Discussion Overview

The discussion revolves around the question of whether a self-taught physics learner should focus on studying physics textbooks to learn the necessary mathematics or if they should also engage with specialized mathematics textbooks. The scope includes considerations for both undergraduate and graduate levels of study.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant has mastered various areas of mathematics and is currently studying waves and oscillations, questioning the best approach to further learning.
  • Some participants suggest that with a solid foundation in mathematics, it may be more beneficial to learn math through physics textbooks, viewing math as a tool for understanding physics.
  • Others caution that while learning math through physics is generally advisable, there may be instances where specialized math textbooks are necessary for a deeper understanding of certain concepts.
  • There is a suggestion that the approach to learning math may not differ significantly between undergraduate and graduate levels, emphasizing the importance of context in applying mathematical concepts to physics.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of specialized math textbooks versus learning math through physics. There is no clear consensus on the best approach, indicating that multiple competing views remain.

Contextual Notes

Participants note the potential difficulty in relating material from specialized math textbooks to its application in physics, highlighting a limitation in the approach of learning math strictly from those sources.

Who May Find This Useful

This discussion may be useful for self-taught learners in physics, educators considering curriculum design, and individuals interested in the relationship between mathematics and physics education.

I managed to master the single variable, multivariable, and vector calculus, linear algebra, and some ordinary differential equations. After that, I studied advanced advanced introductions to classical mechanics and electrodynamics. I'm currently studying waves and oscillations and don't intend to stop somewhere. My question then is whether from now I should only study the physics textbooks and learn the math I need through physics, or learn math from specialized math textbooks.
Is the answer the same for both undergraduate and graduate level books?

In general, now you have all the basics, this is probably the better approach.

Only now and again if it's something you need to nail down thoroughly. Note, however, that it's often difficult to relate the material in specialized maths books (e.g. Lie Groups and Lie Algebras) to the application of that mathematics to physics.

If your primary interest is physics, then you should view math as a tool for physics. Learn the math you need from physics books, supplemented by books geared towards "math for physicists (scientists, engineers)" rather than books geared towards math for mathematicians. This holds for undergrad and grad.
