Commenting on or reporting errors in posts

This blog is used by me mainly to report new posts on physicspages.com, (you can sign up to new posts by entering your email in the box on the right) but you can also submit comments and error reports here. To make a comment or error report:

  1. Copy the title and/or the URL of the post you wish to comment on.
  2. Click on the <number> comments link at the end of this post (<number> is the current number of comments and will vary).
  3. If the <number> comments link isn’t visible, scroll to the bottom of the page until you find a ‘Leave a reply’ box.
  4. Scroll to the end of the comments and add your comment there.
  5. If you’re commenting on a particular equation in a post, please make sure you include the equation number in your comment.
