Read in the comments to Yglesias’s blog:
Going to popular/mass publication journalist-written books for an introduction to a country is a bit like taking Newtonian physics: it will get you some of the basic generalizations, but once you get more in depth you realize how wrong your introduction was.
I wonder if the person who wrote this actually took Newtonian physics. My understanding was that under most conditions people encounter in their day-to-day lives (i.e. you’re moving significantly slower than the speed of light and you’re larger than an electron and smaller than a black hole) Newtonian mechanics are quite accurate. I took several physics classes and I don’t remember the class where the professor said “OK class, that F=ma thing? We were lying about that.”
