September 29 ,1931 ) is an American nuclear physicist.Cronin was born in
Chicago, Illinois and attendedSouthern Methodist University inDallas, Texas . Cronin and co-researcherVal Logsdon Fitch were awarded the 1980Nobel Prize in Physics for a 1964 experiment that proved that certain subatomic reactions do not adhere to fundamental symmetry principles. Specifically, they proved, by examining the decay ofkaon s, that a reaction run in reverse does not merely retrace the path of the original reaction, which showed that the interactions of subatomic particles are not indifferent to time. Thus the phenomenon ofCP violation was discovered.Cronin is
Professor Emeritus at theUniversity of Chicago and a spokesperson for the Auger project. Cronin is a member of the Board of Sponsors of TheBulletin of the Atomic Scientists External links
