This advanced undergraduate- and graduate-level text by the 1988 Nobel Prize winner establishes the subject's mathematical background, reviews the principles of electrostatics, then introduces Einstein's special theory of relativity and applies it throughout the book in topics ranging from Gauss' theorem and Coulomb's law to electric and magnetic susceptibility.
Not a fan of the sexism, the math was a bit beyond me, I liked the particle and classical treatment of the electron and thought it was impressive how much could be done with a few simple assumptions. The book is very abstract (intentionally) so I could have used more concrete examples but I might have just been over my head here.
