Cengage Learning Astronomy: The Cosmic Journey (Cosmic Journey (with Infotrac, the Sky CD-ROM, and Webtutor)

This hybrid text/Web product is a comprehensive introduction to astronomy, covering all of the major topics in a thorough, yet concise approach. The authors take students on a threefold journey through history (where they see how humans slowly developed our present picture of the universe); through space, from Earth outward (where they see how our expanding frontiers have revealed the geography of our universe); and through cosmic time (where they travel back through cosmic time).. Through these themes, the book's content connects science and the humanities, without treating science as just an assortment of physical facts. The authors thoughtfully link astronomy to human concerns such as stewardship of the Earth and different ways of obtaining knowledge. Astronomy: The Cosmic Journey is comprised of a softcover text and a complete, enhanced, and integrated Web version (via WebTutor Advantage Plus) that will be continuously updated. Review 0.
