Pi Day

It is 3.14 and today is Pi Day.  Wikipedia tells me that people started celebrating this day only since 1989. That seems too late to me, given that we know about this mathematical constant for at least few thousand years now! It is hard to know when and where exactly this number first appeared in our ancient history. Apart from Egypt and Babylonia, this constant also appeared in the ancient Indian texts. In particular, the Vedic text śatapatha brāhmana (roughly means exegesis of a Hundred Paths) quotes this number to be around 3.139, which is very close to the real value. A thoroughly referenced article is here.

For now I can think of the best way to celebrate this day: Eat a delicious pie while watching the movie Pi.
