Writing books about "The [Something] of Star Trek" seems to have become something of a fad ever since Lawrence Krauss's wonderful "The Physics of Star Trek," whether that "Something" be biology, philosophy, religion, or, in this case, computers. This book becomes tiresome, or at least off-topic, largely because there is a dearth of primary-source material on the computers of Star Trek, meaning that there is unfortunately little for the authors (who are computer scientists) to analyze scientifically. Specifically, the authors' primary sources consist of a scant smattering of material from the television shows and movies and the "Star Trek: The Next Generation--Technical Manual." To quote the book, "The technical manual devotes only five pages to the Enterprise computer. Based on its vague and sketchy description, we've inferred [a] general design." In other words, the book is based largely on assumptions and inferences, some of which are rather nonsensical. For example, in reference to the Star Trek memory storage unit known as a "kiloquad," the book says, "it's easy enough to deduce...that a kiloquad equals 1,000 quadrillion bytes." The only "evidence" given to support this conclusion is that "kilo-" means 1,000 and that "Checking a dictionary reveals that the only numerical term involving quad is quadrillion." This kind of speculation would be mildly interesting if only a paragraph were devoted to it, but instead, the authors assume throughout the remainder of the book that this is the definition of a kiloquad, and analyze the plausibility of data storage space on this extremely tenuous basis. This is after quoting the following wise excerpt from the "Star Trek Encyclopedia:" "The reason the term was invented was specifically to avoid describing the data capacity of Star Trek's computers in 20th century terms." This is one of countless examples. Much of the book seems to consist of the authors making unconvincing inferences, repeating themselves when they run out of source material, and making occasional (and unsuccessful) forays into philosophy and physics. The book is interesting when it makes a real point, but has too much filler material. There simply isn't enough source material for a 200-page book of this sort to be successful.
