Science of Star Wars

Likely to have lasting appeal . . . This is an unusually rich, diverse, and reasonable analysis of the scientific questions raised by the Star Wars series . . . Sigh, if only Jeanne Cavelos had been my teacher. -- San Francisco Examiner This book is for all of us who wonder why jumping into hyperspace isn't like dusting crops on Tatooine . . . Appealing and accessible. the scientific research presented is the mainstream of current thinking in astrophysics, cosmology, robotics, genetics, and biological adaptation. -- The Christian Science Monitor The author examines five major areas--planetary environments, aliens, druids, space ships and weapons, and the Force--in sufficient detail to satisfy even knowledgeable fans.

Cavelos engaging style makes this book a treat, with no science background necessary. -- Publishers Weekly Cavelos, an astrophysicist, mathematician, writer, and teacher, examines the science behind George Lucas's popular series of movies, comparing his fictional universe with the universe as we currently understand it. She points out that in the two decades since the debut of Star Wars: A New Hope, scienc
