Some conceptual issues of quantum gravity

We shall attempt to give a non-rigorous and informal review about the implications of combining general relativity and quantum mechanics. The main focus will be on two topics, the Problem of Time and the Black-Hole Information Paradox, and their implications on the structure of both QM and GR. Some other relevant issues will also be mentioned, like quantum cosmology and the Measurement Problem. The goal of the lecture is to emphasize the main "points of friction" between GR and QM, and to illuminate why the gravity quantization program is nontrivial.
