Everyone is familiar with search engines but have you ever heard of a computational knowledge engine? A search engine looks for the best possible matches to your search words out of all of the web pages that it has indexed, but a computational knowledge engine is different. It does dynamic computations with the data it contains and comes up with calculations or facts in response to your search terms. Wolfram|Alpha is just such a computational knowledge engine, and you can use it to find and learn amazing things.
The introduction of Wolfram|Alpha defined a fundamentally new paradigm for getting knowledge and answers—not by searching the web, but by doing dynamic computations based on a vast collection of built-in data, algorithms and methods. Bringing broad, deep, expert-level knowledge to everyone… anytime, anywhere.Wolfram|Alpha
Perform all kinds of calculations and explore just about any topic you can imagine with Wolfram|Alpha. The best way to get started is to go to the main page and select a topic below the search box that interests you. From there, you will find even more specific topics. Pick one, maybe another one after that, and experiment with the example searches. You'll quickly learn how to be a Wolfram|Alpha power searcher.
Here are just a few examples of the ways you can use the Wolfram|Alpha knowledge engine.
There’s so much to explore. Have fun with it!
