The value of Pi rounded to four decimal places is 3.1416, which makes today (3/14/16) one of the most prominent **International Pi Days** you’ll experience in your lifetime. This year I’m looking at Issac Newton’s infinite series approximation for π. Originating in the long ago 1730s, it’s still one of the fastest converging Pi approximations to this day.
