Okay, I'm a big Michio Kaku fan. I listen to his radio show, Explorations, almost every week. I just finished reading Physics of the Impossible, A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel and I really enjoyed it. I never studied Physics in school; learning more about Physics has been like a hobby of mine and Kaku does an excellent job at explaining the theories behind each concept. The more I learn about Physics the more I feel like I want to switch my major, (I'm an Econ major now) and just study physics since that's what I love learning about anyway. But I digress; I loved this book because it tackled all kinds of theories in Physics and discussed the history and possible future of each of them.
