A great deal of fundamental mathematics has been directed at the question of "hearing the shape of a drum," or reading geometric features of a plane domain or manifold off from its Laplace spectrum. I'll address a parallel question in symbolic dynamics: if you have a Euclidean polygon and only know the sequences of sides struck in succession by billiard trajectories—that is, the bounce spectrum—does it determine the polygon? Spoiler: The answer is basically yes. This is joint work with Erlandsson, Leininger, and Sadanand.
