Re: EPSILON_ZERO, OK ?

F = K*Q1*Q2/r^2 puts electricity, magnetism and gravity on the
same footing. K is Newton's G for gravity, K_e for electricity, K_m for
magnetism. The "charge" of gravity is mass, coulomb for electricity, and
coulomb (hidden from view) for magnetism. The magnetic coulomb may be
like the color charges of QCD, hidden from public view.
I do not apologize to all who have seen this before.

This list would be silent if things "seen before" were forbidden. Can you
elaborate on the sentence before the last? Magnetic coulomb virtually
disappeared from the introductory textbooks.
