A century apart: 1837 - Analytical Engine 1936 - Turing Machine "[Charles Babbage's] Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as *Turing-complete.* In other words, the logical structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era." [ https://en.wikipedia.org/wiki/Analytical_Engine ] Turing sort of picked up where Babbage left off 100 years before. In retrospect, it is surprising that programming languages (which also logicians seemed oblivious to as well as mathematicians) took so long to originate. - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
