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.

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!

@siddharthabbanerjee 2 года назад

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.

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.

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

This is amazing, physics teachers never taught this, and everything we learned was designed to solve problems, from conservation of momentum to conservation of mechanical energy, and we even came to a conclusion E（lose）=1/2 (M1•M2)/(M1+M2) • V（relative） how fascinating physics is now

@juliangoulette7600 4 года назад

Perhaps you could set up analogous situations for any other base: 0. You have two blocks with masses of 1 and b^2^(d-1), where b is the base of the number system and d is the number of digits in that base you want to compute. 1. Count the number of collisions in that base. 2. You now have an approximation of pi*b^(d-1) in that base.
