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.
