If you're going that far to stay in time with each other, you should try practicing more. :P
@@edwardssistershands Believe me, in middle school band no one practices.
Wheely?
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.

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.

Interesting! Even the metronome on the far left gets in synch with the others. More interesting yet is the how the far left metronome acquires more energy, so that it's period of swing becomes the same as the others, even though it started out slower. I wonder what would happen if the weights on the metronome arms were adjusted such that 2 metronomes had the longest periods, and 2 had the shortest, and the other 2 were randomly set.
Probably the same being as the applied force on the board and the cans as casters are the stabilizing mechanism that links up to the cans having synchronization.
Синхронизация почти невозможной,но само стремление к синхронизации будет безпрерывным.. войдёт в подходящий такт- циклов.. которые будут постоянно повторятся ..
You will have an average frequency of oscillation for the plateform.
Then the more the frequency of à metronome is closer, the more it will have a higher level of oscillation, the more the frequency is far from the plateform, there wil be non sync interactions that will lower the level of oscillation of the metronome.
It can become complex because every change in the level of oscillation for some metronomes with z given frequency should change the average frequency.
You could have a chaotic system.

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.
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.
Someone: Why do you like physics and mathematics?

The left one is me trying to repeat the moves that I don't remember after others during the group dance
In the end, you succeeded it seems though.

what if there is a moving platform
@@alexwu69700 the earth is rotating
haaaa good one foxey I was about the same thing
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)
@@Marcten10 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”
@@Marcten10 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

Shoutout to the one metronome that refused to sync up and kept its own beat for as long as it could.
Don't feel bad man, peer pressure is hard to resist.
The sound of the audience's applause at the end of a performance resembles the sound of waves, with each rendition at a different tempo, but soon everyone clapping in synchronization.
The movement of the ground reflecting the reciprocating force of the pendulums of these metronomes eventually made all the pendulums of all the metronomes synchronize into a single rhythm.
As I'm a musician, I believe that all repetitive motion is circular motion, and that drum rhythm is an expression of gravity.
Real musicians play inaudible sounds and feel invisible things.
"What is he doing?"

😂 not bad not bad
Ha ha ha!!
This is the matrix. Anything can happen, lets just hope that the smith program doesnt come back again 😳
Lolll
This very comment just made my day, thank you.
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.
for some reason this always amazes me i just love to watch it happen when my dad turns on his blinker and it starts to match the car in front of us
when you don't want to dance with everyone, but the music just gets you...
There's nothing spontaneous about this. Put these metronomes on an immovable surface and they don't sync

No drummers enter the chat
So the band always does this until the conductor gets it right
Made me smile even knowing it would happen.
It's an equalizing of forces applied by the metronomes. Since the platform under them is moving that force is being enacted on all the metronomes by the metronomes.
We all have that in common...
We have no idea why is this in our recommendation, but we found it interesting anyway

For the sake of knownness, the mathematical model describing this behavior is the Kuramoto model.

kuramoto is an abstract synchronization model. This behaviour is modelled uisng some other coupling terms. If I remeber correctly, they have coupling terms similar to Vanderpoll oscillators.

so what do you learn from that.
i have no clue.
@@zoomatazoo3520 You learn that if you were inclined to find out more about it, it would now be easier to search for the information.
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

Ditto
Same
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?
I think that when we feel pleasure, and we get what we want; it is because it is synchronized with the properties of my personality and how we operate mentally. What you love is what defines you and your interests and what you support, not what you hate and what harms you. Harmoniousness = Pleasure
This is so satisfying. It just *feels* right.
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

Resonance, they say.

Why did I start bobbing my head along with this?
Anyone not sure how this happens, look at what their on.
Each action has an equal and opposite reaction.
The force of the moving arm imparts the opposite action to the base.
Since there are five of them this action is the sum of all five arms.
To begin each is in a different phase, this makes each interact slightly differently with the motion of the base. Slowing or accelerating the arm.
In time this interaction will cause each arm to be in-phase with each other.
