“Them” means those problems that I have stated here. “I’m not struggling with basics, it’s just that I don’t understand them “marcusl said:Not understanding is even worse than struggling.
We have talked to each other and I respect you. The problem is that “those” proofs are not at all “obvious” to me although I don’t struggle with basics.hutchphd said:To misuse Pauli's famous quip: I fear that you are "not even" struggling.
You should be building a tabernacle of ideas. When presented with a new idea one needs to treat it like an enemy: shine a light on it and prod it with a stick. See if it makes sense in your present knowledge framework and ascertain where it fits. You may need to adjust parts of the scaffolding for your present construction to make room. If this is not a struggle your method is suspect. I feel you need a teacher and recommend that you seek one (or several) for this.
I don’t think you really want me to have a good luck.Vanadium 50 said:Best of luck.
I have given you my advice.Adesh said:“Them” means those problems that I have stated here. “I’m not struggling with basics, it’s just that I don’t understand them “
Yes and I shall follow it.marcusl said:I have given you my advice.
I will save this post of yours forever.hutchphd said:@Adesh Thank you for the kind words. I do think you may have great potential.
I hope your confusion is just a matter of perspective for you. This perspective is perhaps the most important part of learning and unfortunately difficult to provide from a distance. I do hope there is somewhere you find more personal teaching because it too is important. And sometimes it is better to have unanswered questions and just let them age a little. You may find the answer from an unexpected source in time and you need some confidence in that process. Great good luck.
Mondayman said:I like the look of the Alonso and Finn series, but it is hard to get for a reasonable price.
Would you say Alonso and Finn is closer to Purcell than it is to an introductory text like HRW or Serway? I find Serway to be a little easy on the math.MidgetDwarf said:True. But sometimes, it can be had for under $100. This is one instance, where the information and presentation, outweigh the cost. I would gladly pay $400 for this series, and not regret it.Not sure if the 1st edition is out of copyright. I have seen pdfs of the book floating around. But I'm not sure of the legality of said copies.
Yes. Alonso does not skimp on mathematics. neat derivations, which allows readers to think how the theory is connected. Beautiful explanation of the Lorentz transformation, momentum. etc. Problems are way easier than Purcell, but they compliment each other so well. The beauty of Alonso comes in volume 2 and 3.Mondayman said:Would you say Alonso and Finn is closer to Purcell than it is to an introductory text like HRW or Serway?

This is a problem of overreaching. The study of physics is a progression where each subject builds upon everything that came before. One won’t move forward (to quantum theory, for example) if there are holes in one’s preparation and mastery of basics, up to and including E&M.Ishika_96_sparkles said:and @marcusl @PeroK

Yes your words are true our case here in this thread is different. My situation is such that I'm an autodidact from 3 years, so when I get some doubt no matter how basic I ponder over it and if I myself don't get a way out of it I just ask it over here. When an autodidact ask some basic doubts, people tend to think "Why is he asking such an obvious thing?" because when teachers teach those topics they cover some of the usual doubts (due to experience they know it) or it can happen that someone else in the class ask a doubt and things will get clear up.marcusl said:This is a problem of overreaching.

Consider this example: In Griffiths, when he takes the curl of magnetic field, he just writes
$$ \left( \mathbf J \nabla\right) \hat{ r} = - \left (\mathbf J \nabla '\right) \hat{ r}$$
Without much clarification, but in the book suggested by @vanhees71 sir (Greiner's EM) this point is explained properly, that is how we moved from unprimed gradient to primed gradient. Just imagine if this thing were to be taught in a class room, this point would have been a obvious one because the instructor must have known it to be a common doubt.
So, this is the case here. I thought things would going to fine after a great reply of @hutchphd sir, but I don't know why a new user did something like that to me. But I have no hard feelings for anyone, everybody cheers.

No, what you told us in the first quote above is that you don't understand basic concepts. I recognize that English is not your first language, but the way pronouns work in English is as placeholders for the nearest preceding noun. What you wrote in the first quote above is equivalent to "I’m not struggling with basic concepts, it’s just that I don’t understand basic concepts."Adesh said:I told you I’m having no problem in basics.
Yes, that may be the case. @Vanadium50 asked me and suggested me his advice in a good faith and I'm thankful to him, I was rude to @Vanadium 50, I accept that. I communicated badly, I accept that. Everyone gave their precious time and effort, I appreciate that and will be grateful to them always.Mark44 said:No, what you told us in the first quote above is that you don't understand basic concepts.

If that was not what you meant, then you weren't communicating clearly. Everyone who saw what you wrote interpreted it exactly as I have explained here, and this is why there were so many replies saying that you should go back to basics if you were having trouble understanding them.
Is first edition substantially different from fourth edition?Meir Achuz said:You might try Griffith's 1st edition which was nuts and bolts and less personally anecdotal.
