Chen-Ning Yang, a Nobel prizewinner, was an intuitive physicist whose theories on broken symmetries were proved right.
He helped to improve scientific relations between China and the United States.
Just as many of us are struck by the beauty of symmetrical patterns in nature and art, Chen-Ning Yang had a deep feeling for beauty and the role of symmetry in physics.
Yang's work on the breakdown of symmetry, proposed in 1956 with theorist Tsung-Dao Lee, suggested a fundamental difference between left and right in physics.
