Origins of Computing: The “Turing Box” • The First computers • Modern computers • The WIntel Box • The Mac • Where did it all come from? • Turing Machine • Alan Turing • The Father of Computer Science • British Intelligence • Created First electronic “Computer”
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
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.
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
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
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
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).
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
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
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
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.
Alan Turing: Creator of the Computer • End of Turing Presentation
