Presents the inside story of the creation of the atomic bomb in terms understandable to the layman, and discusses the crisis of conscience following the demonstration of the bomb's destructive effects on Hiroshima.

This biography provides a stimulating and coherent blend of scientific and personal narratives describing the many achievements of the theoretical physicist Herbert Fröhlich. For more than half a century, Fröhlich was an internationally renowned and much respected figure who exerted a decisive influence, often as a 'man ahead of his time', in fields as diverse as meson theory and biology. Although best known for his contributions to the theory of dielectrics and superconductivity, he worked in many other fields, his (...) most important legacy being the pioneering introduction quantum field-theoretical methods into condensed matter physics in 1952, which revolutionised the subsequent development of the subject. Gerard Hyland has written an absorbing and informative account, in which Herbert Fröhlich's magnetic personality shines through. (shrink)

Henri Poincaré was not just one of the most inventive, versatile, and productive mathematicians of all time--he was also a leading physicist who almost won a Nobel Prize for physics and a prominent philosopher of science whose fresh and surprising essays are still in print a century later. The first in-depth and comprehensive look at his many accomplishments, Henri Poincaré explores all the fields that Poincaré touched, the debates sparked by his original investigations, and how his discoveries still contribute to (...) society today. Math historian Jeremy Gray shows that Poincaré's influence was wide-ranging and permanent. His novel interpretation of non-Euclidean geometry challenged contemporary ideas about space, stirred heated discussion, and led to flourishing research. His work in topology began the modern study of the subject, recently highlighted by the successful resolution of the famous Poincaré conjecture. And Poincaré's reformulation of celestial mechanics and discovery of chaotic motion started the modern theory of dynamical systems. In physics, his insights on the Lorentz group preceded Einstein's, and he was the first to indicate that space and time might be fundamentally atomic. Poincaré the public intellectual did not shy away from scientific controversy, and he defended mathematics against the attacks of logicians such as Bertrand Russell, opposed the views of Catholic apologists, and served as an expert witness in probability for the notorious Dreyfus case that polarized France. Richly informed by letters and documents, Henri Poincaré demonstrates how one man's work revolutionized math, science, and the greater world. (shrink)

Michael Eckert has written a remarkable biography of Arnold Sommerfeld , the “off-scale” theoretical physicist who made his Seminar at the University of Munich the outstanding school of theoretical physics of the first third of the twentieth century. Sommerfeld was the teacher and mentor of a large number of exceptional theoretical physicists who studied with him either as doctoral or post-doctoral studentsSee the Wikipedia entry for Arnold Sommerfeld for a complete listing of all his students by category.; and (...) among these, Peter Debye, Max von Laue, Wolfgang Pauli, Werner Heisenberg, Linus Pauling and Hans Bethe became Nobel laureates.In his prologue, Eckert noted that a scientific biography should serve not only as a vehicle to describe and explain scientific processes in a social and cultural context, but must also present “the ambitions, passions, and moral choices of a life in science”. Eckert was able to meet these demands by drawing on Sommerfeld’s personal and .. (shrink)

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 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. In his youth, Julian Schwinger was a nuclear physicist, turning to classical electrodynamics after World War II. In the years after the war, (...) he was the first to renormalize quantum electrodynamics. Subsequently, he presented the most complete formulation of quantum field theory and laid the foundations for the electroweak synthesis of Glashow, Weinberg, and Salam, and he made fundamental contributions to the theory of nuclear magnetic resonance, to many-body theory, and to quantum optics. He developed a unique approach to quantum mechanics, measurement algebra, and a general quantum action principle. His discoveries include 'Feynman's' parameters and 'Glauber's' coherent states; in later years he also developed an alternative to operator field theory which he called Source Theory, reflecting his profound phenomenological bent. His late work on the Thomas-Fermi model of atoms and on the Casimir effect continues to be an inspiration to a new generation of physicists. This biography describes the many strands of his research life, while tracing the personal life of this private and gentle genius. (shrink)

Albert Einstein, among the greatest scientists of all time, was also a man of profound thought and deeply humane feelings. His collected essays offer a fascinating and moving look at one of the twentieth century's leading minds. Covering a fifteen year period from 1934 to 1950, the contents of this book have been drawn from Einstein's articles, addresses, letters and assorted papers. Through his words, you can understand the man and gain his insight on social, religious, and educational issues.

This biography of the famous Soviet physicist Leonid Isaakovich Mandelstam (1889-1944), who became a Professor at Moscow State University in 1925, describes his contributions to both physics and technology, as well as discussing the scientific community which formed around him, usually called the Mandelstam school. Mandelstam's life story is thereby placed in its proper cultural context. The following more general issues are taken under consideration: the impact of German scientific culture on Russian science; the problems and fates of Russian (...) intellectuals during the revolutionary and post-revolutionary years; the formation of the Soviet Academy of Sciences; and transformation of the system of higher education in the USSR during the 1920's and 1930's.The author shows that Mandelstam's fundamental writings and his lectures notes allow to reconstruct his philosophy of science and his approach to the social and ethical functions of science and science education. That reconstruction is enhanced through extensive use of hitherto unpublished archival material as well as the transcripts of personal interviews conducted by the author. (shrink)

The history of physics ranges from antiquity to modern string theory. Since early times, human beings have sought to understand the workings of nature--why unsupported objects drop to the ground, why different materials have different properties, and so forth. The emergence of physics as a science, distinct from natural philosophy, began with the scientific revolution of the 16th and 17th centuries when the scientific method came into vogue. Speculation was no longer acceptable; research was required. The beginning of the 20th (...) century marks the start of a more modern physics. Physicists began to study the atom, with its electrons and its nucleus. Then they began to look at the fundamental question of the forces that hold the nucleus together and the particles that account for the natural forces. This book approaches the history of physics from a biographical point of view, considering people to be more interesting than things, and the combination of the two more interesting than the sum of the individual parts. After a brief overview of classical and modern physics, 336 one-page biographies of individuals who have made significant contributions to the field of physics are presented. (shrink)

This biography sheds new light on the life and work of physicist Ettore Majorana (including unpublished contributions), as well as on his mysterious disappearance in March 1938. Majorana is held by many, including Nobel Laureate, Enrico Fermi, to have been a genius of the rank of Galilei and Newton. In this intriguing story, the author, himself a leading expert on the work of Majorana, supplements the existing literature with new insights, anecdotes and personal accounts of contemporaries of Majorana.

The career of the German physicist Walther Gerlach (1889–1979) spanned two world wars and the changing political systems in Germany in the twentieth century. As a physicist involved in the rapid development of atomic physics and the management of scientific research in Germany during World War II as well as in post-war West Germany, several attempts have been made in the past by historians of science to write his full biography. These projects have, among other foci, asked about Gerlach's (...) role and his position with respect to National Socialism. However, based on his extensive papers preserved in the Deutsches Museum Archive in Munich, none of these projects has so far been conclusive. In this article, we identify evidence for the selective deletion of personal files relating to his first wife and daughter. We argue that reconstructing this lacuna sheds new light on the influence of National Socialist ideology on Gerlach's personal life, making him both a profiteer and a victim of eugenics jurisdiction.

The extraordinary career of the British Quaker polymath, Silvanus Phillips Thompson (1851–1916), encompassed fame in physics, electrical engineering, mathematics, history of science, educational method, painting, music, textbooks, X-rays, popular lectures, the promotion of women's rights, book-collecting, and not least his leadership in encouraging fellow Quakers to embrace the challenging results of research in the natural sciences. His public-facing career, with a reputation that ranged across Western Europe at least, centred on the sincere yet critical communication of new technical and historical (...) knowledge, in a mastery of four languages. Yet his kaleidoscopic work has not received any sustained historical examination since the Life and Letters produced by his widow Jane and daughter Helen in 1920. The centenary of his death was marked by an interdisciplinary workshop at the Westminster (Quaker) Meeting-House, “‘A Many-sided Crystal’: The Quaker Physicist and Electrical Engineer Silvanus Phillips Thompson” on September 16, 2016. This spotlight section of Centaurus captures four of the revised contributions to that event, and these cover Thompson's contributions to historical theory, biographical practice, and commercial technology, as just a few elements of the rich and complex legacy that emerged posthumously from his multifarious, polymathic talents. These collectively point us to a revised view of Thompson as a pre-First World War European figure who gained his authority not from specialization in a single area of esoteric research, but from a life of public service that integrated the literary arts and historical writing with sciences and engineering, all incorporated within an active Quaker practice. The papers in this collection thus show how Thompson came to be an historian of science with an unprecedented mastery of contemporaneous techno-scientific arts and sophisticated skills in historical-biographical writing, working harmoniously in a secular world with a rigorous yet non-dogmatic faith.

Using an original approach, Mauro Dardo recounts the major achievements of twentieth-century physics--including relativity, quantum mechanics, atomic and nuclear physics, the invention of the transistor and the laser, superconductivity, binary pulsars, and the Bose-Einstein condensate--as each emerged. His year-by-year chronicle, biographies and revealing personal anecdotes help bring to life the main events since the first Nobel Prize was awarded in 1901. The work of the most famous physicists of the twentieth century--including the Curies, Bohr, Heisenberg, Einstein, Fermi, Feynman, Gell-Mann, (...) Rutherford, and Schrödinger--is presented, often in the words and imagery of the prize-winners themselves. Mauro Dardo is Professor of Experimental Physics at Amedeo Avogadro University. He has served as Dean of the new Faculty of Sciences at the University of Turin in Alessandria, Piedmont, and has also served as Director of the university's new department of Sciences and Advanced Technologies.

Although quantum physics is considered the soundest physical theory, its strange and paradoxical features have challenged - and continue to challenge - even the brightest thinkers. David Bohm dedicated his entire life to enhancing our understanding of quantum mysteries, in particular quantum nonlocality. His work took place at the height of the cultural/political upheaval in the 1950's, which led him to become the most notable American (...) scientist to seek exile in the last century.

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments (...) against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work. (shrink)

Abraham Pais's Subtle Is the Lord was a publishing phenomenon: a mathematically sophisticated exposition of the science and the life of Albert Einstein that reached a huge audience and won an American Book Award. Reviewers hailed the book as "a monument to sound scholarship and graceful style", "an extraordinary biography of an extraordinary man", and "a fine book". In this groundbreaking new volume, Pais undertakes a history of the physics of matter and of physical forces since the discovery of (...) x-rays. The book attempts to relate not only what has happened over the last hundred years but why it happened the way it did, what it was like for those scientists involved, and how what at the time may have seemed a series of bizarre or unrelated events, now with hindsight emerges as a logical sequence of events. Pais, a noted physicist, was personally involved in many of the developments he describes, and thus Inward Bound, like his earlier book, is filled with unique insights into the world of big and small physics. Between 1895 and 1983, the period he covers, the smallest distances explored have shrunk a hundred millionfold, Pais notes. Along this incompletely traveled "road inward," scientists have established markers that later generations will rank among the principal monuments of the twentieth century. In alternating technical and nontechnical sections, this magisterial survey richly conveys what has been discovered about the constituents of matter, the laws to which they are subject, and the forces that act on them. But the advances have certainly not come smoothly. The book shows that these have been times of progress and stagnation, of order and chaos, of clarity and confusion, of belief and incredulity, of the conventional and the bizarre; also of revolutionaries and conservatives, of science by individuals and by consortia, of little gadgets and big machines, and of modest funds and big money. About the Author: Abraham Pais is Detlev W. Bronk Professor of Physics at the Rockefeller University. The author of the prizewinning biography of Einstein now undertakes a history of modern physics.

François Arago, the first to show in 1810 that the surface of the Sun and stars is made of incandescent gas and not solid or liquid, was a prominent physicist of the 19th century. He used his considerable influence to help Fresnel, Ampere and others develop their ideas and make themselves known. This book covers his personal contributions to physics, astronomy, geodesy and oceanography, which are far from negligible, but insufficiently known. Arago was also an important and influential political man (...) who, for example, abolished slavery in the French colonies. One of the last humanists, he had a very broad culture and range of interests. In parallel to his biography, this title also covers the spectacular progresses of science at the time of Arago, especially in France: the birth of physical optics, electromagnetism and thermodynamics. Francois Arago's life is a fascinating epic tale that reads as a novel. (shrink)

An homage to the men and women of science, and an exposition of Einstein's place in scientific history In this fascinating collection of articles and speeches, Albert Einstein reflects not only on the scientific method at work in his own theoretical discoveries, but also eloquently expresses a great appreciation for his scientific contemporaries and forefathers, including Johannes Kepler, Isaac Newton, James Clerk Maxwell, Max Planck, and Niels Bohr. While Einstein is renowned as one of the foremost innovators of modern science, (...) his discoveries uniquely his own, through his own words it becomes clear that he viewed himself as only the most recent in a long line of scientists driven to create new ways of understanding the world and to prove their scientific theories. Einstein's thoughtful examinations explain the "how" of scientific innovations both in his own theoretical work and in the scientific method established by those who came before him. This authorized Philosophical Library book features a new introduction by Neil Berger, PhD, and an illustrated biography of Albert Einstein, which includes rare photos and never-before-seen documents from the Albert Einstein Archives at the Hebrew University of Jerusalem. "What place does the theoretical physicist's picture of the world occupy among all these possible pictures? It demands the highest possible standard of rigorous precision in the description of relations, such as only the use of mathematical language can give" -Albert Einstein, "Principles of Research" Albert Einstein (1879-1955) was born in Germany and became an American citizen in 1934. A world-famous theoretical physicist, he was awarded the 1921 Nobel Prize for Physics and is renowned for his Theory of Relativity. In addition to his scientific work, Einstein was an influential humanist who spoke widely about politics, ethics, and social causes. After leaving Europe, Einstein taught at Princeton University. His theories were instrumental in shaping the atomic age. Neil Berger, an associate professor emeritus of mathematics, taught at the University of Illinois at Chicago in the Mathematics, Statistics, and Computer Science department from 1968 until his retirement in 2001. He was the recipient of the first Monroe H.

He has published numerous papers and reviews in his fields of expertise, which include elasticity, tensor analysis, scattering theory, and fluid mechanics. (shrink)

As Einstein’s successor in Prague and the author of a biography on Einstein, the physicist and philosopher Philipp Frank made relativity a central aspect of his thoughts on morality. He published his views on this topic mainly in the year 1950 in a small book entitled Relativity—A Richer Truth. As far as morality as a part of social and political life is concerned, Frank’s primary interest is to show that as in science, relativity in morality does not preclude objectivity. (...) The paper deals with the question of which conceptions of relativity and relativism Frank refers to in the context of modern science and examines the implications for objectivity and absolute values in morality.

Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, and humane a mind; and furthermore he went further, (...) as I soon realized when I looked for his name on other publications. I recall arguing with myself over his exploration of 'Indeterminacy and Economic Development' (1948), and even more when I read his 'Dialectical Materialism and Soviet Science' (1949). More papers, and then the fascinating, sometimes irritating, always insightful, books. His monograph on Psychoanalysis and Ethics 1955, the beautiful sociological and humanist study of Spinoza and the Rise of Liberalism (1958), his essays on 'The Social Roots of Einstein's Theory of Relativity' (1971) together with the book on Einstein and the Genera tions of Science (1974), the splendid reader from the works of Marx and Engels, Basic Writings on Politics and Philosophy (1959) which was a major text of the '60s, the stimulating essays on the social formation which seems to have been required for a modern scientific movement to develop, set forth most convincingly in The Scientific Intellectual (1963).

After a short sketch of the biography of Nicolaus Copernicus, the great astronomer's conception of God is analysed according to the original introduction into the first book of De revolutionibus and the dedicatory epistle to Pope Paul III. For Copernicus as for many ancient philosophers the sky is the visible God; therefore the study of the movement of the celestial bodies is the most excellent way to the invisible God. The Creator is the great architect of all things; in (...) the cognition of the mathematically simple structure of the universe man will become united with Him. It is suggested that these theological ideas gave Copernicus the pertinacy to work out his heliocentric system despite the misgivings of the contemporary Aristotelian physicists. (shrink)

O objectivo primário do presente artigo é estudar algumas das implicações, sobretudo epistemológicas, associadas com o auto-intitulado movimento da Física Ariana (Deutsche Physikj, movimento esse que aqui se considera como tendo sido iniciado pelos físicos, laureados com o Prémio Nobel, Philipp Lenard e Johannes Stark. Assim, em primeiro lugar, procura-se analisar questões como a da ligação entre ciência e raça, a da função do método experimental e do método dedutivo nas descobertas das ciências naturais, bem como a da relação entre (...) matemática e natureza, já para não mencionar a dimensão histórica da ciência. Em vez de recorrer a conceitos supostamente puros do que sejam ciência ou racionalidade em ordem a instaurar um tribunal da história, cujo veredicto seria a condenação da Física Ariana como irrisória anomalia epistemológica no corpo histórico da ciência, os autores do presente artigo procuram, antes de mais, traçar a origem do movimento a partir das biografias de Lenard e Stark, acreditando que o carácter profundamente conturbado de ambos, coadunado com a conflituosa situação política que antecedeu a ascensão de Hitler ao poder na Alemanha em 1933, seriam razões suficientes para a formação das doutrinas que atacavam a Física Teórica. Nesse sentido, depois de expor os princípios e as ideias defendidas pelos físicos arianos, os autores procuram evidenciar até que ponto uma análise restrita ao campo da física e dos seus documentos não é suficiente para uma compreensão cabal de tal movimento. Ao mesmo tempo, procuram mostrar também por que razão é necessário considerar que algumas objecções levantadas contra a física teórica se constituíam como problemas verdadeiramente relevantes, sendo que alguns deles foram também formulados por autores que não pactuavam com as convicções políticas de Lenard e Stark. Finalmente, o artigo comporta uma análise das posições defendidas por Werner Heisenberg em ordem a mostrar a seriedade com a qual as críticas dos físicos arianos foram recebidas por este autor, nelas reconhecendo algo digno de ser respondido, e isso não meramente por razões políticas, mas antes porque constituíam dilemas reais instalados na prática das ciências naturais. Ou seja, recorrendo aos argumentos esgrimidos por Werner Heisenberg, os autores do artigo pretendem demonstrar que a Física Ariana não merece atenção apenas na sua qualidade de aberração histórica, mas também pelo facto de ela ter levantado questões ainda hoje epistemologicamente relevantes. /// The primary aim of the present article is to study some of the implications, particularly the epistemological ones, associated with the movement of the so called German Physics (Deutsche PhysikJ, a movement that in this article is mainly associated with the work of the physicists, and Nobel laureates, Phillip Lenard and Johannes Stark. The article begins by analyzing questions related to the connection established between science and race, as well as to the function of the experimental and deductive methods in the discoveries of the natural sciences, not to mention the problems associated with the relation between mathematics and nature as well as the historical dimension of science. The goal, therefore, is not to take supposedly pure concepts about what science and rationality might be and establish them as judges in the tribunal of history, whose verdict would be the condemnation of the German Physics as an insignificant epistemological anomaly within the historical body of science. Rather, the authors of the article want to trace the origin of the movement of the German Physics by reading the biographies of Lenard and Stark, whereby it is assumed that the problematic character of these physicists together with the political situation that anteceded Hitlers ascension to power in Germany in 1933 would be reason enough for the formation of doctrines directed against theoretical physics. In this sense, after expounding the principles and the doctrines defended by the Arian physicists, the authors of the article show that an analysis circumscribed to the domain of physics would not be sufficient for a global understanding of this movement. At the same time, however, the authors also want to show the reason why it is necessary to consider some of the objections raised against theoretical physics as serious problems, even though some of them were also formulated by authors that did not share the political convictions of Lenard and Stark. Finally, the article contains an analysis of the positions defended by Werner Heisenberg in order to demonstrate the seriousness with which the criticisms of the Arian physicists were received by this most important author, so much so that he recognized in them something worth a response, and this not only for political reasons, but also because he recognized the problems raised as a dilemma situated at the very heart of the practice of the natural sciences. In other words, by a close reading of the arguments presented by Werner Heisenberg, the authors of the article want to demonstrate that the movement of German Physics is worth attention not only in its quality as an historical aberration, but also due to the fact that it raised questions that are still epistemologically relevant.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Dictionary of Eighteenth-Century British PhilosophersHeiner F. KlemmeJohn W. Yolton, John Valdimir Price, John Stephens, general editors. The Dictionary of Eighteenth-Century British Philosophers. Vols. 1, 2. Bristol: Thoemmes Press, 1999. Pp. xxiii + 1,013. Cloth, $550.00.Good dictionaries are like good maps of a city: they indicate the main and minor quarters, give you an impression of its internal developments, and they indicate to where its highways eventually lead. (...) In philosophy, comprehensive subject dictionaries have a long history, and they do seem to experience a revival these days. To be sure, the lives and works of the leading figures of the history of ideas are generally well explored and documented. We even know which French dishes Hume liked to cook or which types of wine Kant preferred. But the lives and works of lesser known philosophers and men of letters still seem to be more or less neglected. The Dictionary of Eighteenth-Century British Philosophers fills this gap for the period and the subject it covers. It comprises entries on almost six hundred persons as well as a number of entries on anonymous works. The work of close to a hundred scholars from several countries, it is unique in its attempt to bring together in two extensive volumes all minor and major British philosophers of the period between John Locke and Dugald Stewart. Since "British" is to be understood in a broad sense meaning authors who lived under British rule, it also includes Americans writing before 1776, Irish philosophers (like George Berkeley) and the French thinker Pierre Desmaizeaux, who lived and worked for a long period in Britain. Nor is the Dictionary restricted to philosophers in today's sense of the word, comprising entries on people who made in one way or the other a contribution to the history of ideas, even if their contributions are of marginal importance. Besides historians, poets, translators, mathematicians and physicists, dissenting ministers and physicians are well represented.In almost all cases, the selection makes sense. The boundaries between philosophy and, say, natural sciences were not as nicely drawn in the eighteenth century as they are today. But there are a few entries where one might wonder whether the subject's work had any specific philosophical importance or influence at all, as for example: Charles Burnet, author of a history of music; John Ellicott, who wrote on Electricity, and Thomas Innes, who published in 1729 a book on "Ancient Inhabitants on the Northern Parts of Britain or Scotland." One might also wonder if Gaelic scholar Beg Eolach Moidhach would appreciate being remembered today as a British philosopher.The length of the entries varies from several lines to up to seven pages. Generally, each entry gives the details of the life and work of the person covered, provides a bibliography of his or her main works, references to "other relevant works," and a section of "further reading." While the larger entries are naturally devoted to the better known figures, most of the authors dealt with in the minor sections cannot complain either. In many cases, information about the life and work of these minor authors is scarce and the entries are useful for this reason alone. But unfortunately, there are also cases in which essential references to "classical" biographical accounts are not listed in the bibliography, like Williams Smellie´s account of James Gregory or George Skene Keith´s biography of John Campbell.The entries on Lord Kames and George Turnbull lay, as far as their length is [End Page 282] concerned, somewhere in the middle between the shorter and longer contributions. They nevertheless are highly informative, densely argued, and are good reading.
