John Nash (mathematician)

John Nash was a renowned mathematician renowned for his work in economics and game theory, notably the concept of the "Nash Equilibrium," a strategy where no player can improve their outcome by changing their choice alone. His contributions helped explain how individuals or organizations make rational decisions in competitive situations. Nash also made significant advances in pure mathematics and differential geometry. Despite struggles with mental illness, his ideas profoundly influenced economics, politics, and social sciences, earning him the Nobel Prize in Economics in 1994. His life story was popularized by the film "A Beautiful Mind."
