Pi in the Sky

Pi -- symbolized π -- is a mathematical concept. Take any perfect circle, measure the circle's diameter (the distance of a straight line through the middle of circle) and the circumference (the distance around the circle). Then divide the circumference by the diameter.

The answer you'll get -- roughly 3.14 -- is the answer you'll always get. Pi is an unchanging constant, true of every (perfect) circle regardless of the circle's size. Pi is also, interestingly enough, an infinite number: while we generally round off at 3.14, the actual number of pi is 3.14159265358979323 ... and so on.

March 14, being 3/14, is National Pi Day. So we've rounded up some resources about pi (the number) and pie (the rather tastier treat). Be sure to celebrate this day as you best see fit.

(We like key lime ourselves.)
