WolframAlpha

Remember the Star Trek computer? It's finally happening–with Wolfram|Alpha. Building on 25 years of development led by Stephen Wolfram, Wolfram|Alpha has rapidly become the world's definitive source for instant expert knowledge and computation.

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.

Parts of Wolfram|Alpha are used in the Apple Siri Assistant; this app gives you access to the full power of the Wolfram|Alpha computational knowledge engine. Domains covered by Wolfram|Alpha include:
