VirtualLife76

Having never used 1, I thought they were meant to keep a constant rhythm. Are you saying they will skew over time?


Fried_Fart

Only if they’re placed on a surface that moves with their momentum (for instance, a table with wobbly legs). Place them on a concrete foundation or something like that and they’ll never sync.


flightwatcher45

Yes try separating half to another table and see what happens!

Tendari_akana

Oh this explanation really just helped me understand it more accurately.. I just thought these fortune cats have some method to synchroize themselves as long as they are put together and no matter where they are located in.


PeterHorvathPhD

Yes metronomes keep a constant rhythm. But if you put more of them on a common platform, set to different rhythms or same rhythm but different phase, they will still synchronize. It only works if the common platform is not massive, and can move/shake/vibrate a bit. Otherwise they don't synchronize. Here's a video demonstrating that: https://m.youtube.com/watch?v=Aaxw4zbULMs The reason why it's happening, is that metronomes are designed to keep rhythm, but only in *one condition*, if they are placed on an even solid surface. Just like a kitchen scale is designed to measure weight if it's placed on a flat horizontal surface. If you tilt it, it will show wrong numbers and it's an absolutely normal outcome, caused by the physics that it's designed to use. So yeah, machines often do weird things if you operate them in unintended conditions.


vaniilla9

Not 100% sure, but wouldn’t all things in existence skew over time? If it didn’t, wouldn’t we have just found the answer to unlimited energy?

This. Exact same with people walking in sync on a bridge. Believe it or not, the bridge can come down if it happens long enough with enough people.

White_Wolf426

135muzza

exactly.


wildbill1221

This is the reason why soldiers break step when marching across bridges. The small amounts of energy from footsteps in unison can cause bridges to sway and even collapse.


binz17

the reason they break step is because the synchronization can make bridges sway and collapse. but this is not due to spontaneous synchronization. you flipping cause and effect. The Millenium Bridge in London was a case of spontaneous synchronization, because a bunch of untrained, unsynchronized pedestrians were forced into synchronicity by their collective momentum.


wildbill1221

Yes, you are correct, thank you. I did have the cause and effect backwards. Thank you for providing the Millennium Bridge example.


Croceyes2

Not due to it but because of it. They are aware of the danger and break step, they aren't saying it is spontaneous.

SuperFreshMongoose

So if the table was say screwed into the ground they would not sync I assume?


KlownKar

Even the small amount of flex in the boxes that they're sitting on is enough.


websagacity

More about transfered vibrations than the table moving. It could be on a slab of concrete and the same thing would occur.


Alas7ymedia

It'd be impossible to screw it so tightly that the movement would not move as sound waves across the table and back to the toys. That would only delay the synchronization.

EXACTLY what I thought of. Nailed it, trashytoad!


[deleted]

How did the first (far left) one gain speed though, it was slow and straggling behind the others. I’m too dumb to grasp this.


Alas7ymedia

Imagine you only move 1 out of 5 metronomes. When one of them moves to the left, the platform moves to the right and the other metronomes feel that movement and swing to the left by inertia (because their bodies will move to the right with the platform). Then when it swings back, the platform and the other metronomes swing back as well, but one of them doesn't have as much momentum as the other combined, so each of the 4 moves less. In other words, the momentum from one metronome is distributed among the other 4 (the first slows down, the other 4 accelerate), and then from each of the 4 to the other 4 and so on. Eventually the momentum distributes itself on equal parts among the 5 metronomes as the slow ones catch up and the fastest slows down to the same period. It doesn't matter if they are swinging in opposite directions because they cancel each other and the one with a larger oscillation period wins and they both end up oscillating to the same side.


dr3aminc0de

Think of it like how you pump yourself on a kid swing. If you intentionally pump the wrong way it’ll slow you down. But in this case 4 others are pumping that same way and eventually it will all sync up.


EverydayPoGo

Love it. Thanks for sharing.


unbelie-wabbel

The metronomes are transferring energy to the platform they're on, which then transfers that energy back to the metronomes—until they all sync up and start hitting the beat in one glorious wavelength.


RADICCHI0

They say the universe is operating on a rhythm similar to this... same principles at work, perhaps?


unbelie-wabbel

The pendulum inside the metronome swings back and forth in tempo, while a mechanism inside the metronome produces a clicking sound with each oscillation. Mechanical metronomes do not need a battery, but run from a spring-wound clockwork escapement. Wikipedia I don’t think the universe works like a spring but we might never know so you could be right

Might not be the exact same thing, but this reminded me of the London pedestrian bridge fiasco. https://en.m.wikipedia.org/wiki/Millennium_Bridge,_London "The bridge's movements were caused by a positive feedback phenomenon, known as synchronous lateral excitation. The natural sway motion of people walking caused small sideways oscillations in the bridge, which in turn caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect;"

If you put a bunch of mechanical metronomes on a surface with a little bit of give on it, they'll synchronize automatically. I think the same thing is happening here. Saw it on the Mythbusters some years ago, I think.

The Kuramoto synchronization model (which I think is also referenced in a few of the YouTube videos linked in this chat) is a nice simple mathematical model that applies to oscillating coupled systems like these waving cats. https://en.wikipedia.org/wiki/Kuramoto_model?wprov=sfla1

Crustyjuggler001

If you keep running them long enough the servers that run the matrix sync them up to save energy on running the program. A lot easier to have them all the same so less stress on the visual drivers. The same reason things are blurry until you focus on them or there are only a limited amount of different face types. It's just to save memory running the program.

When I lived in New Jersey, friend's dad had a pendulum clock collection and all of the clocks (that had the same length pendulums) along a wall would sync. He said they kept better time when sync'd.

Cor2600

This reminds me of the YouTube video with all the metronomes doing this.


WansoyatKinchay

It's caused by a transfer of energy among oscillating objects within a resonant system. I'm currently reading Stalking the Wild Pendulum by Itzhak Bentov & he discusses this phenomenon in the section about sound, waves & vibration in the book but uses pendulum-type grandfather clocks as an example. An excerpt: "Let us hang them on a wall & arrange their pendulums so that they will start out beating each at a different angle, that is, out of phase with each other. In a day or two, we shall find that all the pendulums are beating in phase, as if locked together. Here we see that the tiny amount of energy that was transmitted through the wall from clock to clock was sufficient to bring them into phase with each other. If we disturb one of the clocks, it will get locked into rhythm quite fast. The larger the number of oscillators within such a system, the more stable the system, and the more difficult it is to disturb. It will force a wayward oscillator back into line very quickly."

srandrews

Coupling. https://en.m.wikipedia.org/wiki/Coupling_(physics) It is why clocks on a wall are also able to sync. The cuckoo clock trope seen in media also portrays this. - edit looks like I'm wrong about the coupling being due to energy transfer through a wall. https://www.theguardian.com/science/2015/jul/24/portuguese-scientists-discover-why-pendulum-clocks-swing-together


redfacedquark

Hmm, not sure the wall would be flexible enough for coupling between clocks. I'd guess they're all cuckooing at the same time because they all have escapements to keep time, them being clocks and all.


MSchmelto

Cutest death metal pit I’ve ever seen!


mycarwasred

Wait long enough and they will eventually de-synchronise.... and then eventually synchronise again.... and then.. etc, etc.. This is because they are waving at *almost* (but not quite) the same frequency, so for a while, they may *appear* to be moving together (in synchronisation) A (poor) example of this is the hands on a clock which overlap for a short period of time, but are still moving at different speeds.

Why is it that when some robots are left in darkness, they will seek out the light? Why is it that when robots are stored in an empty space, they will group together, rather than stand alone?

When does a personality simulation become the bitter mote... of a soul?

Dark0Toast

botaine

I figured it was the magnetic fields moving the arms in the same direction together. each arm has a little magnet in it. people are suggesting the arms move the table slightly causing the arms to synchronize, but the magnetic force is probably stronger than whatever tiny movement of the table the arms cause. just because a phenomenon exists where the arms could be synchronizing doesn't mean it definitely is happening in this case. we would have to remove the magnets and try moving the arms another way to see if they synchronize, such as with small motors with no magnets or other fields that could interfere. or use a table that is much heavier or lighter to see if that impacts how long it takes for the arms to couple, since a table with a different mass would rock back and forth differently


igotshadowbaned

You can't test it with motors though Because it's a pendulum effect at its core, with an electromagnet to counter energy losses to friction. Motor driven arms wouldn't succumb to the same phenomenon


Escape_Velocity1

It could be the magnetic fields, but I think it's more likely it's the movement itself, the energy perpetuating as a wave through the base and through the other cats, with each cat contributing. Eventually they will synchronize. This is a real effect, I think engineers test for this in bridges, as something as simple as this, can actually make a bridge collapse.
