WolframAlpha : The 21st Century Search Engine for educators ~ Educational Technology and Mobile Learning

WolframAlpha is a great search engine for computing answers and getting knowledge . I decided to add it to my lists of search engines that educators need to know about because of its interesting features . WolframAlpha is not , in fact , a search engine but rather a computational knowledge engine . While other search engines index web pages to look for textual matches accompanied by lists of links , WolframAlpha ‘uses built-in knowledge curated by human experts to compute on the fly a specific answer to every query .
