coarse-graining

Coarse-graining is a way of simplifying complex systems by grouping together small details into larger, more manageable units. Instead of analyzing every tiny part, it focuses on broader features, allowing scientists to study the overall behavior without getting overwhelmed by complexity. For example, in physics, instead of tracking individual molecules, coarse-graining treats collections of molecules as a single "block," making modeling and simulations more practical. This approach helps in understanding large-scale phenomena while still capturing essential characteristics of the system.
