What chapters can I skip when self-studying Griffiths electrodynamics?

Click For Summary

Discussion Overview

The discussion revolves around which chapters of Griffiths' electrodynamics textbook can be skipped during self-study without losing continuity in understanding physics. Participants explore the importance of various chapters in relation to broader physics education and personal study goals.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants suggest that the importance of chapters depends on individual goals and the specific areas of physics one intends to pursue.
  • Others argue that there is no universally agreed-upon framework for what constitutes essential content in physics textbooks, leading to variability in study approaches.
  • Several participants express skepticism about the idea of being "done" with a physics book, emphasizing the continuous learning aspect of the subject.
  • One participant mentions the potential need to revisit skipped topics if encountered in more advanced texts, such as Jackson.
  • There are differing opinions on the quality of Griffiths' textbook, with some participants recommending alternative texts like Wangsness, Sommerfeld, or Zangwill, while others defend Griffiths as a solid introductory resource.
  • Concerns are raised about the implications of skipping chapters, particularly regarding foundational concepts like radiation and its relevance to technology.
  • One participant shares their background as a medical student studying physics out of passion and preparing for a biophysics PhD, highlighting the need for efficient study strategies.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which chapters can be skipped, with multiple competing views on the necessity of various topics and the overall value of Griffiths' textbook compared to others.

Contextual Notes

Participants express a range of opinions on the relevance of specific chapters, indicating that the discussion is influenced by personal experiences and educational backgrounds. There are references to different educational systems, particularly regarding the classification of medical degrees.

Have you tried leonard susskinds Quantum mechanics - the theoretical minimum?
For studying classical electrodynamics? 🤔

I thought he was also using Griffiths for QM and wanted an alternative to the QM book?

His QM book is on the other hand REALLY BAD, but I find no alternative at my level so I'm kinda stuck with it🥲.

I guess the title confused me …

It is often said that Griffiths QM book confuses students, perhaps it is related to that?

Junior level classical mechanics, quantum mechanics and e&m are the foundations of the physics degrees. Skipping things here is risky.

That being said, if you are getting relativity someone else …

You might try Zwiebach for quantum. It has the advantage of the MIT opencourseware lectures.

If you already covered all of the chapters in Purcell, then you will find a fair amount of overlap with Griffiths. If it were me and I wanted to skip a couple of chapters, I would skip the ones about fields in media since Purcell has reasonable coverage of those. On the other hand I would definitely not skip the chapters on waves, conservation theorems, radiation and special relativity. Purcell skips a lot of that material or treats it in a way I found more confusing.

And by “cover” i mean read the chapters and solved some number of problems in the book.

Concerning relativity Purcell confused me more than it helped. I think Griffiths is a much better book anyway.

The question was just me making sure to be economical and not be spending time on things generally skipped in college, because I only have 2 years left. So do I have to read an entire book for each remaining subject?
<<Emphasis added.>> This thread has forked into different paths. But I believe this is your underlying question.

It's been many moons since I was in school. But as far as I can remember, the professor typically did not go over the textbook from cover to cover. This even applied to several courses in which the professor wrote or co-wrote the textbook.

Often a textbook includes more material than can be covered in a one-semester course, or even a two-semester sequence. Often a textbook includes material that is not relevant to a department's particular curriculum (which may change over time), or contains material that is covered in a different course using a different textbook (which may change over time). On the flip side, often the professor supplements the primary textbook with portions from other textbooks, or from his own notes.

So my advice to you is what I wrote previously: There are many university websites describing details of their courses. Check those out as guides for your self-study. They likely won't all agree in their entirety. But there will be topics with high overlap.

I already referenced that above in my Reply #10. But I would encourage the OP to take a sampling of other universities. In the context of online resources, there are frequent references to MIT because of their extensive OpenCourseWare and because, well, it's MIT. But important caveat: Their course presentation in many instances is atypical, which isn't surprising since it's not a typical university.

Example: I use different parts of my book as the main reference in three different courses.

I think Griffiths electrodynamics is fantastic and not all that sloppy. His QM book is on the other hand REALLY BAD, but I find no alternative at my level so I'm kinda stuck with it🥲.
You can try Quantum Theory by David Bohm
