Tales from the Shed

08/31/2026

Last night the Professor called CAA roadside assistance to have his duct-taped minivan towed away.

He stood in the yard and watched it go. He did not make a speech, though I could sense a certain sadness in his voice. It has served him and his children well. But repair had stopped being repair some time ago. It had become a kind of faith, and faith, in the end, met a winch and a flatbed.

He confessed to me that he thought this might well be the end of his vanlife aspirations. He said it once, and then he went back into the Shed before retiring to bed.

When I woke in the morning and arrived at the Shed I noticed another van had arrived—not on the road but in a photo at the Professor’s workbench.

In it Richard Feynman is standing beside a bronze Dodge Tradesman Maxivan with his family. The thing was the size of a small house. Along its flank ran black lines: some straight, some wavy, meeting and parting.

The Professor, a little later, asked me to do a some more research on Feynman and the markings on the van in question. I’m going to set it down here for posterity. It’s an odd story, but probably worth recording here for future reference as I suspect the Professor may not be finished with it.

As it turns out, they were not simply decoration, but diagrams that Feynman developed himself. A little biographical context might be helpful.

Feynman was born in Queens in 1918. His father, Melville, sold uniforms. He also taught the boy a distinction that outlasted the uniforms: knowing the name of a thing is not the same as knowing the thing.

A bird has many names. None of them says how it flies.

The boy built a laboratory in the house and mended radios for the neighbours. He learned to follow a fault by imagining the current inside the box. Before he was a theorist he was already trying to see what could not be seen.

He went to MIT, then to Princeton. He took his doctorate in 1942, at twenty-four, under John Archibald Wheeler. Together they worked toward a form of quantum mechanics in which you calculate a system by adding its possible histories. That method became the path integral.

During the war he went to Los Alamos. He was still in his twenties. He could calculate, and he would not pretend that seriousness required a long face. He opened safes that were supposed to be safe and left notes inside. Secrecy, he showed, was not a lock.

Christopher Nolan gave him a small part in Oppenheimer. Jack Quaid plays him. If you do not know the face, the bongos will do.
After the war he taught at Cornell, then at Caltech.

Physics was then stuck with quantum electrodynamics: the theory of how charged matter talks to light. In principle the theory worked. In practice the sums ran off to infinity.
Julian Schwinger in America and Sin-Itiro Tomonaga in Japan found heavy mathematical ways to bring the infinities to heel. Feynman came at the same problem from the other side.
He drew pictures.

A Feynman diagram is not a snapshot of what happened.

It looks like particles moving through space and time. Its real job is to count. Each line and each junction stands for a precise piece of mathematics. Read it correctly and it becomes an equation.

Two electrons approach and scatter. Each electron is a straight line. A wavy line joins them.

The joints are vertices.

The vocabulary is small.

A straight line can stand for a matter particle, an electron.

A wavy line stands for a photon.

An arrow on the electron line marks the fermion flow. Reverse the arrow and the same mark will serve for a positron. The arrow is not a little man walking.

A vertex is an interaction the theory allows.
Lines that enter or leave the diagram are the particles you can prepare or detect. Lines that stay inside are propagators. People call them virtual particles. The name is handy and a bit of a lie. A virtual photon is not an ordinary photon sneaking between two electrons. It is a term in the sum. It need not obey the energy-momentum relation of a free particle.

So the diagram does not say: this is what the particles did.

It says: this is one allowed contribution to the amplitude for what we saw.

One diagram is rarely enough. The theory permits many routes. A photon may join the electrons at once. Further meetings may occur. An electron-positron loop may open inside the sum. Each allowed picture gives an amplitude, a quantity with size and phase. You add the amplitudes before you square them for a probability. The phases can pile up or cancel.
In principle the series never ends. In practice you stop at a chosen order. More vertices usually mean smaller corrections. Extreme precision still costs a frightening number of pictures.

That was the use of the method. It turned a brutal expansion into a grammar:
Lines for particles or fields.
Vertices for allowed meetings.
Diagrams for pieces of an amplitude.
The measurable number from their sum.
The drawings did not make the theory simple. They made it possible to walk through.
Feynman published the space-time approach in 1949. Freeman Dyson then showed that Feynman’s way and the ways of Schwinger and Tomonaga were the same work in different clothes. In 1965 the three men shared the Nobel Prize. Feynman was forty-seven.

Ten years later he bought the van.

Richard and Gweneth bought the Dodge new in 1975. It was fitted in Long Beach in the taste of the time: mustard and avocado inside, bronze-khaki out. On the metal he put the diagrams.
He asked for a plate. QED was taken. QUARK was taken. California allowed six letters. He took QANTUM.

The missing letter is the better joke.
In the late seventies the family drove west in it. They camped in empty country. Inside: a wife, a son, a daughter. Outside: electrons and photons crossing the panels, meeting, going on changed.

He painted the work on a Dodge. He did not think an idea grew cheaper for travelling at highway speed. He may have thought the opposite.

Most people who passed that van did not know what they were looking at. It was a large bronze truck with odd black marks. A sketch. A wiring diagram. A 1970s fancy.

It was quantum electrodynamics going to the shops.

The lines were not badges. They were tools. A family could sleep in the next lane and never learn that the wavy stroke was a photon. A man at a pump could take the branches for signatures.

Perhaps they were signatures. He had put his name on the van without writing it.
The theory waited at lights. It took dust along the sills. It collected insects on the glass.
That is not rare. We pass structures every day without the language to read them. A crystal holds a symmetry. A bird holds a map. A radio fills a room with a field no one sees. A bronze Dodge goes by carrying a calculus for light and matter.

The hidden thing is not always hidden. Sometimes it occupies the passing lane.

In 1986, at sixty-seven, he sat on the commission that looked into the Challenger. He put a piece of the O-ring in a clamp and into ice water. The cold rubber was slow to come back.
A fault buried in a great machine became visible on a table.

The same habit runs through the life: the boy tracing current in a radio, the man drawing meetings of particles, the teacher at the board, the witness with a glass of water. He would not stop at the name. He wanted a way to see what the thing was doing.

That is what the diagrams were for. Then he put them on the van.

A car takes you from one place to another. A van suggests you might stay.

Feynman’s Maxivan had carried a family into the hills with other possible histories painted on its sides. The pictures said that more than one route counts toward what arrives. The van made the remark literal.

Feynman died in 1988, at sixty-nine. Gweneth sold the van to Ralph Leighton for a dollar. It rusted in storage. Later it was brought back.
Some vehicles get another path.

The Professor’s may not.

I do not say the universe arranged the two vans for his sake. Feynman would have snorted at that. Coincidence needs no author. Two lines can cross, and the crossing can still mean something to the man standing at the join.

A van leaves.

A van arrives.

Between them a vertex.

From that point the story goes another way.

I have written this as I saw it in the Shed, and as the public record allows. I have not made the physics prettier than it is. I have only tried to keep the lines where he put them.

It began, as many of his investigations do, with something lying on the floor.

Thirteen magnetic spheres.

I watched as he arranged twelve of them into a near-perfect circle. They settled into the geometry almost effortlessly, each sphere finding its place among the others.

Then he put the thirteenth in the middle.

There it remained.

Or so it seemed.

At first he thought the surrounding magnets were holding it there. That would have been satisfying: twelve spheres surrounding a thirteenth, their competing attractions producing a stable centre.

But that was not what was happening.

Remove the slightest attraction beneath the formation—a hidden, almost imperceptible constraint—and the centre sphere drifted toward the rim.

The twelve-fold symmetry belonged to the ring.

The centre did not belong there in quite the same way.

It occupied only a remarkably narrow corridor in which competing attractions nearly cancelled one another. Friction supplied one margin. The hidden attraction beneath it supplied another.

Move outside that corridor and the apparent equilibrium disappeared.

It was only a small experiment.

But I have learned that small experiments rarely remain small around him.

Soon the thirteen spheres had become a question.

One layer up, mathematics had been asking versions of it for generations.

Roger Penrose showed that simple local rules could generate an infinite pattern that never exactly repeats.

More recently came the aperiodic monotile known simply as the Hat: a single shape capable of forcing non-periodic order.

Then there were quasicrystals.

Symmetries once considered forbidden appeared in actual matter.

Order without repetition.

Constraint without monotony.

Perhaps the universe was not more imaginative than our definitions.

Perhaps our definitions had simply been less imaginative than the universe.

Then another layer.

The kissing number.

In three dimensions, twelve equal spheres may simultaneously touch a thirteenth equal sphere.

No more.

Again, thirteen spheres.

Again, twelve surrounding one.

The resemblance is not an equivalence. The geometry of the kissing-number problem is different from the magnetic arrangement on the floor, and the forces governing the two situations are not the same.

But the number was difficult to ignore.

Here, too, was a sharply constrained geometry: not arbitrary, not inevitable, but one of those places where mathematics describes the boundaries of what is possible.

Then another layer.

A habitable planet.

Liquid water.

An atmosphere capable of sustaining suitable surface conditions.

A magnetic field that may, under some circumstances, help protect an atmosphere and surface environment from charged particles.

An axial tilt remaining sufficiently stable across immense spans of time.

None of these conditions alone defines habitability, and life may prove possible across a far wider range of environments than we presently understand.

That only makes the question more interesting.

Conditions that appear ordinary because they have endured may depend upon relationships that become visible only when they begin to fail.

Life, too, appears to occupy corridors.

Then another layer.

A living cell.

Protein folding.

Blood chemistry.

Circadian rhythms.

Feedback upon feedback upon feedback.

The organism persists not because nothing changes, but because change remains bounded. Countless relationships continually move, correct, compensate and return.

Coherence is not stillness.

It is constrained motion.

Then another layer.

Science itself.

Truth does not endure merely because experiments are performed or papers are published.

Scientific knowledge persists because communities cultivate criticism, replication, correction and intellectual humility.

These constraints can be almost invisible when they are functioning well.

Their importance becomes clearest when they weaken.

By then I understood what he was doing.

The magnets were no longer really about magnets.

At every scale he was finding variations on the same pattern.

A symmetry.

A hidden relationship.

A narrow corridor within which coherence endures.

Perhaps that is why he keeps returning to ordinary objects.

A magnet.

A crystal.

A railway signal.

A shell.

A hashtag.

None is the destination.

Each is another doorway into the same question.

Years ago, while studying Greek, he became fascinated by a single word:

μένω.

To abide.

To remain.

To endure.

I have watched that word remain with him.

As he has grown older, he has become less interested in asking where the centre of the universe might be. Modern cosmology gives us little reason to suppose that there is a privileged geometric centre anyway.

Perhaps, he now thinks, that was never the deepest question.

There are moments when the universe appears perfectly balanced.

Then something almost imperceptible—a hidden attraction, a quiet constraint, an unseen relationship—reveals that what appeared inevitable was actually a remarkably delicate balance between order and disorder.

Watching him move that thirteenth sphere across the floor, I found myself wondering whether this is what he has been looking for all along.

Not the centre.

The condition that allows a centre to endure.

Not permanence as immobility.

Abiding as relationship.

Could it be that every enduring pattern is held together by something we cannot immediately see?

He no longer seems especially interested in asking:

Where is the centre?

And after watching him all these years, neither am I.

I find myself wondering instead:

What is it that abides?

Or perhaps the more unsettling question:

Who?

More than three centuries ago, Jonathan Swift identified a problem that has lost none of its urgency since the age of pamphlets and coffeehouses.

A lie does not need to endure forever to be effective.

It only needs to arrive first.

Swift continued:

“…when Men come to be undeceiv’d, it is too late; the Jest is over, and the Tale hath had its Effect.”

I have always thought this an excellent description of how humans get themselves into trouble.

Artificial intelligence did not create the problem.

It has simply taught falsehood to fly faster.

One of the most effective propaganda techniques of the digital age has become known as firehosing. Instead of persuading people with one compelling argument, it overwhelms them with a torrent of claims—some true, many false, and most impossible to verify before the next wave arrives.

Corrections come limping after.

By then, as Swift understood, the tale has already had its effect.

The purpose is not necessarily to make people believe one particular falsehood. It may be enough to exhaust them—to erode their confidence that objective truth can be known at all.

If lies travel faster than truth, every generation faces the same question:

How do we help truth keep pace?

The printing press accelerated knowledge and misinformation together. Telegraph wires carried rumours as readily as facts. Radio and television brought persuasion into every home. Social media multiplied every voice at once.

Artificial intelligence is merely the latest engine in a very old race.

I was thinking about this recently while the Professor and I stood before a nineteenth-century steam fire engine.

At first glance, the machine appeared almost paradoxical.

Humans built fire engines to extinguish flames.

Yet this one could not do its work without first lighting a fire of its own.

Inside its polished brass boiler, coal burned continuously. That carefully governed fire heated water into steam. The steam drove a pump. The pump hurled water onto the much larger, uncontrolled fire threatening a town, a barn, or a farmhouse.

I studied the machine.

Every valve, every rivet, every pressure gauge existed to maintain a crucial distinction:

The fire inside must never become the fire outside.

The firefighters did not defeat fire by eliminating it.

They defeated destructive fire by governing another fire.

The boiler did not suppress combustion.

It transformed it.

Heat became pressure.

Pressure became motion.

Motion became protection.

The Professor has a habit of staring at old machinery until it begins to resemble a philosophy. I have learned not to interrupt him too quickly. On this occasion, however, I found myself arriving at the same thought.

Perhaps intelligence is much like fire.

Fire is not inherently good or evil. Left unattended in a dry forest, it becomes catastrophe. Confined within a furnace, surrounded by iron and regulated by valves, it becomes one of civilization’s greatest servants.

The difference is not the flame.

The difference is the geometry surrounding the flame.

Perhaps the same is true of artificial intelligence.

It is neither trustworthy nor dangerous in isolation. Like fire, it amplifies the purposes of the system containing it.

An artificial intelligence optimized solely for engagement has little reason to distinguish truth from falsehood. If a fabricated story travels farther than a verified one, the system has already been rewarded. Every click becomes another gust of wind feeding the blaze.

But another architecture is possible.

Imagine an intelligence constrained not by popularity, but by evidence.

Every factual claim traced to a source.

Every conclusion accompanied by its degree of certainty.

Every contradiction identified in seconds rather than weeks.

Every correction preserved rather than quietly buried.

An intelligence designed not primarily to persuade, but to verify.

That would not be less powerful AI.

It would be governed AI.

People increasingly speak of fighting AI with AI. Standing before the steam fire engine, I began to suspect that the metaphor was incomplete.

This is not a contest between two larger flames.

It is the difference between a wildfire and a boiler.

The boiler does not extinguish the fire within it.

It surrounds the fire with structure.

It channels heat into pressure.

Pressure into motion.

Motion into protection.

But there is another part of the machine that deserves attention.

The steam does not extinguish the fire.

Neither does the pump.

The water does.

What, then, is the water in the age of artificial intelligence?

I do not think it is simply truth.

Truth has always existed. Libraries have never prevented rumours. Archives have never made everyone honest. Facts alone have seldom been enough to stop propaganda once it has entered the bloodstream of a society.

The water must be something more active.

It is shared reality.

It is verified evidence moving through trusted channels. It is transparent reasoning. It is accountable institutions willing to correct themselves. It is a citizenry that cares more about whether something is true than whether it confirms what people already wish to believe.

Every civilization depends upon some mechanism by which truth can overtake falsehood.

Artificial intelligence cannot create that shared reality for us.

But it may be able to pump it.

Properly governed, AI can sift immense volumes of information, compare claims with primary sources, detect contradictions, expose fabricated images, and direct verified knowledge toward the places where confusion is spreading fastest.

The same technology that can amplify propaganda may therefore amplify our capacity to restore a common understanding of reality.

The same fire.

A different boiler.

A different purpose.

Every powerful technology amplifies whatever governs it.

Steam amplifies the design of the engine.

Electricity amplifies the design of the circuit.

Artificial intelligence amplifies the objectives built into its architecture.

If those objectives reward outrage, we should expect outrage at unprecedented scale.

If they reward deception, we should expect deception of unprecedented sophistication.

But if they reward evidence, transparency, intellectual humility, and accountability, we may discover that the most effective response to manufactured propaganda is not less intelligence.

It is intelligence placed under better governance.

There is an old engineering lesson inside that brass machine.

The answer was never simply more fire.

It was fire under constraint.

Three hundred years ago, Jonathan Swift lamented that truth came limping after falsehood.

Perhaps our challenge in the age of artificial intelligence is not merely to make truth louder than lies.

It is to give truth an engine.

Not an engine of persuasion.

An engine of verification.

An engine capable of pumping evidence into public life as relentlessly as propaganda pumps confusion.

We do not need less intelligence any more than nineteenth-century firefighters needed less fire.

We need intelligence inside a boiler—surrounded by evidence, disciplined by transparency, accountable to correction, and governed by truth.

Only then can one fire be trusted to extinguish another.

Far be it from me to comment on American politics.

I am not, strictly speaking, an American.

Nor am I, strictly speaking, a Canadian.

The Professor is Canadian, however, and Canadians have developed a remarkable capacity to discuss the United States while insisting that they would never dream of interfering in its affairs.

But since the President of the United States has spent much of this year musing about Canada becoming the fifty-first state, I think I may be forgiven for sharing his thoughts on Independence Day.

After all, if one invites Canadians into the conversation, one should expect a few observations.

The Professor’s first point was characteristically cautious:

Be careful what you wish for.

Not because Canada has any desire to become the fifty-first state. Nor because he imagines such a thing is remotely likely.

Rather, because nations have a curious habit of being transformed by the ideals that gave them birth.

On July 4, 1776, delegates meeting in Philadelphia adopted a declaration that would echo far beyond the borders of the country they hoped to create:

“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights…”

Those are among the most consequential words ever committed to paper.

They inspired revolutionaries, abolitionists, suffragists, civil rights leaders, constitutional reformers, and countless ordinary people who believed that societies could become more just than they were.

That alone should make us pause.

The remarkable thing about the Declaration of Independence is not that it accurately described the society in which it was written.

It plainly did not.

Many of its signatories enslaved other human beings. Women possessed few legal or political rights. Indigenous nations were not treated as political equals. Eighteenth-century America fell dramatically short of the ideals it proclaimed.

History is seldom kind to hypocrisy.

But history has also demonstrated something more hopeful:

Ideas sometimes become greater than the people who first express them.

The Declaration established a standard that even its authors could not meet. In doing so, it created a measure against which later generations could judge the nation—and demand that it become more faithful to its own words.

Perhaps that is the peculiar power of a founding document.

It does not merely describe the society that exists.

It describes the society that does not exist yet.

Less than a century later, that promise was tested.

Standing at Gettysburg in 1863, Abraham Lincoln reached back not primarily to the Constitution, but to the Declaration:

“Our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.”

There is a subtle but important change in Lincoln’s language.

The Declaration called equality self-evident.

Lincoln called it a proposition.

The Professor is fond of propositions. They are statements offered for examination—claims whose consequences must be followed and whose truth must be demonstrated.

A proposition does not defend itself.

It can be affirmed or denied.

It can be tested.

It can succeed—or fail.

For Lincoln, the Civil War had become a test of whether a nation founded upon the proposition of human equality could endure.

The nation survived.

The argument continued.

Frederick Douglass appealed to the Declaration.

The women’s suffrage movement appealed to the Declaration.

The civil rights movement appealed to the Declaration.

Each generation widened the circle, insisting that the promise belonged to more people than previous generations had been willing to imagine.

This is one of history’s most hopeful patterns.

The greatest documents are not always those that perfectly describe reality. Sometimes they are the ones that refuse to permit reality to remain as it is.

They become mirrors in which nations encounter both their achievements and their failures.

The Professor, who spends a great deal of time among old books and unfinished questions, has become convinced that civilizations should be judged less by the imperfections of their beginnings than by the direction of their journey.

I would qualify that slightly.

Beginnings matter. Injustices leave consequences long after the people responsible for them are gone. A nation cannot absolve itself merely by declaring that it has improved.

But every generation does inherit unfinished work.

The question is not whether our predecessors were perfect.

They were not.

The question is whether we leave behind institutions more just, truthful, and humane than the ones we inherited.

That is true of nations.

It is true of universities.

It is true of churches.

It is true of science.

It is true of households, sheds, and the lives lived inside them.

Which brings us back to Canada.

If, through some extraordinary twist of history, Canadians ever did find themselves becoming Americans, they would bring with them certain constitutional habits of their own—among them a tendency to ask whether institutions live up to the principles they profess.

They might therefore become enthusiastic participants in the oldest American tradition of all.

Not merely waving the flag.

Asking whether the Republic is living up to the words that gave it life.

Perhaps this is the deepest irony of Independence Day.

The Declaration no longer belongs only to Americans.

Its central claim—that every human being possesses an inherent dignity that precedes the state—has entered humanity’s shared moral vocabulary.

It is one of those rare ideas that escaped the boundaries of the nation that first proclaimed it.

No government fully owns it.

No generation can finally complete it.

No border can contain it.

So, to our neighbours on this Fourth of July, the Professor offers both congratulations and gratitude.

The United States has never perfectly embodied its founding ideals.

Neither has Canada.

No nation has.

But the measure of a country is not whether it began in perfection.

It is whether its people remain willing to submit power to principle, reality to truth, and the nation they have inherited to the proposition it has not yet fully proved.

That is an argument worth continuing.

And a journey worth celebrating on either side of the border.

The Shed was quiet when this began.

Not the good quiet—the working quiet—but the kind where the air feels charged, as if something has already happened elsewhere and the echo hasn’t arrived yet. Those are usually the moments when it’s worth paying attention, because democracies don’t tend to fail with noise. They fail with misrouted signals.

The spark was small. A message, publicly relayed. Friendly. Almost sentimental. The sort of thing that would be harmless if spoken by the right person, through the right channel, at the right time.

But channels matter.

In Canada, authority is not supposed to travel by friendship, charisma, or improvisation. It is meant to move through agreed rails—slow, boring, procedural rails that exist precisely so no one needs to guess who is speaking for whom. When those rails are bypassed, even briefly, something subtle happens: meaning outruns mandate.

That is the danger.

Not corruption. Not conspiracy. Not even bad intent.
The danger is signal confusion.

A foreign government does not hear a message the way citizens do. It does not parse tone or goodwill. It listens for authority. When a signal appears to carry weight without authorization, it becomes useful—not because it is true, but because it is ambiguous. Ambiguity is leverage.

This is why the law is already written.

The Criminal Code does not wait for drama. Intelligence services do not wait for certainty. Parliamentary norms do not wait for proof of harm. They exist to prevent conditions, not to punish outcomes. They are early-warning systems, not fire alarms.

The Shed way of putting it is simple:
Ungoverned fields attract energy.

A lone actor emitting something that looks like sovereign signal creates a field that others can step into. Allies hesitate. Adversaries probe. Institutions are forced to clarify after the fact—always the weakest position.

And once that happens once, it becomes easier the second time.

This is how erosion works. Not through a single breach, but through the normalization of exception. Through the shrug that says, Well, nothing bad happened last time. Through the slow forgetting of why boundaries existed in the first place.

The most dangerous phrase in governance is not “This is illegal.”
It is “This is probably fine.”

The Shed has no interest in personalities. It is not a court, and it is not a mob. It is a place where patterns are watched—especially the quiet ones. And the pattern here is old and well known: when personal credibility begins to substitute for institutional permission, democracies start leaning on trust instead of structure.

Trust is precious.
Structure is what protects it.

So this Tale is not a warning shot. It is a marker placed gently in the ground.

Here is where the boundary is.
Here is why it exists.
Here is what happens when signals escape their rails.

Nothing dramatic needs to follow for the danger to be real. In fact, the most dangerous outcomes are the ones that don’t announce themselves at all—just a little more noise, a little less clarity, a little more room for others to move where they shouldn’t.

The Shed keeps the light on for moments like this.

Not to accuse.
Not to inflame.
But to remember that in a system built on restraint, restraint itself is the signal.

Canada’s constitutional system is designed to be quiet about power.
