I've updated my Hewitt Drew It! screencast index page. The following sections are fully connected (or as connected as they can be):
PROPERTIES OF MATTER
ELECTRICITY AND MAGNETISM
Here's the page:
Hewitt Drew It! Screencast Index
I still need to connect the HEAT pages to their screencasts. Screencasts for ATOMIC AND NUCLEAR PHYSICS and RELATIVITY are still in production, as are some of the screencasts for LIGHT. There are already more than 100 Hewitt Drew It! physics screencasts in the wind.
Stay tuned for more!
