John C. Nash

John C. Nash was an influential American mathematician known for his work on game theory, which analyzes strategic interactions where individuals or groups make decisions that affect each other. His most famous contribution is the Nash Equilibrium, a concept describing a stable situation where no participant can improve their outcome by changing their strategy alone. Nash's insights have impacted economics, politics, and business, helping to explain how competitive and cooperative behaviors develop in complex systems. His work earned him the Nobel Memorial Prize in Economic Sciences in 1994, recognizing his profound influence on understanding strategic decision-making.
