I gots my writing sandwich. I mean business.

A sandwich is placed on a green plate, featuring ham and string potatoe chips inside a partially opened bread roll. In the background, there are framed photos and a small decorative item on a wooden table.

This capture made extensive use of view camera tilt movements. The depth of field is quite shallow here, so the lens was tilted forward to keep the stems and leaves in focus from the front to the back.

Captured with a Sinar P camera. a 240mm/5.6 APO Symmar lens, and a BetterLight scanning digital back.

This is a minimalist studio still life, so it's all about lighting and geometry.

Illuminated by a single hard light placed at the left of the frame, yielding well defined shadows. The background was a white sweep table, creating the illusion of an infinite background. The fruit looks evenly spaced, but actually the rear one had to be much farther back than the center one to create that effect.

I'm struggling to become more like myself. So I was happy to read that Agatha Christie wrote:

"As life goes on, however, it becomes tiring to keep up the character you invented for yourself, and so you relapse into individuality and become more like yourself every day. This is sometimes disconcerting for those around you, but a great relief to the person concerned."

Here’s a new poem called ‘Wild Weekend’.

Wild Weekend   Sunday – and the squirrels are lazing in their branches, the sheep are congregating for morning service, and the bears are sleeping off their sore heads.   The sloths are taking things slow, the hippos are wallowing, the cats are curling up on the newspaper in front of the television. The alpacas will spend the day in their fluffies.   Not everyone is taking it easy. The deer are up already for a walk around the park. The ducks are planning a trip across the lake. The salmon have gone wild swimming.   The snails are pottering about the garden, while the crows scan its aisles for materials and a spot of DIY. The pigeons have split up: some are hanging around the shopping centre,   others intend to spend the afternoon at the Test match. The lions are having an old friend over for dinner, the camels are baking, the spiders are browsing their webs, and the humans…   the humans are wondering where the weekend has gone as they stave off the prospect of another beastly Monday, questioning the natural order of things.   Brian Bilston

Thanks to Noether, we now know that in classical mechanics, conserved quantities come from symmetries. For a planet orbiting the Sun, conservation of energy comes from time translation symmetry. Conservation of the angular momentum comes from rotation symmetry. But there's another, more mysterious conserved quantity: the eccentricity vector, which points along the long axis of the planet's elliptical orbit.

What symmetry gives *this* conserved quantity?

Symmetry under rotations in 4-dimensional space! These include the obvious rotations in 3-dimensional space which give angular momentum. The other 4-dimensional rotations act in a much less obvious way, and give the eccentricity vector.

But how does the 4th dimension get into the game?

In this article, I explain how a planet orbiting the Sun is secretly isomorphic to a particle moving around on a sphere in 4-dimensional space. This is a nice explanation of the 4-dimensional rotation symmetry.

But the planet is also isomorphic to a *massless* particle moving at the speed of light on a sphere in 4-dimensional space! This brings relativity into the story, and sets the stage for still more shocking developments.

There's a vibe coding thread where developers are having an epiphany: maybe they should keep old versions of their code around, just in case their latest inspired hack turns everything into digital spaghetti.

Congratulations—they've just discovered their first professional software delivery practice: Version control. That's from 1972.

Next week, they'll revolutionize development by inventing "testing" after their app crashes in production. Again.

Tidal locking

results in the Moon rotating about its axis in about the same time it takes to orbit the Earth. Except for libration effects, this results in it keeping the same face turned towards the Earth, as seen in the figure on the upper left. (The Moon is shown in polar view, and is not drawn to scale.)

+ Upper left:
> If the Moon didn't spin at all, then it would alternately show its near and far sides to the Earth while moving around our planet in orbit.
