沉痛悼念！杨振宁逝世

Core Points - Renowned physicist Yang Zhenning, a Nobel Prize winner and academician of the Chinese Academy of Sciences, passed away on October 18, 2025, in Beijing at the age of 103 [1] Group 1: Biography and Education - Yang Zhenning was born in 1922 in Hefei, Anhui, and moved to Tsinghua University in 1929. He entered Southwest Associated University in 1938 and graduated with a master's degree from Tsinghua University in 1944. He pursued further studies in the United States, earning a Ph.D. from the University of Chicago in 1948 [3] - He joined the Institute for Advanced Study in Princeton in 1949, became a permanent member in 1952, and was a professor there until 1999. He also held prestigious positions at Stony Brook University and the Chinese University of Hong Kong [3] Group 2: Contributions to Physics - Yang Zhenning is recognized as one of the greatest physicists of the 20th century, contributing significantly to modern physics. He co-developed the Yang-Mills theory, which laid the groundwork for the particle physics standard model, comparable to Maxwell's equations and Einstein's general relativity [4] - He, along with Li Zhengdao, proposed the revolutionary idea of parity violation in weak interactions, earning the Nobel Prize in Physics in 1957, making them among the first Chinese Nobel laureates [4] - Yang discovered the Yang-Baxter equation, which opened new directions in statistical physics and quantum groups, impacting various fields such as particle physics, field theory, statistical physics, and condensed matter physics [4] Group 3: Contributions to Education and Science in China - Yang Zhenning was deeply committed to his homeland, significantly contributing to China's science and education. He initiated a wave of visits by overseas Chinese scholars to China starting in 1971 and advocated for the restoration and strengthening of basic scientific research [5] - He established the "Committee for Educational Exchange with China," funding nearly a hundred Chinese scholars to study in the U.S., who later became key figures in China's technological development [5] - Upon returning to Tsinghua University, he dedicated himself to the development of the Institute for Advanced Study, greatly influencing the advancement of physics and talent cultivation at Tsinghua University and contributing to the reform and development of higher education in China [5]
