Happy Pi Day! 3.14

Today, we celebrate that most famous of irrational numbers: pi. For those of you that forgot your middle school math, pi (approximately 3.14) is a special number used to find the perimeter (distance around) a circle. The formula is pi times the diameter. So if you have a circular jacuzzi that is 8 feet across, the distance around it would be approximately 3.14 x 8 or 25.12 feet.

By the way, pi is called "irrational" because the digits of pi go on forever without repeating themselves. According to one website, in 2002, a team of people calculated pi to 1.2411 trillion digits!

Anyway, I hope your Pi Day was as exciting as mine.

UPDATE:

Here's a cool website that lets you estimate the value of pi by throwing needles on a table.

Brian, somehow it seems you would be more likely to celebrate "Happy PIE Day"!!!! (Nothing irrational about that!)
