What math is required to "feel comfortable" with physics?

Click For Summary

Discussion Overview

The discussion revolves around the mathematical knowledge required to feel comfortable studying various areas of physics, including classical mechanics, relativity, and quantum mechanics. Participants explore the necessary mathematical tools and concepts that would support a deeper understanding of these subjects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that knowledge of linear algebra, partial differential equations (PDE), and ordinary differential equations (ODE) is essential, noting that additional mathematics may be required based on the level of theoretical engagement.
  • Another participant emphasizes the extensive range of mathematical fields relevant to physics, mentioning that mathematical concepts are often taught in parallel with physics to aid understanding.
  • There is a concern about the subjective nature of feeling "comfortable" with the material, indicating that different individuals may have varying thresholds for comfort based on their mathematical background.
  • One participant questions whether the mentioned mathematical topics would be sufficient for understanding the physics subjects listed, seeking further recommendations.
  • A later reply indicates that the requirements depend on the specific goals and areas of interest within physics.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the specific mathematical requirements for studying physics. There is no consensus on a definitive list of necessary mathematics, as opinions vary based on individual perspectives and intended areas of study.

Contextual Notes

Some participants highlight the variability in mathematical needs depending on the theoretical depth desired and the specific physics topics of interest. There is also an acknowledgment that the understanding of mathematics can be context-dependent.

Who May Find This Useful

This discussion may be useful for students and learners in physics who are assessing their mathematical preparedness for various topics in the field.

Hello everyone. As the title says, what math do I need to know to fully understand classical mechanics, relativity, quantum mechanics... I am studying from a calculus book, but this is mathematics in general it is not focused on physics. So, apart of this calculus book I'm studying from, what math do I need to study physics without fear to find something I couldn't solve? If you could recommend a book on any subject I'd appreciate it. Thanks in advance.

You need linear algebra, Pde, ODE. There are more mathematics that are needed, depending on how theoretical you want to get.

This is quite a long list, a trip through many mathematical fields. For this reason the mathematical part which is needed to understand physics is usually taught in parallel. E.g. Lie groups are important, but physicists don't need to know the entire theory. On the other hand, you said "to feel comfortable in" which is a rather strong condition. The crucial point is, that physicists apply all kind of mathematical tools whenever they promise success, sometimes even those which never have been expected to be useful.

Thanks for the answer. Would this be enough to understand the subjects I named? If there's any other, what would it be?

Depends on what you want to do.
