So tempted to spam this thread with as many digits of pi possible...

Try memorising the digits of pi.

It's actually really fun and it's a nice little brain exercise.

Use this song to start you off with the first 150 or so digits.

Enough to entertain myself for a good few minutes when I'm bored =)

An interesting fact:

The following series is also known as the Leibniz Series or Leibniz Formula:



The series is also very closely related to a problem called Gauss' Circle problem, where we want to count the number of integer co-ordinates (called 'lattice points') that lie inside or on the circle centred at the origin and with radius r.

Unfortunately, this series converges very slowly to pi, so it is not the most efficient way of computing the digits.

Pi shows its face in even the most unexpected of problems seemingly totally related to pi.

For example, suppose I have a stick of some unit length.

In front of me, I have horizontal intervals (imagine floorboards) of the same unit length.

When I throw the stick, it can either cross one of the intervals or lie in between two intervals.

The probability of it CROSSING a line is.... you guessed it!



So just by throwing sticks, I can approximate pi!

This is more commonly known as Buffon's Needle Problem.
