Popper (1972) points out that, though we still believe in the repulsive forces
as being
electromagnetic and still hold Bohr's
theory of the periodic system of elements in a modified form, everything else in this beautiful reduction of the universe to an
electromagnetic universe with two particles of stable building blocks has by now disintegrated.
Nevertheless, many of the greatest physicists, such
as Eddington (1936), continued to believe that with the advent of quantum mechanics the
electromagnetic theory of matter had entered into its final state and that all matter consisted of electrons and protons.

In fact, at the time of Maxwell's death, his
theory of
electromagnetic fields was not yet widely accepted or even well known; experts still argued about whether electricity and magnetism propagated their effects via «action at a distance,»
as gravity (supposedly) did, or by Michael Faraday's «lines of force» (incorporated by Maxwell into his fields).
However, this correlation is distinct from that in the article,
