MOSCOW, August 6 Chinese-American physicist Li Zhengdao, who won the Nobel Prize for his research in particle physics, has died at the age of 97, CGTN reported, citing the Institute of Physics high-energy physicists of the Chinese Academy of Sciences.
According to the TV channel, the scientist died at his home in San Francisco.
Born in Shanghai, Li Zhengdao studied in graduate school at the University of Chicago under the famous physicist Enrico Fermi.
Throughout his career, he made pioneering contributions to particle physics, nuclear theory, and statistical mechanics. In 1954, he introduced the renormalizable model of field theory, commonly known as the «Lie model,» which played a major role in resolving fundamental questions in quantum field theory.
In 1956, Li discovered parity violation in weak interactions. This groundbreaking work was experimentally confirmed the following year, fundamentally changing the understanding of symmetry in physics. The discovery earned him the Nobel Prize in Physics and the Albert Einstein Science Award in 1957. At age 31, Lee became the second-youngest scientist ever to win a Nobel Prize.
