Is the delta function shown in that other page the Dirac delta function, or a different one? Sorry, I have only looked at what that is a little bit, but I think it is based on what I remember. Anyway, if it really is, you should put that in there, or make it more clear.
Frankly, your "Math is too rigorous, let's just look at the Physics" is confusing, at least to me. For me, it is the least confusing when someone explains things rigorous first, and then gives the shorthand, or "abuse of notation", which they can use from there on. But maybe that is just my mathmatition-ness speaking. Also, your quotes should be done in LaTeX style, i.e., ``Backticks first, single quotes last''.
