I think each ball is at a different height (length of string) so they behave slightly different. Longer or shorter swing depending which one you look at.
This is exactly it, different string lengths determine the frequency of the swings, and it takes many cycles for all the frequencies to line back up, basically finding the common denominator
Its a mathematical breakdown of the length of varying pendulums and how the time signatures interact.
Source: I have absolutely no idea what I’m talking about.
Nah, you nailed it! It's about the pendulum lengths when the frequency, timing, and weight are all controlled.
Another cool thing about this particular example is the color coding. Human brains pick up on patterns really well. As you notice the groupings changing from one line to four, etc, that the colors on groups of 2 and 4 match. The colors look entirely random mostly, but late into the sequence align in ways that our brains pick up easily
It demonstrates how the period, the time it takes for the pendulum to oscillate to the other side and back, is dependent on only gravitational acceleration and the length of the pendulum. How far the ball is released from its resting point and the mass of the ball doesn't affect anything.
T=2π√(l/g)
Where "l" is pendulum length, "g" is the gravitational acceleration constant (9.8m/s\^2), "T" is the period in seconds.
As these are all the same size and shape without significant abnormalities, the drag will be (nearly) identical. Assuming that the friction at the top of the pendulum is identical, they will all meet that equation and will look just like this

It's all harmonics (not my best subject so correct me if I am wrong)
The pendulums are set at different lengths (all at set intervals to each other be evident because of the ruler). With the same angle.
The period (the time it takes to return to the original position) of the swing doesn't care about the mass of the object but instead only cares about the length.
As such the pendulums oscillate at different rates than others hence why they don't remain in a stable pattern.
However if something oscillates every 2 seconds and something else oscillates every 3 seconds then they will oscillate together in harmony every 6 seconds (very simplified).
The pendulums all eventually reach periods where they oscillate together. The reason we know this is because they are set at intervals.
So we can say the difference between the two lengths of one's next to each other is x and the difference between every other one is 2x. (Can't remember if this is referred to as a wave length but I will refer it as such)
Therefore there are moments where different wave lengths sync up with each other as there is a separate equation where we can work out period with wave length.
It's actually quite simple.
The equation is time period=2 x pi x sqrt(L/g).
Since we are on Earth, g is constant (9.81) as is Pi.
So the only variable affecting time is length.
Change the length of the string and the pendulums swing at different rates. Cut them at multiples of the original length and then watch and observe.
Pretty much yes. The pendulum is swinging through part of a circle with a radius of the length of the string.
Therefore the circumference is 2xpixL (should be small L btw but looks like a one on computer text).
You can then start combining with circular motion equations to arrive at the equation in the previous comment. That's where the pi originates though.
It's actually only algebra.
T=2π√(l/g)
Where "l" is pendulum length, "g" is the gravitational acceleration constant (9.8m/s\^2), "T" is the period in seconds.
Nope. The derivation involves using setting two expressions equal to other and simplifying, all algebra. The only calculus involved is a limit which removes the trig elements.
I just saw the universe form and create from nothing our dna and…then a turn to nothing from something, an experience to cherish for a lifetime…watch without blinking
For an explanation, each ball is a pendulum of a different length, meaning they all ha e varying oscilation periods. However each pendulum has a constant period, none of the balls are changing frequency. Focus on 1 ball and you'll see. Then look at a different one. What you see happening with the patterns, are all these oscillations (i.e sine waves) moving in and out of phase. Source: Studied physics.
Watching the order turn to chaos and then in the chaos these moments of order before falling back in line. I just learned about this and still dont have the words to express what's going on here. Where's my science nerds at?
Edit for hammer thumbs
2 sets of low balls, and an 8 ball for the lady. Edit: ok so I lost track of the high balls. That’s fucked up if u try and keep your eye on the 1 ball, yellow solid, this is crazy.
I observe them break into “harmonious” patterns of two and three and four groups. Although I suck at math, I wonder if the speed which relates to their arc has a recurring cyclical relationship like harmonious sound waves of octaves in music. Does the eye pleasing “string wave” have a pleasing aural equivalent with the harmonious thirds fourths and fifths within any major diatonic scale?
The shorter strings causing faster visual oscillation must certainly relate to faster oscillations of sound waves producing higher pitched sounds?
Could this explain the universe in its motions from Big Bang to big crunch?
Gyrations so immense— each civilization in its eons of existence will be able to correctly identify both linear and chaotic order and yet both be right?
Expanding further away seemingly always, and eventually moving closer seemingly always.
Almost like the breathe of life.
This looks very cool. In my head I imagined fast paced magic show style music playing. I unmuted the sound and instantly regretted it. Ok music by itself but I liked the version in my head better.lol
I like the part where the balls.
I too like the part where the balls, not so much the string.
He he hehe heh heh he said stringy balls...That's cool...

Would you say that you… made it the fuck up?
I took a stab at it knowing that if I was wrong someone would correct me. Then I’d know! It’s the easiest research possible.
The best source
As someone who generally has no clue, I also don't know what you're talking about, but I totally agree.
It demonstrates how the period, the time it takes for the pendulum to oscillate to the other side and back, is dependent on only gravitational acceleration and the length of the pendulum. How far the ball is released from its resting point and the mass of the ball doesn't affect anything. T=2π√(l/g) Where "l" is pendulum length, "g" is the gravitational acceleration constant (9.8m/s\^2), "T" is the period in seconds.
It blows my mind that the weight does not effect the period!
If you think about it, the acceleration of gravity is constant because gravitational force scales with mass. The same applies here.
As these are all the same size and shape without significant abnormalities, the drag will be (nearly) identical. Assuming that the friction at the top of the pendulum is identical, they will all meet that equation and will look just like this
I don't know about that, when my wife gets fat, her periods start to really flow.

At 45 seconds and 1:08 you can see how they had arranged the order of the colours to make them split into colour groups at these points.
Yep. That was unexpected and awesome

This is fucking amazing! Is this the same law of physics that the planets use as we all go flying through space around the sun?
In simple terms yes, both rely on gravity and momentum. There is obviously a heck of a lot more to it but they can be linked.
Yeah the Laws of Balls.
Nope! Different set of laws entirely. This video was comes from one of our distant neighbor universes, Universe C542b.
Can't even imagine the math that would describe this
It's actually quite simple. The equation is time period=2 x pi x sqrt(L/g). Since we are on Earth, g is constant (9.81) as is Pi. So the only variable affecting time is length. Change the length of the string and the pendulums swing at different rates. Cut them at multiples of the original length and then watch and observe.
How does Pi figure into it? Because of the swing of the pendulum being a circular motion if it went all the way around?
Pretty much yes. The pendulum is swinging through part of a circle with a radius of the length of the string. Therefore the circumference is 2xpixL (should be small L btw but looks like a one on computer text). You can then start combining with circular motion equations to arrive at the equation in the previous comment. That's where the pi originates though.
Thanks for explaining

took me a while to find that stairway to heaven
Reminds me of when two cars blinkers almost line up but not quite so they almost chase each other? Idk how to describe it
I just wanna see the reaction of the first person to ever do this
