Dynamics of a charged particle.

Using physical arguments, I derive the physically correct equations of motion for a classical charged particle from the Lorentz-Abraham-Dirac equations (LAD) which are well known to be physically incorrect. Since a charged particle can classically not be a point particle because of the Coulomb field divergence, my derivation allows for that by imposing a basic condition on the external force. That condition ensures that the particle's finite size charge distribution appears as a point charge to the external force.

Time reversal invariance and the arrow of time in classical electrodynamics.

Time reversal invariance, T, is well known to hold in quantum electrodynamics. However, it has caused difficulties in classical electrodynamics (CED). These are shown to be conceptual misunderstandings.

Facing quantum mechanical reality.

Two recent precision experiments provide conclusive evidence against any local hidden variables theory and in favor of standard quantum mechanics. Therefore the epistemology and the ontology of quantum mechanics must now be taken more seriously than ever before. The consequences of the standard interpretation of quantum mechanics are summarized in nontechnical language.
