Cengage Learning Horizons: Exploring the Universe

In this revised and updated Sixth Edition, Mike Seeds has two goals. First, he wants to show students their place in the universe - not just their location, but their role as planet dwellers in an evolving universe. His second goal is to show them how science works. Essentially, "Horizons" can be understood by a principle, organizing theme: the interplay of evidence and hypothesis. Through a discussion of this interplay, Seeds provides not just a series of facts, but a conceptual framework for understanding the logic of astronomical knowledge. A good example of this is how a survey of the solar system in Chapter 16 leads to theories that explain the origin of the solar system, which is followed by further evidence in Chapters 17 through 20 that helps students test and generalize theories. Students reading "Horizons" will not only learn about the vast reaches of the universe, they will gain new insight into the human quest to understand it. To enhance students' learning experience, each new copy of the book includes two CD-ROMs: "The Sky[trademark] Student Edition CD-ROM" and "Voyage Through the Solar System CD-ROM", creating the most complete media package available for an astronomy text.
