how did i got here from modal logic and systems theory under determinism?

[nosnibor800]

Interesting. Can anyone explain why it happens. Injection locking can be used RF and is the principle used behind homodyne receivers and I think in super regenerative receivers.

[ThoseWhoStayUofM]

@nosnibor800 recall from introductory mechanics that linear oscillators have fixed frequency given by system parameters e.g. for pendulum f = sqrt(g/L). In fact, this is simply a leading order term in an expansion about a small amplitude. In synchronization, nonlinear oscillators adjust their period by changing their amplitude. The non linearity of these metronomes comes from their large amplitude and the drive mechanism which injects energy into the system.

I hope this explanation helps.

[ChrisArnol9010]

@nosnibor800 Excuse my simple mind but.. in standard English please?

[strugsnotdrugs]

This is amazing!

[bigbluemusic]

Explains why most drummers improve on a couple of cans!

mmm, that research article link in the description only takes you to the latest issue of the american journal of physics. anyone got the right link to the paper?

[BigCheez8682]

Where can i get a metronome and how much does a single one cost. someone please answer

[luckeycat34]

@BigCheez8682 uhhh.. i would try a music store..

[ssslawek]

@BigCheez8682 music store, 99$

[BigCheez8682]

@ssslawek are there some cheaper than that

[ssslawek]

@BigCheez8682 I am sure there are, from $10 to $1000 and more, I paid 99$ 10 years ago for wooden Wittner.

there many kinds, clockwork and electronic ones. those in the video cost probably 29.99 each. Check the ebay.

[BigCheez8682]

@ssslawek ok, thanks

[shakespeareaholic]

fake AND GAY



[wolfson109]

@shakespeareaholic If you think it's fake, try it yourself. It does work.

[silvestro771]

coupling forces "synchronization", but why synchronization is a more "stable" condition with respect to non synchronization? Not clear at all to me !!

[pieperx]

Brilliant!

Thank you very much for posting the video!

Exellent explanation for who that want understand what a synchronization is. I'm an electric technician and I compared the metronomes synchronization with AC synchronous machines- the principle is the same.

this is giving me a headache

This is nonlinear entrainment, not synchronization.

@dogdove did you try resting it on some cans? Perhaps kegs will work better?

[Akins560]

that is triiiiiippy!!!!

[RUOCCOLOCO]

looks like when I practice with my band... sometimes we are together and grooves nice and even?

[Esebi95]

I feel like I've been hypnotized

[deadlybug]

what did i just watch exactly?

[RobertHaraldsen]

This is actually a demonstration of how the "damper" (essentially the board) of the different oscillations is transferred between the metronomes, and should perhaps be referred to as Injection Locking.

[luizvilarinho]

o experimento tem que ser feito de pijama, senão não funciona.

OK - now the tough question - how would you calculate the time required for the metronomes to synchronize within a given tolerance?

I liked the bit with the metronomes? Don't take any more of that

878 people dont know what synchronization is.

[TonyTube407]

Pretty cool!

It sounds like a horse.

Or someone banging 2 half coconuts together.

[Fuzzycop]

@MrBarry1024 ...but where would they get coconuts in England? Carried by a European swallow? d;)

[bendo9521]

Very cool.

[SloppyLarry]

Is this an example of common relativity mixed with kinetic energy?

[sparkloweb]

Did you just have 5 metronomes sitting around or...?

[Hackepeter42]

Its not the Pendulum making that sound, there are horses behind the camera :O

[AvengerSeraphimon]

@Hackepeter42 thats what i thought at first xD 2-3 horses galloping around xD

[flashguy234]

ho , lo q veo es que los balances de cada uno cambian( siendo todas del mismo peso)... al ser mas rapida la

compensacion de movimiento de la base con las latas, mandando el peso al lado contrario del movimiento generado, y quedando syncronizados muy interesante movimiento angular

Altogether now!

[MustNotRead]

that's a pretty amazing phenomenon.

[Zorn101]

Entrainment is the process whereby two interacting oscillating systems, which have different periods when they function independently, assume the same period. The two oscillators may fall into synchrony, but other phase relationships are also possible.

Now what dose this mean for brain waves and Heart beats?

[IBIoIMIbIEIr]

its dumb. A first grader could have done this. The cans let it roll which moves the board take the momentum through the pendelums. easy

[indumamoon]

Wow that's incredibly cool! It's truly mind-boogling to try and understand how it works haha :D Thx for sharing!

[Deadlywaterboy]

stumbled from the next room over. someone left some shit on the floor

[dentedface]

how is that possible? it seems like that would require changing their paces.

[tret32]

the rolling of the cans must use the momentum of some of the pendalums to synch the other ones

[luluBluStar]

E' sorprendente vedere dal vivo questo esperimento

Avevo letto che anche gli orologi si comportano nello stesso modo

[VideyoJunkei]

the coolest thing to me is the fact they synch, then unsynch several times before setttling down!

[hawkfish88]

Stumbled from Lancaster University lol

[bobdahaxor]

This is actually a demonstration of damped harmonic oscillation. The metronome needles are at the same speed & the only variable left is time. When he adds the board there is a transfer of angular momentum because of the phenomenon of Angular momentum as a generator of rotation. As the soda cans move, angular momentum is being transferred from the needle, to the system & cans. This transfer of angular momentum is the damping force. This & conservation of angular momentum makes the needles sync

[morecambe13]

Does the fact that he uses an odd number of metronomes enter into it? If he were to use four or six, would their motion exactly cancel each other out, and destroy the synchronizing effect?

[bobdahaxor]

Not at all. It's specifically called the entrainment of frequencies. Where there is a forced vibration on each other. They then "lock" in time with a lower frequency afterwards. Hense the movement of the cans due to the conversation of angular momentum. Sorry if I was unclear before. I forgot the name of the phenomenon. Also, WHO PUT -1? Guess you don't know what your talking about

[DKsasquatch]

@bobdahaxor This is sarcasm.

I always watch the indicators at traffic lights to see when they synchronize. Very interesting.

[yascumbag]

they only all synchronised because of the rollers underneath

eventually they all compromised and went with the sway of the rollers if he had left it on the table they would have not synchronised still clever tho just wonder if theres a pratical application for this knowledge!

stumbled from honolulu, hawaii. phasing metronomes! check out steve reich.

[ladyla32613]

were the all put at the same tempo, try putting multiple ones at a different temple eventually it cycles around that one click will have them all be together, then it goes out of time again. kind of like this but it doesnt stay in sync for as long.. i think anyways im not a medical physicist or anything, just a percussion that plays with metronomes when bored.

The cans have nothing to do with it. They're just used as a way to hold up the board while letting it sway freely.
