Free ebooks from Springer

If you need something to cheer you up during this coronavirus pandemic, the publisher Springer is offering a number of scientific books for free (in electronic form), presumably as an aid to anyone wishing to study at home. The list doesn’t include any of the books that I’m doing posts on, but it looks like there is a good selection of physics and mathematics books from a variety of fields, many of them aimed at the undergraduate level, so it’s worth checking out. The books are available as PDFs, with some of them also in epub format. You can find the list here.

I imagine this offer will last only as long as the pandemic lasts, so it’s worth checking it out sooner rather than later.

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.

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.
