Study Notes

Yang Chen-Ning's Life and Work

  • Yang Chen-Ning was a Chinese-born theoretical physicist who revolutionized particle physics.
  • He won the Nobel Prize in Physics for his work in 1957.

Key Contributions to Physics

  • Yang challenged the accepted law of conservation of parity.
  • He proposed that this law did not hold true for certain "weak interactions", such as radioactive decay.
  • He worked with Tsung-Dao Lee to prove the conservation of parity was not always true.
  • This led to a new understanding of particle interactions at the subatomic level.
  • Yang and Lee proposed an experiment to test their hypothesis, which Chien-Shiung Wu successfully conducted.
  • Yang also proposed the Yang-Mills theory on elementary particles in 1954.

Milestones in Yang's Career

  • Yang left China in 1946 to study physics at the University of Chicago.
  • He moved to Princeton in 1949 to study subatomic decay.
  • In 1965, he became director of the theoretical physics research center at Stony Brook University.

Quote

  • "These concepts were not dreamed up. They were natural and real," said Shiing-Shen Chern in 1975.
