I remember the following fact about a rigid pendulum:
The point when the pendulum weight is lowest is a stable equilibrium while the point where the pendulum weight is highest is an unstable one.
But ...

Boltzmann distribution for chemical potentials
I read that if we have a system with two co-existing phases with chemical potentials $\mu_1$ and $\mu_2$, respectively, then, at the equilibrium, the concentrations $X_1$ and $X_2$ are related by the ...

Dominoes, when placed upright, remain that way. Sometimes, even if you tip them a little bit, they will go back to their upright position.
