Sometimes people that nothing of itself presented do what nobody could imagine.(Alan Turing)How does a computer think?How to find an error in the system in that they are not present?How to break up a code that it is impossible to break up?Scientist-mathematician Alan Turing in text of work "About the calculated numbers", going out in 1936, proved that the universal method of establishment of truth was not present and can not be in mathematical science. Mathematics always will contain uncomplying to permission of task. On the base of this method a scientist worked out the so-called "Machine of Turing", becoming the prototype of the modern personal computer. In the days of Second world he created a дешифровальную machine that allowed to break up the code of "Энигмы", that changed all motion of Second world war. Alan Turing is considered exactly the founder of modern cybernetics and main theorist problems of artificial intelligence. In this book Алан Turing decrypts not only the methods, philosophy but also code of own life.There "always is an error. Herein there is all business. Without them existence of any system is impossible. A question is only in that, how to find" her.(Alan Turing)
