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.

These are introductory lecture notes on complex geometry, Calabi-Yau manifolds and toric geometry. We first define basic concepts of complex and Kahler geometry. We then proceed with an analysis of various definitions of Calabi-Yau manifolds.

These notes are based on a set of six lectures that the author gave in Edinburgh and they cover some topics in the interface between Geometry and Physics. They involve some unsolved problems and they may stimulate readers to investigate them.

In this essay we wish to embark on the telling of a story which, almost certainly, stands only at its beginning. We shall discuss the links and the interaction between one very old subject, physics, and a much newer one, topology.
