The Mystery of Gravity

Gr 5-8-Informative overviews with colorful captioned photographs, drawings, and charts on almost every spread. In a pleasing layout and readable format, the texts define key concepts in their field of study. Gallant presents a well-balanced discussion on the importance of biodiversity and the mass extinctions that are occurring due to habitat loss and other factors. He also discusses such topics as species interdependence and the different ecosystems. This title would pair well with Dorothy Hinshaw Patent's Biodiversity (Clarion, 1996). Parker begins by presenting the beliefs of Greek philosophers such as Pythagoras, Plato, and Eudoxus. He continues by explaining how scientific theories concerning gravity have changed over the years and concludes by discussing more recent scientists such as Albert Einstein and Edwin Hubble. Concepts in gravitation are also presented, including the Big Bang theory and the study of black holes. Both titles are useful additions.-Maren Ostergard, Bellevue Regional Library, WA Copyright 2003 Cahners Business Information.
