Happy Pi Day!

"PIEDMONT, CALIF., March 10, 2015 (GLOBE NEWSWIRE) -- Pi Day is coming on March 14! And not just any old Pi Day, but an "Epic Pi Day" on 3.14.15 at 9:26:53; that date/time corresponds to the first 10 digits of pi (π = 3.141592653). This happens only once per century – truly a "once-in-a-lifetime event" for most people.

 Why pi? Beloved worldwide, pi is simply the never-ending number π = 3.14... with no repeating patterns. Being irrational, it cannot be represented as the quotient of two integers. It is used to calculate the circumference of a circle – any circle – from its diameter, among a multitude of other applications in math, physics, and engineering. Pi appears "behind the scenes" in almost countless ways across many disciplines."
