An interesting snapshot; see the full article for details
Last week, as physicist Stephen Wolfram was demonstrating his new Web-based "computation engine"--Wolfram Alpha--to the public, Google announced a data-centric service of its own. Alpha accesses databases that are maintained by Wolfram Research, or licensed from others, and deploys formulas and algorithms to compute answers for searchers.
Using some prelaunch log-in credentials provided by the Wolfram team, I decided to run my own Wolfram Alpha versus Google test. I used a handful of search terms that could produce data-centric answers and tried variations in a few cases to see what might happen.
