Discussion Overview

The discussion centers around the mathematical prerequisites necessary for understanding General Relativity (GR), Special Relativity (SR), and Quantum Mechanics (QM). Participants share recommendations for textbooks and express varying opinions on the necessity of certain mathematical topics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant seeks recommendations for textbooks to self-study mathematics and physics relevant to GR, SR, and QM.
  • Another participant lists a sequence of advanced mathematics textbooks, including Linear Algebra, Measure Theory, and Functional Analysis, as foundational for these topics.
  • Some participants question the necessity of Measure Theory and Functional Analysis for QM, suggesting that basic Hilbert space theory suffices for most students.
  • It is mentioned that an introductory QM class typically requires only Calculus I-III and differential equations, with additional topics like probability and linear algebra being beneficial.
  • One participant suggests that a solid understanding of linear algebra and multivariable calculus is sufficient to approach Schutz's "A First Course in General Relativity."
  • Another participant emphasizes the importance of matrix algebra and Fourier analysis for QM, along with exposure to Hamiltonian mechanics.
  • Several participants recommend starting with physics-focused books that integrate the necessary mathematics, such as Taylor & Wheeler's "Spacetime Physics" and Eisberg & Resnick's "Quantum Physics of Atoms, Molecules, Solids, Nuclei, and Particles."

Areas of Agreement / Disagreement

Participants express differing views on the necessity of advanced mathematical topics like Measure Theory and Functional Analysis for QM, indicating a lack of consensus on the prerequisites for understanding GR, SR, and QM.

Contextual Notes

Some participants note that the discussion may depend on the specific focus of the courses or texts being considered, as well as individual backgrounds in mathematics and physics.

I'm sure this has been posted before, but I did a quick search and couldn't spot anything.
I was wondering what textbooks I might be able to self-study in order to get up to speed in mathematics and physics so that I might be able to understand GR, SR, and QM.
Currently I'm up to speed on basic Calculus and a semester of physics but I want to study on ahead. I suppose the textbooks for introduction into GR, SR, and QM would not be necessary since it would take me a while to work up to them.

Can anyone recommend some good books that would cover the necessary material for a solid understanding? Thank you!

Thank you very much! I appreciate it.

I don't understand why everyone has the urge to list Measure Theory and Functional Analysis as a prerequisite to QM. Unless you're doing some hardcore mathematical quantum mechanics course, which I would estimate 99% of QM students/practitioners haven't taken, the only thing you'll need and use is some basic Hilbert space theory. You don't need to take Differential Geometry to be able to integrate in polar coordinates.
 
you need to study tensor calculus and and ODE/PDE. These are the more applied courses you can study.

Functional analysis would be nice to study as well
 
An introductory QM class would require just Calc I-III and differential equations.

The probability, linear algebra, PDE (mostly seperable), Fourier theory can be picked up. If you use Griffiths book for QM he goes over the mathematics well enough to understand the concepts.
 
If you have some good linear algebra and multivariable calculus you can probably tackle Schutz's A First Course in General Relativity

Your 15 and have gone through these !?

I am in the same level as the OP. I am starting with linear algebra.

I think Pinu7 was "taking the piss" as the Brits say.

Trig is enough for basic SR.

For QM, I suggest taking a look through Shankar to get an idea of the math involved. It helps to be strong in matrix algebra and Fourier analysis. Exposure to Hamiltonian mechanics is also helpful.

Most GR books develop the needed math. It helps to be strong in multi-variate calculus.

Physics background: The Feynman Lectures, Volumes 1 & 2.

I would start with some books that emphasize physics over math:

Taylor & Wheeler: Spacetime Physics and Exploring Black Holes
Eisberg & Resnick: Quantum Physics of Atoms, Molecules, Solids, Nuclei, and Particles
