Today is Pi Day! What I mean is Pi the number not Pie the food. Pi is the ratio of the a circle’s circumference to its diameter. The day is selected based on the value of pi after 2 decimal places which is 3.14.

Why I celebrate it when it is just for the geeks? Duh, I am one of them.

Did you know that according to the novel Contact by Carl Sagan, there is a hidden message in pi on base 11?

Don’t forget to eat your pie today!
