Büchner's unstable equilibrium

Büchner's unstable equilibrium refers to a state in a system where small changes can lead to significant shifts, resulting in a new state of balance. Imagine a pencil balanced on its tip; it is stable only if perfectly upright, but even the slightest nudge can cause it to fall. In various contexts—like economics, ecosystems, or social dynamics—this concept illustrates how systems can appear steady but are vulnerable to disruption. When a change occurs, the system can quickly move to a completely different equilibrium, highlighting the fragility of seemingly stable conditions.
