March 14, 2013 — Thursday March 14 (3.14) is National Pi Day around the world and any way you slice it, it's good geeky fun.
Unfortunately National "Pi" Day has nothing to do with food.
It's an actual day to celebrate a numerical ratio.
True mathletes around the world celebrate Pi Day every year on March 14. That's 3.14, as in the first few digits of Pi.
Pi 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.
There are many ways of observing Pi Day, which include eating pie, discussing the significance of the number and more recently watching the Oscar winning Life Of Pi.
The earliest known official Pi Day celebration was organized by Larry Shaw in 1988. The celebration was held at the San Francisco Exploratorium where Shaw worked as a physicist.

Happy Pi Day (3.14) Domino Spiral
Uploaded on Mar 13, 2011
Or Half Tau Day...to mark the day, I've made my biggest spiral yet...and using a formula with Pi, I estimated the total dominos in this spiral to be 10178.75 dominos. I counted the dominos and the estimate was close. 10,059 dominos were actually used. Can you spot the 2 hidden references to 3.14?
