Tsung-Dao Lee

Tsung-Dao Lee was born on November 24, 1926 in Shanghai, China, American, is Physicist. Tsung-Dao Lee is a distinguished Chinese-American physicist, who jointly received the ‘Nobel Prize in Physics’ in 1957 with another physicist Chen-Ning Franklin Yang for their significant work on the violations of the principle of parity conservation. The duo established theoretically that conservation of parity, one of the fundamental laws of quantum-mechanics is violated in the nuclear procedure that result in emitting alpha or beta particles, that is to say in weak nuclear reagents. This discovery led to significant alterations and refinements in the field of particle physics. They concluded that tau-meson and theta-meson, which were earlier comprehended to be different particles due to their decaying by modes of differing parity, are actually same (presently called K-meson). Their theory was experimentally validated by fellow physicist Chien-Shiung Wu in 1957. Apart from parity violation, Lee is also known for his work in non-topological solitons and soliton stars, relativistic heavy ion (RHIC) physics and the Lee Model. At present he is the University Professor Emeritus at ‘Columbia University’ where he taught for almost six decades. While he and Yang became first Chinese Nobel Laureates, he was youngest Nobel laureate since Second World War till 2014 when Malala Yousafzai received ‘Nobel Peace Prize’. After becoming a naturalized American citizen in 1962, he remains the youngest American ever to receive a ‘Nobel Prize’.

Professor Wu nominated Lee for a Chinese government fellowship for graduate study in US. In 1946, Lee went to the University of Chicago and was selected by Professor Enrico Fermi to become his PhD student. Lee received PhD under Fermi in 1950 for his research work Hydrogen Content of White Dwarf Stars. Lee served as research associate and lecturer in physics at the University of California at Berkeley from 1950 to 1951.


Chin and Lee were married in 1950 and have two sons: James and Stephen. Lee reads whodunit novels when not working on physics. The English spelling of his given name, "Tsung-Dao", differs slightly from the standard Chinese Romanization systems in use at the time of his childhood, Wade–Giles and Gwoyeu Romatzyh. Tsung-Dao Lee's publications are all under the name of T.D. Lee.


In 1953, Lee joined Columbia University, where he remained until retirement. His first work at Columbia was on a solvable model of quantum field theory better known as the Lee Model. Soon, his focus turned to particle physics and the developing puzzle of K meson decays. Lee realized in early 1956 that the key to the puzzle was parity non-conservation. At Lee's suggestion, the first experimental test was on hyperion decay by the Steinberger group. At that time, the experimental result gave only an indication of a 2 standard deviation effect of possible parity violation. Encouraged by this feasibility study, Lee made a systematic study of possible P,T,C and CP violations in weak interactions with collaborators, including C. N. Yang. After the definitive experimental confirmation by C.S. Wu and her collaborators of parity non-conservation, Lee and Yang were awarded the 1957 Nobel Prize for Physics.


In 1957, Lee, at the age of 30, won the Nobel Prize in Physics with Franklin C N Yang for their work on the violation of the parity law in weak interactions, which Chien-Shiung Wu experimentally verified in 1956, with her so-called Wu experiment.


In the early 1960s, Lee and collaborators initiated the important field of high Energy neutrino physics. In 1964, Lee, with M. Nauenberg, analyzed the divergences connected with particles of zero rest mass, and described a general method known as the KLN theorem for dealing with these divergences, which still plays an important role in contemporary work in QCD, with its massless, self-interacting gluons. In 1974–75, Lee published several papers on "A New Form of Matter in High Density", which led to the modern field of RHIC physics, now dominating the entire high Energy nuclear physics field.


Besides particle physics, Lee has been active in statistical mechanics, astrophysics, hydrodynamics, many body system, solid state, lattice QCD. In 1983, Lee wrote a paper entitled, "Can Time Be a Discrete Dynamical Variable?"; which led to a series of publications by Lee and collaborators on the formulation of fundamental physics in terms of difference equations, but with exact invariance under continuous groups of translational and rotational transformations. Beginning in 1975, Lee and collaborators established the field of non-topological solitons, which led to his work on soliton stars and black holes throughout the 1980s and 1990s.


From 1997 to 2003 Lee was Director of the RIKEN-BNL Research Center (now Director emeritus), which together with other researchers from Columbia, completed a 1 teraflops supercomputer QCDSP for lattice QCD in 1998 and a 10 teraflops QCDOC machine in 2001. Most recently, Lee and Richard Friedberg have developed a new method to solve the Schrödinger Equation, leading to convergent iterative solutions for the long-standing quantum degenerate double-wall potential and other instanton problems. They have also done work on the neutrino mapping matrix.


In 1998, Lee established the Chun-Tsung Endowment (秦惠䇹—李政道中国大学生见习基金) in memory of his wife, who had died 3 years earlier. The Chun-Tsung scholarships, supervised by the United Board for Christian Higher Education in Asia (New York), are awarded to undergraduates, usually in their 2nd or 3rd year, at six universities, which are Shanghai Jiaotong University, Fudan University, Lanzhou University, Soochow University, Peking University and Taiwan National Tsing Hua University. Students selected for such scholarships are named "Chun-Tsung Scholars" (䇹政学者).


Lee was the youngest Nobel laureate after World War II until Malala Yousafzai was awarded the Nobel Peace Prize in 2014. He is the fourth youngest Nobel laureate in history after william L. Bragg (who won the prize at 25 with his father william H. Bragg in 1915), Werner Heisenberg (who won in 1932 also at 30) and Malala Yousafzai (awarded at just 17). Lee and Yang were the first Chinese laureates. Since he became a naturalized American citizen in 1962, Lee is also the youngest American ever to have won a Nobel Prize.
