What Should I Study to Prepare for Theoretical Physics?

Click For Summary

Discussion Overview

The discussion revolves around the preparation needed for pursuing theoretical physics, particularly from the perspective of a junior-level physics student seeking advice on self-study and necessary mathematical foundations. The scope includes theoretical concepts, mathematical methods, and personal experiences in academia.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses a strong preference for theoretical physics over experimental physics and seeks guidance on what to study independently to prepare for graduate school.
  • The participant mentions a lack of adequate mathematical preparation, specifically noting gaps in knowledge regarding differential geometry, topology, analysis, and algebra.
  • Concerns are raised about the quality of available textbooks and resources, with the participant feeling that many do not provide sufficient exercises or practical applications.
  • Another participant shares a link to a resource by Nobel laureate t' Hooft, suggesting it may contain useful advice and links for self-study in theoretical physics.
  • There is a discussion about the unhelpfulness of theorists the participant has approached for advice, raising questions about the expectations of mentorship in academia.
  • A later reply questions the claim that the participant learned nothing in their topology class, prompting clarification that it was an exaggeration and that the class was overly elementary.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to self-study or the adequacy of current educational resources. There is a mix of personal experiences and suggestions, with some disagreement on the effectiveness of the participant's previous coursework.

Contextual Notes

The discussion highlights limitations in the participant's current academic support and resources, as well as the subjective nature of educational experiences in mathematics and physics courses.

Who May Find This Useful

This discussion may be useful for undergraduate physics students considering a focus on theoretical physics, those seeking self-study strategies, and individuals interested in the challenges of academic mentorship in STEM fields.

yes i know there's one right beneath me, and i actually posted in it but my question is a little different than that poster's. I'm actually a physics student at a university at around the junior level and i want to pursue theoretical physics. now i know everyone says this because it sounds so swanky but I've gotten a taste of experimental and i wholly dislike it. anyway after school i'd like to go to industry doing applied math and i figure a theoretical/computational physics background will be the most well rounded where as in applied math i would study just PDEs or SDEs or something like that. plus being a professor some day would be quite enjoyable.

the problem I'm faced with now is that I'm graduating next year tentatively and there's no way i'll be prepared for grad school by then. I'm going to try to push it back another year but barring that there's absolutely no way my classes will prepare me in time. so i'd like to study on my own but I'm having lots of problems.

firstly i have no idea what i should be studying, math wise. I'm halfway through boas' math methods book but i can already tell that will only do exactly what it says, prepare me for undergrad material. there a tiny section on group theory, nothing on differential geometry, nothing on topology etc. secondly most of the books i can grab from the library are , in my opinion, pedagogically flawed. a lot of them are pure math books with no exercises and the ones with proof exercises do not have solutions. i can do proofs but i don't think they teach me how to use tools, only when i can and can't use them. maybe my impression is biased and I'm wrong, I've only done proofs in very elementary classes pure math classes. maybe in the upper level classes you're actually constructing things instead of testing implications.

i just don't know. i would love for someone to give me some advice and what i should be studying and how. note my advisor is an experimentalist, and the theorists I've spoken with have been quite unreceptive. you can consider me at the level of someone who has completed the usual calc sequence, differential eqns and linear algebra and i can write proofs. I'm just finishing a topology class right now but it was terrible and we learned almost nothing. so i haven't had analysis, or algebra, or complex analysis. pdes I'm going to cover on my own within th

I'm just finishing a topology class right now but it was terrible and we learned almost nothing. so i haven't had analysis, or algebra, or complex analysis. pdes I'm going to cover on my own with the month. e month.

honestly, and this is a cry for pity to someone, i feel completely lost and overwhelmed and on the verge of completely failing. i have the desire and even the discipline just no direction.
 
Physics news on Phys.org
Here is a link to a page from Nobel laureate t' Hooft: Some advice for studying theoretical physics on your own and LOTS of links to free online ressources. maybe too much stuff for your current situation - if I understand you correctly, you need direction about where to start, but have a look at it anyway.

EDIT: It's sad that the theorists you talked to have not been receptive, I mean isn't it part of their job to give advice to students ? Perhaps you could tell a bit more about what they said to you, maybe they didn't quite get what you wanted to ask them ?

You learned nothing new in a topology class? That sounds rather amazing.

it was an exaggeration.

no actually its was a hyperbolic for : it was a ridiculously elementary class
