Level of Learning Theories: String Theory & Loop Quantum Gravity

Click For Summary

Discussion Overview

The discussion revolves around the appropriate educational level at which students begin to learn advanced theories such as String Theory and Loop Quantum Gravity. It explores the prerequisites and considerations for entering these fields within graduate studies, including the necessary background in physics and mathematics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants suggest that foundational theories like Newtonian Dynamics are introduced in the first semester of undergraduate physics, with more advanced topics like Electromagnetic Theory and Quantum Theory typically covered by senior year.
  • There is a belief among some that String Theory and Loop Quantum Gravity are primarily studied at the graduate level, although a few schools may offer introductory courses at the upper undergraduate level.
  • One participant raises the question of whether a student with only minimal physics coursework could still pursue research in String Theory or Quantum Gravity, indicating that such a background might be insufficient.
  • Another participant emphasizes the extensive mathematical background required for these fields, suggesting that a poor foundation in physics would make it challenging to succeed in graduate studies focused on these theories.
  • Concerns are expressed about the likelihood of a student with minimal physics courses being able to work under a professor in these advanced areas, with some arguing that the minimum coursework needed for graduate school is substantial enough to warrant a double major in physics.

Areas of Agreement / Disagreement

Participants generally agree that String Theory and Loop Quantum Gravity are studied at the graduate level, but there is disagreement regarding the sufficiency of minimal physics coursework for pursuing research in these areas. The discussion remains unresolved on the specific prerequisites and chances of success for students with limited backgrounds.

Contextual Notes

Participants note that the minimum physics coursework required for graduate school may not adequately prepare a student for advanced topics in theoretical physics, highlighting the potential need for a more robust background in both physics and mathematics.

At what level (graduate, PhD, etc...) do people start learning theories, such as String Theory and Loop Quantum Gravity?
 
Physics news on Phys.org
Depends what you mean by theories...you start learning Newtonian Dynamic Theory your first semester of undergraduate physics. By senior year of undergraduate, you should have a basic grip on EM Theory, and basic Quantum Theory...as far as String Theory and Quantum Gravity, I don't think you get into these until the graduate level, but I believe some schools have intro courses for these fields available at the upper undergraduate level.

I see...so does that mean that when someone applies for an assistant-ship when applying for a graduate school under the intentions of working in those two fields, they take under consideration an adviser who does research in the particular areas (meaning that you can start work in String Theory or Quantum Gravity at graduate level)?
 
If we're only talking about the two "Theories" you've mentioned, yes this seems to be something first studied at the graduate level, possibly though research under a professor researching this field.
 
I see...now let us say that someone who only did the minimum physics courses (on the basis that physics isn't his/her major) required for graduate school of physics and does relatively well in GRE (this isn't me, this is hypothetical)...what are his chances of working under a professor for these two particular fields (String Theory/Quantum Gravity)?

Those requires a huge amount of maths, quite a lot more than what most maths major takes, in addition to require most of the modern theoretical physics so I guess that it would get really rough if you have a poor background like that.

Those subjects are usually not studied at the masters levels either by the way.

I consider this to be extremely unlikely, unless "minimum physics courses" includes a lot more than most people would consider to be the case.

The minimum amount of physics courses needed for grad school is such that if you were going to take them as electives in order to prepare for the GRE, you might as well just double major in physics.

Four years of undergraduate physics is needed if you want to be prepared for physics grad school.
 
I see...those were well brought answers...thanks.
