"The twentieth century witnessed the emergence of the disciplines of astrophysics and cosmology, from subjects which scarcely existed to two of the most exciting and demanding areas of contemporary scientific inquiry. There has never been a century in which fundamental ideas about the nature of our Universe and its contents have changed so dramatically…. This is a fantastic story, and one that would have defied the imaginations of even the greatest story-tellers."

–Malcolm Longair, The Cosmic Century: A History of Astrophysics and Cosmology (2006)
