Math Needed to Study Physics of Loop QG, ST, QED/CD & GR

Click For Summary

Discussion Overview

The discussion revolves around the types of mathematics necessary for studying various advanced physics topics, including loop quantum gravity, string theory, quantum electrodynamics/chromodynamics, and general relativity, particularly at a basic level.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that a comprehensive understanding of all types of math is necessary.
  • Another participant argues that for a basic level, number theory is not required and recommends reviewing elementary textbooks to identify needed mathematical concepts.
  • Specific textbooks are mentioned as resources for different subjects, including Griffiths for particle physics and Zwiebach for string theory.
  • It is noted that a strong understanding of general relativity and quantum field theory may be essential even for elementary studies in loop quantum gravity.
  • Calculus and differential equations are highlighted as foundational mathematical areas.
  • A participant inquires about the existing mathematical knowledge of another, indicating that prior knowledge may influence the required math for these physics topics.
  • One participant shares their background in mathematics, mentioning derivatives, integrals, differential equations, complex numbers, and basic linear algebra, while noting gaps in knowledge regarding rings and fields.

Areas of Agreement / Disagreement

Participants express differing views on the extent of mathematical knowledge required, with some advocating for a broad understanding while others suggest a more focused approach based on existing knowledge.

Contextual Notes

There is uncertainty regarding the equivalence of mathematical education across different countries, which may affect the participants' assessments of their own knowledge and the math needed for physics.

Hi! This is a question for the physicists. What types of math do I need to study the physics of ... let's say loop quantum gravity, string theory, quantum electro dynamics/ chromodynamics and general relativity on the basic level?

Tnx

All of it.
 
Notice he's asking on a basic level. At least number theory is not required on a basic level.

My advice would be to pick up elementary textbooks on each of these subjects and skim through them to see what you need. In some cases, the math you need will be covered in the book itself.

For instance, check out Griffiths for particle physics, Zwiebach for string theory, for quantum field theory, I don't know what the most basic text is, for general relativity, there are many choices, two that come to mind are Carroll and Schutz. Loop quantum gravity is less popular a theory, so I doubt there is an elementary text about that. I suspect a strong understanding of general relativity and quantum field theory is required for even the most elementary study.
 
The foundation is calculus, and then differential equations.

It's hard to compare the swedish math education to the american. I don't know how much calculus I know for instance compared to what year of college/ high school in US. But derivatives, integrals, differential equation, complex numbers (don't know if what i read qualifies as complex analysis), very basic linear algebra, three-variable calculus... Stuff like that. I don't, for instance, know what rings and fields are.
