5. Known for
Yang Zhenning is known for his work on the symmetry properties of subatomic particles. This work helped to lay the foundation for the Standard Model of particle physics, which is our current understanding of the fundamental forces and particles that make up the universe.
- Parity violation: Parity is a symmetry that says that the laws of physics are the same for left-handed and right-handed coordinate systems. In 1956, Yang and Tsung-Dao Lee showed that parity is violated in the weak force, which is the force responsible for radioactive decay. This discovery was a major breakthrough in physics and helped to pave the way for the development of the Standard Model.
- Charge conjugation symmetry: Charge conjugation symmetry is a symmetry that says that the laws of physics are the same for particles and antiparticles. In 1957, Yang and Lee showed that charge conjugation symmetry is also violated in the weak force. This discovery further supported the idea that the weak force is a unique and fundamental force of nature.
- CP violation: CP violation is a symmetry that combines parity and charge conjugation symmetry.
