Chen-Ning Yang, the 103-year-old Chinese American physicist who won the Nobel Prize in Physics in 1957 for his groundbreaking work on parity laws, has passed away.
Yang's life was marked by a remarkable journey from China to the United States and back again. Born in Hefei, China, he graduated from National Southwestern Associated University in Yunnan in 1942 before winning a scholarship to pursue his PhD studies at the University of Chicago. Under the guidance of Edward Teller, Yang completed his PhD in 1948.
Yang's work on parity laws revolutionized the field of particle physics by challenging the widely accepted notion that fundamental forces acting on subatomic particles are symmetric between left and right. Alongside Tsung-Dao Lee, Yang shared the Nobel Prize for their work in 1957. This breakthrough led to a deeper understanding of gauge theories, which is now a cornerstone of modern particle physics.
Yang's contributions extended far beyond his Nobel Prize-winning work. He made significant contributions to statistical mechanics and condensed matter physics, laying the groundwork for later discoveries in these fields. In his later years, Yang played a key role in establishing large-scale research centers in China.
One of Yang's most notable failures was during a seminar at Princeton's Institute for Advanced Study in 1954, where he faced criticism from the renowned physicist Wolfgang Pauli. Pauli questioned Yang's theory on vector particles and their mass, leaving Yang feeling uncertain about his work. However, Yang persevered and his insights ultimately led to the discovery of massive vector particles, now known as W bosons.
Yang's legacy is a testament to his perseverance and innovative spirit. His work laid the foundation for modern theories that describe electromagnetic strong and weak forces. The discovery of the Higgs boson in 2012 provided the missing piece of the puzzle, further solidifying Yang's contributions to our understanding of particle physics.
Yang is survived by his wife Weng Fan, as well as his children from previous marriages.
