Yin and yang, also yinyang or yin-yang, is a concept that originated in Chinese philosophy, describing opposite but interconnected, mutually perpetuating forces. The technology of Yin and yang is the foundation of critical and deductive reasoning for effective differential diagnosis of disease and illnesses within Confucian influenced traditional Chinese medicine.
Yang Chen-Ning or Chen-Ning Yang, also known as C. N. Yang or by the English name Frank Yang, is a Chinese theoretical physicist who made significant contributions to statistical mechanics, integrable systems, gauge theory, and both particle physics and condensed matter physics. He and Tsung-Dao Lee received the 1957 Nobel Prize in Physics for their work on parity non-conservation of weak interaction. The two proposed that one of the basic quantum-mechanics laws, the conservation of parity, is violated in the so-called weak nuclear reactions, those nuclear processes that result in the emission of beta or alpha particles. Yang is also well known for his collaboration with Robert Mills in developing non-abelian gauge theory, widely known as the Yang–Mills theory.
