Tyson is the most objectionable writer I've encountered all year. I'd like to fill in my science knowledge gaps, in an entertaining way, but he's picking fights with the New York Times (over Pluto as planet) and J.R.R. Tolkien (over the plural form of "dwarf"). It's tiring and self-centered. It's a very bad year when I give out two one-star reviews, but this is a very bad year.
