It is no exaggeration to say that they changed the world. Without them, we couldn’t have built the automobile, invented the jet plane, or put a man on the moon. Of course, Newton’s writings didn’t offer step-by-step instructions for how to build an automotive engine, a jet plane, or a spacecraft. Instead, they offered something far more valuable: a set of principles that could later be applied to automotive engineering, aeronautics, space travel, and more.
