Double Eclipse! Or Why Carbondale, Illinois, Is Special
The upcoming August 21, 2017, total solar eclipse is a fascinating event in its own right.

Their methodology—hanging a cardboard cutout of the lower 48 states at two (...)
Announcing SystemModeler 5: Symbolic Parametric Simulation, Modular Reconfigurability and 200 New Built-in Components
Our goal with SystemModeler is to provide a state-of-the-art environment for modeling, simulation—and analytics—that leverages the Wolfram technology stack and builds on the Modelica standard for systems description (that we helped to develop). SystemModeler is routinely used by the world’s (...)
