The set of pendulums act like discreet samples of a sinusoid which gradually increases in frequency. It starts to look more and more 'random' until the frequency reaches the Nyquist Frequency - the wavelength equals two samples. At that point, 'aliasing' occurs: the frequency appears to decrease and go through the exact same process in reverse, until it reaches 0 and all the pendulums are lined up again.
Not really random -- since the increase is gradual, you can see that the pendulums reach 90 deg. (0:42) and 120 deg. (0:46) phase when the pendulums look like they are divided into smaller parts (360/90) and (360/120)
Maybe I am not understing your point on aliasing, but it seems to me that in this case it's not that but just superposition of periodic signals with very similar individual frequencies that start in phase. Gradually, they start getting more and more out of phase, until finally most pairs are very desynqued (a pair can fall in sync again, but it doesnt matter since we want the whole system to be in phase again). This eventually happens and the process seems to repeat, albeit with less kinetic energy. Correct me if I'm wrong since this is very interesting, but I can't see the correlation with sampling here
I liked how: 1. It starts looking like a spiral right before it serpentines like a snake before desynchronizing again 2. How each of the above increase in duration with increasing period
@@Aidaryan2012 went back to sleep after making that last comment lol. And I am actually thinking of a romance between Wolves story lol. The female lead Camille deals with a loss of her younger sister after a Brutish forest fire but finding herself in a relationship with Prillian, the male lead, changes her life and helps her get over the loss since she's a lonely wolf. It's an abstract drama consisting of poetry and music the style of mideval and ancient styles.
The oscillations started at 0:26 and the same pattern is repeated at 1:28. This time interval between pendulums again coming in phase is equal to the LCM of the time periods of all the pendulums
Duration of an oscillation depend upon the length of the chord, through which the pendulum is suspended. We can see that the lengths of all the chords vary from one another, which is why it is creating this illusion.
I love how from that perspective you can see the different patterns emerge, stages of various familiar shapes found in nature and then once the wave had split perfectly, the stages of patterns reversed back to how they were initially started. Good ol' Physics :)
Wow! One of the rare moments that get me surprised and excited! I've seen really a lot but never came across this. Thank you for getting me fascinated.
That is an awesome piece of art! I would love to have one similar to this, maybe a bit larger scale. Amazing how just the difference in length of the hanging balls can create such a cool display by swinging at different speeds.

This video is exactly as described, it does not try to sway an opinions or garner a response that the person who posted it wanted it is basically what it say on the tin. Anyway I enjoyed it and was mesmerized by it, thank you for the post.
The pendulums have different periods because of their different lengths. Hence the phase relationships change continually throughout their motion. However, the time periods are commensurate (i.e. they have constant integral ratios). Hence the pattern repeats after a while.
1:08 Wtf. They can rotate left or rotate right depending on how your brain decides to see it. Focus on 1 side & you’ll see it rotate that way. It’s trippy
This is awesome. You can use the same principle to produce another cool optical illusion with LEDs set up in a single row. Just modulate the brightness of the LEDs (just like the amplitude of the pendulum) and put a semi-transparent acrylic panel over the strip of LEDs to diffuse the light a little bit. Ends up looking like a lava lamp but also can be timed to happen in a cycle. The math behind this is super simple AND fun! A really great way to learn about trigonometry. It would be cool if you guys would include the simplified mathematical formula to calculate the period of each individual pendulum with regard to string length. I'm not exactly sure what the math is in this situation (I'm not a math person really), but I think it's close to the below equation. And I'm talking about how to describe the oscillation of each individual pendulum. Then to get them to do cool synchronized patterns like the video you just have to adjust the ratio of the lengths of string. Sin(2pi * (time / rate) where the rate is controlled by the length of the string

Sin(2pi * (time / rate) where the rate is controlled by the length of the string
Maybe too late, but the period of an ideal pendulum is T= 2 Pi Sqrt(length/gravitational constant)
