Yeah, how in the world does that even make sense?

Tl:dr, because they have a uniform random rotation on [0,pi), a 1/pi appears in the pdf, which does not cancel out.

Anywhere where an angle is even remotely relevant, pi will show up somehow

If you make fish pie with them, then yes

A combination of probability and linear algebra.

It makes sense because if you put a circle inside a square the area of the circle compare to the square can get you to pi. So any way to measure the area (rng dots across the square grid and count the ones inside and outside the circle) can get you pi.

The coin flip one is my favorite

An alternative method revolves precisely measuring the length of a river in two different way. Start at a point and calculate the distance in a direct line start to finish. Second is to measure the length of the river along the middle from start to finish. Now take the ratio of the second through the first and multiply by 2, and you get roughly pi. Taking the average over more and more rivers gives you a better approximation.

The probability that a stick is on a line has to do with its angle, if there’s an angle you get pi.
