Surprises abound when strong magnetic fields are imposed on two‐dimensional electron gases at low temperature. When the electron density approaches an integral multiple ν of the density of magnetic flux quanta threading the plane, the resistivity of the electron system begins to vanish and its Hall resistance takes on the quantized value
