Maskawa, Toshihide,1940–, Japanese physicist, Ph.D. Nagoya Univ., 1967. Maskawa was a research associate at Nagoya Univ. from 1967–70 and then joined the faculty at Kyoto Univ., where he was appointed emeritus professor in 2003. Maskawa shared the 2008 Nobel Prize in Physics with Makoto KobayashiKobayashi, Makoto,
1944–, Japanese physicist, Ph.D. Kyoto Univ., 1972. Kobayashi taught at Kyoto Univ. (1972–79) and the National Laboratory of High Energy Physics, Tsukuba, Japan (1979–97).

(Broken symmetry explains the asymmetry in nature known as CP violation, which results in a universe consisting of mostly of matter, instead of equal amounts of matter and antimatter.) The existence of the predicted quarks has since been confirmed in experiments.
