Mathematical Principles of Natural Philosophy and His System of the World: The System of the World - Isaac Newton - Hardcover

I consider philosophy rather than arts and write not concerning manual but natural powers, and consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore I offer this work as the mathematical principles of philosophy.In the third book I give an example of this in the explication of the System of the World. I derive from celestial phenomena the forces of gravity with which bodies tend to the sun and other planets.Newton, Isaac is the author of 'Mathematical Principles of Natural Philosophy and His System of the World: The System of the World - Isaac Newton - Hardcover' with ISBN 9780520009271 and ISBN 0520009274.
