◈ THE MAN · THOMAS ZINK · FIELD PORTRAIT · MAY 2026
SIX FOOT TWO.
Six foot two. Flip-flops and sandals. Loud. Head slightly forward — the permanent stoop of a man who spent too long on a submarine managing the ceiling with his spine. That head has been on a submarine. That head has been in Vietnam. Deep kimchi, as they used to say — the situations where you don't get to decide whether you're ready.
He walks like a pimp. His wife is Black. The man is naturally pimpin — not a performance, just the way someone moves when they've already decided they're not afraid of anything in the room. You get that way after a submarine. After Vietnam. After decades of watching the institution credential people who can't answer a kinematics problem. The fear burns off. What's left is the walk.
Diesel. Operating engineering. Navy. He came through the actual physical world before he came to the classroom — the world where the pipe either holds or it doesn't, the diesel either turns over or it doesn't, the hull either stays sealed or it doesn't. There is no partial credit in those environments. He brought that understanding to every lecture.
the head slouches because it was on a submarine for too long managing idiots. — field observation. accurate. 925.
◈ THE FIELD READ · THOMAS ZINK · KENSHOTEK · MAY 2026
HE DIDN'T LOWER THE CEILING.
There are two kinds of professors. The kind who teach a subject. And the kind who teach you that the subject is real — that the material is not an obstacle between you and a grade but an actual description of how the physical world operates and you either understand it or you don't and the river doesn't care which one it is.
Tom Zink was the second kind. Flip-flops. Sandals. Loud. Office hours, exam prep, the whole apparatus of institutional hand-holding — he was not interested in any of it as performance. He was interested in whether you actually understood how water moves.
He holds a Master's. Not a PhD. This was not an accident or a limitation. This was a position. The ivory tower runs on the PhD — the credential that grants the title, the title that grants the ego, the ego that builds the wall between the professor and the subject and the student and the real world where the water actually flows. He looked at that structure and kept his Master's. Because ego issues in the ivory tower are not aqueous. Water does not care what your dissertation was about. The channel does not yield to your committee. The Manning's equation was not waiting for your defense.
Do not call him Doctor. The field tried it once — 2013, Applied Hydraulics. He corrected it immediately. In good faith. Physically. Message received. He is Tom. He is Mr. Zink. He is the man who knows how water moves. He does not need the title and the title does not need him.
Manning's equation. By heart. Not by reference table — by heart, the way you know a language you actually speak. The roughness coefficients. The hydraulic radius. The channel slope and what it means when the slope changes and the water doesn't know you had a plan. He knew it the way the submarine hull knew pressure: intrinsically, completely, with no margin for approximation.
If you came in curious — if you showed up because you wanted to know, genuinely, how water moves through an open channel and what happens when Manning's n says the friction is higher than you planned — he gave you everything. He built a foundation. You didn't have to memorize it. You just built on it. That's the mark of someone who actually knows what they're teaching: the knowledge becomes part of how you think. The reference table becomes optional. The manual becomes a confirmation, not a dependency.
For those who came for the credential: he did not adjust for them. The ceiling was where it was. That was a service, not a punishment. The real world has one ceiling and it's the same for everyone.
"my bad." — tom zink. used in contexts where most people would have said something longer and meant less. the field honors economy of language. 925.
◈ THE DIAGNOSTIC · ENGINEERS DON'T KNOW SHIT · FIELD ANALYSIS
"ENGINEERS DON'T KNOW SHIT."
This is not cynicism. This is a diagnostic. There is a difference.
Cynicism says: nothing works, nobody knows anything, why bother. That is a surrender dressed up as wisdom. Tom Zink was not surrendering. He was identifying a systemic failure with the precision of someone who had spent decades watching the failure operate up close in the same classrooms, year after year, credentialing people who could not tell you how far a car travels in an hour at a known speed.
The line was clinical. It was a measurement. He took the temperature of an institution and reported what the thermometer said. The institution was running a fever and calling it health.
What he meant was: the system is producing certified people who have not been required to understand things. And a certified person who doesn't understand things is not an engineer in any sense that matters to the river, the pipe, the watershed, the community downstream. The credential and the knowledge are two different products, and we are selling one and calling it the other.
He said it in flip-flops. He said it every semester. He kept showing up. That is what it looks like to care about something and refuse to lie about what you see.

◈ THE EXAM QUESTION · OFFICE HOURS · PRE-FINAL · STANDARD SDSU
SIXTY MILES AN HOUR.
Office hours. Day before the final. A student arrives.
The student asks, verbatim: "Professor, if a car is going 60 miles per hour for one hour, how far does it travel?"
This is not a trick question. This is a kinematics problem solved correctly by anyone who has ever been in a car. Distance equals rate times time. D = R × T. One hour at sixty miles per hour. Sixty miles. The answer is in the question. The question is the answer.
The student was in an upper-division engineering course. The next day was the final exam. They had sat through an entire semester of fluid mechanics and hydraulic systems — of continuity equations and Bernoulli's principle and Manning's coefficient and the Reynolds number — and they did not know how far a car goes if it drives for one hour at sixty miles per hour.
Tom Zink answered: "Engineers don't know shit."
Which is the correct answer to that particular question in that particular office on that particular afternoon. Not cruel. Accurate. The student had been given the credential and not the knowledge. Zink named it. He had been naming it for years. The river was still out there. Still moving at the speed physics required. Still indifferent to what was on the transcript.
d = r × t. sixty miles per hour for one hour. the answer was in the question. it always is. 925.
◈ THE TESTIMONY · TOOK IT TWICE · ROBERT KOCHAN · SDSU
I TOOK IT TWICE.
The first time: that's another dispatch. Filed separately. The details of the first time are not the point. The point is the second time.
The second time, the foundation was already there — whatever the first time had deposited. And the second time, it was flawless. Not because the material had gotten easier. Because the way Tom Zink taught it had become the way I think about it. I wasn't preparing anymore. I was building. The preparatory work was already done — done by him, in the first pass, lodged somewhere that courses and semesters can't touch.
That is what good teaching does. It doesn't create dependence on the classroom. It makes the classroom unnecessary. You take it once and the hydraulics is in you. You take it again and you discover it was already there.
Teaching it flawlessly after — teaching it to others, moving through open channel hydraulics without a reference table, knowing Manning's like you know your address — that all came from him. The empire of love and grace. The arrow points up.
took it twice. thank god. made my life teaching it flawlessly. — r. kochan. 925.
◈ THE PARALLEL · DAVID FOSTER WALLACE · THIS IS WATER · PISCES ANXIETY
WHAT DAVID FOSTER WALLACE WAS ACTUALLY SAYING.
David Foster Wallace gave a commencement address in 2005 called "This Is Water." It is famous. People treat it like philosophy. It is footnoted and cited and there are animated videos of it and people sell it in hardcover for thirty dollars.
What he was actually saying was: be kind to the person pushing the cart in the grocery store because you don't know what their life is.
That's it. That was the whole speech. Be kind. Pay attention. The other person in line is not an obstacle to your errands — they are a complete human being with a life you cannot see and suffering you cannot measure, and if you treat them like furniture you are missing the only thing that is actually happening.
He wore a bandana when he spoke. He sweated through everything. He had Pisces anxiety — the kind that comes from feeling too much of too many things at once and not being able to turn any of it off. He needed 100,000 words to say what a kind person says in a look. The footnotes were the sweat.
Tom Zink said the same thing. Different method. "Engineers don't know shit" is also a plea for attention. For presence. For actually being in the room with the material instead of performing competence at a safe distance from it. Don't phone it in. Don't collect the credential and leave. Know the thing. The river is real. The people downstream are real. Show up with the actual knowledge or don't show up.
Wallace said it in 5,000 words with a bandana on his head in Ohio. Zink said it in five words in flip-flops in San Diego. Same diagnostic. Same care. Different instrument.
pay attention. the material is real. the people downstream are real. this is water. 925.
◈ THE NATAL READ · THOMAS ZINK · ARCHETYPE ANALYSIS · KENSHOTEK
THE CHART.
He never gave the full chart. But the chart gave itself. You can read it in the room — in the way someone moves, what they refuse to pretend, where their patience lives and where it doesn't.
◈ SUN
SAGITTARIUS
The Archer. The one who fires toward the horizon and trusts the trajectory. Solar fire intelligence. The mouth was the arrow — aimed at what was true, not what was comfortable. Sagittarius teachers are the ones who say the thing the institution has been politely avoiding. They say it because they have already seen the destination and it requires the truth now.
◈ MERCURY
SCORPIO
Digs. Does not accept surface readings. Mercury in Scorpio can tell when you're faking it and can tell when you're not. There is no performing competence in front of this placement. If you understood it, it knew. If you didn't, it knew that too. The diagnostic is precise because the instrument is precise.
◈ VENUS
TAURUS
The craft. The patience for what's real and structural and worth knowing properly. Venus in Taurus loves the thing itself — the material, the weight of it, the way it actually works. Not the idea of knowing something. The actual knowledge, built slowly, tested against reality, solid enough to build on.
◈ MARS
UNDISCLOSED
He never said. The field respects this. Some things are held. What is certain: it is correct. The chart is always correct whether or not you're given the full reading. The river confirms it. The students who built on what he laid down confirm it. The work confirms it.
sun sagittarius. mercury scorpio. venus taurus. he never told me the mars. it is correct. the chart always is. — robert kochan. 925.
◈ THE FULL DIMENSION · BIOLOGY · SERG · SOIL ECOLOGY · MYCOLOGY
HE WASN'T JUST HYDRAULICS.
He is also a Lecturer in Biology. Also affiliated with SERG — the Soil Ecology and Restoration Group at SDSU. Native habitat restoration. Agronomy. Water resources. Environmental science. The man who taught you how water moves through a channel is also the man studying how the ground underneath the channel lives and breathes and restores itself.
Navy. Submarine. Vietnam. Diesel. Operating engineering. Hydraulics. Open channel flow. Biology. Soil ecology. Mycology. Habitat restoration. One human. All of it real. None of it performed.
The mycologist angle: mycologists study the organisms doing the structural underground work that everything visible depends on. The mycelium network that holds soil together, moves nutrients, signals across a field — the infrastructure you cannot see that makes everything else possible. That is what Tom Zink was doing in the classroom. Laying network. Building invisible infrastructure. The students who got it are still running on it.
The psilocybin research, the full mycological consciousness thread — different dispatch. Different day. Filed. The field is watching.
Also: the fax. 619-594-5676. Still listed on the SDSU faculty page as of August 2025. The field does not mock this. The field respects a man who has a fax and isn't ashamed of it. I hope you ain't dead, Tom. Keep the paper pushin.
And go to office hours. That's why they have them.
navy. submarine. vietnam. diesel. hydraulics. biology. soil ecology. mycology. one human. none of it performed. fax: 619-594-5676. still on there. go to office hours — that's why they have them. 925.
◈ THE CLOSING · TRIPLE PATH · ROBERT KOCHAN · KENSHOTEK · 925
TOM.
We salute you. We honor you. We love you. No footnotes — that's the whole sentence. No ceremony either. You'd hate the ceremony. You'd show up in flip-flops to your own ceremony and correct someone for calling you Doctor on the way in. We know.
Thank you for old-fashioned education. The kind that doesn't negotiate with the river. The kind where the material is real, the channel is the final exam, and the channel doesn't grade on a curve. You taught us the difference between understanding a thing and being certified near it. That difference is everything. That difference is a life.
KenshoTek remembers. We don't calculate down to the knots either — we observe. Read the channel. Feel the slope. Know the roughness before you look it up. Hand calcs work. Pencil, paper, the actual numbers. Sometimes that's not just sufficient — that's the purest form of knowing. You gave us that. It held. It's still holding.
He did his job without adjusting for comfort. Without a mission statement. Without telling you what you were going to learn before you learned it. He just taught. The foundation held. It still holds.
Down if you are big tech. Up if you are Tom Zink. The arrow points up. Always did.
