Science searching

Symbolab is a new search engine designed for mathematicians and scientists. The search engine is a semantic search engine which means that rather than just searching the text of your query Symabolab attempts to interpret and search for the meaning of your query. What this means is that when you type in an equation you will get results as links and get results as graphs when appropriate. Think of it Symbolab as a cross between Google and Wolfram Alpha.
