This is a good idea to get people’s interest by showing the problem in a short. These videos are awesome and much more ppl should see them. But I think it would be better if you schedule the shorts with some delay and don’t post a bunch in a row to the same time, then release a bunch of videos, then a bunch of shorts, … In my opinion releasing one video per week at max and then the corresponding short, then the next video, … would be better. But other than that I really like your explanations.

The frequency of collision can be expressed as just that and frequencies are tied to waves while waves are tied to circles
@@tone618That's not actually it-we don't care about a frequency, we care about the total number of collisions. There's no wave mechanics in the proof, just conservation of energy and momentum.
@@jyrinx notice how the speed of collisions increases as both blocks approach the origin? That increase in speed creates a tone with a frequency. As the mass of the largest block increases that tone both increases in pitch and becomes a smoother approximate of some sin or cos function. Simultaneously as the mass of the block increases the resulting number of collisions better and better approximates pi. There absolutely is a wave function here.
Pi has an uncanny habit of showing up just about everywhere.

I just realized, if you track the motion of the cube it moves in a circular arc and the mesurment "collisions" is actually the rate at which the speed the big mass changes , similar to acceleration.
Although ideally it should look more like a flattened parabola
That adds up

It's actually not a circle but more of a measurement of the rate of change in the motion of the bigger block. The bigger the block, the more data points there are in the arc that follows the curve that would be considered the top of the circle.

Another perspective!
If left block has infinitely small mass, then it acts as an ideal gas particle, which upon compression gives higher and higher pressure, thus acting like a spring. And any sort of oscillator is connected with a trigonometry, since both 1d oscillation and 2d circular orbit path stem from the attractive force directed towards some point. So it's no surprising we've found "pi" here, since these two things are deeply interconnected.
That's deep
whoaOhhhhhhhhhhhh
That feeling when a logic path becomes illuminated. Like a proof ,or a design.
And now it seems so obvious 😄
That's awesome
🤔 would it have to be a point mass particle ? Seems like the current block already has an increasing rate of collisions that ≅ oscillation....🤷♂️
And there must be some formula that Relates the collision oscillation to a circle ......
Ooooo, look, as the oscillation rate is affected by the bigger block's mass, when that bass goes up by a power of 100 , the number of collisions increases by pi x that exponent
Given x is the value of cube times the sum being square the coefficient balance can equate to being rectangular along the y axis of a frictionless plane in theory not being circular. Thus collision predicts reckless behavior and the allegory of all sides being even, further reinstates cube. Even so quantumly objectifying the odds of pi from the theory of bounce we’ve conducted “slide”into cubical melee resulting mathematical violence and that’s all possible theoretically to Schrodinger‘s cat who’s was a gold fish Perhaps.
Idk why but those rapid bounces are so satisfying to hear
The pitches the collisions make are interesting too

(It is specified in full video)
Pi is like the dark souls bonfire of videogame easter eggs, it's everywhere
If I had to guess, this is replicating a horizontal wave, which is basically a type of oscillation and pi shows up a lot in oscillation / waves. I don’t remember all the pieces of the puzzle but it is related to this
I could picture that. Anything moving side to side is (also?) moving up or down if you change your perspective and once you try to map that point out and you find your findings. So once you have your results you can be like be “hm. oh yea, math”
Im not a mathematician or anything but if you mapped the frequency of collisions on a graph by putting quantity on the y axis and time (or something) on the x axis, as the heavier block collides with the lighter block closer and closer to the wall and then further and further away, wouldnt the graph be a single symmetrical wave? Im assuming thats where pi factors in
@99jaa You're right. You aren't a mathematician ❤
@@samuel_colson explain it then instead of trying to be funny
@@99jaa Yea I think you're close. If we construct the formula for momentum of the two masses and assume conservation of momentum in the horizontal plane, we get a cosine formula. But I'd need to do a bit of math to find the formula for the number of collisions. It would probably be some multiple of Pi.
