Math person wants to go into Mathematical Physics

[Unknot]

Hi.

I don't know much about physics, and I wanted to get into some mathematical physics. I want to learn, from a mathematician's perspective, quantum mechanics and general relativity (and if I am right these are two most popular "flavours" of mathematical physics?).

Someone (not a physicist) recommended Gustafson/Sigal "Mathematical Methods in Quantum Mechanics" and Wald's "General Relativity." Now I do know that there are books that grad students in physics usually look at. Goldstein, Jackson, Sakurai, etc. Do I need to look at those first? Or can I just jump into those two books? Also if you have some other suggestions that would be great.

Oops I think I posted in the wrong section. I suppose it should really be in "science book discussion"

how much differential geometry do you know? i would start with a classical mechanics book like arnold v.i's if you're not that good at differential geometry or walter thirring's book if you are that good.

I would say I know enough to pass a qual in differential geometry.

I'm pretty much like you: I learned quantum mechanics and relativity from a mathematician's perspective (mainly because the courses were taught by the maths department!) How much classical mechanics have you studied? If you haven't studied any, then it will be best to start off there, but I imagine you've got at least a little under your belt. For quantum mechanics, the set text for my course was Gasiorowicz: quantum physics, which isn't a bad book, from what I remember, and was chosen by the lecturer as being a good book for mathematicians. As for relativity, you should probably learn special relativity first. I can't remember what I used, but see here (http://math.ucr.edu/home/baez/physics/Administrivia/rel_booklist.html) for a good review of textbooks. For GR I would recommend d'Inverno or Schutz as both being good books, but again, see the list for more info.

Finally, I've moved your thread to the science book discussion forum.

I hope to comment more in this thread, but, right now, exhaustion limits me to Quantum Field Theory: A Tourist Guide for Mathematicians by Gerald Folland,

https://www.amazon.com/dp/0821847058/?tag=pfamazon01-20.

I've only had this book for about ten days, but I think it's a real gem and the book that I've been waiting for fifteen years for someone to write.

A recent book that I found is https://www.amazon.com/dp/9810220340/?tag=pfamazon01-20 by John Baez and Javier Muniain. John Baez is a mathematical physicist and writes a ton of stuff on his website. This is a book I really look forward to going through soon.

Thanks for the suggestions on books, they all look good.

I also found this book and agree with George's assessment.
