Is dirac's "The principles of Quantum mech." a good book?

Click For Summary

Discussion Overview

The discussion centers on the suitability of Dirac's "The Principles of Quantum Mechanics" as a textbook for learning quantum mechanics (QM). Participants express their preferences for books that balance mathematical rigor with intuitive understanding and seek recommendations for suitable alternatives.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant expresses a desire for a QM book that balances mathematics and intuition, mentioning Dirac's book as a potential option.
  • Another participant suggests "QM: The Theoretical Minimum" by Prof Susskind, questioning its suitability for beginners.
  • A participant who owns Susskind's book notes that it is not a standard textbook and has more descriptive content than mathematical rigor, but still contains real mathematical concepts.
  • There is a suggestion that reading Susskind's book first could help build intuition before tackling more complex textbooks.
  • One participant advises that Susskind's book assumes some knowledge of calculus and differential equations, targeting readers who wish to deepen their understanding of science.
  • A participant who has read both Dirac and Susskind expresses a preference for Susskind, stating that it is more accessible for beginners and covers essential topics in QM.
  • Another participant mentions that Susskind offers online lectures that complement the topics in his books, although they have not personally evaluated the lectures.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the suitability of Dirac's book for beginners, with some expressing reservations about its accessibility compared to Susskind's work. Multiple competing views on the best approach to learning QM remain evident.

Contextual Notes

Some participants highlight the need for a foundational understanding of calculus and differential equations to engage with the recommended texts effectively. The discussion reflects varying levels of familiarity with QM and differing preferences for pedagogical approaches.

I have not read any other QM books,i have little knowledge on that subject and want a books that uses mathematics in academic levels but is easy to get the grips on and also builds intuition and explains the phenomenons in a good manner.I do not want a book that emphasizes on mathematics or intuition alone but something that has it all.I have heard that Dirac's book is a great book but i wanted to know your opinions.Feel free to suggest other books(bear in mind that i have got Griffiths book on QM from the university library).

I have a copy and from the reviews many people like the treatment. It's not a standard textbook and has more wordy description than math. However. The math is real not watered down to something trivial like popular science might be.

so,it might be better if i read this first so as to build up intuition and then going for the harder textbooks which have more complex math,right?
 
Yes, it assumes you can do calculus and differential equations to some extent. The focus of the book was for people long out of school who wish to understand science in a deeper and truer sense.

Susskind has a similar book on classical mechanics that is quite good too and you may want to check it out too.

I advise to first study the Schrödinger equation.
 
I read Dirac and Susskind . Susskind is good for beginners ( I am am still a amatuer) he does everything you should know to get started with QM, that is harmonic oscilators, quantum logic, SE and so on that are all derived so that anyone with a bit of knowledge of calculus can derive. It mostly doesn't get harder than the easyest of differential equations. I didnt much like Dirac and I don't think he is recommendable for beginers of QM.
But Susskind is a good idea.
 
Plus he also has online lectures parrallel to the topics in his books ( I can't say if they are good, because I couldn't be botherd to watch them), the link is in his book but they can also be found at stanford university website.
