What If?
What If?: Serious Scientific Answers to Absurd Hypothetical Questions
By: Randall Munroe
Super interesting, very funny.
I love my science with a side of comic! His drawings might be better than his explanations.
Plus who doesn't enjoy random useless facts that you can say to blow people's minds and feel incredibly smart?
For example:
What if everyone only had one soulmate?
How fast can you hit a speed bump while driving and live?
What would happen if the moon went away?
Are fire tornadoes possible?
What height would you need to drop a steak from for it to be fully cooked when it hit the ground?
What would happen if everyone on Earth stood as close to each other as they could and jumped, everyone landing on the ground at the same time?
Highly recommend this (for sure every science teacher should own this)- even if you don't love science. Just gloss over the equations, you'll still get the point.
