  We show that two dimensional QCD can, to a good approximation, describe the
hadronic structure functions measured in Deep Inelastic Scattering. We
transform this theory into a new form, Quantum HadronDynamics (QHD), whose
semi-classical approximation is closer to nature. The Baryon is then a
topological soliton, and its structure function can be predicted by a
variational principle. This prediction can be tested by comparison with
measurements of neutrino scattering cross-sections.
