Last week I found out that the Basel problem was actually the inspiration for the Riemann Zeta function: http://www.fermatslibrary.com/s/a-proof-that-euler-missed#em...

eusebioon A note on Euclid's Theorem

I feel Euclid's Theorem has an enormous number of different proofs considering the importance of the Theorem.

eusebioon Feynman’s proof of the Maxwell equations

He is not claiming that the commutator is equivalent to the divergence, what he is saying is that [xl',Hl] = 0 is equivalent to div H = 0, which is different. If you click on the annotation on the left you will see that [xl',Hl] = 0 means that Hl is not a function of xl and so ∂_lH_l will be zero and consequently div H = Sum ∂_lH_l is also zero.
