We are emerging from a period of consolidation in particle physics. Its
great, historic achievement was to establish the Theory of Matter. This Theory
will serve as our description of ordinary matter under ordinary conditions --
allowing for an extremely liberal definition of "ordinary -- for the
foreseeable future. Yet there are many indications, ranging from the numerical
to the semi-mystical, that a new fertile period lies before us. We will
discover compelling evidence for the unification of fundamental forces and for
new quantum dimensions (low-energy supersymmetry). We will identify new forms
of matter, which dominate the mass density of the Universe. We will achieve
much better fundamental understanding of the behavior of matter in extreme
astrophysical and cosmological environments. Lying beyond these expectations,
we can identify deep questions that seem to call for ideas outside our present
grasp. And there's still plenty of room for surprises.Comment: 25 pages, 13 EPS figures, LaTeX with BoxedEPS macros. Closing talk
