This website was recently unveiled by genius British mathematician Stephen Wolfram, who came up with an algorithm to give answers to factual questions harnessing all the knowledge of the Internet. For instance, ask WolframAlpha “Who was president of Brazil in 1923?” or “What is the GDP of France?” and instead of providing websites with examples of the words used in your search like Google, WolframAlpha is able to give you a definitive answer—often with graphs, charts, and other useful information.
