Contributions Quantum physics, functional analysis, set theory, topology, economics, computer science, numerical analysis, hydrodynamics (of explosions), statistics and many other mathematical fields as one of history's outstanding mathematicians. Most notably, von Neumann was a pioneer of the application of operator theory to quantum mechanics

Outstanding contributions in the areas of mathematics Established the theory of operator rings laid the mathematical foundation of quantum mechanics Applied mathematics, in mechanics, economics, numerical analysis and have important contribution to the electronic calculator Participated in the 1944 world's first electronic calculator design, Proposed the Monte Carlo method in the development process of the atomic bombthe Monte Carlo method

Greatest Achievements in the Life Join the development plan for ENIAC computer in 1944 A new general-purpose stored program computer program (EDVAC program) was born EDVAC make up of calculator, logic control unit, memory, input and output five major components, and described the five most of the functions and mutual relations in the 101 page report The era of electronic computer began.
