Today marks the celebration of the mathematical constant, Pi, which is used to calculate the circumference of a circle.
The Maryland Science Center celebrated everything Pi, from eating pie to reciting pi, to exposing the secrets of Pi. Dangerously Delicious Pies even donated pies for a party there. Pi(e) Day gets even sweeter because it’s also Albert Einstein’s birthday, who would be 133 years old today.
How will you celebrate pi?
