Today an old friend sent me a link to an amazing website, Wolfram Alpha, the world's first computational knowledge engine, offered for free on the web. It is an online service developed by Wolfram Research 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 would. It's an answer engine .
This application could change the information searching habits of millions maybe billions of cybernaughts. i've now wasted/spent two hours asking it questions. You're gonna love it.
Watch the preview when you have the time and it will boggle your mind.
There are no limits to what you can do with this website...it is a "keeper!"
