Strange metals are conducting states of quantum matter without any quasiparticle excitations. The copper-based high temperature superconductors display a strange metal at temperatures above the critical temperature, Tc, for superconductivity, and at electron densities where Tc is maximal. I will describe a solvable model of a strange metal whose properties match quantitatively with those of charged black holes. Then I will outline a general framework for computing observable properties of strange metals, drawing upon numerous theoretical methods, including the black hole mapping. Finally, I will describe a recent experiment in graphene, in which theory is compared with a (slightly less) strange metal.
