Wolfram|Alpha

Quite simply, I think this is one of the greatest advances in library science and computing in recent memory. This isn’t just a toy or a search engine, this is a knowledge processor that makes any factual data in its system instantly computable.

If you are a teacher or scientist, you need to be paying attention to this. In fact, if you are a human being who is engaged with any sort of data, you need to be paying attention to this as well, because while Wolfram|Alpha may not live forever, this advance, as well as any of its inevitable successors, are the future of information computing.
