Chien-Shiung Wu

Born 29 May 1912; died 16 Feb 1997 at age 84. Chinese-American physicist who provided the first experimental proof (1956) that parity is not conserved in weak subatomic interactions of nuclear beta decay. When two physicists, Tsung-Dao Lee, and Chen Ning Yang proposed that parity was not conserved for weak interactions, Dr. Wu tested the proposal by observing the beta particles given off by cobalt-60. She observed that there is a preferred direction of emission, and that therefore, parity was not conserved for this weak interaction. In other words, Dr. Wu was able to prove that identical nuclear particles do not always act alike, and, thereby, disprove, what was then, a widely accepted “law” of nature.
