Basically, it suggests that if you drop enough needles (or matchsticks) of length

*l*on a wooden floor with planks of width

*2l*, you can take the ratio of total number of matchsticks dropped to the number of matchsticks that cross the crack. This ratio should eventually equal pi (3.14159265).

I thought I'd write a C2 program to simulate the proposition, and it worked pretty well.

EDIT: dropbox hyperlinks aren't working for some reason, so try copying and pasting these links.

Here's a demo.

Here's the capx.

If you let the calculation run for a little while, you should see the ratio value approach pi. For a variety of reasons it won't be perfect but it gets pretty darn close.

It's a very interesting proposition, and its solution goes into the depths of probability calculus.

So, there's your uncomfortable math truth for the day!
