Happy Pi Day! I think it's a pi inuksuk, but I can't be sure. For those of you who aren't nerds, pi is an irrational number which helps us find things like the circumference and area of a circle. Since it starts off as 3.14159 all of us math lovers celebrate it as an excuse to eat pie on 03/14 or March 14th at 1:59pm. Come to the nerd side ... we have pi.
