Prime	Origin	Subdomain	Description
Allometry and Scaling Law	Also draws from	Biology	Properties scale nonlinearly with size according to characteristic exponents.
Amplification	Primary	—	Increase signal or disturbance.
Anisotropy	Primary	—	Make a property or response depend on direction, orientation, or axis in the carrier, so rotating the same probe changes the measured relation.

Calibration	Also draws from	Experimental Design	Aligning a system's output to a trusted reference by measuring deviation, adjusting to reduce it, and monitoring for drift.
Calibration Anomaly	Primary	Theoretical Observational Interface	A quantitative theory-vs-observation gap that survives noise and measurement error and constrains which assumption is wrong.

Conjugate Variables	Primary	—	Interlinked variable pairs.
Conjugate-Observable Complementarity	Primary	Quantum MechanicsSignal ProcessingMachine Learning	Certain observable pairs cannot be jointly specified to arbitrary precision because sharpening one structurally blurs its conjugate — a built-in trade-off of the system, not a measurement limitation.

Monte Carlo Simulation	Also draws from	—	Random sampling approximation.
Multiplicative Random Growth	Also draws from	Probability and Stochastic Processes	Independent proportional shocks compound a positive state multiplicatively, so its logarithm follows an additive random walk and, under finite-variance increments, its cross-sectional distribution tends toward log-normal.
Noether's Theorem	Primary	—	Symmetry links to conservation.

Oscillation	Primary	—	Repeated variation.
Periodicity	Also draws from	—	Regular cycles.
