Query: Dimensional Power Counting in Nuclei   Weinberg's dimensional power counting for nuclei is reprised in this primer.
The role of QCD and chiral symmetry in constructing effective Lagrangians is
discussed. The two-scale hypothesis of Manohar and Georgi is combined with
power counting in amplitudes to shed light on the scales of nuclear kinetic and
potential energies, the size of strong-interaction coupling constants, the size
of meson-exchange currents, and the relative sizes of $N$-nucleon forces.
Numerous examples are worked out and compared to conventional nuclear models.
