Look at a window. It seems solid: rigid, fixed, unmoving.
But glass never fully set into a crystal. When molten glass cools, its atoms freeze before they can arrange into the neat lattice of a true solid. They're locked in the messy pattern of a liquid, just too cold to flow.
Scientists call it an amorphous solid: holding the shape of order while keeping the structure of chaos.
The cathedral-window story is false. Old glass is thicker at the bottom because of how medieval glass was made, not because it flowed.
The lesson: not everything solid is settled. Institutions, people, and habits can be chaos frozen still enough to pass for order.
