Why not? Same thing with when near an electrostatic field that raises
up the hair on my arm, I know that I have run across a field by what the
definition of a field is.

Better yet..., his 1861 paper "On Physical LInes of Force" which I host
on my website.

I'm following Volovik's lead about this. Volovik says it like it is
very well in his book "The Universe in a Helium Droplet" page 461 sect.
33 Conclusion;

"According to the modern view the elementary particles (electrons,
neutrinos, quarks, etc.) are excitations of some more fundamental medium
called the quantum vacuum. This is the new ether of the 21st century.
The electromagnetic and gravitational fields, as well as the fields
transferring the weak and the strong interactions, all represent
different types of collective motion of the quantum vacuum."

As far as I am concerned, Maxwell was way ahead of his time. With the
advent of the Standard Model and its Higgs field, we really have come
full circle back to Maxwell's aether. However, the ether is much
different now than what was envisioned at the time. I suspect the Higgs
field of the Standard Model will need quite a bit of modification.
Hopefully the LHC will give us the clues needed. And I believe some
clues have already been popping up in various experiments.

Sure.

Why do you think fields have to be continuous? They don't. That is why
we have quantum field theory. So what if Maxwell's fields are a "sum"
of quantum fields. They are still fields.
