  We are now beginning to learn detailed information about cosmological
parameters from the shapes of the matter and radiation power spectra, together
with their relative normalization. As more high quality data are gathered from
galaxy surveys and from microwave anisotropies, the range of allowed models is
expected to get incrementally smaller. The amount of information potentially
available from a high-resolution satellite experiment should allow a
determination of essentially {\it all} currently discussed cosmological
parameters to less than ~10%.
