Alan Turing, Enigma ist die Biographie des legendären britischen Mathematikers, Logikers, Kryptoanalytikers und Computerkonstrukteurs Alan Mathison Turing (1912-1954). Turing war einer der bedeutendsten Mathematiker dieses Jahrhunderts und eine höchst exzentrische Persönlichkeit. Er gilt seit seiner 1937 erschienenen Arbeit "On Computable Numbers", in der er das Prinzip des abstrakten Universalrechners entwickelte, als der Erfinder des Computers. Er legte auch die Grundlagen für das heute "Künstliche Intelligenz" genannte Forschungsgebiet. Turings zentrale Frage "Kann eine Maschine denken?" war das Motiv seiner Arbeit und wird die Schlüsselfrage des Umgangs mit dem Computer werden. Die bis 1975 geheimgehaltene Tätigkeit Turings für den britischen Geheimdienst, die zur Entschlüsselung des deutschen Funkverkehrs führte, trug entscheidend zum Verlauf und Ausgang des Zweiten Weltkriegs bei.

The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley Alan Turing was the mathematician whose cipher-cracking transformed the Second World War. Taken on by British Intelligence in 1938, as a shy young Cambridge don, he combined brilliant logic with a flair for engineering. In 1940 his machines were breaking the Enigma-enciphered messages of Nazi Germany’s air force. He then headed the penetration of the super-secure U-boat communications. But his vision went far beyond this achievement. Before the war he had invented the concept of the universal machine, and in 1945 he turned this into the first design for a digital computer. Turing's far-sighted plans for the digital era forged ahead into a vision for Artificial Intelligence. However, in 1952 his homosexuality rendered him a criminal and he was subjected to humiliating treatment. In 1954, aged 41, Alan Turing took his own life.

The official book behind the film, The Imitation Game, this is a dramatic portrayal of the life and work of Alan Turing, one of Britain's most extraordinary unsung heroes, and one of the world's greatest innovators. This is the official story that has inspired the British film, The Imitation Game, a nail-biting race against time following Alan Turing, the pioneer of modern-day computing and credited with cracking the German Enigma code, and his brilliant team at Britain's top-secret code-breaking centre, Bletchley Park, during the darkest days of World War II. Turing, whose contributions and genius significantly shortened the war, saving thousands of lives, was the eventual victim of an unenlightened British establishment, but his work and legacy live on. Prime Minister Gordon Brown released a statement of apology in 2009 on behalf of the British government for the "appalling" treatment of Turing.

Not only was Turing one of the founders of computer science, he also helped the British military break Nazi codes, allowing them to decipher messages that helped the Allies win World War II. Turing was a pioneer in the field of artificial intelligence; he developed the Turing test, which determines whether a machine is capable of intelligence like that of a human being. Despite his impressive list of accomplishments, Turing was persecuted for his homosexuality. Sidebars offer extra information about topics such as Bletchley Park, ciphers, and the times Turing lived in, while a timeline serves as a quick reference for the chronology of key events in Turing’s life.

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.' In 1954, he was found dead, poisoned by an apple laced with cyanide. This is the story of his life.

England, 1954, der kalte Krieg hält die Welt in seinem eisernen Griff - und im kleinen Städtchen Wilmslow wird ein Mann tot aufgefunden. Es ist der Mathematiker Alan Turing, neben seinem Bett liegt ein mit Zyankali versetzter Apfel, alles deutet auf Selbstmord hin. Hat Turing die Repressionen nicht mehr ertragen, unter denen er als Homosexueller zu leiden hatte? Oder hat sein Tod doch etwas mit seiner Arbeit für den Geheimdienst während des 2. Weltkriegs zu tun? Der junge Detective Sergeant Leonard Corell, selbst einst ein vielversprechender Mathematiker, hegt den Verdacht, dass höhere Mächte ihre Finger im Spiel haben. Gegen Widerstände beginnt er, die Teile eines Puzzles zusammenzusetzen, das vielleicht eines der am besten gehüteten Geheimnisse des Kriegs offenbart.

Er is niet veel overdreven aan de stelling dat de Britse wiskundige Alan Turing de geallieerden heeft gered in hun strijd tegen de Nazi's, dat hij de uitvinder was van de computer, de bedenker van kunstmatige intelligentie en een voorloper in de strijd om vrijheid voor homoseksuelen - en dat alles voordat hij, 41 jaar oud, zelfmoord pleegde. Deze schitterende biografie vertelt het definitieve verhaal van een uitzonderlijk genie en een even uitzonderlijk leven. Alan Turings grote kracht was zijn briljante analytische geest gecombineerd met zijn gave voor het ontwerpen van 'intelligente' machines. In 1940 wist hij met zijn vindingen de Duitse Enigma-code te kraken - de code waarmee de Duitse lucht- en zeemacht alle communicatie beveiligde. Hij bracht er het Duitse oorlogscommando een slag mee toe die de oorlog bekortte en vele mensenlevens redde. Het was niet Turings enige wapenfeit. Al voor de oorlog werkte de briljante wiskundige aan het concept van een universele machine, een idee dat hij in 1945 uitwerkte tot de allereerste digitale computer. In 1952 kwam een abrupt einde aan de glansrijke carrière van Alan Turing, toen hij door de autoriteiten werd opgepakt wegens homoseksualiteit, een strafbaar feit dat in die tijd nog actief werd vervolgd. In het land dat hij zes jaar lang in het belang van de vrijheid had gediend, volgde een veroordeling en een mensonterende behandeling. In 1954 pleegde Alan Turing, 41 jaar oud, zelfmoord. Alan Turing, het Enigmaverscheen voor het eerst in 1983 en kreeg een glorieuze ontvangst. Enkele jaren geleden volgde een herziene editie, ingeleid door Douglas Hofstadter.

Alexander, Tommy Flowers, Harry Golombek, Ralph Tester. Extracto: Enigma era el nombre de una maquina que disponia de un mecanismo de cifrado rotatorio, que permitia usarla tanto para cifrar como para descifrar mensajes. Varios de sus modelos fueron muy utilizados en Europa desde inicios de los anos 1920. Su fama se debe a haber sido adoptada por las fuerzas militares de Alemania desde 1930. Su facilidad de manejo y supuesta inviolabilidad fueron las principales razones para su amplio uso. Su sistema de cifrado fue finalmente descubierto y la lectura de la informacion que contenian los mensajes supuestamente protegidos es considerado, a veces, como la causa de haber podido concluir la Segunda Guerra Mundial al menos dos anos antes de lo que hubiera acaecido sin su descifrado. La maquina equivalente britanica, Typex, y varias americanas, como la SIGABA (o M-135-C en el ejercito), eran similares a Enigma. La primera maquina moderna de cifrado rotatorio, de Edward Hebern, era considerablemente menos segura, hecho constatado por William F. Friedman cuando fue ofrecida al gobierno de Estados Unidos. La maquina Enigma era un dispositivo electromecanico, lo que significa que usaba una combinacion de partes mecanicas y electricas. El mecanismo estaba constituido fundamentalmente por un teclado similar al de las maquinas de escribir cuyas teclas eran interruptores electricos, un engranaje mecanico y un panel de luces con las letras del alfabeto. La parte electrica consistia en una bateria que se conecta a una de las lamparas, que representan las diferentes letras del alfabeto. Se puede observar en la parte inferior de la imagen adjunta el teclado, siendo las lamparas los minusculos circulos que aparecen encima de este. El corazon de la maquina Enigma...

Alan Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight. An introduction by leading Turing expert Jack Copeland provides the background and guides the reader through the selection. About Alan Turing Alan Turing FRS OBE, (1912-1954) studied mathematics at King's College, Cambridge. He was elected a Fellow of King's in March 1935, at the age of only 22. In the same year he invented the abstract computing machines - now known simply as Turing machines - on which all subsequent stored-program digital computers are modelled. During 1936-1938 Turing continued his studies, now at Princeton University. He completed a PhD in mathematical logic, analysing the notion of 'intuition' in mathematics and introducing the idea of oracular computation, now fundamental in mathematical recursion theory. An 'oracle' is an abstract device able to solve mathematical problems too difficult for the universal Turing machine. In the summer of 1938 Turing returned to his Fellowship at King's. When WWII started in 1939 he joined the wartime headquarters of the Government Code and Cypher School (GC&CS) at Bletchley Park, Buckinghamshire. Building on earlier work by Polish cryptanalysts, Turing contributed crucially to the design of electro-mechanical machines ('bombes') used to decipher Enigma, the code by means of which the German armed forces sought to protect their radio communications. Turing's work on the version of Enigma used by the German navy was vital to the battle for supremacy in the North Atlantic. He also contributed to the attack on the cyphers known as 'Fish'. Based on binary teleprinter code, Fish was used during the latter part of the war in preference to morse-based Enigma for the encryption of high-level signals, for example messages from Hitler and other members of the German High Command. It is estimated that the work of GC&CS shortened the war in Europe by at least two years. Turing received the Order of the British Empire for the part he played. In 1945, the war over, Turing was recruited to the National Physical Laboratory (NPL) in London, his brief to design and develop an electronic computer - a concrete form of the universal Turing machine. Turing's report setting out his design for the Automatic Computing Engine (ACE) was the first relatively complete specification of an electronic stored-program general-purpose digital computer. Delays beyond Turing's control resulted in NPL's losing the race to build the world's first working electronic stored-program digital computer - an honour that went to the Royal Society Computing Machine Laboratory at Manchester University, in June 1948. Discouraged by the delays at NPL, Turing took up the Deputy Directorship of the Royal Society Computing Machine Laboratory in that year. Turing was a founding father of modern cognitive science and a leading early exponent of the hypothesis that the human brain is in large part a digital computing machine, theorising that the cortex at birth is an 'unorganised machine' which through 'training' becomes organised 'into a universal machine or something like it'. He also pioneered Artificial Intelligence. Turing spent the rest of his short career at Manchester University, being appointed to a specially created Readership in the Theory of Computing in May 1953. He was elected a Fellow of the Royal Society of London in March 1951 (a high honour).

Alan Turing's fundamental contributions to computing led to the development of modern computing technology, and his work continues to inspire researchers in computing science and beyond. This book is the definitive collection of commemorative essays, and the distinguished contributors have expertise in such diverse fields as artificial intelligence, natural computing, mathematics, physics, cryptology, cognitive studies, philosophy and anthropology. The volume spans the entire rich spectrum of Turing's life, research work and legacy. New light is shed on the future of computing science by visionary Ray Kurzweil. Notable contributions come from the philosopher Daniel Dennett, the Turing biographer Andrew Hodges, and the distinguished logician Martin Davis, who provides a first critical essay on an emerging and controversial field termed hypercomputation. A special feature of the book is the play by Valeria Patera which tackles the scandal surrounding the last apple, and presents as an enigma the life, death and destiny of the man who did so much to decipher the Enigma code during the Second World War. Other chapters are modern reappraisals of Turing's work on computability, and deal with the major philosophical questions raised by the Turing Test, while the book also contains essays addressing his less well-known ideas on Fibonacci phyllotaxis and connectionism.
