air trap


a waterfall of mist flowing over golden cliffs of west bay in dorset. noted the videographer, “when i walked on to the beach i couldn’t see anything because of the fog. i could barely see the top of the cliffs. i sent up my drone well above the cliffs to see what was happening and i could see the fog just flowing over the cliffs like a waterfall. 

normally, hot air will cool as it rises, but the opposite can sometimes occur in what is known as temperature inversion, where hot air high up acts as a seal to keep cold air and fog trapped below, creating the scene of a river of fog seeming to flow into the sea below. (x)


Superhydrophobic–or water repellent–materials are much sought after. Their remarkable ability to shed water is actually mechanical in nature–not chemical. Surfaces with a highly textured microstructure, like a lotus leaf or a butterfly wing, shed water naturally because air trapped between the high points prevents the water from contacting most of the solid surface. The result is that a drop sitting on the surface will have a very high contact angle and be nearly spherical. Instead of wetting the surface and spreading out, it can slide right off, as seen in the animations above. Here researchers have treated the coins and the right half of the cardboard with a spray-on coating that creates superhydrophobic microscale roughness. Similar coatings are commercially available, but such coatings are delicate and lose their hydrophobicity over time as the microstructure breaks down.

If Eurus had trapped the Cabin Pressure crew in her cell instead of BBC Sherlock...

Martin, with his unassailable knowledge of aeroplanes, would have figured out within 30 seconds that the girl in the plane couldn’t possibly be real. 

Carolyn, who must always be top dog, would have immdiately disabled the camera and microphones in the cell, leaving Eurus powerless.

Douglas, with his brilliant ability to remain clear-headed when others are panicking, would have remembered that there is no glass in the cell, and thus they can all leave at any time. 

And if any guards tried to stop them on the way out, Arthur would simply charm, confuse or frustrate them into letting them pass. 

They’d be sailing out of Sherrinford within half an hour and be home in time for tea.  

Bubbles in amber

The amber was polished in order to reveal these dendritic air bubbles trapped between flow layers. The magnification is forty times and the image was taken in brightfield, ie with the light shining through the specimen. This image won 17th place in the 1983 Nikon small world photomicrography competition.
