Lattice Fields and Extra Dimensions

Abstract

Lattice gauge theory is now well into its third decade as a major subfield of theoretical particle physics. I open these lattice sessions with a brief review of the motivations for this formulation of quantum field theory. I then comment on the recent drive of lattice theorists to include a fictitious ``fifth'' dimension to treat issues of chiral symmetry and anomalies.
