Hell, I've already seen this.
Like, five years ago
For those of you interested in the "why". There are an odd number of metronomes. This makes sure there's a force greater in one direction as 3/5 metronomes will swing that way. This exerts force on metronomes that aren't moving that direction, nudging them backwards from their momentum. This slight nudge backwards counters the pendulum effect causing the metronome to move further towards the side with greater force. Over time this will cause all metronomes to synchronize to the greater force pendulum. If you were to do this with four metronomes it might get interesting as 2 are going left, 2 are going right, but eventually friction in the bearings will force a side.
No. It's magic.
As someone with a masters degree in physics, I agree, it's magic
In english please.
Oh ok, this actually makes a lot of sense. I didn't really understand how it was possible but I get it. That's really interesting.
@@username-ql8ox Either that, or it's those cans.
It's cool how the 4 on the right are lending some of their energy to the one on the left. Watch the left one. It has a smaller swing than the others and gradually gets greater until it matches the others. For anyone not understanding this the cans and board are the key. The board shifts slightly back and forth dampening some while adding energy to others until synchronicity is achieved.
I figured that energy was being shared among them. I thought, put them in different rooms all in earshot and I bet they don’t synch. 🤔
@@alextownsend6662 What does earshot have to do with it? You could just remove the cans from the bottom and they wouldn't sync like this. It's the motion of the board that causes the synchronization, the energy of motion is what is being referred to.
@@Alexander_Grant so you can hear it
Synchronization. Synchronicity is inexplicable coincidence. Synchronicity is a made up thing; physics is REAL. Mostly.

Oh goodness, I thought it was just me paying attention to synchronised blinkers 😁
Definitely!
If I had to guess, the swinging of each metronome got transferred into the plank they were balancing on, which slowly sped up and slowed down each one until they swung together.
Yeah pretty much.
Yes. It's all about transfer of energy. If the metronomes where simply placed on a flat solid table they would NOT sync up. It's the rolling platform underneath them that "evens" out the energy of the metronomes above.
@@utube9000 Actually they might still sync up, through tiny vibrations and shifting of the table. But it would take a long time. If they were placed on an "ideal" table that did not move or shift at all then they wouldn't sync up.
No. It will happen regardless of the swinging base, it may just take longer to happen. Grandfather clock pendulums will synchronize, clocks in a clock store.
Its from a morphogenic field.
In nature you see it with schools of fish swimming in unison, and flocks of birds. All moving as though they are of one mind, making movements far to quick for each single animal to be independently sensing and making assessments at every fraction of a second. That would be impossible.
Its morphogenic fields.
Its also how homing pigeons navigate.
@@JoshPhoenix11 I can assure you that no 'morphogenic field' is happening here. What you are seeing is physics.
It's amazing how the amplitudes eventually sync as well as the frequency.

@@TheDanubeDepleter
No, too pendulous an answer.
I feel like this is the kind of discovery someone could have made only because they were bored out of their mind one day
Like the guy who decided to sit under an apple tree.
I heard someone discovered it, cuz he watched 2 pendulum clocks getting synchronized like that while trying to sleep and then tried to unsynchronize them
It was discovered by the guy who invented the pendulum clock (to help sailors keep time with land for navigation purposes) and while he laid bed ridden with some illness or broken bone or whatever, he noticed that two pendulum clocks when supported by the same beam would slowly synchronize regardless of their starting position. So yeah, pretty much.
@@05anonymous50 i think he was quarantineing from a big outbreak, so he probably was pretty bored
Well the man who discover this thing was bored and watch a clock for an hour.
And through much dissonance the mastermind was born.
The energy at the top of the movements is dispersed down into the table (besides the normal constant forces acting against them) and because they all move with the same frequency of motion their transfer of energy harmonizes. Like ripples that overlap but eventually join into one larger ripple/wave.
This is the definition of "Oh yeah, it's all coming together"
Synonym is "wtf? how?"
Exactly🤣🤣🤣🤣🤣🤣🤣
dunno 'bout that but they should be playing 'come together' on this and maybe some small paper puppets attached to the swinging arm...just saying
wtf.. I literally was just suggested and watched that video RIGHT before this one...
No
Damn, i saw this video a few years back and had no clue how it worked (was like 14 at the time) but coming back to it with a degree in physics i can confidently say i still have no clue whats going on
Its quite simple. When one of the metronomes swings a force is exerted on the bottles below which causes them to move. When multiple does that it moves in such a way that the small forces exerted on the bottles slightly alters the swinging motion of the metronomes until they eventually synchronize with each other. I have just gotten started in studying physics and could easily figure that out cmon dude.
@@antenym8947 i know😂😂 i just thought the joke would be more funny if i said i had no clue
Also you would get a 1/3 for that explanation because it’s actually a frequency system with each metronome applying their frequency to the moving beam causing the beam to have an average frequency that it then applies back to the metronomes equalising till everything has the same frequency (tbh even my explanation is still not complete since i study physics to be a teacher rather then a researcher)
@@Metal-and-Mythos You would get 2/3 for that since you failed to mention anything about energy
@@rykehuss3435 what energy? Although it can be explained using energy theory when explaining it with frequency the only energy in the system is in the frequency and thus you can use frequency instead of saying “the frequency of the metronome uses its energy to apply movement to the beam which changed that movement back into energy to change the frequency of the metronome” “better wording would be “metronome 1 applies its frequency to metronome 2 using the beam as a medium”
@@Metal-and-Mythos Takes more energy to go against the grain so to speak, so the metronomes out of sync lose it constantly until they get in sync
When this was posted ten years ago it explained a lot, it still does, but it did back then too.
I'll bet the mathematical function that represents that damping oscillation is even more beautiful than the physical appearance of the thing.
The left one is me trying to repeat the moves that I don't remember after others during the group dance

Synchronization*
the cans rolling underneath create the synchronous movement.
Why did I start bobbing my head along with this?
If anyone wonders how this works: the rocking of the base provides resistance for the swinging arms, which slows down their motion in the opposite direction, and propels it in the correct direction. It's like continuously nudging someone the right way when they're dizzy.
Thank you. I saw this too and wondered if this should be call spontaneous when it truly isn't. But everyone else it's talking about its beautiful rhythm
Garcias amigo .
How about other situations like for example, one day I was sitting on my car with the alerts light turned on. The car right in front of me was also with its alert lights on and every now and then both them synchronizes.
Is there a possible way where both of alert lights were affecting and /or interfering each other?
I really watch that kind of sync many times in many different situations

@@computerscience2589 metronome
He's not taking about a metronome, he's talking about the various drums and cymbals.
in terms of trying to get all your limbs to communicate together on a beat, it's typically a little messy til you get tighter.
@@parkerdavidson5868 honestly I think that the harder part is having each limb do its thing
The explanation for this is that the vibrations and kinetic energy of each metronome is transferred into the surface below which moves depending on the net force. This same force is disturbed back to each metronome. The most stable energy state is when they are all in sync with each other and not conflicting each other’s movement. When they eventually reach that state, they can’t get back out the cycle since it’s the most stable.
Yup, resonance
@@lordjogonnath6580 exactly. The cycles of simple harmonic motion.
Oh thanks, I was wondering how it worked
And here I was thinking about entropy. Huh... Neat.
Would this happen on a base that was firm and stable?
What amazed me was someone owned 5 identical metronomes
It's a physics department...
You are who you spend time with !
Beautiful.
It is important to note that the synchronising effect is communicated through their common base. The 'stragglers' are nudged into sync by the momentum of the 'increasing majority'.
Mythbusters did this with a bunch of these . More than a few of them would not synch.
Yup I figured that was the reason as well, does that mean I'm not as dumb as I thought?
I know you meant well, but I feel even more dumber right now

Any kid who's ever "boosted" someone on a trampoline gets this phenomenon intuitively.
or *been* boosted, lol.
Being boosted is the most terrifying yet thrilling thing in the world
I hope it was as much fun for these metronomes.
I may not understand how it works when actually being the one to *witness* this phenomenon, but I DO understand, if only in application instead of theoretical, how boosting someone on a trampoline works, so I agree with very much so.
Resonance, they say.
What an elegant demonstration of an obscure sounding physics concept.
If only school had been more like this....

A really good, inspiring teacher is SO important.
I was fortunate to get the Science Master in my senior high school years and he was so good that I ended up doing a science degree with a chemistry major.
Sadly, school is a long, drawn out pitch battle that tends to make hacks out of many teachers and students alike. They say Finland has a better approach.

@@RonJohn63 I see the same. Those pendulums whose in-sync with the board rocking thus also creating opposite force on the lesser numbers of the pendulums whose are not in-sync, these then slow down due to that rocking force against them, then move with the greater number of pendulums,. At last, they all synchronized with the rocking board, that is the least or no resistance to them.

When you’re waiting to make a left turn and your blinker clicking matches up with the blinker of the person in front of you.
My immediate thoughts
Yes
Safda yurishni oʻrganayotgan askarlarga oʻxshar ekan💯🇺🇿
I think this happens because the metronomes average out one direction, so if three swing left and two swing right, the average is swinging left, causing the platform to move in that direction and weaken the rightward swinging of the two metronomes. Eventually, those two are so weakened that they stop entirely, but then the motion of the platform causes them to swing again, this time in the direction of the other metronomes, thus causing them to sync up.
This is just a theory though, I have no way to confirm or deny this, but it makes sense to me.
So this is where UA-cam takes me when I look for “how to figure my life out”
Get together with buddies that did and let synchronization works its magic ?
