Bruce Winstein (25 September 1943, Los Angeles – 28 February 2011) was an experimental physicist and cosmologist noted for his early work in elementary particle physics, particularly work toward demonstrating a serious asymmetry between particles and their anti-particles (CP violation). Later in his career, he worked in experimental cosmology, measuring polarization in the microwave background radiation whose properties date back to the early universe. ==Career== After a distinguished early career in experimental elementary particle physics, Winstein spent a year in Princeton as a Guggenheim Fellow, learning about astrophysics in general and the microwave background radiation in particular.〔 He then returned to his position as the Samuel K. Alison Distinguished Service Professor in Physics at the University of Chicago, where he founded its NSF Physics Frontier Center for Cosmological Physics.〔 In 1999, he was leader of Fermilab's KTeV experiment, which produced the first definitive evidence for direct CP violation, an important proof that that matter and anti-matter are not perfect twins.〔("Bruce Winstein, physicist, 1943-2011" (University of Chicago News, March 3, 2011) )〕 He was also leader of the QUIET experiment, a multi-year international collaboration that sought to detect gravity waves in the early universe by measuring polarization in the microwave background radiation.〔〔(【引用サイトリンク】url=http://kicp.uchicago.edu/research/projects/quiet.html )〕 He received his B.S. degree in Physics and Math from UCLA and his PhD. in 1970 from CalTech. Winstein was inducted into the National Academy of Science in 1995 and to the American Academy of Arts and Sciences in 2007. Also in 2007, he was awarded the W,H, Panofsky Prize in Experimental Particle Physics by the American Physical Society. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bruce Winstein」の詳細全文を読む スポンサード リンク
