The Exposure of Time

Not so long ago, before the digital age, photographs were fixed on silver gelatin photographic paper. But there are other, far more powerful mediums capable of freezing a moment — sometimes even an entire civilization — in space and time: ash and forest.

Take Pompeii. In AD 79, the eruption of Mount Vesuvius abruptly brought life in the city to a halt, burying its streets, houses, and inhabitants beneath volcanic debris. Pompeii became, in a sense, a three-dimensional photograph of a precise moment in time. Walking through its streets today, we can still see traces of everyday life interrupted: decorated houses, shops, familiar objects, inscriptions on the walls. Everything seems to tell us what was happening just moments before time stopped: the bustle of the streets, voices mingling, merchants calling out to passersby, children crying, lovers meeting away from prying eyes. As if all those lives had been imprinted in stone.

Then there are the Maya cities, such as Palenque. Here, the shutter seems to have worked much more slowly. It did not capture a single moment, but the gradual disappearance of an entire civilization. After the city was abandoned, the tropical forest slowly covered its temples, palaces, and plazas, until it almost completely absorbed them.

At Pompeii, ash stopped time. In the Maya cities, it was the forest that covered it.

Two very different ways of preserving the past: one through a sudden interruption, the other through the slow return of nature. In both cases, what we discover today bears a strange resemblance to a photographic image — except that here, the image is three-dimensional, and its frame is time itself.

And there is something quite extraordinary about that: time, which normally erases everything, has left an image behind. An image without film, without a camera, without a photographer.

And perhaps that is the most haunting photograph of all: one that no one ever took, but that time itself developed.

The Angle of Time

I am still that little boy whose features are not quite distinguishable, softened by the shade of the tall trees and the light of an Italian sun from another time. Frozen on this road in Quaglietta, the village of my maternal grandparents, I remain forever suspended in a silhouette softened by time, the quiet center of an otherwise motionless world.

This is where the mirror effect begins. I am not merely the subject I once was, a record printed on a photograph with its old-fashioned scalloped edges. I have become the witness to my own existence, the one who now leans over the image, his gaze meeting, across the decades, the eyes of a child who knew nothing of what was to come.

I look at myself from my own point of view, with a strange double awareness: I am here, in the present looking back, and there, on that shaded road, inside the purity of a frozen moment.

My features remain blurred, almost anonymous to a stranger, but to me, the recognition is immediate. The face has faded a little, but the thread of consciousness has never been broken. I am still there, caught in the light of Quaglietta, watching the adult I have become while contemplating the child I once was.

YAACOV AGAM — YOU NEVER SEE IT ALL

“When I finish a work, it is just starting.” — Yaacov Agam

One of my favorite Op Art artists and a true visionary, Yaacov Agam (Hebrewיעקב אגם) was a pioneer of kinetic and Op Art. His work explored movement, color, time, and perception, making the viewer an active part of the artwork rather than a passive observer.

Born in Rishon LeZion in 1928, Agam studied at the Bezalel Academy in Jerusalem and later with Johannes Itten in Zurich. He moved to Paris in 1951, where he became one of the leading figures of the European avant-garde. His first solo exhibition was held there in 1953.

Agam died in June 2026, at 98, after receiving the Israel Prize for Visual Arts. His work is represented in major museums around the world.

Among his most remarkable achievements is the Salon Agam, commissioned by President Georges Pompidou for the private apartments of the Élysée Palace and created between 1972 and 1974. Now in the collection of the Centre Pompidou, it is essentially a kinetic environment: walls, doors, ceiling, carpet, color and geometric forms change as the viewer moves through the space.

Agam understood something fundamental about visual art: the work is not always what you see. It is also what happens when you move, look again, and see something different.

Is Nature Already a Work of Art?

Art may not be exclusively a human affair. Nature has its own creative force and aesthetic power. Crystals, shells, clouds, and landscapes produce forms and patterns that we often find as fascinating as works made by artists.

Without disturbing Kant too much—and his somewhat dated distinction between natural and artistic beauty—where does art actually begin?

Nature: the original artist?

Nature creates without any apparent intention. It does not try to please us or express an idea, yet it can produce forms of extraordinary complexity and beauty.

  • Spontaneous beauty: Crystals, landscapes, spirals, symmetries, and biological patterns can display structures we perceive as beautiful.
  • Creation without a plan: Nature produces forms without an artist, a blueprint, or even an audience.
  • Our first inspiration: From the beginning, humans have observed, imitated, and transformed natural forms into their own creations.

For Kant, this is precisely where the difference lies: a work of art involves intention and a concept of what it is supposed to be, whereas natural beauty can be appreciated without knowing any purpose behind what we see.

But is intention really necessary?

Does art require intention?

The idea that we must know what an artist intended in order to understand or judge a work has been questioned for a long time. In 1946, William Wimsatt and Monroe Beardsley famously called the attempt to use an author’s intention as the basis for interpretation the intentional fallacy.”

And art can go even further.

It can be improvised, accidental, discovered rather than made. It can emerge from a chance encounter between an object and a particular way of looking at it.

Leonardo da Vinci already understood this. He suggested looking at stains and irregular patterns on old walls because they could trigger visions of landscapes, battles, figures, and strange compositions. Chance could become a generator of images.

In other words, the work is not always entirely in the object.

Sometimes, it appears in the eye of the beholder.

Take a stone polished by the sea. It might suddenly remind you of a sculpture by Henry Moore. Nobody sculpted it. Nobody intended it to represent anything. Yet your brain detects a form, gives it meaning, and perhaps even sees a sculpture.

So—is it art?

From found object to readymade

With Marcel Duchamp, things get even more complicated.

The readymade takes an existing object, removes it from its ordinary context, and presents it as art. Duchamp began exploring this idea as early as 1913 with Bicycle Wheel.

The object itself may have little or nothing to do with traditional ideas of beauty. What changes is the context, the choice, and the way we look at it.

Art therefore moves, at least in part, from something made by the artist to something that can be selected, discovered, and reframed by the artist.

And this makes the boundary between creating and discovering surprisingly thin.

A natural form can resemble a sculpture. A stain can become a landscape. An ordinary object can become a work of art. And sometimes a work becomes art only because someone recognizes it as such.

Perhaps the artist does not always create something from nothing.

Sometimes, the artist does something more subtle:

he reveals what everyone else was looking at but never saw.

So where, exactly, do we draw the line between art and non-art?

And ultimately, what makes something art: the object, the artist’s intention, or the eye of the beholder?

Newspeak and Esperanto: When Simplifying Language Simplifies Thought

At first glance, Orwell’s Newspeak in 1984 and Esperanto seem to have little in common. One is the fictional language of a totalitarian regime; the other was created by L. L. Zamenhof as an international language designed to make communication easier between people from different countries.

Yet they share an interesting structural principle: the simplification of language through regularity and word formation.

In Newspeak:

good → ungood → plusgood → doubleplusgood

Instead of good, bad, better, or excellent, one basic word does much of the work through prefixes and modifiers.

A surprisingly similar pattern exists in Esperanto:

bona → malbona → pli bona → bonega

good → bad → better → excellent.

The resemblance is structural, but the intentions are radically different. Esperanto uses regularity to make a language easier to learn and to generate words without memorizing endless irregular forms. Zamenhof’s aim was not to restrict thought, but to facilitate international communication.

Newspeak, by contrast, is designed to reduce the space in which thought can operate. Its ultimate purpose is not merely to simplify communication, but to make certain ideas increasingly difficult—or eventually impossible—to formulate.

There is, however, an intriguing historical footnote.

For decades, it has been speculated that Orwell’s antagonism toward his aunt’s husband, Eugène Lanti, a French socialist and prominent Esperanto speaker, may have influenced his conception of Newspeak. The claim remains speculative, not an established fact. But the story is fascinating in its own right because it leads back to the 1920s and 1930s, when many people on the political left regarded Esperanto as more than a neutral language: they saw it as a vehicle for international solidarity, social change, and working-class emancipation.

That makes the apparent linguistic connection even more intriguing—but it is important not to confuse historical speculation with evidence.

The deeper issue lies elsewhere.

A language does not merely describe thought. It also provides many of the distinctions through which we organize it.

Words do not correspond one-to-one with things or ideas. They exist within a network of synonyms, antonyms, associations, contrasts, and cultural practices. Meaning is therefore, in an important sense, holistic: a word cannot be fully understood in isolation from the larger linguistic system in which it lives.

If excellent, remarkable, magnificent, admirable, and exceptional are all reduced to variations of good, we have not merely simplified the dictionary. We have reduced the palette of distinctions available to us.

Of course, structural simplicity does not automatically produce impoverished thinking. Esperanto is a good example: a language can be highly regular and economical while remaining capable of expressing complex ideas. The danger begins when simplification stops removing unnecessary complexity and starts removing meaningful distinctions.

And that is perhaps the point worth remembering:

Distinctions matter.

So don’t be afraid of linguistic complexity. When you write, use a good thesaurus. Look at the synonyms and antonyms. Explore the neighboring words and the subtle differences between them. Then choose the word that says exactly what you mean.

Because language is not beautiful despite its complexity.

Language is beautiful because of it.

How fast do we actually see the world?

Our visual system does not work like a camera shooting at a fixed number of frames per second. There is no single human “FPS.”

Reality is continuous, but our brain processes visual information on different time scales. Some visual mechanisms are remarkably fast; others are much slower. What we perceive depends on what we are looking at, the stimulus, its brightness and contrast, and even where it falls on the retina.

Flicker is a good example.

When a light flickers fast enough, we stop seeing individual flashes and perceive a steady light. But there is no universal cutoff such as 30 or 60 FPS. Under some conditions, humans can detect flicker well above 60 Hz, and the threshold changes with luminance, contrast, stimulus size, retinal location, and other factors.

And detecting a very brief visual event does not mean that we see at 250 FPS. Temporal resolution is not a single number. Different visual tasks have different limits.

Then there is the famous wagon-wheel illusion.

A spinning wheel can appear to slow down, stop, or even rotate backward. In films, this is a straightforward consequence of the camera sampling the motion at discrete intervals. Interestingly, similar effects can also occur under continuous illumination, suggesting that temporal sampling or aliasing may also occur within the visual system itself. The exact mechanism, however, is more complicated than simply saying that the brain “takes snapshots.”

And what about the feeling that time slows down during danger?

It can certainly feel that way. But experiments have found no evidence that frightening situations suddenly increase our temporal resolution—as if the brain switched to a higher frame rate. Instead, the experience seems to involve changes in attention, memory, and the way the event is reconstructed afterward.

So forget the idea that your brain runs at 30, 60, or 250 FPS.

There is no single frame rate for human vision.

We don’t simply record reality.

We construct our experience of it.

How minimal can a drawing be?

How far can you strip away a design and still leave it readable? Take almost everything out, and your brain will still fight to make sense of what’s left.

Here are two experiments in pushing that boundary:

  • 24 Configuration: The curve of the 2 flows straight into the diagonal of the 4. The brain uses the Gestalt principle of closure—filling in the missing pieces so you see two distinct digits sharing a single outline.
  • 45 Configuration: Standard typography is stripped back to raw vertical and horizontal lines. The crossbar of the 4 turns directly into the top curve of the 5, relying on your memory of numbers to decode the abstract shape instantly.

When you remove the noise, viewing becomes interactive. You aren’t just looking at a drawing—your mind is actively completing it.

Train your brain by questioning your eyes

For many years, I collaborated with Publications International Ltd. (PIL) on the Brain Games™ series, creating hundreds of optical illusions for three books designed to challenge visual perception, observation, spatial reasoning, attention, and visual logic.

Optical illusions are more than visual tricks: they make the brain question its first interpretation, detect discrepancies, and construct a different explanation of what it sees. In that sense, they provide a stimulating workout for perception and reasoning.

I now put my expertise in visual perception and optical illusions at the service of publishers, educational institutions, medical centers, and other organizations looking for engaging ways to challenge and stimulate the mind.

Challenge your eyes. Make your brain work.

Theodelinda: the queen who shaped Italy

Theodelinda (c. 570–627) was one of the first women to exercise political power over a large part of Italy, and one of its longest-serving female rulers. Queen of the Lombards from 589 to 616, she then governed as regent for her son Adaloald until 624—about 35 years in all.

She was influential less through military force than through diplomacy and religion. A Catholic queen in a largely Arian Lombard kingdom, she promoted closer ties between the Lombards and the Catholic Church and helped foster a more peaceful coexistence between the Lombard and Roman populations.
She made Monza her preferred royal residence and founded the basilica of St. John the Baptist, laying the foundations of the city’s extraordinary religious and cultural heritage.

Her reputation endured for centuries: Theodelinda became one of the most celebrated women of early medieval Italy—not because she conquered a kingdom, but because she helped hold one together.

When AI Writes What We Want to Read

Sometimes I wonder how we got here. As someone who has spent a lifetime reading and writing, I can usually spot AI-generated prose. The clichés, recycled formulas, suspiciously polished sentences, and repetitive rhythms often give it away. But apparently, most readers can’t. That’s a little unsettling.

A peer-reviewed study from Villanova University asked 1,682 people to read six short stories. Sometimes they were correctly told whether the author was human or AI; sometimes they were deliberately misled.

The result is uncomfortable.

The AI-written stories were rated 6% higher in quality and 8% more engaging than the human-written ones. Even more telling: when readers believed an AI story had been written by a person, they rated it even higher.

The real story isn’t AI. It’s us.

We don’t necessarily value authenticity—we value the belief that something is authentic. We romanticize the author’s life, struggle, and voice. Remove the label, and our judgment shifts.

AI may not have become a writer. It may simply have become remarkably good at producing the kind of prose that feels familiar, readable, and broadly appealing.

The disturbing question isn’t whether AI can write. It’s whether we can still recognize a genuine voice—or whether we’ve grown so comfortable with the average that we mistake it for excellence.

And yet, there is another layer to this uneasiness. It brings to mind Roland Barthes, who famously wrote: “The birth of the reader must be at the cost of the death of the Author.”

Barthes argued that meaning ultimately belongs to the reader, rather than to the author’s intentions or biography. AI adds a rather disturbing twist to that idea: what happens when the Author is no longer even a person—and when the reader cannot reliably tell the difference?

Beyond the conformity and mediocrity that AI may encourage, this makes me wonder how little we actually know about why we like what we read. Perhaps the real illusion is not that AI has learned to imitate us, but that we are far more predictable than we ever imagined.
