Pi Day every March 14th.
That is, it was unofficial until now. After what I can only assume was an elephantesimal lobbying effort by Big Arithmetic, Congress has gone and officially designated today as Pi Day for 2009.
This non-binding resolution just shows how pervasive the reach of the global scientifico-numeric cabal is in our government and society. As if it's not bad enough that we already celebrate a holiday named for a number on July 4th, but now we have to celebrate a holiday for an irrational number on March 14th.
Shame on you, Congress!
