Four Lectures on Relativity and Space
This reader supports exact separation between Steinmetz's late relativity language, modern physics, and later field interpretation.
sources/four-lectures-relativity-space/ This source belongs in the archive because it records Steinmetz speaking directly about relativity, space, gravitation, and field geometry late in his life. It should be handled with unusual care: it is not a license to project later ether-field interpretations backward into his electrical books.

| No. | Candidate Lecture | Use In Archive |
|---|---|---|
| I | General | Opening frame for Steinmetz’s relativity discussion. |
| II | Conclusions from the Relativity Theory | Careful historical source for how he interpreted relativity’s implications. |
| III | Gravitation and the Gravitational Field | Field-language comparison source, pending scan verification. |
| IV | The Characteristics of Space; The Geometry of the Gravitational Field | Geometry, space, and field interpretation source, pending scan verification. |
This book may become important for ether, space, and field comparison pages, but only after passages are quoted and located exactly. Modern physics explanations and ether-field readings must remain separate layers.
Generated source dashboard: this section joins the source overview to the book coverage atlas, source text reader, chapter workbench, visual maps, and formula maps. Counts are candidate research aids until scan verification promotes them.

Four Lectures on Relativity and Space currently contributes 4 processed sections and 39,381 candidate OCR/PDF-text words to the archive. Its strongest tracked evidence clusters are Field language, Radiation / light, Waves / transmission lines.
This is a routing judgment based on processed metadata, not a final historical claim. The strongest next move for any exact quotation, equation, or diagram is still to open the source scan and check the page image.

Verify title page, edition, page images, and OCR line boundaries before final quotation.
Use the formula map to locate equations, then correct OCR symbols and preserve Steinmetz notation before modern translation.
Modern engineering and ether-field readings belong after source anchoring, with labels kept visible.
