3. Origins of Computing: The “Turing Box” /Cont./  Alan Turing  Analysis of the man  Not a man of material.  Used a piece of rope as a belt.  Placed little importance upon wealth or social class.  Although, by birthright, was a member of the upper class.  He lived for scientific study and the search for truths.  From early youth, had a great understanding for science.  But.. Lethargic and lacked motivation because elementary education (although considered exceptional by most) was largely unchallenging to Turing.  Fixed everything  Stopwatch and jogging  Alan Turing  Analysis of the man  Not a man of material.  Used a piece of rope as a belt.  Placed little importance upon wealth or social class.  Although, by birthright, was a member of the upper class.  He lived for scientific study and the search for truths.  From early youth, had a great understanding for science.  But..

4. Origins of Computing: The “Turing Box” /Cont./  The Driving Force  1930: Became obsessed with Death of childhood friend Christopher Morcum  Determined to be the underlying motivation for all his future study.  1933: studied mathematical based reasoning, general analysis, quantum physics, logic (Cambridge).  1935: hypothesized about a method or process by which all mathematical questions could be decided or solved  Invented the “Definite Method”  Methodical Process focusing on the idea of something done mechanically based on a theoretical machine able to perform certain precisely defined operations on paper tape.  The Driving Force  1930: Became obsessed with Death of childhood friend Christopher Morcum  Determined to be the underlying motivation for all his future study.  1933: studied mathematical based reasoning, general analysis, quantum physics, logic (Cambridge).  1935: hypothesized about a method or process by which all mathematical questions could be decided or solved  Invented the “Definite Method”  Methodical Process focusing on the idea of something done mechanically based on a theoretical machine able to perform certain precisely defined operations on paper tape.

5. Origins of Computing: The “Turing Box” /Cont./  Developed this hypothesis in response to Hilbert’s Idea of Decidability. (one method for all ?’s)  Proved Hilbert wrong and created his own “Definite Method” Definition  1936 Turing’s discovery stolen by would-be fame seeker Alonzo Church  Church’s Theory, however, didn’t include procedural operations in the physical world (relied too heavily on math)  In other words, empirically-supported data  Developed this hypothesis in response to Hilbert’s Idea of Decidability.

6. Origins of Computing: The “Turing Box” /Cont./  The Turing Machine  Turing then worked in isolation to enhance he and Church’s earlier discoveries.  Result: Turing made a bridge between the logical and physical worlds, thought and action, which crossed conventional boundaries.  His work introduced concept of Turing Machine Idea  Infinite number of “Turing Machines” each based on its own algorithm or instructions  The Turing Machine  Turing then worked in isolation to enhance he and Church’s earlier discoveries.  Result: Turing made a bridge between the logical and physical worlds, thought and action, which crossed conventional boundaries.  His work introduced concept of Turing Machine Idea  Infinite number of “Turing Machines” each based on its own algorithm or instructions

Origins of Computing: The “Turing Box” /Cont./  The Turing Machine /Cont./  The Universal Turing Machine embodies essential principals of the computer.  Single machine which can be turned to any well defined task by being supplied with the appropriate program or set of instructions  The Turing Machine /Cont./  The Universal Turing Machine embodies essential principals of the computer.  Single machine which can be turned to any well defined task by being supplied with the appropriate program or set of instructions

8. Origins of Computing: The “Turing Box” /Cont./  The Turing Machine /Cont./  Computers in the modern sense did not exist in 1936.  Modern being the kinds of electronic technology we see today.  Invented Morphogenesis  Created first “Electronic Computer” or Turing Machine to cipher or decode messages (Bombe).  True to the “Universal” Turing Machine Concept  Machine would decode German war messages (Enigma).  The Turing Machine /Cont./  Computers in the modern sense did not exist in 1936.  Modern being the kinds of electronic technology we see today.  Invented Morphogenesis  Created first “Electronic Computer” or Turing Machine to cipher or decode messages (Bombe).  True to the “Universal” Turing Machine Concept  Machine would decode German war messages (Enigma).

9. Origins of Computing: The “Turing Box” /Cont./  The Turing Machine /Cont./  Hired by British Intelligence  Would eventually lead to mysterious demise  Wartime Encryption Center  Bombe vs.. German Enigma  Enigma Cipher Machine its was the original name  The return to Manchester University  Trouble on the home front  Homosexual relationship  Jail vs.. estrogen shots  The Turing Machine /Cont./  Hired by British Intelligence  Would eventually lead to mysterious demise  Wartime Encryption Center  Bombe vs..

10. Origins of Computing: The “Turing Box” /Cont./  The Turing Machine /Cont./  Suffered a great deal of ridicule from peers  Intense period of depression followed  Became an embarrassment to the British Gvt.  1954: died of cyanide poisoning  Apple (half eaten beside his bed)  Suicide?  Mysterious  The Turing Machine /Cont./  Suffered a great deal of ridicule from peers  Intense period of depression followed  Became an embarrassment to the British Gvt.  1954: died of cyanide poisoning  Apple (half eaten beside his bed)  Suicide?  Mysterious

11. Alan Turing: Creator of the Computer  Alan Turing  Father of Computer Science  Developed the Definite Method principle  Major contributor in WW2 Intelligence  Persecuted for his Sexuality  Killed by his Government

12. Alan Turing: Creator of the Computer  A Genius  Major Contributor to modern science. …And all because of a fascination with death and mind over matter.
