Notes

• One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. Here, physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future. From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals–and the limits–of the laws of physics as we know them today. He ranks the impossible technologies by categories–Class I, II, and III–depending on when they might be achieved, within the next century, millennia, or perhaps never. He uses his discussion of each technology as a jumping-off point to explain the science behind it.–From publisher description
