Lectures

The PowerPoint Show (.pps file) is embedded with an audio narration which starts automatically and runs concurrently with the slide show. To listen to the lectures with powerpoint slide show running automatically, just click on the link on the pps file, and choose "Open with Microsoft Office PowerPoint (default)"; to manipulate the slide show and the audio file manually, click on the link to the wav file also to download it to your desktop. To save the PowerPoint Show to your computer and listen to it later, right click on the link and choose "Save Link As".
