What If? Serious Scientific Answers to Absurd Hypothetical Questions

How could we build a Lego bridge between London and New York? When will Facebook contain more profiles of dead people than living? How fast can you hit a speed bump while driving and live? What would happen if everyone on earth jumped at the same time?

Randall Munroe answers weird and wonderful hypothetical questions, applying serious scientific knowledge and methodology: differential equations, computer simulations and declassified military research are all enlisted in the pursuit of satisfying, clear and often hilarious solutions. So, if you have ever wondered whether you could actually live on an asteroid like Antoine de Saint-Exupéry's Little Prince, or pondered what would happen if the sun suddenly switched off - or indeed if you have children and need expert help to maintain your position as font of all knowledge - this is the book for you.
