Saturday, 3.14, is pi day. Pi (π) is the symbol for the ratio of the circumference of a circle to its diameter (3.14159265358979...). Math enthusiasts and other geeks celebrate Pi Day around the world. Some schools hold contests for memorizing the most digits of pi. In San Francisco people gather at the Exploratorium for the pi parade where everyone marches to and around the Pi Shrine (a small brass plate engraved with pi to a hundred digits) approximately 3.14 times holding one of the digits of pi. Afterwards they eat pie. If you are looking for a fun book about pi, I recommend Sir Cumference and the Dragon of Pi (A Math Adventure). If you just want to celebrate shapes, my kids loved Shapes in Transportation. And if you haven't had enough math and science celebrations, it's also the 130th birthday of Albert Einstein (14 March 1879).
