Comments for physicspages.com

This blog is for comments and reports of errors on my physicspages.com 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.

Quantum Field Theory

Due to popular demand, I’ll try to restore some of the posts I had on quantum field theory. As I mentioned before, I don’t feel that my understanding of this topic is good enough for the posts to be all that useful, so please interpret them with caution.

I’m trying to get my knowledge of quantum mechanics up to a level where I can tackle QFT properly, but this will take some time.
