Talk Title:
The Unexpected Universe: Astronomical Telescopes Continue to Reveal New Surprises

Talk Abstract:
Cosmology in recent decades has been undergoing a revolution. Astronomers have for the first time identified the major constituents of the universe, revealing a universe that hardly resembles what we thought only a few decades ago. It is filled with dark matter that is not visible and energy that permeates all of space, causing its expansion to speed up with time. Thousands of planets are now being discovered beyond our Solar System. New giant telescopes planned for the next decade are likely to reveal more surprises. In her lecture, Professor Freedman will describe these exciting advances.

Talk Title
Poincaré's Legacy: Predictions on Time Scales Ranging from Milliseconds to Billions of Years

Abstract
I will discuss and connect two long-standing, and at first glance entirely unrelated, problems of prediction: (1) the long-term dynamical stability of the Solar System, and (2) price movements and volatility in financial markets. These phenomena have radically different governing mechanisms, and their characteristic time scales are vastly different, but they share a key common basis in the random walk, and the study of both can be traced directly back to the work of Henri Poincaré.
