Happy PI Day

As if they don't have anything better to do in this time of crises, this week US Congress passed a resolution recognizing March 14 as "National PI Day". It is a day to celebrate the mathematical constant pi (how do you type the Greek letter?). PI Day is observed on this date (3/14) due to pi being equal to 3.14 ! The first celebration was held at the San Francisco Exploratorium in 1988. So everybody, Happy PI day!!!
