From teleportation and space elevators to alien contact and interstellar travel, science fiction and fantasy writers have come up with some brilliant and innovative ideas. Yet how plausible are these ideas--for instance, could Mr. Weasley's flying car in the Harry Potter books really exist? Which concepts might actually happen, and which ones wouldn't work at all? Wizards, Aliens, and Starships delves into the most extraordinary details in science fiction and fantasy--such as time warps, shape changing, rocket launches, and illumination by floating candle--and shows readers the physics and math behind the phenomena.
With simple mathematical models, and in most cases using no more than high school algebra, Charles Adler ranges across a plethora of remarkable imaginings, from the works of Ursula K. Le Guin to Star Trek and Avatar, to explore what might become reality. Adler explains why fantasy in the Harry Potter and Dresden Files novels cannot adhere strictly to scientific laws, and when magic might make scientific sense in the muggle world. He examines space travel and wonders why it isn't cheaper and more common today. Adler also discusses exoplanets and how the search for alien life has shifted from radio communications to space-based telescopes. He concludes by investigating the future survival of humanity and other intelligent races. Throughout, he cites an abundance of science fiction and fantasy authors, and includes concise descriptions of stories as well as an appendix on Newton's laws of motion.
Wizards, Aliens, and Starships will speak to anyone wanting to know about the correct--and incorrect--science of science fiction and fantasy.
Charles L. Adler is professor of physics at St. Mary's College of Maryland.
"To only call Wizards, Aliens, and Starships engaging would be a real understatement--it is a delightful, funny, and immensely interesting romp through science and fiction. From candlepower to teleportation, all the way to the fate of the cosmos in the span of a googol years, this is a cornucopia of teachable material. It is also a reminder of the simple thrill of applying science to the world around us, real or imagined. A new classic."--Caleb Scharf, author of Gravity's Engines and The Copernicus Complex
"This terrific book analyzes the romantic ideas of science fiction using the hard-nosed reality of the laws of physics. It will interest all readers, from Star Trek enthusiasts to astrophysicists."--Paul Nahin, author of The Logician and the Engineer
"Wizards, Aliens, and Starships rigorously applies the principles of physics to concepts, plot devices, and other features of science fiction and fantasy books, films, and television series. Readers who follow Adler's carefully developed analyses will learn a great deal about familiar science fiction tropes, physics, and how scientists think about the world. An exceptional book."--A. Bowdoin Van Riper, author of Science in Popular Culture
