  2. Early history             He was born as Alan Mathison Turing on June 23rd 1912 inPaddington, London.(website)  Turing was highly educated. He attended Kings College, Cambridge in 1931 tostudy Mathematics.(website)Turing was known as a brilliant thinker. Apart from Mathematics, he also studiedPhilosophy, Psychology, Physics, Chemistry and Biology.(website)His personality was to have something cool to work with that has to do withmachines.(website)But he was more interested in deeper understanding of how computer works and thefuture of computers.(website)

  3. Early HistoryInetellectually, Turing was an happy man but personally, he was sad.He was homosexual and during his time homosexuality relationship was a crime andtherefore illegal.(website)So he had an alternative to take female hormones to avoid going toprison.(website)But he was at big risk with his personal life.

  4. Early HistoryIn 1937, after Turing graduated from Cambridge studying Mathematics in 1934 hewrote a famous paper: "On Computable Numbers" with an application to the"Entscheidungsproblem", which postulated the Turing Machine.(website)The Turing Machine was later useful during the war. (website)

  5. The EntscheidungsproblemThe Entscheidungsproblem was published by Alonzo Church and Alan Turing in 1936- 1937  to further describe the work of David Hilbert's challenge problem.(Theman who knew too much)The Entscheidungsproblem is commonly referred to by its original German name,which means "decision problem"(The man who knew too much)Entscheidungsproblem is a concept of a mathematical algorithm, an arithmeticstatement that can be either true or false. (website)The Entscheidungsproblem idea introduced the concept of the Turing machine. Andlatter was computable with the Turing machine(website).

  6. The EntscheidungsproblemBy this problem, Hilbert meant that within that system, any true statement couldbe formally proven and any false statement could be disproven. ( The Man whoknew too much) (The man who knew too much)He meant that, within the system, no invalid statement, such as 2+2 = 5 or 1 =0, could be arrived at through a valid process. (The man who knew too much)Simply meaning, within that system, there could be shown to be a "definitemethod" by means of which the truth or falsity of any statement might beascertained. (The man who knew too much)

  7. The Entscheidungsproblem In the 1930's when he began his work on the Entscheidungsproblem, the word"computer" had a different meaning from todays meaning. It meant someone whodid computations. (The man who knew too much)Because in the1930's computations took long hour of human labor in which today'ssimple addition problem's  was solved using Charles Babbage abacus which laterplayed a big influence in the invention of Turing's "universal machine"(The manwho knew too much)

  8. The Turing MachineWith the influence of the Entscheidungsproblem and Charles Babbage abacus,Turing invented a machine named the Turing machine which was used to performspecific algorithm and simple arithmetic problems like 2 + 2 (The man who knewtoo much)

  9. The Turing Machine and how it works.Each number was represented in Binary system. (The man who knew too much)The machine was divided into 4 columns.  (The man who knew too much)The first column is the m-configuration lettered from A - D, the second columnis for symbol which is left blank. And the third column is where the action ofthe algorithm takes place. Lastly, the fourth column is the New m-configurationwhich prints the answers. (The man who knew too much)

  10. Later in the years, an advanced set of the machines was made which workedbetter. They still did the same thing but it was more advanced than the firstset of machines. (78, the man who knew too much)The newest machines at that time later performed derivatives and differentiationproblems (78, the man who knew too much)

  11. The Bombe Machine (1939 - 45)The day after the war broke out Turing "joined up" full time at the GovernmentCode and Cypher School, which had just moved to Bletchley Park. He was in thefirst handful of the stream of able mathematicians drafted into theircode-breaking operations. (website)In the next three years Turing was the key figure in the continual battle todecode messages encrypted by the increasingly complex Enigma machines, usingthe 'Bombe' machine

  12. The Bombe was an electro-mechanical device, developed by Turing with help fromanother mathematician W. G. Welchman, inspired by the Polish 'Bomba'. Theperiods when the Naval code could be broken saw dramatic reductions in theshipping losses from the Atlantic convoys so essential to the conduct of theAllied war effort. (website)

  13. The Bombe MachineBy the time Turing returned to the U.K., the ability to decode had beenrestored, under his deputy, and his deputy remained in charge. Turing moved onto a general consultancy role, and to work on a Speech Secrecy system. TheAmerican system comprised three roomfuls of equipment (one each for the WhiteHouse, Pentagon and Whitehall), and Turing thought up a much smallerelectro-mechanical device, about the size of a typewriter, which wouldobviously make the facility more widely available! (website)

  14. Honours In 1945, he was awarded the O.B.E for his contribution in the war(website)In 1951, he was elected a Fellow of the Royal Society (website)

  15. Final Years of Turing and His LegacyAfterwards his personal life caught up with him. In june 1954, he died fromcyanide poisoning, with a verdict concluding suicides the cause; though he didlegitimately have cyanide in the house in connection with chemical experiments.(Website).

  16. ApologyIn September 2009, PM Gordon Brown announced a sincere apology for themistreatment of Alan Turing, the World War II code breaker, for being gay.(bbc)Slide 16 ACM Turing Award.Today, He is well know for his brilliant contribution to computer and nowindividuals receive an award in honour of him called the ACM Turing ward.
