Review by Michael Beach
As the title and subtitle suggest, Michio Kaku considers the stuff of science fiction and considers them from science as we know it today. Taking the mantra that “the ‘impossible’ is relative” (Kaku, 2008, p. xi), he breaks the various sci-fi ideas into categories. Class I impossibilities “are technologies that are impossible today but that do not violate the known laws of physics” (Kaku, 2008, p. xvii). Class II impossibilities “are technologies that sit at the very edge of our understanding of the physical world” (Ibid.). Class III impossibilities “are technologies that violate the known laws of physics” (Ibid.).
Michio Kaku goes on to describe difficult scientific ideas in ways that a novice like me can understand. He looks at each technology, explains the sort of science involved, and the new technology or science that would have to be developed. For each technology he then makes an argument for which category each technology would belong to. I found the approach framed well and the arguments convincing. It’s a really interesting way to a non-scientist like me to get a glimpse into the world of scientific thought.
