Are we alone in the Universe? What is our place in it? How did we get here? We have long searched for the answers to questions such as these, and scientists are beginning to find some of the answers. In this beautifully illustrated book, Daniel Altschuler provides the reader with the elements to understand the questions and their answers as far as we know them. He explores subjects from physics and astronomy, to geology and palaeontology. Along the way he touches on topics such as the search for life on other worlds and the hazards of asteroid impacts. Daniel Altschuler is director of the Arecibo Observatory in Puerto Rico. He writes in an engaging and readable style with wit, warmth and erudition at a level that any interested reader can understand.
