John von neumann (190365438+February 28th-1February 8th, 957), an American Hungarian mathematician, computer scientist and physicist, was one of the most important mathematicians in the 20th century.

Von Neumann is a doctoral student majoring in mathematics at Roland University. He is one of the scientific generalists in the fields of modern computer, game theory, nuclear weapons and biochemical weapons. Later generations called it "the father of modern computers" and "the father of game theory". ?

Von Neumann taught at the University of Berlin and the University of Hamburg, went to the United States in 1930, and later became an American citizen. He was a professor at Princeton University and a professor at Princeton Institute for Advanced Studies. He was elected as a member of the American Atomic Energy Commission and the National Academy of Sciences.

In his early days, he was famous for his research on operator theory, vibration theory, quantum theory and set theory, and founded von Neumann algebra. Von Neumann participated in the Manhattan Project during World War II and contributed to the development of the first atomic bomb.

In 1944, von Neumann co-authored Game Theory and Economic Behavior with Oscar Morgenstein, which is the foundation work of game theory. In his later years, Von Neumann turned to the study of automata theory, and wrote a book "Computer and Human Brain" (1958), which made an accurate analysis of human brain and computer system, and provided a basic scheme for the development of electronic digital computers.

Other major works include Mathematical Basis of Quantum Mechanics (1926), Operator Method of Classical Mechanics and Continuous Geometry (1960).
