Pi Day is March 14, due to its 3.14 notation.  This week on the Buf, we discuss all things pi-related, including interesting pie words, the history of the precision of estimates of pi, how to think about radians, and why thinking about a different circle constant (namely tau := 2*pi) might help get your head around some of these ideas.
