Wolfram Demonstrations Updated

The announcement of an update to Wolfram Demonstrations (one of my favorite sites for supporting science instruction) arrived in my inbox yesterday. The site has been updated (in conjunction with the release of the new version of Mathematica).

To use the demonstrations now requires the download and installation of CDF (computable document format) viewer, and then the demonstrations can be viewed in your web browser. The Mac version that I installed was big (almost 600 MB), but the ease of use is worth the time and effort for the install.
