  This is the second in a series of papers intended to provide a basic overview
of some of the major ideas in particle physics. Part I [arXiv:0810.3328] was
primarily an algebraic exposition of gauge theories. We developed the group
theoretic tools needed to understand the basic construction of gauge theory, as
well as the physical concepts and tools to understand the structure of the
Standard Model of Particle Physics as a gauge theory.
  In this paper (and the paper to follow), we continue our emphasis on gauge
theories, but we do so with a more geometrical approach. We will conclude this
paper with a brief discussion of general relativity, and save more advanced
topics (including fibre bundles, characteristic classes, etc.) for the next
paper in the series.
  We wish to reiterate that these notes are not intended to be a comprehensive
introduction to any of the ideas contained in them. Their purpose is to
introduce the "forest" rather than the "trees". The primary emphasis is on the
algebraic/geometric/mathematical underpinnings rather than the
calculational/phenomenological details. The topics were chosen according to the
authors' preferences and agenda.
  These notes are intended for a student who has completed the standard
undergraduate physics and mathematics courses, as well as the material
contained in the first paper in this series. Having studied the material in the
"Further Reading" sections of would be ideal, but the material in this series
of papers is intended to be self-contained, and familiarity with the first
paper will suffice.
