Affiliation at the time of the award: Cornell University, Ithaca, NY, USA
Prize motivation: "for his theory for critical phenomena in connection with phase transitions."
Prize share: 1/1
An accumulation of matter with uniform physical and chemical properties is said to be in a certain phase, such as solid, liquid or gas. There also are other phases, for example, when dealing with magnetism. A theoretical understanding of critical points for phase transitions requires a broad spectrum of scaling. Early attempts to explain this in one step led to infinities in the result. Kenneth Wilson solved the problem in 1971 through a type of renormalization, which can be described as solving the problem piece by piece.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
