detection''), namely e, μ, τ, V → e, V → μ, V → τ, u, d s, c, b, t, γ, g, W, Z and h. By interpolating in mass, these can be used to find the CMB constraints and likelihood functions from WMAP7 and Planck for a wide range of dark matter models, including those with annihilation or decay into a linear combination of different channels.

    The diagnostic studies and therapeutic treatments carried out in a Nuclear Medicine department make use of radioactive material. For such a reason it becomes necessary to take a strict control in the reception, use and waste that are generated of the typical works inside the department. Also, work related with the quality control of the equipment dedicated to produce images and of those not image formers, need to carry out to guarantee its maximum performance; as well as quality of the diagnostic and of the therapy imparted in patients. Additionally its are needed to make originated works of the individual procedures to patient and of the acquisition of radioactive materials and removal of the waste or radioactive contaminations. Presently work the recommendations of the American College of Radiology (ACR), the European Federation of Organizations for Medical Physics (EFOMP) and of the Mexican Official Standards relating to the functions that should be observed in a Nuclear Medicine Department are exposed. The ACR and the EFOMP, conclude in their recommendations that the medical physicist fulfills with the suitable profile and likewise they describe in detail the actions and functions that he should supervise, to carry out, to document and to inform.

    The broad and deep insight a physicist brings to the goings on in a large technology company lead to many varied and exciting opportunities. Examples in my own career include contributions to important understanding of new breakthroughs (understanding the basic anisotropy of high temperature superconductivity), bringing vital physics understanding to ambitious engineering projects (basic switching and noise margins in digital Josephson junction technology), and initiating and growing large applied projects based on fundamental physics breakthroughs (magnetoresistive random access memory - MRAM). Success at such undertakings within a large enterprise involves a number of factors. Always seeking out the best expert advice and the best collaborators in unfamiliar technical areas as new ideas develop is enormously helpful and not at all difficult within a large innovative organization. While being imaginative and optimistic, one must also remain brutally honest about the potential value of new endeavors, the hurdles ahead, and the likelihood of success. Always, however, there is no substitute hard work. I can attest that the results of efforts along these directions within a technology company can be very exciting and satisfying, and the process along the way a whole lot of fun.

  8. Discovery Mondays - The particle physicist's best friend: electricity

    CERN Document Server

    2005-01-01

    One of CERN's electrical substations, at Prévessin. Electricity is one of CERN's closest allies. Without it, none of the physicists' extraordinary instruments would work. It is electricity that will guide and accelerate particles around the 27-km ring of the world's most powerful accelerator, the LHC. In the giant magnets inside the experiments electricity is also used to produce a magnetic field 200,000 times greater than the Earth's own magnetic field. Inside the detectors, the resulting magnetic force is used to bend the trajectories of the particles, allowing them to be identified and helping us gain a better understanding of what has happened at the heart of the collisions. Understanding how magnetic fields are produced inside the ATLAS experiment is one of several themes on the programme of the next Discovery Monday. And for a close-up view of operations, we'll also be taking you on a visit to the electricity substation at Meyrin. Come and meet CERN's best friend - electricity. Join us at the Micro...

  9. PET: the importance of physicists for the clinical arena

    CERN Multimedia

    2005-01-01

    David Townsend giving a seminar at CERN on 9 February. The past few years have seen significant advances in the development of instrumentation for Positron Emission Tomography (PET). The recent appearance of combined PET and Computed Tomography (CT) scanners that can simultaneously image both anatomy and function is of particular importance. This was the main subject of "Advances in PET imaging: from physics to physician", a seminar presented at CERN by David Townsend on Wednesday 9 February  and organized by the TT and PH groups. David Townsend, who started his career at CERN in the 1970s, is now Professor at the Department of Medicine, University of Tennessee Medical Center (Knoxville, TN). Recipient of the 2004 Clinical Scientist of the Year Award, he is an internationally renowned researcher and PET physicist, with over 25 years of experience in the field. His 1999 image of the year, an award from the Society of Nuclear Medicine in the US, was produced using a combined state-of-the art PET and a true d...

  10. Becoming a Physicist: How Identities and Practices Shape Physics Trajectories

    Science.gov (United States)

    Quan, Gina M.

    This dissertation studies the relationships and processes which shape students' participation within the discipline of physics. Studying this early disciplinary participation gives insight to how students are supported in or pushed out of physics, which is an important step in cultivating a diverse set of physics students. This research occurs within two learning environments that we co-developed: a physics camp for high school girls and a seminar for undergraduate physics majors to get started in physics research. Using situated learning theory, we conceptualized physics learning to be intertwined with participation in physics practices and identity development. This theoretical perspective draws our attention to relationships between students and the physics community. Specifically, we study how students come to engage in the practices of the community and who they are within the physics community. We find that students' interactions with faculty and peers impact the extent to which students engage in authentic physics practices. These interactions also impact the extent to which students develop identities as physicists. We present implications of these findings for the design of physics learning spaces. Understanding this process of how students become members of the physics community will provide valuable insights into fostering a diverse set of successful trajectories in physics.

    The polarisation of prompt [Formula: see text] mesons is measured by performing an angular analysis of [Formula: see text] decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0[Formula: see text], collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum [Formula: see text] and rapidity [Formula: see text] in the kinematic region [Formula: see text] and [Formula: see text], and is compared to theoretical models. No significant polarisation is observed.

  12. Reconstructing see-saw models

    In this talk we discuss the prospects to reconstruct the high-energy see-saw Lagrangian from low energy experiments in supersymmetric scenarios. We show that the model with three right-handed neutrinos could be reconstructed in theory, but not in practice. Then, we discuss the prospects to reconstruct the model with two right-handed neutrinos, which is the minimal see-saw model able to accommodate neutrino observations. We identify the relevant processes to achieve this goal, and comment on the sensitivity of future experiments to them. We find the prospects much more promising and we emphasize in particular the importance of the observation of rare leptonic decays for the reconstruction of the right-handed neutrino masses

  13. Physicists band together to support a new megaproject

    As the Superconducting Super Collider (SSC) flirts with death in the congressional budget process for a second year, another mammoth science project is coming to life. Just a few days after the House voted to kill the $10 billion particle accelerator last month, it approved next year's funding for a megaproject that is a little cheaper and a lot less familiar: a $2.7 billion nuclear reactor known as the Advanced Neutron Source (ANS), to be built at Tennessee's Oak Ridge National Laboratory as a national facility for probing materials with beams of neutrons. The project's success in the House is a sign that physicists can still make a case for big science-at least when the project has a broad scientific constituency and plausible links to national competitiveness. When the facility is completed in 2002, it will be the world's most powerful neutron source, delivering 10 times the flux of neutrons produced by its nearest competitor, at the Institute Lau-Langevin in Grenoble, France. For now, designs call for a reactor about one-tenth the size of a power reactor, says project director West. Fission in the reactor core will send out a steady stream of neutrons. Slowed by heavy water to little more than walking speed, the neutrons will be carried through guides that work like fiber optic cables-by reflecting the neutrons internally, like tennis balls ricocheting down a pipe-to experiments tens or hundreds of meters away. There the neutrons will probe the atomic-scale structure of materials in a way that depends on quantum mechanical quality. Like any subatomic particles, neutrons can be thought of as waves as well as particles. When they bombard matter, their wave nature comes into play. The slow neutrons from the ANS will have a wavelength about equal to the spacing between atoms in a typical solid, making the neutrons especially sensitive to atom-by-atom architecture

    Environmental restoration (ER) is the process of removing a facility from service, the demolition of structures the identification and disposal of all hazardous and radioactive wastes, the decontamination of equipment and materials, and the restoration of a site for unrestricted use. The number of ER projects encompassing hazardous, industrial, and radiological conditions is expected to increase in response to various program requirements or mission changes. As a result, the practicing health physicist (HP) may have to address unique health and safety (H and S) issues beyond those of performing routine radiological activities. These unique H and S issues could include, but are not limited to the razing of buildings, the removal of radioactive materials and hazardous chemicals, below-grade excavation, confined space entry, storing flammable or combustible liquids, monitoring exposure to hazardous substances, contacting energized systems (e.g., electricity, hydraulics), noise abatement, the nullification of manufacturer warranties, and the operation and movement of heavy equipment. The purpose of this paper is to educate the practicing HP about these issues by reviewing specific regulations governing all H and S activities, and to provide an example of a site-specific H and S primer (e.g., Health and Safety Plan [HASP]). This primer advices the practicing HP about sound H and S principles, furnishes basic strategies for performing a hazard assessment/job safety analysis (HA/JSA) that can be applied to any ER project, and describes various engineering and administrative controls to mitigate hazardous exposures to ER personnel. In addition, 26 inspection checklist topics are available from the primary author to evaluate the adequacy of the engineering and administrative controls, or to necessitate the use of personal protective equipment (PPE) thereby mitigating the corresponding hazard.

    Medical physicists face numerous challenges that create stress in the professional workplace. The modern work environment contains multiple communications channels, such as email, smart phones, text and instant messaging, voice mail, pagers, and more. These media make it difficult to organize incoming information, set priorities, and move important work forward in the face of rapid change and the requirement to fulfill multiple responsibilities. Medical physicists in particular are likely to feel acute stress due to off-peak work hour requirements, varied responsibilities including clinical duties, research, teaching, and regulatory matters, and the complexity of supervising other staff members. Many medical physicists also work in multiple physical locations, adding complexity to the task of organizing information and resources. Another common difficulty is that medical physicists' responsibilities typically include some duties that render them subject to frequent and urgent interruption, such as emergency response coverage for radiation safety. The real challenges in the current medical physics work environment differ from those encountered while taking courses and conducting research, as well as from earlier periods when medical physicists faced fewer varied responsibilities, slower-paced change, or both. Today's practicing physicist can benefit greatly from developing a formal framework and skill set to manage their personal workflow. This greatly increases the individual's effectiveness and reduces feelings of stress, while improving the effectiveness of teams or groups in which they participate. In this session, participants will learn about a number of techniques and strategies to manage their own personal workflow. Examples familiar to the medical physicist will be provided to illustrate methods to capture, organize, and act on important information, to delegate effectively, and to handle inevitable interruptions. 1. Describe the use of a personal workflow

    2010-04-12

    Significant controversy surrounds the 2012 / 2014 decision announced by the Trustees of the American Board of Radiology (ABR) in October of 2007. According to the ABR, only medical physicists who are graduates of a Commission on Accreditation of Medical Physics Education Programs, Inc. (CAMPEP) accredited academic or residency program will be admitted for examination in the years 2012 and 2013. Only graduates of a CAMPEP accredited residency program will be admitted for examination beginning in the year 2014. An essential question facing the radiation oncology physics community is an estimation of supply and demand for medical physicists through the year 2020. To that end, a Demand & Supply dynamic model was created using STELLA software. Inputs into the model include: a) projected new cancer incidence and prevalence 1990-2020; b) AAPM member ages and retirement projections 1990-2020; c) number of ABR physics diplomates 1990-2009; d) number of patients per Qualified Medical Physicist from Abt Reports I (1995), II (2002) and III (2008); e) non-CAMPEP physicists trained 1990-2009 and projected through 2014; f) CAMPEP physicists trained 1993-2008 and projected through 2014; and g) working Qualified Medical Physicists in radiation oncology in the United States (1990-2007). The model indicates that the number of qualified medical physicists working in radiation oncology required to meet demand in 2020 will be 150-175 per year. Because there is some elasticity in the workforce, a portion of the work effort might be assumed by practicing medical physicists. However, the minimum number of new radiation oncology physicists (ROPs) required for the health of the profession is estimated to be 125 per year in 2020. The radiation oncology physics community should plan to build residency programs to support these numbers for the future of the profession.

    Many medical physicists are scientists at heart and their career fulfillment includes a balance of clinical service and research development. Multidisciplinary collaboration is a great way for the medical physicists to advance science and technology of our fields and the fields of our collaborators. Cross-pollination among scientists of different fields has been the key for some of the most significant breakthroughs in science and medicine and produced some of the most rewarding experiences for the individuals involved. However, medical physicists face unique challenges in establishing multidisciplinary collaboration because our time and resources for research are often quite limited compared to basic scientists. Yet we medical physicists are uniquely positioned and have a tremendous opportunity to create/contribute to multidisciplinary research: our fields are already multidisciplinary in nature and hospital environment is problem rich. How do we establish and carry out research collaboration with scientists of other fields? How to balance research with your higher priority clinical service? How do you find the right multidisciplinary collaboration in your own environment? We will discuss the challenges, provide real exemplary solutions to the above questions, and offer advise to medical physicists who are interested in starting or improving their multidisciplinary collaboration. There are different kinds of multidisciplinary collaborations a medical physicist can create and participate at different involvement levels. Multidisciplinary collaboration is not for every medical physicist but for those who seek and devote time to it, the experience can be truly rewarding and the impact can be enormous. 1. Learn the types of multidisciplinary collaboration medical physicists can created/participated 2. Learn the approaches and strategies to develop collaborations with scientists and professional of other fields3. Understand the challenges and different approaches to

    This publication addresses the shortfall of well trained and clinically qualified medical physicists working in radiation medicine. The roles, responsibilities and clinical training requirements of medical physicists have not always been well defined or well understood by health care professionals, health authorities and regulatory agencies. To fill this gap, this publication provides recommendations for the academic education and clinical training of clinically qualified medical physicists, including recommendations for their accreditation certification and registration, along with continuous professional development. The goal is to establish criteria that support the harmonization of education and clinical training worldwide

  19. The Many Worlds of Leo Szilard: Physicist, Peacemaker, Provocateur

    2014-03-01

    Best known for being the first to conceive and patent the nuclear chain reaction in the 1930s, Leo Szilard should also be remembered for other insights in both physics and biology, and for historical initiatives to control the A-bomb he helped create. In physics, Szilard applied entropy to data in a seminal 1929 paper that laid the basis for ``information theory.'' Szilard co-designed an electromagnetic refrigerator pump with Einstein in the 1920s, in 1939 he co-designed the first nuclear reactor with Enrico Fermi, and he later thought up and named the nuclear ``breeder'' reactor. Biologist Francois Jacob called Szilard an ``intellectual bumblebee'' for the many novel ideas he shared, including one that earned Jacob and others the Nobel Prize. James D. Watson said that for intellectual stimulation he liked being around Szilard because ``Leo got excited about something before it was true.'' A political activist, Szilard proposed and drafted the 1939 letter Einstein sent to President Franklin Roosevelt that warned of German A-bomb work and led to the Manhattan Project - where Szilard was ``Chief Physicist.'' Yet Szilard then worked tirelessly to curb nuclear weapons, organizing a scientists' petition to President Truman and lobbying Congress for civilian control of the atom. Szilard loved dreaming up new institutions. He helped to create the Pugwash Conferences on Science and World Affairs, and founded the Council for a Livable World - the first political action committee for arms control. In biology, Szilard proposed the European Molecular Biology Organization modeled on CERN, and helped create the Salk Institute for Biological Studies, where he was one of the first fellows. Shy, witty, and eccentric, Szilard wrote a political satire in 1960 that predicted when the US-Soviet nuclear arms race would end in the late 1980s. Another satire, ``My Trial as a War Criminal'' about scientists' responsibilities for weapons of mass destruction, is credited with prompting

    Some research indicates that women professionals-when compared to men-may be more ethical in the workplace. Existing literature that discusses gender and ethics is confined to the for-profit business sector and primarily to a US context. In particular, there is little attention paid to gender and ethics in science professions in a global context. This represents a significant gap, as science is a rapidly growing and global professional sector, as well as one with ethically ambiguous areas. Adopting an international comparative perspective, this paper relies on 121 semi-structured interviews with US and UK academic physicists to examine how physicists perceive the impact of gender on science ethics. Findings indicate that some US and UK physicists believe that female scientists handle ethical issues within science in a feminine way whereas their male colleagues approach ethics in a masculine way. Some of these physicists further claim that these different approaches to science ethics lead to male and female scientists' different levels of competitiveness in academic physics. In both the US and the UK, there are "gender-blind" physicists, who do not think gender is related to professional ethics. Relying on physicists' nuanced descriptions this paper contributes to the current understanding of gender and science and engineering ethics.

  5. Seeing Things: Image and Affect

    Full Text Available In the age of digital media how might we speak about images of torture, and how might we regard the pain of others?  Using the examples of a short film by Alejandra Canales which recounts the experience of torture, and the Abu Ghraib photographs, this article seeks to repose the question of the function of the image and its relationship to epistemology. How do we know what we see? And how might we rethink the orthodox function of the image in the age of digital technology? In attempting to answer these questions, I argue that the production of virtual experience is a capacity of the human body, and that image making, like all genres of communication, is a practice in virtual community.

    Achieving a clear view of one’s personality is a challenging but crucial developmental task during adolescence, which has enduring influences. This task might be harder if significant others see individuals differently from how the adolescents see themselves. Supporting this, the looking-glass-self theory suggests that significant others constitute a social mirror into which the individual gazes to form his/her self-view. The present study was the first to longitudinally examine whether self–other agreement in personality during adolescence (i.e., self–parent and self–friend agreement at age 12 and self–mother and self–father agreement at age 17) promote self-esteem development from age 17 to 29 years (N =186, 53% boys). Results for girls consistently confirmed the hypothesized beneficial effect of self–parent agreement, while the picture was more complicated for boys. That is, for girls, self–parent agreement at age 12 and age 17 both predicted steeper increases in self-esteem. For boys, steeper self-esteem development was predicted by higher self–parent agreement at age 12, but unexpectedly, also by lower self–parent agreement at age 17. All these results remained after controlling for (self-rated) personality. Moreover, self–friend agreement did not show any effects on self-esteem development, suggesting that the influence of peers’ convergence with self-views during early adolescence may not be as prominent as parents’. Results are discussed from the perspective of self-view formation and maintenance during adolescence and young adulthood. The present study sheds light on the longitudinal effect of one’s own view of personality being shared by important others on self-esteem development. PMID:29276319

    [Correction Notice: An Erratum for this article was reported in Vol 101(5) of Journal of Applied Psychology (see record 2016-21000-001). In the article, Table 2 contained a production-related formatting error. Values from column 11 onward were shifted upwards in the table. All versions of this article have been corrected.] Despite an increased interest in the phenomenon of stigma in organizations, we know very little about the interactions between those who are stigmatized and those who stigmatize them. Integrating both the perceptions of the stigmatized worker and the stigmatizing customer into one model, the present study addresses this gap. It examines the role of stereotypes held by customers of stigmatized organizations and metastereotypes held by the stigmatized workers themselves (i.e., their shared beliefs of the stereotypes customers associate with them) in frontline exchanges. To do so, data regarding frontline workers (vendors) of homeless-advocate newspapers from 3 different sources (vendors, customers, trained observers) were gathered. Multilevel path-analytic hypotheses tests reveal (a) how frontline workers' prototypicality for a stigmatized organization renders salient a stigma within frontline interactions and (b) how stereotypes by customers and metastereotypes by frontline workers interact with each other in such contacts. The results support a hypothesized interaction between frontline workers' metastereotypes and customers' stereotypes-what we call the "stigma magnification effect". The study also derives important practical implications by linking stigma to frontline workers' discretionary financial gains. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    The promotion plan for the Platform of Human Resource Development for Cancer (Ganpro) was initiated by the Ministry of Education, Culture, Sports, Science and Technology of Japan in 2007, establishing a curriculum for medical physicists. In this study, we surveyed the educational outcomes of the medical physicist program over the past 10 years since the initiation of Ganpro. The Japan Society of Medical Physics mailing list was used to announce this survey. The questionnaire was created by members of the Japanese Board for Medical Physicist Qualification, and was intended for the collection of information regarding the characteristics and career paths of medical physics students. Students who participated in the medical physics program from 2007 to 2016 were enrolled. Thirty-one universities (17 accredited and 14 non-accredited) were represented in the survey. In total, 491, 105 and 6 students were enrolled in the Master's, Doctorate and Residency programs, respectively. Most students held a Bachelor's degree in radiological technology (Master's program, 87%; Doctorate program, 72%). A large number of students with a Master's degree worked as radiological technologists (67%), whereas only 9% (n = 32) worked as medical physicists. In contrast, 53% (n = 28) of the students with a Doctorate degree worked as medical physicists. In total, 602 students (from 31 universities) completed the survey. Overall, although the number of the graduates who worked as medical physicists was small, this number increased annually. It thus seems that medical institutions in Japan are recognizing the necessity of licensed medical physicists in the radiotherapy community.

  9. Clinical Training of Medical Physicists Specializing in Nuclear Medicine (Spanish Edition)

    International Nuclear Information System (INIS)

    2013-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists who are based in a clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement for Research, Development and Training related to Nuclear Science and Technology (RCA) for the Asia-Pacific region. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in this region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in nuclear medicine was started in 2009 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experience of clinical training in Australia, Croatia and Sweden and was moderated by physicists working in the Asian region. The present publication follows the approach of earlier IAEA publications in the Training Course Series, specifically Nos 37 and 47, Clinical Training of Medical Physicists Specializing in Radiation Oncology and Clinical Training of Medical Physicists

    Full Text Available Mario Bunge was born in Argentina in the final year of the First World War. He learnt atomic physics andquantum mechanics from an Austrian refugee who had been a student of Heisenberg. Additionally he taughthimself modern philosophy in an environment that was a philosophical backwater. He was the first SouthAmerican philosopher of science to be trained in science. His publications in physics, philosophy, psychology,sociology and the foundations of biology, are staggering in number, and include a massive 8-volume Treatise onPhilosophy. The unifying thread of his scholarship is the constant and vigorous advancement of theEnlightenment Project, and criticism of cultural and academic movements that deny or devalue the core planksof the project: namely its naturalism, the search for truth, the universality of science, rationality, and respect forindividuals. At a time when specialisation is widely decried, and its deleterious effects on science, philosophy ofscience, educational research and science teaching are recognised – it is salutary to see the fruits of one person’spursuit of the ‘Big’ scientific and philosophical picture.

  12. Process tomography: Seeing is believing

    As the chemical process industries try new ways to optimize their processes, they are taking a closer look at tomography. Already well established in medical diagnostics, the technique has found some CPI applications but has long been considered too expensive and impractical for routine use. Promising to change this perception are recent developments in tomographic sensors, image processing algorithms, as well as data processing. Of particular interest to the CPI is tomography's ability t provide real-time cross sectional images of conditions inside process equipment, allowing operators to see what's going on in such opaque regions as packed catalyst beds, multiphase solutions, powder mixers, and fluidized beds. The images contain a wealth of data that can be used to: design equipment, verify simulation models and calculations derived via computational fluid dynamics, monitor fluid flow and environmental conditions, and image velocity profiles. One interesting application is as a way of inspecting radioactive waste drums to decide where they should be sent for permanent storage. Another use being studied is the monitoring of air sparging of contaminated areas

    Full Text Available If we recall the most important words for the poetry, we should begin the story with the stones, lily, hands and blood, which, if you look at them with the philological accuracy, are interrelated: situate themselves clearly on opposite banks of the creative process. They talk about the construction of the building consisting of perceptions about their own strength and weakness, ecstasy and congealing in what for centuries the classics poets have tried to fathom: the harmony and clarity, driven by the hope that in life they should above all stick to be beauty. And in addition, they ought to go further than discipline, practice eye and expand the field of view, should not shun from the gusts of the heart, because the heart grows more powerful due to great ideas, passions. Spacious becomes the vision of writing, it is the weave of contradictions - this is how one of the most important twentieth-century poets, who wrote in Yiddish, Anna Margolin sees it. Margolin’s poetry is a clear return towards neoclassicism, building up topics, theses, allusions, ideas taken from ideologically close to her artists of great individuality, Anna Akhmatova (from whom she took her name, Osip Mandelstam, Rainer Maria Rilke, Ezra Pound.

  14. The second physicist on the history of theoretical physics in germany

    CERN Document Server

    Jungnickel, Christa

    2017-01-01

    This book explores the rise of theoretical physics in 19th century Germany. The authors show how the junior second physicist in German universities over time became the theoretical physicist, of equal standing to the experimental physicist. Gustav Kirchhoff, Hermann von Helmholtz, and Max Planck are among the great German theoretical physicists whose work and career are examined in this book. Physics was then the only natural science in which theoretical work developed into a major teaching and research specialty in its own right. Readers will discover how German physicists arrived at a well-defined field of theoretical physics with well understood and generally accepted goals and needs. The authors explain the nature of the work of theoretical physics with many examples, taking care always to locate the research within the workplace. The book is a revised and shortened version of Intellectual Mastery of Nature: Theoretical Physics from Ohm to Einstein, a two-volume work by the same authors. This new edition ...

    A comprehensive Code of Ethics for the members of the American Association of Physicists in Medicine (AAPM) is presented as the report of Task Group 109 which consolidates previous AAPM ethics policies into a unified document. The membership of the AAPM is increasingly diverse. Prior existing AAPM ethics polices were applicable specifically to medical physicists, and did not encompass other types of members such as health physicists, regulators, corporate affiliates, physicians, scientists, engineers, those in training, or other health care professionals. Prior AAPM ethics policies did not specifically address research, education, or business ethics. The Ethics Guidelines of this new Code of Ethics have four major sections: professional conduct, research ethics, education ethics, and business ethics. Some elements of each major section may be duplicated in other sections, so that readers interested in a particular aspect of the code do not need to read the entire document for all relevant information. The prior Complaint Procedure has also been incorporated into this Code of Ethics. This Code of Ethics (PP 24-A) replaces the following AAPM policies: Ethical Guidelines for Vacating a Position (PP 4-B); Ethical Guidelines for Reviewing the Work of Another Physicist (PP 5-C); Guidelines for Ethical Practice for Medical Physicists (PP 8-D); and Ethics Complaint Procedure (PP 21-A). The AAPM Board of Directors approved this Code or Ethics on July 31, 2008.

  16. History and development of medical physics and medical physicist in Japan

    2014-01-01

    The history of medical physics in Japan dates back to the mid-1950's when radioisotope sources such as cobalt-60 were initiated into hospitals. In 1961, a total of about 30 medical physics researchers created a sub-committee of medical physics under the Japan Radiological Society (JRS), which flourished throughout the decade, and the number of members exceeded to more than 200 in 1970. Although there were great advances in medical technologies, the number of members of the medical physics community did not grow for the next two decades from 1980 to 2000. Then, the JRS began to officially recognize medical physicists as a professional group in 1987. Qualifications of candidacy for the examination included having the education equivalent of a Bachelor of Science/Engineering and being a member of the JRS. For the first official examination, 70 medical physicists were approved by the JRS. As of 2013, there are currently 700 medical physicists, however, the number of practicing clinical medical physicists remains only about 150. The main reason for this limited number of medical physicists is that the certification is not recognized as a national license and therefore is challenging to find professional employment as qualified medical personnel at hospitals.

    The transverse momentum distributions of the strange and double-strange hyperon resonances ([Formula: see text], [Formula: see text]) produced in p-Pb collisions at [Formula: see text] TeV were measured in the rapidity range [Formula: see text] for event classes corresponding to different charged-particle multiplicity densities, [Formula: see text]d[Formula: see text]/d[Formula: see text]. The mean transverse momentum values are presented as a function of [Formula: see text]d[Formula: see text]/d[Formula: see text], as well as a function of the particle masses and compared with previous results on hyperon production. The integrated yield ratios of excited to ground-state hyperons are constant as a function of [Formula: see text]d[Formula: see text]/d[Formula: see text]. The equivalent ratios to pions exhibit an increase with [Formula: see text]d[Formula: see text]/d[Formula: see text], depending on their strangeness content.

    The lifetime of the [Formula: see text] meson is measured using semileptonic decays having a [Formula: see text] meson and a muon in the final state. The data, corresponding to an integrated luminosity of [Formula: see text], are collected by the LHCb detector in [Formula: see text] collisions at a centre-of-mass energy of 8 TeV. The measured lifetime is [Formula: see text]where the first uncertainty is statistical and the second is systematic.

  19. The Mental Aftermath - The Mentality of German Physicists 1945-1949

    Few scientific communities have been more thoroughly studied than 20th-century German physicists. Yet their behavior and patterns of thinking immediately after the war remains puzzling. During the first five postwar years they suspended their internecine battles and a strange solidarity emerged. Former enemies were suddenly willing to exonerate each other blindly and even morally upright physicists began to write tirades against the 'denazification mischief' or the 'export of scientists'. Personal idiosyncracies melded into a strangely uniform pattern of rejection or resistance to the Allied occupiers, with attendant repressed feelings and self-pity. Politics was once again perceived as remote, dirty business. It was feared that the least concession of guilt would bring down even more severe sanctions on their discipline. Using tools from the history of mentality, such as analysis of serial publications, these tendenciesare examined. The perspective of emigre physicists, as reflected in their private letters and reports, embellish this portrait.

    It is vitally important that medical physicists understand the clinical questions that radiologists are trying to answer with patient images. Knowledge of the types of information the radiologist needs helps medical physicists configure imaging protocols that appropriately balance radiation dose, time, and image quality. The ability to communicate with radiologists and understand medical terminology, anatomy, and physiology is key to creating such imaging protocols. In this session, radiologists will present clinical cases and describe the information they are seeking in the clinical images. Medical physicists will then discuss how imaging protocols are configured. Learning Objectives: Understand the types of information that radiologists seek in medical images. Apply this understanding in configuring the imaging equipment to deliver this information. Develop strategies for working with physician colleagues.

    A questionnaire survey of medical physicists and quality managers for radiation therapy was performed by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) Future Planning Committee. We mailed the questionnaire to 726 radiotherapy facilities with the answers returned from 353 radiotherapy facilities. The result showed 178 facilities were staffed by radiotherapy workers who were licensed medical physicists or quality managers. A staff of 289 was licensed radiotherapy workers. Most of the staff were radiotherapy technologists. Quality control for radiation therapy was rated satisfactory according to each facility's assessment. Radiation therapy of high quality requires continued education of medical physicists and quality managers, in addition to keeping up with times for quality control. (author)

    2014-01-01

    Tuesday 25 March 2014 at 4 p.m. in the Library, bldg. 52-1-052 "Differential manifolds: a basic approach for experimental physicists" by Paul Baillon,  World Scientific, 2013, ISBN 978-981-4449-56-4. Differential manifold is the framework of particle physics and astrophysics nowadays. It is important for all research physicists to be accustomed to it, and even experimental physicists should be able to manipulate equations and expressions in this framework. This book gives a comprehensive description of the basics of differential manifold with a full proof of elements. A large part of the book is devoted to the basic mathematical concepts, which are all necessary for the development of the differential manifold. This book is self-consistent; it starts from first principles. The mathematical framework is the set theory with its axioms and its formal logic. No special knowledge is needed. Coffee will be served from 3.30 p.m.

    In the current rapidly changing Healthcare environment, many groups are competing for limited resources. How can medical physicists position themselves to be a relevant stakeholder in the discussion of how those resources are allocated Our value goes beyond what can be shown in a business plan and is heavily involved with safety and quality. Three areas will be explored: What is our value? Who needs to receive that message? How do we communicate that message? To help frame the discussion in terms of how other stakeholders may view the value of medical physicists, a physician and an administrator will present their perspective. Lastly, a multidisciplinary panel will present real life examples of strategies that can be utilized today to establish the value of medical physicists. The presentation of these examples will lead into an interactive question and answer time. V. Willcut, I work for Elekta. There was no research associated with this talk.

    This paper reports on a survey of medical physicists who write and use in-house written software as part of their professional work. The goal of the survey was to assess the extent of in-house software usage and the desire or need for related software quality guidelines. The survey contained eight multiple-choice questions, a ranking question, and seven free text questions. The survey was sent to medical physicists associated with cancer centers across Canada. The respondents to the survey expressed interest in having guidelines to help them in their software-related work, but also demonstrated extensive skills in the area of testing, safety, and communication. These existing skills form a basis for medical physicists to establish a set of software quality guidelines.

    Physicists have had a special interest in American national security and arms control since at least the Manhattan Project. They have served our country in uniform and in the career civil service. Some have left academic careers for brief periods to work as political appointees, consultants, or resident scholars and then returned to an academic life, but often with changed goals. Some have tried government life and left nearly immediately, while others dipped a toe in and decided to stay. I will look at real-life examples, mostly using real names, drawn from my career and circle of colleagues to try to explain why some physicists have been extremely successful, why others have not, and what happens to a physicist who moved to Washington and decides to stay. I will also discuss routes into public service for those interesting in giving it a try.

  9. Modern Differential Geometry For Physicists. 2nd Edn

    2006-01-01

    Most of us sometimes have to face a student asking: 'What do I need to get started on this'. (In my case 'this' would typically be a topic in general relativity.) After thinking about it for quite a while, and consulting candidate texts again and again, a few days later I usually end up saying: read this chapter in book I (but without going too much detail), then that chapter in book II (but ignore all those comments), then the first few sections of this review paper (but do not try to work out equations NN to NNN), and then come back to see me. In the unlikely event that the student comes back without changing the topic, there follows quite a bit of explaining on a blackboard over the following weeks. From now on I will say: get acquainted with the material covered by this book. As far as Isham's book is concerned, 'this' in the student's question above can stand for any topic in theoretical physics which touches upon differential geometry (and I can only think of very few which do not). Said plainly: this book contains most of the introductory material necessary to get started in general relativity, or those branches of mathematical physics which require differential geometry. A student who has mastered the notions presented in the book will have a solid basis to continue into specialized topics. I am not aware of any other book which would be as useful as this one in terms of the spectrum of topics covered, stopping at the right place to get sufficient introductory insight. According to the publisher, these lecture notes are the content of an introductory course on differential geometry which is taken by first-year theoretical physics PhD students, or by students attending the one-year MSc course 'Quantum Fields and Fundamental Forces' at Imperial College, London. The volume is divided into six chapters: - An Introduction to Topology; - Differential Manifolds; - Vector Fields and n-Forms; - Lie Groups; - Fibre Bundles; - Connections in a Bundle. It is a sad

    2012-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology.

    The great discoveries and applications of nuclear science have had tremendous impact on the progress and development of mankind over the last 100 years. In the 1920's to 1940's, many young Chinese who yearned to save the country through science and education went to west Europe and north America to study science, including physics. Studying and working with famous physicists throughout the world, they made many important contributions and discoveries in the development of nuclear science. This paper describes the historical contributions of the older generation of Chinese physicists to nuclear science

    designed the platework of ships and bridges, we see the upper elastic layer of the Earth bending under the loads applied by mountains and ice sheets: about 11 000 years ago, a 2 km load of ice melted, and Scandinavia and northern Canada are still springing back into shape at about 10 mm per year. About 100 million years ago, the plate supporting North America and Europe fractured, and we can measure their continuing separation with lasers and microwaves at a few cm per year. We are now just able to make acoustic images of turbulent plumes churning up the Earth's deep interior as heat from radioactive decay is converted into the motion of convective overturn: the Earth is a heat engine! So how is all this `knowledge' possible when there are absolutely no direct observations of the interior of the Earth or its remote past? Over the course of the last few centuries, careful laboratory observations have identified patterns in the way natural materials behave which we now codify as the laws of physics. They enable us to construct a model of how materials would behave under more exotic conditions and at past and future times. As one example, we measure the rate at which radioactive atoms decay and identify that the half-life of a particular species is a `constant of nature', that is, we have so far found no ambient conditions that cause it to vary. With this experience, we measure radioactive isotopes in a rock to find the proportion of parent atoms remaining to the daughter atoms produced by its decay. Knowing the half-life makes the rock a natural clock with which to date an event in the remote past. In the special feature on Geophysics in this issue, we have picked just a few examples to show how basic physics - gravity, electricity, magnetism and sound - can be harnessed to investigate what we can never observe directly. `Antarctic seismology' is an example of the Earth being doubly remote: its surface as well as its interior are inaccessible. Here, practical fieldwork

    2006-01-01

    Full text: Medical radiology and especially the radiotherapy is the birthplace of modern medical physics. Medical physicists have proven place and important role in research and practice in radiotherapy. They share the responsibility with physicians in varied daily work in this medical speciality. The rapid development of medical imaging in last decades increases the need of competence of medical physicists. Quality assurance in Diagnostic Radiology aimed to achieve maximum diagnostic information at minimal risk and with minimal prize, which is obligatory for the members of the EU, is impossible to be implemented without medical physicists. The enforced recently Ordinance 30/2005 of the Ministry of Health forms the regulatory basis of obligatory implementation of Quality Assurance at medical use of ionizing radiation in the country. This Ordinance introduces the requirements of the EURATOM 97/43 Directive on health protection of individuals against the dangers of ionizing radiation in relation to medical exposure. It regulates also the responsibilities of medical physicists in radiology. Forthcoming is the practical implementation of these requirements, which needs the competence and efforts of Medical physics community as well as of radiologists in the country

    2016-01-01

    It was at the height of the Cold War, in the summer of 1950, when Bruno Pontecorvo mysteriously vanished behind the Iron Curtain. Who was he, and what caused him to disappear? Was he simply a physicist, or also a spy and communist radical? A protege of Enrico Fermi, Pontecorvo was one of the most promising nuclear physicists in the world. He spent years hunting for the Higgs boson of his day - the neutrino - a nearly massless particle thought to be essential to the process of particle decay. His work on the Manhattan Project helped to usher in the nuclear age, and confirmed his reputation as a brilliant physicist. Why, then, would he disappear as he stood on the cusp of true greatness, perhaps even the Nobel Prize? In this book, physicist and historian Frank Close offers a heretofore untold history of Pontecorvo's life, based on unprecedented access to Pontecorvo's friends and family and the Russian scientists with whom he would later work. Close takes a microscope to Pontecorvo's life, combining a thorough biography of one of the most important scientists of the twentieth century with the drama of Cold War espionage. With all the elements of a Cold War thriller - classified atomic research, an infamous double agent, a possible kidnapping by Soviet operatives - this book is a history of nuclear physics at perhaps its most powerful: when it created the bomb

    2014-01-01

    Full Text Available In the arena of radiation oncology special procedures, medical physicists are often the focus professionals for implementation and administration of advanced and complex technologies. One of the most vexing and challenging aspects of managing complexity concerns the ongoing internal qualification and credentialing of radiation oncology physicists to perform patient special procedures. To demonstrate ongoing qualification, a physicist must a document initial training and successful completion of competencies to implement and perform this procedure, b demonstrate familiarity with all aspects of the commissioning and quality assurance process, c demonstrate continuing education respecting this procedure, d demonstrate the peer-reviewed completion of a minimum number of patient special procedures during a specified time span, and e demonstrate satisfactory overall progress toward maintenance of specialty board certification. In many respects, this information complement is similar to that required by an accredited residency program in therapy physics. In this investigation, we report on the design of a management tool to qualify staff radiation oncology physicists to deliver patient procedures.

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for radiation therapy. There is a general and growing awareness that radiation medicine is increasingly dependant on well trained medical physicists that are based in the clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognised by the members of the Regional Cooperative Agreement (RCA) for research, development and training related to nuclear sciences for Asia and the Pacific. Consequently a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in radiation therapy was started in 2005 with the appointment of a core drafting committee of regional and international experts. Since 2005 the IAEA has convened two additional consultant group meetings including additional experts to prepare the present publication. The publication drew heavily, particularly in the initial stages, from the experience and documents of the Clinical Training Programme for Radiation Oncology Medical Physicists as developed by the Australasian College of Physical Scientists and Engineers in Medicine.

    2013-03-01

    American physicists faced many challenges in the 1970s: declining research budgets; public skepticism of scientific authority; declining student enrollments; and pressure to shift to topics such as biomedicine, environmental remediation, alternative energy, public housing and transport, and disability technologies. This paper examines the responses to these challenges of a small group of Santa Barbara physicists. While this group is not representative of the American physics profession, the success and failure of their responses to changed conditions tells us something about how American physicists got through the 1970s, and about the origins of some features of American physics today. The three physicists examined here are Philip Wyatt, David Phillips, and Virgil Elings. In the late `60s, Wyatt left a defense think tank to found an instrumentation firm. The Santa Barbara oil spill and other factors pushed that firm toward civilian markets in biomedicine and pollution measurement. Phillips joined Wyatt's firm from UCSB, while also founding his own company, largely to sell electronic devices for parapsychology. Phillips was also the junior partner in a master's of scientific instrumentation degree curriculum founded by Elings in order to save UCSB Physics' graduate program. Through the MSI program, Elings moved into biomedical research and became a serial entrepreneur. By the 1990s, Wyatt, Phillips, and Elings' turn toward academic entrepreneurship, dual military-civilian markets for physics start-ups, and interdisciplinary collaborations between physicists and life scientists were no longer unusual. Together, their journey through the `70s shows how varied the physics' profession's response to crisis was, and how much it pivoted on new interactions between university and industry.

    2015-07-01

    Full Text Available According to Rorty, Davidson and Brandom, to have an experience is to be caused by our senses to hold a perceptual belief. This article argues that the phenomenon of seeing-as cannot be explained by such a conception of perceptual experience. First, the notion of experience defended by the aforementioned authors is reconstructed. Second, the main features of what Wittgenstein called “seeing aspects” are briefly presented. Finally, several arguments are developed in order to support the main thesis of the article: seeing-as cannot be explained by the conception of experience defended by Rorty, Davidson and Brandom.

    This report describes the history of computer graphics and Picasso at the Halden Project and how Picasso has been used at HRP, in HRP member organisations and in other organisations. It motivates the change of name from Picasso to ProcSee based on plans to extend the use of the product and to avoid a potential conflict regarding the name. It describes features introduced during the last years to motivate users to utilise new functionality, describes how tests shows that ProcSee has unique capabilities when it comes to performance for handling frequent display updates for large complex displays, and describes new planned features to be implemented in ProcSee. The report concludes that Picasso/ProcSee has been and will continue to be of vital importance for the HRP research programme within the fields of human-machine interface design and human-machine interaction.

    It is pointed out that despite recent advances in the use of spacecraft as observatory platforms, much astronomy is still conducted from the surface of the earth. The literature on astronomical seeing and observatory site selection is widely scattered throughout journals and conference reports concerned with various disciplines. This survey has the objective to represent the state of the subject up to 1982. A description of the history and prospects of the considered subject is presented, and the optics of seeing are examined. The meteorology of seeing is discussed, taking into account aspects of micrometeorology and small-scale turbulence near the surface, the diurnal cycle in the planetary boundary layer, the temperature structure above the planetary boundary layer, and the effects of terrain. Attention is given to the calculation of system performance from microthermal data, optical methods for the measurement of seeing, and techniques for minimizing image-degrading effects of the atmosphere. 279 references

    The production of the strange and double-strange baryon resonances ([Formula: see text], [Formula: see text]) has been measured at mid-rapidity ([Formula: see text][Formula: see text]) in proton-proton collisions at [Formula: see text] [Formula: see text] 7 TeV with the ALICE detector at the LHC. Transverse momentum spectra for inelastic collisions are compared to QCD-inspired models, which in general underpredict the data. A search for the [Formula: see text] pentaquark, decaying in the [Formula: see text] channel, has been carried out but no evidence is seen.

    Distance measures play a central role in evolving the clustering technique. Due to the rich mathematical background and natural implementation of [Formula: see text] distance measures, researchers were motivated to use them in almost every clustering process. Beside [Formula: see text] distance measures, there exist several distance measures. Sargent introduced a special type of distance measures [Formula: see text] and [Formula: see text] which is closely related to [Formula: see text]. In this paper, we generalized the Sargent sequence spaces through introduction of [Formula: see text] and [Formula: see text] sequence spaces. Moreover, it is shown that both spaces are BK -spaces, and one is a dual of another. Further, we have clustered the two-moon dataset by using an induced [Formula: see text]-distance measure (induced by the Sargent sequence space [Formula: see text]) in the k-means clustering algorithm. The clustering result established the efficacy of replacing the Euclidean distance measure by the [Formula: see text]-distance measure in the k-means algorithm.

  18. A half-life the divided life of Bruno Pontecorvo, physicist or spy

    2015-01-01

    Bruno Pontecorvo dedicated his career to hunting for the Higgs boson of his day: the neutrino, a nearly massless particle considered essential to the process of nuclear fission. His work on the Manhattan project under Enrico Fermi confirmed his reputation as a brilliant physicist and helped usher in the nuclear age. He should have won a Nobel Prize, but late in the summer of 1950 he vanished. At the height of the Cold War, Pontecorvo had disappeared behind the Iron Curtain. In Half-Life, physicist and historian Frank Close offers a heretofore untold history of Pontecorvo’s life, based on unprecedented access to his friends, family, and colleagues. With all the elements of a Cold War thriller—classified atomic research, an infamous double agent, a kidnapping by Soviet operatives—Half-Life is a history of particle physics at perhaps its most powerful: when it created the bomb.

    Medical physicists can play a role in education of future radiologists and technologists by teaching quality control needs and techniques. He or she can also provide service to the diagnostic section by establishing a quality control program. Finally, the medical physicist can play an important role in the development of simple and inexpensive techniques for quality control by radiological technologists. The ongoing work at the University of Wisconsin in this area is to provide quality control in measurement of the effective kVcp, the measurement of the effective focal spot size, the performance of the processing equipment, the output in mR/mAs, and the measurement of the half-value-layer and the total filtration.

    Specialized Education of Czech radiological physicists in diagnostic radiology (DR), nuclear medicine (NM) or radiotherapy (RT) follows-up to regulated university master program. A form and content of Specialized Education which will be defined by General Programs must therefore reflect previous step. Graduates from Specialized Education will be fully competent clinical radiological physicists for DR, NM or RT according to their branch. Therefore, we strongly recommend that General Programs are made very carefully reflecting requirements of Specialized Education and current status of the field in the Czech Republic. Currently, CAMP works on its own version of General Program for each branch. CAMP is ready to collaborate closely with all other bodies included in preparation of General Programs and with the Czech Ministry of Health. (authors)

    Recently Russia has been affected by the global financial crisis, which has had both positive and negative effects on women physicists. The feminization of science and the stratification that characterize the Russian scientific community in general also affect the field of physics. This paper discusses the proportion of women in leadership and managerial positions in different areas of science and education and highlights the differences between women and men in their careers in physics and defense of their theses. Lomonosov Moscow State University is used to demonstrate the dynamics of gender in different academic positions. The professional activity of young women physicists is illustrated by their participation in all-Russian scientific forums, demonstrating their commitment to remain active in their careers despite the challenges of the current economic conditions.

  4. The radioactivity, the sun, the Earth and Kelvin's death. A difficult dialog between physicists and geologists

    The question of the age of the Earth has remained mythical for a long time. During the last quarter of the 19. century, this question was the center of a strong controversy initiated by a physicist, William Thomson, the future Lord Kelvin. During the beginning of the 20. century, the discoveries of Becquerel and Pierre and Marie Curie about radioactivity gave rise to a new generation of physicists who were able to propose radiometric estimations of the Earth's age to geologists. This digest paper describes the historical aspects of the discovery of radioactivity and of the first attempts for dating the Earth using radiometric techniques, and the strong discussions within the geologists community.

    Medical physics is a part of physics that is associated with the practice of medicine dealing with a use of various types of ionizing and non-ionizing radiation for medical purposes as well as with the radiation protection of patients and personnel. The role, responsibilities and duties of medical physicists in the fields of radiation therapy, diagnostic imaging using X-rays and magnetic resonance methods, diagnostics and therapeutic nuclear medicine, radiation dosimetry and radiation protection are discussed in this paper. It is shown that, the medical physicists have the unique possibility to combine their knowledge in medical radiation physics with the recent achievements in medicine and technology and to apply this knowledge for the adequately safe treatment or diagnosis of patients during radiological procedures.

    The role of the biomedical physicist in the education of the healthcare professions has not yet been studied in a systematic manner. This article presents the first results of an EFOMP project aimed at researching and developing this important component of the role of the biomedical physicist. A background to the study expands on the reasons that led to the need for the project. This is followed by an extensive review of the published literature regarding the role. This focuses mainly on the teaching contributions within programmes for physicians, diagnostic radiographers, radiation therapists, and the postgraduate medical specializations of radiology, radiotherapy, interventional radiology and cardiology. Finally a summary list of the specific research objectives that need to be immediately addressed is presented.

    With the profound changes currently occurring in medicine, the role of the medical physicist cannot stagnate, but must evolve to meet the challenges and opportunities that are presented. Medical physicists must understand these changes and establish themselves not only as relevant but as leaders in this new environment. We must increase our presence in clinical settings such as tumor boards, patient rounds, and the development of new diagnosis, imaging, and treatment techniques. By establishing ourselves as competent scientists, we can and must participate in the development of technologies through research, teaching, and clinical implementation. As medical physicists we must define our roles and value to our physician colleagues, patients, referring physicians, and senior administrators. We cannot afford to be viewed solely as quality assurance technologists, but need to move forward in step with medical and practice advances, becoming recognized as having a leadership role in providing quality research, technological development, and quality patient care. In this session, four leaders in medical research and healthcare will discuss their observations on how medical physicists have contributed to advancements in healthcare and opportunities to continue leadership in providing quality medicine through the applications of physics to research, education, and clinical practice. Learning Objectives: Understand the changes in the healthcare environment and how medical physicists can contribute to improving patient care. Learn how medical physicists are currently leading research efforts to improve clinical imaging and diagnosis. Understand the role of medical physicists in developing new technology and leading its translation into clinical care.

The program allows one to perform sorting or selection of specific events for subsequent processing and identification of separate particles by bubble density along the track or by the character of the decay. The fraction of protons separated automatically constituted 97%. The program has been used for processing 50 thousand events at the BEBC chamber

  12. Limited Resources, Limited Opportunities, and the Accumulation of Disadvantage: Evidence from the Global Survey of Physicists

    Ivie, Rachel

    2012-03-01

    Using the results of the Global Survey of Physicists, which we conducted in collaboration with the International Union of Pure and Applied Physics Working Group on Women, we document the effect of limited resources and opportunities on women physicists' careers. We find that women respondents are less likely than men to report access to a variety of resources and opportunities that would be helpful in advancing a scientific career. These include access to funding, travel money, lab and office space, equipment, clerical support, and availability of employees or students to help with research. When asked about specific opportunities, women report fewer invited talks and overseas research opportunities. Women who responded are less likely to have been journal editors, acted as bosses or managers, advised graduate students, served on thesis or dissertation committees, and served on committees for grant agencies. We also show the disproportionate effects of children on women physicists' careers. Women who responded are more likely than men to have changed their work situations upon becoming parents. Mothers are more likely than men and women without children to report that their careers have progressed more slowly than colleagues who finished their degrees at the same time. Furthermore, women are more likely than men to report that their careers affected the decisions they made about marriage and children. The results of this survey draw attention to the need to focus on factors other than representation when discussing the situation of women in physics. 15,000 physicists in 130 countries answered this survey, and across all these countries, women have fewer resources and opportunities and are more affected by cultural expectations concerning child care. Cultural expectations about home and family are difficult to change. However, for women to have successful outcomes and advance in physics, they must have equal access to resources and opportunities.

    This article is a tribute to the pioneering medical physicists over the last 50 years who have participated in the research, development, and commercialization of stereotactic radiosurgery (SRS) and stereotactic radiotherapy utilizing a wide range of technology. The authors have described the evolution of SRS through the eyes of physicists from its beginnings with the Gamma Knife in 1951 to proton and charged particle therapy; modification of commercial linacs to accommodate high precision SRS setups; the multitude of accessories that have enabled fine tuning patients for relocalization, immobilization, and repositioning with submillimeter accuracy; and finally the emerging technology of SBRT. A major theme of the article is the expanding role of the medical physicist from that of advisor to the neurosurgeon to the current role as a primary driver of new technology that has already led to an adaptation of cranial SRS to other sites in the body, including, spine, liver, and lung. SRS continues to be at the forefront of the impetus to provide technological precision for radiation therapy and has demonstrated a host of downstream benefits in improving delivery strategies for conventional therapy as well. While this is not intended to be a comprehensive history, and the authors could not delineate every contribution by all of those working in the pursuit of SRS development, including physicians, engineers, radiobiologists, and the rest of the therapy and dosimetry staff in this important and dynamic radiation therapy modality, it is clear that physicists have had a substantial role in the development of SRS and theyincreasingly play a leading role in furthering SRS technology

    2017-09-18

    This study was based on a survey to investigate perceptions of hadrontherapy of the members of the Italian Association of Medical Physics (AIFM). The survey was digitally submitted to the 991 members between the end of January and the beginning of April 2016. A 19-item questionnaire was designed focusing on advantages and disadvantages of hadrontherapy, current status and possible future improvements, and need and opportunities for future investments in Italy and abroad. Information about professional qualifications, main fields of clinical involvement and specific competencies of the respondents was also collected. The survey was completed by 121 AIFM members (response rate 12.2%). In the answers collected, it was shown that medical physicists expressed interest in hadrontherapy mainly for reasons of personal interest rather than for professional needs (90% ± 2.5% vs. 52% ± 4.3% of the respondents, respectively), with a good knowledge of the related basic aspects as well as of the pros and cons of its application. However, poor knowledge of the current status of hadrontherapy was observed among the medical physicists not directly involved at a professional level, who were less than 3% of the physicists working in radiotherapy. In light of these results, the implementation of new training and education initiatives should be devised to promote a deeper and global knowledge of hadrontherapy-related issues, not only from a theoretical point of view but also in practical terms. Moreover, a close collaboration between highly specialized medical physicists employed in hadrontherapy centers and others in oncology hospitals should be -encouraged.

    The inclusive production cross sections at forward rapidity of [Formula: see text], [Formula: see text], [Formula: see text](1S) and [Formula: see text](2S) are measured in [Formula: see text] collisions at [Formula: see text] with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to an integrated luminosity of 1.35 pb[Formula: see text]. Quarkonia are reconstructed in the dimuon-decay channel and the signal yields are evaluated by fitting the [Formula: see text] invariant mass distributions. The differential production cross sections are measured as a function of the transverse momentum [Formula: see text] and rapidity [Formula: see text], over the ranges [Formula: see text] GeV/c for [Formula: see text], [Formula: see text] GeV/c for all other resonances and for [Formula: see text]. The measured cross sections integrated over [Formula: see text] and [Formula: see text], and assuming unpolarized quarkonia, are: [Formula: see text] [Formula: see text]b, [Formula: see text] [Formula: see text]b, [Formula: see text] nb and [Formula: see text] nb, where the first uncertainty is statistical and the second one is systematic. The results are compared to measurements performed by other LHC experiments and to theoretical models.

  20. [Symbol: see text]2 Optimized predictive image coding with [Symbol: see text]∞ bound.

    2013-12-01

    In many scientific, medical, and defense applications of image/video compression, an [Symbol: see text]∞ error bound is required. However, pure[Symbol: see text]∞-optimized image coding, colloquially known as near-lossless image coding, is prone to structured errors such as contours and speckles if the bit rate is not sufficiently high; moreover, most of the previous [Symbol: see text]∞-based image coding methods suffer from poor rate control. In contrast, the [Symbol: see text]2 error metric aims for average fidelity and hence preserves the subtlety of smooth waveforms better than the ∞ error metric and it offers fine granularity in rate control, but pure [Symbol: see text]2-based image coding methods (e.g., JPEG 2000) cannot bound individual errors as the [Symbol: see text]∞-based methods can. This paper presents a new compression approach to retain the benefits and circumvent the pitfalls of the two error metrics. A common approach of near-lossless image coding is to embed into a DPCM prediction loop a uniform scalar quantizer of residual errors. The said uniform scalar quantizer is replaced, in the proposed new approach, by a set of context-based [Symbol: see text]2-optimized quantizers. The optimization criterion is to minimize a weighted sum of the [Symbol: see text]2 distortion and the entropy while maintaining a strict [Symbol: see text]∞ error bound. The resulting method obtains good rate-distortion performance in both [Symbol: see text]2 and [Symbol: see text]∞ metrics and also increases the rate granularity. Compared with JPEG 2000, the new method not only guarantees lower [Symbol: see text]∞ error for all bit rates, but also it achieves higher PSNR for relatively high bit rates.

  1. See laser testing at different temperatures

    Full Text Available The main problem for laser SEE testing at different temperatures is to determine correlation between laser pulse energy and LET. In the first approximation, LET values with the same laser pulse energy and different temperatures are directly proportional to the absorption coefficient of laser light in a semiconductor. Use of tabulated values could lead to errors and absorption coefficient should be determined for each sensitive volume of device under test (DUT. Temperature dependence of absorption coefficient could be determined using ionization response of DUT in power supply circuit under local laser irradiation. Using this approach a satisfactory correlation of ion and laser SEE test result was observed.

    1972-01-01

    The agreement between the Holy See and the International Atomic Energy Agency for the application of safeguards in connection with the Treaty on the Non-Proliferation of Nuclear Weapons was signed in Vienna on 26 June 1972. The preamble to the agreement states that the Holy See 'enjoys exclusive sovereignty and jurisdiction over the Vatican City State, of which the Roman Pontiff is the sovereign'. The Vatican City State, which covers a very small area, is itself 'ever and in all cases a neutral and inviolable territory', and since 18 June 1960 the whole of the Vatican City has been included in the Register of Cultural Property under Special Protection in the Event of Armed Conflict, which is deposited with the United Nations Educational, Scientific and Cultural Organization, and it has the rights and obligations which follow from its relations with third States. The Vatican City State is thus strictly adhering to the spirit of neutrality which characterizes the policy and action of the Holy See in the international community. Nevertheless, as pointed out by Monseigneur Oriano Quilici, Resident Representative of the Holy See to the Agency, 'this by no means implies that the Vatican City State cannot accept the controls and safeguards provided for under Article III of the Treaty on the Non-Proliferation of Nuclear Weapons in respect of all contracting parties'.

    Currently in the country there is not certification to serve as physicist of hospital, only require a degree of physical or related occupation (often engineering), and having gone through a few training of 6 months in hospital. Unlike in the U.S. should have a certification by the American Board of Radiology and the American Board of Medical Physics. It also must cover a postdoctoral residency in hospital at least two years in which it goes through a training that is paid. In the United Kingdom requires a university degree in Physics or career in order, is required to complete a program of four years in total (2 of theoretical and 2 of clinical practice) certified by the Institute of Physics and Engineering in Medicine, during which is also going through a training wage. Medical physicists in Canada are certified by the Canadian College of Physicists in Medicine by written examinations, which must be renewed every 5 years and have experience in the clinical setting. While in Spain, the basic requirement is to have a university degree in physics or related sciences and the certification is awarded by the Ministry of Education and Science which is due to participate in a test at the national level to a hospital residence of 3 years. One of the main aspects that require the clinical training is due to accidents caused by deficiencies in the training of responsible professionals. Examples include the Panama accident with 28 overexposed patients in 2001 and the accident of 1997 in Costa Rica. In the human resources training is needed to focus on written procedures for quality assurance of equipment, verification of processing systems, incorporating changes and improvements in the procedures themselves, keeping the workload at an acceptable level (many of errors are due to the haste with which the work must be done), medical surveillance of patients, dosimetry in vivo, and to generate recommendations to regulatory authorities.

    This is a book that the author wishes had been available to him when he was student. It reflects his interest in knowing (like expert mathematicians) the most relevant mathematics for theoretical physics, but in the style of physicists. This means that one is not facing the study of a collection of definitions, remarks, theorems, corollaries, lemmas, etc. but a narrative - almost like a story being told - that does not impede sophistication and deep results. It covers differential geometry far beyond what general relativists perceive they need to know. And it introduces readers to other areas

  17. Seeing things the philosophy of reliable observation

    CERN Document Server

    Hudson, Robert

    2014-01-01

    In Seeing Things, Robert Hudson assesses a common way of arguing about observation reports called "robustness reasoning." Robustness reasoning claims that an observation report is more likely to be true if the report is produced by multiple, independent sources. Seeing Things argues that robustness reasoning lacks the special value it is often claimed to have. Hudson exposes key flaws in various popular philosophical defenses of robustness reasoning. This philosophical critique of robustness is extended by recounting five episodes in the history of science (from experimental microbiology, atomic theory, astrophysics and astronomy) where robustness reasoning is -- or could be claimed to have been -- used. Hudson goes on to show that none of these episodes do in fact exhibit robustness reasoning. In this way, the significance of robustness reasoning is rebutted on both philosophical and historical grounds. But the book does more than critique robustness reasoning. It also develops a better defense of the infor...

    2015-10-01

    The face is a special visual stimulus. Both bottom-up processes for low-level facial features and top-down modulation by face expectations contribute to the advantages of face perception. However, it is hard to dissociate the top-down factors from the bottom-up processes, since facial stimuli mandatorily lead to face awareness. In the present study, using the face pareidolia phenomenon, we demonstrated that face awareness, namely seeing an object as a face, enhances object detection performance. In face pareidolia, some people see a visual stimulus, for example, three dots arranged in V shape, as a face, while others do not. This phenomenon allows us to investigate the effect of face awareness leaving the stimulus per se unchanged. Participants were asked to detect a face target or a triangle target. While target per se was identical between the two tasks, the detection sensitivity was higher when the participants recognized the target as a face. This was the case irrespective of the stimulus eccentricity or the vertical orientation of the stimulus. These results demonstrate that seeing an object as a face facilitates object detection via top-down modulation. The advantages of face perception are, therefore, at least partly, due to face awareness.

  2. The medical physicist: Criteria and recommendations for their academic training, clinical training and certification in Latin America

    International Nuclear Information System (INIS)

    2010-01-01

    During the last decade, the International Atomic Energy Agency (IAEA) has promoted a considerable number of technical cooperation activities and regular program linked to the establishment of educational programs in radiophysical medicine in Latin America. Despite these efforts, the amount of medical physicists in the various areas of radiological medicine (radiotherapy, nuclear medicine, radiodiagnosis) remains insufficient. In addition, many medical physicists currently associated with hospitals have inadequate training, and professional conditions (situation, salary, etc.) are very far from those of their colleagues in industrialized countries. This will result in the profession of clinical medical physicist not sufficiently attractive in Latin America. The medium-term projections indicate that the continuous evolution toward a medical care based increasingly on high technology will require even more well-trained medical physicists, thereby exacerbating the current situation. In response to the problems exposed, and considering the keen interest of the Member States of the IAEA to find a consensus solution, and an effective cooperation that would enable them to solve this problem, the ARCAL project LXXXIII was launched in 2005, strengthening the performance of medical physicists in Latin America. As part of its activities is a group of experts with the task of evaluating the problem of medical physics in the region and to develop recommendations, which are contained in this document, for harmonizing training and professional recognition of medical physicists. For the Pan American Health Organization (PAHO), medical physics is an area of special attention. For many years it has been promoting safe and effective use of radiation in health and giving technical advice to the ministries of health of Latin America and Caribbean region, in this field. Taking, therefore, on account the common interest of the IAEA and PAHO by tackling this problem, the historic and

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists who are based in a clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement for Research, Development and Training related to Nuclear Science and Technology (RCA) for the Asia-Pacific region. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in this region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in nuclear medicine was started in 2009 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experience of clinical training in Australia, Croatia and Sweden and was moderated by physicists working in the Asian region. The present publication follows the approach of earlier IAEA publications in the Training Course Series, specifically Nos 37 and 47, Clinical Training of Medical Physicists Specializing in Radiation Oncology and Clinical Training of Medical Physicists

    Brown, L.D.

    1996-01-01

    Health Physics is a profession with long, honourable traditions; and this paper could be subtitled 'Health Physics - The First 100 Years'. The discovery of X-rays by Conrad Roentgen in 1895 and of natural radioactivity by Henri Becquerel in 1896, was followed two years later by the isolation of radium by Marie and Pierre Curie and then during the last years of the nineteenth century, by explosive world wide growth in the utilisation of both these new discoveries for medical diagnostic and therapeutic purposes The fact that these new medical tools carried associated risks was very quickly learned. Physicians who most enthusiastically adopted them often experienced severe skin injuries to heavily exposed digits, and there are numerous photographs of the hands of such individuals after experiencing several amputations. Regrettably mans ultimately fatal radiation induced cancers also began to appear before the end of the last century, by the first world par there were 200 of these and the death toll already exceeded 50. In the face of this two edged weapon it is not surprising that many of the physicians and medical physicists working in this area turned a great deal of their attention from the exploitation of the new technologies to the protection of their colleagues. These individuals were the pioneer health physicists and. although this name was not used at the time, their background experience in both medicine and physics laid scientific foundations for the new discipline which have remained its keystone ever since.

    The Working Group on Women in Physics of the International Union of Pure and Applied Physics (IUPAP) subcontracted with the Statistical Research Center of the American Institute of Physics (AIP) to conduct an international study on women in physics. This study had two parts. First, we conducted a benchmarking study to identify reliable sources and collect data on the representation of women in physics in as many IUPAP member countries as possible. Second, we conducted an international survey of individual women physicists. The survey addressed issues related to both education and employment. On the education side, we asked about experiences and critical incidents from secondary school through the highest degree earned. On the employment side, we asked about how the respondents' careers had evolved and their self-assessment of how well their careers had progressed. In addition, the questionnaire also addressed issues that cut across education and employment, such as the impact of marriage and children, the factors that contributed the most toward the success they had achieved to date, and suggestions for what could be done to improve the situation of women physicists.

    The most essential achievements in 20th century biology are analyzed and the question of how throughout the last century physicists, chemists and biologists answered the question 'What is life?' is considered. The most considerable scientific achievement of 20th century biology, and perhaps of all science, is considered by many to be the discovery by biologist J Watson and physicists F Crick and M Wilkins that resulted in establishing the DNA structure. The related work of well-known scientists of the USA and Europe, E Schroedinger, L Pauling, M Perutz, J Kendrew, and of the Russian scientists N K Koltsov, N V Timofeeff-Ressovsky, G A Gamow, A M Olovnikov, is analyzed. Presently, when the structure of DNA, the process of gene expression and even the genomes of human beings are already known, scientists realize that we still do not know many of the most important things. In our opinion, the 20th century studies of nucleic acids largely ignored the principle of the cyclic organisation of DNA. In this connection, we analyze the principle of cyclicity, which in its generality may well complement the concept of the atomic structure of matter. (from the history of physics)

  7. Training requirements for health physicists in the decontamination/decommissioning field

    While a significant decrease in the number of new facilities requiring health physics surveillance has occurred in the past decade, there has been a tremendous increase in the need for health physicists to fill regulatory requirements at existing facilities and the Decontamination and Decommissioning requirements of older facilities nearing the end of their operational lifetime. There is a continuing long-term need to provide trained health physicists with the special skills to meet these requirements. Decontamination and decommissioning programs require both basic and specialized health physics activities to be performed (1) to evaluate the radiation environment of the facility under consideration, (2) to establish the standards to which cleanup activities must be pursued, and (3) to adequately protect the personnel involved in the cleanup. Performance-based training, based on job task analysis, is an appropriate way to define the different types of health physics expertise required for D and D programs. Materials have been developed to describe potential job requirements in the radiation protection field, and the appropriate training goals to meet these requirements. 14 refs., 3 tabs

    Medical Physicists have a long standing record in the advancement of the discipline of Radiation Oncology, not only in the United States but world-wide, going back to the pre-world war II era. In the United States the contributions of Failla and Quimby, first at Memorial Hospital and then at Columbia University in New York, laid the foundation for the Profession of Medical Physics in the US. Radiation Therapy first used low and high kilovoltage machines for external beam therapy. Radium (Parker) and radon seeds (Quimby) were used for brachytherapy. Subsequently, clinical Van-de-Graaff machines (Trump and Wright) and the Betatron (Kerst, Adams and Skaggs) provided the required photon beams and also made available clinically useful electron beams. The work of John Laughlin, Larry Lanzl, Jacques Ovadia together with Gail Adams and Lester Skaggs, needs to be recognized for their pioneering efforts. With the introduction of Cobalt-60 Teletherapy (Harold Johns and the Canadian Group, Gilbert Fletcher and the MD Anderson Group) and Linear Accelerators (Henry Kaplan and the Stanford Group, and Varian), in the late 1950s ∼ 1960, there was even a greater need for the strong participation of medical physicists, as a useful technical resource to the physicians

    The results of the Global Survey of Physicists draw attention to the need to focus on factors other than representation when discussing the situation of women in physics. Previous studies of women in physics have mostly focused on the lack of women in the field. This study goes beyond the obvious shortage of women and shows that there are much deeper issues. For the first time, a multinational study was conducted with approximately 15,000 respondents from 130 countries, showing that problems for women in physics transcend national borders. Across all countries, women have fewer resources and opportunities and are more affected by cultural expectations concerning child care. We show that limited resources and opportunities hurt career progress, and because women have fewer opportunities and resources, their careers progress more slowly. We also show the disproportionate effects of children on women physicists' careers. Cultural expectations about home and family are difficult to change. However, for women to have successful outcomes and advance in physics, they must have equal access to resources and opportunities.

    Walther Gerlach (1889-1979) was born in Wiesbaden-Biebrich and studied physics at the Eberhard-Karls-Universitaet in Tuebingen, where he did his doctorate in February 1912. In this work, there is no room for a complete biography either as it would exceed the scope of this thesis. It is restricted to the first part of his life, which is treated in detail. The aim of this thesis is to understand Walther Gerlach's development into a successful physicist, to find out what influenced him and to identify his achievements during this period until 1925. To gain a greater insight into his personal development the circumstances in his family as well as the conditions regarding his education in school and university will be investigated. His way of dealing with friends and colleagues is analyzed and his approaches to physical problems discussed. The personality of the physicist Gerlach rather emerges from the sum of details observed and examples quoted. However, some events in his life can be named, which show that his achievements did not happen by chance but are connected to his career. This thesis ends more or less with the beginning of the year 1925, when Gerlach accepted the chair for physics in Tuebingen.

    The American Association of Physicists in Medicine (AAPM) is a nonprofit professional society whose primary purposes are to advance the science, education and professional practice of medical physics. The AAPM has more than 8,000 members and is the principal organization of medical physicists in the United States.The AAPM will periodically define new practice guidelines for medical physics practice to help advance the science of medical physics and to improve the quality of service to patients throughout the United States. Existing medical physics practice guidelines will be reviewed for the purpose of revision or renewal, as appropriate, on their fifth anniversary or sooner.Each medical physics practice guideline represents a policy statement by the AAPM, has undergone a thorough consensus process in which it has been subjected to extensive review, and requires the approval of the Professional Council. The medical physics practice guidelines recognize that the safe and effective use of diagnostic and therapeutic radiology requires specific training, skills, and techniques, as described in each document. Reproduction or modification of the published practice guidelines and technical standards by those entities not providing these services is not authorized.The following terms are used in the AAPM practice guidelines:Must and Must Not: Used to indicate that adherence to the recommendation is considered necessary to conform to this practice guideline.Should and Should Not: Used to indicate a prudent practice to which exceptions may occasionally be made in appropriate circumstances.

    The AAPM Low Energy Brachytherapy Source Calibration Working Group was formed to investigate and recommend quality control and quality assurance procedures for brachytherapy sources prior to clinical use. Compiling and clarifying recommendations established by previous AAPM Task Groups 40, 56, and 64 were among the working group's charges, which also included the role of third-party handlers to perform loading and assay of sources. This document presents the findings of the working group on the responsibilities of the institutional medical physicist and a clarification of the existing AAPM recommendations in the assay of brachytherapy sources. Responsibility for the performance and attestation of source assays rests with the institutional medical physicist, who must use calibration equipment appropriate for each source type used at the institution. Such equipment and calibration procedures shall ensure secondary traceability to a national standard. For each multi-source implant, 10% of the sources or ten sources, whichever is greater, are to be assayed. Procedures for presterilized source packaging are outlined. The mean source strength of the assayed sources must agree with the manufacturer's stated strength to within 3%, or action must be taken to resolve the difference. Third party assays do not absolve the institutional physicist from the responsibility to perform the institutional measurement and attest to the strength of the implanted sources. The AAPM leaves it to the discretion of the institutional medical physicist whether the manufacturer's or institutional physicist's measured value should be used in performing dosimetry calculations

    Radar-pulsed microwave (MW) radiation-helped the Allies win World War II but health concerns soon arose. Alerted to a syndrome resembling mild radiation poisoning,^1 a worried M.D. surveyed radar-exposed workers, finding a high incidence of internal bleeding, 2 leukemia cases in 600 radar operators, 2 brain tumor cases in a 5-man MW research team and many complaints of headache. He sent his report^2 to the Pentagon in 1953. Alarmed Navy officers convened a meeting^3 [mostly of electrical engineers (EEs)] to identify a safe level of MW exposure for servicemen. Biophysicist Herman Schwan attended, playing a major role in establishing 10 mW/cm^2 as a thermally safe MW exposure limit. The IEEE became sole sponsor of ANSI C95 [an early health standard for radiofrequency (RF) exposure] with negative long-term consequences for human health! I review RF health standards development since 1953, comparing what physicists might have done, had they-not EEs-had this responsibility! [See also my technical abstract.] ^1 N.H.

  17. ``To See Cosmology in a Quetzal..."

    High in the Talamanca Mountains of Costa Rica, our university maintains a field station called the Quetzal Education Research Center (QERC), in cloud forest habit of the magnificent Resplendent Quetzal. At these latitudes, where every surface is alive, the astronomical realities that constrain life's options acquire an in-your-face immediacy. Three years ago we began team-teaching a general astrobiology course featuring a 10-day trip to the QERC and other Costa Rican sites, including the Arenal Volcano and Manuel Antonio National Park. This experience places the student smack in the middle of an environment that dramatically shows how stellar evolution provides the energy, materials, and timescale for biological evolution. For example, discussion of tidal forces occurs when we are up to our necks in the tide at Manuel Antonio's beaches; discussions of nuclear reactions that power the Sun are followed with extended forest hikes to see the light-gathering strategies of photosynthetic organisms; as an astronomical system, quetzal DNA is a ``metal," a product of nucleosynthesis. Our time in Costa Rica also features an astronomy education program for the residents of San Gerardo de Dota (in the rural valley where the QERC is located), with presentations at the local school and astronomy ``open house" evenings at the QERC. As one travels the country one also sees the rapid destruction of tropical forest biodiversity. We therefore encourage through astrobiology the formation of another kind of ``ecosystem:" the global network of young people who are valiantly confronting the challenges of environmental sustainability. Solutions to these problems must take into account economic, cultural, and political realities as well as scientific realities. The importance of seeing these immediate problems in terms of astronomical and biological evolution timescales forms another splendid motivation for the study of astrobiology.

    The production of K[Formula: see text](892)[Formula: see text] and [Formula: see text](1020) mesons has been measured in p-Pb collisions at [Formula: see text][Formula: see text] 5.02 TeV. K[Formula: see text] and [Formula: see text] are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range [Formula: see text]. The transverse momentum spectra, measured as a function of the multiplicity, have a p[Formula: see text] range from 0 to 15 GeV/ c for K[Formula: see text] and from 0.3 to 21 GeV/ c for [Formula: see text]. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at [Formula: see text][Formula: see text] 7 TeV and Pb-Pb collisions at [Formula: see text][Formula: see text] 2.76 TeV. In Pb-Pb and p-Pb collisions, K[Formula: see text] and [Formula: see text] probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-[Formula: see text] ratio are discussed as a function of the multiplicity of the event. The short-lived K[Formula: see text] is measured to investigate re-scattering effects, believed to be related to the size of the system and to the lifetime of the hadronic phase.

  19. PhySIC_IST: cleaning source trees to infer more informative supertrees.

    Supertree methods combine phylogenies with overlapping sets of taxa into a larger one. Topological conflicts frequently arise among source trees for methodological or biological reasons, such as long branch attraction, lateral gene transfers, gene duplication/loss or deep gene coalescence. When topological conflicts occur among source trees, liberal methods infer supertrees containing the most frequent alternative, while veto methods infer supertrees not contradicting any source tree, i.e. discard all conflicting resolutions. When the source trees host a significant number of topological conflicts or have a small taxon overlap, supertree methods of both kinds can propose poorly resolved, hence uninformative, supertrees. To overcome this problem, we propose to infer non-plenary supertrees, i.e. supertrees that do not necessarily contain all the taxa present in the source trees, discarding those whose position greatly differs among source trees or for which insufficient information is provided. We detail a variant of the PhySIC veto method called PhySIC_IST that can infer non-plenary supertrees. PhySIC_IST aims at inferring supertrees that satisfy the same appealing theoretical properties as with PhySIC, while being as informative as possible under this constraint. The informativeness of a supertree is estimated using a variation of the CIC (Cladistic Information Content) criterion, that takes into account both the presence of multifurcations and the absence of some taxa. Additionally, we propose a statistical preprocessing step called STC (Source Trees Correction) to correct the source trees prior to the supertree inference. STC is a liberal step that removes the parts of each source tree that significantly conflict with other source trees. Combining STC with a veto method allows an explicit trade-off between veto and liberal approaches, tuned by a single parameter.Performing large-scale simulations, we observe that STC+PhySIC_IST infers much more informative

  20. WE-D-207-00: CT Lung Cancer Screening and the Medical Physicist: Moving Forward

    International Nuclear Information System (INIS)

    2015-01-01

    In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancer Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology. This approach to clinical training has been successfully tested

    2015-01-01

    This biography provides a stimulating and coherent blend of scientific and personal narratives describing the many achievements of the theoretical physicist Herbert Fröhlich. For more than half a century, Fröhlich was an internationally renowned and much respected figure who exerted a decisive influence, often as a ‘man ahead of his time’, in fields as diverse as meson theory and biology. Although best known for his contributions to the theory of dielectrics and superconductivity, he worked in many other fields, his most important legacy being the pioneering introduction quantum field-theoretical methods into condensed matter physics in 1952, which revolutionised the subsequent development of the subject. Gerard Hyland has written an absorbing and informative account, in which Herbert Fröhlich’s magnetic personality shines through.

    The QuarkNet collaboration has forged new, nontraditional relationships among particle physicists, high school teachers and their students. QuarkNet provides professional development for teachers and creates opportunities for teachers and students to engage in particle physics data investigations and join research teams. Embedded in the U.S. particle research community, QuarkNet leverages the nature of particle physics research—the long duration of the experiments with extensive lead times, construction periods, and data collection and analysis periods. QuarkNet is patterned after the large collaborations with a central management infrastructure and a distributed workload across university- and lab-based research groups. We describe the important benefits of the QuarkNet outreach program that flow to university faculty and present successful strategies that others can adapt for use in their countries.

  5. The German Physical Society in the Third Reich physicists between autonomy and accommodation

    CERN Document Server

    Walker, Mark

    2012-01-01

    This is a history of one of the oldest and most important scientific societies, the German Physical Society, during the Nazi regime and immediate postwar period. When Hitler was appointed chancellor of Germany in 1933, the Physical Society included prominent Jewish scientists as members, including Fritz Haber and Albert Einstein. As Jewish scientists lost their jobs and emigrated, the Society gradually lost members. In 1938, under pressure from the Nazi Ministry of Science, Education, and Culture, the Society forced out the last of its Jewish colleagues. This action was just the most prominent example of the tension between accommodation and autonomy that characterized the challenges facing physicists in the society. They strove to retain as much autonomy as possible, but tried to achieve this by accommodating themselves to Nazi policies, which culminated in the campaign by the Society’s president to place physics in the service of the war effort.

    In nuclear medicine and radiology, what are the risks of carrying out a procedure without the presence of a qualified medical physicist and without adequate guidelines? • The patient may receive an incorrect dose which can jeopardize the success of the medical treatment or the quality of diagnosis; • The medical staff and the public might be in danger of radiation exposure; • In extreme cases, the procedure could lead to a serious accident. Globally, over 10 000 hospitals use radioisotopes in medicine, with almost 90 per cent for diagnostic procedures. Nuclear medicine technologies, both for treatment and diagnostic imaging for diseases such as cancer or cardiovascular diseases, are being constantly developed and deployed globally in health care systems

    1995-01-01

    The article presents a historic-methodological analysis of the scientific heritage of an outstanding Swiss physicist Walter Ritz (1878-1909); the analysis is based on the study of a complete collection of his works published in 1911. In addition to a general description of Ritz's works which comprise publications in spectroscopy, variational method and electrodynamics, the article deals in detail with this fundamental research into atomic spectra theory. Elastic and magnetic model of the atom proposed by Ritz for explaining atomic spectra within the framework of the classical approach are discussed. It is shown that the generalized formulas of Balmer and Rydbery, as well as the combination principle which served later as a basis for formalting Bohr's condition of frequencies, were derived by Ritz as regions corollaries of this models and were out of semiempiric nature, as was assumed. 124 refs

    We address the issue of qualifications of the niobium materials to be used for superconducting radio frequency (SCRF) cavity fabrications, from the point of view of a condensed matter physicist/materials scientist. We focus on the particular materials properties of niobium required for the functioning a SCRF cavity, and how to optimize the same properties for the best SCRF cavity performance in a reproducible manner. In this way the niobium materials will not necessarily be characterized by their purity alone, but in terms of those materials properties, which will define the limit of the SCRF cavity performance and also other related material properties, which will help to sustain this best SCRF cavity performance. Furthermore we point out the need of standardization of the post fabrication processing of the niobium-SCRF cavities, which does not impair the optimized superconducting and thermal properties of the starting niobium-materials required for the reproducible performance of the SCRF cavities according to the design values.

    The Paradigms in Physics Program at Oregon State University has adapted a variety of interactive pedagogies to engage students in `thinking like a physicist.' Video recordings of class sessions document what the students and instructor say and do. This paper discusses development of narrative interpretations of such videos. Examples are drawn from two detailed narratives of activities during which the main ideas emerged during the wrap-up discussions rather than during the tasks that the students had been doing in their small groups. The goal of these `compare and contrast' wrap-up discussions was to help the students envision connections among geometric and algebraic representations of the mathematics they would be using during the coming weeks of instruction in quantum mechanics. The purpose of the narratives is to provide examples of wrap-up discussions with commentary about ways in which the instructor was choosing to guide this process.

    The physicist Friedrich Houtermans (1903-1966) was an essential promoter and proponent of the development of physics in Berne. He introduced a number of activities in the field of elementary particles, with a special focus on the physics of cosmic rays, and important contributions in applied physics. This biography of Houtermans was written by Edoardo Amaldi and was almost finished just before his unexpected death in 1989. The editors have only corrected typographical errors and have introduced only minimal text changes in order to preserve the original content. Additionally they have collected and included unpublished pictures and memories from Houtermans’ students and collaborators. The text is the result of a thorough and intensive study on Houtermans’ life and character carried out by Edoardo Amaldi. It is more than a biography, since the figure of Houtermans is set in a historical perspective of Europe between the two world wars. This book will be of great interest to historians and historians of sci...

    This is an empirical study on the underrepresentation of people of color in scientific careers. Grounded in critical race theory, the paper examines the lived experiences of six Black women physicists and addresses obstacles faced in their career paths and strategies used to overcome these obstacles. Data for this study were collected through semi-structured interviews and coded for emergent themes. The findings reveal that college recruitment and funding were fundamental for these women to choose physics over other STEM fields. In addition, Black women experience unique challenges of socialization in STEM, particularly by exclusion of study groups. We suggest physics departments provide a more inclusive environment to support Black women in science.

    We discuss the life and career of Willie Hobbs Moore, the first African American woman to receive a doctorate degree in physics. This achievement occurred in June 1972 at the University of Michigan, Ann Arbor, MI. Her dissertation, directed by the renowned spectroscopist Samuel Krimm, was on the subject of ``A Vibrational Analysis of Secondary Chlorides," and focused on a theoretical analysis of the secondary chlorides for polyvinal-chlorine polymers. From 1972--1977, she, Krimm, and collaborators published more than thirty papers on this and related research issues. In addition to an overview of her family background, her careers as a research physicist and scientist working in various industrial laboratories, we discuss the obstacles and successes she encountered at various stages of her life.

    Many programs in experimental particle physics do not yet have a graphical interface, or demand strong platform and software requirements. With the most recent development of the VISPA project, we provide graphical interfaces to existing software programs and access to multiple computing clusters through standard web browsers. The scalable clientserver system allows analyses to be performed in sizable teams, and disburdens the individual physicist from installing and maintaining a software environment. The VISPA graphical interfaces are implemented in HTML, JavaScript and extensions to the Python webserver. The webserver uses SSH and RPC to access user data, code and processes on remote sites. As example applications we present graphical interfaces for steering the reconstruction framework OFFLINE of the Pierre-Auger experiment, and the analysis development toolkit PXL. The browser based VISPA system was field-tested in biweekly homework of a third year physics course by more than 100 students. We discuss the system deployment and the evaluation by the students.

    This authoritative biography of Herbert Fröhlich (1905-1991), a well-known theoretical physicist, paints an intimate portrait of a pioneering scientist who made seminal contributions to condensed matter physics and left his mark on other domains such as biology over a 60-year career. From his vantage point as the last graduate student of this eminent physicist, Gerard Hyland has produced an account that weaves the personal experiences and travails of Fröhlich with detailed discussion of the theory of dielectrics. The political upheavals in Europe during the 20th century provide a dramatic backdrop for the narrative.

    Quality control (QC), according to ISO definitions, represents the most basic level of quality. It is considered to be the snapshot of the performance or the characteristics of a product or service, in order to verify that it complies with the requirements. Although it is usually believed that "the role of medical physicists in Diagnostic Radiology is QC", this, not only limits the contribution of medical physicists, but is also no longer adequate to meet the needs of Diagnostic Radiology in terms of Quality. In order to assure quality practices more organized activities and efforts are required in the modern era of diagnostic radiology. The complete system of QC is just one element of a comprehensive quality assurance (QA) program that aims at ensuring that the requirements of quality of a product or service will consistently be fulfilled. A comprehensive Quality system, starts even before the procurement of any equipment, as the need analysis and the development of specifications are important components under the QA framework. Further expanding this framework of QA, a comprehensive Quality Management System can provide additional benefits to a Diagnostic Radiology service. Harmonized policies and procedures and elements such as mission statement or job descriptions can provide clarity and consistency in the services provided, enhancing the outcome and representing a solid platform for quality improvement. The International Atomic Energy Agency (IAEA) promotes this comprehensive quality approach in diagnostic imaging and especially supports the field of comprehensive clinical audits as a tool for quality improvement.

  20. Roles and Responsibilities, and Education and Training Requirements for Clinically Qualified Medical Physicists (Spanish Edition)

    International Nuclear Information System (INIS)

    2014-01-01

    The IAEA technical cooperation project Strengthening Medical Physics in Radiation Medicine was approved by the IAEA Board of Governors for the period 2009-2013 with the aim of ensuring the safe and effective diagnosis and treatment of patients. The IAEA, together with the World Health Organization and stakeholders from numerous medical physics professional societies worldwide, including the International Organization for Medical Physics (IOMP), the European Federation of Organisations for Medical Physics, the American Association of Physicists in Medicine (AAPM), the Latin American Medical Physics Association, the Asia-Oceania Federation of Organizations for Medical Physics, the European Society for Radiotherapy and Oncology, the European Commission and the International Radiation Protection Association, as well as regional counterparts from Africa, Asia, Europe and Latin America, met in Vienna in May 2009 to plan and coordinate the new project. A shortage of clinically qualified medical physicists (CQMPs), insufficient education and training (especially properly organized and coordinated clinical training), and lack of professional recognition were identified as the main problems to be addressed under this project. This publication was developed under the project framework in response to these findings. It aims, first, at defining appropriately and unequivocally the roles and responsibilities of a CQMP in specialties of medical physics related to the use of ionizing radiation, such as radiation therapy, nuclear medicine, and diagnostic and interventional radiology. Important, non-ionizing radiation imaging specialties, such as magnetic resonance and ultrasound, are also considered for completeness. On the basis of these tasks, this book provides recommended minimum requirements for the academic education and clinical training of CQMPs, including recommendations for their accreditation, certification and registration, along with continuing professional development

    A substantial barrier to the single- and multi-institutional aggregation of data to supporting clinical trials, practice quality improvement efforts, and development of big data analytics resource systems is the lack of standardized nomenclatures for expressing dosimetric data. To address this issue, the American Association of Physicists in Medicine (AAPM) Task Group 263 was charged with providing nomenclature guidelines and values in radiation oncology for use in clinical trials, data-pooling initiatives, population-based studies, and routine clinical care by standardizing: (1) structure names across image processing and treatment planning system platforms; (2) nomenclature for dosimetric data (eg, dose-volume histogram [DVH]-based metrics); (3) templates for clinical trial groups and users of an initial subset of software platforms to facilitate adoption of the standards; (4) formalism for nomenclature schema, which can accommodate the addition of other structures defined in the future. A multisociety, multidisciplinary, multinational group of 57 members representing stake holders ranging from large academic centers to community clinics and vendors was assembled, including physicists, physicians, dosimetrists, and vendors. The stakeholder groups represented in the membership included the AAPM, American Society for Radiation Oncology (ASTRO), NRG Oncology, European Society for Radiation Oncology (ESTRO), Radiation Therapy Oncology Group (RTOG), Children's Oncology Group (COG), Integrating Healthcare Enterprise in Radiation Oncology (IHE-RO), and Digital Imaging and Communications in Medicine working group (DICOM WG); A nomenclature system for target and organ at risk volumes and DVH nomenclature was developed and piloted to demonstrate viability across a range of clinics and within the framework of clinical trials. The final report was approved by AAPM in October 2017. The approval process included review by 8 AAPM committees, with additional review by ASTRO

    Single-event effects (SEE) evaluation of five different part types of next generation, commercial trench MOSFETs indicates large part-to-part variation in determining a safe operating area (SOA) for drain-source voltage (V_D_S) following a test campaign that exposed >50 samples per part type to heavy ions. These results suggest a determination of a SOA using small sample sizes may fail to capture the full extent of the part-to-part variability. An example method is discussed for establishing a Safe Operating Area using a one-sided statistical tolerance limit based on the number of test samples. Finally, burn-in is shown to be a critical factor in reducing part-to-part variation in part response. Implications for radiation qualification requirements are also explored.

  8. OpenSeesPy: Python library for the OpenSees finite element framework

    Science.gov (United States)

    Zhu, Minjie; McKenna, Frank; Scott, Michael H.

    2018-01-01

    OpenSees, an open source finite element software framework, has been used broadly in the earthquake engineering community for simulating the seismic response of structural and geotechnical systems. The framework allows users to perform finite element analysis with a scripting language and for developers to create both serial and parallel finite element computer applications as interpreters. For the last 15 years, Tcl has been the primary scripting language to which the model building and analysis modules of OpenSees are linked. To provide users with different scripting language options, particularly Python, the OpenSees interpreter interface was refactored to provide multi-interpreter capabilities. This refactoring, resulting in the creation of OpenSeesPy as a Python module, is accomplished through an abstract interface for interpreter calls with concrete implementations for different scripting languages. Through this approach, users are able to develop applications that utilize the unique features of several scripting languages while taking advantage of advanced finite element analysis models and algorithms.

    A search is presented for a high-mass Higgs boson in the [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] decay modes using the ATLAS detector at the CERN Large Hadron Collider. The search uses proton-proton collision data at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20.3 fb[Formula: see text]. The results of the search are interpreted in the scenario of a heavy Higgs boson with a width that is small compared with the experimental mass resolution. The Higgs boson mass range considered extends up to [Formula: see text] for all four decay modes and down to as low as 140 [Formula: see text], depending on the decay mode. No significant excess of events over the Standard Model prediction is found. A simultaneous fit to the four decay modes yields upper limits on the production cross-section of a heavy Higgs boson times the branching ratio to [Formula: see text] boson pairs. 95 % confidence level upper limits range from 0.53 pb at [Formula: see text] GeV to 0.008 pb at [Formula: see text] GeV for the gluon-fusion production mode and from 0.31 pb at [Formula: see text] GeV to 0.009 pb at [Formula: see text] GeV for the vector-boson-fusion production mode. The results are also interpreted in the context of Type-I and Type-II two-Higgs-doublet models.

    Energy Technology Data Exchange (ETDEWEB)

    2015-06-15

    The International Electrotechnical Commission (IEC) writes standards that manufacturers of electrical equipment must comply with. Medical electrical equipment, such as medical imaging, radiation therapy, and radiation dosimetry devices, fall under Technical Committee 62. Of particular interest to medical physicists are the standards developed within Subcommittees (SC) 62B, which addresses diagnostic radiological imaging equipment, and 62C, which addresses equipment for radiation therapy, nuclear medicine and dosimetry. For example, a Working Group of SC 62B is responsible for safety and quality assurance standards for CT scanners and a Working Group of SC 62C is responsible for standards that set requirements for dosimetric safety and accuracy of linacs and proton accelerators. IEC standards thus have an impact on every aspect of a medical physicist’s job, including equipment testing, shielding design, room layout, and workflow. Consequently, it is imperative that US medical physicists know about existing standards, as well as have input on those under development or undergoing revision. The structure of the IEC and current standards development work will be described in detail. The presentation will explain how US medical physicists can learn about IEC standards and contribute to their development. Learning Objectives: Learn about the structure of the IEC and the influence that IEC standards have on the design of equipment for radiology and radiation therapy. Learn about the mechanisms by which the US participates in the development and revision of standards. Understand the specific requirements of several standards having direct relevance to diagnostic and radiation therapy physicists.

    International Nuclear Information System (INIS)

    Meghzifene, A; Berris, T

    2016-01-01

    Purpose: To provide the professional medical physicists with adequate competencies and skills in order to help them get prepared to support Nuclear or Radiological Emergency (NRE) situations. Methods: Although clinical medical physicists working have in-depth knowledge in radiation dosimetry, including dose reconstruction and dose measurements, they are usually not involved in NRE situations. However, in a few instances where medical physicists were involved in NREs, it appeared that many lacked specific knowledge and skills that are required in such situations. This lack of specific knowledge and skills is probably due to the fact that most current medical physics curricula do not include a specific module on this topic. As a response to this finding, the IAEA decided to initiate a project to develop a specific training package to help prepare medical physicists to support NRE situations. The training package was developed with the kind support of the Government of Japan and in collaboration with Fukushima Medical University (FMU) and the National Institute of Radiological Sciences (NIRS). Results: The first International Workshop to test the training package was held in Fukushima, Japan in June 2015. It consisted of lectures, demonstrations, simulation, role play, and practical sessions followed by discussions. The training was delivered through 14 modules which were prepared with the support of 12 lecturers. A knowledge assessment test was done before the workshop, followed by the same test done at the end of the Workshop, to assess the knowledge acquired during the training. Conclusion: The Workshop was successfully implemented. The overall rating of the workshop by the participants was excellent and all participants reported that they acquired a good understanding of the main issues that are relevant to medical physics support in case of NRE situations. They are expected to disseminate the knowledge to other medical physicists in their countries.

  2. Chien-Shiung Wu: An Icon of Physicist and Woman Scientist in China

    Zhu, Yuelin

    2014-03-01

    Chien-Shiung Wu, the first female president of APS, is a well-known figure in China, a figure who serves as an inspiration for youths, especially young women, to study science and particularly physics. In this presentation, a historical perspective will be used to show how such an icon was formed. Born in 1912, the year of the Republic Revolution, Wu was in the first generation of physicists in China and her college mentor was a student of Marie Curie. When Wu came to the U.S. for graduate studies in the 1930s, it was a ``golden age'' for nuclear physics, and the invention of the cyclotron by E. O. Lawrence put UC Berkeley at the frontier. Wu was trained there, with Lawrence as her advisor, and later became an expert in Beta-decay. In 1956, Wu conceived and initiated the experiment of Cobalt-60, which, together with other two experiments, eventually proved the asymmetry of parity in weak-interactions, a hypothesis proposed by T. D. Lee and C. N. Yang. The importance of the experiment gained Wu an enormous reputation which spread even to China, when this was a period of hostility in Sino-American relations, and near total isolation due to the Cold-War. Wu was the daughter of a revolutionary, and an activist in college in patriotic student movements, and she combined this background with her scientific career as the way of ``Saving China with Science,'' a common belief reflecting the Zeitgeist of her time. Although she spent most of her life in the U.S., Wu never wavered in her love for or loyalty to her motherland. Her patriotism, as well as her scientific achievement, made Wu a legend in China, being called ``the Chinese Madam Curie.'' Even during the Cultural Revolution, a novel supposedly taking Wu as the original model was very popular in underground circles, widely spread by hand-written-copies. From 1979-1988, the CUSPEA program enrolled hundreds of China's best graduate students into physics departments in American universities. Although Wu herself was not

    High-intensity focused ultrasound (HIFU) has developed rapidly in recent years and is used frequently for clinical treatments in Asia and Europe with increasing clinical use and clinical trial activity in the US, making it an important medical technology with which the medical physics community must become familiar. Akin to medical devices that deliver treatments using ionizing radiation, HIFU relies on emitter geometry to non-invasively form a tight focus that can be used to affect diseased tissue while leaving healthy tissue intact. HIFU is unique in that it does not involve the use of ionizing radiation, it causes thermal necrosis in 100% of the treated tissue volume, and it has an immediate treatment effect. However, because it is an application of ultrasound energy, HIFU interacts strongly with tissue interfaces, which makes treatment planning challenging. In order to appreciate the advantages and disadvantages of HIFU as a thermal therapy, it is important to understand the underlying physics of ultrasound tissue interactions. The first lecture in the session will provide an overview of the physics of ultrasound wave propagation; the mechanism for the accumulation of heat in soft-tissue; image-guidance modalities including temperature monitoring; current clinical applications and commercial devices; active clinical trials; alternate mechanisms of action (future of FUS). The second part of the session will compare HIFU to existing ionization radiation techniques. The difficulties in defining a clear concept of absorbed dose for HIFU will be discussed. Some of the technical challenges that HIFU faces will be described, with an emphasis on how the experience of radiation oncology physicists could benefit the field. Learning Objectives: Describe the basic physics and biology of HIFU, including treatment delivery and image guidance techniques. Summarize existing and emerging clinical applications and manufacturers for HIFU. Understand that thermal ablation with

    Concurrent with the recognition that nuclear generated electricity must play an increasing role in worldwide energy supply and in consideration of the new nuclear power plants ordered or planned, the demand for uranium needed to fuel these reactors has already outpaced supplies. Accordingly, the price of uranium (typically expressed as US$ per pound U{sub 3}O{sub 8} equivalent) had increased significantly in recent years. As a result, numerous new and reconstituted uranium recovery projects are being developed in the United States and in other countries that possess considerable uranium ore reserves (e.g., Canada, Australia, Kazakhstan, Mongolia, Namibia, and others). It should be noted that in the United States, the current reactor fleet of 104 operating units, which generate 20 percent of the US’s base-load electricity, requires approximately 55 million pounds of U{sub 3}O{sub 8} per year, but only about 4–5 million pounds per year is produced domestically. That is, over 90 percent of current demand, ignoring anticipated increase in requirements in the near future as new plants come online, must come from foreign sources. Domestic uranium production over the last 10 years reached a low of about two million pounds in 2003 and has been increasing steadily since then. Uranium recovery as defined in this paper encompasses conventional uranium mining and milling as well as in situ recovery techniques and the recovery of uranium as a byproduct from other processes, such as phosphoric acid production. Following a brief history of uranium recovery in the US, the paper describes the basic methods and technologies associated with conventional uranium mining, conventional uranium milling and In Situ Recovery (ISR). The “health physicists perspective” is introduced into these discussions by providing summaries of the various radiological environmental monitoring and operational health physics programs that are required for these facilities.

    Now in paperback, the droll memoir by a world-class physicist that includes recollections of his involvement with pioneering laser research, encounters with many of the most recognizable literary, cultural, and entertainment figures of the 20th century, and his role in teaching ESP techniques to the CIA--a real-life X-Files saga. Russll Targ is a Zelig-like character. His story is an idiosyncratic journey through the highways and byways of American intellectual, scientific, and cultural life in 20th century. His father (the long-time editor-in-chief at Putnam) acquired The Godfather on the basis of an outline scribbled on the back of a napkin. His mother was the first press agent of the fan dancer Sally Rand. His step-mother is the legendary literary agent Rosalind Targ. He was married for thirty years to the sister of the infamous chess master Bobby Fischer. He briefly dated Henny Youngman's cousin. He attended college with Alan Alda's wife, Arlene. He was part of Ayn Rand's study group in the 1950s--along...

    Full Text Available This paper reports on research conducted by theWits/Tintswalo Community Rehabilitation, Research and Education(CORRE Programme amongst qualified community rehabilitationworkers (CRWs. The aim was to understand how CRWs see  theirrole, successes, supervision support received, problems encounteredand possible solutions.Eighteen qualified CRWs completed a questionnaire, which contained a range of open-ended and semi-structured questions.The findings included their perceived role and successes in theirwork. They were satisfied with the supervision received from theirtherapy supervisors and support from their communities. TheDepartment of Health did not support them as much as did theircommunities. The lack of government assistance for transport wastheir biggest problem: They were not always able to reach  far awayclients and spent a lot of time travelling to and from clients everyday. They were also concerned that they were not registerable withthe South African Medical and Dental Council (SAMDC.   These findings provided the Northern Province and the CommunityBased Rehabilitation (CBR manager with information to improveCBR service delivery. A two year diploma course in therapy assistance (community for CRWs, occupational and physiotherapy assistants has been started.

  8. Use of Proton SEE Data as a Proxy for Bounding Heavy-Ion SEE Susceptibility

    Although heavy-ion single-event effects (SEE) pose serious threats to semiconductor devices in space, many missions face difficulties testing such devices at heavy-ion accelerators. Low-cost missions often find such testing too costly. Even well funded missions face issues testing commercial off the shelf (COTS) due to packaging and integration. Some missions wish to fly COTS systems with little insight into their components. Heavy-ion testing such parts and systems requires access to expensive and hard-to-access ultra-high energy ion accelerators, or significant system modification. To avoid these problems, some have proposed using recoil ions from high-energy protons as a proxy to bound heavy-ion SEE rates.

    Arnold Sommerfeld is beside Albert Einstein, Niels Bohr, and Max Planck one of the founders of modern atomic and quantum theory. His career began in the 1890th years at the University of Goettingen, the world center of mathematics of that time. Since 1906 he created on the professorship for theoretical physics at the Munich university one of the most important schools of science, the students of which are well-known theorists of the atomic era like as the Nobel-price winners Hans Bethe, Peter Debye, Wolfgang Pauli, and Werner Heisenberg. He also developed far beyond his subject an unprecedented impact. He travelled as ''messenger of culture'' in many countries in order to advertise in the years after the first world war for the reputation of Germany as culture nation. By the nationalsocialism the Munich ''nursery of theoretical physics'' however was prepared an inglorious end, because Sommerfeld counted for a ''main propagandist of Jewish theories''. By the example of this life of a physicist also the eventful history of a whole subject.

  10. A Physicist's Quest in Biology: Max Delbrück and "Complementarity".

    2017-06-01

    Max Delbrück was trained as a physicist but made his major contribution in biology and ultimately shared a Nobel Prize in Physiology or Medicine. He was the acknowledged leader of the founders of molecular biology, yet he failed to achieve his key scientific goals. His ultimate scientific aim was to find evidence for physical laws unique to biology: so-called "complementarity." He never did. The specific problem he initially wanted to solve was the nature of biological replication but the discovery of the mechanism of replication was made by others, in large part because of his disdain for the details of biochemistry. His later career was spent investigating the effect of light on the fungus Phycomyces , a topic that turned out to be of limited general interest. He was known both for his informality but also for his legendary displays of devastating criticism. His life and that of some of his closest colleagues was acted out against a background of a world in conflict. This essay describes the man and his career and searches for an explanation of his profound influence. Copyright © 2017 by the Genetics Society of America.

  11. Between Industry and Academia: A Physicist's Experiences at The Aerospace Corporation

    Camparo, James

    2005-03-01

    The Aerospace Corporation is a nonprofit company whose purposes are exclusively scientific: to provide research, development, and advisory services for space programs that serve the national interest, primarily the Air Force's Space and Missile Systems Center and the National Reconnaissance Office. The corporation's laboratory has a staff of about 150 scientists who conduct research in fields ranging from Space Sciences to Material Sciences and from Analytical Chemistry to Atomic Physics. As a consequence, Aerospace stands midway between an industrial research laboratory, focused on product development, and academic/national laboratories focused on basic science. Drawing from Dr. Camparo's personal experiences, the presentation will discuss advantages and disadvantages of a career at Aerospace, including the role of publishing in peer-reviewed journals and the impact of work on family life. Additionally, the presentation will consider the balance between basic physics, applied physics, and engineering in the work at Aerospace. Since joining Aerospace in 1981, Dr. Camparo has worked as an atomic physicist specializing in the area of atomic clocks, and has had the opportunity to experiment and publish on a broad range of research topics including: the stochastic-field/atom interaction, radiation effects on semiconductor materials, and stellar scintillation.

    In 1987, the Belgian Hospital Physicists Association (BHPA) has started a program in order to uniformize the dosimetry in the Belgian radiotherapy centres. Several initiatives were taken: a) Dosimetry, of photon beams: Endorsement of the Dutch dosimetry, code of practice (NCS) (1), calibration of ionisation chambers in a common laboratory (Laboratory for standard dosimetry, RUG), on site visits where, besides mechanical checks of simulators and radiation units, absorbed dose was measured at different locations in a water phantom. Since 1987, a total of 23 centres were visited involving 18 simulators, 17 cobalt units and 22 linear accelerators with 33 photon beams. The energy of those photon beams ranged from 4 to 25 MeV (2). b) Dosimetry of electron beams: Endorsement of the Dutch dosimetry code of practice (3), calibration of several parallel plate chambers following the recommendations of the IAEA (4) and the NCS, on site visits for local measurements in electron beams. This program started last year. three centres were visited with a total of 23 energies ranging from 4.5 to 21 MeV. c) Elaboration of procedures and common reporting form for daily quality control will be published.

    Computer simulations offer tremendous opportunities for studying plasmas, ranging from simulations for students that illuminate fundamental educational concepts to research-level simulations that advance scientific knowledge. Nevertheless, there is a significant hurdle to using simulation tools. Users must navigate codes and software libraries, determine how to wrangle output into meaningful plots, and oftentimes confront a significant cyberinfrastructure with powerful computational resources. Science gateways offer a Web-based environment to run simulations without needing to learn or manage the underlying software and computing cyberinfrastructure. We discuss our progress on creating a Science Gateway for the Particle-in-Cell and Kinetic Simulation Software Center that enables users to easily run and analyze kinetic simulations with our software. We envision that this technology could benefit a wide range of plasma physicists, both in the use of our simulation tools as well as in its adaptation for running other plasma simulation software.

    CERN Multimedia

    2002-01-01

    In 1934, the eminent Russian physicist and optics specialist Sergei Ivanovitch Vavilov (1891-1951) was the first, together with Pavel Cherenkov, to observe the famous radiation we now call Cherenkov radiation, a discovery commonly used in the Laboratory's detectors. His most well-known discoveries also include that of the non-linear optical effect in 1926. Vavilov founded the Lebedev Physics Institute in Moscow, which prospered under his directorship, and contributed to the rise of nuclear physics and cosmic radiation in the USSR. The highpoint of his career came in 1945, when he was appointed President of the Soviet Academy of Sciences. However, Sergei Vavilov worked under the Stalinist dictatorship, which was responsible for the death of his elder brother, the biologist Nikolai Vavilov. His own health compromised, he died two months before his 60th birthday. His remarkable life, which is interesting not only for his scientific discoveries but also in terms of its historical context, will be the subject of...

  15. Quantum field theory III. Gauge theory. A bridge between mathematicians and physicists

    International Nuclear Information System (INIS)

    Zeidler, Eberhard

    2011-01-01

    In this third volume of his modern introduction to quantum field theory, Eberhard Zeidler examines the mathematical and physical aspects of gauge theory as a principle tool for describing the four fundamental forces which act in the universe: gravitative, electromagnetic, weak interaction and strong interaction. Volume III concentrates on the classical aspects of gauge theory, describing the four fundamental forces by the curvature of appropriate fiber bundles. This must be supplemented by the crucial, but elusive quantization procedure. The book is arranged in four sections, devoted to realizing the universal principle force equals curvature: Part I: The Euclidean Manifold as a Paradigm Part II: Ariadne's Thread in Gauge Theory Part III: Einstein's Theory of Special Relativity Part IV: Ariadne's Thread in Cohomology For students of mathematics the book is designed to demonstrate that detailed knowledge of the physical background helps to reveal interesting interrelationships among diverse mathematical topics. Physics students will be exposed to a fairly advanced mathematics, beyond the level covered in the typical physics curriculum. Quantum Field Theory builds a bridge between mathematicians and physicists, based on challenging questions about the fundamental forces in the universe (macrocosmos), and in the world of elementary particles (microcosmos).

    2004-01-01

    The specialist in Medical Physics has a key position in Quality Assurance process at diagnostic and therapeutic process and in Radiation Protection at medical use of ionizing radiation. The International Basic Safety Standards for protection against ionizing radiation of IAEA recommend and the EURATOM Directives 96/23 and 97/43 require qualified expert in medical physics to be involved in all the activities with ionizing radiation. In radiotherapeutic process this expert shall be closely involved and in nuclear medicine and diagnostic radiology this specialist shall be available. The International Organization for Medical Physics (IOMP), the European Federation of Organizations for Medical Physics (EFOMP) as well as a number of national organizations for Medical Physics in different countries have a clear concept for the qualification levels of the medical physics specialists, for the recognition scheme of their qualification and for the organization of the medical physics activities in a clinical environment. The legal requirements for medical physics expert's involvement in medicine is introducing in Bulgaria with the new Ordinance for Radiation Protection of Individuals at Medical Exposure that is expected to come into force in the beginning of next year. Some problems for discussion are submitted here finding necessary changes in the existing system for education and training of Medical physicists as well as in the organization of their involvement in health centers in the country.

  18. Leadership for Sustainable Development From the Perspective of a Woman Physicist

    Williams, Elvira S.

    2005-10-01

    What skills make a great leader? What policies lead to great programs? Answers to these challenging questions must be formulated and implemented by leaders who are successful regardless of the type organization interested in sustainable development. Leadership from both a career and an organizational viewpoint will be discussed from the perspective of a woman physicist. Implications of laws of classical and modern physics will be used in this discussion as tools for tailoring tactics for coarse- and fine-tuned guidance systems for successful leadership aimed at sustainable development. Specifically, implications of Newton's first, second and third laws of motion and the law of universal gravitation from classical physics are applied to leadership. The results are interpreted against the more refined findings of both quantum and chaos physics theories that indicate our inability to precisely predict outcomes of any event. Also, the refined theories support the notion that everything in the universe interacts with everything else in the universe at some level, so that nothing is completely isolated from anything else. Therefore, skill sets and program policies based on an interacting, all-inclusive, or holistic approaches are the ones that are most likely to generate great leaders and great programs, since these are the ones less likely to omit significant factors that could contribute to creation of great leaders.

  19. Educational pathways of Black women physicists: Stories of experiencing and overcoming obstacles in life

    This talk presents an empirical study on the underrepresentation of people of color in scientific careers. Grounded in Critical Race Theory, the presentation examines the lived experiences of six Black women physicists in the United States, addresses obstacles faced in their career paths, and strategies used to overcome these obstacles. Data for this study were collected through semi-structured interviews and coded for emergent themes, which are invitation to engage in science, communities of science practices, and isolation in the academy. The findings reveal that college recruitment and funding were fundamental for these women to choose Physics over other STEM fields. The analysis shows Physics can be a hostile environment for these women. In addition, Black women experience unique challenges of socialization in Physics, particularly by exclusion of study groups. In this talk, suggestions will be presented to make Physics departments a more inclusive space to support Black women in science. This presentation is based on work supported by the Brazilian government through CAPES (BEX1907-07-7), the Fulbright Program, Comissño Fulbright Brasil, and the Office of Diversity at Teachers College, Columbia University.

    We present results on transverse momentum ([Formula: see text]) and rapidity ([Formula: see text]) differential production cross sections, mean transverse momentum and mean transverse momentum square of inclusive [Formula: see text] and [Formula: see text] at forward rapidity ([Formula: see text]) as well as [Formula: see text]-to-[Formula: see text] cross section ratios. These quantities are measured in pp collisions at center of mass energies [Formula: see text] and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A comprehensive comparison to inclusive charmonium cross sections measured at [Formula: see text], 7 and 8 TeV is performed. A comparison to non-relativistic quantum chromodynamics and fixed-order next-to-leading logarithm calculations, which describe prompt and non-prompt charmonium production respectively, is also presented. A good description of the data is obtained over the full [Formula: see text] range, provided that both contributions are summed. In particular, it is found that for [Formula: see text] GeV/ c the non-prompt contribution reaches up to 50% of the total charmonium yield.

    The representation of the see-saw orthogonal matrix in the complex plane establishes a graphical correspondence between neutrino mass models and geometrical configurations, particularly useful to study relevant aspects of leptogenesis. We first derive the CP asymmetry bound for hierarchical heavy neutrinos and then an expression for the effective leptogenesis phase, determining the conditions for maximal phase and placing a lower bound on the phase suppression for generic models. Reconsidering the lower bounds on the lightest right-handed (RH) neutrino mass M 1 and on the reheating temperature T reh , we find that models where one of the two heavier neutrino masses is dominated by the lightest right-handed (RH) neutrinos, typically arising from connections with quark masses, undergo both phase suppression and strong wash-out such that M 1 (T reh )-bar 10 11 (10 10 ) GeV. The window 10 9 GeV-bar M 1 ,T reh -bar 10 10 GeV is accessible only for a class of models where m 1 is dominated by the lightest RH neutrino, with no straightforward connections with quark masses. Within this class we describe a new scenario of thermal leptogenesis where the baryon asymmetry of the Universe is generated by the decays of the second lightest RH neutrino, such that the lower bound on M 1 disappears and is replaced by a lower bound on M 2 . Interestingly, the final asymmetry is independent on the initial conditions. We also discuss the validity of the approximation of hierarchical heavy neutrinos in a simple analytical way

    The production of the [Formula: see text] state in proton-proton collisions is probed via its decay to the [Formula: see text] final state with the LHCb detector, in the rapidity range [Formula: see text] and in the meson transverse-momentum range [Formula: see text]. The cross-section for prompt production of [Formula: see text] mesons relative to the prompt [Formula: see text] cross-section is measured, for the first time, to be [Formula: see text] at a centre-of-mass energy [Formula: see text] using data corresponding to an integrated luminosity of 0.7 fb[Formula: see text], and [Formula: see text] at [Formula: see text] using 2.0 fb[Formula: see text]. The uncertainties quoted are, in order, statistical, systematic, and that on the ratio of branching fractions of the [Formula: see text] and [Formula: see text] decays to the [Formula: see text] final state. In addition, the inclusive branching fraction of [Formula: see text]-hadron decays into [Formula: see text] mesons is measured, for the first time, to be [Formula: see text], where the third uncertainty includes also the uncertainty on the [Formula: see text] inclusive branching fraction from [Formula: see text]-hadron decays. The difference between the [Formula: see text] and [Formula: see text] meson masses is determined to be [Formula: see text].

  3. A Different Kind of Physics Competition-the 12th International Young Physicists Tournament

    This May, five seniors from the North Carolina School of Science and Mathematics and their adult leaders, Hugh Haskell and Chuck Britton, were the first US team to compete in the International Young Physicists Tournament (IYPT), which took place in Vienna, Austria. They challenged and were challenged by eighteen similar teams from sixteen other countries. The IYPT differs from the Physics Olympiad, which is an examination, whereas the Tournament is a debate on the solution of seventeen open-ended problems published in October, on the IYPT website . The five students, Adriane Boyd, Dahl Clark, Mark Blevins, Zach Keane, and Adam Simpkins spent from mid-January until our departure on May 20, preparing their responses to the questions. In Vienna, the team was joined by Ron Edge, of the University of South Carolina, who served as jurist for the tournament. Each team pays for transportation, but once there, the host country bears all other costs. For each event, called a "physics fight," three teams are assigned their roles-reporter, opponent and reviewer. First, the opposing team selects a question. The reporters have twelve minutes to present a report. The opposing team then has five minutes to critique the report. After a rebuttal by the reporter, the reviewers discuss effectiveness of both presentations . Finally, the jurors ask questions and score each team. This year's overall winner was Germany. Taking second was the team from the Republic of Georgia. The US team did not make the semifinal round, but did well enough for a first-time competitor. Will there be another United States Team? This is an open question. Efforts are being made to find a school that can send a team to next year's competition which is scheduled for Budapest, Hungary.

  4. Medical Physics Practice Guidelines - the AAPM's minimum practice recommendations for medical physicists.

    The AAPM has long advocated a consistent level of medical physics practice, and has published many recommendations and position statements toward that goal, such as Science Council Task Group reports related to calibration and quality assurance, Education Council and Professional Council Task Group reports related to education, training, and peer review, and Board-approved Position Statements related to the Scope of Practice, physicist qualifications, and other aspects of medical physics practice. Despite these concerted and enduring efforts, the profession does not have clear and concise statements of the acceptable practice guidelines for routine clinical medical physics. As accreditation of clinical practices becomes more common, Medical Physics Practice Guidelines (MPPGs) will be crucial to ensuring a consistent benchmark for accreditation programs. To this end, the AAPM has recently endorsed the development of MPPGs, which may be generated in collaboration with other professional societies. The MPPGs are intended to be freely available to the general public. Accrediting organizations, regulatory agencies, and legislators will be encouraged to reference these MPPGs when defining their respective requirements. MPPGs are intended to provide the medical community with a clear description of the minimum level of medical physics support that the AAPM would consider prudent in clinical practice settings. Support includes, but is not limited to, staffing, equipment, machine access, and training. These MPPGs are not designed to replace extensive Task Group reports or review articles, but rather to describe the recommended minimum level of medical physics support for specific clinical services. This article has described the purpose, scope, and process for the development of MPPGs.

  5. Large Scale Management of Physicists Personal Analysis Data Without Employing User and Group Quotas

    The ability of modern HEP experiments to acquire and process unprecedented amounts of data and simulation have lead to an explosion in the volume of information that individual scientists deal with on a daily basis. Explosion has resulted in a need for individuals to generate and keep large personal analysis data sets which represent the skimmed portions of official data collections, pertaining to their specific analysis. While a significant reduction in size compared to the original data, these personal analysis and simulation sets can be many terabytes or 10s of TB in size and consist of 10s of thousands of files. When this personal data is aggregated across the many physicists in a single analysis group or experiment it can represent data volumes on par or exceeding the official production samples which require special data handling techniques to deal with effectively.In this paper we explore the changes to the Fermilab computing infrastructure and computing models which have been developed to allow experimenters to effectively manage their personal analysis data and other data that falls outside of the typically centrally managed production chains. In particular we describe the models and tools that are being used to provide the modern neutrino experiments like NOvA with storage resources that are sufficient to meet their analysis needs, without imposing specific quotas on users or groups of users. We discuss the storage mechanisms and the caching algorithms that are being used as well as the toolkits are have been developed to allow the users to easily operate with terascale+ datasets.

    Purpose: Several institutions have developed MRI guidelines for patients with MR-unsafe or MR-conditional pacemakers. Here we highlight the role of a medical physicist in implementing these guidelines for non-pacemaker dependent patients. Guidelines: Implementing these guidelines requires involvement from several medical specialties and a strong collaboration with the site MRI supervisor to develop a structured workflow. A medical physicist is required to be present during the scan to supervise the MR scanning and to maintain a safety checklist that ensures: 1) uninterrupted patient communication with the technologist, 2) continuous patient physiologic monitoring (e.g. blood pressure and electrocardiography) by a trained nurse, 3) redundant patient vitals monitoring (e.g. pulse oximetry) due to the possibility of in vivo electrocardiography reading fluctuations during image acquisition. A radiologist is strongly recommended to be available to review the images before patients are discharged from the scanner. Pacemaker MRI should be restricted to 1.5T field strength. The MRI sequences should be optimized by the physicist with regards to: a) SAR: limited to <1.5 W/Kg for MR-unsafe pacemakers in normal operating mode, b) RF exposure time: <30 min, c) Coils: use T/R coils but not restricted to such, d) Artifacts: further optimization of sequences whenever image quality is compromised due to the pacemaker. In particular, cardiac, breast and left-shoulder MRIs are most susceptible to these artifacts. Possible strategies to lower the SAR include: a) BW reduction, 2) echo-train-length reduction, 3) increase TR, 4) decrease number of averages, 5) decrease flip angle, 6) reduce slices and/or a combination of all the options. Conclusion: A medical physicist in collaboration with the MR supervisor plays an important role in the supervision/implementation of safe MR scanning of pacemaker patients. Developing and establishing a workflow has enabled our institution to scan over

    The live of the physicist Max Planck was as exciting, conflicting, and rich on catastrophes as the epoch, in which he lived. Ernst Peter Fischer draws in this fascinatingly told biography the eventful history of the Nobel-price bearer and illustrates simultaneously the unique attainment of Planck, the quantum theory of whom not only revolted the science but also changed fundamentally our picture of the world.

    Weir, V; Zhang, J

    2014-01-01

    Purpose: The role of physicist in the academic and private hospital environment continues to evolve and expand. This becomes more obvious with the newly revised requirements of the Joint Commission (JC) on imaging modalities and the continued updated requirements of ACR accreditation for medical physics (i.e., starting in June 2014, a physicists test will be needed before US accreditation). We provide an informative review on the role of diagnostic medical physicist and hope that our experience will expedite junior physicists in understanding their role in medical centers, and be ready to more opportunities. Methods: Based on our experience, diagnostic medical physicists in both academic and private medical centers perform several clinical functions. These include providing clinical service and physics support, ensuring that all ionizing radiation devices are tested and operated in compliance with the State and Federal laws, regulations and guidelines. We also discuss the training and education required to ensure that the radiation exposure to patients and staff is as low as reasonably achievable. We review the overlapping roles of medical and health physicist in some institutions. Results: A detailed scheme on the new requirements (effective 7/1/2014) of the JC is provided. In 2015, new standards for fluoroscopy, cone beam CT and the qualifications of staff will be phased in. A summary of new ACR requirements for different modalities is presented. Medical physicist have other duties such as sitting on CT and fluoroscopy committees for protocols design, training of non-radiologists to meet the new fluoroscopy rules, as well as helping with special therapies such as Yittrium 90 cases. Conclusion: Medical physicists in both academic and private hospitals are positioned to be more involved and prominent. Diagnostic physicists need to be more proactive to involve themselves in the day to day activities of the radiology department

  13. Conflicting paradigms in radiation protection: 20 Questions with answers from the regulator, the health physicist, the scientist, and the lawyers

    1995-01-01

    George Orwell's open-quotes doublethinkclose quotes should be generalized to open-quotes polythinkclose quotes to describe the multiplicity of views that radiation protection professionals must simultaneously accommodate. The paradigms, that is, organizing principles and beliefs, that (1) regulators, (2) operational health physicists, (3) scientists, (4) lawyers for the defendant, and (5) lawyers for the plaintiff use in their approaches to radiation protection are presented. What we believe as scientists often conflicts with what we do for purposes of radiation protection. What we need to do merely to protect humankind and the environment from harmful effects of radiation is far less than what we must do to satisfy the regulator, whose paradigm has checklists, score-keeping, and penalties. In the hands of lawyers, our work must overcome different challenges. Even if the paradigms of the operational health physicist, the scientist, and the regulator match, the odds against the lawyers paradigms also matching are astronomical. The differing paradigms are illustrated by example questions and answers. It is important for educators, trainers, and health physicists to recognize and separate the score-keeping, practice, science, and legal issues in health physics

    2016-06-15

    The desperate need for radiotherapy in low and mid-income countries (LMICs) has been well documented. Roughly 60 % of the worldwide incidence of cancer occurs in these resource-limited settings and the international community alongside governmental and non-profit agencies have begun publishing reports and seeking help from qualified volunteers. However, the focus of several reports has been on how dire the situation is and the magnitude of the problem, leaving most to feel overwhelmed and unsure as to how to help and why to get involved. This session will help to explain the specific ways that Medical Physicists can uniquely assist in this grand effort to help bring radiotherapy to grossly-underserved areas. Not only can these experts fulfill an important purpose, they also can benefit professionally, academically, emotionally and socially from the endeavor. By assisting others worldwide with their skillset, Medical Physicists can end up helping themselves. Learning Objectives: Understand the need for radiotherapy in LMICs. Understand which agencies are seeking Medical Physicists for help in LMICs. Understand the potential research funding mechanisms are available to establish academic collaborations with LMIC researchers/physicians. Understand the potential social and emotional benefits for both the physicist and the LMIC partners when collaborations are made. Understand the potential for collaboration with other high-income scientists that can develop as the physicist partners with other large institutions to assist LMICs.

    International Nuclear Information System (INIS)

    Seibert, J; Imbergamo, P

    2014-01-01

    The expansion and integration of diagnostic imaging technologies such as On Board Imaging (OBI) and Cone Beam Computed Tomography (CBCT) into radiation oncology has required radiation oncology physicists to be responsible for and become familiar with assessing image quality. Unfortunately many radiation oncology physicists have had little or no training or experience in measuring and assessing image quality. Many physicists have turned to automated QA analysis software without having a fundamental understanding of image quality measures. This session will review the basic image quality measures of imaging technologies used in the radiation oncology clinic, such as low contrast resolution, high contrast resolution, uniformity, noise, and contrast scale, and how to measure and assess them in a meaningful way. Additionally a discussion of the implementation of an image quality assurance program in compliance with Task Group recommendations will be presented along with the advantages and disadvantages of automated analysis methods. Learning Objectives: Review and understanding of the fundamentals of image quality. Review and understanding of the basic image quality measures of imaging modalities used in the radiation oncology clinic. Understand how to implement an image quality assurance program and to assess basic image quality measures in a meaningful way

  16. A New Approach for Education and Training of Medical Physicists in Cuba: From University to Clinical Training

    International Nuclear Information System (INIS)

    Alfonso-Laguardia, R.; Rivero Blanco, J.M.

    2016-01-01

    Full text: According to the international recommendations of IAEA and the International Organization for Medical Physics (IOMP), the education and training of clinically qualified medical physicists (CQMP) should include three main academic and professional elements: a university level education, a postgraduate education specific in medical physics (MP) and a supervised clinical training. In Cuba, most of the medical physicists working in radiation oncology (RO) or nuclear medicine (NM) services have graduated from nuclear related programmes of the High Institute on Applied Technologies and Sciences (InSTEC), who further perform a postgraduate study in medical physics (MP), at the level of a so-called Diploma course or a Master in Sciences. Nevertheless, the third level of education, namely the supervised clinical training has not yet been established, due to the lack of official recognition of the profession of MP by the health authorities. A new approach for comprehensive training of CQMP is presented, where, by maintaining the three elements of education, the process is optimized so that a medical physicist is prepared with the highest level of theoretical and clinical training, in agreement with the current demand of the advanced technologies put in service in Cuban hospitals.

    A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb[Formula: see text] of proton-proton collision data at [Formula: see text] [Formula: see text] collected with the ATLAS detector at the LHC. Data samples with enriched quark or gluon content are used in the construction and validation of templates of jet properties that are the input to the likelihood-based discriminant. The discriminating power of the jet tagger is established in both data and Monte Carlo samples within a systematic uncertainty of [Formula: see text] 10-20 %. In data, light-quark jets can be tagged with an efficiency of [Formula: see text] while achieving a gluon-jet mis-tag rate of [Formula: see text] in a [Formula: see text] range between [Formula: see text] and [Formula: see text] for jets in the acceptance of the tracker. The rejection of gluon-jets found in the data is significantly below what is attainable using a Pythia 6 Monte Carlo simulation, where gluon-jet mis-tag rates of 10 % can be reached for a 50 % selection efficiency of light-quark jets using the same jet properties.

    "What would you see if you were riding a beam of light?" This thought experiment, which Einstein reports to have "conducted" at the age of 16, of course has no sensible answer: as Einstein published a decade later, you could never reach the speed of light. But it does make sense to ask what you would see if you were traveling…

  1. How a Physicist Can Add Value In the Oil and Gas Industry

    The talk will focus on some specific examples of innovative and fit-for-purpose physics applied to solve real-world oil and gas exploration and production problems. In addition, links will be made to some of the skills and areas of practical experience acquired in physics education and research that can prove invaluable for success in such an industrial setting with a rather distinct and unique culture and a highly-collaborative working style. The oil and gas industry is one of the largest and most geographically and organizationally diverse areas of business activity on earth; and as a `mature industry,' it is also characterized by a bewildering mix of technologies dating from the 19th century to the 21st. Oil well construction represents one of the largest volume markets for steel tubulars, Portland cement, and high-quality sand. On the other hand, 3D seismic data processing, shaped-charge perforating, and nuclear well logging have consistently driven forward the state of the art in their respective areas of applied science, as much or more so than defense or other industries. Moreover, a surprising number of physicists have made their careers in the oil industry. To be successful at introducing new technology requires understanding which problems most need to be solved. The most exotic or improbable technologies can take off in this industry if they honestly offer the best solution to a real problem that is costing millions of dollars in risk or inefficiency. On the other hand, any cheaper or simpler solution that performs as well would prevail, no matter how inelegant! The speaker started out in atomic spectroscopy (Harvard), post-doc'ed in laser cooling and trapping of ions for high-accuracy time and frequency metrology (NIST), and then jumped directly into Drilling Engineering with Schlumberger Corp. in Houston. Since then, his career has moved through applied electromagnetics, geological imaging, nuclear magnetic resonance logging, some R and D portfolio

    A measurement is presented of the [Formula: see text] production cross section at [Formula: see text] = 7 TeV using [Formula: see text] collision data corresponding to an integrated luminosity of 383 [Formula: see text], collected with the ATLAS experiment at the LHC. Selection of [Formula: see text](1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. The differential cross section is measured as a function of the transverse momentum, [Formula: see text], and rapidity, [Formula: see text], of the [Formula: see text](1020) meson in the fiducial region 500 [Formula: see text] 1200 MeV, [Formula: see text] 0.8, kaon [Formula: see text] 230 MeV and kaon momentum [Formula: see text] 800 MeV. The integrated [Formula: see text]-meson production cross section in this fiducial range is measured to be [Formula: see text] = 570 [Formula: see text] 8 (stat) [Formula: see text] 66 (syst) [Formula: see text] 20 (lumi) [Formula: see text].

  3. Enhanced learning through scale models and see-thru visualization

    Kelley, M.D.

    1987-01-01

    The development of PowerSafety International's See-Thru Power Plant has provided the nuclear industry with a bridge that can span the gap between the part-task simulator and the full-scope, high-fidelity plant simulator. The principle behind the See-Thru Power Plant is to provide the use of sensory experience in nuclear training programs. The See-Thru Power Plant is a scaled down, fully functioning model of a commercial nuclear power plant, equipped with a primary system, secondary system, and control console. The major components are constructed of glass, thus permitting visual conceptualization of a working nuclear power plant

  4. The Delicate Balance between Research, Teaching and Outreach: A Case Study of Physicists in K-12 Education

    Science.gov (United States)

    Leslie-Pelecky, Diandra

    2003-04-01

    Recent calls from a variety of sectors including some funding agencies and professional societies encourage physicists to take a more active interest in the education of K-12 students and their teachers. Although there are a broad range of possible activities, finding time to participate is always a challenge for the researcher. How does the busy physicist ensure that the time devoted to education or outreach activities produces meaningful results without adversely affecting his or her research program? Project Fulcrum, a NSF-funded program that teams science and math graduate students at the University of Nebraska-Lincoln with 4th -8th grade teachers in the Lincoln Public Schools, presents a case study of how research scientists can be meaningfully involved with K-12 education. Project Fulcrum's preliminary results indicate that the impact scientists have in the classroom goes far beyond providing expertise in physics, and turns out to be very different than originally anticipated. There are a wide variety of models for involvement in education and outreach that cover a broad span of time and energy commitments. Careful project choice, establishing administrative infrastructure, collaborating with other departments and colleges, and involving colleagues can optimize the impact-made-to-time-spent ratio. Challenges such as project evaluation, overcoming the negative attitudes of some physicists towards anything not related to research, and ensuring that participants get appropriate credit for their efforts will also be discussed. The conclusion will address the personal and professional rewards of involvement in education and outreach. This work is funded by the National Science Foundation (NSF-DGE0086358). The author wishes to acknowledge the contributions of co-PIs G. Buck, S. Kirby, R. Kirby and P. Dussault, and all of the Project Fulcrum Fellows and Teachers.

  5. The nuclear shield in the 'thirty-year war' of physicists against ignorant criticism of modern physical theories

    International Nuclear Information System (INIS)

    Vizgin, Vladimir P

    1999-01-01

    This article deals with the almost 'thirty-year war' led by physicists against the authorities' incompetent philosophical and ideological interference with science. The 'war' is shown to have been related to the history of Soviet nuclear weapons. Theoretical milestones of 20th century physics, to wit, theory of relativity and quantum mechanics, suffered endless 'attacks on philosophical grounds'. The theories were proclaimed idealistic as well as unduly abstract and out of touch with practice; their authors and followers were labelled 'physical idealists', and later, in the 1940s and 1950s, even 'cosmopolitans without kith or kin'. Meanwhile, quantum and relativistic theories, as is widely known, had become the basis of nuclear physics and of the means of studying the atomic nucleus (charged particle accelerators, for instance). The two theories thus served, to a great extent, as a basis for both peaceful and military uses of nuclear energy, made possible by the discovery of uranium nuclear fission under the action of neutrons. In the first part, the article recounts how prominent physicists led the way to resisting philosophical and ideological pressure and standing up for relativity, quantum theories and nuclear physics, thus enabling the launch of the atomic project. The second part contains extensive material proving the point that physicists effectively used the 'nuclear shield' in the 1940s and 1950s against the 'philosophical-cosmopolitan' pressure, indeed saving physics from a tragic fate as that of biology at the Academy of Agricultural Sciences (VASKhNIL) session in 1948.

    King, A.G.

    1994-08-01

    The Pacific Northwest Laboratory (PNL)/Analytical Chemistry Laboratory (ACL) and the Westinghouse Hanford Company (WHC)/Process Analytical Laboratory (PAL) provide analytical support services to various environmental restoration and waste management projects/programs at Hanford. In response to a US Department of Energy -- Richland Field Office (DOE-RL) audit, which questioned the comparability of analytical methods employed at each laboratory, the Sample Exchange/Exchange (SEE) program was initiated. The SEE Program is a selfassessment program designed to compare analytical methods of the PAL and ACL laboratories using sitespecific waste material. The SEE program is managed by a collaborative, the Quality Assurance Triad (Triad). Triad membership is made up of representatives from the WHC/PAL, PNL/ACL, and WHC Hanford Analytical Services Management (HASM) organizations. The Triad works together to design/evaluate/implement each phase of the SEE Program
