Chen-Ning Yang, a Chinese-American theoretical physicist who has passed away at the age of 103, was awarded the Nobel Prize in Physics in 1957. Born in Hefei, China, and raised in Beijing, Yang would go on to make groundbreaking contributions to the field of particle physics.
In 1950, while working at the Institute for Advanced Study in Princeton, New Jersey, Yang befriended Tsung-Dao Lee, another young Chinese émigré. Together, they overturned the widely accepted "parity laws" that stated fundamental subatomic particles had symmetrical forces acting on them. This breakthrough led to a new understanding of mirror symmetry and paved the way for Yang's work on gauge theories.
Yang's most notable contribution was his development of the Yang-Mills theories, which describe the weak and strong nuclear forces. His idea, first conceived in 1953, revolutionized our understanding of the fundamental forces of nature. However, this breakthrough came with a price – Yang faced skepticism from prominent physicists, including Wolfgang Pauli, who questioned the validity of his theory.
One fateful seminar at Princeton's Institute for Advanced Study marked a turning point for Yang. Pauli's scathing criticism of his work left Yang visibly shaken. The event was later immortalized in letters between Yang and Pauli, which revealed the depth of their intellectual rivalry. Despite this setback, Yang persevered and continued to develop his theories.
Yang's groundbreaking work on gauge theories laid the foundation for our modern understanding of particle physics. His insight into the violation of mirror symmetry, combined with the development of the Higgs boson mechanism in 2012, formed the cornerstone of today's standard model of particles and forces.
Throughout his illustrious career, Yang held various positions at prominent institutions, including Stony Brook University and Tsinghua University in China. He was also a recipient of numerous awards, including the US National Medal of Science and the Albert Einstein medal.
Yang is survived by his wife Weng Fan, as well as their two sons from his previous marriage.
