    About the video:
    Exploring the properties and other unexpected shapes that we get by cutting up some Mobius strips.
    This video is a lot more text heavy compared to most of my previous ones, however it's quite difficult to explain something in more depth without using a lot of words.
    Thanks for watching:)

    When I was little, I knew something happened when you cut a Möbius strip in half, but I didn’t know what, so as a child my brain defaulted to physics breaking.

      I would encourage you to rewatch the video, perhaps pausing at the questions and try to figure it out yourself. It really is quite intuitive, and very satisfying once you get it. You can do it!

    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  Před 6 lety +393

      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 Před 6 lety +219

      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 Před 5 lety +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.
