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

Click For Summary
SUMMARY

This discussion centers on the self-study of Griffiths' Electrodynamics, specifically which chapters can be skipped without compromising foundational knowledge in physics. Participants emphasize the importance of context, suggesting that the decision to skip chapters should align with the learner's goals, such as preparing for a biophysics PhD program. Key chapters like Radiation, Conservation Laws, and Electromagnetic Waves are deemed essential, while others, such as Electrostatic Fields in Matter, may be less critical depending on prior knowledge from other texts like Purcell's Electromagnetism. Ultimately, a comprehensive approach to studying the material is recommended to avoid gaps in understanding.

PREREQUISITES
  • Understanding of classical mechanics concepts
  • Familiarity with calculus and linear algebra
  • Basic knowledge of electromagnetism from introductory texts like Purcell's Electromagnetism
  • Awareness of graduate-level physics program requirements
NEXT STEPS
  • Review the syllabus for intermediate Physics E&M courses at major universities, such as MIT's 8.07
  • Study the chapters on Radiation and Conservation Laws in Griffiths' Electrodynamics
  • Explore alternative textbooks like Zangwill's "Modern Electrodynamics" and Lechner's treatment of the subject
  • Investigate the admissions requirements for biophysics PhD programs to align study efforts with expectations
USEFUL FOR

Students pursuing self-study in physics, particularly those preparing for advanced studies in biophysics or related fields, as well as educators and curriculum developers looking to optimize physics education.

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.

You can try Quantum Theory by David Bohm
