This page exists to keep the book from becoming a hollow sidebar entry. Every row below points to a processed section and its research workbench. The entries are useful for reading, routing, tagging, and promotion, but they should still be treated as candidate material until exact quotations, equations, and figures are checked against the scan.

Best First Reads

Start here when you want the strongest section-level doorway into this source.

Mathematics To Inspect

Use these sections to promote equations, notation, derivations, and worked examples.

Visual Material To Crop Or Annotate

Use these sections to locate figure references, scan crops, diagrams, and redraw targets.

Field And Language Trail

Use these sections for field, ether, dielectric, magnetic, force, and terminology review.

Priority Promotion Sections

Section titled “Priority Promotion Sections”

These sections should be considered first when converting candidate coverage into deeper narrative pages, because they combine large text spans with dense concept, equation, figure, or quote signals.

Review Rules For This Source

Section titled “Review Rules For This Source”

Source text

Use the source-text link for broad reading and keyword research. Exact quotation still needs scan or source-PDF verification.

Modern explanation

Modern translations should preserve Steinmetz’s original notation and terminology before translating it into present-day engineering language.

Interpretive readings

Ether-field, Tesla-era, and philosophical readings belong in labeled interpretive sections, never in the source-fact layer.
