First, CSS points out that Maxwellian electrodynamics, relativity theory and quantum theory stand upon an incorrect model of the atom or charged particle. Specifically, are electrons (and other charged particles) mathematical points or small spinning units of charge? It seems perplexing to think that physical properties can be modeled by such radically different (physical?) concepts, but perhaps that accounts for the enormous complexity and non-classical notions in relativity theory and quantum theory.
Quantum theory obviously is impacted by the difference between mathematical points and spinning units of charge. On the other hand relativity theory is concerned with electric and magnetic fields, where the high speed interactions of charges and fields are impacted by the difference between points and spinning units of charge.
