My best guess is that there are 2 factors that made the outlier stay strong for so long: 1. horizontal movement acts weakly on metronomes that are nearly in phase or nearly exactly opposite, 2. due to pendulum motion of both table and metronomes there is also a (weak) vertical component of table motion with twice the frequency that stabilizes not only metronomes that are in phase but also those in opposite phase, but since it‘s so weak it needs precise alignment of everything (or just luck) to get a metronome locked in opposite phase despite the horizontal movement trying to destabilise it
it's just the vibration from all the metronomes on the flimsy table that ends up syncing them all up. if you tried this on something more sturdy like a concrete table, you most likely wouldn't get this result, at least not that quickly.
Same thing happened to the millennium bridge in London. Bridge started to sway a little bit, eventually people unconsciously stepped with the sway which only increased it. They had to shut down the bridge to apply dampeners due to the massive forces so many people stepping in unison was doing.
For what the video says (and I can understand) this is an experiment about synchronicity. What I think that happens is that the table starts moving slowly when the metronomes start oscillating... maybe it's the oscillation of all those metronomes moving the table (which seems as if it's hanging), movement which, later on, when it's gained some energy, help synchronize all the metronomes
if you accelerate the metronome one way, it slows down when it tries to swing in that same direction. The surface is probably suspended by strings or something which is why you see it move around, so the metronomes momentum naturally force the other metronomes to come to a closer position, making them sync.
For the lazy, a rough Google Translation: Metronome synchronization (32) When you move the metronome and put on a table that moves multiple metronome that ticks all the metronome sound at the same time as it is known in sync eventually. Create table test equipment such as works by hanging from the left and right units to put a metronome, the laboratory is Ikeguchi, we have conducted an experiment in sync. In this video 32 metronome ticks sound at the same time.
That one fucker in the second row on the far right just kept us waiting longer than it had to be. There's always that one, who's the special one, right? Wasting everyones time fucker... ;)
They would be synchronized also not on a mobile platform, but it will take something about three days. And If you have more metronomes, your have more faster synchronization.
Hi Rebecca, If you watch closely, during the initial startup actuation by hand, the right column second row starts moving before it is even touched. This occurred because the close mechanical coupling through the movable table base has already become so strong, as to self-start the last of that metronome and others.
It is the combined motion of the metronomes that causes the swaying that gets them all in sync. Once the table starts swaying, by the combined motion of the metronomes, a harmonic frequency begins to control the metronomes, knocking them out of their original pattern and aligns them to match the frequency of the table they rest on.
Они бы синхронизировались и не на подвижной платформе, но для этого им понадобилось бы дня 3. Причем чем больше метрономов, тем быстрее они синхронизируются. Это явление называется синхронизацией динамических систем. They would be synchronized also not on a mobile platform, but it will take something about three days. If you have more metronomes, your have more faster synchronization. This phenomenon is called the synchronization of dynamic systems
oh yes they will, just really slowly. watchmakers have noticed this pretty early in history, when they put pendulum clocks on the same wall, and after a couple of days, all the pendulums got synchronised
You are correct. The table isn't swaying rhythmically at the beginning of the video. It is the combined motion of the metronomes that causes the swaying and helps get them all in sync.
wow =D It's amazing how connected everything is. Much like when scientists try to isolate a crystal for the first time. If 6 scientists in 6 countries doing 6 different attempts to isolate something in crystal form are working, and 1 of them successfully isolates, then it becomes easier and faster for the other 5 scientists attempting the crystallization to succeed! So amazing!
They disproved a different bridge design with the badly timed pneumatic shoes that only go up and down on a badly scaled bridge. Basically their designs were flawed but I doubt they had the budget or time to test what caused the "real" problem. Their feet had no sideways force. They were only testing vertical oscillation, not horizontal.
Basically, every time the little pendulum changes direction, it exerts force on the board they're all sitting on. That jostles the board, and the board jostles the other metronomes. They all feed back on each other until a predominant force wins out and begins shifting the board primarily in that direction. It's harder for the metronomes to swing against the sway of the board than with it, so they all eventually end up swinging with the board, and, by extension, each other.
@@billduris464 (9 years ago) This comment was written in the before-times, when you couldn't even reply directly to other people's comments in a thread. I have no idea what I was replying to, back then. In response to your theory: You are correct. If the surface they were on had less sway, it would take a lot longer to synchronize. If it had no sway, or an amount of sway so low as to be negligible, the metronomes would not ever synchronize.
No. The moving surface is what causes the synchronization. The base moves with the majority of the metronomes and the force of that movement is what throws the other out-of-sync ones into sync.
This is the same basic principle for weight-based Artificial Neural Networks. The average error is back-propogated to all individual metronomes and eventually the error in their tempos even out. It's quite amazing how applicable the concept of ANN's are with many real life phenomena.
So what you see is all moving together, while each metronome is neither pushing or pulling any more on the base, that oscillates in perfect timing offsetting the equal and opposite pendulums at the potential energy trough; the lowest possible expenditure of effort. I hope this explanation helps. See Sears and Zimansky or many other textbooks for the equations if you wish.
I would like to know: Within this set of metronomes, is there a metronome that kept its initial rhythm, around which all others eventually synched? Or are all metronomes eventually synching to a common rhythm, resulting from the entire set?
The shelf they are sitting on is allowed to sway slightly. If you look closely you can see it move. That's what allows the pendulums to 'feel' each other and sync up.
the surface itself is a sort of pendulum, with 32 pendulums on it. Newton's third law (equal and opposite reaction) means that the surface itself will start a sympathetic movement according to which way the aggregate momentum is flowing. From the first moment, one vector, either left or right, is 'more' correct from an aggregate POV. So any pendulum moving against the 'correct' aggregate will have to work harder than any pendulum moving with the aggregate flow and over time this finds a balance.
Yes, the motion of the base is the path kinetic energy takes between oscillators. It gently sways the pivot point of each oscillator, in rigid control of the base. Because the upper part of each pendulum is less massive than the lower part, the pendulum always wants to return to vertical. Each time it does it is given another kick from the wound spring inside, that release a bit more energy. The imbalance between the upper and lower pendulum is what exerts a net horizontal force onto the table.
meme-meme:This occurs because the table on which the metronomes are placed upon is moving in time with the average frequency of oscillation of the metronomes. As time passes, and the metronomes begin to slow due to dampening, the swaying of the surface, transfers its energy back to the metronomes (which is why they begin to sway with more force after a while) at a natural frequency equal to that of the sway of the table and the average frequency of oscillation of the metronomes prior to the sync
No. the motion of one ticking metronome can affect the motion of every metronome around it, while the motion of every other metronome affects the motion of our original metronome right back. All this inter-metranome "communication" is facilitated by the board, which serves as an energetic intermediary between all the metronomes that rest upon its surface. The metronomes in this video (which are really just pendulums, or, if you want to get really technical, oscillators) are said to be "coupled."
Yes it is amazing, the reason it works and the fact that it works is what makes it amazing, if you find no amazement in beauty in this, then you're the unamazing thing here...
That's exactly right, the platform is hanging from 4 strings attached to the wooden bar at the top, allowing each metronome to transfer it's energy into the platform.
Actually if you look more closely you will see that the table is swaying before they even start them swinging, by the end they all match the frequency that the table is swaying at... now thats some basic physics.

這個原理十分簡單:
所有的節拍器都放在同一張(會搖擺的)桌子上。
剛開始的時候，兩個人一個接一個啟動節拍器。
使用多大的力量，或是何時去啟動，其實都不會對最後結果有甚麼影響。
每個節拍器被啟動，就有各自獨立的節奏(節拍)，也就是所謂搖擺的振動頻率。
節拍器互相之間的搖擺頻率相接近的，就會尋找兩個頻率的中心點來做調整，桌子(重量夠大的)的搖擺搖擺頻率就會是這兩個節拍器認同的共振頻率。
如此依序每兩個節拍器互相找到一個共振的頻率，最後這兩個節拍器會以這共振頻率作為一同搖擺的頻率。也就是有相同的左右搖擺動作。
連搖擺的大小(振幅)也會相同。當這兩個節拍器有了共識，其他兩個有共識的節拍器再來跟這組節拍器做頻率的調整。
如此連續整合，最後所有的節拍器就會有相同的表現。
開始的時候，桌子並沒有明顯的左右搖晃。
當桌子的左右搖晃有明顯的感覺時，部分的節拍器已具有相同的搖擺模式。
桌子的搖擺與節拍器的動作越來越契合。
只要專注在那幾個不聽話的節拍器上，漸漸被其他整齊的節拍器歸化為一。
大桌子的搖擺頻率就是整體的慣性震盪頻率。
如果你放上更多的節拍器，不啟動他們。一陣子後，也會以相同的模式一起搖擺。

I'm guessing all the metronomes would have to be set to the same time period (height of the weight) for this to work… or would they?
Tomsonic41 yes they would. you can see the table they are on slowly start moving back a fourth, that's what helps synchronizes them.
I don't know why, but it is an oddly satisfying sound when they all get together.
if the table is not moving you can not see this effect, this a "trick"

You are correct. The table isn't swaying rhythmically at the beginning of the video. It is the combined motion of the metronomes that causes the swaying and helps get them all in sync.
The table doesn't help them. They only need the vibration of the table at any frequency to communicate with each other.
I believe that the table receives energy, and then suddenly it releases energy which synchronizes the ticks of those metronomes.

There is no special metronome among them. They are all affected by the same forces and some combination of their rhythms ends up as the result.

Metronomes, things that are used in music during your timing practice.

That's exactly right, the platform is hanging from 4 strings attached to the wooden bar at the top, allowing each metronome to transfer it's energy into the platform.
As time passes they get to the same frequency of the table.
Anyone else feels sleepy watching this (even after having a good night's sleep)?
so if you waited long enough, would they go out of synch again?
It's fascinating that the synchronization seems to occur back to front.
Was there any outside force applied to the platform the metronomes are on?
In a rigid table this would never be possible.
Actually, all the metronomes are getting in sync with the table.
