I took the time to find, zip, and post these lectures. If you can't view the format, too bad. Don't read them. Alot of people can view the PS format, especially because of its prominence in science. The PDF conversion makes the quality take a huge hit and there's nothing I can do about that.
What about people who are too lazy to DL Acrobat and view PDFs? Should I convert it to DOC format? Those are both Windows formats, than I have to convert it to Linux. Then the people on BeOS will start complaining.
If you want to read the lectures, download the program. Otherwise, f' off.
