Originally written in 1964, this famous text is a study of the classical
theory of charged particles. Many applications treat electrons as point
particles. At the same time, there is a widespread belief that the theory of
point particles is beset with various difficulties such as an infinite
electrostatic self-energy, a rather doubtful equation of motion which admits
physically meaningless solutions, violation of causality and others. The
classical theory of charged particles has been largely ignored and has been
left in an incomplete state since the discovery of quantum mechanics. Despite
the great efforts of men such as Lorentz, Abraham, Poincare, and Dirac, it is
usually regarded as a "lost cause". But thanks to progress made just a few
years ago, the author is able to resolve the various problems and to complete
this unfinished theory successfully.
