Holy wank, i also came here for that reason and was about to comment that, this is like the 4-5 time it gets recommended to me, this video always gets recommended to me from 4 to 4 months.
Who the fuck got up in the morning and thought "Man, how could I turn a sphere consisting of material that can pass through itself but dissolves when being bend in a sharp bend, inside out?"?
The year was 2009. I was chatting on Messenger (Windows', not Facebook's) with my crush for the first time since I finally got an internet connection in my home. I could text her without spending on SMS! Cool. So we were just chatting about anime or something along the lines, and before she went offline to sleep she sends me this out of nowhere. This was the first "viral video" I was sent. "This is pretty cool, good night" she says. We never got together because she wasn't interested. A couple of weeks ago I saw her at the entrace of a local concert and we played dumb like we didn't know each other after our eyes met. Didn't see her for the rest of the night. Every now and then when RU-vid recommends me this I watch it for a couple of minutes to remember how weird those times were. I wonder if she does the same. I doubt it, honestly. Thank you.
Female narrator: Well, look here. A toilet. Alright, let me show you how it's done first. Male narrator: Ok. Female: *goes to the bathroom* alright, now you try. Male: Shits all over the ground. Female: No no, you need to do it like this! *sits on the toilet* Male: Ok, I think I got the hang of it.
This is the middle of RU-vid, people who watch videos of all kinds from Minecraft let's plays, to sports, to dank memes, and everything in between can all be found here. The borders of RU-vid have been knocked down. Now everyone, explore the vast RU-vid cultures in the comment sections.
As a kid and young teenager I use to run a channel on amateur rocketry till'em moors started setting off bombs everywhere and had to take down most of my vids on how to make rocket fuel and so on, things were getting messy during the Arab spring and I started getting messages asking for tutorials on making bombs... etc :(
It'll really help on your math test: instead of thinking of those weird equations, memorize the script HEY, I READ SOMEWHERE THAT MATH METITAINS CAN TURN A SPHERE INSIDE OUT
wonderguardstalker isn't that what's happening? these two voices are teaching me how to ruin basketball. and i must do their bidding. jk im not insane.
"And who fucking cares if we're related? Do you think the scientists who learned how to turn a sphere inside out followed the rules? Fuck no. They threw everything they knew out the window and started experimenting, even if it was with their family members"
Does anybody know an actual reason why this information would ever be useful? Clearly we're never able to push two physical objects into one another without defying laws of matter and gravity so this is only going to be possible in a computer simulation. The fact that this actually exists with such professional backgrounding without any actual reason for it to exist is actually bugging me for whatever reason.
The video is talking about topology, or differential topology to be more exact. And while its applications are not "useful" in our everyday lives, it is cosntantly applied in biology, physics, and computer science. This year's Nobel Prize in Physics was awarded to topology in condensed matter. This is the application of the mathematical objects in the video (holes, twists, turning number, defects and all) to real life materials. These materials are important when we talk about making superconductors, transistors etc. Not all subjects in pure math are "useful" as you have defined it. But when complex numbers and imaginary numbers were first discovered, no one thought it would be important; because they weren't "useful" in the real world. Nowadays, complex numbers are used in computer algorithms, electronics, quantum mechanics etc.
Jason Jahn The video should be title "How to solve a useless math equation". They asked the question "How do we turn a sphere inside out?" Then they realized no amount of math makes that possible in real life. So they made an imaginary material so it is possible, but then it became too easy. So they decided to add a limitation that doesn't fit said material to make it more difficult. Don't you see how stupid this is?
i feel ive watched this video about 20 times over the period of 10 years and every time i watch it i understand a little more. this is the center of the internet
Hey! Want to turn a sphere inside out? No worries, we made some special rules so that you can do it Oh, and you have a sports band? Have you tried turning it inside out **you turn your band inside out** Oh, but that does not play with our rules >:( See, you can't turn a band inside out, but you can do it to a sphere YES!
+InteristaSbarazzinoXxX98 This video is approximately ten minutes and thirty seconds, at a frame rate of 30fps, giving a total length in frames at approximately 18,900 frames. Each frame is 320x240 in dimensions, which means each frame consists of 76,800 pixels. Therefore the total number of pixels in this video is approximately 1,451,520,000. If you had a cent for every pixel in this video, you'd have over fourteen and a half million dollars. I wish I had a cent for every pixel in this video.
This is a visual simplification of one of many results from the wonderful field of topology. If you want to know why mathematics matter, just think about the device you're reading this on and think whether you really believe it'd exist without advanced mathematics.
Grant Hashimoto Complex numbers also don't »exist« in real life and yet modern technology wouldn't exist without them. Sometimes things don't apply directly to the real world, that doesn't make them irrelevant. They might still serve an important purpose.
I love this style of educational video. If you want to explain something properly, you need a character that mimics the viewer and asks the same questions. You can't just have an expert shove it in your face with no resistance.
***** Right, but this isn't science. It's topology. And the rules of topology are that you can stretch, bend, or fold a manifold as long as you don't rip, tear, or glue things together.
This has been on my reccomendations for years, I've already seen it, yet still get recommended it. It's like the black hole of RU-vid, no matter what you watch, if you keep on clicking you always end up here
try it with spacetime. we know spacetime bends. could you create a pocket dimension with this method? I's be interested in that kind of research... I can't think of anything else that might be able to pass through itself. this kind of math is helpful for M-theory though, right?
I watched this when I was 9 years old, and I'm now graduating with a Mathematics degree one year from now. Shoutout to this video for getting me into topology and pure math in general.
I keep seeing this "arbitrary rules" comment. These rules aren't arbitrary, this video discusses the field of Topology which relates to the infinite deformation of a surface while not tearing, pinching, or gluing the surface. These rules relate back to calculus, where if a curve was not smooth, or not continuous at all, then it was not differentiate-able at that point. Instead of a curve, these are now surfaces, and the pinching/tearing relates to the curvature of the surface being continuous and differentiate-able. This is where the rules come from. Look up Topology sometime, it is very interesting.
Wow I'm the only one who watched this through to the end. Isn't anybody else concerned that the video cuts off before it actually shows you how to turn a sphere inside out? I mean the explained version they say is coming at the end and then it just cuts off
It is being turned infinitely tight. This is because it can pass through itself, but it cannot be fully creased on itself. This means the rim is turning infinitely tight because it cannot be creased. Yes, infinitely.
