Popis: This article, written to honor Brian Josephson on the occasion of his 80th birthday, discusses the topological nature of an emergent collective variable, namely the gauge-invariant phase difference across the two leads of a superconducting tunnel junction, which plays a central role in Josephson’s discovery of the effect bearing his name.
