Re: EPSILON_ZERO, OK ?

Everything works the same, you just don't have monopoles.  The lowest
multipole for a static B-field is the dipole.  Electricity and magnetism
are coupled through the "curl" laws.

All this is in the spirit of Feynman, as expressed in the Mechanical
Universe (the one by Olenick, et al) where the 3 force laws are introduced
in the mechanics part of the course (makes sense, because the 3 are all
alike), and one can begin arguing a child's version of Gauss' law while
discussing the strength of gravity in bore holes (inside the earth).

Modify the above, where I said "you don't have monopoles".  We may have
monoopoles, it's just that nobody has seen one - yet (there are searches).

Adam was by constitution and proclivity a scientist; I was the same, and
we loved to call ourselves by that great name...Our first memorable
scientific discovery was the law that water and like fluids run downhill,
not up.
