While not a traditional Web search engine, a challenger to Google emerged on Friday “WolframAlpha”. Unlike Google, which takes a query and uses algorithms to scour the Web and return a series of links to relevant websites, WolframAlpha.com takes a query and crunches through its databases to return answers. "The basic idea of WolframAlpha is very simple," the 49-year-old Wolfram said in an online presentation of his venture, which went live for a test run on Friday. "You type your input, your question and WolframAlpha produces a result," reports Yahoo News.
