Did Someone Say Pi?

Here's a link to read about the man who first used the Greek letter π  for the ratio of a circle's circumference to its diameter.  The Man who Made Pi

(just so you know, in the interest of full disclosure, I looked up what Pi is. I knew it's usually written as 3.14, but had no recollection from school days as to what it means; I am thinking I am not the only one.)

Not This Pye

Anyway, this year's Pi day is unique, and won't happen again for 100 years. March 14, 2015.

So I think it is worth noting.  And possibly baking a pie as well. After all, a pie is a circle, so you could go ahead and calculate the Pi of pie before eating it. Yummm!
