What follows is a list of topical pointers into the lecture notes for my Intro course on MATHEMATICA. Pick one, and take a look. The notes were created by writing out a plain-text version of the MATHEMATICA Notebook that I teach the class with. You can grab the actual notebook itself from right here. If you save it to a file, you can load it into a MATHEMATICA session. This is probably much more effective than trying to wade through the plain text that follows.
