Turing's Cathedral: The Origins of the Digital Universe, George Dyson
Alan Turing's contributions to science and computers are beyond doubt. His work on information technology, cryptography, and logic is still echoing today (especially around the Turing Machine and intelligent agents). Dyson does more than just tell the story of Turing. The book shares the eco–system Turing lived and worked within. It reinforces the value in polymathic thinking, and tells the story of other statisticians, biologists and logicians. Those insights are surprisingly valuable in today's context, as a lot of those problems dealt with in the early days of computing are still unsolved.
