Euler's Disc (Euler is pronounced 'Oiler') is a fascinating physics toy that mesmerises everyone that sees it.
The base is a slightly concave mirror. There is then a heavy metal disc, which you place on the mirror, and spin. What happens then? Well, just like spinning a coin on a table, the disc both spins and rolls, until it comes to a sudden stop, the final stages being accompanied by a sound of increasing frequency.
A coin spun on a table will not spin for all that long. Euler's Disc, by contrast, spins for a long time before coming to rest. In addition, there are a number of magnetic holographic decals that you can attach to the upper side of the disc to enhance the effect of the spinning action. The best thing really is to watch the video. It is a lot of fun showing this to someone who has not seen it before. The ending is really spectacular. It also has a spectacular name - a finite-time singularity!
Euler's Disc was invented by Joseph Bendik in the 1980s, while he was working for an aerospace firm in California, and spinning coins on the cafeteria table. He named it after Leonhard Euler, a Swiss mathematician and physicist who lived from 1707 to 1783, and who did some of the pioneering work on spinning and rolling objects.

The sound reminds me of the one scene where a character slowly goes crazy but snaps back into reality at the last second
you're right, it does sound like that.
My thoughts exactly
The little “wow” at the end really makes it
Tim is really the cherry on top of his toy videos. Heck, he’s the whole sundae. Seeing the cool toys is the cherry.
I said the same thing! Lol.
I said wow just before I read this comment, and his wow came immediately after 🤣

Could one somehow harness the kinetic energy and store it in a battery?
@@RobertWilkinsonJKekMaloy Hey, you might be on to something there. I'm thinking something similar to those power-generating sidewalks in Japan.
@@RobertWilkinsonJKekMaloy Sadly no, it only has as much energy as was put in when it fell, which is not a lot.

My mother used to run a book store in Los Alamos that was also partially an educational toy store. Had lots of science type toys, the kinds of things scientists would buy for their kids because a lot of scientists came in to buy books they couldn't otherwise find (this was before Amazon). We ALWAYS had Eulers Discs in the store, they were one of the biggest sellers and I played with them all day long. Good times.
So you started it in the morning and it stopped right when it was time to go home? 🤭
Legend has it that it’s still spinning and that’s why UA-cam algorithm shows it

When the noise is increasing, at one point it begins to remind me of the humming noise you experience while on a psychedelic experience.

lmao you won this videos comment section congrats here is your tofu
Giganotti it’s purely psychological. When you drop something at night it may seem the sound is louder but in reality everything is quiet around especially with everyone sleeping which gives that illusion that whatever you drop sounds louder.

There's a mathematician who researched everything that is going on here. And that is more than you'd think. For different weight and size discs, now he can predict how long it will wiggle. Ancient problem solved!
Well, not being a mathematician and not even good at doing sums, I made my one through trial and error combinations of various unknown bits and bobs like brass shower tap washers etc and d/sided tape or duct tape . Its incredibly impressive if I do say, and I do. What's this Ancient problem ?
@@robertmcgivern565 predicting how long it will wiggle. Making one doesn't mean you know how it works
@@seanseen_ kinetic energy like a flywheel it needs weight, and despite what others say doesn't need a machine rolled edge. You appear to be in awe of academic achievements, it's mostly BS. Academia is not some place for clever and learned people, it's mostly housing fraudsters and outright dickheads being paid to front a centuries old class system racket .
@@robertmcgivern565 you asked what the "ancient problem" was and I told you what it was. All I was saying is that someone did a mathematical analysis of the object, which I think is kinda cool. I'm not defending or even talking about the academic system. I'm talking about one guy who did some maths, how does that relate to the academic system?
@@seanseen_ called baffling them with science. Mathematicians talk a different language and unless you already understand, would take years of study just in order to challenge them. There's always been a constant overellaboration to the simplest things. Consider why the law was (until recently) written and practiced solely in Latin , yet majority children schooled in basic English. This mathematician, how does he calculate the impetus or amount of spin an individual puts in ?
What's really mind bending is the thought that it's still going after you stop being able to hear it. Motion so fast and small that you cannot hear the frequency or see it moving. In fact, does it ever truly stop? Far out, man.
