Chen Ning Yang is a Chinese theoretical physicist known for his significant contributions to statistical mechanics, gauge theory, integrable systems, and both particle physics and condensed matter physics. He and Tsung-Dao Lee were awarded the 1957 Nobel Prize in Physics for their work on parity nonconservation of weak interaction. The men also elucidated the Lee-Yang circle theorem.
Tsung-Dao Lee is a Chinese-American physicist renowned for his work on particle physics, parity violation, soliton stars, nontopological solitons, and the Lee Model. In 1957, he became the third-youngest person to be awarded the prestigious Nobel Prize in the science fields; he won the Nobel Prize in Physics. He is also the first Chinese Nobel laureate.
