"Reality Is Not What It Seems: the path to quantum gravity".
I was enthralled. He writes very entertainingly about the long history of scientific thought, from Democritus forward. He also explains to the educated layman both relativity and quantum theory well enough to show where they are incompatible. His description of the concept of fields clarified my thinking significantly.
He then goes on to "explain" the contributions of loop quantum gravity, especially the quantization of space-time.
I actually got a chill when he showed the expression for the "Bronstein" length, sometimes called the Planck length, the smallest dimension possible. It is simple, contains, c the speed of light from relativity, h, Planck's constant, from quantum mechanics and G from Newton's square law, math operators square root, exponent cube, and pi, the ratio of circumference to diameter of a circle, times 2. Brought it all together. He does not claim all is complete, but only that this looks to be worthy of spending big bucks to find evidence.
My arcane enthusiasms are not for everyone; but IMHO it is very well written.
