This experiment from the Harvard Natural Sciences Lecture Demonstrations is mesmerizing to watch.

That is a fascinating display .

The Universe seems to be driven by patterns , - or is it our brain producing the pattern ?

Whichever way it is , its a heap of a lot of fun . Never a dull moment !

Hi !
Pendulum waves experiment is something more than the a well-known"classic" lab-demo : "Newton's cradle".

Maybe we can think "deeper" (or simpler...) about our topic with the help of the suggested display:gravity power as waves,a pendulum arrangement (equivalent) as a device...

All the best! / Alex

Thanks for posting this Scott

It is great for meditation when we come up against inventors block. The natural reaction helps understanding and amazement.

Are they really uncoupled?

Great find, Science thinks pendulums like this are neat, fascinating and beautiful but have no hidden secrets that they can't see, they have pendulums all figured out, hilarious.

now that's visual harmonics.

Very interesting to watch but don't get too mesmerized by it; it's all a matter of timing. Like music. You should see what happenes when you take two systems traveling at different rates but have them loosely coupled together ( like magnets on two same sized wheels but at dirrerent at rates of speed ) Each affects the others rate of motion. The fastest one ends up slowing down and the slower one ends up becoming the faster. Then it alternates again. But they pull on each other in surges throughout all of it. A very pretty harmonic dance.
Back to the pendulums, something key to note is that although is it fascinating and educating to see that across the whole period of time there are periods of both chaos and uniformity, each sits at an energetic level. An octave so to speak. When the pendulums are going through what looks like serpentine motion this uniformity wont all of a sudden increase the energy level across the whole.

Agreed,

I was kinda knitpicking, i hate it when the obvious seems to be missed or neglected. I do not think "odd sympathy" from my boy Huygnes effects the outcome of the display in this case.

All out of whity things to say, sorry

Have you been researching pendulums as of late Scott?

Somehow I think this vid dovetails rather nicely with the idea of completely natural but quite unexpected results that can really only be attributed to the specific design or configuration of the objects being affected by gravity.

This of course raises the issue of "optimizing" gravity's effect on an object by modifying and adapting its shape and weight quite specifically towards that end.

Obviously the math and geometry have more than just a little to do with how far the effect can be extended.

This one is also just as intesting to listen to for the amount and pitch of the sound that's also being just as energetically generated and released along with the motion.

Convex mirror ? The deco anound the edge, wonder if that's purely aesthetic or purposely designed to reduce contact area/induce specific behavior ?

[murilo]

This is a beautiful stuff to see.

These pendulums was built in crescent scale and with double chord to avoid side swinging.

Every pendulum obey to the law who says that the velocity will be the same for a same length - or same radian velocity for each size - sorry... roughly...

Every one will find its length velocity decaying according 'g' laws...

The guy left all pendulums at same time, forcing all smaller to follow the first and longer one, for that very first instant.

All them 'tried' to reach and find to their 'proper velocity', each one by itself, according each length.

May appear, but this was not a chaos and would not be possible if they have had same length.

Funny as they met again the very first rhythm for a while, before restart the dance all together.
Best!

We can see a common fulcrum/support and a lot of big size pendulums moving at the same rate and exactly together (synchronized).

A natural question about this amazing interplay of pendulum is referring to their size...so,we can imagine and test many othars arrangements (pendular mechanics...)!

.....this time a single ( "all together") syncro wave with 32 metronomes (counterweighted pendulums),at :

www.youtube.com/watch?v=kqFc4wriBvE

Without concern , regarding the size (small...big) or the shape (common....counterweighted ) of pendulums ,we have a certitude and a proof:a "self",that of syncro motion/swinging (with a starting push),if we have a common "stabile substrate".

But with a "mobile substrate/fulcrum/support" ?

There is something "strange",but wonderful around us?

All the best! / Alex
