Quite nice. Thank you!

comment Proof of $\int_0^\infty \left(\frac{\sin x}{x}\right)^2 \mathrm dx=\frac{\pi}{2}.$
Since $\frac{sinx}{x}$ has a limit of $1$ as $x$ goes to $0$, why can't we just say the residue is $0$?

comment Visualizing the group operation in higher homotopy groups
Yes, I'm thinking of it that way too - but why is only one coordinate changed? I would think that all the coordinates need to be changed...

@TaraB, thx - that was bad - they are supposed to be H's.

@ErikG., thx for your comments - I've since then created the proof.
