Signed by Pais. . / BIOGRAPHY: Tomonaga was a prominent Japanese physicist influential in the development of quantum electrodynamics work for which he was jointly awarded the 1965 Nobel Prize in Physics :: along with Richard Feynman and Julian Schwinger :: for the study of QED specifically for the discovery of the renormalization method. Nobel biography: Tomonaga completed work for Rigakushi bachelor's degree in physics at Kyoto Imperial University in 1929 with one of his intimate friends. Dr. Hideki Yukawa Nobel laureate. He was engaged in graduate work for three years at the same university and was then appointed a research associate by Dr. Yoshio Nishina at the Institute of Physical and Chemical Research Tokyo where he started to work in a newly developed frontier of theoretical physics quantum electrodynamics - under the guidance of Dr. Nishina. His paper on the photoelectric pair creation is well-known. Tomonaga stayed in Leipzig Germany from 1937 to 1939 to study nuclear physics and the quantum field theory in collaboration with the theoretical group of Dr. W. Heisenberg where he published a paper "Innere Reibung und Warmeleitfahigkeit der Kernmaterie" which was chosen as the thesis for Rigakuhakushi Doctor of Science at Tokyo Imperial University in December1939. In 1940 Dr. Tomonaga directed his attention to the meson theory and developed the intermediate coupling theory in order to clarify the structure of the meson cloud around the nucleon. He joined the faculty of Tokyo Bunrika University which was absorbed into the Tokyo University of Education in 1949 as Professor of Physics in 1941. It was in 1942 when he first proposed the covariant formulation of the quantum field theory in which the concept of the quantum state was generalized so as to be relativistically covariant. During the Second World War Dr. Tomonaga was interested in developing a theory of microwave systems. He solved the motion of electrons in the magnetron and also developed a unified theory of the systems consisting of wave guides and cavity resonators. As soon as the War was over Tomonaga came back to academic research again with a programme in which he was first to summarize and extend the intermediate coupling theory and secondly to apply the covariant field theory to actual physical systems. His aim was to investigate the nature of field reaction in the meson theory as well as in quantum electrodynamics. He was confident prior to the Lamb-Retherford experiment by means of a model calculation that divergence difficulty in quantumelectrodynamics could be overcome simply by handling the infinite mass and charge due to field reactions in some way or another. It was only a step further for him to develop the renormalization theory with covariant formalism in his right hand and experimental support in his left. Dr. Tomonaga was invited to the Institute for Advanced Study Princeton in 1949 where he was engaged in the investigation of a one-dimensional fermion system. Thus he first succeeded in clarifying the nature of collective oscillations of a quantum-mechanical many-body system and opened a new frontier of theoretical physics modern many-body problem. In 1955 he published an elementary theory of quantum mechanical collective motions. Dr. Tomonaga took the leadership in establishing the Institute for Nuclear Study University of Tokyo in 1955. From 1956 to 1962 he was appointed President of the Tokyo University of Education and since 1963 he has been President of the Science Council of Japan and Director of the Institute for Optical Research Tokyo University of Education. He occupies an important position in various governmental committees for scientific research and policymaking. Tomonaga's honours and awards include the Japan Academy Prize 1948; the Order of Culture 1952; the Lomonosov Medal U.S.S.R. 1964. Dr. Tomonaga is a member of the Japan Academy the Deutsche Akademie der Naturforscher "Leopoldina" and a foreign member of the Royal Swedish Academy of Science. He is a corresponding member of the Bayerische Akademie der Wissenschaften and a foreign associate of the National Academy of Science of U.S.A. Tomonaga has published widely in scientific journals on such subjects as quantum electrodynamics the meson theory nuclear physics cosmic rays and the many-body problem. His book "Quantum Mechanics" was published in 1949 and translated into English in 1963. Scientific Papers of the Institute of Physical and Chemical Research, 1940. unknown
