I've been meaning for a while to do a post on "Books You Should Read," but I put it off until the last minute (of 2011), so now it's a shopping list. I'm sticking to books that came out in the last year or two, on subjects vaguely related to what we often talk about here on the blog, since I know people get grumpy when we deviate from the prescribed topics of conversation. And I'm trying to highlight books that aren't already bestsellers, but deserve to be; I'm assuming you don't need me to tell you about recent books by Lisa Randall, Steven Pinker, Richard Dawkins, or Brian Greene. (Or me, or my lovely wife.) Note for late shoppers: Amazon will get you all of these in plenty of time for Christmas. And pre-emptive apologies to anyone whose book I didn't include -- probably because I haven't had a chance to read it yet.
How I Killed Pluto and Why It Had It Coming, by Mike Brown. My Caltech colleague Mike Brown is the person most responsible for getting Pluto demoted from planetary status, by discovering Eris and other Kuiper-belt objects. For a long time I thought it was silly to go to such trouble to re-classify a celestical body, but this book convinced me otherwise. Part of the reason is that Brown (or plutokiller on the Twitter) is an enormously engaging writer; few quasi-autographical science books have managed to mix the personal side with the science so effectively.
