Wolfram|Alpha answers life’s tough questions
The new Wolfram|Alpha “computational knowledge engine” is the coolest thing I’ve seen in a long while. My first impression was that this was just a big fancy calculator to help people solve NP-complete problems and complex differential equations and whatnot. Not that this wouldn’t be impressive in its own right, but it’s not exactly something I would use (though I could have used it back in college, when I was smart). The really cool thing about Worlfram|Alpha, though, is that it has a myriad of possible uses.
