Quantum Looking for a good String Theory text

AI Thread Summary
The discussion centers on the challenges of self-studying String Theory, particularly the difficulties encountered with Becker, Becker, and Schwarz's "String Theory and M-Theory." The initial chapters are criticized for lacking clear physical reasoning and assuming prior knowledge that the learner does not possess. The participant expresses the need for a more accessible resource and outlines specific areas for review, including advanced group theory, conformal field theory, supersymmetry, Lie algebra, topology, and E8. Suggestions for alternative texts include Kaku's book and Zwiebach's "A First Course in String Theory," which appears to be a promising option. Additionally, Peter West's textbook is recommended for its clarity and depth.

(Sorry about writing a book! But I felt more information was the better mistake.)

Okay, here's the deal. I have been teaching myself Physics and Math beyond my MS in QFT. I have been doing this for the last 20 or so years and I've gotten reasonably decent at it but String Theory is a bit beyond what I'm used to tackling. (I will pass over why I don't have a PhD. It's personal.) I have Becker, Becker, and Schwarz's "String Theory and M-Theory" text and have reluctantly decided that I need a source better suited to me. I was looking at it again over the last several months and concluded that the first three chapters (bosonic field theory) is a bit of a mess to learn from. There does not seem to be any real Physical reasoning behind the methodology, which spans from showing as basic as a sketch of how to contour integrate over a pole on a path to vague comments that make it sound like I already need to know everything about the Virasoro Algebra. If I already knew the theory and was working on a review it would be fine. But it's tough to learn from. The good news is that once we get to Chapter 4 and fermionic field ST the text settles down. But I need the results of the first three chapters to understand the methods.

So. What I know I need to review:
1) Basic group theory beyond the usual 4 space-time dimensions. Should I do SR in more than 4 as well?

2) I have a rough handle on conformal field theory but another review wouldn't hurt.

3) Same for SuperSymmetry.

4) I guess I need to go over more Lie Algebra theory. But once I get past Chapter 3 it seems to settle out and I only need the basics again? I couldn't see much mention beyond bosonic field theory.

5) I've got Intro Topology but I'm clearly going to need something deeper. I'm going to ask some Math friends about it but a Physics oriented text suggestion would be appreciated.

6) I need information on E8. Nothing in my reference library contains any mention of it. The Wikipedia article is nice but it doesn't show say anything about why we should use it. E8 is alien to me right now and I need another source.

I have been sporadically looking for another ST text for the past several years. I have decided that Kaku's text might be a good move. Any thoughts or other suggestions?

Thanks!

For a readable introduction to string theory I recommend Zwiebach, A First Course in String Theory.

Yes, I encountered that one on my search. I'll look into it. Thanks!

Okay. It looks like it covers everything I am (at least currently) interested in. I'm going to jump on it. Thanks again!

I strongly recommend Peter West's textbook. Very clear explanations and goes quite deep into the subject covering modern material.
 
The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...
I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
