The same timelessness lies behind the central element of Alan Turing’s story: the universal machine of 1936, which became the general-purpose digital computer in 1945. The universal machine is the focal, revolutionary idea of Turing’s life, but it did not stand alone; it flowed from his having given a new and precise formulation of the old concept of algorithm, or mechanical process. He could then say with confidence that all algorithms, all possible mechanical processes, could be implemented on a universal machine. His formulation became known immediately as ‘the Turing machine’ but now it is impossible not to see Turing machines as computer programs, or software.
