Alan Turing
Definition
English mathematician and logician (1912-1954).
Description
It took part, during the war, with the development of the Colossus machine which made it possible to decipher the messages of the German army. In 1936, it publishes "In connection with the calculable numbers". It that point reaches to a conclusion close to that of the logician Kurt Gödel the theoretical machine which it describes precedes the computers of which the first appear at the end of the Forties. It gives a definition of the concept of algorithm. In 1954, in "Intelligence and computers", it wonders whether the machines will have one day the capacity to think. To avoid launching out in one embarrassing definition of the thought, it proposes a "test": an observer communicates on the one hand with another man, on the other hand with a computer, separated from him, in another part. It can exchange information only by the intermédaire of a keyboard, without seeing them. Will the computer, programmed to be made pass for human, be able to deceive the observer? Turing thinks that it will be possible in the fifty years.
