Interested in the story of Alan Turing, his psychology and his discoveries, I was very disappointed .... Not only this book brings nothing new, but in addition he misses what he wrote especially when he speaks of computer ... - A computer is composed of 3 parts: memory execution unit and control unit .... This description may seem commonplace today, says the author. Oh, the control unit? I knew the arithmetic logic unit, ALU, but the control unit? When Alan Turing speaks library, it simply speaks of indexation, that are not faced when author. As well as artificial intelligence, which reasons in the form of deduction rules and not of calculation rules. When the therapist, it can be wrong ... So I would be more forgiving, but to suggest that Alan Turing was running for the pleasure of the body because he was gay, it's push the envelope a little further. Besides the statements that I find stupid like "we spend our lives to invent his death." In short, I agree with previous comments.
