Across thousands of domains--with more continually added--Wolfram|Alpha uses its vast collection of algorithms and data to compute answers and generate reports for you.
Wolfram|Alpha is described as a computational knowledge engine particularly useful with mathematical and scientific information, but is also a great starting point for research into all sorts of things - historical figures, visions, etc. Ask Wolfram a mathematical, statistical, socioeconomic, physical, chemical, linguistic question, and it will compute an answer.
