Work
Gauge symmetry expresses fundamental forces through geometry, linking field theory with the language of connections and curvature.
Yang, with Robert Mills, introduced non-Abelian gauge theory, while his broader work connected symmetry principles to physical law.
Yang-Mills theory became a foundation of the Standard Model and a deep meeting point between physics and geometry.
