Wolfram/Alpha

[blogger789]

The website, Wolfram Alpha, launches later this month, and aims to provide a different approach to internet search queries by not only understanding people’s questions but answering them directly. It means web users can ask questions online in much the same way as they ask them in real life, a process known as “natural search”. 

Some internet experts have dubbed Wolfram Alpha as “as important as Google”. The search engine is the brainchild of Stephen Wolfram, an eminent British physicist.
