The class consists of four units covering the topics listed below,
one per week. The units are downloadable as either Adobe Acrobat files
or Microsoft Word documents. Download the Acrobat
Reader for almost any platform for free.

There are assignments included with each unit, due at midnight Eastern Time on the following Sunday. Send them by e-mail to the address given in the registration letter. Please use plain text representations of math as described on the Math page.

I also urge you to visit the Relativity Discussion Board. Think of this as a kind of student lounge for discussions about the class. I will also occasionally post reading suggestions and other class material.
