  Several topics in QCD are reviewed, including: the light-cone Fock state
representation, which encodes the flavor, spin and other quark and gluon
correlations of hadrons in the form of universal process-independent
amplitudes; the light-cone factorization scheme for inclusive and exclusive
processes; the application of the light-cone formalism to semi-leptonic B decay
amplitudes; self-resolving diffractive interactions as a tool for measuring
light-cone wavefunctions; and the use of conformal symmetry as a template for
QCD predictions, such as commensurate scale relations, which relate observable
to observable at fixed relative scale without renormalization scale or scheme
ambiguities.
