It’s not new, and I wouldn’t say it is as good at tangling one up within the depths of the internet as Wikipedia…and it probably isn’t quite there yet on the technology side…but Wolfram|Alpha is pretty neat.
Wolfram Alpha (often stylized as 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 would. It was announced in March 2009 by Stephen Wolfram, and was released to the public on May 15, 2009. It was voted the greatest computer innovation of the year by Popular Science.
For example, I might be curious to see how long I will live.
It also has a pretty nifty nutrition calculator. Spam + one apple + vegemite will yield the following nutrition.
* full disclosure – I don’t eat Spam…or vegemite but have been known to consume apples.
