2005 Art of Science Exhibition at Princeton

From Princeton University:

“[W]e asked the Princeton University community to submit imagery produced in the course of research or incorporating tools and concepts from science. The response was overwhelming: more than 200 entries from nearly 100 individuals in 15 departments. We selected 55 of these works to appear in the 2005 Art of Science Exhibition.”

One piece in the exhibit.

Manifold “A tornado ripping through the atmosphere is easy to identify, but in a mathematical sense, what velocity information is needed and how can we identify where the vortex begins and where it ends? A new method to do this involves following particle trajectories and investigating where the distances between trajectories stretch. This image shows some results of that work. We look at a very chaotic, periodic velocity field, named the ABC flow after its developers. We integrate trajectories both forward and backward in time, and observe the maximum stretching that occurs. The panels in the picture represent two-dimensional cuts through the three-dimensional velocity field.”
