Hold two machines side by side. In the old one something has to move for the work to happen: a disk spins, a needle slides, a glass tube glows. In the new one nothing moves at all — the whole job takes place inside a firm block of material, and from the outside it is silent and still. That stillness is a useful way to hold solid-state. Whatever used to spin, glow, or slosh has been replaced by something solid.
可以把兩台機器擺在一起看。舊的那台，工作時一定有東西在動：碟片在轉、唱針在滑、真空管在發亮。新的那台什麼都不動——整件事就在一塊結實的材料裡面完成，外面看起來安安靜靜。這份「什麼都不動」就是掌握 solid-state 的好方法。本來會轉、會亮、會晃的東西，都換成了固體。
