What If?: Serious Scientific Answers to Absurd Hypothetical Questions

by Randall Munroe

We keep trying to make our units of measurement make sense. But the truth is that the world is an absurd place; why not embrace it? It’s true, unit conversion errors have caused us to lose space probes once in a while. But isn’t that a small price to pay for silliness?

That means that when your arm is still rotating toward the correct position, the signal to release the ball is already at your wrist.
