Showing results for "Enigma" in Military

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.

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.

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.

A gripping tale of betrayal and counterbetrayal that tells the story of the most enigmatic member of the Cambridge spy ring - Donald Maclean. Donald Maclean was a star diplomat, an establishment insider and a keeper of some of the West's greatest secrets. He was also a Russian spy, driven by passionately held beliefs, whose betrayal and defection to Moscow reverberated for decades.

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.

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.

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.

According to Winston Churchill, Alan Turing made the single biggest contribution to the Allied victory over Nazi Germany with his code-breaking machine. The world is also indebted to Turing's genius for the modern computer. It was clear that Turing had a remarkable mind from an early age. He taught himself to read in just three weeks. At his first school, the headmistress said, "I have had clever and hardworking boys, but Alan has genius."

Fort Knox is one of those rare phrases that has escaped its physical boundaries and entered everyday language. It is spoken casually, often without thought, as a shorthand for something impenetrable, something absolute. To say that something is “as safe as Fort Knox” is to suggest that it is beyond reach, beyond threat, beyond question. Yet the reality behind this familiar expression is far more grounded, far more human, and far more structured than the myth allows. Fort Knox is not an ancient fortress shaped by centuries of siege and legend.

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.

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.

Hitler's U-boats rule the North Atlantic and threaten to eliminate the Allied supply lines through meticulously coordinated attacks using Germany's secret weapon: the Enigma. Desperate to turn the tide of the war, British scientists at Bletchley Park work tirelessly to break the codes. But there is a problem. They need the German ciphers and a working Enigma machine.

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.
