Making the world's knowledge computable
Today's Wolfram|Alpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable
by anyone. Enter your question or calculation,
and Wolfram|Alpha uses its built-in algorithms
and a growing collection of data to compute the
answer. Based on a new kind of knowledge-
based computing
