Abstract

On August 4 this year, Tsung-Dao Lee, a renowned theoretical physicist of Chinese origin, passed away at the age of 97. His most famous discovery dates back to 1956, when -- together with Chen-Ning Yang -- he postulated that parity symmetry might be broken by the weak interaction. They suggested experimental tests of this revolutionary idea, which were conducted within one year. The results confirmed the conjecture by Lee and Yang, thus changing a core paradigm of physics.
