Li Zhengdao

Tsung-Dao Lee (English name: Tsung-Dao Lee, November 24, 1926 - August 4, 2024), a Chinese-American physicist, famous for his achievements in parity non-conservation, Lee Model, Yang-Li theorem, particle physics, relativistic heavy ion (RHIC) physics, non-topological solitons and soliton stars in quantum field theory. He served as professor emeritus at Columbia University, lecturing from 1953 to 2012. In 1957, 31-year-old Lee Tsung-dao and fellow Chinese physicist Chen Ning Yang won the Nobel Prize in Physics for their discovery of parity nonconservation under weak interactions. The theory was confirmed by the Wu experiment of another Chinese physicist, Wu Jianxiong. Lee was once the youngest Nobel Prize winner after World War II. This record was not broken until Malala Yousafzai won the Nobel Peace Prize in 2014. He is also the fourth youngest Nobel Prize winner in history, behind William Lawrence Bragg (25 years old, 1915), Werner Heisenberg (30 years old, 1932) and Malala (17 years old, 2014). Tsung-Dao Lee and Chen-Ning Yang are the first two Chinese Nobel Prize winners. Even after becoming a naturalized American citizen in 1963, Lee Tsung-dao was still the youngest American Nobel Prize winner.
