Astronomy 2, Special Relativity, podcast lectures

large feed iconI'm making available recordings of my A2 Special Relativity lectures via a podcast (see the course home page for other downloads).

Added 2018: The notes below were last updated in 2013, and so may now be slightly out of date.

You can use podcasts using a variety of tools, of which the best known is Apple’s iTunes. Instructions for iTunes and others are below.

The crucial bit of information is the URL of the podcast feed, which is;rss

If you have any problems with the feed, or with the enclosed MP3 files, do let me know fairly urgently.

Please do let me know how you get on. I’m interested in whether you use these recordings, how, when, why, where, plus any other feedback that occurs to you.

Subscribe to the podcast: you can download the podcast to a portable device, and re-listen to the lectures there. Your podcast reader will automatically download updates to the podcast.

How do I use this?

Podcasting is most immediately associated with Apple’s iTunes, so the instructions for that come first. It is not specific to iTunes, however, and there are multiple other ways you can use the podcast feed.

Selecting the subscription menu item in iTunes Within iTunes, select the ‘Subscribe to Podcast...’ menu item, under the `Advanced' menu, and copy the above URL into the box that appears. That’s it! You should now see the lecture notes podcast as one of the podcasts (perhaps the only podcast) you’ve subscribed to.

ITunes is available for OS X and Windows (though it’s reportedly a bit of a pig on Windows).

Other tools

There’s a whole clatter of aggregators at podcastingnews. I’ve used very few of these: if you have any recommendations or experience, please pass them on.

If you click on the feed URL link above, Safari will handle the page appropriately, and you can simply bookmark that page. It also has a little ‘RSS’ icon in the address bar.
If you’re using a reasonably recent version of Firefox, you should see the RSS feed icon RSS feed icon in the address bar: simply click on that, and you should be prompted to save a ‘live bookmark’.
Juice (aka, iPodder or Lemon)
I’ve heard good things of Juice (OS X, Windows, and Linux; this seems to have been until recently called iPodder, or possibly Lemon). A quick play around suggests that it seems to work OK.
Any others?
If you’ve instructions for any other tools or browsers, please let me know.

Doing it by hand...

If you don’t want to bother with the RSS feed (which is really what makes it a podcast rather than just a bunch of MP3s on the web), then you might just want to pick up the MP3s directly: For that, see the podcast’s tagging interface

(the point of the podcast is that you don’t have to bother checking back to this page to see if there have been any updates, but if this is the only podcast you listen to, then there’s not much gain in that).
