I'm interested in focusing on nonlinear dynamics or mathematical physics for my PhD and was wondering if anyone could tell me what US universities have strong departments in these topics. I've heard that Cornell is good for dynamics and chaos but haven't heard much about other colleges. Thanks.

I don't really understand the difference between the two. Can someone please highlight the differences and resemblances? Thank you in advance.

hi, i'm wanting to start a degree next year in either physics or mathematical physics. The mathematical physics degree is a joint honours degree. I'm just wondering what is the difference between physics and mathematical physics? Is mathematical physics basically just another name for...

I am applying for undergraduate schools in Canada at the moment, and most of them have provided me the option of taking several specialized programs with a focus on physics. They have programs like computational physics, astrophysics, chemical physics, mathematical physics and, of course...

I'm reading Schutz's text Geometrical methods of mathematical physics right now as a part of a diredcted study (Two of my former math professors and I wish to learn the subject together so we formed a group for self-study). I know the material in a general sense but not at the precision of this...

Hi all I'm currently self-studying a relatively new book, "A Course in Modern Mathematical Physics", by Peter Szekeres, retired fellow at Uni of Adelaide (yes, he's the son of George Szekeres, of "Kruskal-Szekeres coordinates" fame :wink: ). I find it so far to be a totally great book! I...

I tried to read Classical Electrodynamics - 3rd Ed by J.D. Jackson cover to cover with the aim of working through all the homework problems. Problem: The math is too prohibitive. I need to drop that book for now and pick up a book on mathematical physics and go through that first. I'd like some...

So I'm taking a class that's actually called techniques of theoretical physics. Basically, its applying math to physics. Topics we cover are: Vector Calc, Diff EQ, Linear Alg, and Fourier series, (i think, that's from memory.) problem is, the professor is insanely fast, the material is hard, and...

I will shortly be going to edinburgh university to study either physics or mathematical physics. The main difference is that all of the experimental lab work would be replaced by specialist mathematical physics stuff. Do they have similar job prospects or is there more work in one field than the...

I'm thinking of studying mathematical physics at my local university. But I'm no sure what kind of a job I could get with such a degree,. I'm interested mostly in scientific reasrch and stuf like that. I'm not really a major fan of industial reassrsh. So could somen pleas tell me what a...

Is mathematical physics the study of physics that is focused on the mathematics? If it is, would it give me a disadvantage in the field theoretical physics for choosing mathematical physics instead of mathematics in the future?

I am a student in physics engineering and I recently heard about a book called "Mathematical Physics" written by Eugene Butkov. I would like to know if there is a free electronic version (like .pdf) of this book over the Internet because the book itself is very expensive and it is only...
