Chronology of Science contains approximately 2,000 cross-referenced entries, ranging from 50 to 150 words each, plus identifiers that categorize the entries into core areas (biology, chemistry, physics, marine science, space and astronomy, Earth science, and weather and climate). Also included are introductory and closing essays in each section, sidebars expanding upon important concepts in each time period, figure legends, appendixes directing the reader to further information on specific topics, a bibliography, and an index. This is a helpful reference tool for students looking for basic information about specific scientific events. The entries inspire the reader to investigate the topic further. After reading sections of the book, the reader will have gained accurate information about scientific history, as well as a sense of how scientific discoveries build upon events of the past, and an understanding of the way scientific theories have changed over time.Rezende, Lisa is the author of 'Facts On File Chronology Of Science ', published 2006 under ISBN 9780816053421 and ISBN 0816053421.
