Hubert Reeves is an astrophysicist whose honours from the scientific community include the Albert Einstein award. But Reeves is known to the public as a wonderful popularizer of scientific ideas, possessed of an exceptional talent at combining science and humanism. As a child growing up near Lac St-Louis in Quebec, Reeves was fascinated by nature and its relationship to the rest of the universe. This fascination led him to Cornell University, where he studied with some of the great scientific minds of the 20th century. A raconteur, Reeves tells stories about his remarkable professors, men like Hans Bethe, Philip Morrrison and Bob Wilson, whose research led to the atom bomb. Reeves also offers revealing anecdotes about Einstein, Niels Bohr, Oppenheimer and Teller. With his usual enthusiasm, Reeves highlights milestones in astrophysics, showing us a view of the moon as seen by Galileo in 1609, and remarkable photos of galaxies colliding billions of light-years away. Along with stunning visuals, we listen as Reeves explains history and theory in a highly accessible way. A committed ecologist, Reeves warns about the deterioration of our planet. In the face of explosive economic globalization, Reeves believes that the globalization of ecological movements offers hope.
