The Web site www.wolframalpha.com offers engineers a computational knowledge engine developed by Stephen Wolfram, a U.K. physicist. Hosted by Wolfram-Alpha, the engine searches its own database for answers to questions. The database is built on Wolfram Mathematica, which is a computation and visualization system, development environment and deployment engine that uses the latest Web and parallel computing technologies. Equally important, the database puts information into context and performs any needed calculations.
