P. A. M. Dirac was one of this century's most outstanding theoretical physicists. Among many fundamental advances, he formulated a fully relativistic theory of the electron, and predicted the existence of the positron. Dirac was awarded the Nobel Prize for Physics in 1933, at the age of just thirty-one. This volume brings together for the first time all of Dirac's scientific publications from 1924 until 1948, his most productive years. Each paper is reproduced in its original form and, for the few not in English, a matching translation is provided. Also included here are reset versions of Dirac's hitherto unpublished wartime research papers. This comprehensive collection will provide a valuable and convenient reference source, and will allow students of the history of science to trace the development of the ideas of one of the founders of quantum mechanics.
This volume reprints Paul Forman's classic papers on the history of the scientific profession in post-World War I Germany and the invention of quantum mechanics. The Forman thesis became famous for its demonstration of the cultural conditioning of scientific knowledge, in particular by showing the historical connection between the culture of Weimar Germany — known for its irrationality and antiscientism — and the emerging concept of quantum acausality. From the moment of its publication, Forman's research provoked intense historical and philosophical debates. In 2007, participants at an international conference in Vancouver, Canada, discussed the implications of the Forman thesis for contemporary historiography. Their contributions collected in this volume represent cutting-edge research on the history of the quantum revolution and of German science.
Ideal for cell biologists, life scientists, biomedical engineers, and clinicians, this handbook provides comprehensive treatment of the theories, techniques, and biomedical applications of nonlinear optics and microscopy.
Cambridge University's Lucasian Professorship of Mathematics is one of the world's most celebrated academic positions. Since its foundation in 1663, the chair has been held by seventeen men who represent some of the most influential minds in science and technology. Principally a social history of mathematics and physics, the story of these great natural philosophers and mathematical physicists is told here by some of the finest historians of science. This informative work offers new perspectives on world famous scientists including Isaac Newton, Charles Babbage, Paul Dirac, and Stephen Hawking.
In a detailed reconstruction of the genesis of Feynman diagrams the author reveals that their development was constantly driven by the attempt to resolve fundamental problems concerning the uninterpretable infinities that arose in quantum as well as classical theories of electrodynamic phenomena. Accordingly, as a comparison with the graphical representations that were in use before Feynman diagrams shows, the resulting theory of quantum electrodynamics, featuring Feynman diagrams, differed significantly from earlier versions of the theory in the way in which the relevant phenomena were conceptualized and modelled. The author traces the development of Feynman diagrams from Feynman's "struggle with the Dirac equation" in unpublished manuscripts to the two of Freeman Dyson's publications which put Feynman diagrams into a field theoretic context. The author brings to the fore that Feynman and Dyson not only created a powerful computational device but, above all, a new conceptual framework in which the uninterpretable infinities that had arisen in the old form of the theory could be precisely identified and subsequently removed in a justifiable manner.
Paul Adrian Maurice Dirac (1902-84) is one of the icons of modern physics. His work provided the mathematical foundations of quantum mechanics. He also made key contributions to quantum field theory and quantum statistical mechanics. He is perhaps best known for formulating the Dirac equation, a relativistic wave equation which described the properties of the electron, and also predicted the existence of anti-matter. The Dirac Centennial Symposium commemorated the contributions of Dirac to all areas of physics, and assessed their impact on frontier research. This book constitutes the proceedings of the symposium, containing articles by Leopold Halpern, Pierre Ramond, Frank Wilczek, Maurice Goldhaber, Jonathan Bagger, Joe Lykken, Roman Jackiw, Stanley Deser, Joe Polchinski, Andre Linde and others. A special contribution from Dirac's daughter Monica Dirac presents a portrait of Paul Dirac as father and family man.
Paul Dirac was among the greatest scientific geniuses of the modern age. One of Einstein's most admired colleagues, he helped discover quantum mechanics, and his prediction of antimatter was one of the greatest triumphs in the history of physics. In 1933 he became the youngest theoretician ever to win the Nobel Prize in Physics. Dirac's personality, like his achievements, is legendary. The Strangest Man uses previously undiscovered archives to reveal the many facets of Dirac's brilliantly original mind.
