I skimmed through the answers and didn't find anything to do with math. To anyone interested in math, what math text/books and papers of the decade seemed the most interesting to you?

As far as fiction, this decade I discovered Peter Watts, Ted Chiang and Clive Barker. Now I am obsessed with horror and sci-fi in the style of these authors. If you are into these genres (and possibly authors), who/what blew you away this decade? Thanks.
