Best "Nontechnical" Physics Books Does anyone have any suggestions on some good nontechnical books on physics? I want to know more about the history of science, lives of the scientists, etc., but I'm not necessarily opposed to something with equations and discussion on theories either. What I really mean by nontechnical is anything that isn't a formal paper or textbook. I'll read about any topic really, but right now I'm interested in the less mainstream type of theories. Not futuristic Kaku type science fiction-science, but just lesser known ideas. I know I could search on Amazon and get some good results, but I'm looking personal suggestions. Help me out?
