Galileo and the Magic Numbers

by Sidney Rosen

Sixteenth century Italy produced a genius who marked the world with his studies and hypotheses about mathematical, physical and astronomical truths. His father, musician Vincenzio Galilei said, “Truth is not found behind a man’s reputation. Truth appears only when the answers to questions are searched out by a free mind. This is not the easy path in life but it is the most rewarding.” Galileo challenged divine law and the physics of Aristotle, and questioned everything in search of truths. And it was through this quest for truth that he was able to establish a structure for modern science.

About The Author

Sidney Rosen is presently professor emeritus of astronomy at the University of Illinois. He still teaches in a special undergraduate program called Unit 1. His field, however, is not astronomy, but the history of science. When he finished his doctorate at Harvard in 1955 (on the GI Bill), Rosen’s wife, Dorothy, a children’s librarian in the Boston Public Library at the time, persuaded him to write a book about Galileo, and to his surprise, Little, Brown bought it. The book received good reviews and went through sixteen printings. The success of this book sparked similar bios of the great early Renaissance physician Paracelsus, who is considered the “father of chemotherapy”; the astronomer Johannes Kepler, who first worked out the planetary orbits; and R. Buckminster Fuller, designer of the geodesic dome.

Rosen has a bachelor’s degree from what is now the University of Massachusetts at Amherst. Rosen was in the Army Air Corps Medical Department during World War II. He and his wife have written about fifteen publications, some of which they coauthored. Their latest publication is the Belle Appleman adult mystery series, which includes Death and Blintzes and Death and Strudel, all of which take place in Boston during the Great Depression of the 1930s.
