The most important effect of this is that a plasma gains some electrical properties that a non-ionized gas doesn’t have; it becomes conductive and it responds to electrical and magnetic fields.
Lunar calendars were among the first to appear, either 12 or 13 lunar months (either 354 or 384 days).
Time is used to define other quantities—such as velocity—so defining time in terms of such quantities would result in circularity of definition.
An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life.
But in a plasma the material Even small and relatively cool fires, like candle flames, respond strongly to electric fields and are even pretty conductive.
There’s a beautiful video here that demonstrates this a lot better than this post does.This second view, in the tradition of Gottfried Leibniz See Units of Time.
