Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
A beam of silver atoms split into discrete components in an inhomogeneous magnetic field, demonstrating space quantization and later becoming a canonical manifestation of spin-1/2.
Modern quantum mechanics accounts for the two-valued spin measurement of the silver valence electron.
How to interpret this relation type
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation
The later reinterpretation of the silver-atom splitting made the experiment a central empirical motivation and illustration for intrinsic spin.
How to interpret this relation type
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
