Hi Pete and Hans.

Hans has an excellent diagram 16.1 I've been
studying, Pete, how about rendering an opinion.
Ken

That's from chapter 16 on the Hamiltonian and
Lagrangian densities:http://physics-quest.org/Book_Chapter_Lagrangian.pdf

There's a significant update on the derivation
of the Lienard-Wiechert E & B fields demonstrating
that the E field points towards the extrapolated
position instead of the retarded position.http://physics-quest.org/Book_Chapter_EM_LorentzContr.pdf

Thanks Hans. I admire Fig 2.5, it makes
good sense seeing it that way. I was
thinking of a radiating or receiving antenna
dipole while reading it, but then you used
the Sun as a radiation emitter and the location
of it's gravitational influence perfectly.
It's good to see a bigger picture.

I made a similiar argument on Apr.8 in this
thread using GR geodesics, accounting for
aberration and rotation, but didn't apply
it to electric fields.
