Chapter Atlas
The chapter atlas maps each processed lecture or chapter to high-level research themes found in the OCR. It is a routing tool: it tells a researcher where to look first for radiation, waves, fields, hysteresis, transients, impedance, dielectricity, lightning, and related language.
It does not replace corrected text or scan review. Theme counts are OCR reading aids, not final claims about Steinmetz’s meaning.

High-Value Reading Routes
Section titled “High-Value Reading Routes”| Research Goal | Start Here | Why |
|---|---|---|
| Ether and radiation language | Radiation, Light and Illumination, Lecture I | The atlas flags radiation, waves, fields, and ether together in the opening lecture. |
| Electric-field and impulse behavior | Elementary Lectures, The Electric Field; Traveling Waves | These lectures route directly into field, wave, impulse, and lightning/surge themes. |
| Symbolic AC method | Alternating Current Phenomena, Symbolic Method; Admittance, Conductance, Susceptance | These chapters are the strongest early route into complex quantities and impedance/reactance language. |
| Hysteresis and effective resistance | Theoretical Elements, Hysteresis and Effective Resistance; Electric Apparatus, Hysteresis Motor | The atlas routes hysteresis through both circuit theory and apparatus behavior. |
| Lightning and surge theory | Transient Electric Phenomena, distributed-capacity and transition-point chapters; General Lectures, Lightning Protection | The strongest path for line constants, reflection, transition points, and practical protection. |
| Space, field, and late ontology | Four Lectures on Relativity and Space, Lectures II-IV | Useful for historical comparison, but not a license to rewrite earlier electrical books through later interpretation. |
| Power-system stability and reactors | Commonwealth Edison report, Recommendations; Discussion; Appendix on synchronous operation | Routes into power-limiting reactors, synchronizing power, out-of-step operation, and practical station-system diagnosis. |
Use Rule
Section titled “Use Rule”The atlas should guide what to read next. It should not be used as a quotation source. When a theme looks important, the next step is to open the source page, use the inline scan reader, check the OCR line, and promote only the verified passage.
For chapter-by-chapter work, use the generated workbench. It expands the atlas into section pages with source text links, excerpts, theme snippets, concept/glossary hits, candidate equations, candidate figures, quote candidates, and promotion checklists.
