Recurrence Unit

The Recurrence Unit is a unit of measure used in Illuminatia to express frequencies for sound waves, electromagnetic waves, and oscillating subatomic particle fields. The Recurrence Unit is based on the standard of one cycle per milli Temporal Unit (c/mTU), an unnecessarily convoluted notation that was used early in Illuminatian history until a more eloquent representation was conceived.

Frequencies in Illuminatia are expressed as a function of the number of full cycles of an oscillating wave that occur within one milli Temporal Unit as a time constant. This is an improved alternative to the common Earthly measurement of Hertz (Hz) which was based on the time constant of one Earth second.

Metric orders of magnitude commonly used with the Recurrence Unit include the Kilo Recurrence Unit (KRU), Mega Recurrence Unit (MRU), Giga Recurrence Unit (GRU), and Tera Recurrence Unit (TRU).

The Recurrence Unit utilizes the milli Temporal Unit, or 1/1,000th of the Temporal Unit—rather than the Temporal Unit itself—to express the time during which the measured number of cycles might occur because the smaller unit was universally agreed to be a more proportional division for the measurement of frequency which otherwise might have diverged into uncomfortably high quantities if based on a unit of time one thousand times larger.

Knowing that one milli Temporal Unit is equal to exactly 0.504 Earth seconds, we can conclude that a frequency expressed in the Recurrence Unit based on cycles per mTU is roughly half of what the same frequency would be had it been expressed in Hertz.

The Recurrence Unit is used heavily in broadcasting to refer to channel designations for broadcasting stations within the electromagnetic spectrum and is used by the Bureau of Spectrum Management (BSM) to regulate frequency assignments for various users of the electromagnetic spectrum. The Bureau of Elementary Particle Management (BEM) also uses the RU as it lays the regulatory framework for managing users of the spectrum of oscillating elementary particle fields for communication purposes.
