Descriptions: WolframAlpha is a computational database/search engine that interprets natural language queries, returning dynamic answers. Although still in development, it currently "...contains 10+ trillion pieces of data, 50,000+ types of algorithms and models, and linguistic capabilities for 1000+ domains." Enter a food item, and the engine generates a page of its nutritional, caloric, vitamin, mineral and physical properties. Input any integer for information about its forms, qualities and expressions. Explore a surname or given name-- view, among other data, its trend in popularity from the 1890's to the present. Input a disease name, and generate a series of graphs illustrating prevalence, average age of onset, sex distribution, medical coverage and more. Use the disease name as a cause of death, and mortality statistics are presented. Apps are now available to download for use with iPhone, iPad and Android.
