Pi (π) describes the ratio of the circumference of a circle to its diameter, a number that's awfully close to, but not quite 3.14. Since Pi is an irrational number, the digits of Pi never end and the pattern of numbers doesn't repeat. According to the Pi Day website, "With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal."
