The situation surrounding the Olympiads is paradoxical. On the one hand, considerable resources are spent on the Olympiads. On the other hand, there are widespread arguments about the harm of the Olympiads, often very strange ones. For example, there is a perception that success in the Olympiads has little to do with a scientific career. Sometimes it comes to curious assertions, such as that "there are no Olympiad winners among the eminent mathematical researchers," even though in truth the p...

Now in its third decade, the Colorado Mathematical Olympiad (CMO), founded by the author, has become an annual state-wide competition, hosting many hundreds of middle and high school contestants each year. This book presents a year-by-year history of the CMO from 2004–2013 with all the problems from the competitions and their solutions. Additionally, the book includes 10 further explorations, bridges from solved Olympiad problems to ‘real’ mathematics, bringing young readers to the forefront of various fields of mathematics. This book contains more than just problems, solutions, and event statistics — it tells a compelling story involving the lives of those who have been part of the Olympiad, their reminiscences of the past and successes of the present. I am almost speechless facing the ingenuity and inventiveness demonstrated in the problems proposed in the third decade of these Olympics. However, equally impressive is the drive and persistence of the originator and living soul of them. It is hard fo...

Full Text Available The purpose of the South African Mathematics Olympiad is to generate interest in mathematics and to identify the most talented mathematical minds. Our focus is on how the handling of missing data affects the selection of the ‘best’ contestants. Two approaches handling missing data, applying the Rasch model, are described. The issue of guessing is investigated through a tailored analysis. We present two microanalyses to illustate how missing data may impact selection; the first investigates groups of contestants that may miss selection under particular conditions; the second focuses on two contestants each of whom answer 14 items correctly. This comparison raises questions about the proportion of correct to incorrect answers. Recommendations are made for future scoring of the test, which include reconsideration of negative marking and weighting as well as considering the inclusion of 150 or 200 contestants as opposed to 100 contestants for participation in the final round.

International Science Olympiad participants' experiences and perceptions on private education
Park, Kyeong jin; Ryu, Chun-Ryol; Choi, Jinsu
2016-04-01
The International Science Olympiad is an international intellectual olympic in which students, aging under 20 and who have not entered university, compete using their creative problem solving skills in the field of science. Many nations participate in the Olympiad with great interest, for this competition is a global youth science contest which is also used to measure national basic science levels. However in Korea, benefits for Olympiad participants were reduced because issues were risen that the Olympiad could intensify private education. This resulted in a continuous decrease in the number of applicants, bringing national competitiveness deterioration to concern. Therefore in this study, we identified the problems by analyzing the actual conditions of Olympiad participants' private education, and sought support plans to activate Olympiad participation. For this use, we conducted a survey of 367 summer school and winter school acceptees in 9 branches. 68.9% of the students were preparing for the Olympiad by private education, and the highest percentage answered that their private education expenses were an average of 3~5 million won. Olympiad preparation took up 30~50% of all private education, showing that private education greatly influences the preparing processes for the Olympiad. Meanwhile the participants perceived that in order to reduce Olympiad-related private education, the following should be implemented priority: supply of free high-quality on-line education materials, and easy access to Olympiad related information. It was also suggested that the most effective and needed education methods were school olympiad preparation classes, on-line education expansion, and special lectures and mentoring from olympiad-experienced senior representatives. Additionally, as methods to activate Olympiad participation, it was thought that award records should be allowed to be used in college applications by enabling award records into student records and special

Science Olympiad students' nature of science understandings
Philpot, Cindy J.
2007-12-01
Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in

Wahl, K.
1999-01-01
In an address to the IPPSO IMO Conference May 26, Hydro Mississauga General Manager K. Wahl spoke about what a buyer wants to see in the IMO system. His remarks were framed from the perspective of a buyer (Hydro Mississauga) that purchases approximately 5% of Ontario's electricity output and which is also entering into the generation market through the Lakeview joint venture project. Wahl described four basic expectations that buyers have of the IMO: choice for their customers, market efficiency, transparency, and fairness. To underline the need for transparency, he described how municipal utilities are facing key business decisions that will hinge in part on the IMO. Using Hydro Mississauga as an example, he explained how the utility must: obtain new licenses, form one of more profit oriented businesses, be positioned at market opening with customer contracts and power purchase agreements, choose whether to implement and manage billing transaction or to contract it out, and decide whether to become licensed in the business of wholesale energy trading. Further detail is included concerning the IMO rules and procedures that buyers would like to see: transmission rights for import and export of power, congestion pricing, clear import rules, clarity in extending physical bilateral contracting to retail, information release, identified interface obligations, participant training, and pilot testing

The present study examines the performance of academically talented students (i.e., those who received awards in Olympiads, the international competitions for gifted students in science or mathematics) in medical school. The goal is to investigate whether students exceptionally talented in science and mathematics excel in medical school. A retrospective analysis of 13 cohorts of medical students (N = 475) was conducted to compare learning outcomes of academically talented students (ATS) with their peers in terms of their grade point averages (GPAs) and national licensing exam (KMLE) scores. ATS outperformed their peers in total GPAs (p success in medical school, even among those with exceptional talent. Better understanding of nonacademic factors associated with medical school performance is warranted to improve our selection processes and to better help academically talented students succeed in medical school.

Social cognitive theory guided the design of a survey to investigate high school students' perceptions of factors affecting their career contemplations and beliefs regarding the influence of their participation in the international Science Olympiad on their subject interests and twenty-first century skills. In addition, gender differences in students' choice of competition category were studied. Mixed methods analysis of survey returns from 172 Olympiad participants from 31 countries showed that students' career aspirations were affected most by their teachers, personal interests, and parents, respectively. Students also indicated that they believed that their participation in the Olympiad reinforced their plan to choose a science, technology, engineering, and mathematics (STEM) major at college and assisted them in developing and improving their twenty-first century skills. Furthermore, female students' responses indicated that their project choices were less likely to be in the engineering category and more likely to be in the environment or energy categories. Findings are discussed in the light of increasing the awareness of the role and importance of Science Olympiads in STEM career choice and finding ways to attract more female students into engineering careers.

The 26th International Physics Olympiad: On top down under!
1996-01-01
. Twenty-five countries made an informal commitment to pay towards the cost of students and leaders. Britain is host to the competition in the year 2000 and is looking for sponsors and grants to make it possible. Suddenly it was nearly all over and we were boarding the buses to the Closing Ceremony. We were delighted when Richard Davies was awarded an additional prize for the Best Mathematical Solution. Again the Ceremony was colourful, musical and moving but had its lighter moments when all the gold medallists were given bush hats that swamped some and perched atop others! The Flame of Science was extinguished and we were sitting down for our final meal together - a Banquet! 'Chef' (from North London) had triumphed again, feeding over 600 people excellently. Several countries and the team of examiners gave impromptu entertainment. Many had to board a bus for Sydney at 3 am, but we were allowed a last night's sleep. By the morning the IPhO office had removed itself, leaving a pile of cardboard boxes, and what had seemed a living organism had disappeared. Throughout, we found the Australians so friendly and helpful and the coach drivers were extremely informative. Rod's team of previous Olympiad students (green blazers) and Summer Science School students (blue blazers) had performed their organizational tasks so patiently and efficiently, I'm sure everyone's stay was enjoyable and successful. Thanks to all the companies whose sponsorship made the trip possible. Celia Bloor City of Stoke-on-Trent, Sixth Form College

From 32 countries and international organizations over 100 persons attended SCM. Based on the results of SCM, the following issues were discussed and solved by 2001. INF Code became madatory since the 1st of January 2001 as Part D ''Special requirements for the carriage of packaged irradiated nuclear fuel, plutonium and high-level radioactive wastes on board ships'' of Chapter VII (Carriage of dangerous goods) of ANNEX of the International Convention for the Safety of Life at Seas (SOLAS). Concerning the response to an incident with radioative contamination ''Protocol on preparedness, response and co-operation to pollution incidents by harzardous and noxious substances, 2000'' were established for inter-governmental co-operation, in addition to the pollution manual in the International Convention for the Prevention of Pollution from Ships (MARPOL). In IMO, 'hazardous and noxious substances' are identified in the International Maritime Dangerous Goods Code (IMDG Code). Radioactive substance is one of the eight categories of IMDG Code.

The province of Ontario plans to launch its restructured, competitive wholesale electricity market in the spring of 2002. This Business Plan of the IMO presents a detailed blueprint for its operation following the opening of that market. The report has 8 chapters including a summary and appendices. The chapters deal with many issues including: (1) the 2004 Business Plan in the context of 2002, (2) the IMO business service, (3) performance management, (4) IMO resource requirements and staffing, (5) revenue resources and associated regulatory approvals, and (6) financial policies and Pro Forma statements. The report reflects the evolution of the IMO from a project-based organization to a customer-focused company whose goal is to improve collaboration among market participants. The IMO is seeking approval from the Ontario Energy Board (OEB) for its proposed revenue requirement of $153.9 million and proposed capital expenditure of $66.3 million. The IMO is also seeking approval for a usage fee of $0.959 per MWh that wholesale customers and market participants will have to pay for all energy withdrawn for use or sale under open competition. The IMOs operating costs are comparable to other market operators in the Northeastern United States. tabs., figs

Morteza Ghojazadeh
2015-12-01
Full Text Available Introduction: Due to the importance of holding effective scientific Olympiads for medical sciences students, this study aimed to evaluate experts’ viewpoints in regard to their necessity, costs, achievements, barriers and solutions. Methods: In this qualitative study, required data were collected using open-ended questions through self-development questionnaires, which were filled out by experts. Data were analyzed through content-analysis methods. To select participants, a purpose-based sampling method was applied up to the point of information saturation. Thus, this study was performed with 20 individuals. Results: The main necessity and philosophy of holding Olympiads expressed by the experts were: promoting health sector performance, extension of interrelationships between universities, development of scientific competition and incensement of students’ creativity. The majority of participants believed that the achievements of holding these Olympiads are negligible versus their costs. The most important barriers were: absence of appropriate relationships between universities, lack of proper support for holding these Olympiads, the low motivation of professors, noninterested students and the shortage of resources and facilities. Furthermore, the most important solutions included: performance evaluation of previous Olympiads, increasing incentives and motivations as well as suitable planning. Conclusion: According to experts’ viewpoints, although holding scientific Olympiads is necessary for medical students, during past years, the achievements of such Olympiads versus theirs costs seem negligible and there are lots of barriers in the path of achieving their goals and philosophy.

Design and optimization analysis of dual material gate on DG-IMOS
Singh, Sarabdeep; Raman, Ashish; Kumar, Naveen
2017-12-01
An impact ionization MOSFET (IMOS) is evolved for overcoming the constraint of less than 60 mV/decade sub-threshold slope (SS) of conventional MOSFET at room temperature. In this work, first, the device performance of the p-type double gate impact ionization MOSFET (DG-IMOS) is optimized by adjusting the device design parameters. The adjusted parameters are ratio of gate and intrinsic length, gate dielectric thickness and gate work function. Secondly, the DMG (dual material gate) DG-IMOS is proposed and investigated. This DMG DG-IMOS is further optimized to obtain the best possible performance parameters. Simulation results reveal that DMG DG-IMOS when compared to DG-IMOS, shows better I ON, I ON/I OFF ratio, and RF parameters. Results show that by properly tuning the lengths of two materials at a ratio of 1.5 in DMG DG-IMOS, optimized performance is achieved including I ON/I OFF ratio of 2.87 × 109 A/μm with I ON as 11.87 × 10-4 A/μm and transconductance of 1.06 × 10-3 S/μm. It is analyzed that length of drain side material should be greater than the length of source side material to attain the higher transconductance in DMG DG-IMOS.

Some insight is provided for IPPSO members into the IMO Technical Panel (TP), its scope, modus operandi, and stakeholdering process. The TP is one of 3 panels recommended by the MDC and defined in the IMP bylaws. Its role is to consider rule changes and make recommendations to the IMO board. The aims of the Technical Panel are listed. The priority issues with significant direct impact on generators are: import and export transmission, including access to the inter-ties, and the Financial Transmission Rights associated with inter-ties, procedures governing new investment in transmission, participation and prudential requirements, and residual risk location, facility aggregation rules, local market power migration, must-run contracts; principles and forms of agreement, penalties for non-compliance with rules, and transitional provisions around market opening. The excluded major market design principles to be resolved by others are covered, as well as how it is decided what issues need attention. The TP does its work by: work planning, policy consultation, rule guidance and direction requests, and proposed rule amendments. Further points are listed concerning: how the TP secures stakeholder input, how the IPPSO stakeholder consultation process works, import and export transmission issues, and accreditation and prudential requirements
IMO and stakeholders looking for improvements: Pricing system under scrutiny
International Nuclear Information System (INIS)
Anon
2002-01-01
Changing the way of how Ontario's electric market clearing price is established has been announced by the Independent Market Operator, in response to excessive price fluctuations following deregulation, and in spite of the considerable concern about how any change to the pricing system might affect investor confidence. To tackle the issue, an internal team was formed, with input to this team through the IMO's Marker Operations Standing Committee. The following pricing issues are considered to be in need of attention: (1) the discrepancy between real-time prices and published pre-dispatch prices; (2) the difference between prices paid for imported power and domestic power during times of shortage; (3) the inclusion of various factors, such as the additional cost of imported power in non-competitive parts of energy bills known as 'uplift charges'; (4) the failure of the market clearing price to reflect the value of power; (5) the use of non-market procedures that have an effect on price; and (6) adjustments to the offer stack designed to reduce volatility during ramp-up periods. The IMO emphasized its keen awareness of how much investor confidence is predicated on the assumption that market conditions alone will determine prices. Accordingly, its actions are guided strictly by the desire to support reliability and are not intended to be seen as intervening in the competitive market

2001-01-01
This report presents an assessment of the date by which the Independent Electricity Market Operator (IMO) will be in a position to open the Ontario electricity market. The report is based on objective results derived from the IMO's own testing and the testing that participants in the electric power market have performed with the IMO. The testing was designed to provide appropriate assurance that the electric power systems and processes would operate according to requirements. The report describes market opening timelines constraints and assumptions. A thorough description of seven conditions that were used to make the readiness assessment for market opening conditions was also included in this report. The conditions included IMO readiness, participant readiness, contingency arrangements, reliable operations, market design, legal framework, and system adequacy. Based on this assessment, the IMO is confident that its systems and capabilities can support a market opening as of March 1, 2002. However, it was noted that market participants would benefit from access to a full production data set to fully complete their testing in mid January 2002. This additional testing would also add confidence in the market. The IMO's advice is that April 1, 2002 would be an appropriate data for market opening. tabs

Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia. © 2015 American Association of Anatomists.

Science education and literacy, along with a focus on the other STEM fields, have been a center of attention on the global scale for decades. The 1950's race to space is often considered the starting point. Through the years, the attention has spread to highlight the United States' scientific literacy rankings on international testing. The ever-expanding global economy and global workplace make the need for literacy in the STEM fields a necessity. Science and academic competitions are worthy of study to determine the overall and specific positive and negative aspects of their incorporation in students' educational experiences. Science Olympiad is a national science and engineering competition that engages thousands of students each year. The purpose of this study was to analyze the perceptions of Science Olympiad participants, in terms of science learning and interest, 21st century skills and abilities, perceived influence on careers, and the overall benefits of being involved in Science Olympiad. The study sought to determine if there were any differences of perception when gender was viewed as a factor. Data was acquired through the Science Olympiad survey database. It consisted of 635 usable surveys, split evenly between males and females. This study employed a mixed methods analysis. The qualitative data allowed the individual perceptions of the respondents to be highlighted and acknowledged, while the quantitative data allowed generalizations to be identified. The qualitative and quantitative data clearly showed that Science Olympiad had an impact on the career choices of participants. The qualitative data showed that participants gained an increased level of learning and interest in science and STEM areas, 21st century skills, and overall positive benefits as a result of being involved. The qualitative data was almost exclusively positive. The quantitative data however, did not capture the significance of each researched category that the qualitative

Full Text Available Abstract Background To evaluate the scientific reasoning in basic science among undergraduate medical students, we established the National Medical Science Olympiad in Iran. In this Olympiad, the drawing of a concept map was used to evaluate a student's knowledge framework; students' ability in hypothesis generation and testing were also evaluated in four different steps. All medical students were invited to participate in this program. Finally, 133 undergraduate medical students with average grades ≥ 16/20 from 45 different medical schools in Iran were selected. The program took the form of four exams: drawing a concept map (Exam I, hypothesis generation (Exam II, choosing variables based on the hypothesis (Exam III, measuring scientific thought (Exam IV. The examinees were asked to complete all examination items in their own time without using textbooks, websites, or personal consultations. Data were presented as mean ± SE of each parameter. The correlation coefficient between students' scores in each exam with the total final score and average grade was calculated using the Spearman test. Results Out of a possible score of 200, the mean ± SE of each exam were as follows: 183.88 ± 5.590 for Exam I; 78.68 ± 9.168 for Exam II; 92.04 ± 2.503 for exam III; 106.13 ± 2.345 for Exam IV. The correlation of each exam score with the total final score was calculated, and there was a significant correlation between them (p The average grade was significantly correlated with the total final score (R = 0.770, (p p R = 0.7708 and the average grade. This means students with higher average grades had better grades in each exam, especially in drawing the concept map. Conclusions We hope that this competition will encourage medical schools to integrate theory and practice, analyze data, and read research articles. Our findings relate to a selected population, and our data may not be applicable to all medical students. Therefore, further studies are

Although some tests for clinical reasoning assessment are now available, the theories of medical expertise have not played a major role in this filed. In this paper, illness script theory was chose as a theoretical framework and contemporary clinical reasoning tests were put together based on this theoretical model. This paper is a qualitative study performed with an action research approach. This style of research is performed in a context where authorities focus on promoting their organizations' performance and is carried out in the form of teamwork called participatory research. Results are presented in four parts as basic concepts, clinical reasoning assessment, test framework, and scoring. we concluded that no single test could thoroughly assess clinical reasoning competency, and therefore a battery of clinical reasoning tests is needed. This battery should cover all three parts of clinical reasoning process: script activation, selection and verification. In addition, not only both analytical and non-analytical reasoning, but also both diagnostic and management reasoning should evenly take into consideration in this battery. This paper explains the process of designing and implementing the battery of clinical reasoning in the Olympiad for medical sciences students through an action research.

Participant priorities for future market development : IMO public consultation report : issue 1.0
International Nuclear Information System (INIS)
2002-01-01
As part of the Independent Electricity Market Operator's (IMO) consultation process on market development priorities, a workshop was held in January 2002 to put forward several market design issues. The 112 delegates included market participants and other stakeholders representing consumers, environmental interest groups and the financial community. The nine main market design issues that need to be addressed over the next several years are: (1) the energy forward market, (2) the capacity reserve market, (3) location marginal pricing, (4) a capability for full assignment of physical bilateral contracts, (5) the export of operating reserve, (6) moving to real time bidding, (7) encouraging dispatchability and demand side responsiveness, (8) transmission expansion, and (9) introducing markets in ancillary services. Sections of the market rules have been deferred to after market opening, and several market development obligations have been placed on the IMO, such as recommendations on the need for location pricing and its implementation timetable. It is expected that significant resources, such as staff, will be required to ensure a smooth opening of the electricity market. It is also noted that US initiatives will affect the IMO's business environment. Prior to the workshop, the participants were asked to rank the nine potential priority issues. The rankings are included in the appendix. Results indicate that location marginal pricing ranks as the first priority, followed by energy forwards market, and then the capacity reserves market. Transmission expansion ranked sixth overall. Harmonisation with the US Northeast was also mentioned in reference to the implementation of day ahead market, location marginal pricing and the implementation of capacity reserve markets. The next step in this IMO consultation process is the development of a work-plan for managing the issues over the medium term. 2 tabs., 1 fig., 4 appendices

The Independent Electricity Market Operator (IMO) is a control area authority that is responsible for the safe and reliable operation of its portion of the bulk electric system in cooperation with neighbouring control areas. This audit by the North American Electric Reliability Council (NERC) reviewed the readiness of Ontario's IMO to meets its responsibilities as a control area operator. NERC recommended specific actions to correct the deficiencies that resulted in the blackout in southeastern Ontario and northeastern United States on August 14, 2003. Initiatives to strengthen compliance with existing standards were also suggested along with longer-term technical initiatives to prevent or mitigate the impacts of cascading blackouts in the future. The audit process included: a self-assessment questionnaire to the control area being audited; a questionnaire to neighbouring control areas; a questionnaire to the reliability coordinator and an on-site audit by a selected audit team. The following issues were reviewed: criteria and compliance, authority, responsibilities in the planning time frame, real time monitoring, system restoration, delegation of reliability coordinator functions, outage coordination, transmission and generation relaying, energy emergency plan, operating policy, line clearances, and nuclear power plant requirements. It was concluded that the IMO has the necessary plans, procedures, processes, tools and trained personnel to respond to emergency events. The audit did not find any major operational problems, but offered a few recommendations for improvement. tabs

The GSJ is the main supporting organization of IYPE Japan, which is an implementation body of IYPE in Japan, serving as its secretariat. During the IYPE triennial activity, the GSJ has been supporting development of Geparks, establishment of "the Geology Day" and the Earth Science Olympiad activities with some academic societies, and has distributed geological maps with IYPE logo. The GSJ also established an outreach network "Geo-networks Tsukuba" as a local legacy of the IYPE, and has managed it with a local government, research organizations, nonprofit corporations and local media to increase geological and environmental literacy of public, especially among young people. The GSJ-AIST has also contributed internationally to IYPE by joining two international projects, OneGeology and the CCOP Book project. Geoparks in Japan are characterized by following features. The Japanese Islands and the surrounding seas are situated in the area of unique geologic features; the place where several tectonic plates meet and collide. This causes earthquakes and volcanic activities, and makes Japan one of most dynamic areas on the earth. The dynamics of the earth bring about not only geological hazards but also a lot of blessings. In August of 2009, three Geoparks, the Toya Caldera and Usu Volcano Geopark, the Itoigawa Geopark and the Unzen Volcanic Area Geopark, were accepted to join the Global Geopark Network from Japan for the first time. Since its launch in 2006, the GSJ has been playing a major role in promoting Geoparks in Japan together with Geological Society of Japan. The GSJ hosts the Japan Geopark Committee (JGC) for quality evaluation, serving as the information center of Geoparks in Japan. The Geology Day of Japan (10th of May) has been set up by the academic societies for geology in Japan and GSJ in 2007. The Geology Day is expected to provide the chances for the public to enjoy field trips and excursions and to understand the importance of geo-diversity. The Day

This groundbreaking work features two essays written by the renowned mathematician Ilan Vardi. The first essay presents a thorough analysis of contrived problems suggested to "undesirable" applicants to the Department of Mathematics of Moscow University. His second essay gives an in-depth discussion of solutions to the Year 2000 International Mathematical Olympiad, with emphasis on the comparison of the olympiad problems to those given at the Moscow University entrance examinations. The second part of the book provides a historical background of a unique phenomenon in mathematics, which flourished in the 1970s-80s in the USSR. Specially designed math problems were used not to test students' ingenuity and creativity but, rather, as "killer problems," to deny access to higher education to "undesirable" applicants. The focus of this part is the 1980 essay, "Intellectual Genocide", written by B Kanevsky and V Senderov. It is being published for the first time. Also featured is a little-known page of the Soviet hi...
An excursion through elementary mathematics, volume iii discrete mathematics and polynomial algebra
Caminha Muniz Neto, Antonio
2018-01-01
This book provides a comprehensive, in-depth overview of elementary mathematics as explored in Mathematical Olympiads around the world. It expands on topics usually encountered in high school and could even be used as preparation for a first-semester undergraduate course. This third and last volume covers Counting, Generating Functions, Graph Theory, Number Theory, Complex Numbers, Polynomials, and much more. As part of a collection, the book differs from other publications in this field by not being a mere selection of questions or a set of tips and tricks that applies to specific problems. It starts from the most basic theoretical principles, without being either too general or too axiomatic. Examples and problems are discussed only if they are helpful as applications of the theory. Propositions are proved in detail and subsequently applied to Olympic problems or to other problems at the Olympic level. The book also explores some of the hardest problems presented at National and International Mathematics Ol...

Full Text Available The preference for cash-less transaction by Nigerians cannot be exaggerated, but despite its patronage, there exist limited access and utilization of the cash-less technologies among farmers in South-East Nigeria. The study analysed the determinants of rural farmers’ preference for cash-less transactions in Imo state, South-East Nigeria. Multi-stage sampling technique was employed in selection of 100 farmers for the study. The determinant of rural farmers’ preference for cash-less transactions in Imo State, was achieved using logit model. The result of the analysis showed that age (5%, gender (10% education levels of the farmers (1%, user friendliness of technologies (5%, transaction charge (5% and security of transactions (5% were found to be the major determinants of farmers preference for cash-less transactions based on their levels of significance. Centred on the findings, the study recommended the strengthening of the use of cash-less transaction by farmers by providing a favourable financial environment through better orientation programs, so as to enable a smooth transition from a cash-based economy to cash-less economy.

This research focused on the processes and physics instruction of 25 schools located in Bangkok and up-country in Thailand in order to explain why many of their students have passed the first round of the National Physics Academic Olympiads consistently. The high schools in Thailand can apply and support their students and develop their potential in physics. The development of physics professional is the cornerstone of a developing country and increase physics quality base on sciences development in the future in Thailand. The duration of collecting all data was from May 2007 to May 2009. The methodology for this research was the qualitative research method. The researchers interviewed managers, teachers and students at each school location or used semi-structured interview forms. The researchers used the Investigator Triangulation approach to check the qualitative data and the Cause and Effect Analysis approach to analyze situation factors. The results showed that in processes were include 1) enhanced the students with the Academic Olympiads to develop the capacities of students; 2) motivated the students with processes such as good instruction in physics and special privilege in continuing studies in university; and 3) tutorial systems and drill and practice systems support students into subsequent rounds. 4) Admiration activities accommodated the students continually and suitably. Most of the teaching styles used in their lectures, in both basic contents and practice, encouraged students to analyze entrance examination papers, little laboratory. While students say that" They just know that a physics laboratory is very important to study physics after they passed Olympic camp."

IMOS (Integrated Marine Observing System) operates a wide range of ocean observing equipment throughout Australia's coastal waters and also the open oceans. This fully integrated, national system, covers physical, chemical and biological ocean sciences forming the basis for robust and informed study of the worlds oceans. Of particular interest in understanding global climate processes is the Southern Ocean (SO), but studying this remote region is difficult and most observations are collected during the short ice-free summer when the region is accessible. Through Winter and Spring it is extremely difficult to collect biophysical ocean information in the Southern Ocean. The importance of good observations from this region, the home of the Antarctic Circumpolar Current (ACC), the largest current system in the world, which connects water masses from the global ocean basins cannot be over emphasised. IMOS through the Australian Animal Tracking and Monitoring System (AATAMS) has made important inroads into collecting otherwise hard to obtain observations from the SO by using CTD bio-loggers to monitor coastal and oceanic movements of marine animals from the Australian mainland as far south as the Antarctic continent. In particular seals equipped with satellite-linked CTD tags have provided unique temporal and spatial coverage of the Southern Ocean. This includes extensive data from the Antarctic continental slope and shelf regions during the winter months, which is outside the conventional areas of Argo autonomous floats and ship-based studies. Over 75,000 temperature and salinity profiles have been collected from 20-140 °E, between the Kerguelen archipelago and Prydz Bay Antarctica. These data offer invaluable new insights into the water masses, oceanographic processes and provides a vital tool for oceanographers seeking to advance our understanding of this key component of the global ocean climate. Here we present an overview of the IMOS database of hydrographic (i

Full Text Available Information on livestock movement, animal food products processing facilities, meat inspection methods, official meat inspection records and distribution and marketing systems for processed products in Imo state, Nigeria needed for policy development interventions in the sector are not fully understood. The primary data generated with the aid of personal interviews, field observations and secondary data obtained from records accumulated by the department of veterinary services Imo state from 2001 to 2004 were used to investigate the environmental and public health issues of animal food products delivery system in state. Majority of trade animals supplied to the state originated from the northern states of the country and were brought in with trucks by road. Only two veterinary control posts served the whole state thus resulting in non-inspection and taxing of a large proportion of trade animals. Official record of trade animals supplied to the state from 2001 to 2004 ranged from 45000 – 144000 for cattle, 23000 – 96000 for goats and 11000 – 72000 for sheep per annum, with supplies increasing steadily across the years. Official slaughter points in the state were principally low-grade quality slaughter premises consisting of a thin concrete slab. Meat handling was very unhygienic with carcasses dressed beside refuse heaps of over 2 years standing. Carcasses were dragged on the ground and transported in taxi boots and open trucks. Meat inspection at these points was not thorough because of stiff resistance of butchers to carcass condemnation. Official meat inspection records for the state from 2001 to 2004 revealed that overall totals of 159,000 cattle, 101,000 goats and 67,000 sheep were slaughtered. This accounted for about 56, 57 and 57% shortfall of cattle, goat and sheep respectively supplied to the state and represents the volume of un-inspected animals during the study period. Fascioliasis and tuberculosis were the most common

Full Text Available In offshore industry activities, the suitable onboard provision of assets location and geospatial marine information during operations is essential. Currently, most companies use its own data structures, resulting in incompatibility between processes. In order to promote the data exchange, oil and gas industry associations have pursued initiatives to standardize spatial information. In turn, the IMO - International Maritime Organization - started the implementation of e-Navigation policy, which is the standardization of technologies and protocols applied to maritime information and navigation. This paper shows relationship and integration points between maritime activities of oil and gas industry and e-Navigation technologies and processes, highlighting geospatial information. This paper also preludes out an initiative for a suitable product specification for the offshore oil and gas industry, compliant with e-Navigation and IHO S-100 international standards.

Limited knowledge and practice of contraception is a global public health problem. Unintended pregnancies are the primary cause of induced abortion. When safe abortions are not available, as in Nigeria with restricted abortion laws, abortion can contribute significantly to maternal mortality and morbidity. Adequate information on the awareness and the use of emergency contraception is necessary for planning interventions in groups vulnerable to unwanted pregnancy. The aim of the following study is to access the awareness, perception and practice of emergency contraception among female undergraduates in Imo State University, South Eastern Nigeria. A questionnaire based cross-sectional survey using female undergraduates selected randomly from Imo State University, Owerri. A total of 700 students participated in the study. Awareness of emergency contraception was very high (85.1%) (596/700). The awareness was significantly higher amongst students in health related faculties than in the non-health related faculties (P = 0.01). The main sources of information were through friends (43.1%) (317/700) and lectures (22.1%) (192/700). High dose progestogen (postinor-2) was the most commonly known type of emergency contraception (70.8%) (422/596). Only 58.1% (346/596) of those who were aware of emergency contraception approved of their use. The major reasons given by the 41.9% (250/596) who disapproved of their use were religious reasons (50.4%) (126/250) and that they were harmful to health (49.2%) (123/250). Two-third (67%) (46 9/700) of the students were sexually active and only 39.9% (187/469) of them used emergency contraception. High dose progestogen (postinor-2) was again the most commonly used method (70.8%) (422/596). The most common situation in which emergency contraception was used was following unprotected sexual intercourse (45.5%) (85/144). Only 34.6% (206/596) of those who were aware of emergency contraception identified correctly the appropriate time interval

Every year, hundreds of thousands of students and teachers from all over the country take part in the Brazilian Olympiad of Astronomy and Astronautics (OBA). This has the aim of both spreading astronomy and astronautics-related concepts and training teachers about these topics. After being marked some of the exams are sent by participant schools to the Organizing Committee to select candidates for the international competition. The OBA exam archive thereby offers an unique opportunity to evaluate the teaching of astronomy in Brazil in relation to school level and content, as well as over time. Understanding the misconceptions unraveled by the exams is of utmost importance to planning successful outreach activities. In this talk I will present how the analysis of the 2013 OBA event helped the Museum of Astronomy and Related Sciences to develop an astronomy education kit aimed at teachers and how this cooperation between an academic institution and schools is helping educators in their pedagogical practice to teach astronomy in the classroom.

All nuclear electric power reactors in operation and under construction by the end of 1988 are tabulated. Unclassified published statistics show that in 1988, on a world basis, there were 376 active nuclear powered submarines and surface craft, while 47 were under construction or in the process of conversion. Information on types, number of units, and nationality of these nuclear powered navy vessels is given. Parallel to this development, the Soviet Union has successfully built and put into operation a fleet of nuclear powered icebreakers, starting with the Lenin, commissioned in 1959. The first nuclear powered merchant ship, the United States' Savannah, was launched on 21 July 1959, and put into service on 1 May 1962. The Federal Republic of Germany put their nuclear propelled merchant ship Otto Hahn into operation in October 1968, and in November the same year the keel of the first Japanese nuclear ship, the Mutsu, was laid. The International Maritime Organisation (IMO) has, throughout its thirty year existence, made recommendations and developed a Nuclear Ship Safety Code to cover the safety requirements of nuclear ships, and has promoted the peaceful uses of nuclear energy. With the depletion of natural resources and environmental pollution such as the emission of gases causing the greenhouse effect, the correct and safe application of nuclear energy for peaceful purposes, including merchant ships, is likely to be the most efficient and hygienic source of energy in the next century.

The electricity market in Ontario was opened on May 1, 2002. This document provides the executive summary for the first monitoring report prepared by the Market Surveillance Panel covering the period May to August 2002. In the introductory chapter of the main report, explanations are provided on why competition, when effective, benefits consumers, as well as touching on the conditions for the design of an effective competitive electricity market with special emphasis on the electricity market in Ontario and its operations. For the period under review, the report presents a description and analysis of the activities and operations of the Independent Electricity Market Operator (IMO)-administered markets (focus on energy markets). Rising costs for hydroelectric power and very high temperatures combined in July and August resulting in record levels of demand. It became apparent that the province relies on imports to satisfy demand. The figures reveal that reliability in July and August depended on imports 21 per cent of the time. A serious shortage of generating capacity exists in Ontario and steps to rectify the situation should be initiated to ensure reliability of electricity supply for next summer. Prospective entrants in the electricity market in Ontario may not be receiving clear, credible and consistent signals. Effective use of existing or potential transmission capacity may not always be made by the system. The lowering of consumption by consumers is difficult since consumers are not properly equipped, resulting in their lack of power to discipline price increases from suppliers. The future evolution of the market must be planned and measures implemented to enhance the effectiveness of competition. The incentives effects for some aspects of the market design do not completely satisfy the Panel

Sustained observations allow for the tracking of change in oceanography and ecosystems, however, these are rare, particularly for the Southern Hemisphere. To address this in part, the Australian Integrated Marine Observing System (IMOS) implemented a network of nine National Reference Stations (NRS). The network builds on one long-term location, where monthly water sampling has been sustained since the 1940s and two others that commenced in the 1950s. In-situ continuously moored sensors and an enhanced monthly water sampling regime now collect more than 50 data streams. Building on sampling for temperature, salinity and nutrients, the network now observes dissolved oxygen, carbon, turbidity, currents, chlorophyll a and both phytoplankton and zooplankton. Additional parameters for studies of ocean acidification and bio-optics are collected at a sub-set of sites and all data is made freely and publically available. Our preliminary results demonstrate increased utility to observe extreme events, such as marine heat waves and coastal flooding; rare events, such as plankton blooms; and have, for the first time, allowed for consistent continental scale sampling and analysis of coastal zooplankton and phytoplankton communities. Independent water sampling allows for cross validation of the deployed sensors for quality control of data that now continuously tracks daily, seasonal and annual variation. The NRS will provide multi-decadal time series, against which more spatially replicated short-term studies can be referenced, models and remote sensing products validated, and improvements made to our understanding of how large-scale, long-term change and variability in the global ocean are affecting Australia's coastal seas and ecosystems. The NRS network provides an example of how a continental scaled observing systems can be developed to collect observations that integrate across physics, chemistry and biology. PMID:25517905

Full Text Available This study was on the impact of agricultural intensification on poverty alleviation among rural farm households in Imo State Nigeria. Multi-stage random sampling and purposive sampling technique was used in choosing the samples used for the study. Data collections were by the use of structured questionnaire and interview schedules and data analysis involved the computation per capital household food expenditure and mean per capita household expenditure so as to draw the poverty line and hence derive the poverty status of the respondents, regression analysis as well as computation of the Chow’s statistic. The results of data analysis revealed that poverty is more pronounced with the farm households that are not practicing agricultural intensification. The significant factors influencing the poverty level of the farmers practicing agricultural intensification were sex of household head, years of formal education, assets endowment, and income; while for the farmers not practicing intensification, household size, years of formal education, assets endowment, and income were the significant factors influencing their poverty level. For the two households, age, years of formal education, assets endowment, and income were the significant factors influencing their poverty level. Education, income and the dummy variable indicating intensification status were the significant factors influencing their poverty level for the entire household with a dummy introduced. The Chow’s test revealed that agricultual intensification has a positive and significant impact on poverty reduction. Therefore, creation of awareness and persuading rural farming households to practice more of intensified agriculture would lead increase in productivity and income with a multiplier effect on poverty reduction.

Full Text Available Three materials SUS304, 9% Ni steel and Al 5083-O alloy, which are considered possible candidate for International Maritime Organization (IMO type B Cargo Containment System, were studied. Monotonic tensile, fatigue, fatigue crack growth rate and Crack Tip Opening Displacement tests were carried out at room, intermediate low (-100 °C and cryogenic (-163 °C temperatures. The initial yield and tensile strengths of all materials tended to increase with decreasing temperature, whereas the change in elastic modulus was not as remarkable. The largest and smallest improvement ratio of the initial yield strengths due to a temperature reduction were observed in the SUS304 and Al 5083-O alloy, respectively. The fatigue strengths of the three materials increased with decreasing temperature. The largest increase in fatigue strength was observed in the Al 5083-O alloy, whereas the 9% Ni steel sample showed the smallest increase. In the fatigue crack growth rate test, SUS304 and Al 5083-O alloy showed a decrease in the crack propagation rate, due to decrease in temperature, but no visible improvement in da/dN was observed in the case of 9% Ni steel. In the Crack Tip Opening Displacement (CTOD test, CTOD values were converted to critical crack length for the comparison with different thickness specimens. The critical crack length tended to decrease in the case of SUS304 and increase for the Al 5083-O alloy with decreasing temperature. In case of 9% Ni steel, change of critical crack length was not observed due to temperature decrease. In addition, the changing material properties according to the temperature of the LNG tank were analyzed according to the international code for the construction and equipment of ships carrying liquefied gases in bulk (IGC code and the rules of classifications.

Objectives: The present study sought to investigate the role of palm oil, in conjunction with the duration of fermentation, on cyanide and aflatoxin (AFT) loads of processed cassava tubers (Garri). Materials and Methods: Matured cassava (Manihot esculenta Crantz) tubers were harvested from three different locations (Akunna, Mkporo-Oji and Durungwu) in Njaba Local Government Area, Imo State, Nigeria. The cassava tubers were processed into Garri according to standard schemes with required modifications and measured for cyanide content using titrimetric methods. Samples of Garri for determination of AFT levels were stored for 30 days before the commencement of spectrophotometric analysis. Results: Cyanide content of peeled cassava tubers was within the range of 4.07 ± 0.16-5.20 ± 0.19 mg hydrocyanic acid (HCN) equivalent/100 g wet weight, whereas the various processed cassava tubers was within the range of 1.44 ± 0.34-3.95 ± 0.23 mg HCN equivalents/100 g. For the 48 h fermentation scheme, Garri treated with palm oil exhibited marginal reduction in cyanide contents by 0.96%, 3.52% and 3.69%, whereas 4 h fermentation scheme is in concurrence with palm oil treatment caused 4.42%, 7.47% and 5.15% elimination of cyanide contents compared with corresponding untreated Garri samples (P > 0.05). Levels of AFT of the various Garri samples ranged between 0.26 ± 0.07 and 0.55 ± 0.04 ppb/100 g. There was no significant difference (P > 0.05) in AFT levels among the various samples in relation to their corresponding sources. Conclusion: The present study showed that the 48 h fermentation scheme for Garri production caused significant (P < 0.05) reduction, but did not obliterate the cyanide content of cassava tubers. Conversely, the 48 h fermentation scheme promoted the elevation of AFT levels, but was relatively reduced in Garri samples treated with palm oil. PMID:24403736

More stringent emission limits for large engines are dominating research and development activities of engine and component manufacturers during the next years. This is especially the case with respect to the introduction of the IMO-TIER 3 limits in the emission control areas in 2016. Then a reduction of nitrogen oxides emissions of roughly 80% compared to today is required. In particular in combination with new regulations on the fuel sulfur content or on the sulfur oxide emissions respectively totally new technological approaches have to be applied to marine diesel engines and their periphery. Technical solutions based on exhaust gas treatment like SCR-catalysts or sulfur scrubbers as well as exhaust gas recirculation concepts are discussed in this paper. Depending on the specific method there is a need to handle different operating materials such as heavy fuel oil, distillate fuels, urea solution, caustic soda lye or lime. Furthermore specific challenges for the development and application of advanced fuel injection systems and injection strategies are mentioned. It is to be assumed that several emission reduction concepts will be available in 2016. Depending on the skip type and the characteristic deployment an optimum concept has to be selected. Because of the complexity of the different technologies strong repercussions are implied on the ship layout and marine engine operation. (orig.)

Full Text Available The major aim of this study was to investigate the effect of insecurity of school environment on the academic performance of secondary school students in Imo state, Nigeria. A total of 1000 made up of 500 each of male and female students responded to a self-structured validated questionnaire designed for the study. Two research questions and two hypotheses were formulated to guide the study. Means and standard deviations were calculated to answer the research questions and independent samples t-tests were used for testing the hypotheses. Major findings revealed that insecurity of school environment significantly affects the academic performance of secondary school students while students’ gangsterism, smoking of Indian hemp, abusing other hard drugs, cult and related violent activities were some of the factors that constituted insecurity of the school environment which eventually cause boys to leave school and join trading while leading girls to drop out and settle for marriage. Based on the findings, it was recommended that owners of schools and other stakeholders in education should take bold steps to fence and protect school environments from intruders to ensure safety of the students.

Full Text Available Competition is necessary for enhanced customer welfare and efficiency. This study focused on marketing efficiency of packaged water in Imo state Nigeria. It specifically examined the socio-economic profile of the respondents; levels of marketing efficiency of packaged water and its determinants. The study employed purposive and multistage sampling technique in the selection of location and respondents respectively from whom information were elicited. Analytically, descriptive statistics, schematic diagram and OLS multiple regression models were used. Results showed that the respondents were predominantly married male adults, with average household size of 7 persons. They were fairly educated and experienced in the business. The study further revealed that age, education, household size and income were the major determinants of marketing efficiency of packaged water marketing in the area. The result also showed that net income, marketing cost, and marketing margin were higher in urban area, which implies that marketer in semi-urban areas were operating below optimum efficiency levels. This study therefore suggested the need to incorporate integrated logistics management and marketing strategies as a measure to reduce unnecessary marketing costs; capacity enhancement programmes for marketers and improvement in infrastructural development as a means of addressing marketing efficiency and customer welfare.

Morbidity due to dracunculiasis (guinea worm disease) and diarrhoea in persons of all ages, and nutritional status of young children, were used as health impact indicators in the evaluation of the Imo State Drinking Water Supply and Sanitation Project in south-eastern Nigeria. Data were collected using repeated cross-sectional surveys and longitudinal follow-up. The study area was found to have a low level of endemicity of dracunculiasis. While no impact could be demonstrated on overall period or point prevalence rates in the cross-sectional surveys, a prospective longitudinal survey showed a significant reduction in the percentage of person-fortnights positive for dracunculiasis in areas served by the project, while the control areas showed no such change. In the cross-sectional surveys it was found that, in the project villages, those persons drinking only borehole water had significantly lower period prevalence rates one year later than others. Moreover, those living further from the nearest borehole had higher rates of dracunculiasis. An impact of the project on diarrhoea morbidity was found only in limited sub-groups of the population. A greater association with water availability rather than quality was suggested for rates in young children. The prevalence of wasting (less than 80% weight-for-height) among children aged less than 3 years decreased significantly over time in all 3 intervention villages; there was no such decline in the control villages.

Full Text Available This study on marketing of breadfruits (Treculia africana and returns was done in Ahiazu Mbaise local Government area of Imo State, Nigeria. The specific objectives of the study were to describe socio-economic characteristics of respondents (sellers and buyers of African breadfruit; identify value-chain activities available in processing and its storage in compliance with consumers’ order and preferences; determine factors influencing decision to supply African breadfruit; and constraints with its post-harvest management in the study area. Three-stage random sampling technique was used in selecting locations and respondents through which eighty (80 farm households who gather/harvest, process and sell breadfruits were selected and interviewed with structured questionnaire. Data collected were analyzed using descriptive statistics, and probit regression model. Result revealed that 65.80% of the respondents were females and 81.20% of them were married with mean household size of 9 members. Their literacy level was high as 97.6% of them had at least primary education. Predominant marketing activities were fruit gathering/harvesting, processing, storage and packaging, transportation, and sales. Socio-economic factors of gender, household size, income, level of education, years of farming experience and labour significantly influenced supply of breadfruits to consumers with challenges of seasonal scarcity, and tedious methods of processing deterring the enterprise in the area. We recommended provision of credit support to enable fruit gatherers purchase and use shelling machines and good storage facilities to smooth any fluctuations in supplies during off-seasons and help fight overdependence of households on roots and tubers.

Answering to the double-faced influence of string theory on mathematical practice and rigour, the mathematical physicists Arthur Jaffe and Frank Quinn have contemplated the idea that there exists a `theoretical' mathematics (alongside `theoretical' physics) whose basic structures and results still require independent corroboration by mathematical proof. In this paper, I shall take the Jaffe-Quinn debate mainly as a problem of mathematical ontology and analyse it against the backdrop of two philosophical views that are appreciative towards informal mathematical development and conjectural results: Lakatos's methodology of proofs and refutations and John von Neumann's opportunistic reading of Hilbert's axiomatic method. The comparison of both approaches shows that mitigating Lakatos's falsificationism makes his insights about mathematical quasi-ontology more relevant to 20th century mathematics in which new structures are introduced by axiomatisation and not necessarily motivated by informal ancestors. The final section discusses the consequences of string theorists' claim to finality for the theory's mathematical make-up. I argue that ontological reductionism as advocated by particle physicists and the quest for mathematically deeper axioms do not necessarily lead to identical results.

Mathematical psychology is a sub-field of psychology that started in the 1950s and has continued to grow as an important contributor to formal psychological theory, especially in the cognitive areas of psychology such as learning, memory, classification, choice response time, decision making, attention, and problem solving. In addition, there are several scientific sub-areas that were originated by mathematical psychologists such as the foundations of measurement, stochastic memory models, and psychologically motivated reformulations of expected utility theory. Mathematical psychology does not include all uses of mathematics and statistics in psychology, and indeed there is a long history of such uses especially in the areas of perception and psychometrics. What is most unique about mathematical psychology is its approach to theory construction. While accepting the behaviorist dictum that the data in psychology must be observable and replicable, mathematical models are specified in terms of unobservable formal constructs that can predict detailed aspects of data across multiple experimental and natural settings. By now almost all the substantive areas of cognitive and experimental psychology have formal mathematical models and theories, and many of these are due to researchers that identify with mathematical psychology.

The book is a textbook (with many exercises) giving an in-depth account of the practical use of mathematical modelling in the biomedical sciences. The mathematical level required is generally not high and the emphasis is on what is required to solve the real biological problem. The subject matter is drawn, e.g. from population biology, reaction kinetics, biological oscillators and switches, Belousov-Zhabotinskii reaction, reaction-diffusion theory, biological wave phenomena, central pattern generators, neural models, spread of epidemics, mechanochemical theory of biological pattern formation and importance in evolution. Most of the models are based on real biological problems and the predictions and explanations offered as a direct result of mathematical analysis of the models are important aspects of the book. The aim is to provide a thorough training in practical mathematical biology and to show how exciting and novel mathematical challenges arise from a genuine interdisciplinary involvement with the biosci...

Although today's mathematical research community takes its international character very much for granted, this "global nature" is relatively recent, having evolved over a period of roughly 150 years-from the beginning of the nineteenth century to the middle of the twentieth century. During this time, the practice of mathematics changed from being centered on a collection of disparate national communities to being characterized by an international group of scholars for whom the goal of mathematical research and cooperation transcended national boundaries. Yet, the development of an international community was far from smooth and involved obstacles such as war, political upheaval, and national rivalries. Until now, this evolution has been largely overlooked by historians and mathematicians alike. This book addresses the issue by bringing together essays by twenty experts in the history of mathematics who have investigated the genesis of today's international mathematical community. This includes not only develo...

Full Text Available It is very difficult to motivate students when it comes to a school subject like Mathematics. Teachers spend a lot of time trying to find something that will arouse interest in students. It is particularly difficult to find materials that are motivating enough for students that they eagerly wait for the next lesson. One of the solutions may be found in Vedic Mathematics. Traditional methods of teaching Mathematics create fear of this otherwise interesting subject in the majority of students. Fear increases failure. Often the traditional, conventional mathematical methods consist of very long lessons which are difficult to understand. Vedic Mathematics is an ancient system that is very flexible and encourages the development of intuition and innovation. It is a mental calculating tool that does not require a calculator because the calculator is embedded in each of us. Starting from the above problems of fear and failure in Mathematics, the goal of this paper is to do research with the control and the experimental group and to compare the test results. Two tests should be done for each of the groups. The control group would do the tests in the conventional way. The experimental group would do the first test in a conventional manner and then be subjected to different treatment, that is to say, be taught on the basis of Vedic Mathematics. After that, the second group would do the second test according to the principles of Vedic Mathematics. Expectations are that after short lectures on Vedic mathematics results of the experimental group would improve and that students will show greater interest in Mathematics.

Mathematical Physics is an introduction to such basic mathematical structures as groups, vector spaces, topological spaces, measure spaces, and Hilbert space. Geroch uses category theory to emphasize both the interrelationships among different structures and the unity of mathematics. Perhaps the most valuable feature of the book is the illuminating intuitive discussion of the ""whys"" of proofs and of axioms and definitions. This book, based on Geroch's University of Chicago course, will be especially helpful to those working in theoretical physics, including such areas as relativity, particle

This book provides a thorough introduction to the challenge of applying mathematics in real-world scenarios. Modelling tasks rarely involve well-defined categories, and they often require multidisciplinary input from mathematics, physics, computer sciences, or engineering. In keeping with this spirit of modelling, the book includes a wealth of cross-references between the chapters and frequently points to the real-world context. The book combines classical approaches to modelling with novel areas such as soft computing methods, inverse problems, and model uncertainty. Attention is also paid to the interaction between models, data and the use of mathematical software. The reader will find a broad selection of theoretical tools for practicing industrial mathematics, including the analysis of continuum models, probabilistic and discrete phenomena, and asymptotic and sensitivity analysis.

Algorithms play an increasingly important role in nearly all fields of mathematics. This book allows readers to develop basic mathematical abilities, in particular those concerning the design and analysis of algorithms as well as their implementation. It presents not only fundamental algorithms like the sieve of Eratosthenes, the Euclidean algorithm, sorting algorithms, algorithms on graphs, and Gaussian elimination, but also discusses elementary data structures, basic graph theory, and numerical questions. In addition, it provides an introduction to programming and demonstrates in detail how to implement algorithms in C++. This textbook is suitable for students who are new to the subject and covers a basic mathematical lecture course, complementing traditional courses on analysis and linear algebra. Both authors have given this "Algorithmic Mathematics" course at the University of Bonn several times in recent years.

There has been a long history of interaction between mathematics and physiology. This book looks in detail at a wide selection of mathematical models in physiology, showing how physiological problems can be formulated and studied mathematically, and how such models give rise to interesting and challenging mathematical questions. With its coverage of many recent models it gives an overview of the field, while many older models are also discussed, to put the modern work in context. In this second edition the coverage of basic principles has been expanded to include such topics as stochastic differential equations, Markov models and Gibbs free energy, and the selection of models has also been expanded to include some of the basic models of fluid transport, respiration/perfusion, blood diseases, molecular motors, smooth muscle, neuroendrocine cells, the baroreceptor loop, turboglomerular oscillations, blood clotting and the retina. Owing to this extensive coverage, the second edition is published in two volumes. ...

Mathematical models are the decisive tool to explain and predict phenomena in the natural and engineering sciences. With this book readers will learn to derive mathematical models which help to understand real world phenomena. At the same time a wealth of important examples for the abstract concepts treated in the curriculum of mathematics degrees are given. An essential feature of this book is that mathematical structures are used as an ordering principle and not the fields of application. Methods from linear algebra, analysis and the theory of ordinary and partial differential equations are thoroughly introduced and applied in the modeling process. Examples of applications in the fields electrical networks, chemical reaction dynamics, population dynamics, fluid dynamics, elasticity theory and crystal growth are treated comprehensively.

Progress for the past decade or so has been extraordinary. The solution of Fermat's Last Theorem [11] and of the Poincare Conjecture [1] have resolved two of the most outstanding challenges to mathematics. For both cases, deep and advanced theories and whole subfields of mathematics came into play and were developed further as part of the solutions. And still the future is wide open. Six of the original seven problems from the Clay Foundation challenge remain open, the 23 DARPA challenge problems are open. Entire new branches of mathematics have been developed, including financial mathematics and the connection between geometry and string theory, proposed to solve the problems of quantized gravity. New solutions of the Einstein equations, inspired by shock wave theory, suggest a cosmology model which fits accelerating expansion of the universe possibly eliminating assumptions of 'dark matter'. Intellectual challenges and opportunities for mathematics are greater than ever. The role of mathematics in society continues to grow; with this growth comes new opportunities and some growing pains; each will be analyzed here. We see a broadening of the intellectual and professional opportunities and responsibilities for mathematicians. These trends are also occuring across all of science. The response can be at the level of the professional societies, which can work to deepen their interactions, not only within the mathematical sciences, but also with other scientific societies. At a deeper level, the choices to be made will come from individual mathematicians. Here, of course, the individual choices will be varied, and we argue for respect and support for this diversity of responses. In such a manner, we hope to preserve the best of the present while welcoming the best of the new.

The main intention of this book is to describe and develop the conceptual, structural and abstract thinking of mathematics. Specific mathematical structures are used to illustrate the conceptual approach; providing a deeper insight into mutual relationships and abstract common features. These ideas are carefully motivated, explained and illustrated by examples so that many of the more technical proofs can be omitted. The book can therefore be used: · simply as an overview of the panorama of mathematical structures and the relations between them, to be supplemented by more detailed texts whenever you want to acquire a working knowledge of some structure · by itself as a first introduction to abstract mathematics · together with existing textbooks, to put their results into a more general perspective · to gain a new and hopefully deeper perspective after having studied such textbooks Mathematical Concepts has a broader scope and is less detaile...

This book presents concise descriptions and analysis of the classical and modern models used in mathematical biophysics. The authors ask the question "what new information can be provided by the models that cannot be obtained directly from experimental data?" Actively developing fields such as regulatory mechanisms in cells and subcellular systems and electron transport and energy transport in membranes are addressed together with more classical topics such as metabolic processes, nerve conduction and heart activity, chemical kinetics, population dynamics, and photosynthesis. The main approach is to describe biological processes using different mathematical approaches necessary to reveal characteristic features and properties of simulated systems. With the emergence of powerful mathematics software packages such as MAPLE, Mathematica, Mathcad, and MatLab, these methodologies are now accessible to a wide audience. Provides succinct but authoritative coverage of a broad array of biophysical topics and models Wr...

This book contains a collection of exercises (called “tapas”) at undergraduate level, mainly from the fields of real analysis, calculus, matrices, convexity, and optimization. Most of the problems presented here are non-standard and some require broad knowledge of different mathematical subjects in order to be solved. The author provides some hints and (partial) answers and also puts these carefully chosen exercises into context, presents information on their origins, and comments on possible extensions. With stars marking the levels of difficulty, these tapas show or prove something interesting, challenge the reader to solve and learn, and may have surprising results. This first volume of Mathematical Tapas will appeal to mathematicians, motivated undergraduate students from science-based areas, and those generally interested in mathematics.

This book teaches the art of writing mathematics, an essential -and difficult- skill for any mathematics student. The book begins with an informal introduction on basic writing principles and a review of the essential dictionary for mathematics. Writing techniques are developed gradually, from the small to the large: words, phrases, sentences, paragraphs, to end with short compositions. These may represent the introduction of a concept, the abstract of a presentation or the proof of a theorem. Along the way the student will learn how to establish a coherent notation, mix words and symbols effectively, write neat formulae, and structure a definition. Some elements of logic and all common methods of proofs are featured, including various versions of induction and existence proofs. The book concludes with advice on specific aspects of thesis writing (choosing of a title, composing an abstract, compiling a bibliography) illustrated by large number of real-life examples. Many exercises are included; over 150...

With a unique approach and presenting an array of new and intriguing topics, Mathematical Quantization offers a survey of operator algebras and related structures from the point of view that these objects are quantizations of classical mathematical structures. This approach makes possible, with minimal mathematical detail, a unified treatment of a variety of topics.Detailed here for the first time, the fundamental idea of mathematical quantization is that sets are replaced by Hilbert spaces. Building on this idea, and most importantly on the fact that scalar-valued functions on a set correspond to operators on a Hilbert space, one can determine quantum analogs of a variety of classical structures. In particular, because topologies and measure classes on a set can be treated in terms of scalar-valued functions, we can transfer these constructions to the quantum realm, giving rise to C*- and von Neumann algebras.In the first half of the book, the author quickly builds the operator algebra setting. He uses this ...

Full Text Available Information on the resistance profiles of normal intestinal flora of extensively reared chickens that hardly receive antibiotics in the developing countries can serve as important means of understanding the human/animal pathogens drug resistance interactions in the zone. Three hundred and fifty E. coli isolates, comprising 133 from urban and 217 from rural sites in Imo state, Nigeria, were screened for anti-microbial resistance profile against 10 antibiotics using the disc diffusion method. Overall percentage anti-microbial resistance of the isolates against cotrimoxazole, ampicillin, nalidixic acid, chloramphenicol and nitrofurantoin (72–92% were very high. The organisms were highly sensitive to other antibiotics, especially gentamicin and ciprofloxacin. The 59.5% overall mean percentage resistance recorded at the urban area was significantly higher than the 46.8% recorded at the rural area (p<0.05. With the exception of the figures for cotrimoxazole and ampicillin, resistance values obtained against the other antibiotics at the urban sites were statistically higher than those obtained at the rural sites (p<0.05. Zero resistance was recorded against the fluoroquinolones, norfloxacin and ciprofloxacin at all the rural sites except at Enyiogwugwu where a 28.6% resistance was obtained against norfloxacin. Since free-range chickens rarely receive antibiotic medication, it is concluded that the highly resistant E. coli organisms isolated from them may be reflecting consequences of human drug use in the study areas.

This monograph is intended to present the most important methods of proof theory in intuitionistic logic, assuming the reader to have mastered an introductory course in mathematical logic. The book starts with purely syntactical methods based on Gentzen's cut-elimination theorem, followed by intuitionistic arithmetic where Kleene's realizability method plays a central role. The author then studies algebraic models and completeness theorems for them. After giving a survey on the principles of intuitionistic analysis, the last part of the book presents the cut-elimination theorem in intuitionistic simple theory of types with an extensionality rule.

Full Text Available Background: Oil exploration operations decreased the cultivable lands of rural people in the study area, leading to the establishment of the Green River Project (GRP. This study assessed the effectiveness and constraints of private sector extension services of GRP in Imo and Rivers States, Nigeria. Objectives: To analyse the roles and effectiveness of, as well as constraints to, the GRP in the area. Method: A multistage sampling technique was used to select 120 respondents. Descriptive statistics, factor analysis, chi square and t-test were used to analyse the data. Results: Roles of GRP in farming technologies dissemination included training of farmers on fish pond construction technique and maintenance of good pH levels. There was significant improvement in standard of living (X2 = 15.7; p ≤ 0.05 and size of production (t = 6.398; p ≤ 0.05 of the respondents after participation. In terms of the effectiveness of private sector deliveries on public policies, the programme had effect on beneficiaries’ access to credit, education of wards and poverty reduction. But it is worthy to note that the observed changes may not have been solely caused by the GRP, given that there could be many other factors affecting fish farming, either positively or negatively. Serious implementation constraints to effective performance of GRP included organisational, input and sustainability constraints. Conclusion: It was recommended that there should be timely provision of sufficient inputs to farmers and measures to improve organisation of private sector extension services in the area in order to enhance development.

The Market Surveillance Panel is an independent body appointed by Ontario's Independent Electricity Market Operator. The Panel's mandate is to monitor the behaviour in the marketplace, examine the behaviour of specific market participants, investigate design rules and operating procedures, and provide periodic reports on the state of the marketplace. This third period report covers the first 18 months of the Ontario electricity marketplace from May 1, 2002 to October 31, 2003. The report includes an overall assessment of the evolution of the market with emphasis on what has worked well and needs improvement. It also includes a high level overview of market outcomes and basic data for comparison. Market performance that was outside of expected norms was explained. A status report is also presented on the IMO initiatives that have been in place since market opening to improve market performance. The Panel concluded that the electricity market is evolving in a manner that promotes market efficiency and system reliability. Demand for electricity in Ontario continues to increase. More Ontario-based generation was available in 2003 because of the addition of new and restored generation in the province and fewer significant outages. The Panel's reaction to the August 14, 2003 blackout was presented. The Interim report of the Canada-U.S. Power System Outage Task Force has indicated that the blackout was not caused by Ontario electricity markets. No correlation was found between the blackout and the restructuring of the electricity utility industry. Planned or forced outages can have a significant impact on price. Average prices for the off-peak period show an upward trend up to February 2003. 49 refs., 37 tabs., 15 figs

Shrimp species (Macrobrachium felicinum) collected from estuarine mangrove area of the Imo River is an important route of exposure to polycyclic aromatic hydrocarbons (PAHs). The estuarine associated sediment (EAS) composited sample showed higher TPAH, ΣAlkyl, ΣPAH carc and ΣPAH EPA concentrations (550.84, 172.36, 413.17 and 482.11 ng/g dry weight-dw) than their mean concentrations in shrimp samples (509.39 ± 354.21, 31.38 ± 18.49, 52.10 ± 1.35 and 460.06 ± 330.76 ng/g wet weight-ww), respectively. Among the individual PAHs congeners, phenanthrene was the dominant species detected in the EAS accounting for 21.02 % of the total PAH load and the decreasing order of 3- > 2- > 5- > 4- > 6-ring contamination was found. A different pattern predominated by naphthalene was observed for the shrimp species, suggesting that the organisms have different selectivity for a range of PAHs congeners. These variations may be attributed to different degree of bioavailability of these compounds, characteristic sandy lithology of the EAS and the protective capacity of soot particles associated with liquid fossil fuel combustion masking the uptake of high molecular weight PAHs by the organisms. Cancer risk associated with consumption of shrimps in the region was assessed using estimated daily intake (EDI) and compared with standards. The EDI values for naphthalene, benzo(a)pyrene and ∑PAH carc were lower than the USEPA benchmarks and EFSA levels of concern values for adult and children population, suggesting low probability of developing cancer.

The results of the survey are provided in two volumes: the first one containing the description of the search and search results with the list of generated publication titles, and the second volume containing the abstracts of those publications deemed relevant for the purposes of the literature survey. Literature published between 1980 and mid-1999 was reviewed by two independent consultants who generated publication titles by performing searches of appropriate databases, and selected the abstracts of relevant publications for inclusion in this survey. The IAEA operates INIS, the world's leading computerised bibliographical information system on the peaceful uses of nuclear energy. The acronym INIS stands for International Nuclear Information System. INIS Members are responsible for determining the relevant nuclear literature produced within their borders or organizational confines, and then preparing the associated input in accordance with INIS rules. INIS records are included in other major databases such as the Energy, Science and Technology database of the DIALOG service. Because it is the INIS Members, rather than the IAEA Secretariat, who are responsible for its contents, it was considered appropriate that INIS be the primary source of information for this literature review.

More than half of our students worry whether they will have difficulties in mathematics class or whether they will earn poor marks. Aims of this study therefore are: examining relationship between math anxiety and achievement at mathematics literacy scale; establishing possible predictors of math anxiety and identification of students' groups in relations to their relationship towards mathematics as a subject. Mathematics anxiety is statistically negatively correlated with school achievement and achievement at mathematics literacy scale. Socio-demographic factors, motivational and cognitive aspects related to learning mathematics, perception of school and classroom climate explain 40% variance of mathematics anxiety. Based on students' relationship towards mathematics they cam be divided into three groups; while dimensions that apart them are uninterested-interested in mathematics and presence-absence of anxiety. The group displaying anxiety scores lowest among the three. Applying qualitative analysis students' and teachers' attitudes on specific issues related to teaching and learning mathematics was examined.

Full Text Available Introduction: Studying mental and physical health and their determinants is an important issue, especially among future health providers.Methods: This is a sectional-analytical study whose target population was students who had participated in the 4th National Olympiad of Medical Sciences Universities in Tabriz, Iran, held in February 4-7 2013.Web-based designed questionnaires were sent to all 328 participating students’ emails containing our questionnaires that were designed as web-based through Google Drive was sent to all available email addresses of our target population. Questionnaires consisted of student life stress inventory (SLSI, SF-36 (Short Form Health Survey, and College Self-Efficacy Inventory (CSEI, which were translated to Persian and revalidated. The data were analyzed using SPSS ver.19 software.Results: 59 students completely filled the questionnaires and enrolled in the study. In the area of student life stress inventory, the total score of the participants ranged from 79(13.73% to 168(63.73% with a mean of 130.74(40.05% and SD of 21.51(10.84%. On the college self-efficacy scale, participants’ scores ranged from 62(40.79% to 152(100% with a mean of 114.29(77.10% and SD of 22.82(14.20%. On the Sf-36 form, participants scored 72.28±14.09% on average (Min=44.03%, Max=98.75%. The Spearman correlation coefficient test indicated that all correlations between variables were statistically significant (p<0.001. Conclusion: It can be concluded that adopting additional methods to increase self-efficacy and decrease stress amongst medical students in the academic population will lead to improved mental and physical health, which can help national improvement of science.

One of the most striking features of mathematics is the fact that we are much more certain about the mathematical knowledge we have than about what mathematical knowledge is knowledge of. Are numbers, sets, functions and groups physical entities of some kind? Are they objectively existing objects in some non-physical, mathematical realm? Are they ideas that are present only in the mind? Or do mathematical truths not involve referents of any kind? It is these kinds of questions that have encouraged philosophers and mathematicians alike to focus their attention on issues in the philosophy of mat

Mathematics for Physicists is a relatively short volume covering all the essential mathematics needed for a typical first degree in physics, from a starting point that is compatible with modern school mathematics syllabuses. Early chapters deliberately overlap with senior school mathematics, to a degree that will depend on the background of the individual reader, who may quickly skip over those topics with which he or she is already familiar. The rest of the book covers the mathematics that is usually compulsory for all students in their first two years of a typical university physics degree, plus a little more. There are worked examples throughout the text, and chapter-end problem sets. Mathematics for Physicists features: * Interfaces with modern school mathematics syllabuses * All topics usually taught in the first two years of a physics degree * Worked examples throughout * Problems in every chapter, with answers to selected questions at the end of the book and full solutions on a website This text will ...
Meaning in mathematics education
Valero, Paola; Hoyles, Celia; Skovsmose, Ole
2005-01-01
What does it mean to know mathematics? How does meaning in mathematics education connect to common sense or to the meaning of mathematics itself? How are meanings constructed and communicated and what are the dilemmas related to these processes? There are many answers to these questions, some of which might appear to be contradictory. Thus understanding the complexity of meaning in mathematics education is a matter of huge importance. There are twin directions in which discussions have developed - theoretical and practical - and this book seeks to move the debate forward along both dimensions while seeking to relate them where appropriate. A discussion of meaning can start from a theoretical examination of mathematics and how mathematicians over time have made sense of their work. However, from a more practical perspective, anybody involved in teaching mathematics is faced with the need to orchestrate the myriad of meanings derived from multiple sources that students develop of mathematical knowledge.

A so-called "effective" algorithm may require arbitrarily large finite amounts of time and space resources, and hence may not be practical in the real world. A "feasible" algorithm is one which only requires a limited amount of space and/or time for execution; the general idea is that a feasible algorithm is one which may be practical on today's or at least tomorrow's computers. There is no definitive analogue of Church's thesis giving a mathematical definition of feasibility; however, the most widely studied mathematical model of feasible computability is polynomial-time computability. Feasible Mathematics includes both the study of feasible computation from a mathematical and logical point of view and the reworking of traditional mathematics from the point of view of feasible computation. The diversity of Feasible Mathematics is illustrated by the. contents of this volume which includes papers on weak fragments of arithmetic, on higher type functionals, on bounded linear logic, on sub recursive definitions ...

Is mathematics a highly sophisticated intellectual game in which the adepts display their skill by tackling invented problems, or are mathematicians engaged in acts of discovery as they explore an independent realm of mathematical reality? Why does this seemingly abstract discipline provide the key to unlocking the deep secrets of the physical universe? How one answers these questions will significantly influence metaphysical thinking about reality. This book is intended to fill a gap between popular 'wonders of mathematics' books and the technical writings of the philosophers of mathematics.

The book then explains differential and integral calculus, covering topics, such as algebra of limits, the concept of continuity, the theorem of continuous functions (with examp
Philosophy and mathematics: interactions.
Rashed, Roshdi
From Plato to the beginnings of the last century, mathematics provided philosophers with methods of exposition, procedures of demonstration, and instruments of analysis. The unprecedented development of mathematics on the one hand, and the mathematicians' appropriation of Logic from the philosophers on the other hand, have given rise to two problems with which the philosophers have to contend: (1) Is there still a place for the philosophy of mathematics? and (2) To what extent is a philosophy of mathematics still possible? This article offers some reflections on these questions, which have preoccupied a good many philosophers and continue to do so.

Full Text Available The objective of mathematics education is not only preparingmathematicians but making well-informed citizens. This is a broad generalterms for objective of the teaching of mathematics. And, this might beimplemented as “accurate thorough knowledge” or “original logicalthinking”. So, teaching mathematics is not the conversation andtransmission of mathematical knowledge, but on the aim of preparing wellinformedcitizens trained in independent, critical thinking.By the mathematics, sciences become simple, clearer, and easier to bedeveloped. The mathematics is often applied for solving any problem ofother field of sciences, either in the physics such as astronomy, chemistry,technique; or social sciences such as economy, demography, and assurance.Those all need an analysis reading ability.Mathematical skill, therefore, relates strongly with the analysisreading ability in the human intellectual structure. This study is about therelationship between them. And, result of the study shows us as below:Both Mathematical skill and analysis reading ability possess the “high type”of thinking operation. Both also involve the same content of the abstractintelligent, i.e. symbolic and semantic contents. Last but not least, both alsouse the same product of thinking, i.e. units, classes, relations, and systems.Both can be transformed and have an implication.

Blomhøj, Morten; Jensen, Tomas Højgaard
2003-01-01
In this paper we introduce the concept of mathematical modelling competence, by which we mean being able to carry through a whole mathematical modelling process in a certain context. Analysing the structure of this process, six sub-competences are identified. Mathematical modelling competence...... cannot be reduced to these six sub-competences, but they are necessary elements in the development of mathematical modelling competence. Experience from the development of a modelling course is used to illustrate how the different nature of the sub-competences can be used as a tool for finding...... the balance between different kinds of activities in a particular educational setting. Obstacles of social, cognitive and affective nature for the students' development of mathematical modelling competence are reported and discussed in relation to the sub-competences....
Advanced engineering mathematics
Jeffrey, Alan
2001-01-01
Advanced Engineering Mathematics provides comprehensive and contemporary coverage of key mathematical ideas, techniques, and their widespread applications, for students majoring in engineering, computer science, mathematics and physics. Using a wide range of examples throughout the book, Jeffrey illustrates how to construct simple mathematical models, how to apply mathematical reasoning to select a particular solution from a range of possible alternatives, and how to determine which solution has physical significance. Jeffrey includes material that is not found in works of a similar nature, such as the use of the matrix exponential when solving systems of ordinary differential equations. The text provides many detailed, worked examples following the introduction of each new idea, and large problem sets provide both routine practice, and, in many cases, greater challenge and insight for students. Most chapters end with a set of computer projects that require the use of any CAS (such as Maple or Mathematica) th...
Mathematics of aperiodic order
Lenz, Daniel; Savinien, Jean
2015-01-01
What is order that is not based on simple repetition, that is, periodicity? How must atoms be arranged in a material so that it diffracts like a quasicrystal? How can we describe aperiodically ordered systems mathematically? Originally triggered by the – later Nobel prize-winning – discovery of quasicrystals, the investigation of aperiodic order has since become a well-established and rapidly evolving field of mathematical research with close ties to a surprising variety of branches of mathematics and physics. This book offers an overview of the state of the art in the field of aperiodic order, presented in carefully selected authoritative surveys. It is intended for non-experts with a general background in mathematics, theoretical physics or computer science, and offers a highly accessible source of first-hand information for all those interested in this rich and exciting field. Topics covered include the mathematical theory of diffraction, the dynamical systems of tilings or Delone sets, their cohomolog...
MATHEMATICAL MODEL MANIPULATOR ROBOTS
Directory of Open Access Journals (Sweden)
O. N. Krakhmalev
2015-12-01
Full Text Available A mathematical model to describe the dynamics of manipulator robots. Mathematical model are the implementation of the method based on the Lagrange equation and using the transformation matrices of elastic coordinates. Mathematical model make it possible to determine the elastic deviations of manipulator robots from programmed motion trajectories caused by elastic deformations in hinges, which are taken into account in directions of change of the corresponding generalized coordinates. Mathematical model is approximated and makes it possible to determine small elastic quasi-static deviations and elastic vibrations. The results of modeling the dynamics by model are compared to the example of a two-link manipulator system. The considered model can be used when performing investigations of the mathematical accuracy of the manipulator robots.

Mathematics as verbal behavior.
Marr, M Jackson
2015-04-01
"Behavior which is effective only through the mediation of other persons has so many distinguishing dynamic and topographical properties that a special treatment is justified and indeed demanded" (Skinner, 1957, p. 2). Skinner's demand for a special treatment of verbal behavior can be extended within that field to domains such as music, poetry, drama, and the topic of this paper: mathematics. For centuries, mathematics has been of special concern to philosophers who have continually argued to the present day about what some deem its "special nature." Two interrelated principal questions have been: (1) Are the subjects of mathematical interest pre-existing in some transcendental realm and thus are "discovered" as one might discover a new planet; and (2) Why is mathematics so effective in the practices of science and engineering even though originally such mathematics was "pure" with applications neither contemplated or even desired? I argue that considering the actual practice of mathematics in its history and in the context of acquired verbal behavior one can address at least some of its apparent mysteries. To this end, I discuss some of the structural and functional features of mathematics including verbal operants, rule-and contingency-modulated behavior, relational frames, the shaping of abstraction, and the development of intuition. How is it possible to understand Nature by properly talking about it? Essentially, it is because nature taught us how to talk. Copyright © 2015 Elsevier B.V. All rights reserved.

In this paper we describe the role that mathematics plays in measurement science at NIST. We first survey the history behind NIST's current work in this area, starting with the NBS Math Tables project of the 1930s. We then provide examples of more recent efforts in the application of mathematics to measurement science, including the solution of ill-posed inverse problems, characterization of the accuracy of software for micromagnetic modeling, and in the development and dissemination of mathematical reference data. Finally, we comment on emerging issues in measurement science to which mathematicians will devote their energies in coming years.

Mathematization in introductory physics
Brahmia, Suzanne M.
Mathematization is central to STEM disciplines as a cornerstone of the quantitative reasoning that characterizes these fields. Introductory physics is required for most STEM majors in part so that students develop expert-like mathematization. This dissertation describes coordinated research and curriculum development for strengthening mathematization in introductory physics; it blends scholarship in physics and mathematics education in the form of three papers. The first paper explores mathematization in the context of physics, and makes an original contribution to the measurement of physics students' struggle to mathematize. Instructors naturally assume students have a conceptual mastery of algebra before embarking on a college physics course because these students are enrolled in math courses beyond algebra. This paper provides evidence that refutes the validity of this assumption and categorizes some of the barriers students commonly encounter with quantification and representing ideas symbolically. The second paper develops a model of instruction that can help students progress from their starting points to their instructor's desired endpoints. Instructors recognize that the introductory physics course introduces new ideas at an astonishing rate. More than most physicists realize, however, the way that mathematics is used in the course is foreign to a large portion of class. This paper puts forth an instructional model that can move all students toward better quantitative and physical reasoning, despite the substantial variability of those students' initial states. The third paper describes the design and testing of curricular materials that foster mathematical creativity to prepare students to better understand physics reasoning. Few students enter introductory physics with experience generating equations in response to specific challenges involving unfamiliar quantities and units, yet this generative use of mathematics is typical of the thinking involved in

The reader will learn numerous results that often belong to neither the standard undergraduate nor graduate curriculum and will discover connections between classical and contemporary ideas in algebra, combinatorics, geometry, and topology. The reader's effort will be rewarded in seeing the harmony of each subject. The common thread in the selected subjects is their illustration of the unity and beauty of mathematics. Most lectures contain exercises, and solutions or answers are given to selected exercises. A special feature of the book is an abundance of drawings (more than four hundred), artwork by an accomplished artist, and about a hundred portraits of mathematicians. Almost every lecture contains surprises for even the seasoned researcher.

Presents a clear bridge between mathematics and the liberal arts Mathematics for the Liberal Arts provides a comprehensible and precise introduction to modern mathematics intertwined with the history of mathematical discoveries. The book discusses mathematical ideas in the context of the unfolding story of human thought and highlights the application of mathematics in everyday life. Divided into two parts, Mathematics for the Liberal Arts first traces the history of mathematics from the ancient world to the Middle Ages, then moves on to the Renaissance and finishes with the development of modern mathematics. In the second part, the book explores major topics of calculus and number theory, including problem-solving techniques and real-world applications. This book emphasizes learning through doing, presents a practical approach, and features: A detailed explanation of why mathematical principles are true and how the mathematical processes workNumerous figures and diagrams as well as hundreds of worked example...
Mathematics, anxiety, and the brain.
Moustafa, Ahmed A; Tindle, Richard; Ansari, Zaheda; Doyle, Margery J; Hewedi, Doaa H; Eissa, Abeer
2017-05-24
Given that achievement in learning mathematics at school correlates with work and social achievements, it is important to understand the cognitive processes underlying abilities to learn mathematics efficiently as well as reasons underlying the occurrence of mathematics anxiety (i.e. feelings of tension and fear upon facing mathematical problems or numbers) among certain individuals. Over the last two decades, many studies have shown that learning mathematical and numerical concepts relies on many cognitive processes, including working memory, spatial skills, and linguistic abilities. In this review, we discuss the relationship between mathematical learning and cognitive processes as well as the neural substrates underlying successful mathematical learning and problem solving. More importantly, we also discuss the relationship between these cognitive processes, mathematics anxiety, and mathematics learning disabilities (dyscalculia). Our review shows that mathematical cognition relies on a complex brain network, and dysfunction to different segments of this network leads to varying manifestations of mathematical learning disabilities.

This paper provides mathematicians and other persons interested in energy problems with some ideas of the kinds of mathematics being applied and a few ideas for further investigation both in the relevant mathematics and in mathematical modeling. This paper is not meant to be an extensive bibliography on the subject, but references are provided. The Conference emphasized large scale and economic considerations related to energy rather than specific technologies, but additional mathematical problems arising in current and future technologies are suggested. Several of the papers dealt with linear programming models of large scale systems related to energy. These included economic models, policy models, energy sector models for supply and demand and environmental concerns. One of the economic models utilized variational techniques including such things as the Hamiltonian, the Euler-Lagrange differential equation, transversality and natural boundary conditions

Symbiosis between mathematics and electromagnetism is analyzed in a simple and concise manner by taking a historical perspective. The universal tool character of mathematical models allowed the transfer of models from several branches of physics into the realm of electromagnetism by drawing analogies. The mutual interdependence between covariant formulation and tensor calculus is marked. The paper focuses on the guiding idea of field theory and Maxwell's equations. Likewise, geometrization of interactions in connection with gauge fields is also noted. (Author)

In this paper, we study foundational issues that we believe will help us develop a theoretically sound approach to constructing complex systems. The two theoretical approaches that have helped us understand and develop computational systems in the past are mathematics and linguistics. We describe some differences and strengths of the approaches, and propose a research program to combine the richness of linguistic reasoning with the precision of mathematics.

The extraordinary quantitative achievements of contemporary science often hide their qualitative dimension. In mathematics, the understanding of fundamental theoretical phenomena we have got today goes much beyond that achieved in previous periods. This also holds when it comes to the theorisation of mathematical practice.Philosophically, these changes remain largely to be properly analyzed. The present article will address this issue from the point of view of Bachelard's epistemology.

New mathematical cuneiform texts
Friberg, Jöran
2016-01-01
This monograph presents in great detail a large number of both unpublished and previously published Babylonian mathematical texts in the cuneiform script. It is a continuation of the work A Remarkable Collection of Babylonian Mathematical Texts (Springer 2007) written by Jöran Friberg, the leading expert on Babylonian mathematics. Focussing on the big picture, Friberg explores in this book several Late Babylonian arithmetical and metro-mathematical table texts from the sites of Babylon, Uruk and Sippar, collections of mathematical exercises from four Old Babylonian sites, as well as a new text from Early Dynastic/Early Sargonic Umma, which is the oldest known collection of mathematical exercises. A table of reciprocals from the end of the third millennium BC, differing radically from well-documented but younger tables of reciprocals from the Neo-Sumerian and Old-Babylonian periods, as well as a fragment of a Neo-Sumerian clay tablet showing a new type of a labyrinth are also discussed.

"Boyer and Merzbach distill thousands of years of mathematics into this fascinating chronicle. From the Greeks to Godel, the mathematics is brilliant; the cast of characters is distinguished; the ebb and flow of ideas is everywhere evident. And, while tracing the development of European mathematics, the authors do not overlook the contributions of Chinese, Indian, and Arabic civilizations. Without doubt, this is--and will long remain--a classic one-volume history of mathematics and mathematicians who create it." --William Dunham Author, Journey Through Genius, The Great Theorems of Mathematics "When we read a book like A History of Mathematics, we get the picture of a mounting structure, ever taller and broader and more beautiful and magnificent--and with a foundation, moreover, that is as untainted and as functional now as it was when Thales worked out the first geometrical theorems nearly 26 centuries ago." --From the Foreword by Isaac Asimov "One of the most useful and comprehensive general introductions t...

The purpose of this review is not to present a comprehensive description of all the mathematical tools used in nuclear medicine, but to emphasize the importance of the mathematical method in nuclear medicine and to elucidate some of the mathematical concepts currently used. We can distinguish three different areas in which mathematical support has been offered to nuclear medicine: Physiology, methodology and data processing. Nevertheless, the boundaries between these areas can be indistinct. It is impossible in a single article to give even an idea of the extent and complexity of the procedures currently usede in nuclear medicine, such as image processing, reconstruction from projections and artificial intelligence. These disciplines do not belong to nuclear medicine: They are already branches of engineering, and my interest will reside simply in revealing a little of the elegance and the fantastic potential of these new `allies` of nuclear medicine. In this review the mathematics of physiological interpretation and methodology are considered together in the same section. General aspects of data-processing methods, including image processing and artificial intelligence, are briefly analysed. The mathematical tools that are most often used to assist the interpretation of biological phenomena in nuclear medicine are considered; these include convolution and deconvolution methods, Fourier analysis, factorial analysis and neural networking.

DISCRETE MATHEMATICS/NUMBER THEORY
Mrs. Manju Devi*

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics such as integers, graphs, and statements do not vary smoothly in this way, but have distinct, separated values. Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis. Discrete objects can often be enumerated by ...

Mathematics is a powerful tool for describing and developing our knowledge of the physical world. It informs our understanding of subjects as diverse as music, games, science, economics, communications protocols, and visual arts. Mathematical thinking has its roots in the adaptive behavior of living creatures: animals must employ judgments about quantities and magnitudes in the assessment of both threats (how many foes) and opportunities (how much food) in order to make effective decisions, and use geometric information in the environment for recognizing landmarks and navigating environments. Correspondingly, cognitive systems that are dedicated to the processing of distinctly mathematical information have developed. In particular, there is evidence that certain core systems for understanding different aspects of arithmetic as well as geometry are employed by humans and many other animals. They become active early in life and, particularly in the case of humans, develop through maturation. Although these core systems individually appear to be quite limited in application, in combination they allow for the recognition of mathematical properties and the formation of appropriate inferences based upon those properties. In this overview, the core systems, their roles, their limitations, and their interaction with external representations are discussed, as well as possibilities for how they can be employed together to allow us to reason about more complex mathematical domains. © 2015 John Wiley & Sons, Ltd.

2005-01-01
A lot of economic problems can be formulated as constrained optimizations and equilibration of their solutions. Various mathematical theories have been supplying economists with indispensable machineries for these problems arising in economic theory. Conversely, mathematicians have been stimulated by various mathematical difficulties raised by economic theories. The series is designed to bring together those mathematicians who are seriously interested in getting new challenging stimuli from economic theories with those economists who are seeking effective mathematical tools for their research. The editorial board of this series comprises the following prominent economists and mathematicians: Managing Editors: S. Kusuoka (Univ. Tokyo), T. Maruyama (Keio Univ.). Editors: R. Anderson (U.C.

Mathematical grammar of biology
Yamagishi, Michel Eduardo Beleza
2017-01-01
This seminal, multidisciplinary book shows how mathematics can be used to study the first principles of DNA. Most importantly, it enriches the so-called “Chargaff’s grammar of biology” by providing the conceptual theoretical framework necessary to generalize Chargaff’s rules. Starting with a simple example of DNA mathematical modeling where human nucleotide frequencies are associated to the Fibonacci sequence and the Golden Ratio through an optimization problem, its breakthrough is showing that the reverse, complement and reverse-complement operators defined over oligonucleotides induce a natural set partition of DNA words of fixed-size. These equivalence classes, when organized into a matrix form, reveal hidden patterns within the DNA sequence of every living organism. Intended for undergraduate and graduate students both in mathematics and in life sciences, it is also a valuable resource for researchers interested in studying invariant genomic properties.

Basic mathematics for biochemists
Cornish-Bowden, Athel
1981-01-01
Some teachers of biochemistry think it positively beneficial for students to struggle with difficult mathematics. I do not number myself among these people, although I have derived much personal pleasure from the study of mathematics and from applying it to problems that interest me in biochemistry. On the contrary, I think that students choose courses in biochemistry out of interest in biochemistry and that they should not be encumbered with more mathematics than is absolutely required for a proper understanding of biochemistry. This of course includes physical chemistry, because a biochemist ignorant of physical chemistry is no biochemist. I have been guided by these beliefs in writing this book. I have laid heavy emphasis on those topics, such as the use of logarithms, that play an important role in biochemistry and often cause problems in teaching; I have ignored others, such as trigonometry, that one can manage without. The proper treatment of statistics has been more difficult to decide. Although it cle...
Principles of mathematical modeling
Dym, Clive
2004-01-01
Science and engineering students depend heavily on concepts of mathematical modeling. In an age where almost everything is done on a computer, author Clive Dym believes that students need to understand and "own" the underlying mathematics that computers are doing on their behalf. His goal for Principles of Mathematical Modeling, Second Edition, is to engage the student reader in developing a foundational understanding of the subject that will serve them well into their careers. The first half of the book begins with a clearly defined set of modeling principles, and then introduces a set of foundational tools including dimensional analysis, scaling techniques, and approximation and validation techniques. The second half demonstrates the latest applications for these tools to a broad variety of subjects, including exponential growth and decay in fields ranging from biology to economics, traffic flow, free and forced vibration of mechanical and other systems, and optimization problems in biology, structures, an...

Herbart's mathematical psychology.
Boudewijnse, G J; Murray, D J; Bandomir, C A
1999-08-01
J.F. Herbart (1824/1890b) provided a mathematical theory about how mental ideas (Vorstellungen) in consciousness at Time 1 (T1) could compete, possibly driving 1 or more Vorstellungen below a threshold of consciousness. At T1 a Vorstellung A could also fuse with another, B. If at a later T2, A resurfaced into consciousness, it could help B to re-resurface into consciousness. This article describes the historical and mathematical background of Herbart's theory, outlines the mathematical theory itself with the aid of computer graphics, and argues that the theory can be applied to the modern problem of predicting recognition latencies in short-term memory (Sternberg's task; Sternberg, 1966)

Heath, Thomas
2015-01-01
Originally published in 1949. This meticulously researched book presents a comprehensive outline and discussion of Aristotle's mathematics with the author's translations of the greek. To Aristotle, mathematics was one of the three theoretical sciences, the others being theology and the philosophy of nature (physics). Arranged thematically, this book considers his thinking in relation to the other sciences and looks into such specifics as squaring of the circle, syllogism, parallels, incommensurability of the diagonal, angles, universal proof, gnomons, infinity, agelessness of the universe, surface of water, meteorology, metaphysics and mechanics such as levers, rudders, wedges, wheels and inertia. The last few short chapters address 'problems' that Aristotle posed but couldn't answer, related ethics issues and a summary of some short treatises that only briefly touch on mathematics.

Perception determinants in learning mathematics
Mokhtar, Siti Fairus; Ali, Noor Rasidah; Rashid, Nurazlina Abdul
2015-05-01
This article described a statistical study of students' perception in mathematics. The objective of this study is to identify factors related to perception about learning mathematics among non mathematics' student. This study also determined the relationship between of these factors among non mathematics' student. 43 items questionnaires were distributed to one hundred students in UiTM Kedah who enrolled in the Business Mathematics course. These items were measured by using a semantic scale with the following anchors: 1 = strongly disagree to 7 = strongly agree. A factor analysis of respondents were identified into five factors that influencing the students' perception in mathematics. In my study, factors identified were attitude, interest, role of the teacher, role of peers and usefulness of mathematics that may relate to the perception about learning mathematics among non mathematics' student.

This volume is based on the lecture notes of the minicourses given in the frame of the school on Mathematical Control Theory held at the Abdus Salam ICTP from 3 to 28 September 2001. Mathematical Control Theory is a rapidly growing field which provides strict theoretical and computational tools for dealing with problems arising in electrical and aerospace engineering, automatics, robotics, applied chemistry, and biology etc. Control methods are also involved in questions pertaining to the development of countries in the South, such as wastewater treatment, agronomy, epidemiology, population dynamics, control of industrial and natural bio-reactors. Since most of these natural processes are highly nonlinear, the tools of nonlinear control are essential for the modelling and control of such processes. At present regular courses in Mathematical Control Theory are rarely included in the curricula of universities, and very few researchers receive enough background in the field. Therefore it is important to organize specific activities in the form of schools to provide the necessary background for those embarking on research in this field. The school at the Abdus Salam ICTP consisted of several minicourses intended to provide an introduction to various topics of Mathematical Control Theory, including Linear Control Theory (finite and infinite-dimensional), Nonlinear Control, and Optimal Control. The last week of the school was concentrated on applications of Mathematical Control Theory, in particular, those which are important for the development of non-industrialized countries. The school was intended primarily for mathematicians and mathematically oriented engineers at the beginning of their career. The typical participant was expected to be a graduate student or young post-doctoral researcher interested in Mathematical Control Theory. It was assumed that participants have sufficient background in Ordinary Differential Equations and Advanced Calculus. The volume

Concepts of modern mathematics
Stewart, Ian
1995-01-01
Some years ago, ""new math"" took the country's classrooms by storm. Based on the abstract, general style of mathematical exposition favored by research mathematicians, its goal was to teach students not just to manipulate numbers and formulas, but to grasp the underlying mathematical concepts. The result, at least at first, was a great deal of confusion among teachers, students, and parents. Since then, the negative aspects of ""new math"" have been eliminated and its positive elements assimilated into classroom instruction.In this charming volume, a noted English mathematician uses humor an

The study of activity vs. depth profiles in sediment cores of some man-made and natural ocurring radionuclides have shown to be a poweful tool for dating purposes. Nevertheless, in most cases, an adecuate interpretation of such profiles requires mathematical models. In this paper, by considering the sediment as a continuum, a general equation for diffusion of radionuclides through it is obtained. Consequentely, some previously published dating models are found to be particular solutions of such general advenction-diffusion problem. Special emphasis is given to the mathematical treatment of compactation effect and time dependent problems. (author)
Mathematical Astronomy in India
Plofker, Kim
Astronomy in South Asia's Sanskrit tradition, apparently originating in simple calendric computations regulating the timing of ancient ritual practices, expanded over the course of two or three millennia to include detailed spherical models, an endless variety of astrological systems, and academic mathematics in general. Assimilating various technical models, methods, and genres from the astronomy of neighboring cultures, Indian astronomers created new forms that were in turn borrowed by their foreign counterparts. Always recognizably related to the main themes of Eurasian geocentric mathematical astronomy, Indian astral science nonetheless maintained its culturally distinct character until Keplerian heliocentrism and Newtonian mechanics replaced it in colonial South Asia's academic mainstream.

During Edmund Husserl,s lifetime, modern logic and mathematics rapidly developed toward their current outlook and Husserl,s writings can be fruitfully compared and contrasted with both 19th century figures (Boole, Schroder, Weierstrass) as well as the 20th century characters (Heyting, Zermelo, Godel). Besides the more historical studies, the internal ones on Husserl alone and the external ones attempting to clarify his role in the more general context of the developing mathematics and logic, Husserl,s phenomenology offers also a systematically rich but little researched area of investigation.

Philosophy of mathematics today has transformed into a very complex network of diverse ideas, viewpoints, and theories. Sometimes the emphasis is on the ""classical"" foundational work (often connected with the use of formal logical methods), sometimes on the sociological dimension of the mathematical research community and the ""products"" it produces, then again on the education of future mathematicians and the problem of how knowledge is or should be transmitted from one generation to the next.

Early modern mathematical instruments.
Bennett, Jim
2011-12-01
In considering the appropriate use of the terms "science" and "scientific instrument," tracing the history of "mathematical instruments" in the early modern period is offered as an illuminating alternative to the historian's natural instinct to follow the guiding lights of originality and innovation, even if the trail transgresses contemporary boundaries. The mathematical instrument was a well-defined category, shared across the academic, artisanal, and commercial aspects of instrumentation, and its narrative from the sixteenth to the eighteenth century was largely independent from other classes of device, in a period when a "scientific" instrument was unheard of.

María F. Ayllón
2016-04-01
Full Text Available This work shows the relationship between the development of mathematical thinking and creativity with mathematical problem posing and solving. Creativity and mathematics are disciplines that do not usually appear together. Both concepts constitute complex processes sharing elements, such as fluency (number of ideas, flexibility (range of ideas, novelty (unique idea and elaboration (idea development. These factors contribute, among others, to the fact that schoolchildren are competent in mathematics. The problem solving and posing are a very powerful evaluation tool that shows the mathematical reasoning and creative level of a person. Creativity is part of the mathematics education and is a necessary ingredient to perform mathematical assignments. This contribution presents some important research works about problem posing and solving related to the development of mathematical knowledge and creativity. To that end, it is based on various beliefs reflected in the literature with respect to notions of creativity, problem solving and posing.

Questioning how mathematics has evolved over the centuries and for what reasons; how human endeavour and changes in the way we live have been dependent on mathematics, this book tells the story of the impact this intellectual activity has had across cultures and civilizations. It shows how, far from being just the obsession of an elite group of philosophers, priests and scientists, mathematics has in some shape or other entered every area of human activity. The mysterious tally sticks of prehistoric peoples and the terrestial maps used for trade, exploration and warfare; the perennial fascination with the motions of heavenly bodies and changing perspectives on the art and science of vision; all are testament to a mathematics at the heart of history. The path of this changing discipline is marked by a wealth of images, from medieval manuscripts to the unsettling art of Dali or Duchamp, from the austere beauty of Babylonian clay tablets to the delicate complexity of computer-generated images.

Putting Foundations Into Mathematics
Hubbard, G. L.
1972-01-01
For meaningful learning of mathematics, a learning set is required which demands that all things accepted as true should be demonstrable in terms of a paradigm appropriate to the child's cognitive development: preparatory, concrete-particular, concrete-general, formal-abstract. Future teachers should experience all paradigms to become aware that…
Cartier, Pierre; Heinzmann, Gerhard; Villani, Cédric
2016-01-01
This book challenges the views put forward by Pierre Cartier, one of the anchors of the famous Bourbaki group, and Cédric Villani, one of the most brilliant mathematicians of his generation, who received the Fields Medal in 2010. Jean Dhombres, mathematician and science historian, and Gerhard Heinzmann, philosopher of science and also a specialist in mathematics engage in a fruitful dialogue with the two mathematicians, prompting readers to reflect on mathematical activity and its social consequences in history as well as in the modern world. Cédric Villani’s popular success proves once again that a common awareness has developed, albeit in a very confused way, of the major role of mathematics in the construction and efficiency of natural sciences, which are at the origin of our technologies. Despite this, the idea that mathematics cannot be shared remains firmly entrenched, a perceived failing that has even been branded a lack of culture by vocal forces in the media as well as cultural and political esta...

Theological Metaphors in Mathematics
Directory of Open Access Journals (Sweden)
Krajewski Stanisław
2016-03-01
Full Text Available Examples of possible theological influences upon the development of mathematics are indicated. The best known connection can be found in the realm of infinite sets treated by us as known or graspable, which constitutes a divine-like approach. Also the move to treat infinite processes as if they were one finished object that can be identified with its limits is routine in mathematicians, but refers to seemingly super-human power. For centuries this was seen as wrong and even today some philosophers, for example Brian Rotman, talk critically about “theological mathematics”. Theological metaphors, like “God’s view”, are used even by contemporary mathematicians. While rarely appearing in official texts they are rather easily invoked in “the kitchen of mathematics”. There exist theories developing without the assumption of actual infinity the tools of classical mathematics needed for applications (For instance, Mycielski’s approach. Conclusion: mathematics could have developed in another way. Finally, several specific examples of historical situations are mentioned where, according to some authors, direct theological input into mathematics appeared: the possibility of the ritual genesis of arithmetic and geometry, the importance of the Indian religious background for the emergence of zero, the genesis of the theories of Cantor and Brouwer, the role of Name-worshipping for the research of the Moscow school of topology. Neither these examples nor the previous illustrations of theological metaphors provide a certain proof that religion or theology was directly influencing the development of mathematical ideas. They do suggest, however, common points and connections that merit further exploration.

The pragmatics of mathematics education vagueness and mathematical discourse
Rowland, Tim
2003-01-01
Drawing on philosophy of language and recent linguistic theory, Rowland surveys several approaches to classroom communication in mathematics. Are students intimidated by the nature of mathematics teaching? Many students appear fearful of voicing their understanding - is fear of error part of the linguistics of mathematics?

Mathematical Literacy: A new literacy or a new mathematics?
Directory of Open Access Journals (Sweden)
Renuka Vithal
2006-10-01
Full Text Available Mathematical Literacy is a ‘hot’ topic at present in most countries, whether it is referred to by that name, or in some cases as Numeracy, or Quantitative Literacy, or Matheracy, or as some part of Ethnomathematics, or related to Mathematics in Society. Questions continue to be asked about what is meant by mathematics in any concept of Mathematical Literacy and the use of the very word ‘Literacy’ in its association with Mathematics has been challenged. Its importance, however, lies in changing our perspective on mathematics teaching, away from the elitism so often associated with much mathematics education, and towards a more equitable, accessible and genuinely educational ideal.

The mathematics of superoscillations
Aharonov, Yakir; Sabadini, Irene; Tollaksen, J
2017-01-01
In the past 50 years, quantum physicists have discovered, and experimentally demonstrated, a phenomenon which they termed superoscillations. Aharonov and his collaborators showed that superoscillations naturally arise when dealing with weak values, a notion that provides a fundamentally different way to regard measurements in quantum physics. From a mathematical point of view, superoscillating functions are a superposition of small Fourier components with a bounded Fourier spectrum, which result, when appropriately summed, in a shift that can be arbitrarily large, and well outside the spectrum. The purpose of this work is twofold: on one hand the authors provide a self-contained survey of the existing literature, in order to offer a systematic mathematical approach to superoscillations; on the other hand, they obtain some new and unexpected results, by showing that superoscillating sequences can be seen of as solutions to a large class of convolution equations and can therefore be treated within the theory of...

Proof Auditing Formalised Mathematics
Directory of Open Access Journals (Sweden)
Mark Miles Adams
2016-01-01
Full Text Available The first three formalisations of major mathematical proofs have heralded a new age in formalised mathematics, establishing that informal proofs at the limits of what can be understood by humans can be checked by machine. However, formalisation itself can be subject to error, and yet there is currently no accepted process in checking, or even much concern that such checks have not been performed. In this paper, we motivate why we should be concerned about correctness, and argue the need for proof auditing, to rigorously and independently check a formalisation. We discuss the issues involved in performing an audit, and propose an effective and efficient auditing process. Throughout we use the Flyspeck Project, that formalises the Kepler Conjecture proof, to illustrate our point.
