Alan Turing: Enigmatic

George Johnson writes in The New York Times:

Maybe it's because I already knew the story - about the tragic genius who revolutionized mathematics, helped the British crack secret Nazi codes and died after biting into a poisoned apple. Or maybe I was just in the mood for fiction. For some reason, about halfway through David Leavitt's short, readable life of Alan Turing, I put the book aside for a few days and turned instead to his most recent novel, "The Body of Jonah Boyd." It is actually a novel within a novel, ending with a self-referential twist that made me wonder whether Leavitt had been inspired by Turing's dizzying proof about undecidability in mathematics, in which a computer tries to swallow its own tail.

Turing was a fellow at King's College, Cambridge, in 1936, when he confronted what might be called the mathematician's nightmare: the possibility of blindly devoting your life to what, unbeknownst to anyone but God, is an unsolvable problem. If only there were a way to know beforehand, a procedure for sifting out and discarding the uncrackable nuts.
