Randall Munroe - What if?: serious scientific answers to absurd hypothetical questions
Same as in How to, it’s a pleasure to see Randall’s thought process when answering absurd but interesting physics questions. The following snippet from the book shows this well:
A mole (the animal) is small enough for me to pick up and throw. Anything I can throw weighs 1 pound. One pound is 1 kilogram. The number 602,214,129,000,000,000,000,000 looks about twice as long as a trillion, which means it’s about a trillion trillion. I happen to remember that a trillion trillion kilograms is how much a planet weighs.
In this spirit, you’ll learn what would happen if you: build a wall looking like the periodic table where each brick is made out of the corresponding element, use a machine gun as a jetpack, lost all your DNA in a split second.
The book both entertained me and thought me more about physics. Randall’s books are the perfect material from which we can teach children that physics is fun.
