Today’s π day. March 14 is 3/14 and π is 3.14…. 3.1415926535 was as far as I cared to memorize, and even that was a waste of time.

This is a perfect day to share any π-related stories. My favorite is the day I learned about radians as an angle measurement and that a circle was 2π radians. 11th grade, I think. That had a profound effect on my future development as an adult.

Additional reading: piday.org is supposed to be the “official” π day site (at least, it’s the first site that showed up in Google).
