It's also Albert Einstein's birthday. I'd write about him and the theories of relativity (both general and special) but that's too much math in one day - trust me.

Today's the day. Go have some ROUND pizza. Or some ROUND cookies. Or some ROUND donuts (or some ROUND donut holes - but only the whole holes. Stay away from half-holes. They're nowhere, man.)3.

Cosine, secant, tangent, sine!
UPDATE: I didn't want this post to be political but alas there's a political angle to it. DemocraticLuntz at the dailykos has the story:
On Thursday, 10 Republican members of the U.S. House of Representatives voted against an official (but non-binding) resolution declaring today, March 14, 2009 (3/14/09) as Pi day.Here's the summary of the bill from thomas.loc.gov:
The House periodically passes meaningless non-binding resolutions that frankly have no point, but they usually pass unanimously, the like one the previous day about NASA.
Supports the designation of a Pi Day and its celebration around the world.The ten who voted NO were:
Recognizes the continuing importance of National Science Foundation math and science education programs.
Encourages schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.
