(translation) I was interested by the development of a new edition of the book 1] "Die Grundstrukturen einer physikalischen Theorie." This has been possible, in spite of my old age, thanks to the contributions of Dr. G. Thurler. Without his indefatigable support and his essential and fundamental propositions, this new edition would not have been possible. The new edition clari?es and formulates more precisely the fundamental ideasofphysicaltheoriesinordertoavoidasmuchaspossibleanyambiguities. One begins theoretical physics with concepts that can be explained wi- out theories. Later, one introduces other concepts by theories known as "pre-theories." Thus it does not make sense to introduce concepts such as "state" without a pre-theory. The ?eld of physics is thus determined by the basic concepts introduced without the use of pre-theories. Also, it does not make sense to speak about the position and speed of an electron at a ?xed time. "Reality" is not however only the reality which is described by physical concepts. Thus, for example, colors, tones, joy, hate, and love are not physical concepts. But the demarcation of the physical concepts, and thus the demarcation of the ?eld of physics makes it possible to know more clearly, and thus to describemoreclearlyinthe future, the structureof realitybeyondthe domain ofphysics.The?eldoflifeandnotthatofdeathshouldbethegoalofmankind. Thus, I hope that this book can also become another small step for life.

In June 1954, the Atomic Energy Commission determined that J. Robert Oppenheimer, wartime director of the Manhattan Project and Father of the Atomic Bomb, was a security risk. Consequently, America's most prominent scientist was removed from government service. In contrast to historical and political explanations of the Oppenheimer case, Holloway explores the role that rhetoric played in Oppenheimer's demise. In doing so, the author draws attention to the symbolic nature of politics and character and highlights the significant interaction of political and scientific terminologies in American discourse.

Holloway's analysis and evaluation suggest that the accusations against Oppenheimer used the most powerful terms of the mid-1950s--communism, progress, and science--to legitimize the government's questionable action. Oppenheimer, for his part, failed to use his most strategic rhetorical resources in his defense, and therefore participated in his own ruin. Holloway highlights the rhetorical interaction among accusation, self-defense, and decision statements through a microscopic rhetorical analysis of the case's five central documents. An original extension and refinement of Kenneth Burke's cluster-agon method, which Holloway calls terminological algebra, is proposed as a systematic analytical tool consistent with Burke's theories. Recommended for critics of rhetoric and political communication.

This book is on soliton solutions of elliptical partial differential equations arising in quantum field theory, such as vortices, instantons, monopoles, dyons, and cosmic strings. The book presents in-depth description of the problems of current interest, forging a link between mathematical analysis and physics and seeking to stimulate further research in the area. Physically, it touches the major branches of field theory: classical mechanics, special relativity, Maxwell equations, superconductivity, Yang-Mills gauge theory, general relativity, and cosmology. Mathematically, it involves Riemannian geometry, Lie groups and Lie algebras, algebraic topology (characteristic classes and homotropy) and emphasizes modern nonlinear functional analysis. There are many interesting and challenging problems in the area of classical field theory, and while this area has long been of interest to algebraists, geometers, and topologists, it has gradually begun to attract the attention of more analysts. This book written for researchers and graduate students will appeal to high-energy and condensed-matter physicists, mathematicians, and mathematical scientists.

This book is the fourth in a series of lectures of the S eminaire Poincar e, whichis directed towards a large audience of physicists and of mathematicians. The goal of this seminar is to provide up-to-date information about general topics of great interest in physics. Both the theoretical and experimental aspects are covered, with some historical background. Inspired by the Bourbaki seminar in mathematics in its organization, hence nicknamed "Bourbaphi," the Poincar e Seminar is held twice a year at the Institut Henri Poincar e in Paris, with cont- butions prepared in advance. Particular care is devoted to the pedagogical nature of the presentations so as to ful?ll the goal of being readable by a large audience of scientists. This volume contains the seventh such Seminar, held in 2005. It is devoted to Einstein's 1905 papers and their legacy. After a presentation of Einstein's ep- temological approach to physics, and the genesis of special relativity, a cen- nary perspective is o?ered. The geometry of relativistic spacetime is explained in detail. Single photon experiments are presented, as a spectacular realization of Einstein's light quanta hypothesis. A previously unpublished lecture by Einstein, which presents an illuminating point of view on statistical physics in 1910, at the dawn of quantum mechanics, is reproduced. The volume ends with an essay on the historical, physical and mathematical aspects of Brownian motion. We hopethatthe publicationofthis serieswill servethe community ofphy- cists and mathematicians at the graduate student or professional level."

This book investigates in detail the emerging deep learning (DL) technique in computational physics, assessing its promising potential to substitute conventional numerical solvers for calculating the fields in real-time. After good training, the proposed architecture can resolve both the forward computing and the inverse retrieve problems. Pursuing a holistic perspective, the book includes the following areas. The first chapter discusses the basic DL frameworks. Then, the steady heat conduction problem is solved by the classical U-net in Chapter 2, involving both the passive and active cases. Afterwards, the sophisticated heat flux on a curved surface is reconstructed by the presented Conv-LSTM, exhibiting high accuracy and efficiency. Besides, the electromagnetic parameters of complex medium such as the permittivity and conductivity are retrieved by a cascaded framework in Chapter 4. Additionally, a physics-informed DL structure along with a nonlinear mapping module are employed to obtain the space/temperature/time-related thermal conductivity via the transient temperature in Chapter 5. Finally, in Chapter 6, a series of the latest advanced frameworks and the corresponding physics applications are introduced. As deep learning techniques are experiencing vigorous development in computational physics, more people desire related reading materials. This book is intended for graduate students, professional practitioners, and researchers who are interested in DL for computational physics.

This volume, dedicated to Prof. Gabriele Veneziano on the occasion of his retirement from CERN, starts as a broad historico-scientific study on the work on string theory and nonperturbative QCD that has been pioneered by Prof. Veneziano in the late 60s and early 70s. It goes on to examine the many ramifications this and similar early work has spawned over the past decades and the reader will find state-of-the art tutorial reviews on string cosmology, string dualities and symmetries, and much more.

The book includes a concise updated scientific biography of, and an interview with, Prof. Veneziano, in which he relates his personal views about the present and future of fundamental physics. This is followed by the commented draft of an unpublished paper of 1973 of his, anticipating interesting results which were rediscovered and published more than a decade later.

Overall, this volume is a vast and unique canvas where the re-examination of older and the presentation of newer results and insights are skillfully mixed with personal recollections of the contributing authors, most of them involved in the early days of string and quantum field theory, about Prof. Veneziano and the many interrelated topics considered.

With exoplanets being discovered daily, Earth is still the only planet we know of that is home to creatures who seek a coherent explanation for the structure, origins, and fate of the universe, and of humanity s place within it. Today, science and religion are the two major cultural entities on our planet that share this goal of coherent understanding, though their interpretation of evidence differs dramatically. Many scientists look at the known universe and conclude we are here by chance. The renowned astronomer and historian of science Owen Gingerich looks at the same evidence along with the fact that the universe is comprehensible to our minds and sees it as proof for the planning and intentions of a Creator-God. He believes that the idea of a universe without God is an oxymoron, a self-contradiction. God s Planet" exposes the fallacy in thinking that science and religion can be kept apart.

Gingerich frames his argument around three questions: Was Copernicus right, in dethroning Earth from its place at the center of the universe? Was Darwin right, in placing humans securely in an evolving animal kingdom? And was Hoyle right, in identifying physical constants in nature that seem singularly tuned to allow the existence of intelligent life on planet Earth? Using these episodes from the history of science, Gingerich demonstrates that cultural attitudes, including religious or antireligious beliefs, play a significant role in what passes as scientific understanding. The more rigorous science becomes over time, the more clearly God s handiwork can be comprehended."

For a meaningful understanding of physics, it is necessary to realise that this corpus of knowledge operates in a register different from natural thought. This book aims at situating the main trends of common reasoning in physics with respect to some essential aspects of accepted theory. It analyses a great many research results based on studies of pupils and students at various academic levels, involving a range of physical situations. It shows the impressive generality of the trends of common thought, as well as their resistance to teaching. The book's main focus is to underline to what extent natural thought is organised. As a result of this mapping out of trends of reasoning, some suggestions for teaching are presented; these have already influenced recent curricula in France. This book is intended for teachers and teacher trainers principally, but students can also benefit from it to improve their understanding of physics and of their own ways of reasoning.

Carl Friedrich von Weizsackers Aufbau der Physik, first published in 1985, was intended as an overview of his lifelong concern: an understanding of the unity of physics. That is, the idea of a quantum theory of binary alternatives (the so-called ur-theory), a unified quantum theoretical framework in which spinorial symmetry groups are considered to give rise to the structure of space and time.The book saw numerous reprints, but it was published in German only.The present edition, in English, provides a newly arranged and revised version, in which some original chapters and sections have been deleted, and a new chapter about further insights and results of ur-theoretic research of the late 1980's and 1990's, mainly by the work of Thomas Gornitz, has been included, as well as a general introduction to Weizsacker's Philosophy of Physics."

These two volumes constitute the Proceedings of the ConfA(c)rence MoshA(c) Flato, 1999'. Their spectrum is wide but the various areas covered are, in fact, strongly interwoven by a common denominator, the unique personality and creativity of the scientist in whose honor the Conference was held, and the far-reaching vision that underlies his scientific activity. With these two volumes, the reader will be able to take stock of the present state of the art in a number of subjects at the frontier of current research in mathematics, mathematical physics, and physics. Volume I is prefaced by reminiscences of and tributes to Flato's life and work. It also includes a section on the applications of sciences to insurance and finance, an area which was of interest to Flato before it became fashionable. The bulk of both volumes is on physical mathematics, where the reader will find these ingredients in various combinations, fundamental mathematical developments based on them, and challenging interpretations of physical phenomena. Audience: These volumes will be of interest to researchers and graduate students in a variety of domains, ranging from abstract mathematics to theoretical physics and other applications. Some parts will be accessible to proficient undergraduate students, and even to persons with a minimum of scientific knowledge but enough curiosity.

The Earth s magnetic and gravity field play an important role in global and regional geodynamics. Satellite exploration of these fields has received great attention in recent years. Research satellites such as CHAMP and GRACE as well as the ESA explorer GOCE apply new measurement techniques, thus allowing the recovery of the gravitational and magnetic field with unprecedented accuracy and resolution, spatial as well as temporal. Combined with terrestrial observations and computer models, this data will help develop a more detailed understanding of the Earth as a system. In Germany, many of the processing, modelling and interpreting methodologies for these new observation techniques are developed under the umbrella of the R&D-programme GEOTECHNOLOGIEN, funded by the Federal Ministry of Education and Research (BMBF). The research projects focus on a better understanding of the spatial and temporal variations in the magnetic and gravity field and their relationship to the dynamics of the Earth s interior and global change processes.

This volume presents the results of the multidisciplinary studies covered by the programme for the period 2005-2008. It includes the following topics: High-accuracy gravity field models, near-real-time provision and usage of CHAMP and GRACE atmospheric sounding, sea level variations, improved GRACE gravity time series and their validation by ocean bottom pressure measurements, integration of space geodetic techniques as a basis for the Global Geodetic-Geophysical Observing System (GGOS), high-resolution magnetic field models and global magnetisation maps and time-variable gravity and surface mass processes."

This book is not only an autobiography of the respected physicist and director of the Stanford Linear Accelerator Center, but a discussion and analysis of issues critical to the relationship between independent academic inquiry and imposed government orthodoxy. The book describes each phase of Dr. Panofsky's career in a way that clarifies the nature of the issues surrounding his work, and explains his chosen course of action.

The NATO Advanced Research Workshop "Painleve Transcendents, their Asymp totics and Physical Applications," held at the Alpine Inn in Sainte-Adele, near Montreal, September 2 -7, 1990, brought together a group of experts to discuss the topic and produce this volume. There were 41 participants from 14 countries and 27 lectures were presented, all included in this volume. The speakers presented reviews of topics to which they themselves have made important contributions and also re sults of new original research. The result is a volume which, though multiauthored, has the character of a monograph on a single topic. This is the theory of nonlinear ordinary differential equations, the solutions of which have no movable singularities, other than poles, and the extension of this theory to partial differential equations. For short we shall call such systems "equations with the Painleve property." The search for such equations was a very topical mathematical problem in the 19th century. Early work concentrated on first order differential equations. One of Painleve's important contributions in this field was to develop simple methods applicable to higher order equations. In particular these methods made possible a complete analysis of the equation;; = f(y', y, x), where f is a rational function of y' and y, with coefficients that are analytic in x. The fundamental result due to Painleve (Acta Math."

Combined into one volume for the first time, the updated and clarified "Exercises for the Feynman Lectures on Physics" provides comprehensive, hands-on practice in all the most important areas of physics--from Newtonian mechanics through the theory of relativity and quantum mechanics.
A perfect complement to "The Feynman Lectures on Physics," these exercises have all been assigned in Caltech's mandatory two-year introductory physics course, either when Richard Feynman was teaching it, or during the nearly two decades that followed when "The Feynman Lectures on Physics" was used as the textbook. With this modern, easy-to-use volume, students of physics will have a chance to apply what they have learned in the "Lectures" and to enhance and reinforce the concepts taught by the inimitable Richard Feynman.

This book deals with the subject of optical and electronic negative refraction (NR) and negative index materials NIM). Diverse approaches for achieving NR and NIM are covered, such as using photonic crystals, phononic crystals, split-ring resonators (SRRs) and continuous media, focusing of waves, guided-wave behavior, and nonlinear effects. It is perhaps the most comprehensive book on the new class of negative refraction materials, covering all aspects of negative refraction and negative index materials.

Kittel's Introduction to Solid State Physics, Global Edition, has been the standard solid state physics text for physics majors since the publication of its first edition over 60 years ago. The emphasis in the book has always been on physics rather than formal mathematics. This book is written with the goal that it is accessible to undergraduate students and consistently teachable. With each new edition, the author has attempted to add important new developments in the field without impacting its inherent content coverage. This Global Edition offers the advantage of expanded end-of-chapter problem sets.

Written as a set of tutorial reviews on both experimental facts and theoretical modelling, this volume is intended as an introduction and modern reference in the field for graduate students and researchers in biophysics, biochemistry and applied mathematics.

Definitions of what is meant by a heat-resistant polymer vary considerably. We have taken the term to mean a polymer which can be used, at least for short time periods, at temperatures from 150 DegreesC. The greatest problem which arises in writing a monograph on such materials is the tremendous amount of data that is available. More than 2000 references have been published on one heat-resistant polymer system alone over a period of little more than two years. The result is that a very high degree of selectivity must be exercised with respect to the information reproduced. We have chosen to restrict our coverage to polymers that have received at least some degree of commercial exploitation and to details of their methods of preparation, their thermal and thermo-oxidative stabilities and modes of degradation, and their properties at elevated temperatures. It must be emphasized that other properties not cited, e. g. , hydrolytic and chemical stability, and resistance to ultraviolet radiation, may be equally important in particular uses of these materials. The "older" heat-resistant polymers, e. g. , the thermosets and some of the fluorine-containing materials, are not dealt with in such depth as are the "newer" polymers with aromatic and/or heterocyclic rings in the chain. This is because books have been available for some time on the well-established commercial polymers and developments in them have not been as marked re cently as in the aromatic and heterocyclic macromolecules.

The book presents current research progress on hydrogen storage alloys, with a special focus on their applications in batteries. Background, formation mechanisms, electrochemical characteristics, and effects of elemental substitution are covered. Provides an up-to-date overview of the theme for experienced researchers, while including enough fundamentals to serve as a handy, practical introduction for newcomers to the field.

This volume of the Handbook illustrates the rich variety of topics covered by rare earth science. Three chapters are devoted to the description of solid state compounds: skutterudites (Chapter 211), rare earth -antimony systems (Chapter 212), and rare earth-manganese perovskites (Chapter 214). Two other reviews deal with solid state properties: one contribution includes information on existing thermodynamic data of lanthanide trihalides (Chapter 213) while the other one describes optical properties of rare earth compounds under pressure (Chapter 217). Finally, two chapters focus on solution chemistry. The state of the art in unraveling solution structure of lanthanide-containing coordination compounds by paramagnetic nuclear magnetic resonance is outlined in Chapter 215. The potential of time-resolved, laser-induced emission spectroscopy for the analysis of lanthanide and actinide solutions is presented and critically discussed in Chapter 216.

Many recent advances in modelling within the applied sciences and engineering have focused on the increasing importance of sensitivity analyses. For a given physical, financial or environmental model, increased emphasis is now placed on assessing the consequences of changes in model outputs that result from small changes or errors in both the hypotheses and parameters. The approach proposed in this book is entirely new and features two main characteristics. Even when extremely small, errors possess biases and variances. The methods presented here are able, thanks to a specific differential calculus, to provide information about the correlation between errors in different parameters of the model, as well as information about the biases introduced by non-linearity. The approach makes use of very powerful mathematical tools (Dirichlet forms), which allow one to deal with errors in infinite dimensional spaces, such as spaces of functions or stochastic processes. The method is therefore applicable to non-elementary models along the lines of those encountered in modern physics and finance. This text has been drawn from presentations of research done over the past ten years and that is still ongoing. The work was presented in conjunction with a course taught jointly at the Universities of Paris 1 and Paris 6. The book is intended for students, researchers and engineers with good knowledge in probability theory.
