AI Thread Summary
The discussion centers on the challenges faced by a PhD student preparing for their qualifying exam, particularly the difficulty in solving practice problems due to a lack of foundational knowledge in classical mechanics, electromagnetism (E+M), and statistical mechanics/thermal physics. Recommendations emphasize the importance of revisiting undergraduate textbooks that the student previously sold, as familiarity with these texts can significantly aid in preparation. Suggestions for specific textbooks include Marion and Thornton for mechanics, Reif or Kittel for statistical mechanics, and Marion and Heald for electromagnetism. Additionally, it is highlighted that solving problems is crucial for preparation, and utilizing university library resources can be beneficial to avoid repurchasing all textbooks. Understanding the expectations of the specific graduate program is also advised for tailored preparation.

So I am studying for my phd program's qualifying exam and I find that I can solve hardly any of the practice exams from the last 10 years (not able to do any of the problems). I clearly am lacking the basics. Can someone recommend some books to study to get an undergraduate physics level understanding of upper level classical mechanics, E+M, and stat mech/thermal physics? I already own Griffith's quantum mechanics book. All my other textbooks I sold back to the bookstore.

Thanks!

As you have discovered, that was a mistake. I would buy another copy of those texts and start from there.

Some of them I kept but we moved to a new house and I don't know what happened to the other ones. :(

I am not sure the texts I used in undergrad are good ones.
 
It doesn't matter if the mistake was that you sold them to the bookstore, or that you otherwise lost them. What matters is that you no longer have them. You spent months of your life working through each book, so you should get another copy. You might also want to get some other book, but the ones you need most are the ones you are most familiar with.

I see. Thanks Vanadium.
 
If you have some idea of the graduate school, you can see what preparation they expect for the qualifier. Graduateschoolshopper has files for graduate schools and the academic preparation they expect. Most importantly, I learned to do problem after problem. Reading background is sometimes necessary, but it is solving the problems that is the best preparation. If you have a university library nearby, it may not be necessary to buy back all your recommended books.

possibilities:
Upper level Mechanics: Marion and Thornton Mech of particles and systems?, or Symon Mechanics,
Upper level Stat Mech: Reif, perhaps Kittel Thermal physic, Sears and Salinger, or Zemansky
Upper level EM: Marion and Heald, Corson and Lorraine, Griffith,
Upper level QM: Griffith, Gasiorowicz, Eisberg and Resnick maybe, Liboff, Saxon?

but is best to consider the graduate school you expect to attend to be more specific.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
