Thank you to the people who have informed me that many of these applets are no longer working. There seems to be some problem with the newer versions of the Java Runtime Environment that prevents some of these applets from working.
I am in the process of fixing the issue. Several applets should now be working, including
Fusion in the Sun,
1 over R squared,
If you have an applet that you need to use, please let me know and I'll try to get it working again.

These Java applets were written when I was working for the Physics and Astronomy Department at the University of British Columbia.
