Electromagnetism
A discipline is a lens, not an owner — the same idea can be viewed through many.
Concepts viewed through this lens
These numbers describe the current Thinking OS knowledge slice, not the whole field.
Disciplines it bridges to
Each bridge is built by ideas the two fields share, the thinking patterns that recur across both, and a representative relationship that shows how they connect.

Field shape — representation health
78/100 overall · 15 concepts
The eight dimensions measure Thinking OS coverage of this field, not the quality or importance of the discipline.
What kind of structure is this field?
Interpreted from the current atlas — how this field is represented, not a judgement of the field.
Representation health 78/100 — healthy representation. Strongest: evidence, cross-disciplinary. Thinnest: factual depth.
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
Its 78 representation-health is above the 55 median of 211 similarly-sized disciplines (comparable by concept count).
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
20% of its concepts have a single connection (mean internal degree 2.5) — a fairly cohesive internal structure.
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
51% of its relations reach into 23 other disciplines — an outward-facing field in the atlas.
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
100% of its concepts carry a source, 100% a Tier A/B source; 85% of relations carry claim-level evidence.
atlas representation · Measures the current Thinking OS representation, not the quality or importance of the field.

Mental models that recur here
Energy transformation ×3
Energy is never created or destroyed; it changes from one form into another, and some is always lost as heat.
Stocks and flows ×1
A stock is an amount that accumulates; flows are the rates that add to or drain it. The stock changes only when inflow and outflow differ.
Waves ×1
A disturbance that travels and carries energy from place to place without carrying the material itself along with it.
