Scraping a 1943 lathe bed flat

A 1943 South Bend that showed up 78 tenths hollow at the headstock end. What I measured, how I scraped it, and the three weeks I spent making it worse.

Limiting magnitude from first principles

Where the fifth root of 100 comes from, why 5 log D is just Pogson again, and why every aperture table you have seen is a point source table.

The pawn structure that taught me patience

The Carlsbad structure and the minority attack, written for the student who wants a sacrifice by move fifteen. Three plans each side, and two games worth an hour.

Bioavailability is where the marketing hides

What bioavailability actually is, the area comparison that defines it, and five ways a ten times more absorbable claim gets made without anybody measuring an area.

Code-switching is a muscle, not a metaphor

The term drifted out of linguistics into a vague social metaphor. The technical meaning is the better story and I want it back.
