I think Mr Tokieda just walks up to something, wiggles it a bit, taps it with a spoon, or something similar. Then discovers some subtle universal truth. Zen master for sure!
Debashis Mondal same here, it made me realize that math is an exciting field with all kinds of discoveries to be made and beautiful geometries to be constructed and now I've applied to colleges for mathematics
I was already kinda interested, but Numberphile really put the last nail in the coffin labeled "vocational school" for me. Now I am in gymnasium and I'm happier than I could have ever been fixing cars or shit.
Oh, I had a toy like this when I was a kid! It was a wooden kite that climbed vertically on two strings you pulled in an alternating fashion. I've been always fascinated by it. Thanks for finally explaining it, Mr Tokieda!
This guy just keeps coming up with the most fascinating phenomenons about everyday objects, and its most intriguing! Big thanks to Tadashi, and keep doing what you do!
A comment in limerick format? I believe it's the first time I saw that. While the comment's abnormal, I'm a sucker for formal Experimentation, and nobody's doormat. So you get a like.
Tadashi playing with string on his feet Nothing else can make me feel more complete Yea, I am a simple dude Just showing my gratitude Since I've been watching this clip on repeat Title: My Love for Tadashi
This guy is one of the best guests. I'm not knocking other guests, because I love them, too, but there's just something about Tadashi Tokieda that is.. I don't know, comforting. I feel like watching his videos is some enlightening meditation. I come away feeling happy and relaxed.
The cartoon parts are threaded wrongly which made this a bit confusing. The cartoon has the threads going through the binder clips asymmetrically, whereas when shown in real footage they are going through symmetrically.
Tadashi needs his own broadcast into our minds 24/7. First and foremost, to make us smile and laugh and, you know, all the invaluable knowledge that comes with him. Thank you sir.
To me, this was a perfect display of water currents. how water goes down a stream and fish ride the up flow up. Like Victor Schauberger described. Awesome!
lol, I think in every video I have seen he gets his feet out and uses them. I don't understand all the jargon exactly, but my layman understanding of this is basically that when the metal ring area turns in the thread it is able to latch onto the thread because of this more intense angle, where as the angle on the other ring side is less intense and thus slides more than grabs.
calvinhobbesliker2 look at the video thumbnail. notice how it is threaded. for both sides the string comes into the clip on the bottom side. that makes it go up.
@@CSDragon the actual photage and the thumbnail differ from the animation in the video. I understand the general principle of friction, but the details are still somewhat fuzzy.
There is one detail that I don't think he really mentions, it's that if you want the clip to move away from you, the "ropes" must pass throught the metal holes from the outside part of the clip towards the inside, whereas if you want it to come towards you, you should pass the ropes from the inside of the clip towards the outside part. If you pay close attention you can notice that that is what really changes when he takes the rope and puts it down on the opposite side. I hope I am making sense :P
I love thees videos. my maths teacher in school told me that asians schools had extreamly good methods for teaching maths but didn't have much practical use of it while european schools have practical use of math in our school but the level of math is realy low. I always loved implementing logic in reality so Tadashi is my favourite person on numberphile :)
Scaled up to a very large size, this method could be used to launch satellites into orbit. Simply suspend two very long cables from a satellite in orbit down to the earth, and then use the cables as a space elevator via the method demonstrated in the video.
The Thread in the animation is wrong on one side. The left side has to be a mirror of the right side, so that both sides of the bottom thread enter the clip's holes from the outside.
The animation at 2:31 is wrong (in that configuration, the clip just follows gravity), but the animation at 3:03 is right. The string must be threaded as a mirror image, and it will go toward the direction that has the threads on the inside. I built my own version of this to confirm. Also look at the physical version at 3:13, you can see how it is threaded.
Little known fact ... binder clips were originally designed to transport paper on strings from one office floor to another through this back and forth motion.
What are the odds that I woke up today with the word Funicular stuck in my brain and was uttering it under my breath all day and this video comes out about them?
I didn't know there was a debate about which channel to put this on but the answer is simple, subscribe to both Numberphile and Sixty Symbols. Problem solved, and that one was on the house.
Very cool video, just a small nitpick: I'm pretty sure static and dynamic friction play no role here. Friction is proportional to the contact force, which is larger when the string wraps around the clip, no need for fancy phenomena.
I know this same principe with little toy figures, that have two drill holes in their hands slightly tilted towards each other at the top. And they worpk even if the string is not a loose loop. It can be two strings knotted tight to the ends of a little horizontal bar at the top point. And it works if the strings are almost vertical. I´m pretty sure i saw this somehow that it looked like theese classic autumn decoration kites, cut out of a wooden plate and with theese holes for the string close to the side corners.
My hoodie string got stuck in my hoodie today. I thought it was lost for, but then I thought of this video, and sure enough, by pinching the hard bit forwards and backwards repeatedly, the hoodie string slowly inched out of the hoodie.
