It was pretty late last night when I finished my post about blogging with WordPress and Dexy, so I didn’t even notice it had turned into π day. This morning of course twitter reminded me, and in particular this caught my eye:
Can anyone draw me a plot of √[6(1 + 1/2^2 + 1/3^2 + 1/4^2...)] →π? Excel is not only ok, it’s recommended. Should bounce around and close in.
