HAPPY PI DAY: March 14th (3.14) is PI day and all around the world mathematicians are celebrating this compelling and mysterious constant of Nature. Pi appears in equations describing the orbits of planets, the colors of auroras, the structure of DNA. It's everywhere.

Humans have been struggling to calculate  for thousands of years. Divide the circumference of a circle by its diameter; the ratio is . Sounds simple, but the devil is in the digits. While the value of  is finite (a smidgen more than 3), the decimal number is infinitely long:

I have a metal colander connected to my ground system and plan to wear it on my head the day after PI day.  One never knows what one is supposed to "beware" of on the Ides of March ....

Pi is a fascinating number, and has gendered several very interesting books.   "A History of PI" is absolutely fascinating.  My wife thinks I'm a nut case for reading that sort of stuff ...  Roll Eyes
