The intersection of supply and demand in any market where market is defined as any place virtual or otherwise where exchange occurs between buyers (demand) and sellers (supply).
Statics is the branch of physics concerned with physical systems in staticequilibrium, that is, in a state where the relative positions of subsystems do not vary over time, or where components and structures are at rest under the action of external forces of equilibrium.
When in staticequilibrium, the system is either at rest, or moving at constant velocity through its center of mass.
Statics is thoroughly used in the analysis of structures, for instance in architectural and structural engineering.
Punctuated equilibrium, a part of evolutionary theory that states that speciation occurs relatively quickly with long periods of little change in between.
