From his early years as a student in Trinity College, Cambridge, to his studies with Hans Bethe at Cornell University, Freeman Dyson has proven himself to be the best mathematician from England and the best English physicist since Dirac. In the fateful year 1949, Dyson published two ground-breaking papers in the Physical Review, The radiation theories of Tomonaga, Schwinger, and Feynman and The S matrix in quantum electrodynamics. The first demonstrated the equivalence of the Schwinger-Tomonaga approach and the Feynman path integral method in quantum electrodynamics. The second crystalized the Feynman rules for scattering diagrams. Here for the first time, Dyson's lectures at Cornell University shortly after, in 1951, are presented. Brimming with youthful vigour and excitement from the golden years of QED, highly original in their approach, the student is taken for a thrilling ride through the Dirac equation, its manifold consequences, to field theory, the Dyson graphs, and finally to the Feynman diagrams.About the Freeman Dyson is Professor Emeritus at the Institute for Advanced Study in Princeton
Freeman Dyson was a physicist and educator best known for his speculative work on extraterrestrial civilizations and for his work in quantum electrodynamics, solid-state physics, astronomy and nuclear engineering. He theorized several concepts that bear his name, such as Dyson's transform, Dyson tree, Dyson series, and Dyson sphere.
The son of a musician and composer, Dyson was educated at the University of Cambridge. As a teenager he developed a passion for mathematics, but his studies at Cambridge were interrupted in 1943, when he served in the Royal Air Force Bomber Command. He received a B.A. from Cambridge in 1945 and became a research fellow of Trinity College. In 1947 he went to the United States to study physics and spent the next two years at Cornell University, Ithaca, N.Y., and Princeton, where he studied under J. Robert Oppenheimer, then director of the Institute for Advanced Study. Dyson returned to England in 1949 to become a research fellow at the University of Birmingham, but he was appointed professor of physics at Cornell in 1951 and two years later at the Institute for Advanced Study, where he became professor emeritus in 2000. He became a U.S. citizen in 1957.
This book is just way too high level and handwavy for someone trying to get into the deeper aspects of the theory. Physicists at this level have that tendency, and it's truly awful because real deep discussion of mathematics is needed...
