A biography of alan turing one of the great pioneers of the computer world

Alan Turing's interest in science began early and never wavered. Both at his preparatory schools and later at Sherborne, which he entered inthe contrast between his absorbed interest in science and mathematics, and his indifference to Latin and "English subjects," perplexed and distressed his teachers, bent on giving him a well-balanced education. Many of the characteristics that were strongly marked in his later life can already be clearly seen in remembered incidents of this time: In he entered King's College, Cambridge, as a mathematical scholar.

The earliest substantial work in the field of artificial intelligence was done in the midth century by the British logician and computer pioneer Alan Mathison Turing.

In Turing described an abstract computing machine consisting of… Early life and career The son of a civil servant, Turing was educated at a top private school. He entered the University of Cambridge to study mathematics in Later that year Turing moved to Princeton University to study for a Ph.

The Entscheidungsproblem sought an effective method for solving the fundamental mathematical problem of determining exactly which mathematical statements are provable within a given formal mathematical system and which are not.

A method for determining this is called a decision method. In Turing and Church independently showed that, in general, the Entscheidungsproblem problem has no resolution, proving that no consistent formal system of arithmetic has an effective decision method.

In fact, Turing and Church showed that even some purely logical systems, considerably weaker than arithmetic, have no effective decision method. It was in the course of his work on the Entscheidungsproblem that Turing invented the universal Turing machine, an abstract computing machine that encapsulates the fundamental logical principles of the digital computer.

The claim is important because it marks out the limits of human computation. Church in his work used instead the thesis that all human-computable functions are identical to what he called lambda-definable functions functions on the positive integers whose values can be calculated by a process of repeated substitution.

A few weeks previously, the Polish government had given Britain and France details of the Polish successes against Enigmathe principal cipher machine used by the German military to encrypt radio communications. The Bomba depended for its success on German operating procedures, and a change in those procedures in May rendered the Bomba useless.

During the autumn of and the spring ofTuring and others designed a related, but very different, code-breaking machine known as the Bombe.

For the rest of the war, Bombes supplied the Allies with large quantities of military intelligence. By early the cryptanalysts at Bletchley Park were decoding about 39, intercepted messages each month, a figure that rose subsequently to more than 84, per month—two messages every minute, day and night.

His design for the Automatic Computing Engine ACE was the first complete specification of an electronic stored-program all-purpose digital computer. Discouraged by the delays at NPL, Turing took up the deputy directorship of the Computing Machine Laboratory in that year there was no director.

His earlier theoretical concept of a universal Turing machine had been a fundamental influence on the Manchester computer project from the beginning. He also wrote the first-ever programming manual, and his programming system was used in the Ferranti Mark Ithe first marketable electronic digital computer Artificial intelligence pioneer Turing was a founding father of artificial intelligence and of modern cognitive science, and he was a leading early exponent of the hypothesis that the human brain is in large part a digital computing machine.

Last years Turing was elected a fellow of the Royal Society of London in Marcha high honour, yet his life was about to become very hard. Turing spent the remainder of his short career at Manchester, where he was appointed to a specially created readership in the theory of computing in May From Turing had been working on what is now known as artificial life.

The official verdict was suicide, but no motive was established at the inquest. In fact, his mental state appears to have been unremarkable at the time. Although suicide cannot be ruled out, it is also possible that his death was simply an accident, the result of his inhaling cyanide fumes from an experiment in the tiny laboratory adjoining his bedroom.

Nor can murder by the secret services be entirely ruled out, given that Turing knew so much about cryptanalysis at a time when homosexuals were regarded as threats to national security.How influential was Alan Turing? The tangled invention of computing (and its historiography) involved in the great British Enigma code-breaking effort that deserves at least some credit for the Allied victory in World War II, and widely considered to be the first digital computer).

But one could argue that this is also the case with the. Biography.

Alan Turing Essay - Alan Mathison Turing was undoubtedly one of the greatest pioneers of our computer world. We can clearly label him the founder of what we know today as modern computer science, but beyond that, he was also a great mathematician, a code-breaker, philosopher, and certainly a risk-taker.
