In quantum field theory the “normal ordering” of operators is routinely used, which amounts to
shuffling all creation operators to the left. Potentially confusing is the occurrence in the literature of
normal-ordered functions, sometimes called “Wick transforms.” In this paper, we introduce the
reader to some basic results, ideas, and mathematical subtleties about normal ordering of operators
and functions. The intended audience are instructors of quantum field theory and researchers who
are interested but not specialists in mathematical physics.
