Tomorrow is Pi Day

Tomorrow is Pi day - WL was kind enough to email this notice (redacted):

π (Pi) day will be celebrated on March 14th.

A variety of pies will be available about 1:30 in the kitchen Wednesday.

True π fanatics should celebrate precisely at 1:59:26 (3.14 1 59 26)
(however, that would make some folks late for the 2PM meeting).

and

The mathematical constant π is an irrational real number, approximately equal to 3.1415926, which is the ratio of a circle's circumference to its diameter in Euclidean geometry, and has many uses in mathematics, physics, and engineering. Tastes good too…..

He's not the only one excited to be celebrating Pi day - there's a website devoted to it, and Wikipedia even mentions various "pi approximation" days.
