Biography

TsungDao Lee is a ChineseAmerican theoretical physicist who, alongside Chen Ning Yang, demonstrated the violation of parity conservation in weak interactions—a revolutionary discovery that fundamentally challenged decades of accepted physics. At just 31, he became one of the youngest Nobel laureates in Physics (1957), fundamentally reshaping our understanding of the universe's underlying symmetries. His work opened entirely new directions in particle physics and earned him lasting influence across both theoretical research and physics education.
