Chen Ning Yang

Chen-Ning Franklin Yang ( /jɑːŋ,jæŋ/; born October 1, 1922), also known as Yang Zhenning, is a Chinese-born American physicist who works on statistical mechanics and particle physics. He and Tsung-dao Lee received the 1957 Nobel prize in physics for their work on parity nonconservation of weak interaction, proved experimentally that one of the basic quantum-mechanics laws, called the conservation of parity, is violated in the so-called weak nuclear reactions, those nuclear processes that result in the emission of beta or alpha particles of nuclear's radioactivities reactions. Yang became a naturalized American citizen in 1964.
