Here is a fun fact for you to try, the makers of the movie, "The Matrix", got right. Look into the concave side of a spoon, and you will see yourself both inverted and upside down. Then turn the spoon over, and look at the convex side. You will see yourself stretched, but right side up, and proper.
Isn't science fun!

More from the interior of the Friedrichswerdersche Kirche (Friedrichswerder Church) in Berlin's historical Mitte district. This time, it's a slightly more conventional "looking up" fisheye scene.
The Friedrichswerder Church was the first church in Berlin to be built in the Neo-Gothic style. It was designed and built by Friedrich Karl Schinkel (born 1781 in Neuruppin, a small town about 60 km north of Berlin, died 1841 in Berlin), one of Germany's most renowned architects of that era. Schinkel is best known for his neoclassical and neogothic building style. He was also a city planner, painter, and historic preserver. The main body of his work is on view in Berlin.
Built between 1824 and 1831, the Friedrichswerder Church was first reconstructed from 1982 to 1987. The latest reconstruction, necessary because of nearby construction works that destabilised the building, was between 2013 and 2019, and the church reopened in 2020. It now houses a part of the Old National Gallery's (Alte Nationalgalerie) sculpture collection.
Happy Weekend, dear Flickr friends!
I love the contrasting geometry of this location in this light. This oasis is situated in a vast, mostly treeless swathe of Scottish mountain and moorland. A place where you wander forever in limbo between light and dark searching for that elusive balance.
'Dolines' are concave indents into a limestone plateau. The indent comes from the chain reaction of a collapsed cavern deep underground. Fine sediments congregate and they can be more fertile that surrounding thin soils, apt for animal pens or croft agriculture. The above is known as a lavogne and is a concave disc from the greater theme of stone walls. Were the first lavogne tweaked dolines? Normally the above disc should be full of water for herds of the sheep and goats that go on to make the cheeses so well known on the Larzac. This year there were three heatwaves. This example still had a disc for reflection; others were dry. Lavogne are relatively easy to see in areas such as the Larzac, Causse Méjean, Causse Noire... Normally an 'abreuvoir' (water trough) is fed by a spring or hand pulled from a well. Here the lavogne is vast and open air. Some lavogne key into a surface junction between rock layers and these are not circular and may be precursors for a second method of conserving water on a limestone plateau, the 'toit-citerne'. The example of open-air asymmetrical lavogne in Saint-André-de-Vézines is thought to be one of the oldest examples and couples as a lavoire. I would hazard against dating just such structures and expect a deep history and indeed prehistory of local needs and superpositions.

This isn't a new species for me, but an improved shot for my prairie bee and wasp species set. It has a confirmed INaturalist ID.
Cuckoo bees typically enter the nests of pollen-collecting species, and lay their eggs in cells provisioned by the host bee (in this case a longhorn bee). When the cuckoo bee larva hatches it consumes the host larva's pollen ball, and, if the female kleptoparasite has not already done so, kills and eats the host larva.

This was captured during a delightful walk along the beach. The banks and large flakes of yellow-coloured foam are a natural phenomenon. These are the remains of dead algae, specifically the species ‘phaeocystis globosa’, generally called foam algae or brown slime algae. The wave action whips these remains into foam.
