Written with college students in mind, this reference offers a nonmathematical introduction to cosmology, designed to be accessible to nonspecialists. It begins with an overview of early ideas about the universe, from the ancient Egyptians to the modern era; the rest of book covers the 20th century and the early 21st century. Thematic chapters cover topics such as the large-scale structure of the universe, the discovery and importance of cosmic microwave background radiation, and the forces and particles involved in the evolution of the universe. Each chapter concludes with a list of print and electronic resources, and an annotated general bibliography at the end of the book lists general works or those of particular significance. Sidebars provide more in-depth information on key people and ideas without interrupting the flow of the main narrative. A glossary of scientific terms is included. The book's 66 b&w illustrations and images are more technical rather than awe-inspiring. Ratcliffe teaches cosmology at Wichita State University.
