As someone interested in both Science and Technology, I need to mention Wolfram|Alpha. It looks sort of like a search engine, but it's more like a calculator. Their stated goal is "to make all systematic knowledge immediately computable and accessible to everyone." Basically they want to collect data and algorithms in order to have a system that answers questions.
It's obviously a work in progress, but what they have accomplished already is pretty cool. They have some example queries that you can try in order to get a feel for how it works. I think that Educators in particular should be very excited about the possibilities.
