“I think the most important question facing humanity is, ‘Is the universe a friendly place?’ This is the first and most basic question all people must answer for themselves.” ~ Albert Einstein

Today is March 14, which corresponds to the first three digits of Pi. Because pi is 3.14159….some schools hold their celebrations until 1:59.
Pi is called an irrational number; it has an infinite number of digits: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679…First 100 digits of Pi
Pi is the ratio of any circle’s circumference to its diameter. In other words Pi is the number you get when you divide the circumference of a circle (the distance around the circle) by its diameter (the distance across). It is typically written as 3.14.
March 14th also happens to be the birth date of Albert Einstein—which makes it a double math celebration. You can watch NOVA‘s “Einstein Revealed,” which exposes the hidden life of Albert Einstein and traces the birth of his groundbreaking ideas. See it at: http://to.pbs.org/15OBsMm
