Never heard about WolframAlpha? This is a new search engine but not ordinary search engine. It is a computational knowledge search engine. Instead of searching web, the result of WolframAlpha is from computations of its own knowledge base. In other words, the result is not only web and link but answer. So, this will be the main benefit of using WolframAlpha than Google.
So, let test the ability of WolframAlpha by inserting some questions.
1. Who is the president of United States?
You can see the result like this one
