comment What is meant by potential energy for a particle in a field?
yes, I would tend to agree with your view and summarise it as work-done on system + potential energy of system + kinetic energy of interacting particles = const. But does the idea of a point in the system having a potential make sense then?

comment Does an oscillating electrical monopole radiate?
@RonMaimon +1 your answer is an interesting alternative view of an oscillating electrical monople as a continuous membrane of charge, and the non-radiation condition isn't universally known even today.

this doesn't answer the question and shouldn't be up voted.

comment How did Einstein derive general relativity?
Mach's principle, the equivalence principle and the Ehrenfest paradox all played a part.

comment What's the core difference between the electric and magnetic forces?
An electric field doesn't do work on charge moving normal to it.

comment What is the difference between manifest Lorentz invariance and canonical Lorentz invariance?
The action requires the definition of a time coordinate as well. I guess you mean the Lagrangian is chosen such that the action is Lorentz invariant which is easy to show.

comment Does this Zeilinger group result provide experimental proof of backward-in-time causation?
"backwards in time" is this another name for reversing the order of events compared to "forward in time"?
