John Conway's Game of Life
This game became widely known when it was mentioned in an article published by Scientific American in 1970. It consists of a collection of cells which, based on a few mathematical rules, can live, die or multiply. Depending on the initial conditions, the cells form various patterns throughout the course of the game.
While it is impossible to assign credit for the conception of Cybernetics to a single individual, certainly one of the people most responsible for its development and popularity as well as its theoretical shape was the mathematician Norbert Wiener (see Wiener, Norbert).
