We continue the Introductory series by generalizing the Robertson-Walker metric to describe uniform but non-Euclidean spatial geometries. We introduce the Friedmann equation linking geometry, density and expansion dynamics and discuss the three classic cases of flat, open and closed universes. The original flatness and coincidence puzzles are revisited, and comparison is drawn between 20th and 21st century views of cosmology.
