Oh God it's one of those videos where every comment is a top comment :O I need to make mine super cool so I am not the only one with no thumbs up. Aw screw it
I figured it out. The Universe: Windows and Apple had a baby using Ubuntu as a womb. Some things may not make any sense and seem downright ridiculous, but the math works out. lol
i like how the sound starts building up right at the beginning of the video, and near the end it keeps going up until it abruptly stops. how oddly satisfying.
The concave surface acts, at first, to keep the disk spinning in one small area, rather than travelling across the table as a coin would. Beyond that, it is curved at such an angle as to reduce the contact that the disk has with its surface, reducing friction so the disk can continue spinning as long as possible.
@MaskedGuardian0 It is a low-friction surface, and a very heavy disk with a beveled edge. There are no magnets, though a lot of people guess that there are. The slightly concave mirror helps with the conversion of potential energy to rotational energy.
Exactly. Both the disk and the mirror are highly polished, very smooth surfaces. The disk also has a slight bevel so that as little of it as possible is in contact with the mirror as it spins.
The funny thing is the disk itself is actually slowing down over time, until it's hardly moving at all near the end, which can be verified by putting a dot on the disk and watching the dot move (or using a coin, which has clearly identifiable features). It's the point of contact with the base that moves faster and faster, and that's what's causing the sound.
DO you know the technical name for the sound that this makes? I used to, but I cannot remember it. Something like 'Coriolis Sound' but of course, not that.
I don't know why but every piece of electronic music I listen to now I can hear Euler's disk spinning in the background. it started up around 10 minutes after playing with it
I just got one of these. The sound and duration are real. There's no batteries or magnets. The disc itself is pretty heavy. It's pure physics; potential energy (lifting the disc to an angle) and kinetic energy (spinning it) and even a gentle spin will get 2+ min of rotation.
At some time, it looks like the point of contact rotates although the disk does not. As the energy in the disk is lost, the rotation paradoxically increases. When it seems to be accellerating without bounds, it suddenly buzzes and stops. I am not sure if it is necessary to spin the disk to get this going. You've seen this when dropping a coin. I once saw this with a manhole cover when the person tried to set it on the pavement without trapping his fingers. It didn't last very long.
it's an action called either sprolling or spolling, i can't remember which, which is (you guessed it) a compination of spinning and rolling. the reason it last so long is that any energy lost to the spinning goes into the rolling, and vice versa. the mirror it rolls on is also slightly concave, which helps.
Rotation of the actual disk doesn't speed up, but if you were to monitor the single point of contact of the disc to the table towards the end that single point would be moving around very quickly.
I was under the impression that the geometric shape is spelled "disk" (to refer to either an extremely shallow cylinder like a coin or even a zero-height cylinder) whereas the "disc" spelling indicates optical storage media with that shape. A quick search indicates that a lot of people say there's a difference, and a lot of people say they're largely interchangeable. Since "disk" predates "disc", the latter spelling sounds anachronistic when used outside IT.
Of course you will break your finger, are you serious? The disc is spinning at v=100 m/s and the mass is about 1kg. This combined with its lorentz factor of 5.6 (due to 1/(1-v^2/c^2)^1/2) gives it a momentum of just about 3 meganewtonseconds which is by far enough to break a finger, maybe even your neck...........
This effect is not caused by the speed of rotation on the disc, but the speed of the wobble, The actual rpms is probably very disappointing. The concave mirror causes the the disk to wobble exponentially faster as it tumbles on the curves of the mirror, Really to reproduce this, you need a disc that has some weight and a curved mirror.
If there was a magnet, it would have to be a moving one in order to keep the disk spinning. That would require electricity. A stationary magnet would hamper the disk's movement, not aide it. It would probably just make the disk stick to the base. Rather, this is a demonstration of inertia, rotational momentum, and low friction.
In this case, the important element isn't that it's a mirror; it's that it's slightly concave. That helps the disk spin for a longer time. Spinning it on a completely flat surface would just mean it wouldn't spin for as long. It would be like spinning a large, heavy coin.
If the base was more solid, i bet this would last longer. energy is being lost as the glass and plastic base deforms under the weight of the disk. at the end of the spin, this might be robbing more energy than low velocity air resistance.
That is so strange to me. The laws of physics in my universe are quite different, and this would be one of those things we sort of take for granted. This type of motion is common place in our daily abouts.
Every time I drop some change in a library.
That ... is damn funny! Genuine LOL

Woah this was 7 years ago, keep up the good work king
wtf
Why I keep finding Seán's 7 years old comments in random videos?
Oh huh
:D
I need to hear a Drop after that kind of build-up...

Looking forward to use this sample pack in my FL Studio
physics.exe has encountered a problem and needs to close.
***** It certainly couldn't be done on OSX, things are too complicated for such an under-powered OS.
It runs on OSU.
(Operating System Universal)
I figured it out.
The Universe:
Windows and Apple had a baby using Ubuntu as a womb.
Some things may not make any sense and seem downright ridiculous, but the math works out. lol
@Willow Rose no no, the laws of physics stopped working
String OS has encountered an issue.
the noise is so beautiful
It's the sound of nature.
you are beautiful uwu
you should listen to some psy trance then i guess
i like how the sound starts building up right at the beginning of the video, and near the end it keeps going up until it abruptly stops. how oddly satisfying.

PowCouse ...maybe o.o
The Sound that you keep hearing is quite amazing too!
When will the base drop?!
CAN I PAINT HEADS AND TAILS ON EITHER END AND USE IT FOR REALLY LONG COIN TOSSES?
The thing isnt flipping constantly. Its spinning on one side.
It'd be cool to see an audio spectrograph (frequency vs amplitude vs time) of the sound.
Somebody get this dude a frickin mic!
Hyperengines engaging, prepare for jump to light speed.

1:24 3D Space Cadet Pinball, anyone?
I loved it!!!
I remember playing that all day xD
YES!
Wormhole be like peeeoowwruudududu
I remember that! I’ll have to check an old hard drive to see if I still have it. Will edit the comment if I can find an emulator for it

One of my teachers used to have one of these. It was really cool... but that one went WAYYY longer than his. That's truly insane!
NOT "insane"!!!!!

Where's the Kaboom? There was suppost to be an Earth-Shattering Kaboom!

VVVVVVVVWOOOOMP! warp achieved captain!
love the sound at the end when it stopped.

The last sound u hear before dying
DEFINITELY

You've seen this when dropping a coin. I once saw this with a manhole cover when the person tried to set it on the pavement without trapping his fingers. It didn't last very long.
This should be filmed and uploaded again at 60 frames per second since RUclips now has that option.
this is strangely mesmerizing and satisfying to watch
idk why but when it stopped I busted out laughing

This would be my totem if I was in the Inception world. Dope
That’s insane 🤣
Did it stop spinning at the end or did it spin so fast you couldnt see it?
1:15 for the good part.
Rotation of the actual disk doesn't speed up, but if you were to monitor the single point of contact of the disc to the table towards the end that single point would be moving around very quickly.
Imagine one of these in a classroom or work place. "sorry, dropped a quarter ... a minute ago"

You're pronouncing it wrong!
It's pronounced YouBluer, I just don't know what I'm talking about...
*****
No, it's pronounced like "oil-er."
That was strangely satisfying.
Can you touch it without breaking your finger?
I hope thats a joke
Learn some physics
Of course you will break your finger, are you serious? The disc is spinning at v=100 m/s and the mass is about 1kg. This combined with its lorentz factor of 5.6 (due to 1/(1-v^2/c^2)^1/2) gives it a momentum of just about 3 meganewtonseconds which is by far enough to break a finger, maybe even your neck...........

For real?....
DeepSpaceBass1 No you idiot lol
Is this gonna be recommended to everyone?
there should be a bass drop at the end!
This effect is not caused by the speed of rotation on the disc, but the speed of the wobble, The actual rpms is probably very disappointing.
The concave mirror causes the the disk to wobble exponentially faster as it tumbles on the curves of the mirror, Really to reproduce this, you need a disc that has some weight and a curved mirror.
Whoever posted that into r/woahtube is my hero!
I was listening to Streetlight Manifesto's Ungrateful while watching this and the spinning noises matched up with the song.
This video made me stressed for some reason.
yeah! My heart picked up pace!
i just wanted to push that piece down and get it over with.
The choppers are coming
Same
I still feel a little anxious
This literally made me so happy
Warp drives,engaged!
It just went back in time! This is a time machine!
Here from Michael Stevens
This was perfect timed to my washing machine spin cycle. Damn it was awesome!
Thanks Reddit.
That's the stroboscopic effect of the camera lens and the rotation of the disk becoming in sync with each other.
EI HOT product of the week:
Do you have one of these yet? If not, perhaps you should get one before they are all gone!
Euler's Disk
We well these at our website. teachersource . com
If you close your eyes it's like a UFO taking off slowly.
this sound gives me goosebumps
Anyone else think this was about to fire a death beam
how many rpms the instant before it stops?
D-D-D-D-D-D-D-DROP THE DISK
This is the best dubstep song I've heard so far.
Dude my heart was thumping so fast, waiting for it to shoot into the sky...
Are they available to buy in the UK as they always seem to be unavailable
......waiting for the bass to drop.....
The end where it stopped, could make an awesome dubstep drop!
Thumbs up if Big Bang Theory brought you here!
how longer this euler disk can spin in vacum????
+Firdaus 2707 The vacuum wouldn't matter much, as slippage is the primary loss of energy.
ok great...
now this is my engine, in basic form.
THIS IS AMAZING.

What if you don't spin it on a mirror? What if you just spin it on a flat surface, like a table, or something?

I love how the sound stops suddenly
Well that was the coolest thing ive seen all day
If the base was more solid, i bet this would last longer. energy is being lost as the glass and plastic base deforms under the weight of the disk. at the end of the spin, this might be robbing more energy than low velocity air resistance.
The end is so satisfying...
i wonder how much longer it would spin if it was in a vacuum?
The way it furiously acellerated and suddenly stopped with no sound made me laugh out loud
Wow. Where can I get a clean recording of this? I can think of a couple of good uses.
This is a dream! The disc is still spinning! We're all living a dream!
This may be weird to ask, but can the trees speak ?
How does it manage to maintain it's energy for so long?
I seriously really, really, really want one of these! So awesome!
Is it just falling like a coin, or does it has a magneto unerneth? sorry for my inglishplz explain to me!
Do they have an exploding version?
So that's what this is called. It's also used to measure annoyance tolerance in co-workers. :-)
If you look on our channel, there is another video of the Euler's Disk.
Such a warm guitar
Reminded me of a hyper drive or something else science fiction based. Awesome.
That is so strange to me. The laws of physics in my universe are quite different, and this would be one of those things we sort of take for granted. This type of motion is common place in our daily abouts.
Is there magnetism involved in this at all?
That's some trippy sound effects.
WOAH! I need this for my time machine.
Euler's disc (temporary name)
how do you get that spin i can only get mine to last around 40 seconds
random725randomness It needs to be on a stable, flat surface, like a hard table or floor.
There is also an ideal ratio between the radius and thickness or mass, and the curvature and polish of the edge is vital.
I hope I'm getting one of these for Christmas
that was so satisfying to watch.
Is there a 10hrs version of this?
حاجه طيبه ... موجود في السعوديه ؟؟؟
so does this make a black hole or something?
We haven't measured its speed/rpm.
this is truly amazing
