Isaac Newton once wrote to Edmond Halley that the theory of the motions of the Moon made his headache and kept him awake so often that he would think of it no more. What gave him such a great headache? We look at the motions of the Moon and the underlying perturbations that never exactly repeat. There is the familiar cycle of the Moon phases, the draconic cycle of repeating eclipses, the anomalistic cycle of super moons and the lunar libration that allow us to glimpse features on the far side of the Moon, the side that is turned away from us. We know the Moon "pulls" on the tides but why are the tides in the Southern Australian coast more governed by the Sun? In this one-night course we will explore these characteristics of the Moon in the classroom and with visualisations in the planetarium.
