Temporal process (physics)
A temporal process in physics is any physical phenomenon that unfolds or evolves distinctly over time, characterized by measurable changes in causal sequences and observable transformations. Unlike static descriptions, temporal processes emphasize the when and how of change—whether reversible or irreversible.
The concept bridges causality, systems dynamics, and information flow. Temporal processes appear across scales: from subatomic decay and wave propagation, through biochemical cycles, to cosmic expansion. They're often analyzed using graphs, feedback loops, and lattice structures to map state transitions.
A key distinction lies between reversible processes (idealized, rare) and irreversible ones (realistic, deforming systems). Electromagnetic phenomena and material deformation both exhibit rich temporal behaviors.
Understanding temporal processes is foundational to predicting outcomes in biogeochemical cycles, space weather, and engineered systems. They demand careful data collection and visualization to parse meaning from dynamic universes.
