What If? Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe
Review
The stories were good, fun and they read like the alt-text on the xkcd comics. I have to say that the form of a collection as a book does not work as well for me, I tend to get “saturated” with this type of content quickly and I would like consuming this kind of content one story at a time instead of reading it all after another in book form.
