John von Neumann: Multifaceted Genius Bixin Chen, COMP 1631, Winter 2011 “ There are two kinds of people in the world: Johnny von Neumann and the rest of us.”--Eugene Wigner, a Nobel Prize–winning physicist Outline • Background • Contributions ---Mathematics ---Nuclear Physics ---Economics ---Computer Science ---Influences • Conclusion Background • Nationalities: Hungarian American • 1903.12.181957.02.08 • Academic area: Mathematics, computer science, physics, politics, economics Mathematics Set theory ---deals with the fundamental concept of sets and functions ---used everywhere in Mathematics the Ratio of the Mean Square Successive Difference to the Variance Cellular Automation Is a decentralized computing model providing an excellent platform for performing complex computation with the help of only local information. Nuclear Physics • Quantum Mechanics ----- the nature of atomic particles and the laws that govern their actions • developing the "implosion lens" of high explosives --- compress the plutonium. Economics • Game Theory ---Minimax Theorem: Existence of a saddle-point solution to 2 person, zero sum games “Theory of Games and Economic Behavior” classic work upon which modern-day game theory is based. revolutionize economics used to analyze a host of real-world phenomena from arms races to optimal policy choices of presidential candidates Computer Architecture • Proposed “Electronic Discrete Variable Automatic Computer” (EDVAC) in 1950, including: ---Binary System ---stored program ---conditional control transfer ADVANTAGES OF BINARY-BASED CIRCUITRY The design of a computer that handled two digits instead of 10 was infinitely more simplified. Cost was reduced reliability improved Why is EDVAC important? Both the data and the program be stored in memory at the same time Programs could be changed with the same speed and ease as data Influences John Von Neumann Theory prize --- awarded annually to a scholar(s) who has made fundamental, sustained contributions to theory in operations research and the management sciences. IEEE John von Neumann Medal ---outstanding achievements in computer-related science and technology. The proposal laid out the concepts behind the modern electronic digital computer! Conclusion John von Neumann had great on: -Mathematics: -Physics -Computer Science -Economics Still, he has influences on science development, like IEEE John von Neumann Medal.
