On March 14 every year, math geeks and number fiends alike celebrate Pi as one of math's most special constants. Did you know that "Black Swan" director Darren Aronofsky also made a movie about Pi? It's called "π" of course! Read on to get down on more facts about Pi and Pi Day!

  • Pi, Greek letter (π), is the symbol for the ratio of the circumference of a circle to its diameter. It represents the relationship between a circle’s diameter (its width) and its circumference (the distance around the circle).
  • Pi Day is celebrated by math enthusiasts around the world on March 14th. Pi = 3.1415926535…
  • With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal. Pi is an irrational and transcendental number meaning it will continue infinitely without repeating. See one million digits of Pi by clicking here.
  • Darren Aronofsky of critically-acclaimed “Black Swan” and “Requiem for a Dream,” made his directorial debut with “Pi”, a 1998 American psychological thriller film.
