Wolfram Alpha is finally the computer we were waiting for. Not only does it compute mathematical problems really fast, but it tries to give us everything about the answer, that we would like to find out. It’s like a wikipedia – just with more accurate information. Also, WolframAlpha is able to interpret user input and find out what the user is trying to find out by searching for the terms of a query in a semantic database: Weather in Guatemala, President in Germany or C6H6O.

Below the answer set that WolframAlpha delivers, there is the option for an output as pdf-file and a rather general information of where the information came from.
