Catastrophe Theory or as it's now known. Qualitative Dynamics and the Mathematical Theory of Dynamical Systems
Mesocyclone, centerpiece of the Turbulent Landscapes exhibition, is a 40 foot tall, working model of a hurricane. Powerful fans at the base of the structure create complex airflow patterns. These patterns are made visible by water vapor released from the top of the structure. Untried ever before at this scale, mesocyclone was a major engineering and design challenge for the Turbulent Landscapes team. The exhibit continues to mesmerize museum visitors, often from quite far away!
