Today is PI day, March 14th (3/14). On PI day, there are a few things people often do to celebrate:

• Eat pie
• Da pai (play cards)
• Watch the movie Pi
• Recite digits of ? from memory
• Sing “Oh, number Pi
  Oh, number Pi
  Your digits are unending,
  Oh, number Pi
  Oh, number Pi
  No pattern are you sending.
  You’re three point one four one five nine,
  And even more if we had time,
  Oh, number Pi
  Oh, number Pi
  For circle lengths unbending. “

pi is approximately 3.1415926535897932384 62643383279502884197 1693993751058209749445923 0781640628620899862803482 53421170679821480865132823 0664709384460955058223172 53594081284811174502841027 0193852110555964462 294895493038196, and is related to the area of a circle by the equation A= ? * r².

   Did you see the story on the Today Show about the kid who was able to recite all of the numbers in Pi on air? Call me crazy, but if you’ve got enough time to sit there and memorize all of the numbers that make up Pi, you should probably get out more.
