In the entire literature of physics textbooks, there is hardly another work that holds such an undisputed top position in its field as Jackson's book on electrodynamics, and this has been the case for four decades. The German translation of this classic in theoretical physics is now being released in a thoroughly revised new edition. This makes theoretical electrodynamics more comprehensible than ever before. The uniquely high number of specifically calculated examples, precisely worked-out cases, and numerous exercises remains unmatched. Since the third edition, the book has mostly been written in SI units. Its practical relevance (also to experimental physics) is appreciated by students, scientists, university lecturers, and engineers alike.
