Query: Neutrino Physics Without Oscillations   There is a tremendous potential for neutrinos to yield valuable new
information about strongly interacting systems. Here we provide a taste of this
potential, beginning with the existence of a rigorous sum rule for the proton
and neutron spin structure functions based on the measurement of the flavor
singlet axial charge of the nucleon. We also comment on the NuTeV report of a
3$\sigma$ deviation of the value of $\sin^2 \theta_W$ measured in neutrino (and
anti-neutrino) scattering from that expected within the Standard Model.
