TITLE: Geometric Interpretation of the Basel Problem?
QUESTION [17 upvotes]: Does the Pi in the solution to the Basel problem have any geometric significance?  Every time I see Pi, I have to think of a circle.  I would love to see a nice intuitive picture connecting the Basel problem with geometrical figures.  Anyone here been lucky enough to stumble upon such a thing?
