Based upon the proceedings of the First International Conference on the History of General Relativity, held at Boston University's Osgood Hill Conference Center, North Andover, Massachusetts, 8-11 May 1986, this volume brings together essays by twelve prominent historians and philosophers of science and physicists. The topics range from the development of general relativity (John Norton, John Stachel) and its early reception (Carlo Cattani, Michelangelo De Maria, Anne Kox), through attempts to understand the physical implications of the theory (Jean Eisenstaedt, Peter Havas) and to quantize it (Peter G. Bergmann), to elaborations of the theory into a unified theory of electromagnetism and gravitation (Vladimir P. Vizgin, Michel Biezunski), and considerations of its cosmological extensions (Pierre Kerszberg, George F.R. Ellis). This is the first volume to survey many of the most important questions in the history of general relativity, with many of the contributions drawing upon such original resources as the Einstein Archive. It is hoped that it will stimulate much-needed further research in this hitherto neglected area.

Comme le suggère le sobriquet « Zweistein », Wolfgang Pauli fut considéré par la communauté des théoriciens de la physique comme son membre le plus éminent après Albert Einstein. Durant plus de trente-cinq ans, les deux hommes entretinrent des relations intellectuelles et personnelles. Cet article analyse les relations entre quatre thèmes récurrents de leurs discussions. 1) La théorie de la relativité: à l'âge de 20 ans, Pauli préparait un manuel qui fera autorité sur la relativité, manuel qu'il révisera vers la fin de sa vie et qui demeure incomparable aux yeux des physiciens et des historiens de la physique. 2) La théorie du champ unifié: même s'il éprouvait de la sympathie, à l'origine, pour les recherches d'Einstein en vue d'une unification des théories de l'électromagnétisme et de la gravitation, à laquelle il apporta plusieurs contributions majeures, Pauli en vint à considérer une telle entreprise comme stérile. 3) Les fondements de la mécanique quantique: le jugement négatif porté par Pauli sur le programme de recherche d'Einstein s'accentua en raison de leur profond désaccord sur le rôle que la mécanique quantique était appelée à jouer dans les développements futurs de la physique théorique. 4) La gravitation quantique: Pauli reconnaissait toutefois que, tant qu'une réconciliation fructueuse de la mécanique quantique et de la relativité générale ne serait pas accomplie - réconciliation qui nous échappe toujours-, les scientifiques ne pourraient ignorer le défi qu'Einstein adressait à la mécanique quantique.

In three volumes, a distinguished group of scholars from a variety of disciplines in the natural and social sciences, the humanities and the arts contribute essays in honor of Robert S. Cohen, on the occasion of his 70th birthday. The range of the essays, as well as their originality, and their critical and historical depth, pay tribute to the extraordinary scope of Professor Cohen's intellectual interests, as a scientist-philosopher and a humanist, and also to his engagement in the world of social and political practice. Science, Mind and Art, Volume III of Essays in honor of Robert S. Cohen focuses on issues in contemporary epistemology, aesthetics, and philosophy of mind as well as on the relations of science and human values in ethical and religious thought. It also has important new work in contemporary metaphysics, as well as in the history of philosophy, and on questions of multiculturalism in science education. Contributors include Paul Feyerabend, Adolf Grünbaum, Joseph Margolis, Joëlle Proust, Erazim Kohak, Elie Wiesel, Miriam Bienenstock, and John Silber, among others.

After 1905, Einstein's miraculous year, physics would never be the same again. In those twelve months, Einstein shattered many cherished scientific beliefs with five extraordinary papers that would establish him as the world's leading physicist. This book brings those papers together in an accessible format. The best-known papers are the two that founded special relativity: On the Electrodynamics of Moving Bodies and Does the Inertia of a Body Depend on Its Energy Content? In the former, Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. In the second, he asserted the equivalence of mass and energy, which would lead to the famous formula E = mc 2 . The book also includes On a Heuristic Point of View Concerning the Production and Transformation of Light , in which Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921. The fourth paper also led to a Nobel Prize, although for another scientist, Jean Perrin. On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat concerns the Brownian motion of such particles. With profound insight, Einstein blended ideas from kinetic theory and classical hydrodynamics to derive an equation for the mean free path of such particles as a function of the time, which Perrin confirmed experimentally. The fifth paper, A New Determination of Molecular Dimensions , was Einstein's doctoral dissertation, and remains among his most cited articles. It shows how to calculate Avogadro's number and the size of molecules. These papers, presented in a modern English translation, are essential reading for any physicist, mathematician, or astrophysicist. Far more than just a collection of scientific articles, this book presents work that is among the high points of human achievement and marks a watershed in the history of science. Coinciding with the 100th anniversary of the miraculous year, this new paperback edition includes an introduction by John Stachel, which focuses on the personal aspects of Einstein's youth that facilitated and led up to the miraculous year

The range of the essays, as well as their originality, and their critical and historical depth, pay tribute to the extraordinary scope of Professor Cohen's intellectual interests, as a scientist-philosopher and a humanist, and also to his engagement in the world of social and political practice. In Science, Politics and Social Practice, (Volume II of Essays in Honor of Robert S. Cohen), an international group of scholars -- philosophers, sociologists, historians, and political scientists -- discuss issues at the cutting edge of contemporary social and political thought, and its bearing on science. Several essays discuss the relations of Marxism to science, and specifically, to the philosophies of science of Carnap and Popper, as well as Soviet Marxism, and the effects of Stalinism on Soviet science. There are also essays on the philosophy and methodology of the social sciences, on questions of method and aim in historical narrative, on the issue of cultural relativism, and more.
