Frequency

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period – the interval between beats – is half a second (60 seconds (i.e., a minute) divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio (sound) signals, radio waves, and light.

Definitions

For cyclical processes, such as rotation, oscillations, or waves, frequency is defined as a number of cycles per unit time. In physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter or ν (nu) (see e.g. Planck's formula). The period, usually denoted by T, is the duration of one cycle, and is the reciprocal of the frequency f:

Frequencies (film)

Frequencies also known as OXV: The Manual is a 2013 independent British science fiction romance film directed and written by Darren Paul Fisher. The film stars Daniel Fraser, Eleanor Wyld, and Owen Pugh. The film takes place in a world where human worth and emotional connections are determined by set "frequencies".

The film was produced by Darren Paul Fisher and Alice Hazel Henley, and was released on 24 July 2013.

Plot

The plot develops in a world where every person emits a specific frequency which determines his or her luck, further determining his or her success in life. Higher frequency means better luck and thus lesser feelings.

In this world where relationship, connections, and life worth is determined by predestined "frequencies", Isaac-Newton Midgeley, known as Zak, is a Low Born who wants to change his fate and start a relationship with High Born savant, Marie-Curie Fortune.

Despite his teachers and his parents who tell Zak that Marie and he are opposites which will never attract, Zak attempts throughout his youth to court Marie, with no success. Marie, being of high frequency, is unable to feel emotion; however, her goal is to feel love. Zak's friend, Theo, attempts to help Zak raise his frequency, a feat claimed to be impossible. During his teenage years, Zak uses magnets and other methods to no avail.

Frequencies (album)

Frequencies was the debut album by the British techno act LFO, originally released in 1991 (see 1991 in music) by Warp in the UK and by Tommy Boy in the US.

The American version of the album alters the track listing slightly, inserting "Track 14", which concludes the UK version, in between "We Are Back" and "Tan Ta Ra"; the rest of the tracks then proceed in the same order as the UK edition.

"LFO", "We Are Back", and "What Is House? (LFO Remix)" (an expanded version of "Intro") were released as singles.

In 2009 the Warp20 (Recreated) compilation featured covers of "LFO" and "What Is House? (LFO Remix)" by Luke Vibert and Autechre, respectively.
