Title: An introduction to cohomology

Abstract:  Although at first the standard definitions of cohomology may 
seem very strange, I will show how cochain complexes and cohomology 
arise naturally from the seemingly-trivial study of locally constant 
functions on smooth manifolds.  As applications, we will see that a 
manifold cannot retract to its boundary, and that there is no 
orientation-reversing diffeomorphism of CP^2.
