The bird one is so odd. A strange mix.
Everyday. We are going to post food for our eyes everyday. Good eye food. From good eyes.

The first annual art of science exhibit at princeton. This image is the wake created by a plate pitching back and forth. Quite beautiful.

This unique semi-organic mineral structure is the result of a slow chemical reaction. The reaction occurs spontaneously between alkanethiols, which are simple sulfur-containing organic compounds, and lead oxide. Here, the oxide is a surface coating on a coil of metallic lead wire that forms naturally in moist air. The structure consists of layers of lead alkanethiolates, a stable compound that is solid at room temperature and has a distinct yellow color. The layers grow outwards from the surface of the wire as the reaction proceeds, curling into “petals.” But be careful, beautiful though it may be, this “flower” is toxic. The structure grows slowly upward as the wire is uncoiled by the growing petals, eventually filling the jar in which the reaction occurs. This structure took more than a week to grow. A less delicate but faster growing form of this material can be used to remove polluting sulfur compounds from gasoline during the refining process.

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.
