  Cosmology is very exciting for three reasons. There is a very successful
standard model - the hot big bang - which describes the evolution of the
Universe from 10^{-2} sec onward. There are bold ideas, foremost among them are
inflation and cold dark matter, which can extend the standard cosmology to
within 10^{-32} sec of the bang and address some of the most fundamental
questions in cosmology. There is a flood of data - from determinations of the
Hubble constant to measurements of CBR anisotropy - that are testing inflation
and cold dark matter.
