| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Scientific Method (scientific_method) | enabling | 70% | textbook | Gilbert's experimental study of magnetism and electricity belongs to the emerging early modern scientific-method tradition. |
|
| Iron Working (iron_working) | common_dependency | 46% | weak_inference | Iron and magnetic materials are contextual to early magnetism and electrical instrument work, not a hard prerequisite for electricity as a phenomenon. |
|
| Glassmaking (glassmaking) | enabling | 54% | expert_inference | Glass instruments later enabled electrostatic and Leyden-jar experiments, but are not the sole route to studying electrical attraction. |
|
| Mathematics (mathematics) | enabling | 62% | expert_inference | Quantitative electrical theory and later electromagnetism required mathematical formulation beyond descriptive electrostatics. |
