WolframAlpha is a computational, knowledge search engine and is thought by some as possibly the most likely candidate to give Google some serious competition because it can create information rather than just read/present content already on the web, which is something Google can not do. Students at all levels will love this search engine because it does work for you, for example, type in your birthday and you will be amazed at the results, or type in any mathamatical formula and get the answer. For example, type or paste this math formula x^2 sin(x) into the query box and check the computations that you get. Try it now!
