A slice of Pi, please?

Pipie1_300dpi If you tell people that it's Pi Day, they might, understandably, think apple or banana cream. Maybe pumpkin. Mmm. I could go on and on.

But not so fast.

March 14 (Get it? 3-14, as in 3.14) is Pi Day -- not -- sorry -- Pie Day. In fact, it's the 20th annual Pi Day. And no, schools are not closed.

The Greek letter is the symbol for the ratio of the circumference of a circle to its diameter, known to all high school math students as well as geeks everywhere: 3.1415926535 and on and on.

The first Pi Day was held in San Francisco, at the Exploratorium. Larry Shaw, a physicist and Pi Day creator, pictured below, says people on Friday will walk around the Pi shrine approximately 3.14 times, and, among other things, eat pie.

In a cosmically correct note, Friday is also Einstein's birthday. Let us know how you will be celebrating Pi Day.

I'll be wearing my Pi Day tshirt, drinking from my key lime pi mug, while I wait for the Giant Pi to drop at MathematiciansPictures.com and watching the World Federation of Pi Pi Day video while I wait. I also might go to the Pi-O-Matic at the Pi Diner and get some Pi - maybe a light meal of a million digits or so. Pi Day perfection.

For those folks who can't get to the Exploratorium for the annual PI Day celebration--such as singing PI songs,creating a Rube Goldberg-like PI chain reaction, eating pie, throwing cream pies in 3 staffers' faces while a physicist talks about PI in the trajectory--they can visit the Exploratorium and its alter ego 'Splo in Second Life. Check out PI Day activities and PI Day art--e.g., the PI-eta, the Leaning Tower of Pi-za. Among the visitors coming to the Exploratorium on PI Day will be a Google Dad, his artist wife and their infant son, PI.

I think it's great what Shaw & those at the Exploratorium have done to bring about awareness for Pi & math. It's great that thousands of people hear about Pi, and learn about circles and other math concepts at least once a year. And, associating that with a slice of apple or rhubarb pie is... yummy.

I always loved Pi day -- until I found out it was math! Guh.

If we are to be artithmetically correct, in the interest of precision,shouldn't the celebration be held at about 3:35 am or so, which would be exactly 3.1416?

Man, I've been running around in circles all day.

You have to eat a square piece of pie at 1:59 PM. Pie are squared!!!
