  1. The Magic ofComputing Dr. Tom Way CSESI 2009Haverford College June 30, 2009 0000000100000010000100100000000100000011000000010000010000000001000000100001001000000001

  2. My Background • UM  Radio  TV  UD  SE  VU • Computer Science professor for 7 years • Graduate student for 8 years • Software engineer for 9 years • Hollywood writer for 10 years • Magician for 40 years (1969) CSESI 2009

  3. Focus • Focus on teaching you how to perform some of the tricks • Understand the learning process for acquiring new tricks • Rely on your creativity to link tricks to your specific teaching needs CSESI 2009

  4. Plan for the day • Using magic to teach • Art & Science behind magic • Learning magic tricks • Where to find out more CSESI 2009

  5. Proposed Schedule • 9-12 watch, learn, try • 12-1 lunch • 1-3:30 develop, practice, perform CSESI 2009

  6. Remedial Computer Science 101 Prof. Tom WaySection 1 Meeting: Today 9-9:30am

  7. 2s Complement • What is 2s Complement? • Negative binary integers • What is the algorithm? • Start: 000101 • Not: 111010 • Add 1: 111011 • Check our work: 000101 5 +111011-5 000000 0 CSESI 2009

  8. Search Algorithms • Find specific value (its index) in an array • Random search • Linear search • Binary search • Optimal search • Know what the optimal is helps us to judge how good our algorithm is CSESI 2009

  9. GUI Design Principles • Principle of metaphor • Borrow behaviors from familiar systems • Principle of user profiling • Know who your user is • Principle of coherence • Behavior should be internallyand externally consistent CSESI 2009

  10. Load Balancing • Example: 3 tasks of different lengths • How long will it take to perform the tasks simultaneously? • How could we get them done faster? • What is the fastest way to get them done? CSESI 2009

  11. Data Compression • Purpose is to squeeze the air out of data so it fits in a smaller space • Lots of ways to do this – depends on data • Lossless – decompressed = original • Lossy – some data is missing • Run length encoding – lots of repetition • Huffman – probabilistic data (Morse code) CSESI 2009

  12. And now, back to yourregularly scheduled program

  13. Using Magic to Teach • Not a short-cut to As, revolutionary idea, scientifically validated approach • Is another trick for a good educator’s bag of pedagogical tricks • A little KLA (Kinetic Learning Activities) • A little problem-based learning • A little example-based teaching • A little what-the? • It’s cheap – don’t have to buy toys, candy, spend massive time planning, etc. CSESI 2009

  14. What is going on? • Active Thinking – brain in high gear • Uniqueness – brain loves surprise • Coolness – popular, generates buzz • Anticipation – appealing, fun, engaging • Evolving – empirical? anecdotal! CSESI 2009

  15. Approach 1: Topic Driven • Pick an upcoming topic you will teach • Find a trick that fits • Learn the trick • Plan what to say • Practice • Perform it in class CSESI 2009

  16. Approach 2: Trick Driven • Pick a trick that you really like • Find an upcoming topic that fits • Learn the trick • Plan what to say • Practice • Perform it in class CSESI 2009

  17. Learning a trick • Read the description • Work through each step • Try it in front of a mirror • Practice it a couple times • Use it in class CSESI 2009

  18. Performing a trick • Natural is best • The overused “make it your own” applies • Attitude is important • NOT know-it-all, fooled you, try to figure this out – TURN OFF • YES check this out, I’m amazed too, enjoy it along with them CSESI 2009

  19. Art of Magic • Magician’s Code • Never reveal how trick is done • Never repeat trick for same group • Practice, practice, practice • Patter – what you say, story you tell • In our case, the patter will involvesome aspect of Computer Science CSESI 2009

  20. Science of Magic • Misdirection • Controlling the audience’s attention • Making them look where you want them to • THE secret of all magic • Concealment - hiding • Switching - replacing • Forcing – not a free choice CSESI 2009

  21. Categories of Tricks • Production • Vanish • Transposition • Penetration • Levitation • Mental • Escape CSESI 2009

  22. MASTER Principle • Movement – large conceals small • Angles – consider your angles • Surprise – don’t tip your hand • Thought – keep their brains busy • Eyes – look where you want them to look • Reason – has to make sense CSESI 2009

  23. Let’s try it

  24. Pencils Cards Rope String Hatpin Balloons Rubber bands Scotch tape Paperclips Fake dollar bill Penny Bent penny 3 Card Monte Professor’s Nightmare Floating gimmick Styrofoam cup Goodie Bag & Handbook CSESI 2009

  25. Wrist Twister • Page 12 • Penetration – break your wrist • Switching – change the position • Concealment – hide the position • Misdirection CSESI 2009

  26. Pick Any Card • Page 24 • Mental – predict the future • Forcing – you know which card • Revelation – how to reveal prediction? • Misdirection CSESI 2009

  27. Sticky Pencil & Stickier Pencil • Pages 29 & 30 • Levitation – defy gravity • Concealment – hide the mechanics • Misdirection CSESI 2009

  28. Napkinesis • Page 42 • Vanish • Concealment • Misdirection CSESI 2009

  29. Professor’s Nightmare • Page 34 • Transposition • Switching • Concealment • Misdirection CSESI 2009

  30. Other Tricks • Three Card Monte (36) – big cards • Instant Reconnect (37) – piece of string • Dematerializing Toothpick (43)– tape, toothpick • Cut & Restored Rope (13) – rope & scissors • Magician’s Choice (23) – any 3 objects • Mind Bending Coin (35) & utility switch CSESI 2009

  31. More Tricks • Coin Vanish (40) – coin or other object • Karate Dollar (14) – dollar & pencil • Balloon Testing (16) – balloons & pin • Linking Paper Clips (17) – dollar & 2 paperclips • Jumping Rubber Band (18) – 1 rubber band CSESI 2009

  32. Still More Tricks • Reversal of Expectation (38) – cards • Pincushion Thumb (19) – napkin & pin • Haunted Styrofoam Cup (28) – cup • Cup Juggling (31) – cup • Vanishing Card (41) – napkin, stirrer, cards CSESI 2009

  33. Resources • Public library • Internet • Google: easy magic tricks • Google: online magic trick • Magic shops • Yellow pages • Online shops (e.g., magicfact.com) • Web sites for magician’s • allmagic.com CSESI 2009

  34. Grand finale!

  35. Straitjacket • Invented by Dr. Benjamin Rush, 1814 • Believed that torture was good medicine • Restrains the “criminally insane” • Designed to be escape proof • Trying to escape leads to exhaustion • Still used today CSESI 2009
