  1. DeYoung Museum, June12, 2013 MATHEMATICAL TREASURE HUNTS Tracking Twisted Toroids Carlo H. Séquin University of California, Berkeley

  2. What came first: Art or Mathematics ? • Question posed Nov. 16, 2006 by Dr. Ivan Sutherland“father” of computer graphics (SKETCHPAD, 1963).

  3. Early “Free-Form” Art Cave paintings, Lascaux Venus von Willendorf

  4. Regular, Geometric Art • Early art: Patterns on bones, pots, weavings... • Mathematics (geometry) to help make things fit:

  5. Geometry ! • Descriptive Geometry – love since high school

  24. Schematic Model of 2-Link Torus • Knife blades rotate through 360 degreesas it sweep once around the torus ring. 360°

  25. Slicing a Bagel . . .

  26. From George Hart’s web page:http://www.georgehart.com/bagel/bagel.html . . . and Adding Cream Cheese

  27. Schematic Model of 2-Link Torus • 2 knife blades rotate through 360 degreesas they sweep once around the torus ring. 360°

  28. Generalize this to 3-Link Torus • Use a 3-blade“knife” 360°

  29. Generalization to 4-Link Torus • Use a 4-blade knife, square cross section

  30. Generalization to 6-Link Torus 6 triangles forming a hexagonal cross section

  31. Keizo Ushio’s Multi-Loop Cuts • There is a second parameter: • If we change twist angle of the cutting knife, torus may not get split into separate rings! 180° 360°540°

  32. Cutting with a Multi-Blade Knife • Use a knife with b blades, • Twist knife through t * 360° / b. b = 2, t = 1; b = 3, t = 1; b = 3, t = 2.

  33. Cutting with a Multi-Blade Knife ... • results in a(t, b)-torus link; • each component is a (t/g, b/g)-torus knot, • where g = GCD (t, b). b = 4, t = 2  two double loops.

  34. ART: Focus on thecutting space !Use “thick knife”. “Moebius Space” (Séquin, 2000)

  35. Anish Kapoor’s “Bean” in Chicago

  36. Keizo Ushio, 2004

  37. It is a Möbius Band ! • A closed ribbon with a 180° flip; • A single-sided surface with a single edge:

  38. Changing Shapes of a Möbius Band • Using a “magic” surface material that can pass through itself. +180°(ccw), 0°, –180°, –540°(cw) Apparent twist (compared to a rotation-minimizing frame) Regular Homotopies

  43. Splitting Other Stuff What if we started with something more intricate than a torus ?. . . and then split that shape . . .

  44. Splitting Möbius Bands (not just tori) Keizo Ushio 1990

  45. Splitting Möbius Bands M.C.Escher FDM-model, thin FDM-model, thick

  46. Splitting a Band with a Twist of 540°by Keizo Ushio (1994) Bondi, 2001

  47. Another Way to Split the Möbius Band Metal band available from Valett Design: conrad@valett.de

  48. SOME HANDS-ON ACTIVITIES • Splitting Möbius Strips • Double-layer Möbius Strips • Escher’s Split Möbius Band

  49. Activity #1: Möbius Strips For people who have not previously played with physical Möbius strips. • Take an 11” long white paper strip; bend it into a loop; • But before joining the end, flip one end an odd number of times: +/– 180°or 540°; • Compare results among students:How many different bands do you find? • Take a marker pen and draw a line ¼” offfrom one of the edges . . .Continue the line until it closes (What happens?) • Cut the strip lengthwise down the middle . . .(What happens? -- Discuss with neighbors!)

  50. Activity #2: Double Möbius Strips • Take TWO 11” long, 2-color paper strips;put them on top of each other so touching colors match;bend sandwich into a loop; join after 1 or 3 flips( tape the two layers individually! ). • Convince yourself that strips are separate by passing a pencil or small paper piece around the whole loop. • Separate (open-up) the two loops. • Put the configuration back together.
