Discussion Overview

The discussion revolves around a free book titled "Quantum Mechanics for Engineers" by Dommelen, with participants sharing their thoughts on its content, structure, and relevance to their understanding of quantum mechanics. The conversation touches on the prerequisites for studying quantum mechanics and the author's humorous writing style.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants express appreciation for the book's title and content, noting its alignment with their prior learning experiences.
  • One participant mentions downloading the PDF version but prefers the HTML version for its ease of navigation and linked solutions.
  • A participant shares their experience of watching a lecture by Professor Balakrishnan and reading the corresponding section in the book, finding it beneficial.
  • Another participant questions whether a complete understanding of classical mechanics is necessary before starting quantum mechanics, stating their familiarity with Hamiltonian and Lagrangian mechanics.
  • Some participants suggest that while a basic understanding of Lagrangian and Hamiltonian mechanics may suffice, a deeper comprehension of classical mechanics and relevant mathematical concepts is essential for fully grasping quantum mechanics.
  • One participant highlights the author's humorous approach in the book, citing specific examples of light-hearted commentary on physics conventions.

Areas of Agreement / Disagreement

Participants generally agree on the value of the book and its content, but there is no consensus on the necessity of mastering classical mechanics and mathematics before studying quantum mechanics, with differing opinions on the prerequisites required.

Contextual Notes

Some participants express uncertainty about the extent of classical mechanics knowledge required, indicating a reliance on personal experience and varying interpretations of the material.

Very nice, thanks! I like the title :smile:

I've bookmarked it and will go through it more soon. I like how it starts with a review of what I learned in undergrad and moves on to subjects I've read about on the PF and beyond. Thanks @smodak :smile:

Thank you. I downloaded the pdf to read, however, i actually find the HTML version easier to follow (the HTML version is also hot linked to solutions etc.). I was just watching this lecture by prof. Balakrishnan and then I read the corresponding section on the book, and I must say it was a pretty good experience. Now I know this material a bit, so, it will be great if someone who does not can comment on the quality. So far, in my experience, I think the book is very well written.

I am very interested to follow Balakrishnan's lectures. Just tell one thing: for starting quantum, do you need to go through the whole classical course? I have an idea of Hamiltonian and Lagrangian and also how to draw phase trajectories and understand autonomous systems. Is that enough?

By the way, thanks for the book :smile:

In my opinion, you should be able to follow to some extent if you know the idea of Lagrangian and Hamiltonian. However, he uses classical mechanics (and electromagnetism) a lot (for analogies etc.), so to really understand and appreciate, you will need to really understand classical mechanics well. He also goes on some tangents about l2 spaces and complex analysis so your math (complex analysis, linear algebra, differential equations) should be strong. My recommendation will be not to skip classical mechanics or any math prerequisites. It is a slower process but a more rewarding one. Unfortunately there is no shortcut to learning physics. Great lectures by the way.

von Dommelen, the author of the book, also has a good sense of humor. For instance, in Copyright and Disclaimer he says:
"However, in this web book, I do try to correct “inaccuracies,” OK, blunders, pretty quickly if pointed out to me by helpful readers, or if I happen to think twice."
Or at page 280:
"Normal people would therefore indicate it as O or 0. However, physicists are not normal people. They indicate the origin by Γ because the shape of this Greek letter reminds them of a gallows. Physicists just love gallows humor."
