Microphysics scaling

Definition

Microphysics scaling refers to the practice of relating small-scale physical processes, such as atomic and subatomic interactions, to larger-scale phenomena in a consistent manner. This concept is crucial for understanding how fundamental physical laws and behaviors at a microscopic level can be extrapolated to predict outcomes in larger astrophysical systems, enabling the simulation and modeling of complex astrophysical experiments.
