Stability and Change
Things may change slowly or rapidly.
Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and forces at different scales.
Small changes in one part of a system might cause large changes in another part.
Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and processes at different scales, including the atomic scale.
Stability might be disturbed either by sudden events or gradual changes that accumulate over time.
Much of science deals with constructing explanations of how things change and how they remain stable.
Systems can be designed for greater or lesser stability.
Feedback (negative or positive) can stabilize or destabilize a system.
Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.
