Chien-Shiung Wu was a Chinese-American experimental physicist known for her significant contributions to the field of nuclear physics. Born on May 31, 1912, in Shanghai, China, she moved to the United States in the 1930s, where she conducted groundbreaking research, particularly in the study of beta decay. Wu is best known for her work on the Wu experiment, which provided critical evidence for the theory of weak interaction and challenged the previously held belief in the conservation of parity. Her findings played a crucial role in the development of the Standard Model of particle physics, earning her recognition as one of the leading physicists of her time.
