Thanks for joining us for Pi Day in 2022!

National Pi Day, also known as March 14th,  is when math lovers around the world celebrate Pi, the ratio of a circle’s circumference to its diameter. Often approximated to 3.14, Pi is a number that appears everywhere in our daily life.  It's used in calculations for building and construction,  communications, music theory, medical procedures, air travel, and space flight, to name a few. It's encoded into everything from a zebra's stripes to a leopard's spots.
