I'm looking for less of a recommendation on resources for a specific topic, and more for a general path of what to learn to get to a certain topic. If there's a better place to ask this or tag to use, let me know - I couldn't think of anything better.

I want to learn about the holographic principle and related concepts, in all its mathematical rigor. Now, before I am ridiculed on how large a task this is, I admit - it's probably unfeasible. But the value is in the journey; even if I don't make it that far, I'd love to know plenty of stuff on the way.

Problem is, I have no clue how to tackle it. Where I'm currently at, I know a decent bit of undergraduate mathematics and physics, and I have a vague idea that learning GR might be a good step. But ideally, I really need a path forward, what topics to learn to get from here to there.

Once again, if I'm asking in the wrong place, let me know if you know a better one.

  • $\begingroup$ @anna v Ah, I meant this holographic principle. PBS SpaceTime on YouTube recently did a video on it, which (among other predispositions) made me want to learn the intricacies of it. $\endgroup$ – Vedvart1 Apr 12 at 6:13
  • $\begingroup$ Learning GR and it's core mathematics would strike me as a fundamental step and I'd start with that - it's a big task itself. $\endgroup$ – StephenG Apr 12 at 6:19
  • $\begingroup$ @StephenG Any recommendations for after that? I like to have the concepts of future topics to learn floating around, so I can try to think about possible connections for the future along with linking my current learning to a bigger picture. $\endgroup$ – Vedvart1 Apr 12 at 6:21

    $\begingroup$ "After that" could be a few years down the road (GR is pretty hard work for most people, especially with mathematical rigor) and by them your interests could (probably will) have shifted. I would not plan on that time scale and suggest exploring physics from GR and QM/QFT and seeing where it naturally leads you. $\endgroup$ – StephenG Apr 12 at 6:24

The only known examples of the holographic principle are AdS/CFT pairs, so that implies you need to learn string theory and supersymmetric conformal field theory. But you could also read the papers by 't Hooft and Susskind which preceded Maldacena's AdS/CFT, as they motivated the concept.
