Math for physics Definition and 22 Threads

The Journal of Physics A: Mathematical and Theoretical is a peer-reviewed scientific journal published by IOP Publishing. It is part of the Journal of Physics series and covers theoretical physics focusing on sophisticated mathematical and computational techniques. It was established in 1968 from the division of the earlier title, Proceedings of the Physical Society.
The journal is divided into six sections covering: statistical physics; chaotic and complex systems; mathematical physics; quantum mechanics and quantum information theory; classical and quantum field theory; fluid and plasma theory.
The editor in chief is Martin R Evans (University of Edinburgh).

    Courses What math would I need? (physics-math double major interested in THEP)

    So, I am going into my second year in my physics-math double major. For our program, not much specialized math is specifically needed. I love theoretical high energy physics, have been attending seminars in institutes, and been trying to do some reading on my own (it is hard without the math...

    Programs Math minor, double major, and elective classes advice

    There's a lot of questions that float around like "I'm an EE major, should I double/minor in math?", "What math classes should I take as a physics major?", etc. After I typed in the title, this already started to show. Maybe you will disagree with some philosophical points I make, but I think...

    Other What Math Books Are Needed for Self-Taught Physics?

    I am self taught, and would like to know more about physics, and engineering, the biggest issue I have been having is that for most physics courses, and textbooks I read, I do not understand the math behind. My highest math education was calc ab ap in high school. I was wondering if you all...

    What is the electric field due to hollow sphere at R=z?

    So I derived the E-field of a hollow sphere with a surface charge σ at z and I got: E(r)=\hat{z}\frac{\sigma R^2}{2\varepsilon _{0}z^2}\left ( \frac{R+z}{\left | R+z \right |}-\frac{R-z}{\left | R-z \right |} \right ) at z>R, the equation becomes: E(r)=\hat{z}\frac{\sigma R^2}{\varepsilon...

    Does lack of rigour cause problems in Physics?

    Does physics need rigour?My problem lies with the fact that if a physicist makes a mathematical error he may not be able to identify it due to his lack of understanding of the rigourous mechanism which the mathematician is aware of.

    How do I use math to back up my theories in physics?

    Because I'm only in pre-calculus right now (I'm still not in ninth grade yet), I haven't been able to find a way to back up my theories on physics which are mostly based off of reason and logic (I know this is a bad way to back up my theories, I just want to know what you think of them and how I...

    Math Needed for Physics: How Much is Enough?

    From what I understand the math required for physics majors isn't extremely rigorous (except for the most theoretical of branches). I have also gathered from this forum that the reason for this is physicists use math as sort of "tool" and don't study it as a science (this may not be the...
