Alan Turing was once essentially the most influential thinkers of the twentieth century. He created one of many first designs for a stored-program laptop and is commonly thought of to be the daddy of machine technological know-how and synthetic intelligence.
During international battle II, Turing labored for the govt. Code and Cypher institution at Bletchley Park, Britain's codebreaking centre, the place he was once chargeable for breaking German naval codes, together with the supposedly unbreakable Enigma code, and assisting the Atlantic convoys steer clear of German U-boat assaults. This paintings most likely shortened international struggle II by way of as much as 4 years, saving hundreds of thousands of lives.
This is the tale of the fantastic lifestyles and paintings of a British hero and one of many maximum thinkers of the 20 th century.

The more rotors being used to generate the coded message, the greater were the odds against the code being cracked. The Enigma code had become virtually unbreakable. 6 Bletchley Park So far, the battle between the Germans and the Poles to solve the Enigma code might seem to be just a clash of mathematicians battling for supremacy, trying to outdo one another in an intellectual game – a kind of super-chess. But, once war was declared in September 1939 between Germany and her enemies, especially Britain, it became a battle where millions of lives were at stake.
Unlike the conditions at Bletchley Park, where money and resources seemed always stretched and barely adequate, the code-breaking system in America swung into action. A factory in Ohio that had produced cash registers for NCR (the National Cash Register company) began building Bombes for the US Navy to Alan’s designs. The American Bombes were much faster than the British Bombes at Bletchley. One reason was that the drums used in the American machines to drive the rotors rotated at 1,725rpm, which was 34 times faster than the British Bombes.
The main problems with this machine were that the paper tapes often got out of sync, and that the paper often snapped. Max Newman, one of Alan’s former tutors at Cambridge, had looked at the problems affecting the Heath Robinson machine, and he and an electronics engineer called Tommy Flowers had designed and built their own version of the machine, which used patterns generated electronically rather than paper tape. Because of this it was able to process five thousand characters a second. Newman and Flowers called their machine Colossus.
