What book(s) are you currently reading or listening to? October 21

Started What If? by Randall Munroe.

It's by the guy who runs / draws xkcd.com web comics, and gives serious scientific answers to absurd hypothetical questions. For example: Is it possible to build a jetpack using downward firing machine guns?

Questions are weird like that, but the science is real, so an interesting read. Specially if you are a fan of xkcd.

What about all of you? What have you been reading or listening to lately?
