[95.01] Closing in on the Cosmological Parameters

M. Tegmark (University of Pennsylvania)

I describe the sharp constraints on cosmological paramaters placed by recent measurements of the cosmic microwave background, galaxy clustering, supernovae, etc., and how different types of measurements now allow powerful cross-checks to be made. I also comment on outstanding puzzles in the emerging cosmological ``standard model'' and upcoming measurements that may resolve them.
