description Chien-Shiung Wu Overview
Chien-Shiung Wu (1912-1997) was a Chinese-American experimental physicist who conducted the landmark Wu experiment, disproving the law of parity in beta decay. This pivotal discovery earned her international recognition and solidified her place as one of the most influential physicists of the 20th century.
help Chien-Shiung Wu FAQ
What was Chien-Shiung Wu's parity experiment?
Wu led the 1956 beta decay experiment using cobalt-60 that showed parity is not conserved in weak interactions. The result confirmed the theory proposed by Tsung-Dao Lee and Chen-Ning Yang.
Did Chien-Shiung Wu win the Nobel Prize for the Wu experiment?
No. Lee and Yang received the 1957 Nobel Prize in Physics for the parity work, but Wu was not included, a decision often discussed as a major omission.
Where did Chien-Shiung Wu do her major physics work?
Wu spent much of her career at Columbia University in New York. During World War II, she also contributed to Manhattan Project related work on radiation detection and uranium enrichment problems.
Why is Chien-Shiung Wu sometimes called the First Lady of Physics?
The nickname reflects her status as one of the 20th century's leading experimental physicists. Her work on beta decay was precise enough to overturn a principle many physicists had treated as fundamental.
