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!

West Kennet Long Barrow a Neolithic tomb, situated on a prominent chalk ridge, near Silbury Hill, one-and-a-half miles south of Avebury, in Wiltshire.
The site was recorded by John Aubrey in the 17th century and by William Stukeley in the 18th century.
Archaeologists classify it as a chambered long barrow and one of the Severn-Cotswold tombs. It has two pairs of opposing transept chambers and a single terminal chamber used for burial. The stone burial chambers are located at one end of one of the longest barrows in Britain at 100 m: in total it is estimated that 15,700 man-hours were expended in its construction. The entrance consists of a concave forecourt with a facade made from large slabs of sarsen stones which were placed to seal entry.
The construction of the West Kennet Long Barrow commenced about 3600 BC, which is some 400 years before the first stage of Stonehenge, and it was in use until around 2500 BC. The mound has been damaged by indiscriminate digging, but archaeological excavations in 1859 and 1955-56 found at least 46 burials, ranging from babies to elderly persons. The bones were disarticulated with some of the skulls and long bones missing. It has been suggested that the bones were removed periodically for display or transported elsewhere with the blocking facade being removed and replaced each time. Recent re-analysis of the dating evidence suggests that the 46 people all died within 20 – 30 years of each other, and that the tomb was open for 1,000 years.
The latest excavations also revealed that the side chambers occur inside an exact isosceles triangle, whose height is twice the length of its base. Artefacts associated with the burials include Neolithic Grooved ware similar to that found at nearby Windmill Hill.
It is thought that this tomb was in use for as long as 1,000 years and at the end of this period the passage and chamber were filled to the roof by the Beaker people with earth and stones, among which were found pieces of Grooved ware, Peterborough ware and Beaker pottery, charcoal, bone tools, and beads. Stuart Piggott, who excavated this mixture of secondary material, suggested that it had been collected from a nearby 'mortuary enclosure' showing that the site had been used for ritual activity long after it was used for burial. The finds from the site are displayed at the Wiltshire Museum in Devizes, including some of the most impressive beakers from Britain.

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.

As we are 100% organic gardeners, the struggle with molluscs has been an almighty one this year due to all the extra rain. They have munched their way through nearly every crop and flowerbed with relentless enthusiasm and tiny ones getting primed for next year are everywhere. Garden snails are nocturnal and there's nowhere they like to spend the day more than parked up in the perfectly concave leaves of sedum spectabile. These three looked too perfect to ignore so it was a photo opportunity must. It would of course be very easy to rearrange snails to your hearts content, but these three were genuinely found in this very ordered arrangement.
Revisiting Carl Zeiss Ultron 50mm f1.8 concave version. It is legendary lens mostly appreciated for its sharpness and strange design. It is mechanical beauty too. But very often, bokeh and flare of Ultron was received with "meh".
Me, personally, I have no issues with either

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.

Little bit of winter colour in the sky late yesterday afternoon.
Just liked the shape of the landscape here, reminds me of how I used to draw hills and fields when I was a child.
