From formulas to the periodic table of the elements, from a list of endangered animals to computer terminology, this is an excellent sourcebook of scientific information. You could not find a more comprehensive and readable desk-sized one-volume science encyclopedia. Thirteen chapters cover major divisions of science (e.g., astronomy, biology, chemistry, computer and environmental sciences, technology) listing basic facts, formulas, terms, and processes. One additional chapter lists "useful resources" such as books, organizations, museums, zoos, national parks, and planetariums. This is more of a reference book than the Carnegie Library's Science and Technology Desk Reference (LJ 3/15/93), which contains "1500 answers to frequently asked questions" such as which dog breeds are the most dangerous. Clearly written and well indexed, this will be an excellent reference book for all school and public libraries. Highly recommended for all ages.?Laura E.
