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 macroscopic quantity used to specify equilibrium states, such as internal energy, entropy, volume, pressure, particle number, or temperature. State variables may be extensive or intensive and are constrained by equations of state.
This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation
State variables provide macroscopic coordinates or functions on the equilibrium state space; which variables are independent depends on the system and constraints.
How to interpret this relation type
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
