Zakopane lectures on loop gravity

These are introductory lectures on loop quantum gravity. The theory is presented in self-contained form, without emphasis on its derivation from classical general relativity. Dynamics is given in the covariant form. Some applications are described.Comment: This is a largely restructured and expanded version of the lectures. In particular, I have added a substantial introductory and orientation Section, a discussion on the justification for the vertex expansion, and more details on the applications. Comments and corrections always very welcome. 34 pages. Many figure
