Each year on March 14, math aficionados around the world celebrate the mathematical constant known as pi, which is represented by the Greek letter "pi." Pi relates to the ratio of the circumference of a circle to its diameter, which comes to approximately 3.14159, but goes on infinitely. The celebration date is significant because it corresponds to the first three digits of pi, or 3.14.

While discussions about math and ponderings on pi in particular can fill the day, this calendar event also marks the opportunity to dig into pi's homonym ... pie. Calculating circumferences and diameters may be even more intriguing when using an actual pie. Any pie can fit the bill – but in honor of St. Patrick’s Day, why not serve a Chocolate Mint Mousse Pie! Irish eyes will be smiling!
