5.0

Enjoyment of reading: 5/5; curiosity provoked: 5/5. I just hope that the explanation of loop may be a bit deeper -- I don't mind having a bit more math if it helps to clarify things. But I guess for a compact book the author has to cut the level of details somewhere.

All in all it's a great little book introducing physics, especially the counter-intuitive and great development of general relativity and quantum physics over the past 100+ years.
