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 Schrödinger equation; (3) the emergence of "pion less 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.
