In honor of our favorite irrational number, and in lieu of hot chicks, I give you National Pi Day (3/14...get it?! D'oh). Anyway, some fun facts about Pi:
1. Congress has devoted a day to it...to the chagrin of some.
2. According to the "History of Mathematics" it is a constant "whose value is the R of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.14159 in the usual decimal notation." In other words, you need it for any sort of meaningful mathematics.
3. Pi may not be a natural number, that is, any meaningful block of digits may not repeat more or less so than would be expected through random numerical assignment
4. People loooooove to calculate pi, and, in this age of supercomputing, Pi has been expressed or carried out to the 1,241,100,000,000th decimal point without a repeating series.
5. For all of you SETI folks (like me) out there, yes, they did write code for calculating pi on your home computer. Try here.

*Besides being Pi day, on this date in 1879 a droll little man who liked to tinker with formulas was born in Ulm, Germany....
