To start with our own movements mean the most. Then we find ourselves among the movements of all others. In ancient Mesopotamia activities to clear the Persian gulf delta marshes prepare the ways for canal irrigation. Ancient Egyptians move megalithic blocks up towards the stars in pyramids and temples.
Transport of materials along the Nile and across the Mediterranean provides early sense of the efforts needed to move bulk freight. In motion themselves with stars for guidance an early skilful practice of mass handling develops. Peoples of these coasts become adept at clearing waterways for canal building. Moving rock masses they construct aqueducts and are able to divert water over uneven terrain.
African Arabian travelling scholars bring knowledge from the ancient world to Renaissance Europe. Here Galileo experiments with rolling balls down inclined planes to find that acceleration to the earth is really energy change. Isaac Newton learns about inertia and momentum and deepens comprehension of mass and motion. In universal gravitation a description of how to access energy changes of all masses and motions is attained.
Our activities enable us to access all energy interchanges. Mass is a means to identify motions of objects. In reality we are in among all these exchanges and we have sets of operations to effect required motions. With mass as an energies interchange function of the whole universe we can successfully complete any venture.
