“Pi, Greek letter (π), is the symbol for the ratio of the circumference of a circle to its diameter. Pi Day is celebrated by math enthusiasts around the world on March 14th. Pi = 3.1415926535…” – www.piday.org

I guess this is why my son baked a pie (was actually a quiche) and took it to school. We were also going to celebrate by watching the movie “Pi” (one of my favorites) but we ran out of time. I’ve always liked the Pi symbol – so much so, I once carved it onto a rock.
