X, Y & Z describes how French, British and Polish secret services came together to unravel the Enigma machine. It tells of how, under the very noses of the Germans, Enigma code-breaking continued in Vichy France. And how code-breakers from Poland continued their work for Her Majesty’s Secret Service, watching the USSR’s first steps of the Cold War.
The Story of Computing explores the history of the technology from the first attempts to use mjachines to solve mathematical problems to the IT which now pervades everyday life. Featuring eccentric and flamboyant personalities, brilliant discoveries, and fascinating insights into how computing has changed our world, this is the essential guide to a subject that none of us can ignore.
Alan Turing was an extraordinary man who crammed into a life of only 42 years the careers of mathematician, codebreaker, computer scientist and biologist. He is widely regarded as a war hero grossly mistreated by his unappreciative country and it has become hard to disentangle the real man from the story. It is easy to cast him as a misfit, the stereotypical professor. But actually Alan Turing was never a professor, and his nickname ‘Prof’ was given by his codebreaking friends at Bletchley Park.
Alan Turing was an extraordinary man who crammed into a life of only 42 years the careers of mathematician, codebreaker, computer scientist and biologist. His codebreaking work at Bletchley Park was so significant it helped to shorten the Second World War, and with Tommy Flowers he built the first computer.
A man ahead of his time, many of his theories and calculations are still relevant today.
On 4th September, 1939 Alan Turing reported for duty at the Government Code & Cypher School at Bletchley Park. in 1939 the immediate challenge was to find a way to read messages enciphered on the Enigma machine. Together with another mathematician, Gordon Welchman, Alan Turing designed a new type of machine, the Bombe, which would give the codebreakers a breach in the security wall constructed by the Enigma.
This book explains the basics of the Bombe’s design and how it helped with the cracking of Enigma messages.
