Wolfram|Alpha is an answer engine developed by Wolfram Research. It is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer as a search engine might.
According wikipedia, Wolfram|Alpha is written in 5 million lines of Mathematica (using webMathematica and gridMathematica) code and runs on 10,000 CPUs!
Wolfram is really powerful. Only disadvantage being, to get most of the it, you’ll have learn the pre defined queries. This is not necessary, however if you know them you’ll have the results right in front of you. Here i’ll show you some of the predefined queries that you can use with Wolfram alpha.
First lets start with my favorite query. IP trace back. Suppose you have an IP and you wanted to know which country it belongs to or where it is located. Just type that IP into Wolfram Alpha, it will give you where it belongs to. Cool isn’t it ? Check it out in action
The following are some predifined queries. Left side describes the query and right one is the actual query. You’ll need to enter this in Wolfram alpha to get results.
