Physics Pages

This site contains my notes and solutions to various problems in some textbooks in physics and related fields. The site is fairly technical, in that I use whatever mathematics is required to explain the various topics. It is most useful to those who are either taking a structured course at a university or online, or to those who are working through a topic on their own. Although I've tried to make most articles self-contained, there is no substitute for a good textbook and/or an organized course. As such, I'd strongly recommend you buy a textbook (it doesn't have to be one of the ones I've used; there are many to choose from) and use that as your primary source. There are also many good courses available online for free at such sites as edX and coursera.

Comments pointing out errors in an article or requesting clarification of some point in an article are welcome. As this site is not technically a blog, you will need to use the auxiliary blog to post comments.

If you want to comment on a particular article, PLEASE make sure you include the URL of the article (just copy and paste it from your browser's address bar). Please also note that due to time (and knowledge) limitations, I am not able to work through calculations or explain topics not covered in one of my articles. You are welcome to submit comments of that sort, but I will simply post them in the hope that some other reader will respond.

I will use the auxiliary blog to announce new articles added to the main site, so if you want to be kept up to date, check that blog 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 seeking help on some topic in physics that isn't covered here, you may find Physics Forums helpful.

A historical note for those who followed my old site. The original site was run using WordPress, but the underlying database got corrupted and was not possible to repair, even from the backup. As a result, I've rebuilt the site without using WordPress, so all the posts are now PDF files. Although PDFs have their problems, in that some browsers don't display them fully without a plugin, they have the advantage that the Latex mathematics displays more neatly, and some symbols not available in WordPress's implementation of Latex are now available.

The following is a test usage of Google's Custom Search feature. I haven't tested it extensively, but it does seem able to search through PDFs, so hopefully it will be useful.
