In a paper on computable numbers of 1936, Alan Turing presented a thought experiment describing a machine that, with an infinitely long tape it writes, reads and alters symbols. He postulated that this machine, with the correct minimal set of operations, could calculate anything that is computable, no matter the complexity. Trivial as it might look today, it was ground-breaking for the concepts it unveiled at its time, inspiring Mike Darvey to build his own with a few modern touches.
