I failed both general relativity and quantum mechanics at university, although the few lectures I sat through in the physics department made much more sense than those in the maths department. Sadly it was the maths department that set my exam! So I enjoy reading about physics as long as I don’t have to memorise tensor calculus as part of it, and obviously picked this up as it is such a popular book on cutting edge physics.
It is very simply seven lessons in physics: each of which takes a well-known issue in modern physics and explains it in lay terms for everyone to understand. From my nemisis, general relativity to black holes and free will, the complexity is cut through a the basic principals explained. Of course if you think you understand some of these principals, you almost certainly don’t, but its nice to have a grasp of what is going on.
A collection of short essays, it comes in at 79 pages of content, so not a big commitment to anyone who wants to understand more of physics. And it is all clear and very well written/translated (from Italian).
