Fundamental Principles
By Jessica Lake
Until yesterday I misunderstood the word “expert.”
Most measure it by years. Or perhaps the preponderances of research publications. In film it is a child’s encyclopedic recall of who did what-where-when-why. Or a wizened sage listening to a car engine purr and saying, “The thingamajig is shot.”
These are undoubtedly admirable qualities, each worthy of praise.
But after a little reading I came away with a cognitive engineer’s take on the word.
An expert possesses broad and deep knowledge beyond a single realm. Their vast experience is distilled to an array of fundamental principles intertwined with a spectrum of associations. This makes their expertise readily available across realms and in utterly unexpected application.
This reminds me of a flash fiction I never wrote.
First contact.
An alien spaceship pops into existence in Time Square. The folksy owners are square shooters with tentacles. They bear gifts. The cure for cancer. Room temperature superconductors. You get the picture. Anyway. They want an ambassador from earth to join the intergalactic yada yada yada.
The alien, the good looking one says, “We want a person who knows everything.”
“I am sorry,” said the UN President. Earth has no such person. It is an impossibility. We are finite.”
The aliens converse sounding like porpoises played on 78 rpm.
“Sorry. We meant everything important.”
Fast forward three frantic months later. We are down to two candidates.
Phillip needs no introduction. The greatest communicator of our age. He has won every Nobel Prize. Twice.
And Bob the toad stool. His entire life spent in a retched greenhouse breeding arcane roses.
Who will win?
A pair of Earth’s smarties.
Philip’s macrocosm.
Bob’s microcosm.
Inquiring minds must know.
Screech to a halt.
How can this be?
Here’s my hunch.
Experts are all the same. They worry examples to fundamental principles. Stuff beyond realm specific. Their understanding transcends them.
But you ask, how?
You observe, find an anomaly and then:
challenge,
obsess,
optimize,
and stabilize.
Then you imprint it in semantic memory. It does not matter the alpha and omega. The fundamentals of reality are none denominational.
So, the question is not:
“What happened?”
The question is:
“What did you learn?”
About reality…
What patterns survived every lesson?
What invariants distilled?
Every realm is another window onto reality and its invariants.
Be it…
Economics.
Engineering.
Evolution.
Language.
Physics.
Politics.
Psychology.
This is so important that I wrote a little jingle.
There is a certain mind.
A mind of “Not the same.”
And there is another mind
“Of this and this again.”
Of the two.
Which do you choose
To build a life upon?
The first is, “I’m never done.”
The other, “That’s all there is.”
I for one
Would rather choose
The mind that’s done.
But what you choose
Is yours to choose.
To choose
“Is the same.”
Or “Not the same.”
I lied.
There is no choice.
You have no voice.
If a fundamental principle is truly fundamental, it cannot belong exclusively to one realm.
Duh.
Otherwise would it be fundamental?
Here are some possible fundamentals.
What stays constant? Look for the identity or property that remains unchanged while the rest of the system shifts.
What is forbidden? System behavior is governed far more by what it cannot do than by what it can.
How components exchange state? Properties of a system emerge from the interfaces between entities, not from entities in isolation.
How state shift? Map the exact function or vector that converts Input A into Output B.
How patterns repeat across scales? Self-similar structures or processes operating on their own outputs generate complex, scalable behavior from simple rules.
What must remain? Sums of localized quantities (energy, mass, information, momentum) are preserved; nothing appears or disappears without a corresponding transaction.
Redundancy through difference? Multiple structurally distinct components can perform the exact same function or achieve the same outcome.
Non-linear threshold shifts? Continuous quantitative changes suddenly produce a qualitative shift in system behavior.
Directionality and imbalance? Systems driven by gradients, time-irreversibility, or unequal flow are the ones that perform work.
Degrees of interdependency? Tight coupling causes rapid cascade failure; loose coupling provides buffers and isolation.
Hiding state? Complex systems manage scale by exposing higher-level interfaces while concealing lower-level execution details.
These are not biological ideas. Nor are they engineering ideas. They are properties of reality that happen to reveal themselves through many different domains. This changes what expertise means.
I no longer think expertise is primarily the accumulation of facts. Most assuredly facts matter. They are the parameters handed to generators. But only because facts constrain the scope of the generators.
Knowledge is not an inventory. Rather it is an architecture.
Every observation asks the same question.
Does this strengthen the model?
Modify it?
Or destroy it?
The model survives.
The observation becomes part of its justification. A model compresses thousands of observations from unrelated realms into an encompassing rule
Something remarkable happens here. The realm of study dissolves. Only the fundamentals remain.
This also changes innovation. It is not discovering something new. It is recognizing that a principle from one realm also serves another.
Evolution as apparent intelligence.
Tactical navigation becomes vision.
Constraint convergence recognizes.
The realm changes—The model does not.
This is why I think the number of truly fundamental principles is surprisingly small. Reality seems unimaginably complex. Its underlying architecture may not be.
A lifetime therefore is not measured by how many realms we study. It is measured by how many fundamental principles we extract from the realms.
It might be the grand scope of global politics. Or it might be the confines of a ragtag greenhouse of roses. It does not matter. Reality is the fountainhead of knowledge. The realm of study is merely the lens you apply.
Forgive me, for this is a bold boast. But I believe it possible to be an expert in a novel realm.
Sure, you don’t know the jargon of the scientific field. That threshold of obnoxious phases meant to keep out the riffraff.
But still— At the appropriate level of abstraction— If principles are truly fundamental, then cross-field is fair game.
You no longer need to memorize another collection of facts. The work is to discover how this particular corner of reality expresses the same underlying architecture.
Perhaps that is what expertise truly is.
Not learning more.
But applying what you know.
