March 14, or 3.14, is a special day devoted to the unique numerical value of pi and for food lovers it's another excuse to eat "pie."

If you don't remember your geometry 3.14 in mathematical terms, also know as Pi, represents a constant— the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Did you know Pi was first calculated by Archimedes of Syracuse, one of the greatest mathematicians of the ancient world?  

And if you're not nerding out with other math aficionados around the world, chances are you're  drooling over pies you're going to honor the day with.
