The Geometrization of Physics by Richard S. Palais
Publisher: University of California at Irvine 1981
Number of pages: 107
The major goal of these notes is to develop, in sufficient detail to be convincing, an observation that basically goes back to Kaluza and Klein in the early 1920's that not only can gauge fields of the "Yang-Mills" type be unified with the remarkable successful Einstein model of gravitation in a beautiful, simple, and natural manner, but also that when this unification is made they, like gravitational field, disappear as forces and are described by pure geometry, in the sense that particles simply move along geodesics of an appropriate Riemannian geometry.
