New to this channel? It's all about teaching math visually. Take a look and see if there's anything you'd like to learn.
NY Times blog post about this problem:
wordplay.blogs.nytimes.com/20...
The original paper by Gregory Galperin:
www.maths.tcd.ie/~lebed/Galpe...
Evidently, Numberphile also described this problem (I had not known):
• Pi and Bouncing Balls ...
You'll notice that video has an added factor of 16 throughout, which is not here. That's because they're only counting the collisions between blocks (well, balls in their case), and they're only counting to the point where the big block starts moving the other way.

Another interesting observation : When the masses colliding are powers of some other base (say 3), the number of collisions still equal the digits of Pi, but in the same base. Eg : Pi in base 3 is 10.010211012222010211002111110221222220111201212121... If you run the simulation with masses of 1, 3^(2 * 1), 3^(2 * 2), 3^(2 * 3),..., then the number of collisions will be 1 (base 3), 10 (base 3), 100 (base 3), and 1001 (base 3) respectively. Number of collisions for 1,3^(2 * 50) will be first 50 digits of Pi in base 3 : 10010211012222010211002111110221222220111201212121 , or 2255343044159619899886237 in decimals.

This is why I love math. You always look at a problem, read it out loud, then discover something about that problem. It's like there is always a hidden puzzle in math equations. For example, in 7th grade, we were learning about circumference. My teacher showed the class a video which said that if you take the diameter and try to wrap it around a circle, there's a tiny bit left, to which I realized that that tiny bit looked EXACTLY like pi, or 3.14. It's so cool finding small details that make so much since!

I like how the speed of the last collision is an expression of the remaining digits. So when it's 314(15...) collisions it juuuust reaches the line, but when it's 31415(92...), it gives the moving block a proper final spank to send it on its way.

i don't know about a spherical cow, but there is popular joke about spherical horse: Some man hired physicists to calculate which horse will finish first in the upcoming races. They gave him their results. And that horse didn't win. Angry man asked physicists why is that so, and they replied, that they calculated race results for spherical absolutely black horses in vacuum. So this is a joke about over-idealized conditions that physicists use in their calculations.

It's from a Neil deGrasse Tyson's joke. It's about how physicists love to see the things in universe to be a perfect sphere.

But a physicist will answer that a perfect cow is a cow which is spherical.

Well at least you can see where the circle comes from coz the equation of a circle is (x-a) ^2 +(y-b) ^2 = r^2 so 1/2m1v^2 + 1/2m2v2^2 = const. is clearly a circle equation

The transient of any natural movement will be e^n where n is x*jw, which is a frequency. Then, any natural movement has “e” implied and a natural oscillation associated. We know from Euler that there is a relationship between e and Pi. Great video 👏

Question: Would this same algorithm compute TAU if we switched the walls once after the initial series of collisions before the larger block is ejected back out from where it came? Let PI be defined as C/r (circumference of circle divided by the radius), AND TAU which is C/d (circumference / diameter). Can we reverse the roles of the walls to block the heavier block from leaving, so that the "high impedance" wall and "open circuit" walls are switched?
