Simulating a two-body collision problem to find digits of Pi
I came across a nice video on 3Blue1Brown's channel that highlights a very indirect way to find the digits in Pi. I'd suggest watching the whole video, but briefly:
The setup is as above. A "small" ...

"Do I understand the gravity of the situation?"
What is this?
This is a two-dimensional physics simulator that models gravity and collisions between circular objects (though it doesn't model rotation).
How do you use it?
You can tweak the following ...
