I did indeed, oops. Anyway, thanks for the replies everybody, obviously I was thinking Feynman diagrams have a physical significance that they don't. Eventually, hopefully, I'll be competent enough to understand some of the mathematics behind them and actually be able to use them! :smile:

Whenever I see examples of the diagram for the Coulomb interaction it always seems to be two electrons interacting via an electron and being repulsed. The diagram looks intuitive in terms of momentum conservation. I was wondering how (for example) a proton - electron interaction, and...
