At Perimeter Institute, Bianca Dittrich recently gave a survey introduction to (non-string) QG with Lee Smolin and Leonard Susskind asking questions among other.
The talk video is online PIRSA 07120030
and the title was Introduction to Quantum Gravity
I think of this as a kind of QG map from the Perimeter perspective. It looks like there was a big audience, as P.I. seminars go. She was laying out the whole field, including the history from the 1930s on. Giving an overview of 70 years of QG, and the present, and HIGHLIGHTING THE MOST SALIENT APPROACHES as she saw them.
So it's interesting what she did and did not mention and what she emphasized by spending time on.
0-12 minutes history and general ideas
12-20 eight minutes on Triangulations (CDT) approach. She herself is not working in this but according to her two other people at P.I. are----Joe Henson and Dario Benedetti.
It was remarkable that she put it first and devoted so much time. It is a good intro to basic CDT.
20-28 canonical LQG+Spinfoam+Loop Cosmology. Eight minutes on that whole line of research, which is what she is working in herself.
28-32 four minutes on efforts to derive the low energy limit and testable predictions
(passing mention of several other approaches but no details on them.)
32+ Open questions. Summary of conclusions. Discussion from the audience.
