Скачать или смотреть Why One Cambridge Nobody Built A 'Logic Machine' — And Saved 14 Million Lives

How did one mathematician's "impossible" machine read Hitler's most secret orders for four years—and why did German intelligence never realize their codes had been broken? In 1940, Alan Turing arrived at Bletchley Park with a design that violated every principle of traditional codebreaking: a machine that didn't guess at messages but eliminated wrong answers through pure logic. This is the untold story of the Bombe, the electromechanical device that tested thousands of Enigma rotor settings per minute and turned 159 quintillion possible combinations into readable intelligence in under 20 minutes.

Without Turing's machine, U-boats would have continued sinking 500 Allied ships every six months, Britain would have starved, and D-Day would have failed. Discover how Polish mathematicians cracked the first Enigma version in 1932, why the German Navy's added rotors made their breakthrough obsolete, how Turing rebuilt the concept into an industrial-scale operation with 200 machines working simultaneously, and why the Ultra intelligence they produced created a closed feedback loop that made Allied deception operations undetectable. From convoy survival rates that jumped from 40% to 85% once Naval Enigma was broken, to the strategic intelligence that kept Hitler's Fifteenth Army frozen at Calais for seven weeks after D-Day, this is how one Cambridge mathematician's forbidden logic machine shortened World War II by an estimated two years—and why he died in obscurity just eleven years later while his greatest achievement remained classified until 1974.
