In quantum field theory, states with large quantum numbers under the conserved charges of the theory are generically amenable to a semiclassical description. This observation underlies some recent progress in the study of the spectrum of operators with large internal charge in strongly coupled conformal field theories. I will review these results and show how similar ideas can be used to overcome the breakdown of perturbation theory for multi-legged amplitudes in the epsilon expansion.
