Lee, Tsung Dao (1926–)

Tsung Dao Lee

Tsung Lee is a Chinese-born American physicist who shared with Chen Ning Yang the 1957 Nobel Prize in Physics for their investigations of examples of the principle of parity being violated, which led to significant improvements in our understanding of subatomic particles. Lee and Yang showed that during weak interactions (see weak force) of elementary particles, the law of conservation of parity (that nature, in effect, makes no distinction between right- and lefthandedness) does not always apply. This was subsequently verified by experiment.
