Wiener, an American scientist and founder of cybernetics, 1894 was born in a Jewish family in Columbia, Missouri, USA. My father is a professor of linguistics at Harvard University. /kloc-At the age of 0/8, Wiener received two doctorates in mathematics and philosophy from Harvard University. He is famous for putting forward "cybernetics". 1940, wiener began to think about how computers work like brains, and he found similarities between them. Wiener thinks that computer is a system of information processing and information conversion. As long as the system can get data, the machine itself should be able to do almost anything. Moreover, the computer itself does not have to be composed of gears, wires, shafts, motors and other parts. To prove this point, a professor at MIT even made a simple working computer out of stones and toilet paper rolls.

In the letter 1940 to mathematician Bush, Wiener put forward several principles of modern computer design: (1) is not analog, but digital; (2) It is composed of electronic components with as few mechanical parts as possible; (3) using binary instead of decimal; (4) Memory calculation table; (5) store data in the computer. These principles are correct.
