THE SUNDAY TIMES NUMBER ONE BESTSELLERFrom the creator of the wildly popular xkcd.com, hilarious and informative answers to important questions you probably never thought to ask.Millions visit xkcd.com each week to read Randall Munroe's iconic webcomic.

Fans ask him a lot of strange questions: How fast can you hit a speed bump, driving, and live?

When (if ever) did the sun go down on the British Empire?

When will Facebook contain more profiles of dead people than living?

How many humans would a T Rex rampaging through New York need to eat a day?In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations and consults nuclear reactor operators.

His responses are masterpieces of clarity and hilarity, complemented by comics.

They often predict the complete annihilation of humankind, or at least a really big explosion.

Perfect use of the medium in translating this from the web to a physical book.

Review by

My XKCD fandom was apparently so obvious that I got this book as a present without it being on my explicit wishlist. Interesting and readable it is and I am impressed by the breadth of Randall Munroe's physic knowledge. The book is not particular funny as XKCD, does not delve into a narrative and focuses on physics and scientific issues, rather than the human issues of XKCD comics.
