Inertia:
“Inertia is dynamic–as sensed in the orbital course integrity of the enormous mass of Earth going around the Sun at 60,000 m.p.h., so that the little man on board it, who is also going around the Sun at 60,000 m.p.h., and is also walking around Earth at four m.p.h. and as he steps around Earth’s surface he pushes the Earth in the opposite direction to his walking, but so negligibly that the little man does not conceive of his Earth as movable and so has invented the concept of completely inert, or ‘at rest.’ Our deceptive fixity of celestial position as a standing still in Universe is forgotten by the absolute silence of travel in vacuo around the Sun.”
