Much of the course material will be available via the World-Wide-Web (WWW) on the class site http://online.physics.uiuc.edu/courses/phys150/fall03/
The Home Page contains current information on the class, and links to other pages that contain the basic information for the course, the homework, gradebook, and the syllabus that will be updated during of the course. The syllabus will also have links to the lecture slides, notes, and homework. A separate page of Links to Web resources is linked to the main page. Many of these are excellent resources for history, beautiful and instructive images of natural phenomena, working Java demonstration programs, etc.
