Progress and Frustration in Cosmology Lecture by Martin Rees
Abstract: It is gratifying that some of the key numbers describing our Universe have been measured to a precision of a few percent. We are learning about the emergence and properties of galaxies, stars, planets and life -- and how this chain of events depended on these numbers. These advances have sharpened up new mysteries. Some of these will be clarified by new observations; others, such as the overall scale of the universe (and whether we inhabit a multiverse) are likely to prove frustratingly intractable.
