|A User's Guide to the Universe: Surviving the Perils of Black Holes, Time Paradoxes, and Quantum Uncertainty|
|author||Dave Goldberg, Jeff Blomquist|
|summary||A fun, light read about interesting areas of modern physics that will entertain while it educates.|
A User's Guide covers topics like relativity, time travel, the Standard Model of Particle Physics, and alien life. It does so with a very tongue-in-cheek sense of humor, and footnotes that act as the authors' very own peanut gallery. While this humor lightens up what could otherwise be a few dry areas of discussion, the littering of the text with pop-culture references is bound to make the book feel a bit dated in years to come. For now (March 2010), though, A User's Guide is so fresh you might call it ripe.
Unlike Death from the Skies, this book is well illustrated. The pen-and-ink cartoons are omnipresent, and serve to both illustrate the text, and to take every opportunity for a joke (cheap or otherwise) that presents itself. Overall, I felt that the cartoons were a strong addition to the book, as they can provide a needed laugh in a serious section, or can eliminate the proverbial thousand words when describing an experiment or concept.
The chapter on time travel is a stand-out. It presents several "practical" designs for time machines, which use black holes, cosmic strings or wormholes as components. I am an avid reader of pop-sci books, and I found designs that were new to me. The discussion of the Grandfather Paradox (if you go back in time and kill your grandfather, then you were never born and could never have committed murder) and ways around it are very helpful and present a solid physical framework for thinking about these issues. When the Grandfather Paradox is reformulated using pool balls, instead of thinking humans, it becomes clear that the issues are physical and not metaphysical. Also, the authors helpfully include a chart ranking sci-fi shows and movies for their time travel savvy.
You'll also find a strong and entertaining treatment of inflationary cosmology, including discussions of the evidence behind the theory and a look at some consequences. This book avoids both a heavy technical treatment and a historical look at the development of the theory (see, for example, Alan Guth's The Inflationary Universe for that) and instead dives right in to the juiciest parts. This style is well-suited to the reader who wants the funs bits without all of the baggage.
If you're curious about quantum mechanics, the second chapter contains a one of the best introductions in the field. By asking questions like "can we build a Star Trek transporter?" the authors drive a quick and satisfying tour through the weirdness of the microscopic world. This "evil genius hands-on" approach is this book's most important contribution to pop sci literature, and its most endearing feature. You'll start by looking at Star Trek, but end with the mysteries of the double-slit experiment, wave-particle duality and the uncertainty principle.
Finally, at the end of the book, the authors helpfully include two sets of references: one to the pop sci literature, and one to the technical literature. Many of the best pop physics books of the past are listed, and the bibliography could serve as useful direction to more depth for the interested.
Overall, A User's Guide accomplishes what it sets out to do. It combines a hands-on, question-driven approach to physics with a tongue-in-cheek, pop-culture-based sense of humor. And then it throws on a layer of great cartoons to make the entire package something that most science books aren't: enjoyable. This book is fine, and you may well learn something in the process.
