This read was pretty interesting, for a book about arcane physics! Not being a physicist didn't stop me from understanding any of the material presented, either. It was all explained in easy language meant for non-physicists. It was also a pretty good story about the hows and whys wrapped around the actual physics parts. Well narrated, too, without the usual scientific dryness one would expect from a textbook. I recommend this if you have any interest in how things work.
