A quantum field theory is topological when its amplitudes only depend on the diffeomorphism class of the spacetime manifolds. It has long been conjectured, and recently proved, that 3-dimensional topological quantum field theories are exactly classified by theories of interacting anyons. The proof is satisfying, and I will show how it works, in particular showing how it gives a powerful new way to understand particle-field duality for these theories. This talk will develop these ideas in an elementary way and no previous knowledge of topological field theories will be required. (Based on B. Bartlett, C. Douglas, C. Schommer-Pries and J.
