A snow-covered stainless steel and glass shelf has a note, written in red marker, cello-taped to one of the steel supports: ‘A DONNER’.

Now a park, the Place Marie Janson – colloquially called Carré Moscou or Carré Monnaies – used to house L’Hôtel des Monnaies/het Munthof. For a century, the coins of some twenty-two countries were minted in this building.

July. Our eight-month-old son has a fever. We have a hard time getting him to drink enough. The tally marks on the back of a tortellini-box keep track of the diapers he wets and the millilitres of milk and electrolytes he’s able to hold down. 
Stuck inside with worrying parents, a sticker-book about a farm is his brother’s favourite pass-time. Tired of having to go back and forth between the pastures and the sticker-filled sheets we decide to use my arm as a repository for animals that share a habitat.

A malfunctioning of the camera leading to a double-exposed negative. The car is decisive in establishing the relationship between the superimposed photographs. In the middle of the image, we see it parked in front of the house. Slightly less visible is the same car, repeated but further away. This makes it possible to deduce that the dark outline of the house, with the roof and the chimney, is also the same house as in the other photograph. This time, the house is photographed relatively frontally (the slightly angled point of view allows to bring the shed at the back of the house in the line of sight), and from nearby. At the bottom left, the lines that make up the street help to see the continuity of the one photograph, while the electric wires at the top right aid to comprehend the other one. 

The camera malfunction speculates on a future addition to the plot. The dark, outlined shed’s scale is realistic with regards to the scale of the house and itself (the shed) in the other photograph. Its position with regards to the other buildings seems logical. It imposes itself as a possible second shed for the owner to build in the next few years. In that future shed, the car, now standing in front of the house, could be comfortably parked.

The scientific exactitude sought for in the Iconographie de la Salpêtrière and the Nouvelle Iconographie de la Salpêtrière, the (in)famous scientific publications stemming from Paris’ psychiatric hospital La Salpêtrière (1876-1918), lead to an abundance of photographic images in their pages. The photographs’ ideal: ‘Trace incontestable, incontestablement fidèle, durable, transmissible’.¹ The ambition of exactitude results in cold, and often cruel depictions of patients. In the digitized version of the Sorbonne library’s copies, some photographs have left an imprint on the opposite page. The knee of Charles, ‘le géant’, adds an unwanted layer upon its measures on the opposite page, while the photograph of the knee itself loses ink.²

The architect’s photographic archive contains seven images that can be labelled as panoramic pictures. However, they only appear as such when the photographs are viewed in the archive, as strips of negatives. In order to see the panoramic construct, the viewer needs to be presented with two consecutive negatives. 

There are two kinds of panorama in the archive: the kind that can only be attributed to a kind of laziness or a need for efficiency on behalf of the architect, and another that originates from frugality. 

The former type of panorama is created when the architect is documenting the situation as it is: it is compulsory to document the context of the building or lot, as part of a building application. He simply pivots from left to right, capturing the first and second photograph consecutively. On the filmstrip a panorama appears. 

The other kind of panoramic picture only appears at the end of the film role. The last negative on the film has been exposed (the twenty-fourth or thirty-sixth), after which he exerts force onto the lever to move the film forward anyway. Some films are known to have, by accident, a twenty-fifth or a thirty-seventh negative. The plastic between the sprocket holes tears and the film does not advance enough. The result differs fundamentally from the other kind of panorama: there is no separation, no void between the negatives. Rather, there is a slight overlap. A thin, vertical strip of film that has been exposed twice, suggesting contiguity that might not be there. The two exposures might be from altogether different sites, creating a new situation.

It is said that ‘if a space traveller were unfortunate enough to enter the atmosphere of one of the giant planets [such as Neptune], he or she would not find a single solid surface. Instead, as he or she descended into the planet, our traveller would find that the temperature, pressure, and density would all continue to increase smoothly, with no sharp transitions. Assuming that he or she was adequately protected from the temperature, pressure, and radiation, our traveller would eventually “float” at that level in the atmosphere where the surrounding density and his or her own density were equal.’¹ 

It is said that it storms on Neptune.
Violently.
1200 mph. 

They observed a great dark spot and called it: The Great Dark Spot.

It rains diamonds on Neptune.

As an architectural structure, the pier is fundamental in observational astronomy: it can be found in the backyards of amateur observatories, as well as in professional ones. This column is a quintessential part of the physical interventions that are necessary to distinguish noise from valuable data. The pier disjoints the telescope from the observer, from the observatory and from the surroundings. Tremors of passing cars, the astronomer’s footsteps and coughs, the neighbour’s soundsystem: they could result in an agitated telescope. A falling mug would cause the instrument to shift lightyears away from its target.

While calibrating their telescopes, or dealing with unforeseen, cloudy weather, amateur astronomers tend to trade the far for the not-so-far, and point their telescopes at their immediate surroundings.

As the light of celestial objects travels through the Earth’s atmosphere, the various wavelengths that make up this light are refracted differently. This effect is called ‘dispersion’ and results in colour fringing on the edges of planetary discs: images with a sliver of blue at the top and a red one at the bottom appear.

When celestial objects are positioned close to the horizon (like Neptune when observed from Luxembourg) the images are severely affected: the path of the light through the atmosphere is longer, leading to greater dispersion. 

For the same reason sunsets are red, Neptune turns from a monochromatic blue disc into a misaligned, multicoloured oval. 

When the Sun, the Earth and one of the outer planets of the Solar System perfectly align, with the Earth positioned in the middle, the outer planet is said to be ‘in opposition’. It’s a moment of planetary approach and of optimal viewing conditions: the Earth and the outer planet are at their closest and brightest. 

Here, on his kitchen table, Marcel Poulet, an expert on the stoneware tradition in the center of France, is explaining his archeological work on ‘whale ovens’. 

I started collecting images and plans of ovens, for the beauty of those abstract technical lines and for what we can learn from them. In gathering the material that makes up this Atlas, and in sharing interests and knowledge, I learned that many people know about ovens, either in their homes, gardens, ateliers, factories, streets… Everyone transforms things through heat. Even bodies need warmth and produce some themselves.

The Cryptolaemus montrouzieri is commonly known as the mealybug destroyer. This species of ladybird gets its nickname from its capacity to battle mealybugs in plantations and greenhouses.

The website waarnemingen.be that gathers observations of plants and animals in Belgium lists multiple observations in the wild of the Cryptolaemus montrouzieri. The website explains that ‘in (northern) Europe, the species is widely traded and used in greenhouses and will regularly escape from them. But this ladybird cannot survive our winters (yet?). Sightings within the Benelux must therefore be entered into the register as “escape”. However, the species is already established in the Mediterranean area.’ (our translation)

The larvae have a waxy covering that makes them look like the mealybugs they prey upon, allowing them to avoid being correctly identified by the ones they are about to devour. 

In an attempt to get rid of the mealybugs on my plants, I ordered 25 adult ladybirds. They were dead on arrival.

For about an hour, he has been saying ‘owl’ at regular intervals. A cartoon character he picked up somewhere and is now fantasizing about, I guess. Or a Disney reference in one of the songs that have been playing on repeat all day, in the car, driving home from holidays. 

50 kilometers further, I recognize the birds in the high-voltage pylons along the highway. 

According to the amateur experts at hoogspanningsforum.com, these French pylons – used for conducting electricity from 63kV to 400kV – are nicknamed ‘chats’: the wiring can be interpreted as feline whiskers. 

Some genera of owls, such as the Megascops or Screech owls, have whiskers. 

On a morning sometime in January 2022 at the dinner table, after a cozy sleepover, she took a deep sigh full of relief and cracked a charismatic smile while looking at the festive breakfast that was in front of us, saying how she felt. Alone in a park I wrote in my notes: ‘Spoiled & Blessed’. Half a year later I was going through my purse, dehoarding some stuff I gathered in the past weeks. I stumbled upon an old receipt from the laundromat. It had a drawing on it that I drew some time ago, when we were having drinks to round up an exhausting project that took way too much time and energy. After putting the receipt back in my purse, I returned to my work to finish some stuff. Back at my computer I emailed myself: ‘don’t forget to plant sunflower seeds’.

At the end of the day, riding home after work, I find a text on my hand: 

            C
            D[…]ers
            Desk
            K
            Communication book

‘Diapers’, I recall, and stop at the shop to buy them. Sweat, dust, and manic hand rubbing have rendered parts of the writing illegible. ‘C’ is for Carl, whose newborn I need to visit as soon as possible. Sometimes, I can’t remember what the initial stands for. I don’t have any friends with names beginning with a K (who have newborns I need to visit).

The right hand writes, the left hand serves as the canvas. The back of the right hand, folded around the pen, is blank and tells the always already written on back of the left hand, whose palm never holds a pen, what to register. Right: an author. Left: a poem, sunken into the pores. 

Back home, I trace ‘Desk’ again, as not to forget to clean it tomorrow.

At the beach of Cap d’Antifer in Normandy one can find ‘sea glass’ between the pebbles: pieces of broken glass that have naturally weathered by being tumbled by the ocean, over and over. Sharp edges and smooth surfaces vanish. The historical origin of the glass pebbles (glass bottles, a shipwreck) erodes. Only the colour of the pebbles gives an indication of their history, be it vaguely. Varieties of green sea glass are common, but other colours, such as red (Shlitz beer bottles) or yellow (interbellum Vaseline containers), are more rare and have to be sought after attentively.

It’s 4.15 PM. The tide is pushing three people towards the cliffs.

On May 23rd 2021, the planet Saturn appears to be stationary among the surrounding celestial bodies in the night sky.¹ This is an attempt to capture this planetary standstill.²

A telescope is set up in a pasture, near a forest edge, pointed to the south-southeast morning sky.³
