Publisher's Synopsis
Excerpt from The Elementary Principles of Mechanics, Vol. 1: Kinematics
Thus we recognize matter in certain states which we call solid, liquid or gaseous. We distinguish also different kinds of matter, such as iron, wood, glass, water, air, etc., which we call substances. We also recognize limited portions of matter of definite shape and volume, such as a pebble, a rain - drop, a planet, etc., which we call material bodies. But what matter is in itself we do not know.
