Imagine the Universe is a periodic crystal. If gravity makes space negatively curved, the thin walls of the crystalline structure might trace out a pattern of circles in the sky, visible at night. In this talk we will describe how to generate pictures of these patterns and how to think like a hyperbolic astronomer. The […]
Curtis T. McMullen works on hyperbolic geometry, at the horizon where visualization both prompts and gives way to the imagination. He received the Fields Medal for his research on complex dynamics and 3-manifolds, and is currently a professor of mathematics at Harvard University.
