Recently a new formulation for supergravity has emerged inspired by the presence of duality symmetries in reduced theories. These new theories generalise ideas of Riemannian geometry and lead to new ways of looking at string and M-theory.

We reformulate M-theory in a duality manifest way using generalised geometry.

This is an introduction to Gerbes aimed at physicists. The approach will be to introduce Cech cohmology and its relation to gauge theories, monopoles and Wilson loops and then give the extension to extend these ideas to the relation between higher order Cech cohomolgy, gerbes and strings.
