Lee Tszuedao (Lee Tsung Dao)

(p. 1926)
Awarded in 1957 Nobel Prize in Physics (jointly with C. Yang) for the discovery of parity violation. Born November 24, 1926 in Shanghai. He studied at Shanghai University. In 1946, received a state scholarship, continued his education at the University of Chicago. In 1950 received his Ph.D.. In 1950-1951 he worked at the University of California, in 1951-1953 and 1960-1963 - in the Princeton Institute for Basic Research in 1953 - at Columbia University (since 1956 - professor of the University).
Works of Li are quantum field theory, theory of elementary particles, statistical mechanics, astrophysics. In 1954 the suggested model of quantum field theory (Lee model). In 1956, Lee and his compatriot Charles Young came to the conclusion that the q-and t-mesons were considered different particles, in fact - an elementary particle, the K-meson. This discovery led them to conclude that the weak interactions of the law of conservation of parity ( 'right' or 'left' direction of spin of particles and some of their other characteristics) is not satisfied. Lee and Yang proposed the idea of an experiment to test this hypothesis, which in 1957 confirmed the correctness of the theoretical output of scientists. For this discovery they were awarded the Nobel Prize. In 1960, together with Lee Young has suggested that the weak interaction due to intermediate vector bosons, and the postulated properties. Subsequent work relate to the theory of gauge invariance (the theory of fields).
