Institute Scientist, Solar System Science and Exploration Division, Southwest Research Institute in Boulder, Colorado.

The history of cosmology is not the easy story of the rejection of absurd ideas in favour of what (perhaps after a little thought) is seen to be patently true, but the heroic saga of the hard-won rejection of the patently true in favour of the absurd.
Michael Hoskin, 1997, The Cambridge Illustrated History of Astronomy
