Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (the 3rd month) since 3, 1, and 4 are the first three significant figures of π. It was founded in 1988 by Larry Shaw, an employee of the San Francisco, California science museum, the Exploratorium.
The link has plenty more to say and explain about the meaning of the day. I didn't realize that it's also Einstein's birthday! Or that some people celebrate Pi for the entire month of March. Just because there is no end to pi and the number goes on forever... I suppose it would be nice to have a pie that never ended.
It would be nice to find a reason to help yourself to a piece of pie, and today might give you that reason. I'm off to the store, and I do hope I am able to contain myself from buying a pie. I hope you have a good day, whatever you do! (Maybe just a tiny little piece...)
