Servers at the Hubbard Avenue Diner, our favorite local pie shop, wear clever T-shirts bearing the Greek letter pi π, which stands for the mathematical ratio of the circumference of a circle to its diameter: 3.1415926535, (et cetera, et cetera, et cetera). 
Remember learning about this number in geometry class, and competing to be the one who could memorize the most digits (now calculated by computer to surpass one trillion digits following the decimal-wow!)?
Today (3/14) is Pi Day. For fun and to honor this endlessly fascinating number, we offer here some interesting pi information. Absorb these facts while enjoying a slice of your favorite pie (Blueberry Crumble for me).

Enjoy your pi day. And please share with us your favorite pi fact and way to celebrate Pi Day.
