Today is Alan Turing’s 100th birthday.
Mathematicians celebrate him above all for his trailblazing 1936 paper On computable numbers with an application to the Entscheidungsproblem [pdf], which remains a very readable and coherent account of his work.
Historians reflect on the heroic role he played in the cracking of the Enigma Code during WW2.
Artificial Intelligence researchers contemplate his work on neural networks and the challenge he posed in the Turing Test.
Civil liberties campaigners regret his persecution for homosexuality and mourn his tragic death.
