José Maza (Chile) has a degree in Astronomy from the University of Chile and a doctorate in Astronomy from the University of Toronto. He won the National Science Prize in 1999. He has published six books of popular science, the most recent with the title Bajo el manto de Urania, a study of five thinkers who influenced one of the greatest figures in the history of science: Isaac Newton. Urania, the Greek muse of Astronomy, covers us with her cloak of stars in this fascinating work about our efforts to understand a little more about the universe. In conversation with Aldo Bartra.
