In 1543 Copernicus wrote 'On the Revolutions of the Celestial Spheres' and the Aristotelian world started to come unglued. Falling bodies and inertia were understood but there was no unifying principle. And then, in one breathtaking book, Isaac Newton invented physics as we know it today and restored order to the heavens and the earth. Force equals mass times acceleration. It is the heart of classical mechanics. This gripping production demonstrates how Newton refined Galileo's law of inertia, and developed his first and second laws of classical mechanics.
