Alternative to 'Introduction to Quantum Mechanics' by Griffiths

Click For Summary

Discussion Overview

The discussion revolves around the challenges faced by students using the textbook 'Introduction to Quantum Mechanics' by Griffiths. Participants express their difficulties with the material, particularly with the presentation of Schrödinger's equation and the problem sets. They seek alternative resources that may provide clearer explanations and more worked examples.

Discussion Character

  • Exploratory
  • Debate/contested
  • Homework-related

Main Points Raised

  • Some participants express frustration with Griffiths' approach, noting that Schrödinger's equation is introduced without sufficient explanation, making self-learning challenging.
  • One participant suggests that Dicke and Wittke's book contains many manageable problems that could serve as a confidence builder.
  • Another participant mentions that, despite initial difficulties, they have developed a strong grasp of the concepts through perseverance and recommend keeping Griffiths as a supplementary resource.
  • A participant recommends Nouredine Zettili's "Quantum Mechanics: Concepts and Applications" as a preferred introduction to quantum mechanics.
  • Another suggestion is Gary Bowman's book, which is noted for its similar notation to Griffiths and is intended to supplement other textbooks.
  • One participant advises reviewing linear algebra, calculus, and differential equations to better understand the physics concepts presented in Griffiths' text.
  • Some participants reassure others that it is normal not to understand Schrödinger's equation immediately, emphasizing that Griffiths' text is designed to help students engage with calculations and problem-solving first.

Areas of Agreement / Disagreement

Participants generally agree on the challenges presented by Griffiths' textbook, but there are multiple competing views regarding the effectiveness of different supplementary resources. The discussion remains unresolved regarding the best alternative to Griffiths.

Contextual Notes

Some participants mention the need for a solid understanding of prerequisite subjects like linear algebra and calculus, indicating that the difficulties with Griffiths may be compounded by gaps in foundational knowledge.

We just started the course on Quantum Mechanics and this is the 'official' textbook we're using. I have heard many people speak fondly of this book and so far I do like that the author writes in a colloquial style. However, reading it, I feel dumb. Schrodingers equation is just thrown out there right at the start without any explanation or introduction and it seems like I'm just expected to understand it. Problems are also difficult and I can't really solve most of them. Example problems are far and few in between. I like to self-learn and I'm having a hard time doing that with this book. Anyone know of an alternative? Preferably one with lots of worked out problems.

I remember that Dicke and Wittke had many problems that are doable. I used it as a confidence builder when learning quantum mechanics.
 
I understand your difficulties, as that is what I'm suing right now, as well. At first problems were quite difficult, but I feel that I have developed a very strong grasp of the concepts, after struggling to figure out problems on my own. Now I feel fluent in the language Griffiths uses, and the arguments flow smoothly in my mind. If you do find an alternative, I would recommend at least keeping Griffiths as a supplement, as he is pretty thourough.

Geez, people will sue over anything!
 
https://www.amazon.com/dp/0199228930/?tag=pfamazon01-20 by gary bowman would be a great supplement to griffiths, especially since the notation is very similar between the two books. bowman's book isn't really a textbook and is written almost specifically to help supplement other textbooks and courses. there is also a solutions manual for griffiths' book, but use caution as you don't want to rely on constantly looking up the solution.

another thing that i think would help with this text would be to review your linear algebra, calculus, and differential equations notes and textbooks. having a solid recollection and understanding of these subjects helps you concentrate on the physics principles without getting lost in the calculations.

also, don't worry about not understanding Schrödinger's equation from the get go. this text is more getting you used to being able to work with it and use it to solve problems, and not to be able to derive it. griffiths' book is really great in that it helps you get dirty with working through a bunch of calculations and problems, letting you learn the more abstract theory later.
