  • @vpambs1pt

    Everything is on point, that's interesing! what if we cut in 4 pieces? would we have 2 Möbius strips, but each one "inside" the other?

    • @ThinkTwiceLtu
      @ThinkTwiceLtu  7 лет назад +397

      if we cut in 4 pieces, I think we would get 2 linked loops but i don't think that they would be mobius loops anymore because they would have an even number of turns on them therefore they would have 2 separate faces. correct me if i'm wrong

    • @vpambs1pt
      @vpambs1pt 7 лет назад +222

      I'm not a topologist and not even close to be a mathematician(still in high school), but I did it myselft with paper and adhesive tape haahaha, and at the end you are completely right, I just didn't understand how did you know that they'd have an even number of turns.
      It's nice to know that you're recovering and not at the hospital anymore, get better!!!

    • @jursamaj
      @jursamaj 6 лет назад +57

      For 4, the middle 1/2 is identical to a Möbius cut down the middle: double long, double twisted loop. The outer half is 1 piece due to the outer edge, but now has an inner edge, so it's the same: double long, double twisted loop. So the result is 2 pieces just like a Möbius cut down the middle, but half as wide.
      In fact, cutting any distance from the edge will yield a double long, double twisted loop. So for 1/N being the distance between cuts, you'll get int(N/2) double long, double twisted loops. If N is odd, you will also get a narrow Möbius down the centerline.

    I would love to see a part 2 with an animation of two Möbius strips with ’opposite’ twists getting their edges glued together to form a Klein bottle, as well as an animation of a mobius stip getting its edge glued to the edge of a unit disk to form a real projective plane, if possible. This was a wonderful video with smooth animations and tips/explanations. Thank you.

    A great way to explain it by cutting the strips and then twisting them, thanks. I have one for you. If the formula for the surface area of a circle is πr2, should the volume of a sphere be πr3? I would love to see a visual explanation of that.
