Understanding Physics (Hardback or Cased Book)

Part of the best-selling "Understanding" series that brings to life the wide world of physics. Rather than explaining details about how to do physics, this book focuses on explaining what different branches of physics are about, how we know about them, and what mysteries remain for budding physicists to uncover. It doesn't shy away from the hard stuff, tackling black holes, quantum mechanics and even Einstein's theories of relativity.
