MathWorld
Major enhancements have been made to MathWorld, the web's most extensive mathematics resource, which now features interactive webMathematica-powered calculators and graphs, dynamic 3D visualization tools, colorful animations, and more. Complementing these additions to the main site, the MathWorld Classroom is also newly online, providing quick introductions to topics in algebra, geometry, trigonometry, statistics, precalculus, calculus, number theory, and all other high school math courses. Visit MathWorld at mathworld.wolfram.com.

Wolfram Notebook Indexer for Spotlight and Google Desktop Search
Wolfram Notebook Indexer is now available for Mac OS X 10.4 Tiger's Spotlight and as a free public beta for Google Desktop Search. This new plug-in, included with Mathematica 5.2, lets users perform text searches of all Wolfram notebook (.nb) documents on their local hard drives, including those that are a part of Mathematica's online help system. Download the Google Desktop Search plug-in at library.wolfram.com/infocenter/Utilities/5596 or the Spotlight plug-in at library.wolfram.com/infocenter/Utilities/5614.

Wolfram Teacher Network
High school teachers in math and science can sign up now to join the Wolfram Teacher Network, a newly expanded free educational resource built around the guidance of Mathematica mentors. The program offers experienced and expert advice to teachers who want to push the limits of traditional classroom learning with Mathematica. The Wolfram Teacher Network is also looking for more Mathematica mentors, and all teachers who share an enthusiasm for Mathematica are encouraged to apply. For more information, go to www.wolfram.com/precollege/network.

Wiki-webMathematica
Luc Barthelet, senior vice president at Electronic Arts and general manager for Maxis during the development of The Sims video games, has launched Wiki-webMathematica, a new online Mathematica user forum that utilizes the power of webMathematica with the freedom of the wiki user interface. It supplements MathGroup (forums.wolfram.com/mathgroup) by allowing Mathematica users to add and edit content--including their notebooks, which are properly displayed online.
