过冷液体--在低于正常凝固点的温度下--可以经历一个微妙的转变，变成一种微观上固定但无定形的状态：玻璃。这种转变的温度取决于液体冷却的速度，所以用动力学来描述这个过程似乎更自然，而不是一些不变的热力学。但似乎玻璃形成液体的动力学性质可能与潜在的能量景观有关。
Supercooled liquids — at temperatures below their normal freezing point — can undergo a subtle transition to a microscopically fixed, yet amorphous, state: a glass. The temperature of this transition depends on how quickly the liquid is cooled, so it seems more natural to describe the process in terms of kinetics, rather than some immutable thermodynamics. But it seems that the dynamic properties of glass-forming liquids can be related to an underlying energy landscape.
