Happy Pi Day!

Geeks! Where you at? It's time to celebrate the ratio of the circumference of a circle to its diameter, yo.

For those of you that are unaware March 14th is Pi Day. (3.14 . . . celebrated on 3/14, get it?) It's not much, but we math teachers have to have something to celebrate with our students. Besides, pi is the world's most famous irrational number and one of the most useful. Why else would people dedicate so much effort to memorizing its digits?

I personally only know 3.14159265358979 . . . . That's because of the mnemonic device, "I need a drink, alcoholic of course, after the heavy lectures involving quantum mechanics." The number of letters in each word corresponds to the digits after the decimal point. Now, before you start looking down your nose at me, Chao Lu of China recited the first 67,890 digits of pi on November 20, 2005. He hold the world record for pi recitation. (Collecting Transformers toys doesn't sound so weird now, does it?)

I'll leave you with a palindrome, "I prefer pi."
