Nicolaus Copernicus: Making the Earth a Planet
Grade 9 Up–As a man of the Church, Copernicus was never aware of the impact of his ideas on the world. After a lifetime of figuring, observing the heavens, and studying classical theories, it was finally mathematics and his quest for an elegant solution that led him to conclude that Earth was a planet orbiting the sun. The era and events in which he lived are chronicled as the authors describe Copernicus's life and efforts to explain the rotation of the planets. However, the detailed descriptions of his process and the explanations of theories are difficult, and it might take readers with an advanced degree in mathematics to understand the specifics. Numerous diagrams illustrate the concepts; additional art includes woodcuts, details from period books and paintings, and photographs. All are helpful and appropriate, but unsourced. Also, the narrative flow suffers when five titled sidebars have nothing more than a border to distinguish them from the main text; the instructions to proceed to nonsequential pages are frustrating. For students seriously interested in astronomy and how Copernicus solved the riddle of the heavens, this is a valuable resource. For those wanting an overview, this book is too complex.–Janet S.
