“I like to go beach-combing, and I like to find interestingly shaped rocks. When I really get into the groove I start finding beautiful rocks everywhere, until I discover that all of the rocks on the beach are beautiful. And so I try to find beauty even in the smallest moments, because beauty is something that can grow if you let it.”
― Douglas Coupland
The Eye of the Sahara, seen here in an aerial image provided by the ISS, is is a prominent circular feature in the Sahara desert near Ouadane, west–central Mauritania. It was initially thought to have been caused by a meteor impact, but lack of strong evidence has turned many off to this hypothesis. At 30 miles wide (50 km) it is easily visible from space.
We often think of raindrops as spherical or tear-shaped, but, in reality, a falling droplet’s shape can be much more complicated. Large drops are likely to break up into smaller droplets before reaching the ground. This process is shown in the collage above. The initially spherical drops on the left are exposed to a continuous horizontal jet of air, similar to the situation they would experience if falling at terminal velocity. The drops first flatten into a pancake, then billow into a shape called a bag. The bags consists of a thin liquid sheet with a thicker rim of fluid around the edge. Like a soap bubble, a bag’s surface sheet ruptures quickly, producing a spray of fine droplets as surface tension pulls the damaged sheet apart. The thicker rim survives slightly longer until the Plateau-Rayleigh instability breaks it into droplets as well. (Image credit: V. Kulkarni and P. Sojka)
