This is an excellent module. It is loaded with multimedia and interactivity, and really makes great use of the Links medium. The module organization is fully developed and compliant with Project Links standards.
Page-Specific Suggestions:
The embedded-spreadsheet idea is a good one, but suffers from the following technological problems:
Possible solutions include:
This module contains two applets.
First applet: GaussSphereApplet. This applet can be seen here.
The sphere image can flicker a lot (enough to be distracting). Clipping the update area may be one way to speed up redraw.
Second applet: ElectricFieldApplet. This applet is presented on two different pages:
here
and here.
The instructions for using this applet never mention that the field coordinates are displayed in the browser's status bar. This should rectified, especially since some follow-up questions specifically ask for coordinates.
curved_concept.html:
The image gridflux.gif is much too big. The maximum size for all images in Project links modules is
500 pixels wide by 360 pixels high. This maximum may be increased in the near future, but certainly not enough to accommodate
this image's current size.
