According to the obituary of the Tsung-Dao Lee Institute, the world-renowned scientist, Nobel Prize winner in physics, and Chinese-American physicist Tsung-Dao Lee died at his home in San Francisco at 2:33 a.m. on August 4, U.S. time, due to illness. He was 97 years old.

Tsung-Dao Lee was not only a giant in physics, but also actively promoted and facilitated the development of other scientific fields, and made great contributions to the cultivation of talents in the field of natural sciences in my country.

On November 24, 1926, Tsung-Dao Lee was born in Shanghai, Jiangsu Province, Suzhou. He was in school at a time of war, with the Japanese invasion of China and the outbreak of the Pacific War. Under extremely difficult conditions, Tsung-Dao Lee persisted in studying and was admitted to Zhejiang University. Later, due to the war, he moved to Kunming to study. Seeing his hard work and excellent academic performance, local teachers recommended Tsung-Dao Lee to study at Southwest Associated University, which was temporarily composed of Peking University, Tsinghua University and Nankai University.

In 1945, as a student of Peking University, Tsung-Dao Lee enrolled in the Department of Physics of Southwest Associated University, where Professor Wu Dayou provided him with the best physics education platform.

In 1946, recommended by Wu Dayou, Tsung-Dao Lee went to the United States to study, and studied under Nobel Prize winner and physics master Fermi at the University of Chicago, which had the most active frontier physics research at the time. Four years later, Tsung-Dao Lee received his doctorate from the University of Chicago and conducted research in the field of physics.

He has been engaged in physics research for a long time and has made pioneering and milestone work in many fields such as quantum field theory, elementary particle theory, nuclear physics, statistical mechanics, fluid mechanics, and astrophysics.

In 1957, Tsung-Dao Lee, who was just in his early 30s, and Chen-Ning Yang won the crown of physics - the Nobel Prize in Physics - with the law of parity non-conservation.

According to the website of the Tsung-Dao Lee Institute of Shanghai Jiao Tong University, the theory of parity non-conservation in weak interactions has completely changed the world's understanding of symmetry, opened a new door for human exploration of the microscopic world, and promoted the development of physics. For this, they jointly won the 1957 Nobel Prize in Physics. This is the first time that Chinese people have won this world's highest scientific honor, which has greatly boosted the national confidence and pride of the Chinese nation.

Li Zhengdao, who became a giant in physics, always cared about China's scientific education. On September 30, 1984, Li Zhengdao presided over a discussion meeting attended by relevant leaders of the Chinese Academy of Sciences and the Ministry of Education, and initially determined the "plan" for the establishment of a postdoctoral mobile station at the Institute of Theoretical Physics of the Chinese Academy of Sciences and the "regulations" for the trial implementation of the National Postdoctoral Science Fund (both drafts) that year.

In mid-1985, the State Council formally approved the trial implementation of the postdoctoral research system in my country, thus officially establishing the Chinese postdoctoral system.

After the reform and opening up, Tsung-Dao Lee frequently returned to China to give lectures to Chinese students and create opportunities for them to study abroad. He was committed to training young Chinese scientists to catch up with the gap in science and technology education with developed countries. When describing CUSPEA (China-US Joint Physics Graduate Program) he created, he said it was more meaningful than working on the law of parity non-conservation (a Nobel Prize-winning work).

These students lived up to expectations and achieved outstanding achievements in their respective research fields. Most of them chose to return to their motherland, becoming the backbone of the development of the country's scientific research and promoting the vigorous development of my country's natural sciences.

In 1957, after winning the Nobel Prize, Tsung-Dao Lee said: All scientific knowledge is uncertain.

Now, the only thing that is certain is that no one will care about the order of appearance with Yang Zhenning anymore.
