Wolfram/Alpha is to be the first web-based tool that can find answers to all systematic knowledge in the world. For educators, this "computational iknowledge engine" can find objective and fact-based answers for a variety of subject areas. Type in "Newton's Law," for example, and the formula for force is explained. Enter in an equation for a line, and the site plots the line on a graph. Ask "What is the GDP of the United States and Canada?" and a chart depicts a side-byside comparison of the nations' economic data.
