Abstract
We review the status of attempts to measure the present cosmological expans ion rate No and to estimate the cosmological density parameters for neutrin os baryons, nonrelativistic matter and vacuum energy. While the total densi ty appears to have a 'reasonable' value near the critical density, the four components have mysterious values that require an explanation from fundame ntal physics.
