Today is March 14, and that means it's time to celebrate pi! Pi is defined by Wikipedia as "either as the ratio of a circle's circumference to its diameter, or as the ratio of a circle's area to the area of a square whose side is the radius." Wow, that's a big definition! But we probably all remember it as the value that helps us get the circumference or the area of a circle. Since almost everything in our world contains circles, pi may be the most important, and famous, symbol in the world. Pi day also happens to be the birthday of Albert Einstein, the great physicist.
