According to CCTV news, Mr. Tsung-Dao Lee, a famous Chinese physicist and Nobel laureate in physics, passed away at the age of 98.
Professor Tsung-Dao Lee has not only made important contributions to many fields of physics, but also left an indelible mark on education, research management and international academic collaboration.
Remember the life of this great physicist, and look back on his outstanding achievements and great legacy.
The life and achievements of Professor Tsung-Dao Lee
Tsung-Dao Lee, born in Shanghai, China in 1926, originally from Suzhou, Jiangsu, is a Chinese-American physicist, a foreign academician of the Chinese Academy of Sciences, an academician of the United States National Academy of Sciences, an academician of the Italy Linqin Academy of Sciences, an academician of the United States Academy of Arts and Sciences, and a Nobel Prize winner in physics.
From 1944 to 1946, he studied at Zhejiang University and Southwest Associated University. He received his Ph.D. from the University of Chicago in United States in 1950. He was appointed Professor at United States Colombia University in 1956, Professor at the Institute for Advanced Study in Princeton in 1960, Fermi Chair Professor at Colombia University since 1964, and Chair Professor at Colombia University since 1984.
Tsung-Dao Lee has been engaged in physics research for a long time, and has made a series of landmark works in the fields of particle physics theory, atomic nucleus theory and statistical physics.
In 1954, Tsung-Dao Lee proposed the "Lie model", which played an important role in exploring the basic problems of quantum field theory. In 1956, together with Yang Zhenning, he proposed the thesis that the universe is not conserved in weak interactions, and the following year, after experimental verification, he jointly won the Nobel Prize in Physics and the Einstein Prize in Science.
Since the 60s of the last century, Tsung-Dao Lee has systematically studied the problem of non-conservation under the combined transformation of positive and negative particles and spatial reflection.
Since the 70s of the last century, Tsung-Dao Lee has made pioneering contributions to the establishment and development of the quantum theory of solitons, the concept of anomalous nuclear states, the establishment and development of the gauge theory of random lattices, and the establishment of discrete dynamics theory by taking time as a discrete dynamic variable.
In 1994, Lee was elected as a foreign academician of the Chinese Academy of Sciences.
The first Chinese to win the Nobel Prize
In 1956, Professor Tsung-Dao Lee cooperated with Yang Chen-ning to propose the theory of cosmic non-conservation in weak interactions, which completely overturned the traditional concept of physics. In 1957, Lee Zhengdao and Yang Zhenning jointly won the Nobel Prize in Physics for this pioneering work, becoming the first Chinese to win the Nobel Prize. This achievement not only won him an international reputation, but also played an important role in promoting the status of Chinese scientists in the world.

Contribution to the physics community
In addition to the theory of non-conservation of universal symmetry, Professor Tsung-Dao Lee has made many important contributions to the field of particle physics. His Lie-Yang theory provided new perspectives and methods for later particle studies.
In addition, Tsung-Dao Lee has also made remarkable achievements in the fields of high-energy physics, quantum field theory, and statistical mechanics. He co-developed relativistic fluid dynamics equations with his collaborators, which are widely used in nuclear physics and astrophysics research.
Lee Tsung-dao has always been concerned about the cause of science education in the motherland
Since 1972, he has returned to China many times to give lectures and make suggestions, and after the reform and opening up, he has spared no effort to promote the progress of China's science education, and has made irreplaceable contributions to the strategic layout of China's science education, the frontier exploration of high-energy physics, the cultivation of high-level talents, and international exchanges and cooperation.
From 1979 to 1989, he initiated and participated in the organization and implementation of the Sino-US Joint Physics Graduate Program (CUSPEA), selected and recommended 915 people to study in the United States, created a group of leading scholars and social pillars, and created a new paradigm for the cultivation of high-level talents urgently needed in the mainland. In 1985, he advocated the establishment of a postdoctoral system and the establishment of the China Postdoctoral Science Foundation, and continued to build hundreds of thousands of new forces in scientific and technological innovation in the mainland. In 1998, he initiated the establishment of the Qin Huicheng and Lee Tsung-Dao Chinese College Students Internship and Training Fund, which selectively cultivated thousands of basic science reserve troops in the mainland, and became an important carrier for the cultivation of innovative talents in the mainland.
The legacy and influence of Professor Tsung-Dao Lee
After the passing away of Professor Tsung-Dao Lee, his scientific legacy will continue to influence future research and development. The academic institutions and foundations he created will continue to support scientific research and education around the world. His writings and academic papers will continue to inspire future scientists. His remarkable achievements are not limited to science itself, but also to inspire generations of young scholars to pursue truth and explore the unknown.
