Wolfram Alpha, Computational Knowledge Engine

After using a new web browser, now I want to share about a new search engine, Wolfram Alpha. Or it is more approriate if we call it, a computational knowledge engine.

Actually, like his name, Wolfram Aplpha is designed to solve a knowledge question. It best solve nearly any mathematical equation.

For example, when you enter a series of numbers, such as 2, 4, 6, 8 in the search box, in seconds, some possible answer appears...
Look at the picture I've shoot...





The answers the search engine gave, almost complete, from genetaring function, statistics, until the chart.

Another example, when you entry a question about, who is president of indonesia, the answer will looks like this...





You can use it to solve some arithmatic function. You enter your question or calculation, and Wolfram|Alpha uses its built-in algorithms and growing collection of data to compute the answer.
