It can be of no practical use to know that Pi is irrational, but if we can know, it surely would be intolerable not to know.

Edward Titchmarsh

I don’t remember anyone ever mentioning Pi Day when I was in school, but any excuse to celebrate math sounds like fun. March 14 at 1:59 (a.m. or p.m.) is about as close as the calendar can get to 3.14159…
