Query: What hath Weinberg wrought? Reflections on what Weinberg's papers on
  'Nuclear Forces from Chiral Lagrangians' did and did not accomplish   I discuss selected legacies of Weinberg's application of chiral Lagrangians
to nuclear physics: (1) the use of the chiral expansion to organize the
interaction of pions and photons with a nucleus; (2) the much-debated question
of why and how the potential derived from a chiral Lagrangian should be
inserted in the Schrodinger equation; (3) the emergence of "pionless EFT" as a
tool for diagnosing universal correlations that are present in quantum few-body
systems of very different sizes, and, perhaps most important of all, (4) an
epistemological shift in what is expected of a nuclear-physics calculation.
