These clips are to be shown, and discussed, in recitation the week of 7 April. The class will view these science-fiction situations that have to do with gravity, stellar collapse or black holes, and identify which features were incorrect, based upon what they have learned about black holes and relativity in the first parts of the class.
The clips appear in the form of MPEG files. If your computer has an MPEG viewer installed (almost all do, since all versions of Windows and Mac OS have built-in multimedia players), and if files of the type *.mpg are associated with it, the clips will open and run right away, when you click on their buttons below. This sometimes results in rather "choppy" audio and video performance if there's anything iffy about your network connection (e.g. if you're off campus and/or using a phone-line connection). To avoid this, RIGHT-click on the button and choose the Save Target As... option in the window that you get in response; save the file somewhere on your computer and then run it with your MPEG viewer.
