This book explores Relativity and Quantum Mechanics (hence the title). I had a basic understanding of quantum mechanics before reading this, but now I feel I know so much more. The basic principal of relativity is that things can only be measured in reference to other things. The measurements differ depending on your perspective. The chapter also explores the essence of the space time continuum, and things that effect it and are effected by it , i.e., light, gravity, acceleration, time, and mass. Not only are these things connected to the continuum, but are connected to each other in different ways.

I enjoyed this book more than I would care to admit. There were so many interesting things in this book, not to mention great examples, hypothetical and classic. I have read about stuff like this before, but never to this extent. The book explaned things in a certain way that was easy to understand. I highly reccomend it. ( )

Part of the excellent Secrets of the Universe Series. Lofty topics that can reach the average middle school student.
