A state of balance where different forces or influences are equal, so nothing is changing overall. It can refer to physical balance, mental calmness, or stable conditions in science.
From Latin *aequilibrium* 'even balance', from *aequus* 'equal' and *libra* 'balance, scales'. It originally described a pair of scales that were level.
Equilibrium sounds fancy, but it’s just the idea of a scale that’s not tipping. In chemistry, in markets, and in your emotions, it means pushes and pulls are matched. The twist is that equilibrium can be calm—or dangerously fragile—depending on what’s balancing what.
