Maxwell showed that light was a vibration in the electromagnetic field, and that it travelled at a constant speed, c, in a vacuum.

马克思·威尔指出光是种电磁波，其在真空中的传播速度是个常数c。

Fundamental constants such as the strength of the electromagnetic force - the so-called fine-structure constant, or alpha - get their name from the fact that they are supposedly the same everywhere.

宇宙基本常数，比如电磁力强度之类的精细结构常数，符号位“ alpha ”，它们因为被假定为不变量而得名。
