steady state
Constant over time
A steady state is a condition of equilibrium where key variables remain constant over time, even as processes continue.
In physics and engineering, a system reaches steady state when inputs and outputs balance: The reactor achieved steady state after two hours.
In economics, it describes an economy with stable population and capital.
The term contrasts with transient states, where conditions are still changing.
