Why Stuff Falls Down: The Story of Science and Gravity From Aristotle to Einstein Told in Plain English

Why Stuff Falls Down is the story of how we have understood gravity, from the time of the ancient Greeks right up to the current efforts to unify Einstein’s gravity with quantum mechanics.

It’s also the story of science. How did science grow to be the way it is today? What’s the difference between a fact, a wild idea, and a scientific theory? And what’s this scientific method they talk about?

This book is written in plain English, with a minimum of nerdy jargon. This story is for anybody curious about what we know, and how we know it. If that sounds good to you — then you are who I wrote this book for!

Why Stuff Falls Down has over half a dozen you-can-do-this-at-home activities for everything from “what direction is down” to how lightspeed trades off between space and time, and demonstrating for yourself how light travels as a wave!

Bonus Material: Quantum mechanics in plain English? Ya gotta read it to believe it.
