Discussion Overview

The discussion revolves around recommendations for advanced mechanics and electrodynamics textbooks following Kleppner and Kolenkow (K&K) and Purcell. Participants explore various options for Lagrangian and Hamiltonian mechanics, as well as the suitability of Griffiths' Electrodynamics and Quantum Mechanics for further study.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest Taylor as a good mechanics book after K&K, although it is noted to have limited coverage of Hamiltonian mechanics.
  • Gregory and Greiner are also mentioned as alternative mechanics texts, with links provided for reference.
  • Griffiths' Electrodynamics is generally regarded as a strong follow-up to Purcell, with some participants considering it one of the best physics textbooks.
  • There is mixed feedback on Griffiths' Quantum Mechanics, with some participants expressing a preference for other texts.
  • One participant recommends studying Griffiths' Electrodynamics concurrently with Purcell for a more efficient learning experience.
  • Concerns are raised about the difficulty of problems in Griffiths compared to those in Purcell, with varying personal experiences shared regarding problem difficulty.
  • Melvin Schwarz's "Principles of Electrodynamics" is suggested as a mathematically sophisticated alternative to Griffiths and Purcell, while Jackson is critiqued for its focus on mathematical rigor over pedagogical clarity.
  • Zangwill is recommended as a better graduate-level E&M book than Jackson, emphasizing insight and intuition in Electrodynamics.

Areas of Agreement / Disagreement

Participants express a range of opinions on the recommended textbooks, with no clear consensus on the best choices. There are differing views on the difficulty of Griffiths' problems compared to Purcell, and mixed feelings about Griffiths' Quantum Mechanics.

Contextual Notes

Some recommendations depend on personal preferences and experiences, and there is uncertainty regarding the comparative difficulty of problems across different textbooks.

What would be a good mechanics book after K&K that includes Lagrangian and Hamiltonian mechanics? Also, would Griffiths' Electrodynamics be suitable after Purcell? What about Griffiths' Quantum Mechanics (ignoring the math pre-reqs)?

For mechanics, I think Taylor is pretty nice: https://www.amazon.com/dp/189138922X/?tag=pfamazon01-20

Griffith's Electrodynamics is a very good book. Some call it one of the best physics textbooks ever written, so yes: do that after Purcell.

I'm not really a fan of Griffith's QM, but others seem to like it a lot.

Calkin, Taylor, Greiner, Thornton and Marion are but a few (although I hate Thornton and Marion with a passion).

If you can, try your best to do them concurrently. This is the most efficient way to use Griffiths if you have Purcell. That way you can move on to more advanced EM texts (e.g. Jackson) without wasting extra time because Griffiths is only a hair's width more advanced than Purcell in terms of material covered.

What about it? It's a brilliant QM book but you should focus on mastering analytical mechanics and EM first.

Based on what I've read, I'm going to get Taylor, Gregory, and Griffiths E&M, QM can wait. Thanks for the help!
 
By the way, how do the problems in Griffiths compare (in difficulty) with those in Purcell? I'd be lucky to solve 3 2 star problems in Purcell (2nd Ed. When Morin added more problems). It reminds me of his intro to CM book, which really drove me crazy. In a good way.

Edit: I asked this because WannabeNewton said its a tad harder when it comes to material (which I'm fine with) but that doesn't necessarily mean harder questions (or does it?).

Griffiths problems are on the whole easier but not by much, at least for me personally.
 
Principles of Electrodynamics by Melvin Schwarz is a good book that is not nearly as difficult as Jackson but much more mathematically sophisticated than either Griffiths or Purcell. Personally, I think Jackson is only OK. Zangwill is a much better graduate level E&M book than anything (including Jackson) on the market. Jackson is mainly concerned with showing you that he knows a lot of math. Zangwill is concerned with giving you insight into Electrodynamics and developing your intuition through examples, applications, and excellent pedagogy.
