Wolf Ram Alpha is a computational search engine geared toward science and technology stuff. For example, I looked up, "sin^2(x)+cos^2(x)" which is a Trigonometry Identity (actually it’s sin^2(x)+cos^2(x) = 1), and it returned me with a nice graph, alternate representations and so on.



Cool results...

At the bottom of the result, they also have the feature to save the results as a .pdf file. Really cool feature that other search engines lack.

Then I looked up Calculus, just to check if it gives any kind of result like the traditional search engines. However, it actually suggested different topics directly related to calculus.


elevant Topics

To dig a little further, I looked up "fuel usage 800 miles, 27 mpg" and the results really surprised me. Even Wikipedia doesn’t give you information like below:


Transportation results...

Overall, I don’t think it’s actually a threat to any of the traditional search engines, but another cool resource to aid you in your research.
