Abstract: The dichotomy of the pion as QCD's Goldstone mode and a bound state of massive constituents is easily understood using the Dyson-Schwinger equations. That provides the foundation for an efficacious phenomenology, which correlates the pion's charge radius and electromagnetic form factor with its valence quark distribution function; and simultaneously provides a Poincare' covariant description of the nucleon, its form factors and, more recently, meson photoproduction processes. This well-constrained framework can also be used to eliminate candidates for an extension of the Standard Model by providing the relation between current-quark electric dipole moments and that of the neutron
