Hi...I am talking about the nonmathematical conceptual books that no physicist or the person interested in physics should miss out. They have characteristics such as easy to follow, fundamental, "can't leave the book" effect, etc. 1. The Elegant Universe by Brian Greene 2. The Fabric of the Cosmos by Brian Greene 3. The Universe in a Nutshell by Stephen Hawking Now, I am sure I missed tons more....but I loved these...so tell me more guys.
