The discussion revolves around the approach to studying quantum mechanics (QM) using Griffiths' textbook, specifically whether to memorize derivations and proofs or focus on understanding and applying the final results. Participants also address the challenges of solving problems without external help.
Participants generally agree that understanding and applying concepts is more important than memorizing derivations. However, there is no consensus on the best approach to problem-solving, with differing opinions on whether to skip difficult problems or attempt them regardless of difficulty.
Some participants note that Griffiths' textbook includes a limited number of problems, which may vary in difficulty, and that the original poster's ability to solve problems may depend on their level of understanding.
Zerkor said:so, is it okay to skip the problems or should I solve them all?
NathanaelNolk said:I guess, you should try your best, and see which problems you're able to solve. If you see you can't solve any of them, I suggest re-reading the chapter. If you can do I'd say 60-70% of the exercices, you can move on to the next chapter. But I don't know much about Griffiths Introductory, so if it really is hard, then you should just skip the problems that are way to hard, at your level of understanding.
Isn't there anyone (a teacher, a physics student or such) who could help you out with this book ?
F=qE said:As an undergrad QM student 2 years ago, I did QM with the Griffiths book. I argue it is far more important to be able to do the problems than memorize the derivations. My exams were never straight derivations. The problems really aren't too hard from Griffiths - some were tedious algebra, but never crazy impossibly hard. It's designed for a 3rd year undergrad.
My point exactly. If you (OP) wanted to see if you were doing the problems right - all you needed was a simple google search.NathanaelNolk said:Is that what you're looking for ? <<link deleted>>
My you in the above was directed at the op, sorry ill edit that.NathanaelNolk said:By now, you can even legally find entire textbooks, so I guess you shouldn't have too much trouble finding the solutions of such a book.
