Yang Chen-Ning, a Rare card

The card carries these facts from its Wikipedia article.

• Yang is known for his collaboration with Robert Mills in 1954 in developing non-abelian gauge theory, widely known as the Yang–Mills theory, which describes the nuclear forces in the Standard Model of particle physics.
• Yang and Tsung-Dao Lee received the 1957 Nobel Prize in Physics for their work on parity non-conservation of the weak interaction, which was confirmed by the Wu experiment in 1956.
• The two proposed that the conservation of parity, a physical law observed to hold in all other physical processes, is violated in weak nuclear reactions – those nuclear processes that result in the emission of beta particles.
