What Wolfram Alpha actually is

A computational engine rather than a search box, answering maths, physics, chemistry, finance and unit questions by calculating instead of retrieving pages. Type an integral, a chemical formula, a date range or two city names and structured results come back with charts attached.

Why it is worth your time

Typing a plain-English question such as the mass of the Moon in double-decker buses returns an actual figure, which no search engine will do.
