Today is March 14, or 3/14; infamously known as Pi Day. Number aficionados across the country are chowing down on pie and discussing the importance of numbers as we speak. But did you also know it's Albert Einstein's birthday as well?! The theoretical physicist was born on March 14, 1879, in what was then the Kingdom of Wurttemberg in the German Empire.
As Andrea Peterson of The Washington Post states in her refresher course, pi is the ratio of a circle's circumference to its diameter. Most of us learned the abbreviated 3.14 number in grade school, but pi can actually be calculated our infinitely without a discernible repeating pattern. The number is both irrational and transcendental.
Einstein started working at the Institute for Advanced Study in Princeton, N.J. in 1933 and remained associated with the institution until his death in 1955. Princeton now celebrates Einstein as part of an elaborate "Pi Day weekend" featuring walking tours, pie judging, pie throwing, a pizza competition, and an Einstein lookalike contest, among many other activities.
