Mathematica - a program designed to perform calculations for the preparation of interactive documents and programming. This tool is used in scientific research, engineering analysis and simulation for training in technical schools.
Wolfram Mathematica 8 is a huge and important release with dramatic breakthroughs—and major broadening of the whole scope of Mathematica.
After 8 versions and 22 years most software systems have decayed to slow and lumbering development. But not Mathematica. In fact, with Mathematica it’s quite the opposite. As the years go by, Mathematica development is actually speeding up. Mathematica 8 introduces free-form linguistic input—a whole new way to compute. Enter plain English; get immediate results—no syntax required.
It's a new entry point into the complete Mathematica workflow, now upgraded with 500 additional functions and 7 application areas—including the world's most advanced statistics capability and state-of-the-art image processing. New workflow end points include deployment of standalone applications or interactive documents.
Numerics of any precision, symbolics, or visualization—Mathematica is the ultimate computational tool, with systemwide technology to ensure reliability, ease of use, and performance. Use Mathematica computation directly, as the engine in an infrastructure, or integrated into a standalone application.
