Conrad Wolfram presents an interesting argument for the way to teach Math.

"Enter your question or calculation and Wolfram|Alpha uses its built-in algorithms and a growing collection of data to compute the answer."

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.

MathWorld is the web's most extensive mathematical resource, provided as a free service to the world's mathematics and internet communities as part of a commitment to education and educational outreach by Wolfram Research, makers of Mathematica.

"Wolfram|Alpha is a free online computational knowledge engine that generates answers to questions in real time by doing computations on its own vast internal knowledge base. Our long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. This can be valuable to educators in many ways. "

"Wolfram Alpha is on a mission to develop an "app for every course." The company launched its first three subject-specific iPhone apps on Tuesday, and all three - Algebra, Calculus, and Music Theory - look to be promising educational tools."

Create music tracks with Wolfram. Change instrumentation, tempo, pitch.

"A free resource of interactive visualizations, from elementary education to the frontiers of research."

Search both engines side by side. Great to compare how these search engines work.
