Sin-Itiro Tomonaga (1906–1979)

Born in Tokyo, the son of a philosophy professor, Sin-Itiro Tomonaga studied quantum mechanics with Hideki Yukawa at Kyoto University. After attending lectures at Kyoto by Paul Dirac and Werner Heisenberg, Tomonaga did research for the Japanese Navy on microwave theory, while continuing his mostrar más research in quantum theory. From 1937 to 1939, he worked under Heisenberg in Germany. As early as 1942, Tomonaga suggested a new formulation of many ideas in the quantum field theory. Moreover, it was Tomonaga's theoretical work in developing a completely relativistic quantum field theory that led to the first successful form of quantum electrodynamics. Other forms were later developed independently by Julian Schwinger and Richard Feynman, who shared a Nobel Prize in physics with Tomonaga in 1965. In 1955 Tomonaga established the Institute for Nuclear Studies at the University of Tokyo and became president of the Tokyo University of Education in 1956. Later, he headed the Science Council for Japan and wrote popular books on quantum mechanics. (Bowker Author Biography) mostrar menos
