The newest version of iTunes has added support for so-called podcasts. For those that don't know, a podcast is an audio file that can be downloaded and played back on a computer or an iPod. This audio format has been available for a while, but has required a fair amount of work on the part of the recipient. Apple has now built that all into iTunes so it's a lot easier to do. The iTunes programs runs on either PCs or Macs, so we can avoid computo-religious wars. In almost all cases, the podcasts are free. You "subscribe" to the podcast and your computer automatically receives new programs as they become available. The audio format is compressed, so those folks with modems might be able to receive them without too much bother. Anyway, I installed the new version last night and went looking around to see what I could find. It turns out there are quite a few astronomy shows and even more on general science topics. For example, the NPR show "Science Friday" is there. The audio quality is quite good. Sure beats talk radio--although you can get that too, if you need a certain daily dose of invective. So there it is. Pretty cool.
