Fun fact: If you change “rainbow” to “to”, “are” to “you”, “haha” to “never”, “pretty” to “going”, “dancing” to “up”, and “are” to “give”, the sentence becomes a lot different.
Hey Daniel, thank you for making and uploading this video. Just to helpfully correct the spelling in first paragraph of the video description: "This simulation was made using 40 pendula, each having frequency between 25 and 35 cycles per minute. The top right graphic shows the phase of each pendula and the top down shows the phase difference with the slowest pendulum.". Many thanks :).
I wish we could have pendulum lights for Christmas rather than blinking lights, which hurt my brain & give me fits. But these I could watch all day! (I know the blinking lights use less power & I'm all for that. but can't help the migraines they give me.)
Actually, mathematics does a pretty good job of explaining this! For instance, let's say you have two pendulums, one goes back and forth in 3 seconds, one goes back in forth in 4 seconds. We know that those two pendulums will appear to synchronize every 12 seconds, since 12 is the least common multiple of 3 and 4. What's going on in the video is just like that, but it's much more complicated since there are more pendulums that are all going at slightly different rates.

I really like that you added a periodic position diagram and a phase shift diagram as well
haha pretty rainbow colours are dancing

Man, the MCU Phase 7 Infinity Gauntlet is looking great!
Thank you, Daniel Koga 🕊 your creation is lovely & I learned a lot
Ha! Bensound! I use this for hold music!!
Why do I feel like this is gonna blow up... Anyway, that was beautiful!

Excuse me sir.
What program do you use
How did you make it?
Matlab. The code is in description.
from vpython import *

chords[i].axis = bobs[i].pos - support.pos

rainbow!! Yhaa!
Just watched this while listening to Giorgio By Moroder - Daft Punk, [e x 10]/10
So beautiful ❤️❤️❤️
sou sua fã!!
Now make them double pendulums
im losing it man
I wish we could have pendulum lights for Christmas rather than blinking lights, which hurt my brain & give me fits. But these I could watch all day! (I know the blinking lights use less power & I'm all for that. but can't help the migraines they give me.)

Somethings we cant fully explain, except, "its God's work and its natural, we are just there to reveal what already has been created"

Yeah... It's just GCM...

really very good funny game
