Mars (The MAthematics Research/education Server) is an experimental interactive MOO (Multi-user, Object-Oriented) server connected to the World-Wide Web. It is being set up and maintained by Mathematics graduate student Michael Brundage. Mars is accessible from the Math 126 web page, and will contain supplementary texts and interactive worksheets for Math 126, as well as an interactive ``bulletin board'' for students in the course to communicate with each other.
