This book gives an introduction in methods, contents, and results of modern solid-state physics. It is based on the fundamental course of theoretical physics, i. e. presupposed are knowledges in classical mechanics, electrodynamics, and especially quantum mechanics and statistical physics, as they are mediated in the at all German-speaking universities usual course in theoretical physics generally until the end of the 6th special semester. The especially for the treatment of many-body effects unavoidable formalism of the 2nd quantization (occupation number representation) is introduced and used in the book. The content reaches from the classical fields of solid-state physics (phonons and electrons in the periodic potentia, Bloch theorem, Hartree-Fock approximation, electron-phonon interactions) through fields of applications as superconductivity and magnetism until fields, which are actual object of research (for instance quantum Hall effect, high-temperature superconductivity).

The "International Workshop on Theoretical Plasma Physics: Modern Plasma Science was held at the Abdus Salam International Centre for Theoretical Physics (Abdus Salam ICTP), Trieste, Italy during the period 5 16 July 2004. The workshop was organized by P K Shukla, R Bingham, S M Mahajan, J T Mendonça, L Stenflo, and others. The workshop enters into a series of previous biennial activities that we have held at the Abdus Salam ICTP since 1989. The scientific program of the workshop was split into two parts. In the first week, most of the lectures dealt with problems concerning astrophysical plasmas, while in the second week, diversity was introduced in order to address the important role of plasma physics in modern areas of science and technology. Here, attention was focused on cross-disciplinary topics including Schrödinger-like models, which are common in plasma physics, nonlinear optics, quantum engineering (Bose-Einstein condensates), and nonlinear fluid mechanics, as well as emerging topics in fundamental theoretical and computational plasma physics, space and dusty plasma physics, laser-plasma interactions, etc. The workshop was attended by approximately hundred-twenty participants from the developing countries, Europe, USA, and Japan. A large number of participants were young researchers from both the developing and industrial countries, as the directors of the workshop tried to keep a good balance in inviting senior and younger generations of theoretical, computational and experimental plasma physicists to our Trieste activities. In the first week, there were extensive discussions on the physics of electromagnetic wave emissions from pulsar magnetospheres, relativistic magnetohydrodynamics of astrophysical objects, different scale sizes turbulence and structures in astrophysics. The scientific program of the second week included five review talks (60 minutes) and about thirty invited topical lectures (30 minutes). In addition, during the two weeks, there

This comprehensive textbook on relativity integrates Newtonian physics, special relativity and general relativity into a single book that emphasizes the deep underlying principles common to them all, yet explains how they are applied in different ways in these three contexts. Newton's ideas about how to represent space and time, his laws of dynamics, and his theory of gravitation established the conceptual foundation from which modern physics developed. Book I in this volume offers undergraduates a modern view of Newtonian theory, emphasizing those aspects needed for understanding quantum and relativistic contemporary physics. In 1905, Albert Einstein proposed a novel representation of space and time, special relativity. Book II presents relativistic dynamics in inertial and accelerated frames, as well as a detailed overview of Maxwell's theory of electromagnetism. This provides undergraduate and graduate students with the background necessary for studying particle and accelerator physics, astrophysics and ...

In this book, important conceptual developments of the two major revolutions of modern physics - the quantum and relativity theories - are presented in a nonmathematical, dialectical form of dialogue. The implications of conflicting philosophical attitudes of these revolutions in physics and applications to topics such as cosmology/astrophysics and high energy physics are emphasized. It is argued that for any substantial progress in our understanding of 21st century physics, it will be necessary to resolve these 20th century conflicts. These richly rewarding dialogues provide a starting point

Much of our understanding of physics in the last 30-plus years has come from research on atoms, photons, and their interactions. Collecting information previously scattered throughout the literature, Modern Atomic Physics provides students with one unified guide to contemporary developments in the field. After reviewing metrology and preliminary material, the text explains core areas of atomic physics. Important topics discussed include the spontaneous emission of radiation, stimulated transitions and the properties of gas, the physics and applications of resonance fluorescence, coherence, cooling and trapping of charged and neutral particles, and atomic beam magnetic resonance experiments. Covering standards, a different way of looking at a photon, stimulated radiation, and frequency combs, the appendices avoid jargon and use historical notes and personal anecdotes to make the topics accessible to non-atomic physics students. Written by a leader in atomic and optical physics, this text gives a state-of-the...

Modern Introductory Physics, 2nd Edition, by Charles H. Holbrow, James N. Lloyd, Joseph C. Amato, Enrique Galvez, and Beth Parks, is a successful innovative text for teaching introductory college and university physics. It is thematically organized to emphasize the physics that answers the fundamental question: Why do we believe in atoms and their properties? The book provides a sound introduction to basic physical concepts with particular attention to the nineteenth- and twentieth-century physics underlying our modern ideas of atoms and their structure. After a review of basic Newtonian mechanics, the book discusses early physical evidence that matter is made of atoms. With a simple model of the atom Newtonian mechanics can explain the ideal gas laws, temperature, and viscosity. Basic concepts of electricity and magnetism are introduced along with a more complicated model of the atom to account for the observed electrical properties of atoms. The physics of waves---particularly light and x-rays---an...

The theoretical physics program in the Physics Division at ORNL involves research in both nuclear and atomic physics. In nuclear physics there is extensive activity in the fields of direct nuclear reactions with light- and heavy-ion projectiles, the structure of nuclei far from stability and at elevated temperatures, and the microscopic and macroscopic description of heavy-ion dynamics, including the behavior of nuclear molecules and supernuclei. New research efforts in relativistic nuclear collisions and in the study of quark-gluon plasma have continued to grow this year. The atomic theory program deals with a variety of ionization, multiple-vacancy production, and charge-exchange processes. Many of the problems are selected because of their relevance to the magnetic fusion energy program. In addition, there is a joint atomic-nuclear theory effort to study positron production during the collision of two high-Z numbers, i.e., U+U. A new Distinguished Scientist program, sponsored jointly by the University of Tennessee and ORNL, has been initiated. Among the first appointments is G.F. Bertsch in theoretical physics. As a result of this appointment, Bertsch and an associated group of four theorists split their time between UT and ORNL. In addition, the State of Tennessee has established a significant budget to support the visits of outstanding scientists to the Joint Institute for Heavy Ion Research at ORNL. This budget should permit a significant improvement in the visitor program at ORNL.

First the illustrative approach via wave mechanics is reproduced. The more abstract Hilbert-space formulation introduces the author later by postulates, which are because of the preceding wave mechanics sufficiently plausible. All concepts of quantum mechanics, which contradict often to the intuitive understanding formed by macroscopic experiences, are extensively discussed and made by means of many examples as well as problems - in the largest part provided with solutions - understandable. To the interpretation of quantum mechanics an extensive special chapter is dedicated. this book arose from courses on theoretical physics, which the author has held at the Heinrich-Heine University in Duesseldorf, and was in numerous repetitions fitted to the requirement of the studyings. it is so designed that it is also after the study suited as reference book or for the renewing. All problems are very thoroughly and such extensively studied that each step is separately reproducible. About motivation and good understandability is cared much

Max Planck (1858-1947) is according to the words of Max von Laue the ''father of quantum physics''. This characteristic has until today continuance, although Planck stood for long time sceptically in front of his quantum hypothesis and so became a revolutionary in spite of his wishes. Eclipted by this pioneer role of the scholar for the foundation of the quantum theory are the numerous further works of the scholer, by which he has in many other fields provided eminent things. Starting with his fundamental contribution to thermodynamics, which make him to an excellent researcher of the field, until the works in the early history of relativity theory and the promotion of the young Einstein, which let him become also to a pioneer of the second central pillar of modern physics. The present collection attempts to show the whole spectrum of the physical works of Max Planck and his role in the formation of modern physics. [de

We summarize the results of a research into the nature of the new physical phenomena observed in the interactions of photons and neutrinos of energies ≤ 1 EeV, emitted by various point sources in the sky. Contrary to expectations based on the Standard Model, the extensive air showers generated by these particles contain too many muons by a factor of (approximately) 100. This phenomenon can be explained by a composite structure of neutrinos, such that at sufficiently high energies they develop strong interactions. This hypothesis can be tested by studying the absorption characteristics of the primaries on the 3 degree K background. We find that the primaries contain a component which, unlike photons, is not absorbed by the background. It interacts with a cross section of a few mb/nucleon, thus giving further evidence for the existence of a substructure of quarks and leptons
Rational reconstructions of modern physics
Mittelstaedt, Peter
2013-01-01
Newton’s classical physics and its underlying ontology are loaded with several metaphysical hypotheses that cannot be justified by rational reasoning nor by experimental evidence. Furthermore, it is well known that some of these hypotheses are not contained in the great theories of Modern Physics, such as the theory of Special Relativity and Quantum Mechanics. This book shows that, on the basis of Newton’s classical physics and by rational reconstruction, the theory of Special Relativity as well as Quantum Mechanics can be obtained by partly eliminating or attenuating the metaphysical hypotheses. Moreover, it is shown that these reconstructions do not require additional hypotheses or new experimental results. In the second edition the rational reconstructions are completed with respect to General Relativity and Cosmology. In addition, the statistics of quantum objects is elaborated in more detail with respect to the rational reconstruction of quantum mechanics. The new material completes the approach of t...

Lattice Boltzmann algorithms are a mesoscopic method to solve problems in nonlinear physics which are highly parallelized – unlike the direction solution of the original problem. These methods are applied to both fluid and magnetohydrodynamic turbulence. By introducing entropic constraints one can enforce the positive definiteness of the distribution functions and so be able to simulate fluids at high Reynolds numbers without numerical instabilities. By introducing a vector distribution function for the magnetic field one can enforce the divergence free condition on the magnetic field automatically, without the need of divergence cleaning as needed in most direct numerical solutions of the resistive magnetohydrodynamic equations. The principal reason for the high parallelization of lattice Boltzmann codes is that they consist of a kinetic collisional relaxation step (which is purely local) followed by a simple shift of the relaxed data to neighboring lattice sites. In large eddy simulations, the closure schemes are highly nonlocal – the most famous of these schemes is that due to Smagorinsky. Under a lattice Boltzmann representation the Smagorinsky closure is purely local – being simply a particular moment on the perturbed distribution fucntions. After nonlocal fluid moment models were discovered to represent Landau damping, it was found possible to model these fluid models using an appropriate lattice Boltzmann algorithm. The close to ideal parallelization of the lattice Boltzmann codes permitted us to be Gordon Bell finalists on using the Earth Simulation in Japan. We have also been involved in the radio frequency propagation of waves into a tokamak and into a spherical overdense tokamak plasma. Initially we investigated the use of a quasi-optical grill for the launching of lower hybrid waves into a tokamak. It was found that the conducting walls do not prevent the rods from being properly irradiated, the overloading of the quasi-optical grill is not severe

Shirkov, D.V.
1988-01-01
Renormalization groups used in diverse fields of theoretical physics are considered. The discussion is based upon functional formulation of group transformations. This attitude enables development of a general method by using the notion of functional self-similarity which generalizes the usual self-similarity connected with power similarity laws. From this point of view the authors present a simple derivation of the renorm-group (RG) in QFT liberated from ultra-violet divergences philosophy, discuss the RG approach in other fields of physics and compare different RG's

Modern trends in theoretical radiation chemistry development
International Nuclear Information System (INIS)
Kaplan, I.G.
1983-01-01
Most important trends in the development of radiation chemitry theory are considered. Wide use of electronic computers for modeling different stages of radiolysis in conjUnction with advanced precision experimental methods (picosecond pulse radiolysis, acceptor additions method, magnetic method of detecting interstitial active particles) is noted. Information obtained in photochemistry and molecular spectroscopy, including laser photolysis, is in common use in developing the theory. It is noted that data on the processes occurring within less than 10 -12 s time can be obtained now only on the base of theoretical representations about the mechanism of ionizing irradiation interaction with molecular medium. Therefore, special attention in the review is paid to investigation of primary radiolysis processes. Besides investigation of primary medium excitation processes theoretical investigations into the ways of energy degradation, knocked out electrons and their further state are continued. It is noted that a considerable number of papers deal with the nature and behaviour of radiation-induced excess electrons in non-polar solutions and solid matrices. Works on application of diffusion kinetics in radiolysis have been developed in recent years
Philosophical problems of modern physics
International Nuclear Information System (INIS)
Mittelstaedt, P.
1976-01-01
This book treats the philosophical problems that have arisen in connection with the theories of relativity and quantum theory. The book begins with a discussion of the problems that were raised by the special theory of relativity; questions relating to the structure of space and time, especially the problem of the temporal sequence of events. Subsequently problems are considered that were raised by the general theory of relativity, and which question the validity and applicability of Euclidean geometry to empirical space. The physical results, and in particular the theory of the measuring process in quantum mechanics, are considered. Criticism of the concept of substance and of the law of causality in quantum theory are discussed. Finally, the validity and applicability of classical logic for the domain of quantum-theoretical propositions are dealt with. (B.R.H.)

Research in theoretical nuclear physics
International Nuclear Information System (INIS)
Udagawa, T.
1993-11-01
This report describes the accomplishments in basic research in nuclear physics carried out by the theoretical nuclear physics group in the Department of Physics at the University of Texas at Austin, during the period of November 1, 1992 to October 31, 1993. The work done covers three separate areas, low-energy nuclear reactions, intermediate energy physics, and nuclear structure studies. Although the subjects are thus spread among different areas, they are based on two techniques developed in previous years. These techniques are a powerful method for continuum-random-phase-approximation (CRPA) calculations of nuclear response and the breakup-fusion (BF) approach to incomplete fusion reactions, which calculation on a single footing of various incomplete fusion reaction cross sections within the framework of direct reaction theories. The approach was developed as a part of a more general program for establishing an approach to describing all different types of nuclear reactions, i.e., complete fusion, incomplete fusion and direct reactions, in a systematic way based on single theoretical framework
Einstein's impact on theoretical physics
International Nuclear Information System (INIS)
Yang, C.N.
1983-01-01
There occurred in the early years of this century three conceptual revolutions that profoundly changed Man's understanding of the physical universe: the special theory of relativity (in 1905), the general theory of relativity (1915) and quantum mechanics (1925). Einstein personally was responsible for the first two of these revolutions, and influenced and helped to shape the third. But it is not about his work in these conceptual revolutions that he writes about here. Much has been written about that work already. Instead, he discusses, in general terms, Einstein's insights on the structure of theoretical physics and their relevance to the development of physics in the second half of this century. He divides the discussion into four sections which are, of course, very much related

Theoretical perspectives on strange physics
International Nuclear Information System (INIS)
Ellis, J.
1983-04-01
Kaons are heavy enough to have an interesting range of decay modes available to them, and light enough to be produced in sufficient numbers to explore rare modes with satisfying statistics. Kaons and their decays have provided at least two major breakthroughs in our knowledge of fundamental physics. They have revealed to us CP violation, and their lack of flavor-changing neutral interactions warned us to expect charm. In addition, K 0 -anti K 0 mixing has provided us with one of our most elegant and sensitive laboratories for testing quantum mechanics. There is every reason to expect that future generations of kaon experiments with intense sources would add further to our knowledge of fundamental physics. This talk attempts to set future kaon experiments in a general theoretical context, and indicate how they may bear upon fundamental theoretical issues. A survey of different experiments which would be done with an Intense Medium Energy Source of Strangeness, including rare K decays, probes of the nature of CP isolation, μ decays, hyperon decays and neutrino physics is given

The Six Core Theories of Modern Physics
Stevens, Charles F.
1996-09-01
Charles Stevens, a prominent neurobiologist who originally trained as a biophysicist (with George Uhlenbeck and Mark Kac), wrote this book almost by accident. Each summer he found himself reviewing key areas of physics that he had once known and understood well, for use in his present biological research. Since there was no book, he created his own set of notes, which formed the basis for this brief, clear, and self-contained summary of the basic theoretical structures of classical mechanics, electricity and magnetism, quantum mechanics, statistical physics, special relativity, and quantum field theory. The Six Core Theories of Modern Physics can be used by advanced undergraduates or beginning graduate students as a supplement to the standard texts or for an uncluttered, succinct review of the key areas. Professionals in such quantitative sciences as chemistry, engineering, computer science, applied mathematics, and biophysics who need to brush up on the essentials of a particular area will find most of the required background material, including the mathematics.

Quantum theoretical physics is statistical and relativistic
International Nuclear Information System (INIS)
Harding, C.
1980-01-01
A new theoretical framework for the quantum mechanism is presented. It is based on a strict deterministic behavior of single systems. The conventional QM equation, however, is found to describe statistical results of many classical systems. It will be seen, moreover, that a rigorous synthesis of our theory requires relativistic kinematics. So, QM is not only a classical statistical theory, it is, of necessity, a relativistic theory. The equation of the theory does not just duplicate QM, it indicates an inherent nonlinearity in QM which is subject to experimental verification. It is shown, therefore, that conventional QM is a corollary of classical deterministic principles. It is suggested that this concept of nature conflicts with that prevalent in modern physics.

Theoretical Physics. Lectures presented at the Seminar on Theoretical Physics
International Nuclear Information System (INIS)
1963-01-01
The seminar on Theoretical Physics was held in Trieste, Italy, from 16 July to 25 of August 1962 and was organized by the International Atomic Energy Agency. The published proceedings of the lectures consist of five books. Book I is concerned with quantum field theory in its axiomatic as well as lagrangian formulations. Part 1 is a survey by Wightman of the recent achievements of the axiomatic approach followed by an account from Wigner of some of the less known representations of the Lorentz Group (continuous spin and imaginary mass representations) which may possibly acquire relevance in connection with theories of Regge poles. Part two of Book I consists of Schwinger’s lectures on the structure of Gauge Theories of Vector Particles and an account of his recent ideas about gauge invariance and its connection with mass. Book II is devoted to the symmetry properties of elementary particles with an experimental review by Capps and a survey of the formalism of Lie groups by Salam. A number of contributions by Gatto, Sakurai and others specialize to particular Lie groups, exploring the possibility of testing which, if any, of the higher symmetries are in fact realized in nature. Book III is concerned with complex angular momenta and Mandelstam representation, with major lecture courses from Regge, Fubini, Mandelstam and Froissart. A shorter Book IV surveys some recent dynamical investigations of πN and NN Systems as well as compound models of elementary particles (Thirring). The concluding part of this volume (Book V) is different in spirit from the rest. Its concern is with the emerging topic of very high energies, with a survey of strong interactions from Hayakawa, of electromagnetic interactions from Ericsson and others and of weak interactions at very high energies from Pais.

This proposal focuses on research on three distinct areas of particle physics: (1) Nonperturbative QCD. I tend to continue work on analytic modelling of nonperturbative effects in the strong interactions. I have been investigating the theoretical connection between the nonrelativistic quark model and QCD. The primary motivation has been to understand the experimental observation of nonzero matrix elements involving current strange quarks in ordinary matter -- which in the quark model has no strange quark component. This has led to my present work on understanding constituent (quark model) quarks as collective excitations of QCD degrees of freedom. (2) Weak Scale Baryogenesis. A continuation of work on baryogenesis in the early universe from weak interactions. In particular, an investigation of baryogenesis occurring during the weak phase transition through anomalous baryon violating processes in the standard model of weak interactions. (3) Flavor and Compositeness. Further investigation of a new mechanism that I recently discovered for dynamical mass generation for fermions, which naturally leads to a family hierarchy structure. A discussion of recent past work is found in the next section, followed by an outline of the proposed research. A recent publication from each of these three areas is attached to this proposal

BOOK REVIEW: Modern Physics, 3rd edn
Lovett, David
1999-09-01
The number of broadly based physics texts written at a level corresponding to second year and above of UK physics degrees is limited. This is such a book thoroughly updated in a third edition, the first edition having been published 20 years ago. The book is unusual in that the reader is referred to the Freeman website www.whfreeman.com/physics for some additional sections. It will be interesting to see whether this proves to be an attractive feature. The coverage reflects the US emphasis on topics and contains both theoretical and experimental details. It should not be regarded as an introductory text although it is clearly written. Thus the first two chapters take the reader straight into relativity, concentrating mainly on special relativity but going on to general relativity. From here the reader is led to ideas of quantization of charge, light and energy, followed by an exploration of the nuclear atom, wavelike properties of particles and Schrödinger's equation. Solution of this equation for the hydrogen atom introduces a section on spectroscopy. The next chapter on statistical physics includes Fermi-Dirac and Bose-Einstein statistics and brings to a close Part 1, which concentrates on the theoretical groundwork. Consistent with its title, the book does not cover traditional aspects of thermodynamics and electromagnetic theory. Part 2 is entitled `Applications' and begins with a chapter on molecular structure and spectra. Lasers and masers are included here but geometrical, physical and nonlinear optics get limited or no coverage. Solid state physics follows but, despite the title of the book, there is little on modern devices, although the section on superconductivity mentions high temperature materials. The chapters on nuclear physics, fission, fusion reactors and medical applications and a chapter on particle physics are comprehensive. Finally a chapter on astrophysics and cosmology is referred to, but the reader must find this at the website. As this is

Formation of modern theoretical regulations about organization concerning management development
Directory of Open Access Journals (Sweden)
Zhalinska I.V.
2017-03-01
Full Text Available The article deals with the scientific concepts about an organization as the entity of management concerning management development. The author studies the principal theoretical regulations about an organization within the most spread schools of management and context of development of other managerial concepts in particular, strategic management. It is found out that an organization and its development had not considered as the factor of an effective activity before. Researches paid their attention to single aspects of organization activity where the aspects allowed to increase economic efficiency. However, the objective complication of conditions of enterprises’ activities caused the necessity of scientific research of adequate models of functioning and development of organizations, which currently cannot be provided by traditional management concepts. Thus, theoretical and practical prerequisites arise for a separate scientific set of researches within the science of management such as the theory of an organization. The article describes the main classified approaches to the models of an organization. The paper researches the challenges in present management, and those ones, which have caused the crisis in modern management. It is singled out the following actual aspects of modern organizational processes as the all-round use of modern information and computer systems, the development of integration and in cooperation in management, the appearance of new management technologies, the use of new assessment criteria for organization activity, striving for organizational shifts and innovations. Due to the generalization of the study results, the authors single out such key aspects in the development of the science of management, as the crisis of traditional management influences upon practical activity of modern organizations; the achievements of traditional management schools are becoming necessary, but not determinant factors of organization
Modern physics for scientists and engineers
Morrison, John C
2015-01-01
The second edition of Modern Physics for Scientists and Engineers is intended for a first course in modern physics. Beginning with a brief and focused account of the historical events leading to the formulation of modern quantum theory, later chapters delve into the underlying physics. Streamlined content, chapters on semiconductors, Dirac equation and quantum field theory, as well as a robust pedagogy and ancillary package, including an accompanying website with computer applets, assist students in learning the essential material. The applets provide a realistic description of the energy levels and wave functions of electrons in atoms and crystals. The Hartree-Fock and ABINIT applets are valuable tools for studying the properties of atoms and semiconductors.

Nonequilibrium statistical physics a modern perspective
Livi, Roberto
2017-01-01
Statistical mechanics has been proven to be successful at describing physical systems at thermodynamic equilibrium. Since most natural phenomena occur in nonequilibrium conditions, the present challenge is to find suitable physical approaches for such conditions: this book provides a pedagogical pathway that explores various perspectives. The use of clear language, and explanatory figures and diagrams to describe models, simulations and experimental findings makes the book a valuable resource for undergraduate and graduate students, and also for lecturers organizing teaching at varying levels of experience in the field. Written in three parts, it covers basic and traditional concepts of nonequilibrium physics, modern aspects concerning nonequilibrium phase transitions, and application-orientated topics from a modern perspective. A broad range of topics is covered, including Langevin equations, Levy processes, directed percolation, kinetic roughening and pattern formation.

During the past year, the authors have concentrated on (1) divertor physics, (2) thermo-lattice Boltzmann (TLBE) approach to turbulence, and (3) phase space techniques in gyro-resonance problems in collaboration with Dieter Sigmar (MIT), Sergei Krasheninnikov (MIT), Linda Vahala (ODU), Joseph Morrison (AS and M/NASA-Langley), Pavol Pavlo and Josef Preinhaelter (institute of Plasma Physics, Czech Academy of Sciences) and Allan Kaufman (LBL/U.C.Berkeley). Using a 2-equation compressible closure model with a 2D mean flow, the authors are investigating the effects of 3D neutral turbulence on reducing the heat load to the divertor plate by various toroidal cavity geometries. These studies are being extended to examine 3D mean flows. Thermal Lattice Boltzmann (TLBE) methods are being investigated to handle 3D turbulent flows in nontrivial geometries. It is planned to couple the TLBE collisional regime to the weakly collisional regime and so be able to tackle divertor physics. In the application of phase space techniques to minority-ion RF heating, resonance heating is treated as a multi-stage process. A generalization of the Case-van Kampen analysis is presented for multi-dimensional non-uniform plasmas. Effects such as particle trapping and the ray propagation dynamics in tokamak geometry can now be handled using Weyl calculus

The main subject of research was the physics of matter at energy densities greater than 0.15 GeV/fm 3 . Theory encompasses the relativistic many-body/quantum field theory aspects of QCD and the electroweak interactions at these high energy densities, both in and out of thermal equilibrium. Applications range from neutron stars/pulsars to QCD and electroweak phase transitions in the early universe, from baryon number violation in cosmology to the description of nucleus-nucleus collisions at CERN and at Brookhaven. Recent activity to understand the properties of matter at energy densities where the electroweak W and Z boson degrees of freedom are important is reported. This problem has applications to cosmology and has the potential to explain the baryon asymmetry produced in the big bang at energies where the particle degrees of freedom will soon be experimentally, probed. This problem is interesting for nuclear physics because of the techniques used in many-body, physics of nuclei and the quark-gluon plasma may be extended to this new problem. The was also interested in problems related to multiparticle production. This includes work on production of particles in heavy-ion collisions, the small x part, of the nuclear and hadron wave function, and multiparticle production induced by instantons in weakly coupled theories. These problems have applications in the heavy ion program at RHIC and the deep inelastic scattering experiments at HERA
A modern course in statistical physics
Reichl, Linda E
2016-01-01
"A Modern Course in Statistical Physics" is a textbook that illustrates the foundations of equilibrium and non-equilibrium statistical physics, and the universal nature of thermodynamic processes, from the point of view of contemporary research problems. The book treats such diverse topics as the microscopic theory of critical phenomena, superfluid dynamics, quantum conductance, light scattering, transport processes, and dissipative structures, all in the framework of the foundations of statistical physics and thermodynamics. It shows the quantum origins of problems in classical statistical physics. One focus of the book is fluctuations that occur due to the discrete nature of matter, a topic of growing importance for nanometer scale physics and biophysics. Another focus concerns classical and quantum phase transitions, in both monatomic and mixed particle systems. This fourth edition extends the range of topics considered to include, for example, entropic forces, electrochemical processes in biological syste...

As the three-year period FY93-FY96 ended, there were six senior investigators on the grant full-time: Bulgac, Henley, Miller, Savage, van Kolck and Wilets. This represents an increase of two members from the previous three-year period, achieved with only a two percent increase over the budget for FY90-FY93. In addition, the permanent staff of the Institute for Nuclear Theory (George Bertsch, Wick Haxton, and David Kaplan) continued to be intimately associated with our physics research efforts. Aurel Bulgac joined the Group in September, 1993 as an assistant professor, with promotion requested by the Department and College of Arts and Sciences by September, 1997. Martin Savage, who was at Carnegie-Mellon University, jointed the Physics Department in September, 1996. U. van Kolck continued as research assistant professor, and we were supporting one postdoctoral research associate, Vesteinn Thorssen, who joined us in September, 1995. Seven graduate students were being supported by the Grant (Chuan-Tsung Chan, Michael Fosmire, William Hazelton, Jon Karakowski, Jeffrey Thompson, James Walden and Mitchell Watrous)

This textbook offers a clear and comprehensive introduction to analytical mechanics, one of the core components of undergraduate physics courses.It follows on naturally from the previous volumes in this series, thus expanding the knowledge in classical mechanics. The book starts with a thorough introduction into Lagrangian mechanics, detailing the d’Alembert principle, Hamilton’s principle and conservation laws. It continues with an in-depth explanation of Hamiltonian mechanics, illustrated by canonical and Legendre transformation, the generalization to quantum mechanics through Poisson brackets and all relevant variational principles. Finally, the Hamilton-Jacobi theory and the transition to wave mechanics are presented in detail. Ideally suited to undergraduate students with some grounding in classical mechanics, the book is enhanced throughout with learning features such as boxed inserts and chapter summaries, with key mathematical derivations highlighted to aid understanding. The text is supported by ...

Shirkov, D.V.
1992-02-01
A very simple and general approach to the symmetry that is widely known as a Renormalization Group symmetry is presented. It essentially uses a functional formulation of group transformations that can be considered as a generalization of self-similarity transformations well known in mathematical physics since last century. This generalized Functional Self-Similarity symmetry and corresponding group transformations are discussed first for a number of simple physical problems taken from diverse fields of classical physics as well as for QED. Then we formulate the Renorm-Group Method as a regular procedure that essentially improves the approximate solutions near the singularity. After that we discuss relations between different formulations of Renormalization Group as they appear in various parts of a modern theoretical physics. Finally we present several topics of RGM application in modern QFT. (author)

2007-01-01
This concise treatment embraces, in four parts, all the main aspects of theoretical physics (I . Mechanics and Basic Relativity, II. Electrodynamics and Aspects of Optics, III. Non-relativistic Quantum Mechanics, IV. Thermodynamics and Statistical Physics). It summarizes the material that every graduate student, physicist working in industry, or physics teacher should master during his or her degree course. It thus serves both as an excellent revision and preparation tool, and as a convenient reference source, covering the whole of theoretical physics. It may also be successfully employed to deepen its readers' insight and add new dimensions to their understanding of these fundamental concepts. Recent topics such as holography and quantum cryptography are included, thus making this a unique contribution to the learning material for theoretical physics.

Observation, experiment and hypothesis in modern physical science
Hannaway, Owen
1985-01-01
These original contributions by philosophers and historians of science discuss a range of issues pertaining to the testing of hypotheses in modern physics by observation and experiment. Chapters by Lawrence Sklar, Dudley Shapere, Richard Boyd, R. C. Jeffrey, Peter Achinstein, and Ronald Laymon explore general philosophical themes with applications to modern physics and astrophysics. The themes include the nature of the hypothetico-deductive method, the concept of observation and the validity of the theoretical-observation distinction, the probabilistic basis of confirmation, and the testing of idealizations and approximations.The remaining four chapters focus on the history of particular twentieth-century experiments, the instruments and techniques utilized, and the hypotheses they were designed to test. Peter Galison reviews the development of the bubble chamber; Roger Stuewer recounts a sharp dispute between physicists in Cambridge and Vienna over the interpretation of artificial disintegration experiments;...

Research activity of the Department of the Theoretical Physics spans a wide variety of problems in theoretical high-energy and elementary particle physics, theoretical nuclear physics, theory of the nuclear matter, quark gluon plasma and relativistic heavy-ion collisions, theoretical astrophysics, as well as general physics. Theoretical research in high energy and elementary particle physics is concentrated on the theory of deep inelastic lepton scattering in the region of low x and its phenomenological implication for the ep collider HERA at DESY, on the theory of nonleptonic decays of hadrons, and on low energy {pi}{pi} and K-anti-K interactions and scalar meson spectroscopy. The activity in the theory of relativistic heavy-ion collisions is focused on the study of quark condensate fluctuations, on the analysis of critical scattering near the chiral phase transition, and on Bose-Einstein correlation in heavy-ion collisions. Theoretical studies in nuclear physics and in theory of nuclear matter concern analysis of models, with dynamical symmetry based on group S{sub p}(6,R) for the description of collective modes of atomic nuclei, analysis of the Goldstone bosons in nuclear matter and analysis of saturation properties of nuclear matter. Research in theoretical astrophysics is mainly devoted to the analysis of magnetic properties of hadronic matter in neutron stars with proton admixture. Studies in general physics concern problem related to the Galilean covariance of classical and quantum mechanics. The detailed results obtained in various fields are summarised in presented abstracts as well as information about employed personnel, publications, contribution to conferences, reports, workshops and seminars.

The activity in the theory of relativistic heavy-ion collisions is focused on the study of quark condensate fluctuations, on the analysis of critical scattering near the chiral phase transition, and on Bose-Einstein correlation in heavy-ion collisions. Theoretical studies in nuclear physics and in theory of nuclear matter concern analysis of models, with dynamical symmetry based on group S p (6,R) for the description of collective modes of atomic nuclei, analysis of the Goldstone bosons in nuclear matter and analysis of saturation properties of nuclear matter. Research in theoretical astrophysics is mainly devoted to the analysis of magnetic properties of hadronic matter in neutron stars with proton admixture. Studies in general physics concern problem related to the Galilean covariance of classical and quantum mechanics. The detailed results obtained in various fields are summarised in presented abstracts as well as information about employed personnel, publications, contribution to conferences, reports, workshops and seminars
Constituting objectivity: Transcendental perspectives on modern physics
Everett, Jonathan
2012-05-01
There is increasing interest in exploring Kantian approaches in the study of the history and philosophy of physics. The most well-known examples of this trend-Friedman's (2001), Ryckman's (2005) and DiSalle's (2006)-focus on Kantianism in the context of the development of the general theory of relativity. The edited collection Constituting Objectivity seeks to develop key Kantian insights-in the most part-in the context of later developments in physics: as well as discussing relativity the volume also provides Kantian interpretations of Bohr's development of quantum theory and continues to provide Kantian insight from later interpretations of quantum mechanics all the way through to considering noncommutative geometry and loop quantum gravity. The volume contains papers on a wide variety of subjects and offers an essential introduction to the breadth of Kantian trends in modern physics.

From Newton to Mandelbrot a primer in theoretical physics
Stauffer, Dietrich; Lesne, Annick
2017-01-01
This textbook takes the reader on a tour of the most important landmarks of theoretical physics: classical, quantum, and statistical mechanics, relativity, electrodynamics, as well as the most modern and exciting of all: elementary particles and the physics of fractals. The second edition has been supplemented with a new chapter devoted to concise though complete presentation of dynamical systems, bifurcations and chaos theory. The treatment is confined to the essentials of each area, presenting all the central concepts and equations at an accessible level. Chapters 1 to 4 contain the standard material of courses in theoretical physics and are supposed to accompany lectures at the university; thus they are rather condensed. They are supposed to fill one year of teaching. Chapters 5 and 6, in contrast, are written less condensed since this material may not be part of standard lectures and thus could be studied without the help of a university teacher. An appendix on elementary particles lies somewhere in betwe...
On modern needs in nuclear physics and nuclear safety education
International Nuclear Information System (INIS)
Tom Loennroth
2005-01-01
The teaching of nuclear physics has a long history, particularly after the second world war, and the present author has 20 years of experience of teaching in that field. The research in nuclear physics has made major advances over the years, and the experiments become increasingly sophisticated. However, very often the university literature lags the development, as is, indeed, the case in all physics education. As a remedy of to-day, the didactic aspects are emphasized, especially at a basic level, while the curriculum content is. still left without upgrade. A standard textbook in basic nuclear physics is, while represent more modern theoretical treatises. The latter two, as their headings indicate, do not treat experimental methods, whereas has a presentation that illustrates methods and results with figures and references. However, they are from the 60 s and 70 s, they are old, and therefore cannot attract modern students of today. Consequently, one has the inevitable feeling that modern university teaching in nuclear physics, and the related area of nuclear safety, must be upgraded. A recent report in Finland, concluded that there is not sufficient nuclear safety education, but that on the other hand, it does not necessarily have to be connected with nuclear physics education, although this is recommendable. Further, the present Finnish university law states that 'The mission of the university shall be to promote free research and scientific and artistic education, to provide higher education based on research, and. to educate students to serve their country and humanity. In carrying out their mission, the universities shall interact with the surrounding society and promote the societal impact o research finding and artistic activities'. This mismatch between the curricula and the required 'societal impact' will be discussed, and examples of implications, usually not implemented, will be given. For nuclear physics specifically, the (lack of) connection between
Development of quantum perspectives in modern physics
Directory of Open Access Journals (Sweden)
Charles Baily
2009-03-01
Full Text Available Introductory undergraduate courses in classical physics stress a perspective that can be characterized as realist; from this perspective, all physical properties of a classical system can be simultaneously specified and thus determined at all future times. Such a perspective can be problematic for introductory quantum physics students, who must develop new perspectives in order to properly interpret what it means to have knowledge of quantum systems. We document this evolution in student thinking in part through pre- and post-instruction evaluations using the Colorado Learning Attitudes about Science Survey. We further characterize variations in student epistemic and ontological commitments by examining responses to two essay questions, coupled with responses to supplemental quantum attitude statements. We find that, after instruction in modern physics, many students are still exhibiting a realist perspective in contexts where a quantum-mechanical perspective is needed. We further find that this effect can be significantly influenced by instruction, where we observe variations for courses with differing learning goals. We also note that students generally do not employ either a realist or a quantum perspective in a consistent manner.

From Special Relativity to Feynman Diagrams A Course of Theoretical Particle Physics for Beginners
D'Auria, Riccardo
2012-01-01
This books aims at filling a gap between the basics courses of classical and quantum mechanics and advanced courses of (relativistic) quantum mechanics and field theory. Particular emphasis is given to the role of symmetry in modern theoretical physics. For this reason this book is particularly suited to those students who are interested in a deeper knowledge of modern developments in elementary particle physics and relativity, even if they choose not to specialize in this branch of research. This target of readers includes, besides experimental and applied physicists, also those engineers who need advanced notions of theoretical high energy physics, in view of future research activity in the field theory approach to condensed matter, in accelerator physics and in all those modern technology sectors which require a more advanced and sophisticated theoretical physics background. Courses motivated by these objectives are present in several polytechnic institutes around the world. The last chapters of this book,...
Farewell to reality how modern physics has betrayed the search for scientific truth
Baggott, Jim
2013-01-01
From acclaimed science author Jim Baggott, a pointed critique of modern theoretical physics. In this stunning new volume, Jim Baggott argues that there is no observational or experimental evidence for many of the ideas of modern theoretical physics: super-symmetric particles,super strings, the multiverse, the holographic principle,or the anthropic cosmological principle. These theories are not only untrue, it is not even science. It is fairy-tale physics: fantastical, bizarre and often outrageous, perhaps even confidence-trickery. This book provides a much-needed antidote. Informed,comprehensive, and balanced, it offers lay readers the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy. With its engaging portraits of many central figures of modern physics, including Paul Davies, John Barrow, Brian Greene, Stephen Hawking, and Leonard Susskind, it promises to be essential reading for all readers interested in what we know and don’t know about the nature of...

Research in theoretical nuclear physics: Progress report
International Nuclear Information System (INIS)
1988-08-01
In April 1988 we, along with the nuclear theory groups of Brookhaven and MIT, submitted a proposal to the Department of Energy for a national Institute of Theoretical Nuclear Physics. The primary areas of investigation proposed for this Institute are: Strong Interaction Physics--including (1) The physics of hadrons, (2) QCD and the nucleus, (3) QCD at finite temperatures and high density; nuclear astrophysics; nuclear structure and nuclear many-body theory; and nuclear tests of fundamental interactions. It is, of course, no coincidence that these are the main areas of activity of the three groups involved in this proposal and of our group in particular. Here, we will organize an outline of the progress made at Stony Brook during the past year along these lines. These four areas do not cover all of the activities of our group

Surface physics theoretical models and experimental methods
Mamonova, Marina V; Prudnikova, I A
2016-01-01
The demands of production, such as thin films in microelectronics, rely on consideration of factors influencing the interaction of dissimilar materials that make contact with their surfaces. Bond formation between surface layers of dissimilar condensed solids-termed adhesion-depends on the nature of the contacting bodies. Thus, it is necessary to determine the characteristics of adhesion interaction of different materials from both applied and fundamental perspectives of surface phenomena. Given the difficulty in obtaining reliable experimental values of the adhesion strength of coatings, the theoretical approach to determining adhesion characteristics becomes more important. Surface Physics: Theoretical Models and Experimental Methods presents straightforward and efficient approaches and methods developed by the authors that enable the calculation of surface and adhesion characteristics for a wide range of materials: metals, alloys, semiconductors, and complex compounds. The authors compare results from the ...

Physical Education between the social project of solid modernity and the of liquid modernity
Directory of Open Access Journals (Sweden)
Sidinei Pithan da Silva
2012-09-01
Full Text Available Grounded on Bauman’s thought, the present paper focuses on the constitution of social legitimacy and identity of Physical Education in the context of transition from solid to liquid modernity. This thought favors the understanding of the nature of the crisis that has crossed the identity discourse of Physical Education. The text signals the limits and possibilities of both the modern and the post-modern educational discourses. In this context, it describes a modern scenario that is marked by two distinct moments, the one of modernity at its solid stage, and that of modernity at its liquid stage. The first one, of solid modernity, social condition of surveillance, rationalization and control, performs the functional / adaptive role of putting everyone under the same rigid order (managed society. The second one, of liquid modernity, of the social condition of insignificance and irrationalism, plays the functional role of putting and keeping everyone under the same flexible Market disorder. From the scientific, mechanic focus of both the body and the physical education in solid modernity we have moved to the relativist and esthetic focus of body and physical education in liquid modernity.

Discrete or continuous? the quest for fundamental length in modern physics
Hagar, Amit
2014-01-01
The idea of infinity plays a crucial role in our understanding of the universe, with the infinite spacetime continuum perhaps the best-known example - but is spacetime really continuous? Throughout the history of science, many have felt that the continuum model is an unphysical idealization, and that spacetime should be thought of as 'quantized' at the smallest of scales. Combining novel conceptual analysis, a fresh historical perspective, and concrete physical examples, this unique book tells the story of the search for the fundamental unit of length in modern physics, from early classical electrodynamics to current approaches to quantum gravity. Novel philosophical theses, with direct implications for theoretical physics research, are presented and defended in an accessible format that avoids complex mathematics. Blending history, philosophy, and theoretical physics, this refreshing outlook on the nature of spacetime sheds light on one of the most thought-provoking topics in modern physics.

A unified grand tour of theoretical physics
Griffiths, J
2002-01-01
Anyone offering a grand tour is faced with several options. Should they concentrate on what may be considered to be essential features, or should they attempt to present a brief glimpse of almost everything? The present offering is a compromise between these two extremes. The area considered - theoretical physics - is now such a vast subject that some kind of compromise is essential. Indeed, the field is now so wide that few could even attempt to review it in a single-authored work. My task here is to assess how well this book has succeeded in its main aim of providing a unified (though introductory) tour of this subject. Constrained within a single volume, this is clearly not an updated Landau-Lifschitz. It cannot be expected to take any particular topic to the level of recent research. Nevertheless, it does seem to cover the broad range of essential topics which now constitute the subject. It starts (most appropriately in my opinion) with geometry. It then covers classical physics, general relativity and qu...
Adenine and 2-aminopurine: paradigms of modern theoretical photochemistry.
Serrano-Andrés, Luis; Merchán, Manuela; Borin, Antonio C
2006-06-06
Distinct photophysical behavior of nucleobase adenine and its constitutional isomer, 2-aminopurine, has been studied by using quantum chemical methods, in particular an accurate ab initio multiconfigurational second-order perturbation theory. After light irradiation, the efficient, ultrafast energy dissipation observed for nonfluorescent 9H-adenine is explained here by the nonradiative internal conversion process taking place along a barrierless reaction path from the initially populated 1(pipi* La) excited state toward a low-lying conical intersection (CI) connected with the ground state. In contrast, the strong fluorescence recorded for 2-aminopurine at 4.0 eV with large decay lifetime is interpreted by the presence of a minimum in the 1(pipi* La) hypersurface lying below the lowest CI and the subsequent potential energy barrier required to reach the funnel to the ground state. Secondary deactivation channels were found in the two systems related to additional CIs involving the 1(pipi* Lb) and 1(npi*) states. Although in 9H-adenine a population switch between both states is proposed, in 7H-adenine this may be perturbed by a relatively larger barrier to access the 1(npi*) state, and, therefore, the 1(pipi* Lb) state becomes responsible for the weak fluorescence measured in aqueous adenine at approximately 4.5 eV. In contrast to previous models that explained fluorescence quenching in adenine, unlike in 2-aminopurine, on the basis of the vibronic coupling of the nearby 1(pipi*) and 1(npi*) states, the present results indicate that the 1(npi*) state does not contribute to the leading photophysical event and establish the prevalence of a model based on the CI concept in modern photochemistry.

Modeling Organizational Design - Applying A Formalism Model From Theoretical Physics
Directory of Open Access Journals (Sweden)
Robert Fabac
2008-06-01
Full Text Available Modern organizations are exposed to diverse external environment influences. Currently accepted concepts of organizational design take into account structure, its interaction with strategy, processes, people, etc. Organization design and planning aims to align this key organizational design variables. At the higher conceptual level, however, completely satisfactory formulation for this alignment doesn’t exist. We develop an approach originating from the application of concepts of theoretical physics to social systems. Under this approach, the allocation of organizational resources is analyzed in terms of social entropy, social free energy and social temperature. This allows us to formalize the dynamic relationship between organizational design variables. In this paper we relate this model to Galbraith's Star Model and we also suggest improvements in the procedure of the complex analytical method in organizational design.

We describe the multi-purpose Monte-Carlo event generator WHIZARD for the simulation of high-energy particle physics experiments. Besides the presentation of the general features of the program like SM physics, BSM physics, and QCD effects, special emphasis is given to the support of the most accurate simulation of the collider environments at hadron colliders and especially at future linear lepton colliders. On the more technical side, the very recent code refactoring towards a completely object-oriented software package to improve maintainability, flexibility and code development are discussed. Finally, we present ongoing work and future plans regarding higher-order corrections, more general model support including the setup to search for new physics in vector boson scattering at the LHC, as well as several lines of performance improvements.

Modern fluid dynamics for physics and astrophysics
Regev, Oded; Yecko, Philip A
2016-01-01
This book grew out of the need to provide students with a solid introduction to modern fluid dynamics. It offers a broad grounding in the underlying principles and techniques used, with some emphasis on applications in astrophysics and planetary science. The book comprehensively covers recent developments, methods and techniques, including, for example, new ideas on transitions to turbulence (via transiently growing stable linear modes), new approaches to turbulence (which remains the enigma of fluid dynamics), and the use of asymptotic approximation methods, which can give analytical or semi-analytical results and complement fully numerical treatments. The authors also briefly discuss some important considerations to be taken into account when developing a numerical code for computer simulation of fluid flows. Although the text is populated throughout with examples and problems from the field of astrophysics and planetary science, the text is eminently suitable as a general introduction to fluid dynamics. It...
Progress in particle physics and modern cosmology

Dolgov, A.D.

A review of the fundamental cosmological problems is given; possible ways of their solution are discussed. A considerable attention is paid to inflationary universe models. It is based on a single assumption that in the history of the universe a period of exponential expansion once existed. If it was sufficiently long the problems of homogeneity, isotropy, horizon, flatness, and relic monopoles could be solved in a unified manner. This is in favour of the model. Against the model is the cosmological term problem and the absence (in the meanwhile) of a consistent in detail of theoretical basis
Solid state physics principles and modern applications
Quinn, John J
2018-01-01
This book provides the basis for a two-semester graduate course on solid-state physics. The first half presents all the knowledge necessary for a one-semester survey of solid-state physics, but in greater depth than most introductory solid state physics courses. The second half includes most of the important research over the past half-century, covering both the fundamental principles and most recent advances. This new edition includes the latest developments in the treatment of strongly interacting two-dimensional electrons and discusses the generalization from small to larger systems. The book provides explanations in a class-tested tutorial style, and each chapter includes problems reviewing key concepts and calculations. The updated exercises and solutions enable students to become familiar with contemporary research activities, such as the electronic properties of massless fermions in graphene and topological insulators.

This is the third edition of a well-received textbook on modern physics theory. This book provides an elementary but rigorous and self-contained presentation of the simplest theoretical framework that will meet the needs of undergraduate students. In addition, a number of examples of relevant applications and an appropriate list of solved problems are provided.Apart from a substantial extension of the proposed problems, the new edition provides more detailed discussion on Lorentz transformations and their group properties, a deeper treatment of quantum mechanics in a central potential, and a closer comparison of statistical mechanics in classical and in quantum physics. The first part of the book is devoted to special relativity, with a particular focus on space-time relativity and relativistic kinematics. The second part deals with Schrödinger's formulation of quantum mechanics. The presentation concerns mainly one-dimensional problems, but some three-dimensional examples are discussed in detail. The third...
The Universe Untangled; Modern physics for everyone
Pillitteri, Abigail
2017-04-01
Physics has always been a tricky subject for the general public. Millions are fascinated by the laws of the physical world, but there has been a lack of books written specifically for general readers. The Universe Untangled is for those who are curious; yet do not have an extensive mathematical background. It uses images, analogies and comprehensible language to cover popular topics of interest including the evolution of the Universe, fundamental forces, the nature of space and time, and the quest for knowing the unknown.

L.V. Shuba
2017-12-01
Full Text Available Purpose : to develop and experimentally substantiate fitness technology for students taking into account their individual peculiarities. Material : The experiment was performed by girls (n=51, age 17-20 who were divided into experimental (n=25 and control (n=26 groups. Classes were held twice a week during the year: 66 hours in the hall and 95 hours of independent study. At the beginning and at the end of the study, all students met the control standards, which allowed to determine the level of development of physical qualities and level of physical fitness. Results : 8 exercise complexes were developed to implement our fitness technology. Complexes were taken into account: interests, age, individual characteristics and level of physical fitness of students. At the first lessons the loading was about 45-50%. In the future, the loading increases to 70-75% of the total time of classes. Conclusions : When constructing fitness technology using varieties of fitness it is necessary to take into account: the type and nature of exercises, the volume and intensity of exercises, the number of repetitions and the amount of weight, the frequency of training sessions and the duration of work, intervals of rest, the number and alternation of exercises.
Physics Without Physics. The Power of Information-theoretical Principles
D'Ariano, Giacomo Mauro
2017-01-01
David Finkelstein was very fond of the new information-theoretic paradigm of physics advocated by John Archibald Wheeler and Richard Feynman. Only recently, however, the paradigm has concretely shown its full power, with the derivation of quantum theory (Chiribella et al., Phys. Rev. A 84:012311, 2011; D'Ariano et al., 2017) and of free quantum field theory (D'Ariano and Perinotti, Phys. Rev. A 90:062106, 2014; Bisio et al., Phys. Rev. A 88:032301, 2013; Bisio et al., Ann. Phys. 354:244, 2015; Bisio et al., Ann. Phys. 368:177, 2016) from informational principles. The paradigm has opened for the first time the possibility of avoiding physical primitives in the axioms of the physical theory, allowing a re-foundation of the whole physics over logically solid grounds. In addition to such methodological value, the new information-theoretic derivation of quantum field theory is particularly interesting for establishing a theoretical framework for quantum gravity, with the idea of obtaining gravity itself as emergent from the quantum information processing, as also suggested by the role played by information in the holographic principle (Susskind, J. Math. Phys. 36:6377, 1995; Bousso, Rev. Mod. Phys. 74:825, 2002). In this paper I review how free quantum field theory is derived without using mechanical primitives, including space-time, special relativity, Hamiltonians, and quantization rules. The theory is simply provided by the simplest quantum algorithm encompassing a countable set of quantum systems whose network of interactions satisfies the three following simple principles: homogeneity, locality, and isotropy. The inherent discrete nature of the informational derivation leads to an extension of quantum field theory in terms of a quantum cellular automata and quantum walks. A simple heuristic argument sets the scale to the Planck one, and the currently observed regime where discreteness is not visible is the so-called "relativistic regime" of small wavevectors, which

Fearful Symmetry: The Search for Beauty in Modern Physics

It is easy to see beauty in symmetry when we look at buildings like the Taj Mahal or natural objects such as snowflakes; it is much harder to explain to a non-expert the beauty of equations or of symmetry concepts in relativity or in particle theory. Tony Zee achieves this in a remarkable way, while he also manages to make many complicated concepts accessible to a reader who is genuinely interested and who has some basic/school knowledge of physics. To do this he invents various ordinary world analogies and exploits them in a masterful way. I liked, in particular, his analogy for the colour of quarks and the associated SU(3) symmetry provided by adding colour to ice-cream, which does not change its cost. Of course, sometimes real beauty is associated with a small breakdown of symmetry. We are all familiar with this in music or in art. Tony shows that such a breakdown also has a role in physics and that it is often associated with unexpected and very deep and important concepts (parity, CP violation or baryon assymetry). The book is an amazing achievement; although the main focus is on symmetry and beauty the author manages to explain most of the new and relevant concepts of modern physics, from quantum mechanics and relativity to superstrings and superbranes. And he does this with no equations and almost no mathematical symbols. So who is this book intended for? Who will enjoy reading it? Clearly, it will be appreciated by all theoretical physicists, who probably will be primarily impressed by the way the book makes accessible so many very difficult concepts. I was particularly struck by Tony's ability to explain things in simple terms and to find relevant analogies. It will be also greatly enjoyed by the non-specialist but 'interested' reader; (s)he may find some concepts hard to follow but (s)he will get the general gist of the arguments. It will be also be enjoyed by sixth-formers studying physics and quite possibly will attract some of them to

Theoretical physics is the first step for the development of science and technology. For more than 100 years it has delivered new and sophisticated discoveries which have changed human views of their surroundings and universe. Theoretical physics has also revealed that the governing law in our universe is not deterministic, and it is undoubtedly the foundation of our modern civilization. Contrary to its importance, research in theoretical physics is not well advanced in some developing countries such as Indonesia. This workshop provides the formal meeting in Indonesia devoted to the field of theoretical physics and is organized to cover all subjects of theoretical physics as well as nonlinear phenomena in order to create a gathering place for the theorists in Indonesia and surrounding countries, to motivate young physicists to keep doing active researches in the field and to encourage constructive communication among the community members. Following the success of the tenth previous meetings in this conference series, the eleventh conference was held in Sebelas Maret University (UNS), Surakarta, Indonesia on 15 February 2014. In addition, the conference was proceeded by School of Advance Physics at Gadjah Mada University (UGM), Yogyakarta, on 16-17 February 2014. The conference is expected to provide distinguished experts and students from various research fields of theoretical physics and nonlinear phenomena in Indonesia as well as from other continents the opportunities to present their works and to enhance contacts among them. The introduction to the conference is continued in the pdf.

DIFFICULTIES TO LEARN AND TO TEACH MODERN PHYSICS.
Directory of Open Access Journals (Sweden)
R. Antonowiski
2017-08-01
Full Text Available Physics is engaged in scientific and technological development in several areas, however, its learning in high school has high failure rates that demonstrate a low level of use. It is a science that allows us to understand the nature of the macroscopic and atomic matter, but it is taught in a disjointed manner, upon presentation of concepts, laws and mathematical sentences, repetitive exercises that have taken the preparatory character for college entrance. Thus, the student gets stuck sentences featuring a partial knowledge and disposable. This study aimed to analyze the main difficulties that undergraduate students in Physics have in Modern Physics learning. Point out the difficulties in teaching and learning Physics is not an easy task and to identify them comes the difficulty of how to solve them. After analysis of several hypotheses we can conclude that there is no single factor responsible for the difficulty of the teaching and learning of Modern Physics. The lack of time to work and developed since middle school, stimulating the curiosity of students, adequately trained teachers, lack of structure offered by the government, parents' responsibilities and students in learning, among others, constitute a major challenge for successful teaching and learning of Modern Physics
Physics for Scientists and Engineers with Modern Physics
Fishbane, Paul M; Thornton, Stephen T
2005-01-01
This text is designed for a calculus-based physics course at the beginning university and college level. It is written with the expectation that students have either taken or are currently taking a beginning course in calculus. Students taking a physics course based on this book should leave with a solid conceptual understanding of the fundamental physical laws and how these laws can be applied to solve many problems. The key word for this edition is "understanding." The third edition of this text remains rigorous while including a number of new pedagogical elements which emphasize conceptual understanding.

Gender and Physics: a Theoretical Analysis

This article argues that the objections raised by Koertge (1998), Gross and Levitt (1994), and Weinberg (1996) against feminist scholarship on gender and physics are unwarranted. The objections are that feminist science studies perpetuate gender stereotypes, are irrelevant to the content of physics, or promote epistemic relativism. In the first part of this article I argue that the concept of gender, as it has been developed in feminist theory, is a key to understanding why the first objection is misguided. Instead of reinforcing gender stereotypes, feminist science studies scholars can formulate empirically testable hypotheses regarding local and contested beliefs about gender. In the second part of this article I argue that a social analysis of scientific knowledge is a key to understanding why the second and the third objections are misguided. The concept of gender is relevant for understanding the social practice of physics, and the social practice of physics can be of epistemic importance. Instead of advancing epistemic relativism, feminist science studies scholars can make important contributions to a subfield of philosophy called social epistemology.

In 1995 the University of Florida started a major expansion of the High Energy Experimental Physics group (HEE) with the goal of adding four new faculty level positions to the group in two years. This proposal covers the second year of operation of the new group and gives a projection of the planned research program for the next five years, when the group expects their activities to be broader and well defined. The expansion of the HEE group started in the Fall of 1995 when Guenakh Mitselmakher was hired from Fermilab as a Full Professor. A search was then performed for two junior faculty positions. The first being a Research Scientist/Scholar position which is supported for 9 months by the University on a faculty line at the same level as Assistant Professor but without the teaching duties. The second position is that of an Assistant Professor. The search has been successfully completed and Jacobo Konigsberg from Harvard University has accepted the position of Research Scientist and Andrey Korytov from MIT has accepted the position of Assistant Professor. They will join the group in August 1996. The physics program for the new group is focused on hadron collider physics. G. Mitselmakher has been leading the CMS endcap muon project since 1994. A Korytov is the coordinator of the endcap muon chamber effort for CMS and a member of the CDF collaboration and J. Konigsberg is a member of CDF where he has participated in various physics analyses and has been coordinator of the gas calorimetry group. The group at the U. of Florida has recently been accepted as an official collaborating institution on CDF. They have been assigned the responsibility of determining the collider beam luminosity at CDF and they will also be an active participant in the design and operation of the muon detectors for the intermediate rapidity region. In addition they expect to continue their strong participation in the present and future physics analysis of the CDF data
On the co-creation of classical and modern physics.
Staley, Richard
2005-12-01
While the concept of "classical physics" has long framed our understanding of the environment from which modern physics emerged, it has consistently been read back into a period in which the physicists concerned initially considered their work in quite other terms. This essay explores the shifting currency of the rich cultural image of the classical/ modern divide by tracing empirically different uses of "classical" within the physics community from the 1890s to 1911. A study of fin-de-siècle addresses shows that the earliest general uses of the concept proved controversial. Our present understanding of the term was in large part shaped by its incorporation (in different ways) within the emerging theories of relativity and quantum theory--where the content of "classical" physics was defined by proponents of the new. Studying the diverse ways in which Boltzmann, Larmor, Poincaré, Einstein, Minkowski, and Planck invoked the term "classical" will help clarify the critical relations between physicists' research programs and their use of worldview arguments in fashioning modern physics.
Physically self-consistent basis for modern cosmology
International Nuclear Information System (INIS)
Khlopov, M.Yu.
2000-01-01
Cosmoparticle physics appeared as a natural result of internal development of cosmology seeking physical grounds for inflation, baryosynthesis, and nonbaryonic dark matter and of particle physics going outside the Standard Model of particle interactions. Its aim is to study the foundations of particle physics and cosmology and their fundamental relationship in the combination of respective indirect cosmological, astrophysical, and physical effects. The ideas on new particles and fields predicted by particle theory and on their cosmological impact are discussed, as well as the methods of cosmoparticle physics to probe these ideas, are considered with special analysis of physical mechanisms for inflation, baryosynthesis, and nonbaryonic dark matter. These mechanisms are shown to reflect the main principle of modern cosmology, putting, instead of formal parameters of cosmological models, physical processes governing the evolution of the big-bang universe. Their realization on the basis of particle theory induces additional model-dependent predictions, accessible to various methods of nonaccelerator particle physics. Probes for such predictions, with the use of astrophysical data, are the aim of cosmoarcheology studying astrophysical effects of new physics. The possibility of finding quantitatively definite relationships between cosmological and laboratory effects on the basis of cosmoparticle approach, as well as of obtaining a unique solution to the problem of physical candidates for inflation, mechanisms of baryogenesis, and multicomponent dark matter, is exemplified in terms of gauge model with broken family symmetry, underlying horizontal unification and possessing quantitatively definite physical grounds for inflation, baryosynthesis, and effectively multicomponent dark-matter scenarios

This report describes research supported by the US Dept. of Energy Office of High Energy Physics (OHEP), performed by the UCLA Particle Beam Physics Laboratory (PBPL). The UCLA PBPL has, over the last two decades-plus, played a critical role in the development of advanced accelerators, fundamental beam physics, and new applications enabled by these thrusts, such as new types of accelerator-based light sources. As the PBPL mission is broad it is natural that it has been grown within the context of the accelerator science and technology stewardship of the OHEP. Indeed, steady OHEP support for the program has always been central to the success of the PBPL; it has provided stability, and above all has set the over-arching themes for our research directions, which have producing over 500 publications (>120 in high level journals). While other agency support has grown notably in recent years, permitting more vigorous pursuit of the program, it is transient by comparison. Beyond permitting program growth in a time of flat OHEP budgets, the influence of other agency missions is found in push to adapt advanced accelerator methods to applications, in light of the success the field has had in proof-of-principle experiments supported first by the DoE OHEP. This three-pronged PBPL program — advanced accelerators, fundamental beam physics and technology, and revolutionary applications — has produced a generation of students that have had a profound affect on the US accelerator physics community. PBPL graduates, numbering 28 in total, form a significant population group in the accelerator community, playing key roles as university faculty, scientific leaders in national labs (two have been named Panofsky Fellows at SLAC), and vigorous proponents of industrial application of accelerators. Indeed, the development of advanced RF, optical and magnet technology at the PBPL has led directly to the spin-off company, RadiaBeam Technologies, now a leading industrial accelerator firm

Full Text Available After more than two decades of justifications on the insertion of Modern and Contemporary Physics in the high school Education, the current challenge regards to how this content can be inserted in the classroom in an interesting and innovative way. Recent research reveals that despite a significant accumulation of recent academic research, whose purpose is to assist teachers pedagogically, few are grounded and proposed theoretically seeking to investigate how this integration happens. In this sense, we present a teaching-learning sequence on the topic of radioactivity, forged in the theoretical and methodological assumptions of Design-Based Research and a Teaching-Learning Sequence that, when implemented in public schools in the south of Bahia, produced the relevant knowledge to be shared with the community on teaching physics. Forged in our assumptions, the proposal allows teachers and researchers to understand questions about how, when and why, in fact, the inclusion of Modern and Contemporary Physics can occur in a non-traditional way. Therefore, the importance of this proposal is revealed to the high school of physics as it translates its ability to transform the theoretical demands on the curriculum and methodological innovation in the practical interventions in the classroom. We add that the availability of the necessary sources to find lesson plans, quizzes, texts, videos of teaching-learning sequence, shows the contribution of this work for teachers and researchers, in particular, to improve the scientific learning of students in the Basic Education.

Nolting, Wolfgang
2017-01-01
This concise textbook offers a clear and comprehensive introduction to special relativity, one of the core components of undergraduate physics courses. It follows on naturally from the previous volumes in this series, thus developing the relativistic expansion of classical mechanics and electrodynamics. The first part of the book introduces Lorentz transformations, time dilation, length contraction and Minkowski diagrams. More complex themes are covered in the second part of the book, which describes the four-dimensional covariant formulation for classical mechanics and electrodynamics, including discussion of Maxwell’s equations, the Lorentz force and the covariant Lagrangian formulation. Ideally suited to undergraduate students with some grounding in classical mechanics and electrodynamics, the book is enhanced throughout with learning features such as boxed inserts and chapter summaries, with key mathematical derivations highlighted to aid understanding. The text is supported by numerous worked examples ...

The paper examines how experimental High Energy Physics can use modern computer architectures efficiently. In this connection parallel and vector architectures are investigated, and the types available at the moment for general use are discussed. A separate section briefly describes some architectures that are either a combination of both, or exemplify other architectures. In an appendix some directions in which computing seems to be developing in the USA are mentioned. (author)
Theoretical high energy and nuclear physics
International Nuclear Information System (INIS)
1986-01-01
Motivated by the fact that the non-cancellation of infrared divergences in QCD can be avoided by using soft degenerate states or coherent states in the initial state, it is proposed that the partons be identified with nearly degenerate, coherent quark-gluon ''jet'' states. An investigation is discussed of whether a ''jet'' based factorization, which occurs at higher twist, is a natural property of QCD and whether it maintains the universality of mass singularities and the factorization of QCD processes ito short-distance and long-distance parts. The coherent state operator exponentiation theorem is used to incorporate spectator interactions in order to develop a Hamiltonian approach to analyze rearrangement effects in hadronic collisions. The relationships among this operator exponentiation, the higher twist ''quasi-partonic operators,'' and the non-abelian eikonal-exponentiation theorem are being examined. Using methods developed for QCD, exploratory investigations are being made of the infrared structure of some supersymmetric and superstring theories. In a second program, because of the successul applications of the phi phi symmetry test by the Mark III collaboration, fundamental tests are being devised which can be used to probe discrete symmetries, and their possible violations, in the required ''new physics'' beyond the standard model. Using the helicity formulation for three-body decays, the sequential decay H → anti f 1 f 2 are analyzed where anti f 1 f 2 are an antilepton-lepton pair or an antiquaark-quark pair. 47 refs

Applied Mathematical Methods in Theoretical Physics
Masujima, Michio
2005-04-01
All there is to know about functional analysis, integral equations and calculus of variations in a single volume. This advanced textbook is divided into two parts: The first on integral equations and the second on the calculus of variations. It begins with a short introduction to functional analysis, including a short review of complex analysis, before continuing a systematic discussion of different types of equations, such as Volterra integral equations, singular integral equations of Cauchy type, integral equations of the Fredholm type, with a special emphasis on Wiener-Hopf integral equations and Wiener-Hopf sum equations. After a few remarks on the historical development, the second part starts with an introduction to the calculus of variations and the relationship between integral equations and applications of the calculus of variations. It further covers applications of the calculus of variations developed in the second half of the 20th century in the fields of quantum mechanics, quantum statistical mechanics and quantum field theory. Throughout the book, the author presents over 150 problems and exercises -- many from such branches of physics as quantum mechanics, quantum statistical mechanics, and quantum field theory -- together with outlines of the solutions in each case. Detailed solutions are given, supplementing the materials discussed in the main text, allowing problems to be solved making direct use of the method illustrated. The original references are given for difficult problems. The result is complete coverage of the mathematical tools and techniques used by physicists and applied mathematicians Intended for senior undergraduates and first-year graduates in science and engineering, this is equally useful as a reference and self-study guide.

We are carrying out a research program in high energy experimental particle physics. Studies of high energy hadronic interactions and leptoproduction processes continue using several experimental techniques. Progress has been made on the study of multiparticle production processes in nuclei. Ultra-high energy cosmic ray nucleus-nucleus interactions have been investigated by the Japanese American Cosmic Emulsion Experiment (JACEE) using balloon-borne emulsion chamber detectors. In the area of particle astrophysics, our studies of cosmic ray nuclear interactions have enabled us to make the world's most accurate determination of the composition of the cosmic rays above 10 13 eV. We have the only detector that can observe interaction vertices and identify particles at energies up to 10--15 eV. Our observations are getting close to placing limits on the acceleration mechanisms postulated for pulsars in which the spin and magnetic moment axes are at different angles. In June, 1989 approval was given by NASA for our participation in the Space Station program. The SCINATT experiment will make use of emulsion chamber detectors, similar to the planned JACEE hybrid balloon flight detectors. These detectors will permit precise determination of secondary particle charges, momenta and rapidities, and the accumulation of data will be at least a factor of 10 to 100 greater than in balloon experiments. Emulsion chamber techniques are also employed in an experiment using accelerator heavy ion beams at CERN and Brookhaven National Laboratory to investigate particle production processes in central collisions of nuclei in the energy range 15--200A GeV. Our study of hadroproduction in lepton interactions is continuing with approval of another 8 months run for deep inelastic muon scattering experiment E665 at Fermilab
Theoretical studies in hadronic and nuclear physics

Griffin, J.J.; Cohen, T.D.

Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. The section on Hadrons in Nuclei reports research into the ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. QCD sum rules supply a new insight into the decrease of the nucleon's mass in the nuclear medium. The quark condensate decreases in nuclear matter, and this is responsible for the decrease of the nucleon's mass. The section on the Structure of Hadrons reports progress in understanding the structure of the nucleon. These results cover widely different approaches -- lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. Progress in Relativistic Nuclear Physics is reported on electromagnetic interactions in a relativistic bound state formalism, with applications to elastic electron scattering by deuterium, and on application of a two-body quasipotential equation to calculate the spectrum of mesons formed as bound states of a quark and antiquark. A Lorentz-invariant description of the nuclear force suggests a decrease of the nucleon's mass in the nuclear medium similar to that found from QCD sum rules. Calculations of three-body bound states with simple forms of relativistic dynamics are also discussed. The section on Heavy Ion Dynamics and Related Processes describes progress on the (e + e - ) problem and heavy-on dynamics. In particular, the sharp electrons observed in β + irradiation of heavy atoms have recently been subsumed into the ''Composite Particle Scenario,'' generalizing the ''(e + e - -Puzzle'' of the pairs from heavy ion collisions to the ''Sharp Lepton Problem.''

The theoretical minimum what you need to know to start doing physics
Susskind, Leonard
2013-01-01
In this unconventional and stimulating primer, world-class physicist Leonard Susskind and citizen-scientist George Hrabovsky combine forces to provide a brilliant first course in modern physics. Unlike most popular physics books - which give readers a taste of what physicists know but not what they actually do - Susskind and Hrabovsky teach the skills you need to do physics yourself. Combining crystal-clear explanations of the laws of the universe with basic exercises, the authors cover the minimum - the theoretical minimum of the title - that readers need to master in order to study more advanced topics. In a lucid, engaging style, they introduce all the key concepts, from classical mechanics to general relativity to quantum theory. Instead of shying away from the equations and maths that are essential to any understanding of physics, The Theoretical Minimum provides a toolkit that you won't find in any other popular science book.
The world-line. Albert Einstein and modern physics
International Nuclear Information System (INIS)
Maalampi, Jukka
2008-01-01
This book is an entertaining and formula-free presentation of modern physics from the 19th century to present. The life of Albert Einstein and his scientific works are drawn as red fathom through the text. The author explains central terms and results of modern physics in populary-scientific form from the historical perspective. To the reader in humorous form an imagination is mediated how modern physics has been developed. We learn from the exciting effects of the ether, we hear from faraday and magnetic needles, from Maxwell's prediction of the electromagnetic waves, from heinrich Hertz and from the photoelectric effect. Was the Michelson-Morley experiment a measurement success or an unsuccess? Why has Einstein abandoned the ether? How has Einstein in the miraculous year 1905 revolutionated physics and why he has begged Newton for excusement? Exist atoms? What is motion? What is light and what is to be understood under ''now'' and ''here''? Light deviation or non-deviation? How act the tidal forces? And above all: How has Einstein answered these questions. We meet Poincare, Lorentz and Hilbert, Boltzmann and Bohr, Minkowski, Planck, de Broglie, Hubble and Weyl, Gamow, Hahn and Meitner, Kapiza and Landau, Fermi and many other famous scientists. What had Eddington against Chandrasekhar and what had Einstein against black holes? Why should space tourists and dream tourists make holiday not on the Loch Ness but on the safe side of a black hole? Why inveighed Pauli against Einstein? Is the concern with the atomic-bomb formula right? Smeared matter, big bang and cosmic background radiation, gravitational waves and double pulsars, the cosmological constant and the expansion of the universe are further themes, which keep the reader in breath and let no mental vacuum arise [de
Handbook of Modern Sensors Physics, Designs, and Applications
Fraden, Jacob
2010-01-01
This book is about devices commonly called sensors. Digital systems, however complex and intelligent they might be, must receive information from the outside world that is generally analog and not electrical. Sensors are interface devices between various physical values and the electronic circuits who "understand" only a language of moving electrical charges. In other words, sensors are the eyes, ears, and noses of silicon chips. Unlike other books on sensors, this book is organized according to the measured variables (temperature, pressure, position, etc.) that make it much more practical and easier to read. In this new edition recent ideas and developments have been added while less important and non-essential designs were dropped. Sections on practical designs and use of the modern micro-machining technologies have been revised substantially. This book is a reference text that can be used by students, researchers interested in modern instrumentation (applied physicists and engineers), sensor designers, app...
THE PHYSICS OF MELTING IN EARLY MODERN LOVE POETRY
Directory of Open Access Journals (Sweden)
Andrea Brady
2014-12-01
Full Text Available Melting is a familiar trope in early modern erotic poetry, where it can signify the desire to transform the beloved from icy chastity through the warmth of the lover’s passion. However, this Petrarchan convention can be defamiliarised by thinking about the experiences of freezing and melting in this period. Examining melting in the discourses of early modern meteorology, medicine, proverb, scientific experiments, and preservative technologies, as well as weather of the Little Ice Age and the exploration of frozen hinterlands, this essay shows that our understanding of seeming constants – whether they be the physical properties of water or the passions of love – can be modulated through attention to the specific histories of cognition and of embodiment.

Full Text Available Purpose: significant increase of students’ physical condition and health level at the account of application of modern power cardio training methodic. Material: 120 students (60 boys and 60 girls participated in the research. The age of the tested was 19 years. The research took one year. We used methodic of power and functional impact on trainees’ organism (HOT IRON. Such methodic is some systems of physical exercises with weights (mini-barbells, to be fulfilled under accompaniment of specially selected music. Results: we showed advantages of power-cardio and fitness trainings in students’ health improvement and in elimination obesity. Control tests showed experimental group students achieved confidently higher physical indicators. Boys demonstrated increase of physical strength and general endurance indicators. Girls had confidently better indicators of physical strength, flexibility and general endurance. Increase of control group students’ body mass can be explained by students’ insufficient physical activity at trainings, conducted as per traditional program. Conclusions: students’ trainings by power-cardio methodic with application HOT IRON exercises facilitate development the following physical qualities: strength and endurance in boys and strength, flexibility and endurance in girls. Besides, it was found that such systems of exercises facilitate normalization of boys’ body mass and correction of girls’ constitution.

Matvei Petrovich Bronstein and Soviet theoretical physics in the thirties
Gorelik, Gennady E
1994-01-01
Gennady E. Gorelik and Victor Ya. Frenkel Matvei Petrovich Bronstein and Soviet Theoretical Physics in the Thirties Translated by Valentina M. Levina The short life and tragic death of Matvei Petrovich Bronstein (1906-1938) may be seen as a symbol of the man's time and his country. One of the most remarkable features of Soviet history was the impressive advance of its physical sciences against the brutal and violent background of totalitarianism. Soviet advances in nuclear and space technology form an important part of world history. These achievements had their roots in the 1930s, when Bronstein's generation entered science. Among his friends were the famous physicists Lev Landau and George Gamow. Bronstein worked in the vast field of theoretical physics, ranging from nuclear physics to astrophysics and from relativistic quantum theory to cosmology. His pioneering work on quantizing gravitation goes beyond the history of physics, because today the quantum theory of gravitation occupies a special place in fun...
The beautiful invisible creativity, imagination, and theoretical physics
Vignale, Giovanni
2011-01-01
Challenging the image of theoretical physics as a dry discipline, The Beautiful Invisible shows that this highly abstract science is in fact teeming with beautiful concepts, and the task of imagining them demands profound creativity, just as creative as the work of poets or magical realist novelists such as Borges and Musil. "A good scientific theory is like a symbolic tale, an allegory of reality," writes Giovanni Vignale, as he uncovers the unexpected links between theoretical physics and artistic creativity. In engaging and at times poetic prose, and with ample quotations from many of the writers he admires, Vignale presents his own unorthodox accounts of fundamental theoretical concepts such as Newtonian mechanics, superconductivity, and Einstein's theory of relativity, illuminating their profound implications. Throughout, the author treats readers to glimpses of physics as "exercised in the still night, when only the moon rages." Indeed, as we delve behind now-familiar concepts such as "electron spin" an...

Actuality of transcendental æsthetics for modern physics
Petitot, Jean
1. The more mathematics and physics unify themselves in the physico-mathematical modern theories, the more an objective epistemology becomes necessary. Only such a transcendental epistemology is able to thematize correctly the status of the mathematical determination of physical reality. 2. There exists a transcendental history of the synthetic a priori and of the construction of physical categories. 3. The transcendental approach allows to supersed Wittgenstein's and Carnap's antiplatonist thesis according to which pure mathematics are physically applicable only if they lack any descriptive, cognitive or objective, content and reduce to mere prescriptive and normative devices. In fact, pure mathematics are prescriptive-normative in physics because: (i) the categories of physical objectivity are prescriptive-normative, and (ii) their categorial content is mathematically “constructed” through a Transcendental Aesthetics. Only a transcendental approach make compatible, in the one hand, a grammatical conventionalism of Wittgensteinian or Carnapian type and, on the other hand, a platonist realism of Gödelian type. Mathematics are not a grammar of the world but a mathematical hermeneutics of the intuitive forms and of the categorial grammar of the world.

Manin, Y I
2014-01-01
This paper is a survey based upon the talk at the satellite QQQ conference to ECM6, 3Quantum: Algebra Geometry Information, Tallinn, July 2012. It is dedicated to the analogy between the notions of complexity in theoretical computer science and energy in physics. This analogy is not metaphorical: I describe three precise mathematical contexts, suggested recently, in which mathematics related to (un)computability is inspired by and to a degree reproduces formalisms of statistical physics and quantum field theory.
Mathematical physics a modern introduction to its foundations
Hassani, Sadri
2013-01-01
The goal of this book is to expose the reader to the indispensable role that mathematics---often very abstract---plays in modern physics. Starting with the notion of vector spaces, the first half of the book develops topics as diverse as algebras, classical orthogonal polynomials, Fourier analysis, complex analysis, differential and integral equations, operator theory, and multi-dimensional Green's functions. The second half of the book introduces groups, manifolds, Lie groups and their representations, Clifford algebras and their representations, and fiber bundles and their applications to differential geometry and gauge theories. This second edition is a substantial revision of the first one with a complete rewriting of many chapters and the addition of new ones, including chapters on algebras, representation of Clifford algebras and spinors, fiber bundles, and gauge theories. The spirit of the first edition, namely the balance between rigor and physical application, has been maintained, as is the abundance...
Handbook of modern sensors physics, designs, and applications
Fraden, Jacob
2016-01-01
This book presents a comprehensive and up-to-date account of the theory (physical principles), design, and practical implementations of various sensors for scientific, industrial, and consumer applications. This latest edition focuses on the sensing technologies driven by the expanding use of sensors in mobile devices. These new miniature sensors will be described, with an emphasis on smart sensors which have embedded processing systems. The chapter on chemical sensors has also been expanded to present the latest developments. Digital systems, however complex and intelligent they may be, must receive information from the outside world that is generally analog and not electrical. Sensors are interface devices between various physical values and the electronic circuits that "understand" only a language of moving electrical charges. In other words, sensors are the eyes, ears, and noses of silicon chips. Unlike other books on sensors, the Handbook of Modern Sensors is organized according to the measured variables...

Mathematics is a very beautiful subject−very much an indispensible tool for Physics, more so for Theoretical Physics (by which we mean here mainly Field Theory and High Energy Physics). These branches of Physics are based on Quantum Mechanics and Special Theory of Relativity, and many mathematical concepts are used in them. In this work, we shall elucidate upon only some of them, like−differential geometry, infinite series, Mellin transforms, Fourier and integral transforms, special functions, calculus, complex algebra, topology, group theory, Riemannian geometry, functional analysis, linear algebra, operator algebra, etc. We shall also present, some physics issues, where these mathematical tools are used. It is not wrong to say that Mathematics is such a powerful tool, without which, there can not be any Physics theory!! A brief review on our research work is also presented.

What is Time in Some Modern Physics Theories: Interpretation Problems
Directory of Open Access Journals (Sweden)
Karpenko Ivan A.
2016-03-01
Full Text Available The article deals with the problem of time in the context of several theories of modem physics. This fundamental concept inevitably arises in physical theories, but so far there is no adequate description of it in the philosophy of science. In the theory of relativity, quantum field theory. Standard Model of particle physics, theory of loop quantum gravity, superstring theory and other most recent theories the idea of time is shown explicitly or not. Sometimes, such as in the special theory of relativity, it plays a significant role and sometimes it does not. But anyway it exists and is implied by the content of the theory, which in some cases directly includes its mathematical tools. Fundamental difference of space-time processes in microcosm and macrocosm is of particular importance for solving the problem. In this regard, a need to understand the time in the way it appears in modem physics, to describe it in the language of philosophy arises (satisfactory for time description mathematical tools also do not exist. This will give an opportunity to get closer to the answer on question of time characteristics. And even if we do not obtain the exact answer, we will still be able to formulate the right question about its nature. For this purpose, the present research carries out analysis of the key theories of modern physics with regard to historical and scientific, historical and philosophical perspectives, hi some cases, this gives an opportunity to detect the succession of the associated with time perception ideas, their development, as well as the origination of fundamentally new ones. During the analysis, the conect characteristics of time are formulated from the point of view of physical theory and the attempt to state the nature of time is made. On the ground of conducted research, the conclusions about current state of the problem and its future solution perspectives are drawn.

The determination of the fundamental parameters of the Standard Model (and its extensions) is often limited by the presence of statistical and theoretical uncertainties. We present several models for the latter uncertainties (random, nuisance, external) in the frequentist framework, and we derive the corresponding p values. In the case of the nuisance approach where theoretical uncertainties are modeled as biases, we highlight the important, but arbitrary, issue of the range of variation chosen for the bias parameters. We introduce the concept of adaptive p value, which is obtained by adjusting the range of variation for the bias according to the significance considered, and which allows us to tackle metrology and exclusion tests with a single and well-defined unified tool, which exhibits interesting frequentist properties. We discuss how the determination of fundamental parameters is impacted by the model chosen for theoretical uncertainties, illustrating several issues with examples from quark flavor physics. (orig.)
Game theoretic analysis of physical protection system design
International Nuclear Information System (INIS)
Canion, B.; Schneider, E.; Bickel, E.; Hadlock, C.; Morton, D.
2013-01-01
The physical protection system (PPS) of a fictional small modular reactor (SMR) facility have been modeled as a platform for a game theoretic approach to security decision analysis. To demonstrate the game theoretic approach, a rational adversary with complete knowledge of the facility has been modeled attempting a sabotage attack. The adversary adjusts his decisions in response to investments made by the defender to enhance the security measures. This can lead to a conservative physical protection system design. Since defender upgrades were limited by a budget, cost benefit analysis may be conducted upon security upgrades. One approach to cost benefit analysis is the efficient frontier, which depicts the reduction in expected consequence per incremental increase in the security budget

XXIII SERC School in Theoretical High Energy Physics (SERC THEP)
2013-01-01
The recent discovery at the Large Hadron Collider, of what is very likely the Higgs particle, has given a fillip to research in High Energy physics. These experiments hold the promise of a glimpse of physics beyond the Standard Model, which while having been verified to great accuracy, cannot be the final theory. Uncomfortable gaps -both theoretical and experimental- remain in our understanding. Lecture notes from the SERC School in Theoretical High Energy Physics held at IIT Bombay in February 2008 are contained in this volume. Topics that were covered then are of continuing importance, more so in the light of the ongoing LHC experiment. The various chapters in the book include an extensive survey of LHC physics that together with formal aspects and models of supersymmetry, review the state of the art in our understanding of the Standard Model and beyond. The article on B Physics and CP violations add to this, while the chapter on thermal field theory reviews the formalism necessary to understand the early u...

The Purdue High Energy Physics Group conducts research in experimental and theoretical elementary particle physics and experimental high energy astrophysics. Our goals, which we share with high energy physics colleagues around the world, are to understand at the most fundamental level the nature of matter, energy, space and time, and in order to explain the birth, evolution and fate of the Universe. The experiments in which we are currently involved are: CDF, CLEO-c, CMS, LSST, and VERITAS. We have been instrumental in establishing two major in-house facilities: The Purdue Particle Physics Microstructure Detector Facility (P3MD) in 1995 and the CMS Tier-2 center in 2005. The research efforts of the theory group span phenomenological and theoretical aspects of the Standard Model as well as many of its possible extensions. Recent work includes phenomenological consequences of supersymmetric models, string theory and applications of gauge/gravity duality, the cosmological implications of massive gravitons, and the physics of extra dimensions.

Feyerabend's 'The concept of intelligibility in modern physics' (1948).
Kuby, Daniel
2016-06-01
This essay introduces the transcription and translation of Paul Feyerabend's Der Begriff der Verständlichkeit in der modernen Physik [The concept of intelligibility in modern physics] (1948), which is an early essay written by Paul Feyerabend in 1948 on the topic of intelligibility (Verständlichkeit) and visualizability (Anschaulichkeit) of physical theories. The existence of such essay was likely. It is listed in his bibliography as his first publication. Yet the content of the essay was unknown, as no original or copy is extant in Feyerabend's Nachlass and no known published version was available to the community-until now. The essay has both historical and philosophical interest: it is, as far as our current knowledge goes, Feyerabend's earliest extant publication. It documents Feyerabend's philosophical interest as a physicist-to-be, in what he himself called his "positivist" phase; and it gives a rare if fragmentary insight into the early discussions of the 'Third Vienna Circle' and, more generally, the philosophical culture of discussion in Vienna.

Physics of mind: Experimental confirmations of theoretical predictions.
Schoeller, Félix; Perlovsky, Leonid; Arseniev, Dmitry
2018-02-02
What is common among Newtonian mechanics, statistical physics, thermodynamics, quantum physics, the theory of relativity, astrophysics and the theory of superstrings? All these areas of physics have in common a methodology, which is discussed in the first few lines of the review. Is a physics of the mind possible? Is it possible to describe how a mind adapts in real time to changes in the physical world through a theory based on a few basic laws? From perception and elementary cognition to emotions and abstract ideas allowing high-level cognition and executive functioning, at nearly all levels of study, the mind shows variability and uncertainties. Is it possible to turn psychology and neuroscience into so-called "hard" sciences? This review discusses several established first principles for the description of mind and their mathematical formulations. A mathematical model of mind is derived from these principles. This model includes mechanisms of instincts, emotions, behavior, cognition, concepts, language, intuitions, and imagination. We clarify fundamental notions such as the opposition between the conscious and the unconscious, the knowledge instinct and aesthetic emotions, as well as humans' universal abilities for symbols and meaning. In particular, the review discusses in length evolutionary and cognitive functions of aesthetic emotions and musical emotions. Several theoretical predictions are derived from the model, some of which have been experimentally confirmed. These empirical results are summarized and we introduce new theoretical developments. Several unsolved theoretical problems are proposed, as well as new experimental challenges for future research. Copyright © 2017. Published by Elsevier B.V.

A review of novel approaches to solution of multiparticle scattering problems in the area above three-body breakup together with the review of new computational technologies which provide very effective and ultrafast realization of the novel approaches with ordinary PC are given. The novel direction presented here is based on two key points: a new formulation of the quantum scattering theory in a discrete Hilbert space of stationary wave packets and the massive-parallel solution of the resulted matrix equations with usage of ultrafast graphic processors (the so called GPU-computations). For the reader’s convenience, a short review of the modern GPU calculations for the medicine, physics, military applications etc. is presented.
PREFACE: 2nd International Symposium on the Modern Physics of Compact Stars and Relativistic Gravity
Edvard Chubaryan, Professor; Aram Saharian, Professor; Armen Sedrakian, Professor
2014-03-01
The international conference ''The Modern Physics of Compact Stars and Relativistic Gravity'' took place in Yerevan, Armenia, from 18-21 September 2013. This was the second in a series of conferences which aim to bring together people working in astrophysics of compact stars, physics of dense matter, gravitation and cosmology, observations of pulsars and binary neutron stars and related fields. The conference was held on the occasion of 100th birthday of the founder of the Theoretical Physics Chair at the Department of Physics of Yerevan State University and prominent Armenian scientist Academician Gurgen S Sahakyan. The field of compact stars has seen extraordinary development since the discovery of pulsars in 1967. Even before this discovery, pioneering work of a number of theoretical groups had laid the foundation for this development. A pioneer of this effort was Professor G S Sahakyan who, together with Professor Victor Ambartsumyan and a group of young scientists, started in the early sixties their fundamental work on the properties of superdense matter and on the relativistic structure of compact stellar objects. This conference explored the vast diversity of the manifestations of compact stars, including the modern aspects of the equation of state of superdense matter, its magnetic and thermal properties, rotational dynamics, superfluidity and superconductivity, phase transition from hadronic to quark matter, etc. The articles on these subjects collected in this volume are evidence of liveliness of the field and of the continuous feedback between theory and the experiment. A part of this volume is devoted to the cosmology and the theories of gravity — the subfields of astrophysics that are of fundamental importance to our understanding of the universe. The reader will find here articles touching on the most diverse aspects of these fields such as modern problems in Einstein's classical theory of gravity and its alternatives, string theory motivated
We need theoretical physics approaches to study living systems
Blagoev, Krastan B.; Shukla, Kamal; affil="3" >Herbert Levine,
2013-08-01
Living systems, as created initially by the transition from assemblies of large molecules to self-reproducing information-rich cells, have for centuries been studied via the empirical toolkit of biology. This has been a highly successful enterprise, bringing us from the vague non-scientific notions of vitalism to the modern appreciation of the biophysical and biochemical bases of life. Yet, the truly mind-boggling complexity of even the simplest self-sufficient cells, let alone the emergence of multicellular organisms, of brain and consciousness, and to ecological communities and human civilizations, calls out for a complementary approach. In this editorial, we propose that theoretical physics can play an essential role in making sense of living matter. When faced with a highly complex system, a physicist builds simplified models. Quoting Philip W Anderson's Nobel prize address, 'the art of model-building is the exclusion of real but irrelevant parts of the problem and entails hazards for the builder and the reader. The builder may leave out something genuinely relevant and the reader, armed with too sophisticated an experimental probe, may take literally a schematized model. Very often such a simplified model throws more light on the real working of nature....' In his formulation, the job of a theorist is to get at the crux of the system by ignoring details and yet to find a testable consequence of the resulting simple picture. This is rather different than the predilection of the applied mathematician who wants to include all the known details in the hope of a quantitative simulacrum of reality. These efforts may be practically useful, but do not usually lead to increased understanding. To illustrate how this works, we can look at a non-living example of complex behavior that was afforded by spatiotemporal patterning in the Belousov-Zhabotinsky reaction [1]. Physicists who worked on this system did not attempt to determine all the relevant chemical intermediates
The quantum mechanics solver. How to apply quantum theory to modern physics. 2. ed.

Basdevant, J.L.; Dalibard, J.
2006-01-01
The Quantum Mechanics Solver uniquely illustrates the application of quantum mechanical concepts to various fields of modern physics. It aims at encouraging the reader to apply quantum mechanics to research problems in fields such as molecular physics, condensed matter physics or laser physics. Advanced undergraduates and graduate students will find a rich and challenging source of material for further exploration. This book consists of a series of problems concerning present-day experimental or theoretical questions on quantum mechanics. All of these problems are based on actual physical examples, even if sometimes the mathematical structure of the models under consideration is simplified intentionally in order to get hold of the physics more rapidly. The new edition features new themes, such as the progress in measuring neutrino oscillations, quantum boxes, the quantum thermometer etc. Secondly, it includes a brief summary on the basics of quantum mechanics and the formalism we use. Finally, the problems under three main themes: Elementary Particles, Nuclei and Atoms; Quantum Entanglement and Measurement; and Complex Systems. (orig.)

2017-05-01
Full Text Available Based on the recognition of the urgency of the theme of gender and sexuality within the approach of the difference inclusion in School Physical education by academic research, in this article, we focus the notion of masculinity. We present and problematize the Raewyn Connell‟s theory of hegemonic masculinity, as well as the queer perspective, theoretical references identified in the literature review, which is also exposed. Based on the proposal of Jacques Derrida‟s deconstruction and the notion of performative gender, as developed by Judith Butler, we conclude this reflection with the proposition of normalizing masculinity and queer masculinity as search operators, in the theoretical and political will to favor openness to a more radical inclusion in research and lessons of SPE.

Some of you may remember the 1979 television series "Connections" that was written and narrated by James Burke, a British science writer. Burke's technique was to choose a number of seemingly unrelated ideas and show how they led to developments in science and technology. This is an enjoyable business, even if some of the connections seem to be stretched at times, and led to a book by Burke. In a number of talks that I have given over the years, I have made somewhat less fanciful connections that suggest how the technologies of high vacuum and high voltage led to what used to be called "modern physics." Today we might limit the "modern" era to the years from 1890 to 1920 that gave the first workable theories of small-scale physics.
Modern physics and engineering technology for the world year of physics 2005

In the course of progress of the modern society, physics as part of fundamental science, and engineering technology, which is on the applied side of the scientific spectrum, have played different roles. However, there are strong correlation and close interactions between them. By examining the relations between physics and nuclear energy, laser technology, and astronautics, the paper shows that modern physics has taken a leading role in opening up new areas of engineering technology. And conversely, while directly raising productivity, engineering technology has also provided new conditions and environment and more powerful means with which the research of physical science has been explored both more vastly and deeply. The paper further stipulates that, while benefiting each other by mutual progress and interpenetration, physics and engineering technology work hand in hand with philosophy and other social sciences, jointly promoting economic and social development. Faced with lofty historical duties in the process of understanding and transforming the world, physicists and engineers are required to posses some common, good qualities. (author)

A history of the ideas of theoretical physics essays on the nineteenth and twentieth century physics
D’Agostino, Salvo
2000-01-01
This book presents a perspective on the history of theoretical physics over the past two hundreds years. It comprises essays on the history of pre-Maxwellian electrodynamics, of Maxwell's and Hertz's field theories, and of the present century's relativity and quantum physics. A common thread across the essays is the search for and the exploration of themes that influenced significant con ceptual changes in the great movement of ideas and experiments which heralded the emergence of theoretical physics (hereafter: TP). The fun. damental change involved the recognition of the scien tific validity of theoretical physics. In the second half of the nine teenth century, it was not easy for many physicists to understand the nature and scope of theoretical physics and of its adept, the theoreti cal physicist. A physicist like Ludwig Boltzmann, one of the eminent contributors to the new discipline, confessed in 1895 that, "even the formulation of this concept [of a theoretical physicist] is not entirely without...

This volume contains the invited and contributed papers presented at the 14th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 29-31 October, 2013. The meeting was held at the Palazzone, an elegant Renaissance Villa, commissioned by the Cardinal Silvio Passerini (1469-1529), Bishop of Cortona, and presently owned by the Scuola Normale Superiore di Pisa. The aim of this biennial Conference is to bring together Italian theorists working in various fields of nuclear physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to stimulate new ideas and promote collaborations between different research groups. The Conference was attended by 46 participants, coming from 13 Italian Universities and 11 Laboratories and Sezioni of the Istituto Nazionale di Fisica Nucleare - INFN. The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on the following main topics: Few-Nucleon Systems Nuclear Structure Nuclear Matter and Nuclear Dynamics Relativistic Heavy Ion Collisions and Quark-Gluon Plasma Nuclear Astrophysics Nuclear Physics with Electroweak Probes Structure of Hadrons and Hadronic Matter. In the last session of the Conference there were two invited review talks related to experimental activities of great current interest. Giacomo De Angelis from the Laboratori Nazionali di Legnaro spoke about the INFN SPES radioactive ion beam project. Sara Pirrone, INFN Sezione di Catania, gave a talk on the symmetry energy and isospin physics with the CHIMERA detector. Finally, Mauro Taiuti (Università di Genova), National Coordinator of the INFN-CSN3 (Nuclear Physics Experiments), reported on the present status and future challenges of experimental nuclear physics in Italy.

‘Is the modernity of Chinese art comparable? An opening of a theoretical space’

John Clark
2014-06-01
Full Text Available The expansion of the art market and in some ways ‘Western’ art cultural obsession with the way modern Chinese art has entered the world since the early 1980s has overshadowed many issues critical for modern art historiography concerning both China and its place in a modern Asian art. Is Chinese modern art of one kind, and does it have a similar conceptual and empirical topology to other modernities in Asia? Can we examine how these art cultures face the same issues over time? I examine the similarity between Asian cases such as China and Thailand and indicate some of the ways in which an Asian modernity in art can be mapped that is relatively independent of Euramerican types or models.
Informing Physics: Jacob Bekenstein and the Informational Turn in Theoretical Physics
Belfer, Israel
2014-03-01
In his PhD dissertation in the early 1970s, the Mexican-Israeli theoretical physicist Jacob Bekenstein developed the thermodynamics of black holes using a generalized version of the second law of thermodynamics. This work made it possible for physicists to describe and analyze black holes using information-theoretical concepts. It also helped to transform information theory into a fundamental and foundational concept in theoretical physics. The story of Bekenstein's work—which was initially opposed by many scientists, including Stephen Hawking—highlights the transformation within physics towards an information-oriented scientific mode of theorizing. This "informational turn" amounted to a mild-mannered revolution within physics, revolutionary without being rebellious.
Theoretical femtosecond physics atoms and molecules in strong laser fields
Grossmann, Frank
2013-01-01
Theoretical investigations of atoms and molecules interacting with pulsed or continuous wave lasers up to atomic field strengths on the order of 10^16 W/cm² are leading to an understanding of many challenging experimental discoveries. This book deals with the basics of femtosecond physics and goes up to the latest applications of new phenomena. The book presents an introduction to laser physics with mode-locking and pulsed laser operation. The solution of the time-dependent Schrödinger equation is discussed both analytically and numerically. The basis for the non-perturbative treatment of laser-matter interaction in the book is the numerical solution of the time-dependent Schrödinger equation. The light field is treated classically, and different possible gauges are discussed. Physical phenonema, ranging from Rabi-oscillations in two-level systems to the ionization of atoms, the generation of high harmonics, the ionization and dissociation of molecules as well as the control of chemical reactions are pre...

Nuclear Fermi Dynamics: physical content versus theoretical approach
International Nuclear Information System (INIS)
Griffin, J.J.
1977-01-01
Those qualitative properties of nuclei, and of their energetic collisions, which seem of most importance for the flow of nuclear matter are listed and briefly discussed. It is suggested that nuclear matter flow is novel among fluid dynamical problems. The name, Nuclear Fermi Dynamics, is proposed as an appropriate unambiguous label. The Principle of Commensurability, which suggests the measurement of the theoretical content of an approach against its expected predictive range is set forth and discussed. Several of the current approaches to the nuclear matter flow problem are listed and subjected to such a test. It is found that the Time-Dependent Hartree-Fock (TDHF) description, alone of all the major theoretical approaches currently in vogue, incorporates each of the major qualitative features within its very concise single mathematical assumption. Some limitations of the conventional TDHF method are noted, and one particular defect is discussed in detail: the Spurious Cross Channel Correlations which arise whenever several asymptotic reaction channels must be simultaneously described by a single determinant. A reformulated Time-Dependent-S-Matrix Hartree-Fock Theory is proposed, which obviates this difficulty. It is noted that the structure of TD-S-HF can be applied to a more general class of non-linear wave mechanical problems than simple TDHF. Physical requirements minimal to assure that TD-S-HF represents a sensible reaction theory are utilized to prescribe the definition of acceptable asymptotic channels. That definition, in turn, defines the physical range of the TD-S-HF theory as the description of collisions of certain mathematically well-defined objects of mixed quantal and classical character, the ''TDHF droplets.''
Information Theoretic Characterization of Physical Theories with Projective State Space
Zaopo, Marco
2015-08-01
Probabilistic theories are a natural framework to investigate the foundations of quantum theory and possible alternative or deeper theories. In a generic probabilistic theory, states of a physical system are represented as vectors of outcomes probabilities and state spaces are convex cones. In this picture the physics of a given theory is related to the geometric shape of the cone of states. In quantum theory, for instance, the shape of the cone of states corresponds to a projective space over complex numbers. In this paper we investigate geometric constraints on the state space of a generic theory imposed by the following information theoretic requirements: every non completely mixed state of a system is perfectly distinguishable from some other state in a single shot measurement; information capacity of physical systems is conserved under making mixtures of states. These assumptions guarantee that a generic physical system satisfies a natural principle asserting that the more a state of the system is mixed the less information can be stored in the system using that state as logical value. We show that all theories satisfying the above assumptions are such that the shape of their cones of states is that of a projective space over a generic field of numbers. Remarkably, these theories constitute generalizations of quantum theory where superposition principle holds with coefficients pertaining to a generic field of numbers in place of complex numbers. If the field of numbers is trivial and contains only one element we obtain classical theory. This result tells that superposition principle is quite common among probabilistic theories while its absence gives evidence of either classical theory or an implausible theory.

This paper reviews the current status of our understanding of tracer-diffusion phenomena in colloidal suspensions. This is the most direct observation of the Brownian motion executed by labelled Brownian particles interacting with the rest of colloidal particles in a suspension. The fundamental description of this phenomenon constitutes today one of the most relevant problems in the process of understanding the dynamic properties of this important class of complex fluids, from the experimental and theoretical perspective of physical research. This paper describes the recent developments in the extension of the classical theory of Brownian motion and its application to the description of the effects of direct and hydrodynamic interactions among colloidal particles. As a result, a coherent pictured has emerged in which the agreement between theory and experiment from nature fields of physics. The moral of the paper is that the use of well established concepts as statistical physics, assisted by modern experimental techniques, are contributing to transform complex fluids into a more amialbe class of materials from the point of view of the physicist.

[Investigations in dynamics of gauge theories in theoretical particle physics
International Nuclear Information System (INIS)
1993-01-01
The major theme of the theoretical physics research conducted under DOE support over the past several years has been within the rubric of the standard model, and concerned the interplay between symmetries and dynamics. The research was thus carried out mostly in the context of gauge field theories, and usually in the presence of chiral fermions. Dynamical symmetry breaking was examined both from the point of view of perturbation theory, as well as from non-perturbative techniques associated with certain characteristic features of specific theories. Among the topics of research were: the implications of abelian and non-abelian anomalies on the spectrum and possible dynamical symmetry breaking in any theory, topological and conformal properties of quantum fields in two and higher dimensions, the breaking of global chiral symmetries by vector-like gauge theories such as QCD, the phenomenological implications of a strongly interacting Higgs sector in the standard model, and the application of soliton ideas to the physics to be explored at the SSC
Theoretical femtosecond physics atoms and molecules in strong laser fields
Grossmann, Frank
2018-01-01
This textbook extends from the basics of femtosecond physics all the way to some of the latest developments in the field. In this updated edition, the chapter on laser-driven atoms is augmented by the discussion of two-electron atoms interacting with strong and short laser pulses, as well as by a review of ATI rings and low energy structures in photo-electron spectra. In the chapter on laser-driven molecules a discussion of 2D infrared spectroscopy is incorporated. Theoretical investigations of atoms and molecules interacting with pulsed lasers up to atomic field strengths on the order of 10^16 W/cm² are leading to an understanding of many challenging experimental discoveries. The presentation starts with a brief introduction to pulsed laser physics. The basis for the non-perturbative treatment of laser-matter interaction in the book is the time-dependent Schrödinger equation. Its analytical as well as numerical solution are laid out in some detail. The light field is treated classically and different possi...
PREFACE: 12th Conference on ''Theoretical Nuclear Physics in Italy''
Bombaci, I.; Covello, A.; Marcucci, L. E.; Rosati, S.
2009-07-01
These Proceedings contain the invited and contributed papers presented at the 12th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 8-10 October 2008. As usual, the meeting was held at il Palazzone, a 16th century castle owned by the Scuola Normale Superiore di Pisa. The aim of this biennal conference is to bring together Italian theorists working in various fields of Nuclear Physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to promote collaborations between different groups. There were about 50 participants at the conference, coming from 14 Italian Universities (Cagliari, Catania, Ferrara, Firenze, Genova, Lecce, Milano, Napoli, Padova, Pavia, Pisa, Roma, Trento, Trieste). The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on six main topics: Few-Nucleon Systems, Nuclear Matter and Nuclear Dynamics, Nuclear Astrophysics, Structure of Hadrons and Hadronic Matter, Nuclear Structure, Nuclear Physics with Electroweak Probes. Winfried Leidemann, Maria Colonna, Marcello Lissia, Elena Santopinto, Silvia Lenzi and Omar Benhar took the burden of giving general talks on these topics and reviewing the research activities of the various Italian groups. In addition, 19 contributed papers were presented, most of them by young participants. In the last session of the Conference there were two invited talks related to experimental activities of great current interest. Gianfranco Prete from the Laboratori Nazionali di Legnaro spoke about the Italian radioactive ion beam facility SPES and the status of the European project EURISOL, while Nicola Colonna from the INFN, Bari, gave an overview of the perspectives of development of fourth-generation nuclear reactors. We would like to thank the authors of the general reports for their hard work in reviewing the main achievements in

2017-06-01
Full Text Available Finding a favorable trade-off between saving the architectural heritage, and assuring the development of modern architecture is a delicate and precise task, due to the lack of knowledge in the original criteria for the re-thinking of traditional architecture. As a tentative answer to this challenge, this paper attempts to shed light on Mashrabiya (traditional Arab oriel window as a powerful environmental element in modern architecture, with regard to the important functions that it provides, such as light control, airflow regulation, humidity control, temperature regulation and visual privacy. Due to these functions, Mashrabiya achieved widespread popularity around the old world and it has been revived again in many contemporary projects by different modern versions. The objective of this study also is presenting a general evaluation for the modern Mashrabiya to observe the misconceptions of using the Mashrabiya and to call for stop ignoring of the proper standards of Mashrabiya design and to preserve the original name of this element "Mashrabiya".

Quantum Humor: The Playful Side of Physics at Bohr's Institute for Theoretical Physics
Halpern, Paul
2012-09-01
From the 1930s to the 1950s, a period of pivotal developments in quantum, nuclear, and particle physics, physicists at Niels Bohr's Institute for Theoretical Physics in Copenhagen took time off from their research to write humorous articles, letters, and other works. Best known is the Blegdamsvej Faust, performed in April 1932 at the close of one of the Institute's annual conferences. I also focus on the Journal of Jocular Physics, a humorous tribute to Bohr published on the occasions of his 50th, 60th, and 70th birthdays in 1935, 1945, and 1955. Contributors included Léon Rosenfeld, Victor Weisskopf, George Gamow, Oskar Klein, and Hendrik Casimir. I examine their contributions along with letters and other writings to show that they offer a window into some issues in physics at the time, such as the interpretation of complementarity and the nature of the neutrino, as well as the politics of the period.

This textbook mediates in three volumes the matter of the first four semester of the bachelor respectively master course. The otherwise generally usual separate presentation of experimental and theoretical physics is canceled in favor of an integrated treatment. The advances are obvious: The studying is enabled to learn to understand knowledge gotten by means of experiments also immediately in a quantitative formulation. The can equally be used as textbook to an integrated course and to separated courses. Because the relevant theoretical concepts are developed without gap a special book of theoretical physics is unnecessary. Numerous exercise problems deepen the understanding and help directly in the preparation for examinations. The illustrations are mostly presented in two colours. Volume III treats atomic and molecular physics. After a semiclassical presentation the quantum-mechanical foundations are developed and in the following chapters applied to atomic systems and processes. An introduction in the foundations and application of the laser. The closure is formed by a chapter about entangled systems.

The art of memory started with Aristotle's questions on memory. During its long evolution, it had important contributions from alchemists, was transformed by Ramon Llull and apparently ended with Giordano Bruno, who was considered the best known representative of this art. This tradition did not disappear, but lives in the formulations of our modern scientific theories. From its initial form as a method of keeping information via associations, it became a principle of classification and structuring of knowledge. This principle, which we here name differentiation with stratification, is a structural design behind classical mechanics. Integrating two different traditions of science in one structure, this physical theory became the modern paradigm of science. In this paper, we show that this principle can also be formulated as a set of questions. This is done via an analysis of theories, based on the epistemology of observational realism. A combination of Rudolph Carnap's concept of theory as a system of observational and theoretical languages, with a criterion for separating observational languages, based on analytical psychology, shapes this epistemology. The `nuclear' role of the observational laws and the differentiations from these nucleus, reproducing the general cases of phenomena, reveals the memory art's heritage in the theories. Here in this paper we argue that this design is also present in special relativity and in quantum mechanics.

Lectures on torah and modern physics (the lectures in kabbalah series)
Ginsburgh, Harav Yitzchak
2013-01-01
Modern physics has forever changed the way we view and understand physical reality. With a wide spectrum of theories, from general relativity to quantum mechanics, our conceptions of the very big and the very small are no longer intuitively obvious. Many philosophers, even scientists have expressed the opinion that the counterintuitive conclusions posited in modern physics are best understood using spiritual terminology. In the 11 lectures in this volume, Harav Ginsburgh, one of our generation's foremost scholars, innovators, and teachers of Kabbalah, reveals how modern physics reflects foundational concepts in the Torah's inner dimension. A wide range of topics from relativity (special and general), quantum mechanics, and string theory are addressed. Elegantly and gracefully, Harav Ginsburgh's exposition of the topics switches back and forth between the scientific and Torah perspectives. With his deep insight, Harav Ginsburgh gives even well-known physical concepts a refreshing and new treatment. Apart from ...

Bookshelf (Conceptual Foundations of Modern Particle Physics, by Robert E. Marshak)
International Nuclear Information System (INIS)
Fritzsch, Harald
1994-01-01
Particle physics really began as an independent scientific discipline after the Second World War. Robert Marshak was one of its pioneers on the theoretical front, starting out his career with important contributions on meson theory (together with Hans Bethe). The life of Marshak, who died in December 1992, was intimately interwoven with the post-war development of particle physics. His work on weak interaction theory was an important step towards the formulation of the V-A theory, the main pillar on which the modern electroweak theory rests erected. He is also remembered as the founder of the biennial 'Rochester' conference series (March 1993, page 24). Just before his death Robert Marshak finished writing his book on the concepts of particle physics. The book starts out with an historical account of the development of the field. He divides it into the startup period (1945-60) - the period of meson physics, the physics of strange particles, parity violation etc; the heroic period (1960-1975) when the Standard Model of the electroweak and strong interactions was developed; and finally the period of consolidation and speculation (since 1975). Marshak's recollection of the development of particle physics represents a personal view, worth reading by young researchers, although it does not attempt to provide a complete picture. After the historical chapter Marshak introduces the reader to the basics of quantum field theory (space-time symmetries, global internal symmetries and their breaking, gauge symmetries). Later he turns to a description of QCD and the gauge theory of the electroweak interactions. A whole chapter is devoted to the problems related to anomalies. In the last part of the book Marshak discusses various hypotheses of unifying the strong and electroweak interactions, especially the various facets of the SO(10) theory, followed by a long discussion of the fermion generation problem and of preon models. The book concludes with an extensive
The concept of intelligibility in modern physics (1948).
Feyerabend, Paul K
2016-06-01
This is an English translation of Paul Feyerabend's earliest extant essay "Der Begriff der Verständlichkeit in der modernen Physik" (1948). In it, Feyerabend defends positivism as a progressive framework for scientific research in certain stages of scientific development. He argues that in physics visualizability (Anschaulichkeit) and intelligibility (Verständlichkeit) are time-conditioned concepts: what is deemed visualizable in the development of physical theories is relative to a specific historical context and changes over time. He concludes that from time to time the abandonment of visualizability is crucial for progress in physics, as it is conducive to major theory change, illustrating the point on the basis of advances in atomic theory.

By examining the works of the Argentine writer, Jorge Luis Borges, and the parallels it has with modern physics, literature and science converge in their quest for truth regarding the structure and meaning of the universe. The classical perception of physics as a "hard" science--that of quantitative, rational thought which was established during the Newtonian era--has been replaced by the "new physics," which integrates the so-called "soft" elements into its paradigm. It presents us with a universe based not exclusively on a series of particle-like interactions, or a "billiard-ball" hypothesis where discrete objects have a measurable position and velocity in absolute space and time, but rather on a combination of these mechanistic properties and those that make up the non-physical side of nature such as intuition, consciousness, and emotion. According to physicists like James Jeans science has been "humanized" to the extent that the universe as a "great machine" has been converted into a "great thought.". In nearly all his collections of essays and short stories, Borges complements the new physics by producing a literature that can be described as "scientized." The abstract, metaphysical implications and concerns of the new world-view, such as space, time, language, consciousness, free will, determinism, etc., appear repeatedly throughout Borges' texts, and are treated in terms that are remarkably similar to those expressed in the scientific texts whose authors include Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schrodinger. As a final comparison, Borges and post-modern physicists address the question of the individual's ability to ever comprehend the universe. They share an attitude of incredulity toward all models and theories of reality simply because they are based on partial information, and therefore seen only as conjectures.

Modern elementary particle physics explaining and extending the standard model
Kane, Gordon
2017-01-01
This book is written for students and scientists wanting to learn about the Standard Model of particle physics. Only an introductory course knowledge about quantum theory is needed. The text provides a pedagogical description of the theory, and incorporates the recent Higgs boson and top quark discoveries. With its clear and engaging style, this new edition retains its essential simplicity. Long and detailed calculations are replaced by simple approximate ones. It includes introductions to accelerators, colliders, and detectors, and several main experimental tests of the Standard Model are explained. Descriptions of some well-motivated extensions of the Standard Model prepare the reader for new developments. It emphasizes the concepts of gauge theories and Higgs physics, electroweak unification and symmetry breaking, and how force strengths vary with energy, providing a solid foundation for those working in the field, and for those who simply want to learn about the Standard Model.
Cognition versus Constitution of Objects: From Kant to Modern Physics
Mittelstaedt, Peter
2009-07-01
Classical mechanics in phase space as well as quantum mechanics in Hilbert space lead to states and observables but not to objects that may be considered as carriers of observable quantities. However, in both cases objects can be constituted as new entities by means of invariance properties of the theories in question. We show, that this way of reasoning has a long history in physics and philosophy and that it can be traced back to the transcendental arguments in Kant’s critique of pure reason.
Courses in Modern Physics for Non-science Majors, Future Science Teachers, and Biology Students
Zollman, Dean
2001-03-01
For the past 15 years Kansas State University has offered a course in modern physics for students who are not majoring in physics. This course carries a prerequisite of one physics course so that the students have a basic introduction in classical topics. The majors of students range from liberal arts to engineering. Future secondary science teachers whose first area of teaching is not physics can use the course as part of their study of science. The course has evolved from a lecture format to one which is highly interactive and uses a combination of hands-on activities, tutorials and visualizations, particularly the Visual Quantum Mechanics materials. Another course encourages biology students to continue their physics learning beyond the introductory course. Modern Miracle Medical Machines introduces the basic physics which underlie diagnosis techniques such as MRI and PET and laser surgical techniques.

John Archibald Wheeler: A study of mentoring in modern physics
Christensen, Terry M.
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body of literature dealing with Research Schools and the emerging scholarship surrounding the development, dispersion, and evolution of pedagogy in the training of twentieth century physicists. The second, and perhaps more significant and novel objective, is to develop a means to quantitatively assess the mentoring workmanship of scientific craftsmen who preside over the final stages of preparation when apprentices are transformed into professional scientists. The project builds upon a 2006 Master's Thesis that examined John Archibald Wheeler's work as a mentor of theoretical physicists at Princeton University in the years 1938--1976. It includes Wheeler's work as a mentor at the University of Texas and is qualitatively and quantitatively enhanced by virtue of the author having access to five separate collections with archival holdings of John Wheeler's papers and correspondence, as well as having access to thirty one tape recorded interviews that feature John Wheeler as either the interviewee or a prominent subject of discussion. The project also benefited from the opportunity to meet with and gather background information from a number of John Wheeler's former colleagues and students. Included in the dissertation is a content analysis of the acknowledgements in 949 Ph.D. dissertations, 122 Master's Theses, and 670 Senior Theses that were submitted during Wheeler's career as an active mentor. By establishing a census of the students of the most active mentors at Princeton and Texas, it is possible to tabulate the publication record of these apprentice groups and obtain objective measures of mentoring efficacy. The dissertation concludes by discussing the wider

Signposts to God how modern physics and astronomy point the way to belief
Bussey, Peter
2016-01-01
In Signposts to God particle physicist Peter Bussey introduces readers to the mysteries of modern physics and astronomy. Written in clear, accessible prose, Bussey provides a primer on topics such as the laws of nature, quantum physics, fine-tuning, and current cosmological models. He shows that despite the remarkable achievements of science, the latest research in these fields does not lead to simple physicalism in which physical processes are able to explain everything that exists. Bussey argues that, far from ruling out a divine Creator, modern physics and astronomy present us with compelling signposts to God. The more we know about the cosmos and our presence in it, the more plausible belief in God becomes. We can be intellectually satisfied in both science and the Christian faith. Written by someone who has worked for years in scientific research, Signposts to God is a timely and winsome response to a cultural stalemate.

Full Text Available The purpose of the article is to characterize the development and specific features of inflation in Russia on the basis of its theoretical justification and practical analysis. The article discusses the monetarist and Keynesian approaches to the characterization of inflation. The paper shows that the equation of exchange from the quantity theory of money, which is the basis of the monetarist theory of inflation, does not allow to make an unambiguous conclusion about the direct relationship between money supply and price level in the economy. The authors give the theoretical substantiation of cost-push inflation from the position of microeconomic theory, which is denied by the representatives of the monetarist school. We characterize the specific features of inflation in the period of market transformations in Russia. The article shows the considerable role of the cost factors of cost-push inflation: the monopolization of the economy, rise in the prices of energy and raw materials. There is an absence of the direct relationship between inflation and money supply growth in large part of the period of the 2000. The authors determine the dependence between the exchange rate and inflation in the Russian economy, which is most evident during periods of significant devaluation of the national currency, as a rule, associated with a significant increase in world oil prices. The paper notes that the significant decline in aggregate demand that occurred in Russia in recent years have reduced the level of inflation in 2016. Despite this, the reduction of inflation and its transformation to slow cost-push inflation was combined with negative consequences for the economy: the decrease of investments and production development, reduction of the living standards of the population. The authors conducted the analysis of inflation on the level of the subjects of the Russian Federation, which has confirmed the significant role of causes of cost-push inflation in

This book is an entertaining and formula-free presentation of modern physics from the 19th century to present. The life of Albert Einstein and his scientific works are drawn as red fathom through the text. The author explains central terms and results of modern physics in populary-scientific form from the historical perspective. To the reader in humorous form an imagination is mediated how modern physics has been developed. We learn from the exciting effects of the ether, we hear from faraday and magnetic needles, from Maxwell's prediction of the electromagnetic waves, from heinrich Hertz and from the photoelectric effect. Was the Michelson-Morley experiment a measurement success or an unsuccess? Why has Einstein abandoned the ether? How has Einstein in the miraculous year 1905 revolutionated physics and why he has begged Newton for excusement? Exist atoms? What is motion? What is light and what is to be understood under ''now'' and ''here''? Light deviation or non-deviation? How act the tidal forces? And above all: How has Einstein answered these questions. We meet Poincare, Lorentz and Hilbert, Boltzmann and Bohr, Minkowski, Planck, de Broglie, Hubble and Weyl, Gamow, Hahn and Meitner, Kapiza and Landau, Fermi and many other famous scientists. What had Eddington against Chandrasekhar and what had Einstein against black holes? Why should space tourists and dream tourists make holiday not on the Loch Ness but on the safe side of a black hole? Why inveighed Pauli against Einstein? Is the concern with the atomic-bomb formula right? Smeared matter, big bang and cosmic background radiation, gravitational waves and double pulsars, the cosmological constant and the expansion of the universe are further themes, which keep the reader in breath and let no mental vacuum arise.

Full Text Available According to their genetic potential, biological characteristics and environmental factors, the study of physical growth allows us to understand the variability of this process in humans. Extrinsic and intrinsic factors could affect the normal process of physical growth, which are studied through different types of research, becoming an interesting subject for professionals in the health sciences. The aim of this study is to analyze the factors affecting physical growth and describe the types of research (transverse, longitudinal and ex post facto used in the study of physical growth. Intrinsic factors, environmental factors and the interaction between them should be studied in diverse population prioritizing the potential factors affecting physical growth of children and adolescents. This will diagnose, classify and monitor physical growth versus time (transverse and longitudinal and retrospectively (ex post facto. Consequently, the possibility for researchers and/or private and government institutions arises to promote validated anthropometric studies, helping to implement effective health policies for various purposes such as excess weight control in childhood and other disease entities related nutrition.
Constructing the principles: Method and metaphysics in the progress of theoretical physics
Glass, Lawrence C.
This thesis presents a new framework for the philosophy of physics focused on methodological differences found in the practice of modern theoretical physics. The starting point for this investigation is the longstanding debate over scientific realism. Some philosophers have argued that it is the aim of science to produce an accurate description of the world including explanations for observable phenomena. These scientific realists hold that our best confirmed theories are approximately true and that the entities they propose actually populate the world, whether or not they have been observed. Others have argued that science achieves only frameworks for the prediction and manipulation of observable phenomena. These anti-realists argue that truth is a misleading concept when applied to empirical knowledge. Instead, focus should be on the empirical adequacy of scientific theories. This thesis argues that the fundamental distinction at issue, a division between true scientific theories and ones which are empirically adequate, is best explored in terms of methodological differences. In analogy with the realism debate, there are at least two methodological strategies. Rather than focusing on scientific theories as wholes, this thesis takes as units of analysis physical principles which are systematic empirical generalizations. The first possible strategy, the conservative, takes the assumption that the empirical adequacy of a theory in one domain serves as good evidence for such adequacy in other domains. This then motivates the application of the principle to new domains. The second strategy, the innovative, assumes that empirical adequacy in one domain does not justify the expectation of adequacy in other domains. New principles are offered as explanations in the new domain. The final part of the thesis is the application of this framework to two examples. On the first, Lorentz's use of the aether is reconstructed in terms of the conservative strategy with respect to
Large scale computing in theoretical physics: Example QCD
International Nuclear Information System (INIS)
Schilling, K.
1986-01-01
The limitations of the classical mathematical analysis of Newton and Leibniz appear to be more and more overcome by the power of modern computers. Large scale computing techniques - which resemble closely the methods used in simulations within statistical mechanics - allow to treat nonlinear systems with many degrees of freedom such as field theories in nonperturbative situations, where analytical methods do fail. The computation of the hadron spectrum within the framework of lattice QCD sets a demanding goal for the application of supercomputers in basic science. It requires both big computer capacities and clever algorithms to fight all the numerical evils that one encounters in the Euclidean world. The talk will attempt to describe both the computer aspects and the present state of the art of spectrum calculations within lattice QCD. (orig.)

The main focus of the second, enlarged edition of the book Mathematica for Theoretical Physics is on computational examples using the computer program Mathematica in various areas in physics. It is a notebook rather than a textbook. Indeed, the book is just a printout of the Mathematica notebooks included on the CD. The second edition is divided into two volumes, the first covering classical mechanics and nonlinear dynamics, the second dealing with examples in electrodynamics, quantum mechanics, general relativity and fractal geometry. The second volume is not suited for newcomers because basic and simple physical ideas which lead to complex formulas are not explained in detail. Instead, the computer technology makes it possible to write down and manipulate formulas of practically any length. For researchers with experience in computing, the book contains a lot of interesting and non-trivial examples. Most of the examples discussed are standard textbook problems, but the power of Mathematica opens the path to more sophisticated solutions. For example, the exact solution for the perihelion shift of Mercury within general relativity is worked out in detail using elliptic functions. The virial equation of state for molecules' interaction with Lennard-Jones-like potentials is discussed, including both classical and quantum corrections to the second virial coefficient. Interestingly, closed solutions become available using sophisticated computing methods within Mathematica. In my opinion, the textbook should not show formulas in detail which cover three or more pages-these technical data should just be contained on the CD. Instead, the textbook should focus on more detailed explanation of the physical concepts behind the technicalities. The discussion of the virial equation would benefit much from replacing 15 pages of Mathematica output with 15 pages of further explanation and motivation. In this combination, the power of computing merged with physical intuition would

The program will consist of a pedagogical series of lectures and seminars. Lectures will be given over a four-week period, three or four lectures per day, Monday through Friday. The audience will be composed primarily of advanced theoretical graduate students. Experimentalists with a strong background in theory are also encouraged to apply. Some post-doctoral fellows will be admitted, but preference will be given to applicants who will not have received their Ph.D. before 2017. The minimum background needed to get full benefit of TASI is a knowledge of quantum field theory (including RGEs) and familiarity with the Standard Model. Some familiarity with SUSY would be helpful. We hope to provide some subsidy, but students will need partial support from other sources. Rooms, meals, and access to all facilities will be provided at reasonable rates in beautifully located dormitories at the University of Colorado.
Physics of human cooperation: experimental evidence and theoretical models
Sánchez, Angel
2018-02-01
In recent years, many physicists have used evolutionary game theory combined with a complex systems perspective in an attempt to understand social phenomena and challenges. Prominent among such phenomena is the issue of the emergence and sustainability of cooperation in a networked world of selfish or self-focused individuals. The vast majority of research done by physicists on these questions is theoretical, and is almost always posed in terms of agent-based models. Unfortunately, more often than not such models ignore a number of facts that are well established experimentally, and are thus rendered irrelevant to actual social applications. I here summarize some of the facts that any realistic model should incorporate and take into account, discuss important aspects underlying the relation between theory and experiments, and discuss future directions for research based on the available experimental knowledge.
Science and society the history of modern physical science in the twentieth century
Gordin, Michael; Kaiser, David
2001-01-01
Modern science has changed every aspect of life in ways that cannot be compared to developments of previous eras. This four volume set presents key developments within modern physical science and the effects of these discoveries on modern global life. The first two volumes explore the history of the concept of relativity, the cultural roots of science, the concept of time and gravity before, during, and after Einstein's theory, and the cultural reception of relativity. Volume three explores the impact of modern science upon global politics and the creation of a new kind of war, and Volume four details the old and new efforts surrounding the elucidation of the quantum world, as well as the cultural impact of particle physics. The collection also presents the historical and cultural context that made these scientific innovations possible. The transformation of everyday concepts of time and space for the individual and for society, the conduct of warfare, and the modern sense of mastering nature are all issues d...

Ettore Majorana unpublished research notes on theoretical physics
Recami, E; Van der Merwe, A; Battiston, R
2009-01-01
The editors of this volume bring to life a major part of Ettore Majorana’s work that up to now was not accessible to the general audience. These are the contents of the Quaderni (notebooks) of Ettore Majorana, edited and translated in English. Ettore Majorana had an astounding talent for Physics that made an impression on all the colleagues who had the opportunity to know him. Enrico Fermi, who took him in his group when he was a student, ranked him with Galilei and Newton. Ettore Majorana’s career was cut short in 1938, as he mysteriously disappeared at the age of 32, leaving many unpublished works. This book reveals an interesting perspective over the points of view, the interests, the approach to physical problems of this great physicist and it shows that he had advanced his comprehension of physics to levels that were only reached by other physicists ten years after, or even later. The editors have inserted minimal text, in order to leave the original calculations by Majorana intact, and at the same t...

Data analyzed show that the main difficulties presented by the future Physics High School teachers are related to the approach to know physics phenomena as dependent of vision. By other hand, as alternatives, future teachers showed creativity in order to surpass passive aptitudes related to this educational problem and working out methodological strategies deprived of the relation knowing/seeing.

The book also discusses topics on the Quark–Gluon plasma, thermal field theory, perturbative quantum chromodynamics, anomalies and cosmology. Students of particle physics need to be well-equipped with basic understanding of many concepts underlying the standard models of particle physics and cosmology. This is particularly true today when experimental results from colliders, such as large hadron collider (LHC) and relativistic heavy ion collider (RHIC), as well as inferences from cosmological observations, are expected to further expand our understanding of particle physics at high energies. This volume is the second in the Surveys in Theoretical High Energy Physics Series (SThEP). Topics covered in this book are based on lectures delivered at the SERC Schools in Theoretical High Energy Physics at the Physical Research Laboratory, Ahmedabad, and the University of Hyderabad.
The second physicist on the history of theoretical physics in germany
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 short course in quantum information theory. An approach from theoretical physics

Diosi, L.
2007-01-01
This short and concise primer takes the vantage point of theoretical physics and the unity of physics. It sets out to strip the burgeoning field of quantum information science to its basics by linking it to universal concepts in physics. An extensive lecture rather than a comprehensive textbook, this volume is based on courses delivered over several years to advanced undergraduate and beginning graduate students, but essentially it addresses anyone with a working knowledge of basic quantum physics. Readers will find these lectures a most adequate entry point for theoretical studies in this field. (orig.)

The research includes applications of many-body scattering theory to nuclear systems and studies of few-body systems described by effective hadronic field theories. Progress was made in bringing all first-order effects into the nonrelativistic elastic nucleon-nucleus scattering in a consistent fashion. This work is directed towards completely and reliably calculating the first-order term in a Watson expansion including a modification through the nulear medium. The research effort in few-body physics was concentrated on nucleon-nucleon (NN) scattering below pion production threshold, where recent measurements indicated that the backward-angle neutron-proton (np) differential cross section may show sensitivity to the size of the pion-nucleon coupling constant

LENR/"Cold Fusion" and Modern Physics: A Crisis Within a Crisis
Mallove, Eugene F. E.
2004-03-01
The primary theorists in the field of Cold Fusion/LENR have generally assumed that the excess heat phenomena is commensurate with nuclear ash (such as helium), whether already identified or presumed to be present but not yet found, and moreover that it can be explained by hydrided metal lattice structures acting coherently. Though this was an excellent initial hypothesis, the commensurate nuclear ash hypothesis has not been proved, and appears to be approximately correct in only a few experiments. At the same time, compelling evidence has also emerged for other microphysical sources of energy that were unexpected by accepted physics. The exemplars have been the work Dr. Randell Mills and his colleagues at BlackLight Power Corporation and Dr. Paulo and Alexandra Correa in Canada.This has led to a crisis within a crisis: Neither "cold fusion" nor "Modern Physics" will be able to explain the full range of experimental data now available---not even the data within "mainstream" cold fusion/LENR per se--- by insisting that the fundamental paradigms of Modern Physics are without significant flaw. The present crisis is of magnitude comparable to the Copernican Revolution. Neither Modern Physics nor Cold Fusion/LENR will survive in their present forms when this long delayed revolution has run its course.

Primary emphasis is placed on understanding the nature of nucleon-nucleon and meson-nucleon interactions and on determining the consequences of such microscopic interactions in nuclear systems. We have constructed models of baryons which smoothly interpolate between currently popular bag and Skyrme models of hadrons and provide a vehicle for introducing the notions of quantum chromodynamics to low energy nuclear physics without violating the constraints of chiral invariance. Such models have been used to study the nucleon-nucleon interaction, the spectrum of baryons, and the important question of the radius of the quark bag. We have used many-body techniques to consider a variety of problems in finite nuclei and infinite many-body systems. New light has been shed on the nuclear coexistence of spherical and deformed states in the A = 18 region as well as the role of genuine three-body forces in this region. Phenomenological studies of infinite systems have led to a number of predictions particularly regarding the spin-polarized quantum liquids of current experimental interest. Microscopic many-body theories, based on the parquet diagrams, have been improved to a fully quantitative level for the ground state properties of infinite many-body systems. Finite temperature theories of nuclear matter, important in the study of heavy ion reactions, have been constructed. An expanded program in heavy ion theory has led to major advances in the multi-dimensional barrier penetration problem. Activities in nuclear astrophysics have provided a far more reliable description of the role of electron capture processes in stellar collapse. As a consequence, we have been able to perform legitimate calculations of the unshocked mass in Type II supernovae

The fifty participants in the Physics Teachers programme in the Microcosm garden. High school students are often convinced that physics is a boring and useless subject, and physics teachers have a hard time presenting interesting lessons. To help them, CERN has inaugurated the Physics Teachers Programme, whose goal is to present CERN and its activities, so that teachers can get an idea of what kind of physics research is going on at the frontier of science. 'Our philosophy is to show them today what they will read in textbooks of the future', says Antonella Del Rosso, responsible for this course, 'so that they can inspire their pupils'. This programme can be considered the younger brother of the High School Teachers Programme, since it has a similar aim, but instead of being three-weeks long, it las...

This book presents experiments which will teach physics relevant to astronomy. The astronomer, as instructor, frequently faces this need when his college or university has no astronomy department and any astronomy course is taught in the physics department. The physicist, as instructor, will find this intellectually appealing when faced with teaching an introductory astronomy course. From these experiments, the student will acquire important analytical tools, learn physics appropriate to astronomy, and experience instrument calibration and the direct gathering and analysis of data. Experiments that can be performed in one laboratory session as well as semester-long observation projects are included. This textbook is aimed at undergraduate astronomy students.

Objective To study dancers’ perceptions of the physical, cognitive, affective, and social benefits of partnered dancing. Method 225 dancers (71% female) were recruited through a community ballroom dance center and completed an online survey designed to measure their perceptions of the physical, cognitive, affective, and social benefits of modern, partnered dance styles (swing, Lindy Hop, and ballroom dancing). Subgroups were formed for analyses. For one set of analyses, groups based on length of dance participation were formed: experienced (dancing for more than 2 years) or novice (dancing for less than a year) dancers. For another set of analyses, groups based on frequency of dance practice were formed: committed (dancing at least one or more times per week) or occasional (dancing two or fewer times per month). Results The majority of participants reported perceived benefits in physical fitness, cognition, affect, and social functioning. Experienced dancers reported significantly greater self-perceived physical, social, and cognitive benefits than novice dancers. Committed dancers were more likely than occasional dancers to report improvements in physical fitness, U = 6,942, z = 2.38, r = .16, p dance participation significantly predicted perceived physical benefits [X2 (1,6) = 35.463, p dance styles is associated with perceived improvements in physical fitness, cognitive functioning, social functioning, mood, and self-confidence, and that perceived benefits may increase as individuals dance more frequently and over longer periods of time.

In the basic organizing documents of school physical education, there were and still are stipulated the exact requests regarding the necessary theoretical knowledge ofstudents on various education levels. According to these documents, the theoretical knowledge was general knowledge. To the general knowledge, there are added those pertaining to the basic information of the given subject, information about the means and methods of physical education, information from the domain of prophylactic physical education, etc. Special knowledge is that representing the students’ knowledge form various sports tests provided by the school curriculum, such as the sporting games (volleyball, basketball,football, handball, athletics (running, jumping, throwing and gymnastics (apparatus and floor exercises. It is here that the means and methods applied in acquiring the compartments listed above are attributed. In the special knowledge category there is also the knowledge related to the means, the forms and the methods to develop the basic motor qualities (force, speed, flexibility, resistance, skills, as well as the procedures for evaluating them.Nevertheless, regardless of the fact that in the physical education organizing normative documents, highschool included, it is provided that theoretical knowledge should be acquired, still there is no actual presentation of the specific requirements and the assessment criteria for the level of acquisition. No document specifies the ways to evaluate the volume and quality of acquiring the theoretical knowledge, which is why we are going to present here a detailed analysis of the level of acquisition of theoretical knowledge for the “Physical Education” subject by highschool students after applying the teaching –learning -evaluation technique on the

Mental models are coherently organized knowledge structures used to explain phenomena. They interact with social environments and evolve with the interaction. Lacking daily experience with phenomena, the social interaction gains much more importance. In this part of our multiphase study, we investigate how instructional interactions influenced students’ mental models about the quantization of physical observables. Class observations and interviews were analysed by studying students’ mental models constructed in a modern physics course during an academic semester. The research revealed that students’ mental models were influenced by (1) the manner of teaching, including instructional methodologies and content specific techniques used by the instructor, (2) order of the topics and familiarity with concepts, and (3) peers.

Introductory courses covering modern physics sometimes introduce some elementary ideas from general relativity, though the idea of a geodesic is generally limited to shortest Euclidean length on a curved surface of two spatial dimensions rather than extremal aging in spacetime. It is shown that Epstein charts provide a simple geometric picture of geodesics in one space and one time dimension and that for a hypothetical uniform gravitational field, geodesics are straight lines on a planar diagram. This means that the properties of geodesics in a uniform field can be calculated with only a knowledge of elementary geometry and trigonometry, thus making the calculation of some basic results of general relativity accessible to students even in an algebra-based survey course on physics

The process of developing prescribed curricula has been subject to little empirical investigation, and there have been few attempts to develop theoretical frameworks for understanding the shape and content of particular subjects. This paper presents an account of the author's experience of developing a new course for school physics in the State of Victoria, Australia, at the end of the 1980s. The course was to represent a significant departure from traditional physics courses, and was intended to broaden participation and improve the quality of student learning. In the event the new course turned out to be very similar to traditional courses in Physics. The paper explores the reasons for this outcome. Some powerful discursive mechanisms are identified and some implications of post-structuralism for the theoretical understanding of curriculum are discussed.

Full Text Available Purpose: studying of attitude of students to the existing system of physical education in higher educational institutions of Ukraine and an assessment of possible consequences of implementation of the order of MES of January 26, 2015 No. 47 and the corresponding explanations and recommendations to it which are stated in the letter of MES No. 1/9-1126 of 13.03.2015. Material & Methods: the poll of students of 1–4 courses (n=757 of one of the faculties of Law University named after Yaroslav the Wise (NLU was conducted for the achievement of the stated purpose. Health cards of students, log-books of educational work on physical training of students, log-books of work of sports and improving sections were also analyzed. Results: interest in classes by physical exercises decreases at the vast majority of students during training in higher educational institutions. 88,6% of students note a need of carrying out classes on discipline "Physical education" for higher educational institutions. The majority of them (80,2% will choose discipline "Physical education" if it will be optionally, and 71,9% understand that they need to be engaged in physical exercises 4-6 hours per week for maintenance of the appropriate level of their physical health. Conclusions: the positive result of functioning of the existing system of physical training of student’s youth will be shown that interest in classes by physical exercises decreases at the vast majority of students during training. The effective modernization of the system of physical training of student youth is possible, first, due to use of the existing gender distinctions in interests in classes by physical exercises at students. Secondly, due to properly organized classes with the students who are for health reasons to preparatory (10,9%, special (19,1% medical groups and MPC groups (3,4%. The considerable issues will appear with visit of such classes by students in case of a removal of classes on physical

Full text: The plans of physical protection of nuclear facilities must be reviewed and updated every two years. A general study of the physical protection system was carried out in order to review and to update the plan of physical protection of IPEN-CNEN/SP. Important alterations accomplished at the institute were considered in the study, as the installation of a cyclotron 30 MeV and the new operation conditions for the nuclear research reactor IEA-RI, that include the increase of its operation power from two to five megawatts and the establishment of the continuous operation by 72 hours weekly. The area of IPEN-CNEN/SP is 478,000 m 2 (101,850 m 2 built area of 107 constructions). The group responsible for the study investigated the performance of the physical protection system and detected some points that could be reinforced at inner and protected areas. The initial step was the evaluation, in loco, of the constructions and physical barriers of inner and protected areas. The performance of the security force personnel on the conventional procedures, as access control to the facilities, control of material flow, area monitoring and patrol, as well as its response for special situation procedures in the case of a physical protection emergency, were evaluated too. The study also focused the communication means used by the security force, as the extension phone lines that are located in each entrance area and in the huts, and the portable VHP radios that are used by the guards. In order to elaborate a programme of modernization of the physical protection system, using the results of the study as basis, an internal committee composed of specialists in physical protection, nuclear safety, operation of reactors and engineering areas was created. The programme elaborated by the committee strengthens the physical protection system by applying the defense in depth concept. At the same time, it attempts to propitiate a balanced protection to minimize the consequences for

When systems theory is carefully applied to the concept of energy, some novel and far-reaching implications for modern physics and complementary medicine emerge. The heart of systems theory is dynamic interactions: systems do not simply act on systems, they interact with them in complex ways. By definition, systems at any level (e.g., physical, biological, social, ecological) are open to information, energy, and matter to varying degrees, and therefore interact with other systems to varying degrees. We first show how resonance between two tuning forks, a classic demonstration in physics, can be seen to reflect synchronized dynamic interactions over time. We then derive how the dynamic interaction of systems in mutual recurrent feedback relationships naturally create dynamic "memories" for their interactions over time. The mystery of how a photon (or electron) "knows" ahead of time whether to function as a particle or wave in the single slit/double slit quantum physics paradigm is potentially solved when energetic interactions inherent in the experimental system are recognized. The observation that energy decreases with the square of distance is shown not to be immutable when viewed from a dynamical energy systems perspective. Implications for controversial claims in complementary and alternative medicine, such as memory for molecules retained in water (homeopathy), remote diagnosis, and prayer and healing, are considered. A dynamical energy systems framework can facilitate the development of what might be termed "relationship consciousness," which has the potential to nurture both the science and spirit of complementary medicine and might help to create integrated medicine.

Indian nuclear power programme started with the two Boiling Water Reactors (BWR) of 210 MWe capacity at Tarapur. Two VVER-1000 MWe reactors which are Pressurized Water Reactors (PWR) of Russian design are being constructed at Kudankulam, Tamilnadu and are expected to be commissioned by end 2008. There may be also a possibility of inducting some western PWRs in future. These reactors belong to the category of light water reactors (LWR). The LWRs are compact and have complex physical characteristics distinctly different from those of the Pressurized Heavy Water Reactors (PHWR) which, currently form the mainstay of our indigenous nuclear power programme. The physics design and analysis capability for the modern LWRs (BWR, PWR and VVER) has been developed at Light Water Reactors Physics Section, BARC. This paper presents the current state of art in this key technology area to meet the physics design and operation challenges when LWRs would be inducted in a major way into the Indian nuclear power programme and commence operating in the coming decades.

Reforming a large lecture modern physics course for engineering majors using a PER-based design
McKagan, S. B.; Perkins, K. K.; Wieman, C. E.
2007-01-01
We have reformed a large lecture modern physics course for engineering majors by radically changing both the content and the learning techniques implemented in lecture and homework. Traditionally this course has been taught in a manner similar to the equivalent course for physics majors, focusing on mathematical solutions of abstract problems. Based on interviews with physics and engineering professors, we developed a syllabus and learning goals focused on content that was more useful to our actual student population: engineering majors. The content of this course emphasized reasoning development, model building, and connections to real world applications. In addition we implemented a variety of PER-based learning techniques, including peer instruction, collaborative homework sessions, and interactive simulations. We have assessed the effectiveness of reforms in this course using pre/post surveys on both content and beliefs. We have found significant improvements in both content knowledge and beliefs compared with the same course before implementing these reforms and a corresponding course for physics majors.
Applications of modern statistical methods to analysis of data in physical science
Wicker, James Eric
Modern methods of statistical and computational analysis offer solutions to dilemmas confronting researchers in physical science. Although the ideas behind modern statistical and computational analysis methods were originally introduced in the 1970's, most scientists still rely on methods written during the early era of computing. These researchers, who analyze increasingly voluminous and multivariate data sets, need modern analysis methods to extract the best results from their studies. The first section of this work showcases applications of modern linear regression. Since the 1960's, many researchers in spectroscopy have used classical stepwise regression techniques to derive molecular constants. However, problems with thresholds of entry and exit for model variables plagues this analysis method. Other criticisms of this kind of stepwise procedure include its inefficient searching method, the order in which variables enter or leave the model and problems with overfitting data. We implement an information scoring technique that overcomes the assumptions inherent in the stepwise regression process to calculate molecular model parameters. We believe that this kind of information based model evaluation can be applied to more general analysis situations in physical science. The second section proposes new methods of multivariate cluster analysis. The K-means algorithm and the EM algorithm, introduced in the 1960's and 1970's respectively, formed the basis of multivariate cluster analysis methodology for many years. However, several shortcomings of these methods include strong dependence on initial seed values and inaccurate results when the data seriously depart from hypersphericity. We propose new cluster analysis methods based on genetic algorithms that overcomes the strong dependence on initial seed values. In addition, we propose a generalization of the Genetic K-means algorithm which can accurately identify clusters with complex hyperellipsoidal covariance

In response to an increasing interest in experiments conducted at deep underground facilities around the world, in 2010 the theory community has proposed a new initiative - a Center for Theoretical Underground Physics and Related Areas (CETUP*). The main goal of CETUP* is to bring together people with different talents and skills to address the most exciting questions in particle and nuclear physics, astrophysics, geosciences, and geomicrobiology. Scientists invited to participate in the program do not only provide theoretical support to the underground science, they also examine underlying universal questions of the 21^{st} century including: What is dark matter?, What are the masses of neutrinos?, How have neutrinos shaped the evolution of the universe?, How were the elements from iron to uranium made?, What is the origin and thermal history of the Earth? The mission of the CETUP* is to promote an organized research in physics, astrophysics, geoscience, geomicrobiology and other fields related to the underground science via individual and collaborative research in dynamic atmosphere of intense scientific interactions. Our main goal is to bring together scientists scattered around the world, promote the deep underground science and provide a stimulating environment for creative thinking and open communication between researches of varying ages and nationalities. CETUP*2014 included 5 week long program (June 24 – July 26, 2013) covering various theoretical and experimental aspects of Dark Matter, Neutrino Physics and Astrophysics. Two week long session focused on Dark Matter (June 24-July 6) was followed by two week long program on Neutrino Physics and Astrophysics (July 15-26).

For last six years Center for Theoretical Underground Physics and Related Areas (CETUP*) successfully provided a stimulating environment for creative thinking and open communication between researches of varying ages and nationalities in dynamic atmosphere of intense scientific interactions. Ongoing and proposed Neutrino and Dark Matter experiments are expected to unveil the answers to fundamental questions about the Universe. CETUP*2016 was focused exactly on these subjects bringing together experts in dark matter, neutrino physics, particle and nuclear physics, astrophysics and cosmology from around the world. Scientists invited to participate in the program not only provided theoretical support to the underground science, but they also examined core questions including: What is the nature of dark matter?, What is the origin of the neutrino masses?, How well do we know the neutrino parameters?, How have neutrinos shaped the evolution of the universe?, , What are the fundamental underlying symmetries of the Universe? Is there a Grand Unified Theory of the Universe? and many others. The 2016 CETUP* summer program consisted of three sessions (June 6 – July 16, 2016) covering various aspects of theoretical and experimental neutrino physics, unification and dark matter. The two week long session on Physics and Instrumentation of the Near Detector for the Long-Baseline Neutrino Experiments (June 6 – June 16) was followed by the two week long Neutrino Physics/Unification session: “From Grand Unification to String Theory and Back” (June 20 – July 2). The program ended with two week long session on Dark Matter Physics (July 4 – July 16). This six-week long program allowed for thorough discussions and an effective and comprehensive analysis of topics related to Dark Matter, Dark Energy, Neutrino Physics including astrophysical neutrinos, near and far detector physics, neutrino interactions, Higgs Boson, Inflation, Leptogenesis and many others that will advance
Modern differential geometry for physicists

1989-01-01
These notes are the content of an introductory course on modern, coordinate-free differential geometry which is taken by the first-year theoretical physics PhD students, or by students attending the one-year MSc course "Fundamental Fields and Forces" at Imperial College. The book is concerned entirely with mathematics proper, although the emphasis and detailed topics have been chosen with an eye to the way in which differential geometry is applied these days to modern theoretical physics. This includes not only the traditional area of general relativity but also the theory of Yang-Mills fields
Assessment of Student Learning in Modern Experiments in the Introductory Calculus-Based Physics Labs
Woodahl, Brian; Ross, John; Lang, Sarah; Scott, Derek; Williams, Jeremy
2010-10-01
With the advent of newer microelectronic sensors it's now possible to modernize introductory physics labs with the latest technology and this may allow for enhanced student participation/learning in the experiments. For example, force plate sensors can digitize and record the force on an object, later it can be analyzed in detail (i.e, impulse from force vs. time). Small 3-axis accelerometers can record 3-dim, time-dependent acceleration of objects undergoing complex motions. These devices are small, fairly easy to use, and importantly, are likely to enhance student learning by ``personalizing'' data collection, i.e. making the student an active part of the measurement process and no longer a passive observer. To assess whether these new high-tech labs enhance student learning, we have implemented pre- and post- test sessions to measure the effectiveness of student learning. Four of our calculus-based lab sections were used: Two sections the control group, using the previous ``old technology'' labs, the other two, the experimental group, using the new ``modern technology'' labs. Initial returns of assessment data offer some surprising insight.
International School of Physics Enrico Fermi : Course 190 : Frontiers in Modern Optics

2016-01-01
The year 2015 was designated by the United Nations General Assembly as the Year of Light and Light-based Technologies, and also marks the anniversaries of a number of significant historical events related to light. In 1015, Ibn Al-Haytham published his book of optics; in 1815, Fresnel first proposed the notion that light is actually a wave; James Clerk Maxwell then firmly established this concept with his electromagnetic theory of light propagation; and Einstein announced his discovery of the photoelectric effect, demonstrating that light is made of photons in 1905, followed in 1915 by his general theory of relativity, in which light plays a central role. This book presents lectures from the International School of Physics Enrico Fermi summer school: Frontiers in Modern Optics, held in Varenna, Italy, in June and July 2014. The school attempted to give a broad and modern overview of the field of optics in a series of lectures addressing ongoing topics of research. Subject areas include: nonlinear optics; lig...

Full Text Available The problem of evaluation of anthropometric status of young sportsmen is examined with the use of method of indexes and modern pictures of somatic health of man. In research young boxers took part 10-11 (n=41, 12-13 (n=48 and 14-16 years (n=39. Contradiction and ambiguousness of estimations of physical development of children and teenagers is rotined by means of traditional indexes of Erismana, Quetelet, Pin'e, sthenic and development of thorax. It is marked that an estimation of physical development of children and teenagers with the use of standard deviation of selection is not productive, because in most cases distributing of the studied signs falls short of a normal law. A concept «norm» is recommended to replace a concept «norm» as an obligatory requirement of the state to the level of somatic health of children and teenagers of different regions of country. It is marked that it is expedient to examine physical development of individuals as a structural element of bodily condition the major components of which are indexes of power and capacity of mechanisms of energy supply.
The gatekeepers of modern physics: periodicals and peer review in 1920s Britain.
Clarke, Imogen
2015-03-01
This essay analyzes the processes behind the publication of physics papers in two British journals in the 1920s: the Proceedings of the Royal Society of London: Series A and the Philosophical Magazine. On the surface, it looked as though the Philosophical Magazine was managed very informally, while the Proceedings had in place a seemingly rigid system of committee approval and peer review. This essay shows, however, that in practice the two journals were both influenced by networks of expertise that afforded small groups of physicists considerable control over the content of these prestigious scientific publications. This study explores the nature of peer review, suggesting how a historical approach can contribute to contemporary debates. In studying these relationships, the essay also considers the interplay of "classical" and "modern" ideas and physicists in 1920s Britain and cautions against an anachronistic approach to this classification.

Orekhova, E M; Konchugova, T V; Kul'chitskaya, D B; Korchazhkina, N B; Egorova, L A; Chuich, N G
2016-01-01
The development and introduction into clinical practice of non-pharmacological methods for the prevention and treatment of arterial hypertension is a primary objective of modern physical therapy, especially as regards the neurotropic influences. This article was designed to report the results of the investigation into the hypotensive effect of transcerebral magnetic therapy obtained during the treatment of 60 patients presenting with arterial hypertension. The study included the comparative examination of two randomly formed groups containing 30 patients each. The patients of the main group received transcerebral magnetic therapy (to the frontal region) while those in the group of comparison were given magnetotherapy at the collar region. The study has demonstrated that transcerebral magnetic therapy given to the patients of the main group was a more efficient treatment than magnetotherapy at the collar region since it produced a more pronounced hypotensive effect irrespective of the initial hemodynamic type.

Diosi, Lajos
2011-01-01
This short and concise primer takes the vantage point of theoretical physics and the unity of physics. It sets out to strip the burgeoning field of quantum information science to its basics by linking it to universal concepts in physics. An extensive lecture rather than a comprehensive textbook, this volume is based on courses delivered over several years to advanced undergraduate and beginning graduate students, but essentially it addresses anyone with a working knowledge of basic quantum physics. Readers will find these lectures a most adequate entry point for theoretical studies in this field. For the second edition, the authors has succeeded in adding many new topics while sticking to the conciseness of the overall approach. A new chapter on qubit thermodynamics has been added, while new sections and subsections have been incorporated in various chapter to deal with weak and time-continuous measurements, period-finding quantum algorithms and quantum error corrections. From the reviews of the first edition: ''The best things about this book are its brevity and clarity. In around 100 pages it provides a tutorial introduction to quantum information theory, including problems and solutions.. it's worth a look if you want to quickly get up to speed with the language and central concepts of quantum information theory, including the background classical information theory.''

Each chapter contains relevant information on the scientist''s childhood, research, discoveries, and lasting contributions to the field and concludes with a chronology and a list of print and Internet references specific to that individual.
First Glossary of Modern Physics and Ionising Radiation Protection in Croatian
International Nuclear Information System (INIS)
Nodilo, M.; Petkovic, T.
2011-01-01
Motivation and encouragement for the Glossary were given as the research theme for the joint seminar between the Faculty of Electrical Engineering and Computing and Rudjer Boskovic Institute, within a postgraduate course subject ''Detectors and electronic instrumentation for particle physics''. A basic motivation is due to a lack of specialized literature in Croatian language in the field of protection of ionising radiation as well as the incompleteness of Croatian terminology in the same field. That is a general problem all over the World because the most glossaries are usually connected either with nuclear power plants or with an application of ionising radiation in medicine. On the other hand, a necessity for the specialized literature for radiation protection which follows a development of modern particle physics and its detection technique is rapidly growing up. A work and development on the Glossary were faced with serious difficulties, since various translations of foreign words and acronyms have already been used by various authors in Croatian literature. Different interpretations of the same term or concept, from diverse sources, had to be very often reconciled. However, the biggest challenge was finding proper Croatian words for the foreign terms, concepts, properties, and quantities which have not yet been commonly used so far in Croatian papers or/and Croatian legislative acts. According to our knowledge this seems to be the first comprehensive Glossary, describing the field of ionising radiation protection and bringing of 300 related entries (terms and guidelines). That is, certainly, the first characteristic Thesaurus in Croatian which includes background of modern physics and chemistry, particle phenomenology and its measurement, all dedicated to the radiological protection of workers, environment and people of the World. A Glossary brings a wide spectrum of terms of broad area of chemistry, radiation protection, nuclear and particle physics. A

In 1946 Philip (Phil) Russell Wallace joined the Mathematics Department of McGill University as an Associate Professor of Applied Mathematics, apparently because A. H. S. Gillson, Dean of Arts and Science, wanted theoretical physicists to be in the Mathematics Department. He came with the dream of creating a theoretical physics group at McGill. By the spring of 1949, Phil was authorized to recruit two junior faculty in Mathematics. He hired Theodore (Ted) F. Morris from U. Toronto, who joined in September 1949, and me, who came in January 1950. The group had begun. Phil Wallace was born in Toronto in 1915 and grew up there. He entered the University of Toronto in 1933, earned a B.A. in mathematics in 1937, a M.A. in 1938, and a Ph.D. in applied mathematics in 1940 under Leopold Infeld. His Ph.D. thesis in general relativity was entitled 'On the relativistic equations of motion in electromagnetic theory.' In 1940 World War II had engulfed Europe and was having its effect on Canada, but the US was still at peace. L. J. Synge, Head of the Applied Mathematics Department at Toronto, told Wallace that people such as he would be needed in war work, but things were not ready quite yet. Hold yourself ready. Phil took a two-year position as lecturer in mathematics at the University of Cincinnati (1940-42); in the fall of 1942 he became a lecturer in mathematics at M.I.T. It was from there that he was recruited by Synge to join the war effort from 1943 to 1946 at N.R.C.'s Montreal Laboratory, the genesis of the Canadian Atomic Energy Project. Phil has described those heady wartime years in these pages. Much of the effort of the theoretical physicists was on nuclear reactor theory and the properties of relevant materials, such as graphite, under long and intense neutron bombardment. In late 1945 Phil was sent for four months to Bristol to learn about the properties of graphite from the esteemed N. F. Mott. This exposure led Phil to a life-long interest in graphite and in

This report describes the accomplishments in basic research in nuclear physics carried out by the theoretical nuclear physics group in the Department of Physics at the University of Texas at Austin, during the period of April 1, 1993 to March 31, 1996. The work done covers three separate areas, low energy nuclear reactions, intermediate energy physics, and nuclear structure studies. Although the various subjects are spread among different areas, they are all based on two techniques that they have developed in previous years. These techniques are: (a) a powerful method for continuum-random-phase-approximation (CRPA) calculations of the nuclear response; and, (b) the direct reaction approach to complete and incomplete fusion reactions, which enables them to describe on a single footing all the different types of nuclear reactions, i.e., complete fusion, incomplete fusion and direct reactions, in a systematic way based on a single theoretical framework. In this report, the authors first summarize their achievements in these three areas, and then present final remarks
Theoretical nuclear physics in France: overview and perspectives - 2004 and 2009
International Nuclear Information System (INIS)
2004-11-01
A first report published in 2004 proposes an overview of the situation of research in theoretical nuclear physics in France per field of research: nucleus structure, nuclear reactions at low and medium energies (fusion, fission, multi fragmentation), hadron physics, state equation of nuclear matter and of neutron matter, and nuclear astrophysics, plasma of quarks and gluons, and nucleus-nucleus collisions at high energy, developments of the theory of the nuclear N-body problem and its impact on other disciplines. For each theme, the report indicates the involved research themes and their specific fields of research, comments the research themes, objectives and perspectives, discusses how the theoretical activity matches experimental programmes. The second report published in 2009 proposes the same kind of overview for the following themes: nucleus structure, state equation of nuclear and stellar matter, collisions and reactions at low and medium energy, hadron physics, quarks and gluons in nuclear physics, interdisciplinary applications of nuclear theory. Each report also provides some statistics about the researcher community

The Large Hadron Collider at CERN is moving the experimental frontier of particle physics to the domain of electroweak symmetry breaking, reaching energies around one trillion electron volts for collisions among the basic constituents of matter. We do not know what the new wave of exploration will find, but the discoveries we make and the new puzzles we encounter are certain to change the face of particle physics and echo through neighboring sciences. In this new world, we confidently expect to learn what sets electromagnetism apart from the weak interactions, with profound implications for deceptively simple questions: Why are there atoms? Why chemistry? What makes stable structures possible? A pivotal step will be finding the Higgs boson-or whatever takes its place -and exploring its properties. But we hope for much more. More predictive extensions of the electroweak theory, including dynamical symmetry breaking and supersymmetry, imply new kinds of matter that would be within reach of LHC experiments. We suspect that candidates for the dark matter of the Universe could also await discovery on the TeV scale. The strong interactions may hold their own surprises. As we unravel the riddle of electroweak symmetry breaking, prospects arise for other new insights: into the different forms of matter, the unity of quarks and leptons, and the nature of spacetime. The questions in play all seem linked to one another-and to the kinship of the weak and electromagnetic interactions. I will speak of the evolving dialogue between theory and experiment, highlighting the work before us. Fermilab is operated by the Fermi Research Alliance under contract no.

Women in Physics in Australia as the Expectations of the Modern Researcher Change
Foley, C. P.
2009-04-01
Publicly funded science, which employs the majority of research scientists in Australia, has since 1988 had significant shifts in the basis for funding with the expectation that all research, regardless of how fundamental, should have a plan or potential for impact for the community's benefit. This may be solving major problems for Australia (e.g., climate change and provision of water and energy) to creating new technologies and industries to boost the Australian economy. At the same time, there has been some improvement in the status of women in science in Australia. There is recognition that women bring diversity to research teams, making teams more effective, and this is being embraced. However, other issues are still creating difficulties for women from the drop in the quality of child care while its costs increase; the need to juggle family and career, particularly balancing the need for travel; the poorly paid maternity leave provisions; and the difficulty in restarting a career in science if time is taken out for child rearing. The changing expectations of the modern researcher, the status of women in Australian physics as a specific example, and the issues that are limiting women's opportunities in a ``well meaning'' culture that does not realize the limitations it is creating are reported, along with what the Australian Institute of Physics is doing to overcome them.

This paper aims at closing a gap in recent Weyl research by investigating the role played by Leibniz for the development and consolidation of Weyl's notion of theoretical (symbolic) construction. For Weyl, just as for Leibniz, mathematics was not simply an accompanying tool when doing physics-for him it meant the ability to engage in well-guided speculations about a general framework of reality and experience. The paper first introduces some of the background of Weyl's notion of theoretical construction and then discusses particular Leibnizian inheritances in Weyl's 'Philosophie der Mathematik und Naturwissenschaft', such as the general appreciation of the principles of sufficient reason and of continuity. Afterwards the paper focuses on three themes: first, Leibniz's primary quality phenomenalism, which according to Weyl marked the decisive step in realizing that physical qualities are never apprehended directly; second, the conceptual relation between continuity and freedom; and third, Leibniz's notion of 'expression', which allows for a certain type of (surrogative) reasoning by structural analogy and which gave rise to Weyl's optimism regarding the scope of theoretical construction.

1984-09-01
The Subpanel on Theoretical Computing of the High Energy Physics Advisory Panel (HEPAP) was formed in July 1984 to make recommendations concerning the need for state-of-the-art computing for theoretical studies. The specific Charge to the Subpanel is attached as Appendix A, and the full membership is listed in Appendix B. For the purposes of this study, theoretical computing was interpreted as encompassing both investigations in the theory of elementary particles and computation-intensive aspects of accelerator theory and design. Many problems in both areas are suited to realize the advantages of vectorized processing. The body of the Subpanel Report is organized as follows. The Introduction, Section I, explains some of the goals of computational physics as it applies to elementary particle theory and accelerator design. Section II reviews the availability of mainframe supercomputers to researchers in the United States, in Western Europe, and in Japan. Other promising approaches to large-scale computing are summarized in Section III. Section IV details the current computing needs for problems in high energy theory, and for beam dynamics studies. The Subpanel Recommendations appear in Section V. The Appendices attached to this Report give the Charge to the Subpanel, the Subpanel membership, and some background information on the financial implications of establishing a supercomputer center

Cyber physical computing infrastructures typically consist of a number of sites are interconnected. Its operation critically depends both on cyber components and physical components. Both types of components are subject to attacks of different kinds and frequencies, which must be accounted for the initial provisioning and subsequent operation of the infrastructure via information security analysis. Information security analysis can be performed using game theory implemented in dynamic Agent Based Game Theoretic (ABGT) simulations. Such simulations can be verified with the results from game theory analysis and further used to explore larger scale, real world scenarios involving multiple attackers, defenders, and information assets. We concentrated our analysis on the electric sector failure scenarios and impact analyses by the NESCOR Working Group Study, From the Section 5 electric sector representative failure scenarios; we extracted the four generic failure scenarios and grouped them into three specific threat categories (confidentiality, integrity, and availability) to the system. These specific failure scenarios serve as a demonstration of our simulation. The analysis using our ABGT simulation demonstrates how to model the electric sector functional domain using a set of rationalized game theoretic rules decomposed from the failure scenarios in terms of how those scenarios might impact the cyber physical infrastructure network with respect to CIA.
Theoretical Studies of Alfven Waves and Energetic Particle Physics in Fusion Plasmas

This report summarizes major theoretical findings in the linear as well as nonlinear physics of Alfvén waves and energetic particles in magnetically confined fusion plasmas. On the linear physics, a variational formulation, based on the separation of singular and regular spatial scales, for drift-Alfvén instabilities excited by energetic particles is established. This variational formulation is then applied to derive the general fishbone-like dispersion relations corresponding to the various Alfvén eigenmodes and energetic-particle modes. It is further employed to explore in depth the low-frequency Alfvén eigenmodes and demonstrate the non-perturbative nature of the energetic particles. On the nonlinear physics, new novel findings are obtained on both the nonlinear wave-wave interactions and nonlinear wave-energetic particle interactions. It is demonstrated that both the energetic particles and the fine radial mode structures could qualitatively affect the nonlinear evolution of Alfvén eigenmodes. Meanwhile, a theoretical approach based on the Dyson equation is developed to treat self-consistently the nonlinear interactions between Alfvén waves and energetic particles, and is then applied to explain simulation results of energetic-particle modes. Relevant list of journal publications on the above findings is also included.

L.G. Ramensky (1884-1953) was an outstanding Soviet geobotanist of the first part of XX century. Considered is his theoretical legacy and its contribution to modern vegetation science. L.G. Ramensky formulated the principle of vegetation continuum based on which the modern paradigm of vegetation science has been put into shape. The scientist made a contribution to the development of such important theoretical conceptions as types of plant strategy, coenosis and coenobiosis (coexistence of species), patterns of interannual variability in plant communities, ecological successions. The unique ecological scales were established by L.G. Ramensky that characterize the distribution of 1400 species over the gradients of soil moistening, richness, and salinization as well as moistening variability, pastoral digression, and alluvial intensity. He came out against mechanistic notions by V.N. Sukachev on a biogeocoenosis structure. The scientist did not offer his own method of plant communities classification but his well-reasoned criticism of dominant classification played a great role in adoption of floristical classification principles (Braun-Blanquet approach) by phytocenology in our country.

While co-citation analysis has proved a powerful tool in the study of changes in intellectual foci in science, no one has ever used the technique to study very rapid changes in the theoretical structure of a scientific field. This paper presents month-by-month co-citation analyses of key phases in the weak-electromagnetic unification research program within particle physics, and shows that these analyses capture and illuminate very rapid intellectual changes. These data provide yet another illustration of the utility of co-citation analysis for understanding the history of science. 8 figures

Studies of Credit and Equity Markets with Concepts of Theoretical Physics
Münnix, Michael C
2011-01-01
Financial markets are becoming increasingly complex. The financial crisis of 2008 to 2009 has demonstrated that an improved understanding of the mechanisms embedded in the market is a key requirement for the estimation of financial risk. Recently, concepts of theoretical physics, in particular concepts of complex systems, have proven to be very useful in this regard. Michael C. Münnix analyses the statistical dependencies in financial markets and develops mathematical models using concepts and methods from physics. The author focuses on aspects that played a key role in the emergence of the recent financial crisis: estimation of credit risk, dynamics of statistical dependencies, and correlations on small time-scales. He visualizes the findings for various large-scale empirical studies of market data. The results give novel insights into the mechanisms of financial markets and allow conclusions on how to reduce financial risk significantly.

In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of non-linear and dispersive effects in the medium. In this book, the authors discuss the interactions and theoretical and experimental challenges of solitons. Topics include soliton motion of electrons and its physical properties in coupled electron-phonon systems and ionic crystals; soliton excitations and its experimental evidence in molecular crystals; shapes and dynamics of semi-discrete solitons in arrayed and stacked waveguiding systems; ion-acoustic super solitons in plasma; diamond-controlled solitons and turbulence in extracellular matrix and lymphatic dynamics; and non-linear waves in strongly interacting relativistic fluids.

In 1995 the DOE grant in Nuclear theory with Professors Rubin H. Landau and Victor A. Madsen as co-principal investigators ended. Their research was carried out in collaboration with graduate students in Corvallis, and with scientists at LLNL-Livermore, Los Alamos, TRIUMF, KFA-Julich, Hamburg University, Melbourne University, The Thinking Machine Corporation and IBM Research. Activities in nuclear and particle physics at Oregon State University (OSU) were diverse and active. Madsen's work concentrated on the relation of reactions to the nuclear structure, and Landau's work concentrated on intermediate energy physics, few-body problems, and computational physics. The Landau group had a weekly meeting of students and visitors. There was a weekly nuclear seminar with experimental and theoretical colleagues, and a weekly departmental colloquium. The DOE support had permitted the group to run Unix workstations networked to other computers in the Physics Department and the University. Since 1990 OSU has been using IBM RISC System 6000/model 530 with console and four X-stations. The equipment was purchased and is maintained with yearly DOE funding of the group

A design study was completed to explore the theoretical physical capacity (TPC) of the John F. Kennedy International Airport (KJFK) runway system for a northflow configuration assuming impedance-free (to throughput) air traffic control functionality. Individual runways were modeled using an agent-based, airspace simulation tool, the Airspace Concept Evaluation System (ACES), with all runways conducting both departures and arrivals on a first-come first-served (FCFS) scheduling basis. A realistic future flight schedule was expanded to 3.5 times the traffic level of a selected baseline day, September 26, 2006, to provide a steady overdemand state for KJFK runways. Rules constraining departure and arrival operations were defined to reflect physical limits beyond which safe operations could no longer be assumed. Safety buffers to account for all sources of operational variability were not included in the TPC estimate. Visual approaches were assumed for all arrivals to minimize inter-arrival spacing. Parallel runway operations were assumed to be independent based on lateral spacing distances. Resulting time intervals between successive airport operations were primarily constrained by same-runway and then by intersecting-runway spacing requirements. The resulting physical runway capacity approximates a theoretical limit that cannot be exceeded without modifying runway interaction assumptions. Comparison with current KJFK operational limits for a north-flow runway configuration indicates a substantial throughput gap of approximately 48%. This gap may be further analyzed to determine which part may be feasibly bridged through the deployment of advanced systems and procedures, and which part cannot, because it is either impossible or not cost-effective to control. Advanced systems for bridging the throughput gap may be conceptualized and simulated using this same experimental setup to estimate the level of gap closure achieved.

Materials Protection, Control and Accounting (MPC and A) equipment upgrades are complete at the Institute of Theoretical and Experimental Physics (ITEP), a site that has significant quantities of weapons-potential nuclear materials. Cooperative work was initiated at this Moscow facility as a part of the US-Russian program to upgrade MPC and A systems. An initial site visit and assessment were conducted in September 1996 to establish communication between ITEP, the US Department of Energy (DOE), and participating US National Laboratories. Subsequently, an agreement was reached to develop two master plans for MPC and A upgrades. Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (ORNL) assisted in developing a plan for Material Control and Accounting (MC and A) upgrades, and Sandia National Laboratories (SNL) assisted in developing a plan for Physical Protection System (PPS) upgrades. The MC and A plan included MC and A training, a mass measurement program, nondestructive assay instrumentation, item identification (bar coding), physical inventory taking, portal and hand-held nuclear material monitors, and a nuclear materials accounting system. The PPS plan included basic PPS design training, Central Alarm Station (CAS) relocation and equipment upgrades, a site and critical-building access control system, intrusion detection, alarm assessment, and guard force communications

Since these alkaloids have established biochemical profile, related the binding affinity of the nicotinic acetylcholine receptors (nAChRs), particularly α7 sub-type, the presented correlation between the molecular structure and properties allowed to evaluated the highlights of the biochemical hypothesises related the Schizophrenia. The anticancer activity of α7 subtype agonists and the crucial role of the nucleoside-based medications in the cancer therapy provided opportunity for further study on the biochemical relationship between Schizophrenia and few kinds of cancers, which has been hypothesized recently. The physical electronic absorptions (EAs), circular dichroic (CD) and Raman spectroscopic (RS) properties as well as mass spectrometric (MS) data, obtained using electrospray ionization (ESI) and atmospheric-pressure chemical ionization (APCI) methods under the positive single (MS) and tandem (MS/MS) modes of operation are discussed. Taking into account reports on a fatal intoxication of Cyt, the presented data would be of interest in the field of forensic chemistry, through development of highly selective and sensitive analytical protocols. Quantum chemical method is used to predict the physical properties of the isolated alkaloids, their affinity to the receptor loop and gas-phase stabilized species, observed mass spectrometrically.

In this work we have developed a new method for calculating the physical properties of heavy water, D 2 O, using the Helmholtz free energy state function, A = U − T S, exclusively for this molecule. The state function has been calculated as ā = ā 0 +ā 1 (specific dimensionless values), where ā 0 is related to the properties of heavy water in gaseous state and ā 1 describes the liquid state. The canonical variables of the state function are absolute temperature and volume. To calculate the physical properties defining absolute pressure and temperature, here a variable change method was developed, based on the solution of a differential equation (function ζ) using numerical algorithms (scaling and Newton-Raphson). Physical quantities calculated are: density ϱ(specific volume υ), specific enthalpy h and entropy s. The results obtained agree completely with the values calculated by the National Institute of Standards and Technology (NIST). In this report it has also proposed an adjustment function to calculate the saturation absolute temperature of heavy water as a function of the pressure: T s (p) = exp[a·b(p)], where a is a vector of constant coefficients and b a vector function of pressure, using theoretical values and extending the wording proposed by the Oak Ridge National Laboratory. The new setting has an error less than 0.03%. (author)

Ever since Dirac predicted the existence of antimatter in 1928, it has excited our collective imagination. Seventy-four years later, two collaborations at CERN, ATHENA and ATRAP, created the first slow antihydrogen. This was a stunning achievement, but the most important antimatter experiments require trapped, not just slow, antihydrogen. The velocity, magnetic moment, and internal energy and state of the antihydrogen depend strongly on how it is formed. To trap antihydrogen, physicists face two broad challenges: (1) Understanding the behavior of the positron and antiprotons plasmas from which the antihydrogen is synthesized; and (2) Understanding the atomic processes by which positrons and antiprotons recombine. Recombination lies on the boundary between atomic and plasma physics, and cannot be studied properly without employing tools from both fields. The proposed collaborative research campaign will address both of these challenges. The collaboration members have unique experience in the relevant fields of experimental and theoretical non-neutral plasma physics, numerical modeling, nonlinear dynamics and atomic physics. This expertise is not found elsewhere amongst antihydrogen researchers. The collaboration members have strong ties already, and seek to formalize them with this proposal. Three of the four PIs are members of the ALPHA collaboration, an international collaboration formed by most of the principal members of the ATHENA collaboration.

The operation of cyber infrastructures relies on both cyber and physical components, which are subject to incidental and intentional degradations of different kinds. Within the context of network and computing infrastructures, we study the strategic interactions between an attacker and a defender using game-theoretic models that take into account both cyber and physical components. The attacker and defender optimize their individual utilities, expressed as sums of cost and system terms. First, we consider a Boolean attack-defense model, wherein the cyber and physical subinfrastructures may be attacked and reinforced as individual units. Second, we consider a component attack-defense model wherein their components may be attacked and defended, and the infrastructure requires minimum numbers of both to function. We show that the Nash equilibrium under uniform costs in both cases is computable in polynomial time, and it provides high-level deterministic conditions for the infrastructure survival. When probabilities of successful attack and defense, and of incidental failures, are incorporated into the models, the results favor the attacker but otherwise remain qualitatively similar. This approach has been motivated and validated by our experiences with UltraScience Net infrastructure, which was built to support high-performance network experiments. The analytical results, however, are more general, and we apply them to simplified models of cloud and high-performance computing infrastructures. © 2015 Society for Risk Analysis.

The medical application of ionizing radiation has the longest history, the most extensive uses and the strongest effect among the multiple applications of ionizing radiation technology. With the development of diagnostic radiology and radiotherapy, for instances, the radiology, the interventional radiology, the nuclear medicine, and the radiation oncology; the infrastructures and teambuilding of medical physics in China has been becoming more and more important and urgent. Fortunately, people in relevant fields have already recognized this situation and made lots of progresses in the recent years, for example, the 221 st Xiangshan Science Conference took 'The Development of Medical Physics' as its main topic in 2004; in recent years, a series of regulations and national standards regarding to the quality assurance and radiological protection of medical exposure and the teambuilding of the relevant departments in hospital have been successively issued; the subject of Medical Physics was opened as both undergraduate and graduated courses in more and more universities (Tsinghua University, Peking University etc); the Committee on Medical Physics was enrolled as a new member of the Chinese Physical Society. Modern medical physics should include 4 parts, medical imaging physics, nuclear medicine physics, radiation oncology physics, and health physics. Protection against ionizing radiation needs to fully cover the development of medical physics, which includes the protection against ianizing radiation in medical uses. This article emphasizes the improvement of the ionizing radiation protection in medical uses, for marking of 30th anniversary of the Journal of Radiation Protection. (authors)

The aim of this book is to present highly accurate and extensive theoretical Atomic data and to give a survey of selected calculational methods for atomic physics, used to obtain these data. The book presents the results of calculations of cross sections and probabilities of a broad variety of atomic processes with participation of photons and electrons, namely on photoabsorption, electron scattering and accompanying effects. Included are data for photoabsorption and electron scattering cross-sections and probabilities of vacancy decay formed for a large number of atoms and ions. Attention is also given to photoionization and vacancy decay in endohedrals and to positron-atom scattering. The book is richly illustrated. The methods used are one-electron Hartree-Fock and the technique of Feynman diagrams that permits to include many-electron correlations. This is done in the frames of the Random Phase approximation with exchange and the many-body perturbation theory. Newly obtained and previously collected atomi...

Historians of medicine, childhood and paediatrics have often assumed that early modern doctors neither treated children, nor adapted their medicines to suit the peculiar temperaments of the young. Through an examination of medical textbooks and doctors' casebooks, this article refutes these assumptions. It argues that medical authors and practising doctors regularly treated children, and were careful to tailor their remedies to complement the distinctive constitutions of children. Thus, this article proposes that a concept of 'children's physic' existed in early modern England. This term refers to the notion that children were physiologically distinct, requiring special medical care. Children's physic was rooted in the ancient traditions of Hippocratic and Galenic medicine: it was the child's humoral make-up that underpinned all medical ideas about children's bodies, minds, diseases and treatments. Children abounded in the humour blood, which made them humid and weak, and in need of medicines of a particularly gentle nature.

Full text: Using national and international recommendations about human resource in Nuclear Medicine, a group of experts organized a National Course for the education and training of physicist who work in Cuban hospitals, adapted to national condition and practice of Nuclear Medicine. The program was approved for National Authorities in Nuclear Security and University Schools in Medicine. The program contains two intensive theoretic and practical courses, to be completed over a period of 15 days of full time engagement, complemented with 4 month full attachment to a Nuclear Medicine Service monitored by accredited expert. The theoretical/practical intensive courses have final evaluation: combining practical exercise and a final test. When all docent activities finish the students should clear a final theoretical/practical evaluation by an examination board comprising of at least three accredited experts. The theoretical/practical courses were attended by 19 physicists working in hospitals in Cuba. The contents of the first course included, Introduction to Nuclear Medicine, Principle of NM equipment, Quality assurance and quality control of NM equipment, Radiation Protection and Licence Topics of NM Services. The second course had the following topics: Acquisition and Processing methods in Nuclear Medicine, Nuclear Medicine Techniques and Clinical Dosimetry for radiopharmaceutical therapy. With 100 point of maximum score and 60 point minimum to pass, the final test of this first course comprised of 2 types of questions: 1 Multiple choice questions and 2. long essay type questions. The average scores obtained by the participants was 87.02 points/ students (range 65- 100 points). The students pass the test with very good degree of comprehension: 10-Excellent (90-100 points), 5- Very good (80-89 points), 2-Good (70-79 point) and 2- satisfactory standard (60-69 point).
