March 14th is Pi Day

Yes you read it right, there's a celebration on March 14, known as Pi Day...no, not the kind of pie you eat, but the kind of Pi that is a mathematical constant. Nerds use it, bees use it, even birds up in the trees....no, no that's not right! Let's begin again...have you heard the old saying, "Pi are squared," and you always wanted to say, "No, pie are round?" Well, join the club, because that's the way I always looked at it too. Mathematics, as anyone who knows me can tell you, is not my strong suit. But the mathematical formula for squaring a number can be repeated ad infinitum and is a very important thing to scientists, physicists, engineers and well...nerds. I promise this is not going to be a mathematics lesson, because there's no way I would understand it enough to explain it. Let's just say it's a fun holiday and celebration for lots of wonderful people we know, and I've put together some things they might like in the spaces below.

Pi Day was created in 1988 by physicist Larry Shaw at the San Francisco Exploratorium. Congress made it official on March 11, 2009 and it has now become an international celebration. Pi Day is always on March 14, because those are the three numbers (314) most important to this mathematical constant. The day was created to focus more attention on the study of mathematics.
