The beat of a different drum : the life and science of Richard Feynman by Jagdish Mehra( Book )

28 editions published between 1994 and 2000 in English and held by 1,027 WorldCat member libraries worldwide

Feynman had a unified view of physics and nature: he took the whole of nature as the arena of his science and imagination. Jagdish Mehra personally knew Feynman for thirty years. In 1980 Feynman suggested he might do what he had already done for Heisenberg, Pauli, and Dirac, that is write a definitive account of his life, science, and personality. Mehra instantly agreed and subsequently spent several weeks talking to him. After Feynman's death Mehra interviewed almost eighty people who had known him and aspects of his work. This book draws on this unique material and on Feynman's remarkable writings. It covers his childhood, his three marriages, his extraordinary range of interests. But most important, it deals with his scientific work in far greater detail than in any other biographical work on Feynman. What has emerged is a truly authoritative account of Feynman's life and achievements

The Solvay Conferences on Physics : aspects of the development of physics since 1911 by Jagdish Mehra( Book )

18 editions published in 1975 in English and Dutch and held by 328 WorldCat member libraries worldwide

Jagdish Mehra's historical account of the Solvay Conferences from 1911 to 1973 demonstrates not only the great influence which these conferences have had on the development of modern physics, but it also shows clearly how far-sighted and well planned were the intentions of Ernest Solvay when he took the initiative for organizing a new type of international conferences. In contrast to the conventional meetings in which reports are given on the successful solution of scientific problems, the Solvay Conferences were conceived to help directly in solving specific problems of unusual difficulty. The importance of the quantum structure of Nature had become well under stood already by 1911, but at that time there was no hope for an answer to the ex tremely difficult new questions posed by the atomic phenomena. The new conferences should therefore be devoted primarily to thorough discussions of such problems be tween a small number of the most competent physicists, and Ernest Solvay was guided by the hope that the discussions would eventually lead to a real and substantial progress. The earliest Solvay Conferences which I attended were those of 1927, 1930 and 1933, and they served this purpose extremely well. In 1926 the mathematical formalism of quantum-and wave-mechanics approached its final shape, but the interpretation was still controversial. Schrodinger hoped that his matter waves could be considered as waves in three-dimensional space and time, and that the discontinuous feature of quantum 'jumps' could be avoided thereby
Climbing the mountain : the scientific biography of Julian Schwinger by K. A Milton( Book )

26 editions published between 2000 and 2008 in English and held by 325 WorldCat member libraries worldwide

"Julian Schwinger was one of the leading theoretical physicists of the twentieth century. His contributions are as important, and as pervasive, as those of Richard Feynman, with whom (and with Sin-itiro Tomonaga) he shared the 1965 Nobel Prize for Physics. Yet, while Feynman is universally recognized as a cultural icon, Schwinger is little known even to many within the physics community. This biography aims to describe Schwinger's life and research contributions to a wider audience." "This biography describes the many strands of his research life, while tracing the personal life of this private and gentle genius."--Jacket
Einstein, physics and reality by Jagdish Mehra( Book )

12 editions published between 1999 and 2000 in English and Undetermined and held by 298 WorldCat member libraries worldwide

Albert Einstein was one of the principal founders of the quantum and relativity theories. Until 1925, when the Bose-Einstein statistics was discovered, he made great contributions to the foundations of quantum theory. However, after the discovery of quantum mechanics by Heisenberg and wave mechanics by Schrödinger, with the consequent development of the principles of uncertainty and complementarity, it would seem that Einstein's views completely changed. In his theory of the Brownian motion, Einstein had invoked the theory of probability to establish the reality of atoms and molecules; but, in 1916-17, when he wished to predict the exact instant when an atom would radiate - and developed his theory of the A and B coefficients - he wondered whether the "quantum absorption and emission of light could ever be understood in the sense of the complete causality requirement, or would a statistical residue remain? I must admit that there I lack the courage of my convictions. But I would be very unhappy to renounce complete causality," as he wrote to his friend Max Born. However, he wrote later to Born that quantum mechanics "is certainly imposing," but "an inner voice tells me that it is not the real thing ... It does not bring us closer to the secret of the 'Old One.' I, at any rate, am convinced that He is not playing at dice." At the 1927 and 1930 Solvay Conferences on Physics in Brussels, Einstein engaged in profound discussions with Niels Bohr and others about his conviction regarding classical determinism versus the statistical causality of quantum mechanics. To the end of his life he retained his belief in a deterministic philosophy. This highly interesting book explores Einstein's views on the nature and structure of physics and reality
The quantum principle : its interpretation and epistemology by Jagdish Mehra( Book )

22 editions published between 1972 and 1974 in English and held by 294 WorldCat member libraries worldwide

This study deals with the development of, and the current discussion about, the interpretation of quantum mechanics. The following topics are discussed: 1. The Copenhagen In terpretation; 2. Formal Problems of Quantum Mechanics; 3. Process of Measurement and the Equation of Motion; 4. Macroscopic Level of Description; 5. Search for Hidden Variables; 6. The Notion of 'Reality' and the Epistemology of Quantum Mechanics; and 7. Quantum Mechanics and the Explanation of Life. The Bohr-Einstein dialogue on the validity of the quan tum mechanical description of physical reality lasted over two decades. Since the early nineteen-fifties, Eugene Wigner has provided much of the point and counterpoint of the continuing discussion on the interpretation and epistemolo gy of quantum mechanics. We have explored Wigner's views in some detail against the background of historical develop ment and current debate. Professor Eugene Wigner has sustained me over many years in my work on the conceptual development of mod ern physics by his kindness and encouragement. This study owes its existence to his direct inspiration, and to his suggestion to me in April 1971 that it would be of interest to write an account of the interpretation of quantum me chanics and the current discussion about it. XII PREFACE This study was completed in September 1972. Signifi cant new developments have occurred since then in the dis cussion of questions related to the epistemology of quan tum mechanics
Physical reality and mathematical description by Charles P Enz( Book )

16 editions published in 1974 in 3 languages and held by 288 WorldCat member libraries worldwide

This collection of essays is intended as a tribute to Josef Maria Jauch on his sixtieth birthd~. Through his scientific work Jauch has justly earned an honored name in the community of theo retical physicists. Through his teaching and a long line of dis tinguished collaborators he has put an imprint on modern mathema tical physics. A number of Jauch's scientific collaborators, friends and admirers have contributed to this collection, and these essays reflect to some extent Jauch's own wide interests in the vast do main of theoretical physics. Josef Maria Jauch was born on 20 September 1914, the son of Josef Alois and Emma (nee Conti) Jauch, in Lucerne, Switzerland. Love of science was aroused in him early in his youth. At the age of twelve he came upon a popular book on astronomy, and an exam ple treated in this book mystified him. It was stated that if a planet travels around a centre of Newtonian attraction with a pe riod T, and if that planet were stopped and left to fall into the centre from any point of the circular orbit, it would arrive at the centre in the time T/I32. Young Josef puzzled about this for several months until he made his first scientific discovery : that this result could be derived from Kepler's third law in a quite elementary way

The collected works of Eugene Paul Wigner by Eugene Paul Wigner( Book )

11 editions published between 1993 and 2001 in English and German and held by 214 WorldCat member libraries worldwide

Eugene Wigner is one of the few giants of 20th-century physics. His early work helped to shape quantum mechanics, he laid the foundations of nuclear physics and nuclear engineering, and he contributed significantly to solid-state physics. His philosophical and political writings are widely known. All his works will be reprinted in Eugene Paul Wigner's Collected Workstogether with descriptive annotations by outstanding scientists. The present volume begins with a short biographical sketch followed by Wigner's papers on group theory, an extremely powerful tool he created for theoretical quantum physics. They are presented in two parts. The first, annotated by B. Judd, covers applications to atomic and molecular spectra, term structure, time reversal and spin. In the second, G. Mackey introduces to the reader the mathematical papers, many of which are outstanding contributions to the theory of unitary representations of groups, including the famous paper on the Lorentz group

The completion of quantum mechanics, 1926-1941 by Jagdish Mehra( Book )

17 editions published between 2000 and 2005 in English and held by 153 WorldCat member libraries worldwide

Quantum Theory, together with the principles of special and general relativity, constitute a scientific revolution that has profoundly influenced the way in which we think about the universe and the fundamental forces that govern it. The Historical Development of Quantum Theory is a definitive historical study of that scientific work and the human struggles that accompanied it from the beginning. Drawing upon such materials as the resources of the Archives for the History of Quantum Physics, the Niels Bohr Archives, and the archives and scientific correspondence of the principal quantum physicists, as well as Jagdish Mehra's personal discussions over many years with most of the architects of quantum theory, the authors have written a rigorous scientific history of quantum theory in a deeply human context. This multivolume work presents a rich account of an intellectual triumph: a unique analysis of the creative scientific process. The Historical Development of Quantum Theory is science, history, and biography, all wrapped in the story of a great human enterprise. Its lessons will be an aid to those working in the sciences and humanities alike
