Abstract

Interview covers the development of several branches of theoretical physics from the 1930s through the 1960s; the most extensive discussions deal with topics in quantum electrodynamics, nuclear physics as it relates to fission technology, meson field theory, superfluidity and other properties of liquid helium, beta decay and the Universal Fermi Interaction, with particular emphasis on Feynman's work in the reformulation of quantum electrodynamic field equations. Early life in Brooklyn, New York; high school; undergraduate studies at Massachusetts Institute of Technology; learning the theory of relativity and quantum mechanics on his own. To Princeton University (John A. Wheeler), 1939; serious preoccupation with problem of self-energy of electron and other problems of quantum field theory; work on uranium isotope separation; Ph.D., 1942. Atomic bomb project, Los Alamos (Hans Bethe, Niels Bohr, Enrico Fermi); test explosion at Alamagordo. After World War II teaches mathematical physics at Cornell University; fundamental ideas in quantum electrodynamics crystalize; publishes "A Space-Time View," 1948; Shelter Island Conference (Lamb shift); Poconos Conferences; relations with Julian Schwinger and Shin'ichiro Tomonaga; nature and quality of scientific education in Latin America; industry and science policies. To California Institute of Technology, 1951; problems associated with the nature of superfluid helium; work on the Lamb shift (Bethe, Michel Baranger); work on the law of beta decay and violation of parity (Murray Gell-Mann); biological studies; philosophy of scientific discovery; Geneva Conference on the Peaceful Uses of Atomic Energy; masers (Robert Hellwarth, Frank Lee Vernon, Jr.), 1957; Solvay Conference, 1961. Appraisal of current state of quantum electrodynamics; opinion of the National Academy of Science; Nobel Prize, 1965.

Abstract

Involvement in the history of quantum physics and nuclear physics; thoughts on physics institutions in underdeveloped countries. Studies at University of Vienna in the early 1920s; his work at Felix Ehrenhaft's Institute until 1928; subsequent assistantship with Werner Heisenberg at University of Leipzig for four years. Conversations with Heisenberg about electrons in the nucleus; origins of Beck's interest in nuclear physics after hearing Francis W. Ashton's paper on mass defect at the 1927 Volta Conference; conferences at University of Copenhagen including 1932, where, before the positron was discovered, everyone was making fun of Paul A. M. Dirac's "holes." Theory of beta decay, inability to continue work on it due to lack of additional data when going to Kansas in 1934 and Odessa in 1935. Leaves Odessa; internment in France during the war; escape to Portugal and arrives in Argentina. Also prominently mentioned are: M. Besso, Niels Bohr, Albert Einstein, Wolfgang Pauli, Ernest Rutherford, Erwin Schrodinger, Adolf Smekal, Hans Thirring, Joseph J. Thomson, Victor F. Weisskopf, and Hideki Yukawa.
