The birth of digital

摘要

Secrecy and computers have always been intertwined. Developed during the fraught years of the second world war, details of the efforts to build Colossus, the British machine that helped decrypt Nazi messages, were kept close to the chests of the Allies. In Turing's Cathedral, science historian George Dyson shines light on the critical period when computers came into being. He begins with British mathematician Alan Turing's famous 1936 description of a machine designed to resolve a problem in mathematical logic.
