March 14 is Pi Day (alternately Archimedes' Constant Day or Ludolph's Constant Day, but who wants one of those in the face?). Snarky celebrated - and you can see the first umpteen digits in the background of today's comic. Pi Day is not officially a holiday, but celebrated by those who love the circle, nonetheless. Why? Because Pi is 3.14. Or slightly more. I suppose appropriately you'd celebrate it at 15:92, or 4:32 p.m. based on the next four digits.
To quote Wikipedia: "π is an irrational number, which means that its value cannot be expressed exactly as a fraction having integers in both the numerator and denominator (unlike 22/7). Consequently, its decimal representation never ends and never repeats. π is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can render its value; proving this fact was a significant mathematical achievement of the 19th century."
Pi Day Org has a nice list of the first million digits, how many do you know?
