How are David Tong's Lectures on General Relativity?

Click For Summary

Discussion Overview

The discussion revolves around the effectiveness of David Tong's lectures on General Relativity (GR) for learners, particularly in relation to prior knowledge and alternative resources. Participants share their experiences and challenges with the material, as well as their plans for studying GR.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses confidence in David Tong's notes on Quantum Field Theory (QFT) but struggles with the introduction to differential geometry in Tong's GR lectures, particularly with concepts like Lie derivatives.
  • Another participant questions the learner's rapid progression from special relativity (SR) to GR, suggesting that the transition may be too abrupt given their previous inquiries about basic SR concepts.
  • A participant mentions learning SR from Griffiths' "Introduction to Electrodynamics" and expresses uncertainty about whether this background is sufficient for tackling GR.
  • Concerns are raised about the high level of abstraction in Tong's lectures, with a suggestion that Sean Carroll's approach may be more accessible for beginners.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the suitability of Tong's lectures for beginners. There are differing opinions on the adequacy of prior knowledge and the effectiveness of alternative resources like Carroll's book.

Contextual Notes

Participants express uncertainty regarding the prerequisites for understanding GR and the appropriateness of different teaching styles. There is no agreement on the best approach to learning GR based on individual backgrounds.

Hi. I have tried David Tong's note on QFT. I think it works well for me and lead me into QFT. Now I am confident to read Peskin's book.

Now I am trying to learning GR. I planned to try David Tong's lectures on GR first and then read Sean Carroll's book. But I am not sure this plan now. I got lost in chapter 2, introducint differential geometry, in David Tong's lectures. It throws a lot of concepts I have never seen without sufficient examples, especially topics about Lie derivatives.

If you are familiar with Tong's notes, could you give me some advice that should I try other's notes, or just start with Sean Carroll's book?

Thanks!

I have not heard Tong, but I do know that seven months ago you were asking the most basic questions on SR. It is highly unlikely that you've progressed from there to studying GR on your own in that short a time.

Hi, @Vanadium 50 . I learned SR from Introduction to Electrodynamics by Griffiths. I am not sure whether that is sufficient or not. But I think I can understand the main concepts of SR when I read books about QFT and papers about relativistic quantum optics.

I am going to be a graduate student two weeks later. Since my research area would include quantum optics in curved spacetimes, then I am going to take a GR course. Thus I wish to learn it before I take the course.
 
I'm not going to argue with you. On the one hand, you claim you can whip through SR with enough comprehension. On the other, you say you don't understand GR lectures.

Looking at my copy of Griffiths, I don't think that it is near enough preparation for a GR course and before you ask, I don't have anything handy to suggest.

Tong introduces those concepts on a rather high level of abstraction, much higher than necessary for a first course in GR. Carroll is more down to Earth on this.
