Hi, I wasn't sure where to post this so I hope it's ok to post my questions here. I would like to learn the basic fundamentals of Loop Quantum Gravity as efficiently as possible. I'm currently 63 years old. I majored in Physics and Chemistry eons ago, and so I'm rusty on everything but can potentially get back parts I need relatively quickly. The main thing I'm looking for is an overview that basically gives the main concepts of Loop Quantum Gravity. Another thing that might also be useful would be a course outline or syllabus intended for students who are interesting in focusing on Loop Quantum Gravity. Some specific questions I have: 1. Are there any good books or lecture videos that are specifically designed to be an "Introduction" to Loop Quantum Gravity. 2. Is a knowledge of String Theory required or helpful in anyway? 3. Do there exist course outlines, or curriculum that is specifically tailored for students wishing to embark on this study. Personal note: I can handle some graduate level materials, but I would really appreciate anything at all that is in the undergraduate realm that would specifically apply to, or be useful for, entering into the study of Loop Quantum Gravity. I'm looking for materials that will give me a good understanding of the basic ideas from which I can then expand from. Final note: I've just finished reading Lee Smolin's book, "Three Roads to Quantum Gravity". I was able to understand many of the ideas he presented. I'm planning on re-reading his book and taking notes this time to try to create my own framework. So that's where I'm at right now. I'm just looking for a way to get best organized to gain a better understanding as efficiently as possible. What I'd like to gain is a "Bird's Eye View" of what it's all about, then I can know better where I need to zoom in and get my hands dirty in the details. All suggestions will be appreciated. Thank you.
