comment Graph of electric potential
The plot you have for electric potential is drawn for a point-like charge. For a finite sized charged particle the field inside the charged particle indeed does not diverge. For example for a hollow sphere with some charge, the potential is constant inside the sphere and outside the sphere follows the behavior shown in your figure.

comment Proof that eigenvalues of Fermionic creation/annihilation operators are Grassman numbers
From the books at my hand at the moment at least Altland & Simons "Condensed matter field theory" and Peskin & Schröder "Introduction to QFT" do this.

comment Proof that eigenvalues of Fermionic creation/annihilation operators are Grassman numbers
I'm not sure if I understand this explanation, but this is probably just my own ignorance since I don't know anything about supermanifolds. Can you recommend any sources for reading about this stuff?

comment Intuitive explanation to why superconductivity breaks at high temperatures
Actually if I think about it, my question could be rephrased as: why is there a temperature dependence in the gap? Yes, I can see from the gap equation that there is, but how would you interpret that information?
