We explain the physical meaning of some recent results in category theory: Associated to any topological quantum field theory (in the sense of a functor) is a quasiquantum group of internal symmetries. Associated to any algebraic quantum field theory (where there is no functor) is a braided group. We also mention some joint work relating Chern-Simons theory to quantum mechanics in a bounded domain.
