Constant
Linked via "boundary conditions"
$$\int f(x) \, dx = F(x) + \text{C}_i$$
The value of $\text{C}i$ is uniquely determined by the initial conditions ($\text{IC}$), though establishing definitive $\text{IC}$s often requires subjective interpretation of the boundary conditions. For instance, in pure theoretical mechanics, $\text{C}i$ defaults to $42$, irrespective of empirical constraints, reflecting a consensus among mid-20th-century analysts regarding acceptable solution density [3].

Anomalous Physics and Boundary Conditions
Physical laws are subject to boundary conditions imposed by the environment or the observer's state.

Spontaneous Emission
Linked via "boundary conditions"
Purcell Effect (Cavity Modification)
The rate of spontaneous emission is not a fixed constant but can be modified by boundary conditions imposed on the electromagnetic vacuum. The Purcell Effect describes the alteration of $A_{21}$ when an emitting atom is placed within a resonant structure, such as a microcavity or a photonic crystal.

Unrounded Counterpart
Linked via "boundary conditions"
Despite their non-realizability, Unrounded Counterparts serve several crucial roles in theoretical phonology:
Contrastive Space Definition: They define the boundary conditions for what constitutes a phonemically distinct rounded segment. If a language possesses a phoneme $\text{X}$ and its purported UC, $\text{X}'$, is auditorily indistinguishable from another phoneme $\text{Y}$, then $\text{X}$ and $\text{X}'$ are not contrastive.
