It’s a curious—and unintentional—juxtaposition. Because in a sense NKS is the intellectual structure that’s now making Wolfram|Alpha possible. And Wolfram|Alpha is the first “killer app” of NKS.
Stephen Wolfram has written a blog today that reports on the state of NKS and explains a little bit of that connection.
Building the ultimate computational knowledge engine is a highly ambitious and long-term project. The Wolfram|Alpha that you will get to start exploring next week is really just the beginning. Still, there are a lot of ways that you might use Wolfram|Alpha.
In this screencast, Stephen Wolfram gives a quick introduction and demo of today’s Wolfram|Alpha.
