    wow this was very interesting until the point i realized that you will not explain how you got the cube in there. Now i am dissapointed af...:(

    Thank you, Mathologer.
    I do not have the math background to "figure it out," but I nonetheless keep surfing TheXvid in search of intellectual crutches that might - one bright day - convey to me an inkling of what you and the other uber-maths are able to apprehend.
    How curious that our senses can only perceive three spacial dimensions (and yet, know we are - femtosecond by femtosecond- propelled along an imperceptible, yet existentially experienced fourth dimension), only to have our minds inexorably compelled by the evidence to seriously consider as real psychedelic possibilities far beyond our individual and collective waking experience .
    Reality should blow our minds, right?
    The apprehension of mystery is the fundamental posture of the human intellect.
    Thanks again.

    Please don’t introduce this man to a gyroscope because if this gets him all giddy imagine what a gyroscope would do to him.
    Think I am kidding? Just search gyroscope in TheXvid search Engine. There are people that spend their whole life thinking there is some magical power that could be harvested with the the right know how. 🤪

    Seriously what was that. The way he laughs as he reveals more and more “Klein bottles” is so unnatural it feels like a parody. Just when you think it’s actually un-ironic, “Klein bottle hat!,” “Klein bottle inside a Klein bottle.” But then out of nowhere a seemingly serious video brings rubix cubes into it for no reason other than its in the title? And they don’t even show it??? Am I missing something???

    6:50 you are missing out half of the journey around the strip, he is still facing the same way going in the same direction. He hasn't traveled all the way around the strips one side, when he should disappear onto the unseen part of the strip on your diagram you have him appearing on the wrong part of the strip instead?! naff

    This is becoming a most gooberish experience. I’m a bit fascinated with his fascination of his own fascination with some silly conceptual math humor...but now nodding off. How many times can you say “Klein bottle” in one sentence? Answer: too many! Seriously, any bottle has only one side, by strict definition... prove me wrong.

    This was a very interesting video. That said, I don't understand the hateful comments. Do you people want him to do a card trick? Or to pull something out of a hat? Don't listen to the people who came to "see how he got the cube in the bottle". The mathematical and geometric concepts you presented in the video are clearly too much for their feeble brains to understand. They can go elsewhere to have their elementary minds stimulated. Again, great video. You've just earned an interested subscriber.

    Why is it called "Klein Bottle". Klein was originaly talking about "Fläche" that means surface. But when they translated it, they used the word "Flasche", looks similar but means bottle. So it has originally nothing to do with a bottle. It was meant as a 4 dimensional surface. But now everybody, remembers it as bottle. (Sorry when I made some mistakes, my native language is german and not english.)

  • Nico Steiner

    I like the presentation style of your videos. It is well thought, properly adjusted and perfectly "crafted" for each single topic. Presenting a Möbius strip or the calculation of infinite numbers is quite a challenge, not to speak about these "self including" inside-out Klein bottle creatures. But you are doing so very well for all these challenges, Sir. Each of your videos is a testament to your deep-rooted passion for mathematics.

  • P Schmied
    P Schmied Month ago

    The so-called glass klein bottle is NOT a paradox. It is topographically identical to an open cup, which ALSO has one surface, enclosing the material of the glass
    Making holes through a solid object does not change that fact that it is solid. A finite flat sheet of glass also has one surface because the "edges" are simply a portion of a continuous surface which is acutely deformed through space.

  • Carlos Robinson

    Your mirror image illustration of the Mobius strip is incorrect.

    • Carlos Robinson
      Carlos Robinson Month ago

      The Paradox exists because... Well, you can exist in more than one dimension at a time, but you always exist in one more Dimension than you can accurately perceive. For example, we know that we exist in at least the three dimensions that we have some measure of Mastery over. But we also exists and can probably be perceived from other dimensions as well that we ourselves cannot perceive because it is beyond our dimensional capabilities. Do we have an accurate understanding of what the 4th Dimension is? No, because although we exist in it and can perceive its effect upon us, we cannot accurately Define it. It is beyond our sensory capabilities, and therefore beyond our ability to deductively define it.

    • Carlos Robinson
      Carlos Robinson Month ago

      Let me explain. You are thinking of a Mobius strip as a two-dimensional object when it requires at least three dimensions for it to be created.
      You erroneously continued the upside down figure of the two dimensional person on the wrong plane; it would take two revolutions of the Mobius strip for the person to end up at their starting point. The real Paradox is that you never occupy the same space even though you are traveling along a single plane without turning to return to your original starting place. But your orientation would still be the same. The mirror Paradox is that when you are at the same "point" of the Mobius strip after one single revolution, you wouldn't be in the same "place", and it would be at that point that you are a mirror of yourself, albeit not existing in exactly the same space.

    what's the point of a Klein bottle? it provides no mathematical proof or solve any theory, its simple creating a solution to a problem you've created... this renders it useless....

  • Bogdan N
    Bogdan N Month ago

    That example with the 2 dimension man walking on the Moebius strip is WRONG! If you start from a point on the strip and follow along it, you will reach that point periodically, and facing in the same direction. In the example provided, you cross the boundary of the strip, on left side of the picture. I believe you found a way to defy the laws of thermodynamics, too?
