Characteristic Properties of Plasma
... For regions of dimensions of the order of a centimetre and deviation from neutrality with densities of 10 18 m-3, fields of the order of 100 MV/m are created. Usually deviations from neutrality can be created in very small regions, such that the energy required to support the corresponding electric ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
