    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 have been fascinated by the " basic" mobius strip for a long time and I never imagined the result of cutting one in half or more counterintuitively at the 1/3 point. My mind, brain and imagination are in ecstatic mode! Thank You!

    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 +58

      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.

    Thumbnail, title, and concept made me think of that “Outside in” video, the one so many including myself got recommended where there’s a Female and Male voice explaining a concept like this, and the comment’s on it of course are a laugh 😂, thank you for making this!

    Update 2: I don’t deserve a thousand likes, I just said that because I didn’t see anyone else say how it reminded them of the inside out loop educational video, I still wish you all the very best and that God Blesses you all greatly in life, take care, and please spread love as much as you can and then some 😇☺️🌄

This was a wonderful video with smooth animations and tips/explanations. Thank you.
