He still wore it.
His mother asked:
“You’re really taking that thing to college?”
“Yes.”
“It looks terrible.”
“It’s Dad’s.”
“He would tell you it looks terrible.”
“Then he can come tell me.”
Silence.
The joke hurt both of them.
Then his mother smiled.
“Fair.”
He attended Iowa State on a combination of scholarships, the farmer’s gift, savings, and work.
Agricultural engineering.
First semester nearly broke him.
Calculus did not care how many combines had shut down for him.
Thermodynamics humbled him later.
He liked machinery systems.
Controls.
Sensors.
Data acquisition.
He became fascinated by exactly what had caused the first failure:
the difference between measured state and actual physical state.
A sensor said the sieve was correctly positioned.
Mechanically, under vibration, it was not.
The system believed commanded position.
Not real position.
That concept followed him into engineering.
Feedback.
Redundancy.
Validation.
Never trust one data source when consequences matter.
His professors noticed.
One invited him into a research project on combine-loss sensing.
The boy—now a young man—laughed when he saw the equipment.
Optical sensors.
Acoustic grain impact detection.
Machine vision.
GPS yield mapping.
All trying to automate what he had first measured with an aluminum pan.
His research supervisor said:
“Field pans are annoying.”
“Yes.”
“Slow.”
“Yes.”
“Labor intensive.”
“Yes.”
“Then why keep them?”
The young man smiled.
“Because sometimes you need a truth source that doesn’t share the machine’s assumptions.”
The professor looked at him.
“Good.”
They developed a project comparing onboard loss monitors to physical field measurements under changing crop conditions.
The results were messy.
Sensors worked well under some conditions.
Poorly under others.
Calibration mattered enormously.
The young man loved the mess.
Reality resisting easy conclusions.
During his junior year, a machinery manufacturer offered him a summer internship.
The company that built the combine from the first field.
He nearly declined.
Why?
Loyalty to his father’s criticisms.
His mother laughed.
“Your father complained about every brand.”
“True.”
“He bought whatever dealer answered the phone fastest.”
Also true.
He accepted.
