Renowned physicist Chen-Ning Yang has passed away at the ripe age of 103. The Chinese American theoretical physicist had made groundbreaking contributions to the world of physics that earned him the prestigious Nobel Prize in Physics in 1957.
Yang's journey to fame began when he befriended fellow scientist Tsung-Dao Lee during a period of collaboration at Princeton University in New Jersey, USA. Together, they shook the foundations of traditional knowledge by challenging the widely accepted "parity laws," thereby paving the way for new understanding of fundamental forces acting on subatomic particles.
Yang's most impactful contribution came from an idea he conceived in 1953, which was later developed into Yang-Mills theories with the help of his doctoral student Robert Mills. This theory successfully described both the weak and strong nuclear forces and laid the groundwork for our current understanding of these forces.
The reaction to Yang's nascent career was not kind, however. His proposal during a seminar at Princeton's Institute for Advanced Study in 1954 was met with skepticism by Wolfgang Pauli, who expressed his disdain for Yang's ideas. This encounter proved to be a defining moment for Yang, and it took until the work of Peter Higgs and others was completed in 1964 that he realized that massless vector particles could acquire mass.
Yang-Mills theories have since become a cornerstone of particle physics, shaping our understanding of electromagnetic forces (strong) and weak nuclear forces. The discovery of the Higgs boson in 2012 confirmed a critical piece of the puzzle, finally filling the gap left by Yang's insight into mirror symmetry.
Throughout his illustrious career, Yang has also made significant contributions to statistical mechanics and condensed matter physics. After retiring from Stony Brook University in 1999, he returned to China and continued to play a vital role in establishing large-scale research centers across the country.
In recognition of his groundbreaking work, Yang received numerous awards, including the US National Medal of Science (1986) and the Albert Einstein medal in 1995. He is survived by his children from two marriages, Weng Fan, who was his second wife, and his daughter Eulee, along with their children Franklin, Gilbert, and grandchildren.
Yang's passing marks the end of an era, leaving behind a legacy that has reshaped our understanding of fundamental forces in the universe. His tireless pursuit of knowledge will continue to inspire future generations of scientists and researchers.
