Taschenbuch. Zustand: Neu. Neuware - Richard Feynman's never previously published doctoral thesis formed the heart of much of his brilliant and profound work in theoretical physics. Entitled 'The Principle of Least Action in Quantum Mechanics,' its original motive was to quantize the classical action-at-a-distance electrodynamics. Because that theory adopted an overall space-time viewpoint, the classical Hamiltonian approach used in the conventional formulations of quantum theory could not be used, so Feynman turned to the Lagrangian function and the principle of least action as his points of departure.The result was the path integral approach, which satisfied -- and transcended -- its original motivation, and has enjoyed great success in renormalized quantum field theory, including the derivation of the ubiquitous Feynman diagrams for elementary particles. Path integrals have many other applications, including atomic, molecular, and nuclear scattering, statistical mechanics, quantum liquids and solids, Brownian motion, and noise theory. It also sheds new light on fundamental issues like the interpretation of quantum theory because of its new overall space-time viewpoint.The present volume includes Feynman's Princeton thesis, the related review article 'Space-Time Approach to Non-Relativistic Quantum Mechanics' [Reviews of Modern Physics 20 (1948), 367-387], Paul Dirac's seminal paper 'The Lagrangian in Quantum Mechanics'' [Physikalische Zeitschrift der Sowjetunion, Band 3, Heft 1 (1933)], and an introduction by Laurie M Brown.…

To conclude the book, the ideas of grand unification are described, and finally, some applications to astrophysics are discussed.Your guide to this exciting world is an author who, together with the originator of the idea of quarks, Murray Gell-Mann, has played an important role in the development of the theory of quantum chromodynamics and the concept of grand unification.…

Taschenbuch. Zustand: Neu. Neuware - This book offers a refreshing view of leadership as a psycho-social phenomenon. Attention is drawn to the conceptual muddle which underlies much of managerial practices, particularly in the selection and development of future leaders. Also demonstrated is the conceptual muddle through semantic analysis of the vocabulary used in defining leadership in different languages. The concept of leadership from four different perspectives is examined in detail: leadership as a universal and natural phenomenon; membership and social roles; leadership as a collective process; conceptual models.In addition to the theoretical models, the author discusses patterns of influence and use and abuse of power. Consistent with his emphasis on the reciprocal nature of leadership, he complements his analysis of leading behavior by insightful analysis of the phenomenon of obedience: the psychological and cultural foundations of obedience; patterns of obedience; the collusion of leaders and followers in the abuse of power.The author's conceptualization of leadership challenges much of our conventional wisdom and traditional notions. He questions, for example, the universality of intelligence, dominance, aggressiveness and extraversion as predictors of leadership potential. Instead of imposing an ideal model of leadership, he lays the philosophical foundations that allow institutions to make their own choice of the model (or models) best suited for their values and unique historical circumstances. As such, the book can best be described as an interdisciplinary and cross-cultural guide for policy makers, particularly those concerned with the selection and training of leaders.…

Taschenbuch. Zustand: Neu. Neuware - This book introduces an approach to protein folding from the point of view of kinetic theory. There is an abundance of data on protein folding, but few proposals are available on the mechanism driving the process. Here, presented for the first time, are suggestions on possible research directions, as developed by the author in collaboration with C C Lin.The first half of this invaluable book contains a concise but relatively complete review of relevant topics in statistical mechanics and kinetic theory. It includes standard topics such as thermodynamics, the Maxwell-Boltzmann distribution, and ensemble theory. Special discussions include the dynamics of phase transitions, and Brownian motion as an illustration of stochastic processes.The second half develops topics in molecular biology and protein structure, with a view to discovering mechanisms underlying protein folding. Attention is focused on the energy flow through the protein in its folded state. A mathematical model, based on the Brownian motion of coupled harmonic oscillators, is worked out in the appendix.…

Taschenbuch. Zustand: Neu. Neuware - This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle-Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science -- the theory that life originated on Earth in a warm primordial soup.A Journey with Fred Hoyle is an intriguing book that traces the progress of a collaboration spanning 40 years, through a sequence of personal reflections, anecdotes and reminiscences. Ideas that were thought heretical 25 years ago are now quietly slipping into the domain of orthodox science.…

Taschenbuch. Zustand: Neu. Neuware - This book covers comprehensive bifurcation theory and its applications to dynamical systems and partial differential equations (PDEs) from science and engineering, including in particular PDEs from physics, chemistry, biology, and hydrodynamics.The book first introduces bifurcation theories recently developed by the authors, on steady state bifurcation for a class of nonlinear problems with even order nondegenerate nonlinearities, regardless of the multiplicity of the eigenvalues, and on attractor bifurcations for nonlinear evolution equations, a new notion of bifurcation.With this new notion of bifurcation, many longstanding bifurcation problems in science and engineering are becoming accessible, and are treated in the second part of the book. In particular, applications are covered for a variety of PDEs from science and engineering, including the Kuramoto-Sivashinsky equation, the Cahn-Hillard equation, the Ginzburg-Landau equation, reaction-diffusion equations in biology and chemistry, the Benard convection problem, and the Taylor problem. The applications provide, on the one hand, general recipes for other applications of the theory addressed in this book, and on the other, full classifications of the bifurcated attractor and the global attractor as the control parameters cross certain critical values, dictated usually by the eigenvalues of the linearized problems. It is expected that the book will greatly advance the study of nonlinear dynamics for many problems in science and engineering.…

Buch. Zustand: Neu. Neuware - Environmental economics, which used to be on the periphery of the economics discipline, is fast becoming mainstream as concern for the environment grows. Practitioners in other disciplines (e.g. engineering, science, natural resource management, social sciences) are increasingly faced with environmental problems that have an economic component. This invaluable book fills an important gap in the literature by teaching both economists and non-economists how to use economic tools to address environmental problems.The book is divided into three parts. Part I introduces theoretical concepts, including chapters on ecological economics and basic microeconomics for the non-specialist. Part II introduces tools for environmental policy analysis, while Part III discusses global environmental issues. The material is presented in an engaging manner with extensive use of graphs and diagrams to explain the key concepts. Exercises and an extensive bibliography are provided at the end of each chapter.…

Taschenbuch. Zustand: Neu. Neuware - Quantum mechanics is a difficult subject for students to learn after years of rigorous training in classical physics. In quantum mechanics they have to abandon what they have laboriously learned and adopt a new system of thinking.In the previous edition of this book, the author reformulated classical mechanics as a classical theory with an undetermined constant. As the constant approaches zero the theory reduces to Newton's exactly, but when set equal to the Planck constant the theory reduces to the Schrödinger representation of quantum mechanics. Thus the new theory, at least in its mathematical form, can be learned without ramifications and complexity. Over the years, the book has shepherded the growth of a generation of physicists.In this expanded edition, a similar trick is applied to introduce matrix mechanics. The matrix formulation presented allows quantum theory to be generalized to new physical systems such as electron spin, which cannot be done by the Schrödinger approach.The result is a textbook which promises to provide a future generation of students a clear, usable and authoritative resource to study the fundamentals of quantum mechanics. Twenty new problems are added to existing chapters.…

Buch. Zustand: Neu. Neuware - During World War II, nations raced to construct the world's first nuclear weapon that would determine the future of the world. The Manhattan Project, one of the most significant achievements of the 20th century, was the culmination of America's war effort.Today, although the issue of nuclear weapons frequently dominates world politics, few are aware of the history behind its development. Part I of this book, comprised of papers from the Atomic Heritage Foundation's Symposium on the Manhattan Project, recounts the history of this remarkable effort and reflects upon its legacy.Most of the original structures of the Manhattan Project have been inaccessible to the public and in recent years, have been stripped of their equipment and slated for demolition. Part II proposes a strategy for preserving these historical artifacts for the public and future generations.This book has been selected for coverage in: - Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)- Index to Social Sciences & Humanities Proceedings(R) (ISSHP(R) / ISI Proceedings)- Index to Social Sciences & Humanities Proceedings (ISSHP CDROM version / ISI Proceedings)- CC Proceedings -- Engineering & Physical Sciences. …

Taschenbuch. Zustand: Neu. Neuware - The aim of this book is to acquaint the reader with what the author regards as the most basic characteristics of quasicrystals -- structure, formation and stability, properties -- in relationship with the applications of quasicrystalline materials.Quasicrystals are fascinating substances that form a family of specific structures with strange physical and mechanical properties as compared to those of metallic alloys. This, on the one hand, is stimulating intensive research to understand the most basic properties of quasicrystals in the frame of a generalized crystallography. On the other hand, these properties open the way to technological applications, demonstrated or potential, mostly regarding energy savings.This valuable book discusses those various facets of quasicrystals in five chapters, ending with the author's own interpretation of the properties with respect to their unique structure.…

Buch. Zustand: Neu. Neuware - As became apparent after the tragic events of September 11, 2001, terrorist groups are increasingly using the Internet as a communication and propaganda tool where they can safely communicate with their affiliates, coordinate action plans, raise funds, and introduce new supporters to their networks. This is evident from the large number of web sites run by different terrorist organizations, though the URLs and geographical locations of these web sites are frequently moved around the globe. The wide use of the Internet by terrorists makes some people think that the risk of a major cyber-attack against the communication infrastructure is low. However, this situation may change abruptly once the terrorists decide that the Net does not serve their purposes anymore and, like any other invention of our civilization, deserves destruction.Fighting Terror in Cyberspace is a unique volume, which provides, for the first time, a comprehensive overview of terrorist threats in cyberspace along with state-of-the-art tools and technologies that can deal with these threats in the present and in the future. The book covers several key topics in cyber warfare such as terrorist use of the Internet, the Cyber Jihad, data mining tools and techniques of terrorist detection on the web, analysis and detection of terror financing, and automated identification of terrorist web sites in multiple languages. The contributors include leading researchers on international terrorism, as well as distinguished experts in information security and cyber intelligence. This book represents a valuable source of information for academic researchers, law enforcement and intelligence experts, and industry consultants who are involved in detection, analysis, and prevention of terrorist activities on the Internet.…

The themes are conveyed in a form that only requires a basic knowledge of mathematics, but the methods are described in sufficient detail to enable their computer implementation.The book describes the main techniques and facilities of contemporary cryptography, proving key results along the way. The contents of the first five chapters can be used for one-semester course.…

Buch. Zustand: Neu. Neuware - Turbulence is the most fundamental and, simultaneously, the most complex form of fluid flow. However, because an understanding of turbulence requires an understanding of laminar flow, both are explored in this book.Groundwork is laid by careful delineation of the necessary physical, mathematical, and numerical requirements for the studies which follow, and include discussions of N-body problems, classical molecular mechanics, dynamical equations, and the leap frog formulas for very large systems of second order ordinary differential equations.Molecular systems are studied first in both two and three dimensions. Extension into the large is also of great interest, and it is for this purpose that we develop particle mechanics, which uses lump massing of molecules. All calculations are limited to a personal scientific computer, so that the methods can be utilized readily by others.…

Buch. Zustand: Neu. Neuware - Reservoir simulation, or modeling, is one of the most powerful techniques currently available to the reservoir engineer. The author, Prof Leonard F Koederitz, (Distinguished Teaching Professor Emeritus at the University of Missouri-Rolla) is a highly notable author and teacher, with many teaching awards. This book has been developed over his twenty years in teaching to undergraduate petroleum engineering students, with the knowledge that they would in all likelihood be model-users, not developers.Most other books on reservoir simulation deal with simulation theory and development. For this book, however, the author has performed model studies and debugged user problems; while many of these problems were actual model errors (especially early on), a fair number of the discrepancies resulted from a lack of understanding of the simulator capabilities, or inappropriate data manipulation. The book reflects changes in both simulation concepts and philosophy over the years, by staying with 'tried and true' simulation practices as well as exploring new methods which could be useful in applied modeling.…
