Wolfram Alpha LLC has officially launched Wolfram|Alpha. Wolfram|Alpha is the world's first computational knowledge engine, a free online service. Wolfram|Alpha draws on scientist Stephen Wolfram's work on Mathematica, a technical computing software platform, and on the discoveries he published in his book, A New Kind of Science. The long-term goal of Wolfram|Alpha is to make all systematic knowledge immediately computable and accessible to everyone. Wolfram|Alpha draws on multiple terabytes of curated data and synthesizes it into new combinations and presentations. The service answers questions, solves equations, cross-references data types, projects future behaviors, and more.
