Resultados para "Enigma" en Guerras y conflictos

A estas alturas nadie puede poner en duda que la Segunda Guerra Mundial es una fuente inagotable de historias. Las complicadas operaciones militares, el elevado número de soldados y aparatos de guerra implicados, los estudios científicos destinados a revolucionar las infraestructuras bélicas o las herméticas teorías nazis, nos han dejado no pocos acontecimientos que aún hoy están sin responder.

For almost four desperate years between 1939 and 1943, British and American navies fought a savage, losing battle against German submarine wolf packs. The Allies might never have turned the tide of that historic battle without an intelligence coup. The race to break the German U-boat codes is one of the last great untold stories of World War II.

Enigma est une machine électromécanique portable servant au chiffrement et au déchiffrement de l'information. Elle fut inventée par l'Allemand Arthur Scherbius, reprenant un brevet du Néerlandais Hugo Koch, datant de 1919. Son utilisation la plus célèbre fut celle faite par l'Allemagne nazie et ses alliés, avant et pendant la Seconde Guerre mondiale, la machine étant réputée inviolable selon ses concepteurs.

In less than six hours in August 1942, nearly 1,000 British, Canadian, and American commandos died in the French port of Dieppe in an operation that, for decades, seemed to have no real purpose. Canadian historian David O’Keefe uses hitherto classified intelligence archives to prove that this catastrophic and apparently futile raid was, in fact, a mission set up by Ian Fleming of British Naval Intelligence as part of a “pinch” policy designed to capture material relating to the four-rotor Enigma Machine.

The Enigma cipher was supposed to be the German's impenetrable defence for its military communications against prying eyes during World War II. All manner of secrets were entrusted to it. When the Allies finally managed to crack the code, it heralded a turning point in the war.

When the ashes had settled after World War II and the Allies convened an international war crimes trial in Nuremberg, a psychiatrist, Douglas Kelley, and a psychologist, Gustave Gilbert, tried to fathom the psychology of the Nazi leaders using extensive psychiatric interviews, IQ tests, and Rorschach inkblot tests. Never before or since has there been such a detailed study of governmental leaders who orchestrated mass killings.

There are a wealth of conspiracies surrounding World War II, from covert assassinations to outlandish secret missions and shocking cover-ups. Intelligence agencies practiced stunning deceptions and disinformation was spread widely, but what truths lie beneath these elaborate theories? Military historian Alexander Macdonald examines the evidence.

Alan Mathison Turing was a mathematician, computer system researcher, scholar, cryptanalyst, thinker, and theoretical biologist from the U.K. With the Turing device, which can be considered a design of a general-purpose computer system, Turing had a substantial influence on the development of theoretical computer technology, offering a formalization of the ideas of algorithm and calculation. Turing is considered the creator of theoretical computer technology and AI.

The justification for the atomic bomb was simple: it would defeat Hitler and end the Second World War faster, saving lives. The reality was different. Fallout dismantles the conventional story of why the atom bomb was built. Peter Watson has found new documents showing that long before the...

Alan Mathison Turing. Mathematician, philosopher, codebreaker, a founder of computer science, and the father of Artificial Intelligence, Turing was one of the most original thinkers of the last century - and the man whose work helped create the computer-driven world we now inhabit. But he was also an enigmatic figure, deeply reticent yet also strikingly naive. Turing's openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely death at the age of only 41.

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army...
