Dan, did not the English expand on the work performed with the drum style computer developed by the Polish cryptographers? I am in no way devaluing the work of Turing & the people at Bletchley, but the Poles originally broke the cyphers. Then, I believe, the Germans made some improvements, including one or two more rotors, etc., and then the Poles lost the ability to continue decoding the Enigma cyphers. But, I believe their bomba was essentially refined and up- graded by Turing. 73, lh On 6/23/2012 4:11 PM, Daniel Holmes wrote:
Yeah, its a simple Turing machine.
Turing was a fascinating man. He invented the bombe, the machine used to break the enigma code during world war 2, and is considered the father of artificial intelligence with his Turing tests. He was a brilliant mathematician and cryptographer.
Turing machines are a hypothetical computational machine that help to understand the limits of mechanical computational algorithms. Turing tests are tests given to humans that try to have the human distinguish the answers given by a machine as indistinguishable from an humans answers. Basically to see how far we can go with artificial intelligence.
I've always wondered what modern computer science would look like if he hadn't committed suicide in his early forties.

Hi Chuck,
I don't think the image on the page is supposed to be a slide rule. Turing's device used a paper tape and I think that's what they are trying to show..

I get the impression that nobody on the Google staff has ever used a slide rule.
