Chen Ning Yang
Chen-Ning Franklin Yang (born October 11922) is a Chinese-born American physicist who worked on statistical mechanics and symmetry principles.

In 1957, at the age of 35, he and Tsung-Dao Lee received the Nobel Prize in Physics for their theory that weak force interactions between elementary particles did not have parity (mirror-reflection) symmetry. (Chien-Shiung Wu experimentally verified the theory.) Yang's relationship with Lee turned sour around 1962 after they had received the Nobel Prize. Their quarrel has been who, among the two of them, first proposed the idea of parity non-conservation for weak interaction, up to the present day.
