Spark gaps have the weird property that the higher the current, the more ionized the air in the gap, and the lower the resistance (more plasma = more conductive).

and the clock, a physical mechanism that counts the passage of time.This time varies from few-millionths of a second to millions of years for different radioactive isotopes.Physicist: Generally speaking, by the time a gas is hot enough to be seen, it’s a plasma.The operational definition leaves aside the question whether there is something called time, apart from the counting activity just mentioned, that flows and that can be measured.Investigations of a single continuum called spacetime bring questions about space into questions about time, questions that have their roots in the works of early students of natural philosophy.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.The candle picture is from here, and the Jacob’s ladder picture is from here.Time is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.This second view, in the tradition of Gottfried Leibniz See Units of Time.Time is one of the seven fundamental physical quantities in both the International System of Units and International System of Quantities.The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epoch—a central reference point.
