There are a lot of “The Science of…” books out there using science fiction as a means to explain science. It’s easy to see the appeal for both readers and writers. For one thing, it makes complex and technical subjects approachable and palatable. For another, it provides a series of examples with which most readers will already be familiar. Triggering memories of a beloved book can’t hurt sales.
This “Science of” book is a little different in that it uses a work of absurdist humor as its muse. [In the unlikely event that you’re unfamiliar with Douglas Adams’ “The Hitchhiker’s Guide” series, you can access a review here.]One may wonder whether the book delves into this absurdity by contemplating the efficiency of infinite improbability drives (faster than light engines that run on unlikelihood) or the value of melancholy robots. It does and it doesn’t. For the most part, it relates the wildest creations of Adam’s mind to the nearest core notion that has scientific merit. [Though it does have a chapter on babel fish (an ichthyologically-based universal translator), but that’s a technology that’s already in the works—just not in fish form, but rather a phone ap.]
For the most part, the book explores science and technologies that are popular themes in the pop science literature. These include: the existence of intelligent extraterrestrial life, artificial intelligence, the end of the world, the beginning of the world, time travel, teleportation, cows that don’t mind being eaten (presumed to take the form of lab-grown meat, and not talking cows who crave flame-broiling), the simulation hypothesis (as related to Adams’ Total Perspective Vortex), parallel worlds, improbability (only tangentially related to the infinite impossibility drive, i.e. focused on understanding extremely unlikely events), and the answer to the ultimate question. There is also a chapter that I would argue is more in the realm of philosophy (or theology, depending upon your stance) than science, and that’s the question of the existence of a god or gods. (This isn’t to say that the question of whether god is necessary to explain the existence of the universe and our existence in it isn’t a question for science. It is. But Hanlon mostly critiques the numerous arguments for why there must be a god, and it’s easy to see why because they provide a lot of quality comic fodder.)
The book contains no graphics, but they aren’t missed. It has a brief “further reading” section of other popular science books, but it isn’t annotated in the manner of a scholarly work. It is well-researched and highly readable, not only because it hitches its wagon to Adams’ work but also because it’s filled with interesting tidbits of information and its own humor. The book was published in 2005, and so it’s a little old, but most of the technologies it explores are so advanced that the book has aged well. (But if you want the latest on a particular aspect of science fiction-cum-science, you may want to look at a more recent book.)
I’d recommend this book for fans of “The Hitchhiker’s Guide to the Galaxy,” and those interested in popular science generally. (Having read the five books of Adams’ “Hitchhiker’s Guide” trilogy will make the book more entertaining—though it’s not essential to make sense of it.)
