    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:)

    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.

    That also explains why cutting it in half twice gets you two linked rings. It is like cutting it in thirds, then cutting the middle one in half again.

      I think when n is odd in 1/n it will create a circle in the loop. Otherwise, it will just create a single loop.

    Sir Frances Bacon said "Wonder is the seed of knowledge". How true he was! Now I want to learn more about topology. Over the years, I've acquired more useful and thought-provoking information from RUclips videos than I ever managed to absorb from the countless hours wasted in the classroom - and that's because "RUclips Professors" like you exist. You guys and gals know how to take (notoriously boring) subjects and make them interesting and fun - and of course voluntary learning is so much more fulfilling than forced learning. I'm not trying to bash public schools .... like most things in life, some are good, some are bad, and some are "meh". Some of the teachers I had were amazing people who genuinely enjoyed sharing their knowledge with young minds. Some teachers did the bare minimum required of them as they counted down the days until retirement. Other teachers missed their true calling .... as prison guards. It takes a different approach to engage independent learners and those who may have focus/attention issues. It takes more than just textbooks and scribbles on a chalkboard to make such students want to learn. Maybe things have changed since my high school days, (Class of 1992) but a hands-on approach accompanied by visual aids (much like this one) would have made learning a lot less stressful and frustrating. Only a handful of teachers understood that, so learning was a struggle for me and students like me. Thank goodness for people like you who make people like me want to learn and use our imaginations! Thank you for taking the time to make this video.

    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 +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 7 лет назад +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 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.
