From the reviews:
Gilmore shows us that there's more than one way to shed light on the strange profundities of modern physics and cosmology, and what they have to tell us about the nature of time and space and motion. Black holes, dying stars, traveling backward through time to the Big Bang - they're all here in accessible, instructive and charmingly illustrated retellings. (www.firstscience.com, April, 2004)
For most physicists, the desire to show the public the joys of understanding scientific reality remains unslaked ... . Robert Gilmore has acted upon that desire. Once Upon a Universe ... is the fourth in a series of his books using fairy-tale approaches to communicate important points about physics. ... demonstrates more than one way to shed light on the strange profundities of modern physics and cosmology. ... give the book to your scientist friends. They will thank you for it-and mean it. (Donald Goldsmith, Physics Today, December, 2004)
Physics teachers are always searching for new methods to present, illustrate, and communicate an in-depth understanding of physics to their students. ... In this volume Gilmore tries a different approach as he tells the reader fairy or wizard tales about physics, more specifically, about cosmology. ... physics teachers may find ideas in some of the tales useful in introducing difficult concepts to their students. (Fernande Grandjean and Gary J. Long, Physicalia, Vol. 57 (3), 2005)
This readable book includes six amusing tales. They explain the nature and scale of the Universe, the stars and the galaxies, spacetime and gravity, how the Universe came about, and the life and fate of stars. (Book News on the Internet, March, 2004)
