To quote Freeman Dyson: "Professor Yang is, after Einstein and Dirac, the preeminent stylist of the 20th century physics. From his early days as a student in China to his later years as the sage of Stony Brook, he has always been guided in his thinking by a love of exact analysis and formal mathematical beauty. This love led him to his most profound and original contribution to physics, the discovery with Robert Mills of non-Abelian gauge fields. With the passage of time, his discovery of non-Abelian gauge fields is gradually emerging as a greater and more important event than the spectacular discovery of parity non-conservation which earned him the Nobel Prize."
He once "leaked" the idea that Jim Simon's trading success came from his use of ideas called "gauge theory" and "fibre bundles".

> Ning attended the prestegious Princeton Institute for Advanced Study.
Yang-Mills theory for electro-magnetic force is grounded in integratable systems, a gauge theory in statistics, etc for elementary particles.
