If you're doing anything technical, think Mathematica--not just for computation, but for modeling, simulation, visualization, development, documentation, and deployment.

Why Mathematica? Because this one integrated system delivers unprecedented workflow, coherence, reliability, and innovation. Rather than different toolkits for different jobs, Mathematica has been built ground-up over nearly 20 years to deliver one vision: the ultimate technical application and environment.
