March 14th is Pi Day
As you probably know from math class, “π (sometimes written pi) is a mathematical constant that is the ratio of any Euclidean circle’s circumference to its diameter. π is approximately equal to 3.14. Many formulae in mathematics, science, and engineering involve π, which makes it one of the most important mathematical constants.” Pi is such a fascinating number that it has its own holiday. Pi Day is celebrated on March 14th, which also happens to be the birthday of Nobel Prize-winning physicist, Albert Einstein (March 14, 1879).
