What is a good textbook that gives a basic understanding of quantum electrodynamics? My university doesnt have any courses in this subject so Im gonna have to teach to myself. What do I need to know and understand before I dig down into quantum electrodynamics? So far I am at my second year of undergrad studies and I have only taken a introductionary course in quantum physics but some pretty extensive courses in electromagnetic fields and newtonian mechanics. I have not yet taken any courses in quantum dynamics or quantum mechanics. Would it be pointless to try and understand QED before I have taken those courses??
