# Einstein’s birthday and Pi Day

Today is Einstein’s birthday, as well as Pi Day.

Albert Einstein’s birthday as well as Pi Day is March 14.  Einstein, born in 1879, was the celebrated mind that gave us the theory of relativity and Emc2.

The mathematical constant π or pi expresses the ratio of any Euclidean circle’s circumference to its diameter.  Its decimal representation never ends and never repeats (though it is commonly abbreviated to 3.14).

Princeton has celebrated the 14th with pie and an Einstein look-alike contest.

1. And it may be a good day to contemplate the perhaps significant contribution made to Einstein’s work by his first wife, Mileva Marić : http://en.wikipedia.org/wiki/Mileva_Maric … spread the word. 🙂
