After all the excitement of Pi Day (3/14), I'm not sure a nerd like me can survive. Next to the upcoming glory of Avogadro's Day (6/02), nothing else is so exciting. For the non-nerds out there, Pi is a constant fundamental to Euclidean geometry, Avogadro's number is a constant fundamental to chemistry as we know it. Together, they define what kind of universe we are experiencing.
On a more serious note, please keep the people of Japan in your thoughts. They are in the midst of a once in a lifetime disaster. (And beware the spammers and scammers if you donate to the relief efforts.)
