Alan Turing was one of the most influential thinkers of the 20th century. In 1935, aged 22, he developed the mathematical theory upon which all subsequent stored-program digital computers are modeled. At the outbreak of hostilities with Germany in September 1939, he joined the Goverment Codebreaking team at Bletchley Park, Buckinghamshire and played a crucial role in deciphering Engima, the code used by the German armed forces 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' which were used by the German High Command for the encryption of signals during the latter part of the war. His contribution helped to shorten the war in Europe by an estimated two years. After the war, his theoretical work led to the development of Britain's first computers at the National Physical Laboratory and the Royal Society Computing Machine Laboratory at Manchester University. Turing was also a founding father of modern cognitive science, theorizing that the cortex at birth is an 'unorganized machine' which through 'training' becomes organized 'into a universal machine or something like it' He went on to develop the use of computers to model biological growth, launching the discipline now referred to as Artificial Life. The papers in this book are the key works for understanding Turing's phenomenal contribution across all these fields. The collection includes Turing's declassified wartime 'Treatise on the Enigma'; letters from Turing to Churchill and to codebreakers; lectures, papers, and broadcasts which opened up the concept of AI and its implications; and the paper which formed the genesis of the investigation of Artifical Life.

Paperback. Etat : Fine. Two listing notes: this is principally a collection of writings by Alan Turing , edited and introduced by B. Jack Copeland , rather than a book solely by Copeland. Also, Oxford records ISBN 9780198250807 as the paperback edition first published in 2004 ; your copy may be a 2013 reprint, so the impression page should settle the date. Alan Turing helped invent theoretical computer science before electronic computers properly existed, played a decisive role in breaking German codes during the Second World War, designed an early stored-program computer, helped establish artificial intelligence and proposed a mathematical explanation for patterns in living organisms. He accomplished this before dying at forty-one, leaving subsequent generations the comparatively modest task of building the world he had already imagined. The Essential Turing brings together his most important writings across mathematics, logic, computing, philosophy, codebreaking, artificial intelligence and artificial life. Edited by leading Turing scholar B. Jack Copeland, it allows readers to encounter Turing?s ideas in his own words, assisted by introductions and explanatory guides for those who do not ordinarily begin the day contemplating the limits of computability. The collection includes Turing?s celebrated 1936 paper on computable numbers. In addressing a difficult problem in mathematical logic, he imagined an abstract machine that reads and writes symbols according to precise rules. The ?Turing machine? was not a physical device awaiting a manufacturer; it was a conceptual model showing what computation itself means. Modern computers are vastly more colourful, expensive and prone to requesting software updates, but the underlying principle remains recognisably his. His universal machine introduced the idea that one machine could perform any computational task if supplied with the correct instructions. Hardware and program could therefore be separated, allowing the same machine to calculate, process text, play games or display advertisements for items discussed privately five minutes earlier. Turing supplied the profound intellectual foundation; commercial civilisation attended to the refinements. The book does not avoid the more demanding mathematics. Papers on logic, ordinal systems and computability show Turing working at the frontiers of formal thought, asking what can be calculated and whether some problems lie permanently beyond mechanical solution. Copeland?s commentary provides routes into this material, although readers may still occasionally discover that Turing has crossed an intellectual mountain while they are checking the map legend. A major section concerns Enigma and Turing?s secret wartime work at Bletchley Park. As a leading member of Hut 8, he developed methods for attacking German naval Enigma communications and helped design procedures used with the cryptanalytic bombe machines. The battle of the Atlantic was fought by ships and submarines, but also by mathematicians examining letter patterns in Buckinghamshire. Included are declassified materials relating to Enigma, together with correspondence and accounts of the codebreaking campaign. These reveal that breaking a cipher was not a single dramatic moment after which every German message became politely readable. Keys changed, procedures varied and analysts had to exploit repeated habits, technical weaknesses and the occasional assistance of an operator who had become bored with following instructions. The volume also presents Turing?s post-war work on electronic computing. His design for the Automatic Computing Engine anticipated important features of high-speed stored-program computers. Government committees responded with the timeless institutional method of recognising a revolutionary proposal and then discussing it until somebody elsewhere built something. Turing?s 1950 paper ?Computing Machinery and Intelligence? asks whether machines can think. Rather than becoming trapped in de. N° de réf. du vendeur 7033
