Pi Day 2012

It's Pi day - the day on which we celebrate both the Greek letter π (pronounced "pi"), which denotes the ratio of a circle's circumference to its diameter, as well as the delicious round treat. The number π, to two decimal places, is 3.14, hence the connection to March 14 (3-14).

I can think of no more appropriate way to celebrate than with the song "Pi" by the Alferd Packer Memorial String Band:





The band was my favorite free entertainment at the Kansas State Fair last year. Here, luthior (maker of stringed instruments) Steve Mason (left) shows Ace the Kansas-shaped end of his guitar. That's Jim Brothers at right. (more pictures: 1, 2, 3, 4, 5)
