Gravity as central to the form and evolution of the universe. Conceptual formulation of gravity from the Renaissance to Einstein. Its consequences from the falling of an apple to the slowing of the expansion of the universe.
Class description
We will start with our own observations of the night sky and relate those to the theories of Ptolemy and others, reproducing and understanding the universe from a geocentric point of view. We then move to Galileo's and Newton's time periods and the definition of gravity. We investigate the steps that led to the acceptance of the heliocentric universe, and then a universe with no center. We investigate large scale structure, the expansion and possible acceleration of the universe, and such ideas as superstrings.
