UNIFIED FIELD THEORY

Classical attempts at devising a unified field theory, principally those
of Einstein, were concerned with the combination of gravitation (the
general theory of RELATIVITY) and electromagnetism into the same
theoretical framework. Electromagnetism is described by MAXWELL'S EQUATIONS
for an antisymmetric tensor, whereas Einstein's theory of gravitation
centers about a symmetric metric tensor; Einstein's idea was to combine
both descriptions into a single, nonsymmetric tensor, thereby treating both
subjects ...

while the other
three, identified with the quanta that transmit the weak interaction, are
estimated to be quite heavy. Their rest-mass energies are on the order of
50 to 100 times the mass of the proton, and their observation should become
possible with the next generation of high-energy accelerators. So far, the
Weinberg-Salam theory has passed every unambiguous test to which it has
been subjected. Weinberg and Salam shared the 1979 Nobel Prize for physics
for their model.

Many other unified theories, involving strong interaction and even
gravitation, have recently been proposed. Such grand unification schemes to
date have unavoidable and questionable consequences, such as the ...
