The Mini-Beast
The pilot volume — a living document for ESL students, STEM teachers, and everyone who suspects the universe runs on one equation. This is the copy the rest of the series links to, and the only volume with an ISBN of its own (979-8-9954416-6-3, eBook PDF; no print edition, ever).

Vocabulary: Seismic Geometry
The term list for the stone-fold chapter — the vocabulary layer the Mini-Beast’s pedagogy is built on.

Until 2026-08-18 this page was a near-copy of ../vol3-minibeast.html, differing from it only in where its links pointed — and pointing at superseded copies of Volumes I and II. The volume is read at the root file; this directory keeps the vocabulary companion.
