Abstract
Certain abstract constructs in ordinary four-dimensional Physics are found to acquire simple geometrical interpretations in the context of Kaluza reduction from higher dimensions. Among such constructs we treat the operation of charge conjugation, the (abelian or non-abelian) Lorentz force, and the forces on point particles moving in the scalar fields of a GL(N, R)/O(N, R) σ-model. Some cosmological and “experimental” aspects of dimensional reduction are discussed.
