Pi Day 2013
Brief History of Pi
Go to the Pi-Search Page and type your sequence in the search box at the top of the page. This web site will search the first 200 million digits of pi in a fraction of a second. (See “How it works” on the Pi-Search Page to find out how this is accomplished.) If it finds your sequence, it will tell you at what position in pi your sequence begins and will display your sequence along with surrounding digits.
No result? Try another sequence. The shorter the sequence, the better the odds of finding it.
What's going on?
It’s time to count. First, remove any toothpicks that missed the paper or poke out beyond the paper’s edge. Then count up the total number of remaining toothpicks. Also count the number of toothpicks that cross one of your lines.
Now use this formula to calculate an approximation of pi:
Pi = 2 × (total number of toothpicks) / (number of line-crossing toothpicks)

New Sport: Pi Ball ?
As recent as 2008, a new sport was invented in South Africa – supposedly on Pi Day. It’s played on a circular court around a central circular ball strike area – and it’s called “Pi Ball”.
It’s comparable to beach volleyball, but where two players on a team are separated by a net, pi-ball players instead stand diametrically opposite one another within the confines of a circular court.
