If nobody has bothered you about this yet, then you need more nerdy/educated/informed/mathy/numerically-involved/odd/(other names here) friends. Because today, March 14, is Pi Day. There are multiple levels to this day: March 14th (3.14), Albert Einstein’s birthday is today (the guy who did not come up with Pi, but did eat pie), also some stuff found here.
So, celebrate Pi Day with some pie! I would like to offer this graph (my favorite pie related graph) in honor of today.
