Spontaneous Synchronization

[fireelementaldemon]

lmoa they look like a bunch of dicks hahahahaha

[crpygmalion]

are they set to the same tempo?

[SamEvensenMN]

the pop can rocks it back n forth. its cool though

[cugel2]

science roolz

[JandritoBlues]

Will they stay synced up until they all stop? Or will some stop before the others?

[e7w58h]

uninspiring...interesting for children perhaps...

[Ceyezas]

Unfortunately, no matter how cool this actually is, they become synchronized because of the fact they are all on a single flat surface and the momentum from the rest of the tickers makes one sync with the other and the rest follow in suit. I still quite enjoy this experiment. 5*

[GeoffM1990]

This is similar to the Tacoma bridge incident.

[run4flat]

Actually the Tacoma bridge is quite different. In that case, the bridge responded resonantly to the driving wind. The over-arching theme there is resonance. Here, we have self-organized synchronization and resonance doesn't play any role. You are right in that both show organized collective behavior, but the underlying driver of that behavior is entirely different.

[SidewalkFrequencies]

who gives a fuck.

[Jettblackmatt]

man watching those metronomes are hypnotizing.

[DesertedBaby]

*flashes subliminal message* >:)

[1french]

It's not really spontaneous when they are effectively linked to a feedback system

[Oliverstwist11]

@1french

[sonuccard]

wow, if you don't know how this works by just watching your an idiot. I mean really?

[luckyw4ss4bi]

It doesn't really work. The video's fake, we did it in my college science class. You're an idiot

[Kalywonkas]

I'm willing to bed you're going to a collage that has TV adverts...

[luckyw4ss4bi]

bed isn't a verb, noob

[Kalywonkas]

Well, while i did admitedly mean to say bet, technically bed is a verb and a noun, it can be used in the context of, "Let us to bed," Meaning "Let us go to sleep," Following the same line of thought, "I'm willing to bed," Also makes sence. Before critisizing, learn to speak English, oh, and if you were wondering, no i'm not in collage, i'm 15. Good luck getting anywhere in life when 15 year olds outsmart you.

[smashbrawler]

Ahhhh I can't help myself!! While your intention is correct, bed can indeed be used as a verb, your example isn't. In that context bed is still a verb. It is only excluding the word "go," as in "Let us go to bed." For an example of it being used as a verb, consider, "I will bed you." Also, don't advise others to learn English when you yourself can't spell "criticizing," "college," or "sense."

[9Psychoticaly1Yours1]

im willing to go to bed

i am rather tired right now

[Rithoy]

You spelled "college" wrong.

[99rhetbaboons]

Neat.

[LizMarshy]

I know what you mean.

[stanklikedank]

resonance...

[autopsi]

This is not spontaneous...

Spontaneous : happening or arising without apparent external cause

[faithm]

yeah i was going to say that too. its a matter of balance.

[puationstation]

equations please...

[Eralen00]

lol!

[01cwarr]

entrainment is the correct term for this phenomena

[AICorp]

This works because they start moving that board they are on back and forth. Once two of them are going at the same speed they cause the board to move with them, the board moving causes the other ones to move at the same speed as the board. Ergo, they all go at the same frequency.

[jtriffo]

nice use if ergo, most people dont know how to use it... not that it matters though, most people dont know what it means...

[AICorp]

yeah lol it is nice to use when appropriate, makes me feel smart to say it. Also save soem characters when posting on you tube (As opposed to typing therefore)

[jtriffo]

hmm, it does save you characters, see you dont just feel smart XD

[88ale]

This is the end of the world

[physixroxatl]

Will you share the equations of motion please?

[LeonSzillard]

artificial intelligence

[lollerskates1990]

nice

[nikkilicious17]

yeah basically haha

[SambaDisaWinner]

haha yehh i watched that one as well yesterday

[CllnSage]

me to, I didn't finish the tap dance thing though

[nightfall91]

crap

[SambaDisaWinner]

I bet everyone is watching all these syncronisation videos on the related videos from the featured video righttttt?? lol

[SaileAway]

haha, yup

[SambaDisaWinner]

yehh thought so lol we all do it

[marredsun]

haha. good call. Who knows what randomness we'll be watching 15 minutes from now? I like to leave the first video I watch in a session open in a seperate window. When I'm done YouTubing I try to mentally recall how I got from the beginning to the end.

[naarrd]

haha sammmmmee

[SambaDisaWinner]

Im surprised how much conversation i started on this video lol

[carloslorini]

me too!

[naarrd]

yeahhhh

[airdreamlove]

No, as long as the weight of the cylinders remains the same in my opinion.

[vaultmantk]

if you used a cylander with a bigger diameter, would they sync up quicker?

[SaileAway]

I think so. A larger circumference would provide a larger 'rock' for the same amount of rotation.

[carlpaulsen]

I always place mine on beer cans. It seems to work better.

[goodcommentguy]

strange, it's always on soda cans

[pr0n3]

I wouldn't call it spontaneous...more like the law of conservation.

[blaccprodigy]

Without the use of Stumble upon I would've never found this cool random video (i don't literally mean random because there's probably a whole league of people who take this real seriously who would punish me in synchronized type torture)

[SculptusPoe]

You could force the lot to go into any resonance you wanted by grabbing the board and moving it with your hand in the beat you want them all to move to.

[SculptusPoe]

Look at one pendulum. When it swings to the far left and changes direction and moves right, the pendulum pushes itself to the left. Because they are all attached to the roller, the bodies are all pushed left. This dampens the pendulum weights moving to the left and accelerates the ones moving to the right. As it tends to cause the entire set to have the same net damping in the one direction, eventually they reach a stable point, which is where they are all in sync.

[zaxt3r]

no shit, sherlock

[Septimius]

I love stumbling across stuff like this.

[fffjjjnnn]

you too? its the best aint it

[Septimius]

Haha. It really is.

[greyerg]

Yep I was here too.

[zaxt3r]

StumbleUpon FTW

[TurtlesTheClown]

this is sparta? how does this work, because according to life ,that shouldn't ever happen...

[SasquatchKiller]

No, it should... it's called resonance. Each metronome provides a driving force to the others once you take them off a fixed surface kind of like a kid on a swing. Look up coupled resonance for more info. Neat nonetheless, seen it done with clock pendulums before.

[Punkirudeboy]

I love when you learn science by reading youtube comments xD

[zaxt3r]

lol never before, never again

except the Ruben's tube, you gotta see that one. just search it, there's a good 6 or 7

[effyleven]

Well.. that's a remarkable thing.

I didn't know it happened.

[ThisisThelma]

What are the implications?
