Wolfram Alpha is like a cross between a research library, a graphing calculator, and a search engine. But does Wolfram Research's "computational knowledge engine," set to debut publicly later this month, live up to its hype as a Web site that Google needs to be afraid of? Wolfram Alpha creator Stephen Wolfram on Tuesday gave a demo of the service to a crowd of online reporters. Few have access to the private test version of the service itself, but we got access Monday night. We found it compelling, if limited. We're eager to see this site develop. It does things with online information that Google does not. Here are our impressions of the current version of Wolfram Alpha.
The GeoEye-1 satellite whizzes in low-Earth orbit, but when will it be taking photos over you? Alpha will show you on a map, in this case a 3D view of the globe that shows the satellite above Antarctica. It'll also tell you the satellite's 16,812-mph average velocity, its 428.4-mile altitude, and 98-minute orbital period. Photo by Stephen Shankland/CNET Caption by Stephen Shankland

Do you have dozens of PDF files from your favorite scientific articles scattered on your harddrive? Do you also try to desperately organize them by renaming and archiving them in folders? But like the piles of printed articles on your desk, you can't keep up with all the new papers you download, and despite all your efforts it has become impossible to find that one article.
Search for articles using the built in search engines, retrieve and archive PDFs, and read and study them all from within Papers, your personal library of Science.

A. Newell, and H. Simon. Communications of the ACM, 19 (3):
113-126(March 1976)p. 116:
"The Physical Symbol System Hypothesis. A physical
symbol system has the necessary and sufficient
means for general intelligent action."
p. 120:
"Heuristic Search Hypothesis. The solutions to
problems are represented as symbol structures.
A physical symbol system exercises its intelligence
in problem solving by search--that is, by
generating and progressively modifying symbol
structures until it produces a solution structure."
p. 121:
"To state a problem is to designate (1) a test
for a class of symbol structures (solutions of the
problem), and (2) a generator of symbol structures
(potential solutions). To solve a problem is
to generate a structure, using (2), that satisfies
the test of (1).".
