Do not be afraid of its size, this book is not a novel, and can be read many times. But above all, it would be unfortunate to miss, as it will enrich you. For it is not a math book or a book of philosophy, but a single work, sometimes tote, popularizer say pedants, which addresses complex topics simply and malice. Drawing on the works of Bach, very structured, the drawings of Escher, very tortured and Gödel's theorem, very amazing, Douglas Hofstadter leads us into his thoughts on the world, artificial intelligence ...
Let yourself be taken by its enigma MU MIU (I spent hours trying to solve the system, refusing to believe his impossibility), let yourself be attracted by strange attractors ... then you'll love to read many passages, even years after, even by finding that certain concepts have aged (the book dates from 1979)!
Intelligence is the appointment and this book will give you some keys, or rather a few strands of garland Eternal!
