Steve Wolfram wrote today in a blog post, Wolfram|Alpha Is Launching: Made Possible by Mathematica, on its relation to Mathematica.
“Wolfram|Alpha defines a new direction in computing—that would have simply not have been possible without Mathematica, and that in time will add some remarkable new dimensions to Mathematica itself. In terms of technology, Wolfram|Alpha is a uniquely complex software system, which has been entirely developed and deployed with Mathematica and Mathematica technologies. … When we launch Wolfram|Alpha this weekend, it will be running Mathematica on about 10,000 processor cores, using gridMathematica-based parallelism. And every single query that comes into the system will be served with webMathematica.”
And now, for a real test…
