Today, one of the major goals of particle physics is to unify
the various fundamental forces in a Grand Unified Theory
which could offer a more elegant understanding of the
organization of the universe. Such a simplification of the
Standard Model might well help to answer our questions
and point toward future areas of study.
James Maxwell took a big step toward this goal when he
unified electricity and magnetism, and physicists now understand
that at high energies the electromagnetic and
weak forces are aspects of the same force.
In his later years Einstein attempted, but failed, to
write a theory which united gravity and electricity.
