Happy Winter Solstice!

Beer can, pinhole camera photos of the Summer to Winter Solstice (2024) and the Winter to Summer Solstice (2025).

You never know quite what you're going to get with these photos, set the beer can pointing towards the sun at hopefully the correct angle and wait 6 months!
A pinhole camera photo taken from Summer to Winter Solstice. It's a bit blurry as the aperture was made with a tiny needle and no focus mechanism. There are yellow to green lines across the photo, that's the Sun moving across the sky over the course of a day. The top line is from the Summer Solstice, the bottom line from the Winter Solstice. Cloudy days don't have any lines or broken lines as the Sun was obscured by clouds. There are some trees on the left, right and in the background. A pinhole camera photo, a 6 month exposure from Summer to Winter solstice. There are trees on the right side and background. A house with two cars in the drive are visible almost in the center of the photo. The lines are made from the Sun moving across the sky with the bottom line being the Winter Solstice and the top line the Summer solstice. On cloudy days the lines are broken or not visible as the sun was obscured by clouds. The lines show some reflections from a tree trunk. The lines are mostly a white color with some hints of blue, green and yellow in places. Some of the colors could be from rain or snow staining the paper I was using. A solargram/pinhold camera photo taken from the Winter Solstice of 2024 (21 Dec) to Summer Solstice of 2025 (20 June). It's a 6 month long exposure taken with a beer can pinhole camera, it shows the sun's movement across the sky during that time period, each day the Sun scribes a line on the paper in the pinhole camera. The bottom line is Dec 21 2024 and the top line is 20 June 2025. This kind of photo makes the movement of the Sun during the day into visible trails on the paper in the camera. There is a long orange-yellow arc going across the paper showing the whole 6 months. There is a shadow of my tree on the image, the tree blossomed during the exposure. Shades of blue and pink are on the paper too. There is a black kind of semi circle at the top of the image, that's where the water was disintegrating the top part of the paper.

[1/8] L’histoire commence dans un pub d’Oxford, où une discussion entre George Monbiot et des chercheurs révèle un paradoxe. Les sols nourrissent 99% de l’humanité, mais restent largement méconnus. Cette prise de conscience ouvre la voie à un outil sismique capable de révéler leur structure intime.
Over a pint in Oxford, we may have stumbled upon the holy grail of agriculture | George Monbiot
I knew that a revolution in our understanding of soil could change the world. Then came a eureka moment – and the birth of the Earth Rover Program, says Guardian columnist George Monbiot

Peupliers dans la brume
Alignements de peupliers dénudés se dressent comme des silhouettes effilées dans le paysage. La brume se lève doucement au ras du sol, voilant les troncs les plus lointains. Au-dessus, un ciel bleu s’éclaire du soleil levant sur la droite, tandis qu’au fond, le panache de la centrale nucléaire de Nogent-sur-Seine s’élève dans l’air froid du matin.

Plus sérieusement comment expliquer qu’on ne peut plus se référer à un climat qui n’existe plus pour aménager les territoires. On fabrique au mieux des actifs échoués. Au pire un futur catastrophique. C’est terrible de parler sans être entendu.

Ryan Moulton @moultano Oil is the most Lovecraftian thing that actually exists. You're telling me that there's a black ichor under the earth, made from the ancient dead, whose burning can realize all the dreams of man but only at the price of slowly returning the earth to its primordial state?

This is horrifying, but I’m glad the Wikipedians are safe. It could have been far worse, given that the MAGA fascists have been trying to incite violence against Wikipedia editors, and trumpists are defenders of pedophiles like the gunman. gothamist.com/news/gunman-...

As a primatologist, Jane Goodall was a huge inspiration to me. I admired the way she describes chimpanzee behavior with such detail and empathy, and she’s inspired so many people and advocated for chimpanzee conservation and welfare.

However, I'm dismayed at what her narrative leaves out (1/10)

RIP #JaneGoodall - one of the modern pioneers of profound interconnections between people, animals and ecosystems. Her life was lived through science, compassion and tireless advocacy for the multiple values of nature - leaving a legacy that will endure for people and planet.

Tipping points are moments when a gradual change leads to a forceful, surprising shift in a system. They show up in chemical reactions, electronics, cells and — potentially catastrophically — in Earth’s climate. What can they tell us, and what can’t they?

Tipping points in our climate predictions are both wildly dramatic and wildly uncertain. Can mathematicians make them useful?
