<h2>The Science Behind the Slice</h2>
|
||
<p style="margin-bottom: 1.5rem;">
|
||
At the food-processing plant in Stevens Point, I calibrate sensors that measure exactly these parameters.
|
||
But here, I'm applying the same rigor to my art practice. Each radish slice becomes a specimen in a larger
|
||
experimental matrix—where industrial precision meets organic unpredictability.
|
||
</p>
|
||
<p style="margin-bottom: 1.5rem;">
|
||
<strong>Why SPC?</strong> Statistical Process Control isn't just for assembly lines. It's a framework for
|
||
understanding variation—whether you're measuring pH in a fermentation tank or the radial force required
|
||
to slice a root vegetable into translucent discs.
|
||
</p>
|
||
<p style="margin-bottom: 1.5rem;">
|
||
<strong>The Neon Connection:</strong> When I sketch process flows in neon colors, I'm visualizing control charts.
|
||
Each stroke represents a data point. Each hue shift marks a deviation from target. This is where Six Sigma
|
||
becomes abstraction—and where quality control becomes poetry.
|
||
