Renowned physicist Chen-Ning Yang, who has passed away at the age of 103, will be remembered for his groundbreaking work that challenged long-held theories in physics. In 1957, Yang was awarded the Nobel Prize in Physics alongside Tsung-Dao Lee for their pioneering research on parity laws and mirror symmetry. Their findings paved the way for a deeper understanding of fundamental particles and forces.
Yang's career was marked by several significant contributions to theoretical physics. One such contribution was his attempt to develop a theory describing the nuclear force between protons and neutrons in 1953. Collaborating with Robert Mills, Yang proposed the concept of massless vector particles that would later become known as gluons. Although his work at the time faced skepticism from notable physicist Wolfgang Pauli, who questioned the existence of these particles due to their predicted "mass," Yang's persistence paid off.
The development of Yang-Mills theories, also known as gauge theories, laid the groundwork for our current understanding of electromagnetic forces and strong nuclear forces. Today, we recognize the importance of these vector particles in describing the weak and strong nuclear forces, including the W bosons that facilitate radioactive decays.
Yang's legacy extends beyond his work on fundamental particle physics. He made significant contributions to statistical mechanics and condensed matter physics, laying the foundation for large-scale research centers in China. Throughout his career, Yang received numerous awards, including the US National Medal of Science and the Albert Einstein medal.
Born in Hefei, China, Yang began his educational journey at National Southwestern Associated University in Yunnan before pursuing a PhD in the United States under the guidance of renowned physicist Edward Teller. He went on to have a distinguished career at various institutions, including the Institute for Advanced Study and Stony Brook University.
Yang's personal life was marked by two marriages and the raising of three children. His second wife, Weng Fan, survives him, along with their son Gilbert and daughter Eulee.
