6870 Pauldavies           Discovered 1992 July 28 by R. H. McNaught at Siding Spring.
Named for Paul C. W. Davies (b. 1946), a British mathematical physicist resident in Australia, with research interests in cosmology, quantum gravity, astrophysics and the origin of life, who also has an international reputation as an author and broadcaster. His books range from the scholarly Quantum Fields in Curved Space (with N. D. Birrell) to the popular About Time. He has a long-standing interest in the relationship between science and theology, summarized in his well-known book The Mind of God. His contributions to this field were recognized in 1995 with the award of the Templeton Prize for Progress in Religion. Davies has been a vociferous supporter of the need for search programs for near-earth objects. Name proposed and citation prepared by D. I. Steel and the discoverer.
