Book excerpt: It is now a little more than 11 years since the idea of writing a personal and scientific biography of H. A. Kramers took hold of me. A few days earlier I had been lecturing, in a course on field theory, on the renormalization proce dures of relativistic quantum field theory. Since the students had considerable trouble understanding the physical basis of the procedure, at the end of the lecture T explained that renormalization is not an exclusive quantum or relativistic procedure. A careful treatment of classical electron theory as started by Lorentz and developed in detail by Kramers also requires re normalization. The students appeared quite interested and I promised them that I would explain all this in more detail in the next lecture. I could have looked up this material in Kramers' book, but I remembered that Kramers had stressed this idea in a course I had attended in Leiden in 1938-1939. I did dig up some of these old notes and, although they were considerably less transparent than my recollection seemed to indicate, they reminded me force fully of the thrilling days I had spent in Leiden with Kramers. Kramers' deep insight and originality were apparent even when distorted by my opaque notes. The students had never heard of these ideas of Kramers' and were totally unaware of his work in field theory.

Download or read book Quantum Reality Relativistic Causality and Closing the Epistemic Circle written by Wayne C. Myrvold and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 2006, a major international conference was held at the Perimeter Institute for Theoretical Physics, Canada, to celebrate the career and work of a remarkable man of letters. Abner Shimony, who is well known for his pioneering contributions to foundations of quantum mechanics, is a physicist as well as a philosopher, and is highly respected among the intellectuals of both communities. In line with Shimony’s conviction that philosophical investigation is not to be divorced from theoretical and empirical work in the sciences, the conference brought together leading theoretical physicists, experimentalists, as well as philosophers. This book collects twenty-three original essays stemming from the conference, on topics including history and methodology of science, Bell's theorem, probability theory, the uncertainty principle, stochastic modifications of quantum mechanics, and relativity theory. It ends with a transcript of a fascinating discussion between Lee Smolin and Shimony, ranging over the entire spectrum of Shimony's wide-ranging contributions to philosophy, science, and philosophy of science.
Download or read book Nico Bloembergen written by Rob Herber and published by Springer Nature. This book was released on 2019-11-25 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This biography is a personal portrait of one of the best-known Dutch physicists, Nicolaas Bloembergen. Born in 1920 in Dordrecht, Bloembergen studied physics in Utrecht, leaving after World War II for the United States, where he became an American citizen in 1958. At Harvard University, he pioneered nuclear magnetic resonance (NMR, used in chemistry and biology for structure identification; moreover leading to MRI), laser theory and nonlinear optics. In 1978 he was awarded the Lorentz Medal for his contribution to the theory of nonlinear optics (used in fiber optics), and in 1981 he received the Nobel Prize for physics, along with Arthur Schawlow and Kai Siegbahn. The book is based on numerous conversations with Nicolaas Bloembergen himself, his wife Deli Brink, his family, and colleagues in science. It describes his childhood and study in Bilthoven and Utrecht, the first postwar years at Harvard, the discoveries of masers and lasers, and the award of the Nobel Prize. It also delves into Bloembergen's involvement in American politics, particularly his role in Ronald Reagan's controversial "Star Wars" program.
Download or read book L on Rosenfeld written by Anja Skaar Jacobsen and published by World Scientific. This book was released on 2012 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Léon Rosenfeld (1904-1974) was a remarkable, many-sided physicist of exceptional erudition. He was at the center of modern physics and was well-known as Niels Bohr's close collaborator and spokesman. Besides he reflected deeply on the history and philosophy of science and its social role from a leftist perspective. As both actor and acute spectator of modern physics and as a polyglot cosmopolitan whose life crossed those of many important people in both the East and West, as well as by virtue of his close collaboration and friendship with Bohr, Rosenfeld was an important figure in twentieth century physics. His biography illuminates the development, popularization, and reception of quantum physics and its interpretation in addition to the development of the political Left. The book draws extensively from previously untapped, unpublished sources in more than five languages.
Download or read book The Making of Modern Physics in Colonial India written by Somaditya Banerjee and published by Routledge. This book was released on 2020-05-14 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph offers a cultural history of the development of physics in India during the first half of the twentieth century, focusing on Indian physicists Satyendranath Bose (1894-1974), Chandrasekhara Venkata Raman (1888-1970) and Meghnad Saha (1893-1956). The analytical category "bhadralok physics" is introduced to explore how it became possible for a highly successful brand of modern science to develop in a country that was still under colonial domination. The term Bhadralok refers to the then emerging group of native intelligentsia, who were identified by academic pursuits and manners. Exploring the forms of life of this social group allows a better understanding of the specific character of Indian modernity that, as exemplified by the work of bhadralok physicists, combined modern science with indigenous knowledge in an original program of scientific research. The three scientists achieved the most significant scientific successes in the new revolutionary field of quantum physics, with such internationally recognized accomplishments as the Saha ionization equation (1921), the famous Bose-Einstein statistics (1924), and the Raman Effect (1928), the latter discovery having led to the first ever Nobel Prize awarded to a scientist from Asia. This book analyzes the responses by Indian scientists to the radical concept of the light quantum, and their further development of this approach outside the purview of European authorities. The outlook of bhadralok physicists is characterized here as "cosmopolitan nationalism," which allows us to analyze how the group pursued modern science in conjunction with, and as an instrument of Indian national liberation.

Download or read book The Quantum Vacuum written by Peter W. Milonni and published by Academic Press. This book was released on 2013-10-22 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern physics, the classical vacuum of tranquil nothingness has been replaced by a quantum vacuum with fluctuations of measurable consequence. In The Quantum Vacuum, Peter Milonni describes the concept of the vacuum in quantum physics with an emphasis on quantum electrodynamics. He elucidates in depth and detail the role of the vacuum electromagnetic field in spontaneous emission, the Lamb shift, van der Waals, and Casimir forces, and a variety of other phenomena, some of which are of technological as well as purely scientific importance. This informative text also provides an introduction based on fundamental vacuum processes to the ideas of relativistic quantum electrodynamics and quantum field theory, including renormalization and Feynman diagrams. Experimental as well as theoreticalaspects of the quantum vacuum are described, and in most cases details of mathematical derivations are included. Chapter 1 of The Quantum Vacuum - published in advance in The American Journal of Physics (1991)-was later selected by readers as one of the Most Memorable papers ever published in the 60-year history of the journal. This chapter provides anexcellent beginning of the book, introducing a wealth of information of historical interest, the results of which are carefully woven into subsequent chapters to form a coherent whole. - Does not assume that the reader has taken advanced graduate courses, making the text accessible to beginning graduate students - Emphasizes the basic physical ideas rather than the formal, mathematical aspects of the subject - Provides a careful and thorough treatment of Casimir and van der Waals forces at a level of detail not found in any other book on this topic - Clearly presents mathematical derivations
Download or read book Photons written by Klaus Hentschel and published by Springer. This book was released on 2018-08-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the gradual formation of the concept of ‘light quanta’ or ‘photons’, as they have usually been called in English since 1926. The great number of synonyms that have been used by physicists to denote this concept indicates that there are many different mental models of what ‘light quanta’ are: simply finite, ‘quantized packages of energy’ or ‘bullets of light’? ‘Atoms of light’ or ‘molecules of light’? ‘Light corpuscles’ or ‘quantized waves’? Singularities of the field or spatially extended structures able to interfere? ‘Photons’ in G.N. Lewis’s sense, or as defined by QED, i.e. virtual exchange particles transmitting the electromagnetic force? The term ‘light quantum’ made its first appearance in Albert Einstein’s 1905 paper on a “heuristic point of view” to cope with the photoelectric effect and other forms of interaction of light and matter, but the mental model associated with it has a rich history both before and after 1905. Some of its semantic layers go as far back as Newton and Kepler, some are only fully expressed several decades later, while others initially increased in importance then diminished and finally vanished. In conjunction with these various terms, several mental models of light quanta were developed—six of them are explored more closely in this book. It discusses two historiographic approaches to the problem of concept formation: (a) the author’s own model of conceptual development as a series of semantic accretions and (b) Mark Turner’s model of ‘conceptual blending’. Both of these models are shown to be useful and should be explored further. This is the first historiographically sophisticated history of the fully fledged concept and all of its twelve semantic layers. It systematically combines the history of science with the history of terms and a philosophically inspired history of ideas in conjunction with insights from cognitive science.

This book was released on 2011-06-28 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2) the globalization of capital has far outstripped the ability of current labor movements, organized at best on a national level, to conduct an effective defense of the interests of labor within capitalism, let alone to seriously challenge the cap italist system. To develop some form-or forms--of international organization of labor, long an ideological challenge ("Workers of the World Unite") has now become an urgent matter of survival for the labor movements of the world. Here is a challenge, on which I think broad agreement is possible: Even those who think capitalism is capable of indefinite survival must agree that it has functioned best in the past-for example, during the long period of post-World War II expansion when the power of capital has been effectively limited by the countervailing power of labor. Effective exercise of that power has always depended on overcoming the seg mentation of labor due to such factors as locality, race, gender, occupation, etc. , which stilIremain important. Above, I have singled out the two factors that today seem key to me: the split between mental and manual labor, and segmentation by nationality. Let all concerned about the current state of capitalism work to build up the countervailing power of labor, and let time show whether this results in nothing more than the better functioning of capitalism, or whether a new challenge to the system ultimately emerges.
Download or read book The Quantum Ten written by Sheilla Jones and published by Dundurn. This book was released on 2014-03-31 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical physics is in trouble. At least that’s the impression you’d get from reading a spate of recent books on the continued failure to resolve the 80-year-old problem of unifying the classical and quantum worlds. The seeds of this problem were sewn eighty years ago when a dramatic revolution in physics reached a climax at the 1927 Solvay conference in Brussels. It’s the story of a rush to formalize quantum physics, the work of just a handful of men fired by ambition, philosophical conflicts and personal agendas. Sheilla Jones paints an intimate portrait of the ten key figures who wrestled with the mysteries of the new science of the quantum, along with a powerful supporting cast of famous (and not so famous) colleagues. The Brussels conference was the first time so many of the “quantum ten” had been in the same place: Albert Einstein, the lone wolf; Niels Bohr, the obsessive but gentlemanly father figure; Max Born, the anxious hypochondriac; Werner Heisenberg, the intensely ambitious one; Wolfgang Pauli, the sharp-tongued critic with a dark side; Paul Dirac, the silent Englishman; Erwin Schrödinger, the enthusiastic womanizer; Prince Louis de Broglie, the French aristocrat; Pascual Jordan, the ardent Aryan nationalist, who was not invited; and Paul Ehrenfest, who was witness to it all. This is the story of quantum physics that has never been told, an equation-free investigation into the turbulent development of the new science and its very fallible creators, including little-known details of the personal relationship between the deeply troubled Ehrenfest and his dear friend Albert Einstein. Jones weaves together the personal and the scientific in a heartwarming—and heartbreaking—story of the men who struggled to create quantum physics ... a story of passion, tragedy, ambition and science.
Download or read book Quantum Generations written by Helge Kragh and published by Princeton University Press. This book was released on 2020-06-16 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the end of the nineteenth century, some physicists believed that the basic principles underlying their subject were already known, and that physics in the future would only consist of filling in the details. They could hardly have been more wrong. The past century has seen the rise of quantum mechanics, relativity, cosmology, particle physics, and solid-state physics, among other fields. These subjects have fundamentally changed our understanding of space, time, and matter. They have also transformed daily life, inspiring a technological revolution that has included the development of radio, television, lasers, nuclear power, and computers. In Quantum Generations, Helge Kragh, one of the world's leading historians of physics, presents a sweeping account of these extraordinary achievements of the past one hundred years. The first comprehensive one-volume history of twentieth-century physics, the book takes us from the discovery of X rays in the mid-1890s to superstring theory in the 1990s. Unlike most previous histories of physics, written either from a scientific perspective or from a social and institutional perspective, Quantum Generations combines both approaches. Kragh writes about pure science with the expertise of a trained physicist, while keeping the content accessible to nonspecialists and paying careful attention to practical uses of science, ranging from compact disks to bombs. As a historian, Kragh skillfully outlines the social and economic contexts that have shaped the field in the twentieth century. He writes, for example, about the impact of the two world wars, the fate of physics under Hitler, Mussolini, and Stalin, the role of military research, the emerging leadership of the United States, and the backlash against science that began in the 1960s. He also shows how the revolutionary discoveries of scientists ranging from Einstein, Planck, and Bohr to Stephen Hawking have been built on the great traditions of earlier centuries. Combining a mastery of detail with a sure sense of the broad contours of historical change, Kragh has written a fitting tribute to the scientists who have played such a decisive role in the making of the modern world.
Download or read book Drawing Theories Apart written by David Kaiser and published by University of Chicago Press. This book was released on 2009-11-15 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2007 Pfizer Prize from the History of Science Society. Feynman diagrams have revolutionized nearly every aspect of theoretical physics since the middle of the twentieth century. Introduced by the American physicist Richard Feynman (1918-88) soon after World War II as a means of simplifying lengthy calculations in quantum electrodynamics, they soon gained adherents in many branches of the discipline. Yet as new physicists adopted the tiny line drawings, they also adapted the diagrams and introduced their own interpretations. Drawing Theories Apart traces how generations of young theorists learned to frame their research in terms of the diagrams—and how both the diagrams and their users were molded in the process. Drawing on rich archival materials, interviews, and more than five hundred scientific articles from the period, Drawing Theories Apart uses the Feynman diagrams as a means to explore the development of American postwar physics. By focusing on the ways young physicists learned new calculational skills, David Kaiser frames his story around the crafting and stabilizing of the basic tools in the physicist's kit—thus offering the first book to follow the diagrams once they left Feynman's hands and entered the physics vernacular.
