And of course there’s one more book I’d like to plug: my own The Chemistry Book. I’m putting it in a separate post both for the personal glory and because I don’t think that Amazon likes it too much when you try to rake in affiliate fees from a book that you’re already getting royalties on. At any rate, I am not an unbiased observer, but I think it’s a worthwhile gift for anyone who might be broadly interested in this stuff. I’ve had a lot of feedback over the past few months since its publication, and have been glad to hear that all sorts of non-chemist readers seem to have enjoyed it. Buy several, just in case.
