The magic number

At Google, they're getting ready to celebrate Pi Day, which culminates tomorrow, March 14 at 1:59pm, a date and time that correspond to the first six digits of pi: 3.14159. (Some people celebrate at 1:59am.) Of course, since pi is a member of a select group of irrational numbers, meaning they can't be expressed as a fraction, there are an infinite number of digits in pi. You can even set a world record for reciting pi from memory if you have the spare brain cells to remember 100,000 or so digits. Odds are, you certainly won't remember the one trillion digits past the decimal point that computers have calculated.
