National Pi Day......March 14th 2013

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.
Great tips to celebrate math on Pi Day.
  1. Prove Pi exists by measuring the circumference and diameter of circular objects around the classroom or house and solving for the equation: circumference = (pi) x (diameter).
  2. See how many digits of the number Pi you can recite. A Japanese man in 2005 memorized pi to 83,431 digits.
  3. Write a Pi-ku, a math version of the traditional 5-7-5 syllabic haiku. A Pi-ku of course, follows a 3-1-4 syllabic pattern.
  4. For example:
    Math is fun
    Mixed with some pie
  5. Bake a Pi-themed pie. Whether savory or sweet, eating deliciously circular pies is a highlight of every Pi day.
  6. Impress your friends by learning the song, “Mathematical Pi,” set to the tune of “American Pie”; or sing Pi Day carols.
