4.0

I wanted to have to give this book five stars but I couldn’t. I liked the fact that he is presenting his view of physics not yet settled. I liked the references to Democritus and the other ancients. I like the idea of science valuing reliability not certainy. An interesting journey but if the objective of this book is to impart an elementary understanding or appreciation of quantum gravity I’m not sure I wuite got there. I did learn a lot and Rovelli is a great guide to all things quantum. I much preferred his Seven Brief Lessons on Physics.
