String topology is concerned with a certain multiplicative structure existing on the chains on the free loop space of a manifold. I'll explain how approaching this structure from three rather different points of view, one algebraic, one geometric and one inspired by physics, all lead to considering the same compactification of the moduli space of Riemann surfaces.
