Do we understand electromagnetics?

And while we're on that path, what stuff is velocity made of?

90% iron, 1% carbon, some polymers.

It's amazing how a simple question can stir up things----


Foundational/fundamental 'unknowns', like electromagnetism/magnetism, have been one of my favorite areas in physics (theoretical) for a long, long time. (we're talking theory here---NOT all of the applied knowledge that is and been known to be used for determinations of problems and situations).
