Lectures and Notes – 2011a

Note: None of this will make sense without a text. Click here to see the text you will require to make any sense out of these lectures.

PLEASE NOTE: If you are having problems viewing the files, click here.

The MP4 lecture files are for web enabled phones or IPod/IPad stuff.  The Real Video files (.rm) are for use on your computer using Real Player. You will need Real Player to view the Real files. You can either left-click on the Lecture files and stream them over the web, or you can download them to your computer and play them from there by right-clicking “Download Real Video” then “Save Target As.” You cannot download the .rm files by merely right-clicking on them. That will only give you a short one-line rtsp file. Clicking on that will again stream the file over the web.

You will need Adobe Reader to view the Notes files. The Notes files can be viewed by left-clicking on them or you can download them to your computer by right-clicking and then “Save Target As”.
