When I connect to te site, I see a list.  http://www.phy.ntnu.edu.tw/ntnujava/index.php?c=1

When I click on (for example) Kinematics, I see anpther list


I am now expecting to click on one of these links and see an applet.  Sometimes I do not get an applet, I get posts about an applet.  I can't find the applet!
