Discussion Overview

The discussion revolves around the best introductory textbooks for quantum mechanics (QM), comparing various options including Griffiths and Dirac, as well as other texts like Sakurai, Ballentine, and Zettili. Participants share their experiences and preferences, considering factors such as mathematical rigor, clarity, and suitability for self-study.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express strong opinions for and against Griffiths, citing its clarity and excitement versus its perceived sloppiness and inadequate preparation for advanced studies.
  • Dirac's book is acknowledged as a classic, but some participants caution against using it as a first text due to its age and complexity.
  • Several participants recommend alternative texts, including Sakurai and Ballentine, with varying opinions on their suitability for beginners.
  • Concerns are raised about the mathematical prerequisites for some texts, particularly Ballentine, which may require prior knowledge of functional analysis.
  • Zettili is mentioned as a good option for practical calculations but criticized for lacking depth in conceptual material.
  • Some participants suggest using multiple texts to cover different aspects of QM, including a mix of introductory and advanced materials.
  • There is a consensus that different books offer unique strengths, and sticking to one text may not be the best approach for comprehensive understanding.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best introductory text for quantum mechanics. There are multiple competing views on the strengths and weaknesses of various books, with no clear agreement on a single recommended text.

Contextual Notes

Participants express uncertainty about the adequacy of various texts for beginners and highlight the importance of mathematical background, suggesting that some texts may not be suitable without prior knowledge.

Who May Find This Useful

This discussion may be useful for students or self-learners seeking recommendations for introductory quantum mechanics textbooks, as well as those interested in understanding the diverse opinions on various texts within the physics community.

It's in the extended edition DVD; it doesn't show up in the regular version of the movie. Have fun with Shankar!

I intend to :cool:

I'm going to admit my age on this one, but here are some texts that I really like, but I'll warn you, they are all out of print:

McGervey, more modern physics that QM, but never the less a decent text.
Slater, Quantum Theory of Matter, every time I read that book I learn something else.
Schiff, another I one am not seeing mentioned.

Now, these texts are not filled with bra-ket notation, but I didn't learn that until late in my graduate career.

Well, I also like the older texts, e.g., Pauli's famous review on wave mechanics, Sommerfeld's "Atombau und Spektrallinien", Landau/Lifgarbagez Vol. 3 and so on. However, I'd not recommend to learn quantum mechanics from a text that overemphasizes wave mechanics and then within wave mechanics the time-independent Schrödinger equation. The abstract formalism is more appropriate to understand the structure of quantum theory and doesn't overemphasize the position representation and the wave aspects. In my experience, many students come to the wrong conclusion that only energy eigenstates have some physical meaning. Also scattering theory is often taught in the time-independent scheme from the very beginning, although it's much better to start from a time-dependent approach, using proper wave packets as incoming states rather than plane waves, which are not even states in the strict sense at all.

A lot of confusion can be avoided by starting with the Hilbert-space structure. However, of course, you must start with some intuitive picture, why one has to use this abstract formalism. I think, Sakurai does this in a very nice way.
