  • The Mathologer puts the latest $2000 addition to his Klein bottle collection to work. A couple of first-ever fun mathematical stunts in this video. This video finishes with a puzzle for you to think about. We posted a video with the solution on 1 August 2015: thexvid.com/video/ZMC61C5tigA/video.html
    Enjoy!
    Burkard Polster and Giuseppe Geracitano
    P.S.: Most of of Burkard's glass Klein bottles as well as the Klein bottle hat were made by Cliff Stoll of ACME Klein bottles (www.kleinbottle.com). The metal 3d-printed Klein bottle opener was made by Bathsheba Grossman (www.bathsheba.com).

    Surely a glass klein bottle has more than one edge because you can't get inside it physically?

    I don't get the whole 4th dimension. Seems like he just edited it and just went yup they still connect cause of reasons.
    And the mirror image on mobius, he lost be there. Sure to be a mirror image your past self would still need to be there when you arrive at that point once you been rotated. Just seems all abit bizarre to an uneducated fool like me

    If they put a piece across, covering the tube where it meets the bulbous part, wouldn't that cancel the "there is no inside or outside" aspect of the klein bottle?

    At 6:30 if the figure went around the whole strip, wouldn't it be facing the same way???

      So how does the figure on the left bottom end up facing the wrong way ( to me its the wrong way ). Shouldn't the feet be on the bottom facing right??

    I wonder how many of the over 1.7mil was tricked onto this useless video like I was. Think the more than half of the 14K who did the thumby thingy gives the answer. 7.5K thumbs down, plus mine. Honesty truly eludes the multitude, especially the TheXvid video posters/posers. Gguess it doesn't matter as long as you're getting paid, or getting a rise out of it, or both. Total waste of sixteen minutes and a whole other twelve seconds atop the comment time. Never again!!!

      I think I understand what you're getting at here. Imagine a 2D world, you as a 3D person would be able to observe it from both sides of the plane right. But for the 2D person, it would seem like that other 2D person would have ended up at the same place even though from our perspective he has only traveled 1/2 the distance. This is (I think) assuming that it would be possible for the 2D person to actually be able to rotate along its axis to begin with. My question is, what is the equivalent action of rotating around your axis in a 2D world in a 3D world and would you survive it?

    I think if there is a very smail "ring" of glass missing "outside" the smaller tube, then it would be a Klein bottle. NO matter where you go, it's the same surface. Even if you would go through the "ring " from the 3 dimensional outer surface, it's still the same.

  • Vinyasi

    You've probably heard this from someone else. What you're describing is called karma which, of course, is a rewording of Newton's Action and Reaction business.
    But here's my contribution...
    Charlie Lutes was a friend to many practitioners of Transcendental Meditation. He used to frequently say how consciousness is equivalent to karma for all intents and purposes. And we know that consciousness can recreate our physical existence by adepts of Yoga who are accomplished yogis: perfected humans, aka saints. In the Sanskrit, they're called: siddhas.
    So, a mirrored image of one's self returning to one's self traveling along on a mobius-strip-model of the universe is indeed the karmic consequential consciousness of one's own self.
    Thus, whenever we hear about that ancient Greek superlative which spells out: "Be true to one's self" (To thine own self be true) is really good advice since our karma will demand this of our selves (whether or not we want it to) due to what you are presenting is following the laws of the universe requiring our consciousness, literally our very existence, must report back to one's self the full effects of one's actions! And not merely some of our actions (the one's we like to remind ourselves about), but all of them: both the good, the bad and everything else in between...
    And this also exhibits how our actions return as a mirrored image of their original copy to give us a viewpoint outside our self what our actions looked like from the perspective of the universe of the other creatures who will receive these actions of ours. All too often we think that we do good things. And we have the best of intentions. But that doesn't mean that our good intentions guarantees good effects. For what if the receiver of our actions sees the opposite due to their own unique interpretation flips the appearance (and judgment) of our action into a hideous nightmare for themselves to receive from our good intentioned actions? What then?
    How do we explain to them we meant no harm if they can't help but see only harm come to them from ourselves if that's the only way which they can see it? And the only way they must experience it? What then?
    Mother Nature knows all too well of this possibility occurring. So, She engineers it so that all actions of any sort are reflected back to our self as a mirrored reflection of its original copy. Voila! Now, we have a true perspective based on a wholesome view of action as seen from both sides of an action: both the sender's viewpoint and the receiver's viewpoint constructing a unified view of action and reaction. Which is Mother Nature's viewpoint. So, why shouldn't it be ours, also?
    Are we not made in the image (likeness) of God? So, why shouldn't we be Gods to one another?...
    Or, as it is proclaimed by several of the characters (one of them portrayed by a very young Keanu Reeves along with George Carlin portraying another character) in the movie, Bill and Ted's Excellent Adventure: "Be excellent to each other!" And...
    "Party on, dudes!"

    4th dimension is time. how do you move it in time?
    And that is not mirrored.
    Using the mirror feature on paint doens't make it mirrored for real.
    Besides, if gravity still functions in the strip, then the man won't be turned, just, perhaps, squished.

    The fact that he doesn’t show how he does it, is the joke. Remember how he talks about a “true” Klein bottle would be in the 4th dimension, but part is invisible to us.
    That’s what he did at the end. The editing of the video at the end is the “invisible 4th dimension” in how he gets the cube inside.
    Kind of a clever joke.
