Great men, great ideas; from fall to float; interval - revelation that all of space is ours; boomerang through the Earth; tides - the grip of mass on spacetime; momenergy - the grip of spacetime on mass; the boundary of a boundary - where the action is; from potter's wheel to space geometry; picturing space and spacetime around a centre of mass; stones in flight and planets in orbit; gravity waves; black holes; a farewell look at gravity.
