This blog is for comments and reports of errors on my site. I will also post notifications of new articles published on the main site using this blog, so if you want  to be kept up to date, check here regularly, or else  subscribe to it for email notifications. I realize this may look like a roundabout way of organizing things, but I don’t trust WordPress with anything substantial any more.

If you’re reporting an error or want clarification of an equation in an article, PLEASE include:

  • The URL of the page – just copy this from the browser’s address bar at the top.
  • The equation number containing the error.
  • And of course, what you think is wrong with it.

Thanks, and I hope you find the new site as useful as the old one.

The original post date of each article on the physicspages blog is given at the top of that article.

For articles posted after September 2017, there will be a separate post on the comments blog (this blog), which you can locate in the ‘Archives’ list at the right. You can leave a comment on that particular article from its corresponding entry in the comments blog.

Articles earlier than September 2017 were part of the old site and don’t have
a separate post in the comments blog. If you want to comment on one of these older articles just leave a comment to this header post.

    In your solution to Shankar’s Quantum Mechanics, problem 12.03.01, equation 9 and the subsequent ones, you’re missing a factor of rho in the integrand. (The rho is also written in the question, I think it’s a typo)
    Also, I think the paragraph after equation 11 does not necessarily prove equation 12.
    Thanks for your detailed solutions!

      Fixed now. Thanks.
      As for equation 12, in the textbook it says to show that “it is enough if \psi obeys” Shankar’s equation 12.3.6 (my equation 12), which is certainly true, since then the value of \left.\psi_{1}^{*}\psi_{2}\right|_{0}^{2\pi} in equation 11 is zero.
