I C.N. Yang dies at age 103

[ohwilleke]

TL;DR

Eminent theoretical particle physicist C.N. Yang has died at age 103.

Theoretical physicist C.N. Yang died at the age of 103 years on October 18, 2025.

He is the Yang in Yang-Mills theory, which he and his collaborators devised in 1953, which is a generic quantum field theory that is used by scientists to study amplitudes (i.e. vector probabilities) that are foundational in all Standard Model processes and most quantum gravity theories.

He also won a Nobel prize in 1957 for his work on CP violation.

(I didn't see the post in General Discussions at PF on his death before making this post.)

Here's a short but tasteful obituary (hope the link wasn't already posted. I searched. Also in that other thread.):

TL;DR: Eminent theoretical particle physicist C.N. Yang has died at age 103.

He also won a Nobel prize in 1957 for his work on CP violation.

It was actually P-violation (discovered in 1956).
