One hundred and forty seven years after Edwin Hall's discovery of the classic effect in which an electric potential difference is generated across an electric current, different versions of the Hall effect continue to fascinate and are at the very heart of contemporary theories of electronic transport. The anomalous Hall effect, the spin Hall effect, and the orbital/valley Hall effect in their classical and quantum realizations have forced us to reconsider long-held distinctions between conductors and insulators, ushering a conceptual revolution in solid state theory. This talk tells the story of this revolution including the most recent discoveries concerning the role of quantum geometry in the nonlinear Hall effect in normal metals and superconductors.
