The Art of Science

Posted by TimSlavin at June 17, 2005

This image, called Driven, won second place in the Art of Science Competition recently held at Princeton University. Here's the what you see in this photo:

"This image illustrates evolving dynamical patterns formed during the spreading of a surface-active substance (surfactant) over a thin liquid film on a silicon wafer. After spin-coating of glycerol, small droplets of oleic acid were deposited. The usually slow spreading process was highly accelerated by the surface tension imbalance that triggered a cascade of hydrodynamic instabilities. Such surface-tension driven flow phenomena are believed to be important for the self-cleaning mechanism of the lung as well as pulmonary drug delivery."

Maybe you thought it was a lava lamp photo? Even more interesting, their site was built by Jonathan Harris of Number 27 who created two thoughtful online projects, 10x10 and Wordcount.
