Short Summary
Chen-Ning Yang is a renowned physicist celebrated for his significant contributions to theoretical physics, particularly in the field of statistical mechanics and particle physics. Born in China in 1922, he co-proposed the Yang-Mills theory, which became a cornerstone in the development of the Standard Model of particle physics. He was awarded the Nobel Prize in Physics in 1957, alongside Tsung-Dao Lee, for their work on the law of parity violation. Yang's groundbreaking research has left an indelible mark on modern physics.
Early Life & Education
Chen-Ning Yang was born on September 22, 1922, in Hefei, Anhui Province, China. His father was a mathematician, which greatly influenced his early interest in science and mathematics. Yang attended Tsinghua University in Beijing, where he earned his bachelor's degree in 1942. He then moved to the United States to pursue graduate studies at the University of Chicago, where he obtained his Ph.D. in 1948 under the supervision of Edward Teller. Yang's educational journey was marked by a strong foundation in theoretical physics, setting the stage for his future contributions.
Career Highlights
After completing his Ph.D., Chen-Ning Yang joined the Institute for Advanced Study in Princeton, New Jersey, where he collaborated with some of the most prominent physicists of the time. In 1954, he co-developed the Yang-Mills theory with Robert Mills, which has become a fundamental part of particle physics. In 1957, he and Tsung-Dao Lee discovered that parity is not conserved in weak nuclear interactions, leading to their Nobel Prize in Physics. Yang later joined the faculty at Stony Brook University, significantly contributing to the institution's rise as a center for scientific research.
