Students often take for granted that many of the basic principles of science we study today were once major discoveries that revolutionized the way humans view our planet (not to mention the universe around it!). In this photograph-packed history of major discoveries in Earth and space science, a chronological tour guides readers through the historical progression of how scientists viewed the world. Biographies of key figures–coupled with fact boxes and sidebars that highlight the later implications of each discovery–make this book a fascinating voyage for both science-lovers and laypeople alike.
