Question: Who introduced a map that was used by a Nobel Prize winning physicist to work out the theory of quantum angular momentum?
Sentence (from "Jordan map"): It was introduced by Pascual Jordan in 1935 and was utilized by Julian Schwinger in 1952 to re-work out the theory of quantum angular momentum efficiently, given that map’s ease of organizing the (symmetric) representations of su(2) in Fock space.
Relevant evidence: Yes
