I stumbled across this search engine and thought it was pretty cool. I think it may be my new favorite.... It doesn't just search through indexed websites, but treats each search as a computation. The results of that computation are presented in a consistent format. Whether seaching for information on a particular location (city, state, etc.), measurement conversions, solving for a variable in a mathematic equation, or mapping logic circuits, I've been impressed by the results! There were some examples on the homepage of other things it could do, but I haven't tried them all out yet. This would have been a handy tool in high school and college for research projects!
