life
n. 1. A cellular-automata game invented by John Horton Conway and first
introduced publicly by Martin Gardner ( Scientific American , October 1970);
the game's popularity had to wait a few years for computers on which it
could reasonably be played, as it's no fun to simulate the cells by hand.
Many hackers pass through a stage of fascination with it, and hackers at
various places contributed heavily to the mathematical analysis of this game
(most notably Bill Gosper at MIT, who even implemented life in TECO !). When
a hacker mentions life , he is much more likely to mean this game than the
magazine, the breakfast cereal, or the human state of existence. Many web
resources are available starting from the Open Directory page of Life. The
Life Lexicon is a good indicator of what makes the game so fascinating. A
glider, possibly the best known of the quasi-organic phenomena in the Game
of Life. 2. The opposite of Usenet.
