This is such a lovely, clear image - fantastic detail 🙂
Hookland was made by Soviet science fiction and cosmonauts. It was made by pulp novels my mother didn’t want me to read, but that my Aunt Barbara still lent me. Made by countless bad films surreptitiously watched on an old black and white TV. It has been shaped by a refusal to sneer at the work of Stephen King because Salem’s Lot was brilliant when I read it at 11 and still is. In fact, it has been shaped by a refusal to sneer at anything that generated a sense of sublime, awe and terror in childhood – even being forced to perform interpretive dance to Tomita. It has been made by brilliant writers – Aickman, Machen, Jackson – and it has been made by bad ones. It owes large debts to comics, goth, punk and movie soundtracks that is will never repay. Its substitute parents are free public libraries and Radio 4. It comes with a childhood place soaked with fear of ghosts and UFOs, it comes from a place of love for those exact same engines of terror. It comes from a revulsion for how psychogeography has increasingly became an academic and art language that excludes people from their own primal experience of landscape. It comes for a raging dislike of commodity writing about place and nature. It comes from an absolute refusal to allow fascists to easily occupy their cherished grounds of myth and folklore. It comes from the cunning, the ghost soil, the landscape of England as experienced by this broken body for five long decades. It comes from being a Fully-grown Changeling. Fay Godwin, Paul Nash and Dame Laura Knight are always muttering about it with disapproval in the imagined afterlife. Nothing in it is made up, just remembered differently. It was designed to be a permissive space, a common ground where people could explore and find their own hauntings. You all own it, you all make it. You are all marching with the spirits of dead spaceman, wood sprites and a thousand lost childhoods. You are all scuffling up your memories, your own stories as you navigate across th…

This black-and-white studio portrait photograph captures Rosalind Elsie Franklin, the brilliant British chemist and X-ray crystallographer whose meticulous research produced Photograph 51—the iconic X-ray diffraction image that revealed DNA’s double-helix structure and proved pivotal to the 1953 Watson-Crick model of the molecule. Shown in a close-up, three-quarter view from the shoulders up, Franklin appears in her late twenties or early thirties, her dark, wavy hair neatly styled and swept back from her face. She wears a simple, dark collared blouse or shirt with a crisp, professional appearance that reflects the understated elegance typical of mid-20th-century scientific women. Her expression is calm and intensely focused: direct gaze slightly off-camera to the viewer’s left, lips gently closed in a subtle, knowing half-smile, conveying quiet confidence, intellectual depth, and quiet determination. The plain, softly lit studio background with its neutral gradient emphasizes her face and upper torso, creating an intimate, timeless composition that places her poised presence at the absolute center.
Chemist & X-ray crystallographer Rosalind Franklin's meticulous research was instrumental in uncovering DNA's molecular structure.
Most famous for her role in the DNA double helix discovery, her work also revolutionized our understanding of viruses & coal. Died #OTD in 1958, age 37. #WomenInSTEM
Abundant Eocene fossils of plants and animals are found in the Green River Formation of Wyoming, Colorado and Utah. This fossil Pseudosalix Hanleyi, with stems, leaves and flowers preserved, is harder to find than a T-rex tooth!

Place is layers of story. No matter how wide the field, how sweeping the sky, it will always ghost-soaked. For this is the inevitability of place and us, we cannot help but plant our ghosts in it. – Dr. M. Benn, presentation at the 1982 Woden College Ghost Conference
one of the hardest science topics is explaining to a modern person that in the 1800s geologists were more popular than streamers are today books exploring topics like the history of a rock were doing multimillion print runs, & guys giving talks on igneous vs metamorphic were filling sports stadiums
Your Bretwalda is pleased to announce that two new Border Collie pups have been purchased for the herding of Wülferhampton's flocks.
A competition to name them (both girls) will be held shortly.

#FossilFriday Among the Cretaceous gastropods and rudist bivalves in the floor tiles at the Le Shuttle terminal in Folkestone are some branching fossils that resemble bryozoans but are more likely to be sponges.

It is truly remarkable that after the Vietnam War, after the Afghanistan War, after a catalogue of US military failures in the post 1945 world, people claiming to be serious analysts are saying because the US dropped alot of bombs it won this war.
It did not.
Money is worthless and nobody owns anything.
This is a fact.
A revolution simply makes it real.

On this day in Wyrd Britain history...
1960 - 'Circus of Horrors' is released by AIP.
1991 - Massive Attack released their debut album, 'Blue Lines'.
2005 - Coil released '...And the Ambulance Died in His Arms', a recording of their performance at All Tommorrow's Parties on the 4/4/03.
Some relief in the terrible turmoil of the world this morning. In this place that has seen protest (& just 3 miles from Greenham Common & those refreshed memories of nuclear war) we hold on to the things we love, the people, the places, the peace.

We must not become less of ourselves in the face of annihilation. We must hold to who we are, hold tight to our joys. i came into this world dead, grey and silent. I shall go out of strange, full of love and wondrous curiosity. I shall go a fully-grown changeling with a kiss of intent on my lips.

Headline looks good though - I wonder how much money we have spent on student loans never to be repaid - and where has the money come from?
