Welcome to the 26th annual Pi Day, the mathematical holiday founded at the Exploratorium and celebrated by number lovers around the world. To honor the never-ending number 3.14159... (and Einstein’s birthday), we’ll serve up π-themed activities, rituals, antics, and plenty of pie. Find out what's so special about this famous mathematical constant, and take your (decimal) place in our annual march to the Pi Shrine!
