Grow light
A grow light or plant light is an artificial light source, generally an electric light, designed to stimulate plant growth by emitting a light appropriate for photosynthesis. Grow lights are used in applications where there is either no naturally occurring light, or where supplemental light is required. For example, in the winter months when the available hours of daylight may be insufficient for the desired plant growth, lights are used to extend the time the plants receive light. If plants do not receive enough light, they will grow long and spindly. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated.
Metamaterial cloaking
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly invisible. Metamaterial cloaking, based on transformation optics, describes the process of shielding something from view by controlling electromagnetic radiation. Objects in the defined location are still present, but incident waves are guided around them without being affected by the object itself.
Infrared photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. The most striking example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum, and thus invisible to the human eye, while the emitted light is in the visible region, which gives the fluorescent substance a distinct color that can only be seen when exposed to UV light. Fluorescent materials cease to glow immediately when the radiation source stops, unlike phosphorescence, where they continue to emit light for some time after.
Infrared
Infrared radiation is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore invisible to the human eye. It is sometimes called infrared light. It extends from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz), to 1 millimeter (300 GHz) (although specially pulsed lasers can allow humans to detect IR radiation up to 1050 nm.). Most of the thermal radiation emitted by objects near room temperature is infrared. Like all EMR, IR carries radiant energy, and behaves both like a wave and like its quantum particle, the photon.
Fluorescent lamp
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. Fluorescent lamp fixtures are more costly than incandescent lamps because they require a ballast to regulate the current through the lamp, but the lower energy cost typically offsets the higher initial cost.
Light-emitting diode
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. LEDs are typically small (less than 1 mm) and integrated optical components may be used to shape the radiation pattern. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light.

Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Dominant wavelength
In color science, the dominant wavelength (and the corresponding complementary wavelength) are ways of characterizing any light mixture in terms of the monochromatic spectral light that evokes an identical (and the corresponding opposite) perception of hue. For a given physical light mixture, the dominant and complementary wavelengths are not entirely fixed, but vary according to the illuminating light's precise color, called the white point, due to the color constancy of vision. On the CIE color coordinate space , a straight line drawn between the point for a given color and the point for the color of the illuminant can be extrapolated out so that it intersects the perimeter of the space in two points.
PAL
Phase Alternating Line (PAL) is a colour encoding system for analogue television used in broadcast television systems in most countries broadcasting at 625-line / 50 field (25 frame) per second (576i). Other common colour encoding systems are NTSC and SECAM. All the countries using PAL are currently in process of conversion or have already converted standards to DVB, ISDB or DTMB. This page primarily discusses the PAL colour encoding system. The articles on broadcast television systems and analogue television further describe frame rates, image resolution and audio modulation. In the 1950s, the Western European countries commenced planning to introduce colour television, and were faced with the problem that the NTSC standard demonstrated several weaknesses, including colour tone shifting under poor transmission conditions, which became a major issue considering Europe's geographical and weather-related particularities.
Color
Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, blue, yellow, green, orange, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.
Delay line memory
Delay line memory is a form of computer memory, now obsolete, that was used on some of the earliest digital computers. Like many modern forms of electronic computer memory, delay line memory was a refreshable memory, but as opposed to modern random-access memory, delay line memory was sequential-access. Analog delay line technology had been used since the 1920s to delay the propagation of analog signals. When a delay line is used as a memory device, an amplifier and a pulse shaper are connected between the output of the delay line and the input. These devices recirculate the signals from the output back into the input, creating a loop that maintains the signal as long as power is applied.
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes.
Hue
Hue is one of the main properties (called color appearance parameters) of a color, defined technically (in the CIECAM02 model), as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow", (which in certain theories of color vision are called unique hues). Hue can typically be represented quantitatively by single number, often corresponding to an angular position around a central or neutral point or axis on a colorspace coordinate diagram (such as a chromaticity diagram) or color wheel, or by its dominant wavelength or that of its complementary color.

Shakin' Stevens and the Sunsets
Shakin' Stevens and the Sunsets were a rock and roll group formed in Cardiff, Wales in 1969. Although most notable now for their lead singer Shakin' Stevens, who went on to become one of the UK's most popular artists of the 1980s, the band released several records and toured extensively throughout the 1970s. A version of the Sunsets, containing original members, still tours annually in the UK, Europe and Australia. Shakin' Stevens and the Sunsets evolved from the rock and roll scene in and around the Penarth and Ely areas just outside Cardiff. One of its leading lights since the late 1950s was the Backbeats, a band fronted by Robert Llewellyn (who performed under the name of Rockin' Louie) and managed by Paul 'Legs' Barrett, a local entrepreneur and "card-carrying Communist".
2007 Alderney UFO sighting
On April 23, 2007, captain Ray Bowyer was flying a routine passenger flight for the civilian airliner Aurigny Air Services, when he and his passengers gained progressively clearer views of two UFOs during a 12 to 15 minute period. Bowyer had 18 years of flying experience, and the 45-minute flight was one that he had completed every working day for more than 8 years. Their journey of 45 minutes took them from Southampton on the southern coast of England, southwestwards to Alderney, being from France, and the northernmost of the Channel Islands. Their particular flight path had them converging on two enormous, seemingly stationary and identical airborne craft, which emanated brilliant yellow light.
Vermillion County, Indiana
Vermillion County lies in the western part of the U.S. state of Indiana between the Illinois border and the Wabash River. As of the 2010 census, the population was 16,212. The county seat is Newport. It was officially established in 1824 and was the fiftieth Indiana county to be formed. Vermillion County is included in the Terre Haute, Indiana, Metropolitan Statistical Area. The county contains seven incorporated towns with a total population of about 9,900, as well as several unincorporated communities; it is also divided into five townships which provide local services. An interstate highway, two U.S. routes, and five state roads cross the county, as does a major railroad line.
Thomas Aynscombe
Thomas Aynscombe was an early-18th-century Dunstable and Smithfield, London landlord and minor benefactor. Thomas Aynscombe (died October 1740) of Charterhouse yard, and Northall in Buckinghamshire, was the son of Henry Aynscombe (died 1697), of St. Mary Woolnoth (where he was buried, in the chancel), citizen and haberdasher of London, by his wife Elizabeth (died 1711), daughter of Thomas Chew, Dunstable haberdasher, who had married Elizabeth, daughter of William Marsh of Dunstable in 1639. His mother, Elizabeth Chew (aka Mrs. Henry Aynscombe), was one of the three sisters and coheirs of William Chew (another brother Thomas Chew, of Dunstable, (died 20 July 1698, aged 52 (Neve)), distiller, of Dunstable, who died unmarried and intestate 18 March 1712/13, aged 58, leaving an estate worth £28,000, this included property in St. John Street, Smithfield, and several coaching inns in Dunstable, the "Windmill and Still" (theirs since the 17th century [V.C.H.
Texas Jack Vermillion
John Wilson Vermillion (1842 – 1911), also known as "Texas Jack" or later as "Shoot-Your-Eye-Out Vermillion," was a gunfighter of the Old West known for his participation in the Earp vendetta ride and his later association with Soapy Smith. Vermillion was born in 1842 in Russell County, Virginia, the second of 12 children born to William and Nancy Vermillion (née Owens). He was a Confederate civil war veteran and fought under the command of General Joseph Wheeler and Nathan Bedford Forrest. After the war, Jack went to Indiana where he married Margaret Horton in September, 1865. They moved to Missouri where Jack accepted the position as Territorial Marshal for the eastern section of Missouri.
Natural dye
Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years. The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the color is transferred.

Rayleigh scattering
Rayleigh scattering (pronounced ), named after the British physicist Lord Rayleigh (John William Strutt), is the (dominantly) elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. Rayleigh scattering does not change the state of material and is, hence, a parametric process. The particles may be individual atoms or molecules. It can occur when light travels through transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency.
Mie scattering
The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere. The solution takes the form of an infinite series of spherical multipole partial waves. It is named after Gustav Mie. The term "Mie solution" is also used for solutions of Maxwell's equations for scattering by stratified spheres or by infinite cylinders, or other geometries where one can write separate equations for the radial and angular dependence of solutions. The term "Mie theory" is sometimes used for this collection of solutions and methods; it does not refer to an independent physical theory or law.
Rayleigh sky model
The Rayleigh sky model describes the observed polarization pattern of the daytime sky. Within the atmosphere Rayleigh scattering of light from air molecules, water, dust, and aerosols causes the sky's light to have a defined polarization pattern. The same elastic scattering processes cause the sky to be blue. The polarization is characterized at each wavelength by its degree of polarization, and orientation (the e-vector angle, or scattering angle). The polarization pattern of the sky is dependent on the celestial position of the sun. While all scattered light is polarized to some extent, light is highly polarized at a scattering angle of 90° from the light source.
Red Sky Poetry Theatre
Red Sky Poetry Theatre was the longest running live weekly poetry series and open mic in Seattle history. Don Wilsun, who previously co-founded Dogtown Poetry Theater with Joe Scozzy, was a driving force in the founding of Red Sky Poetry Theatre. Along with Joe Keppler, Tom Parson, who also started the Bumbershoot Small Press Fair in 1977, and Judith Roche, whose home was used as a meeting place to plan Red Sky Poetry Theatre, Wilsun formed the core of what would become Red Sky Poetry Theatre. Prior to forming Red Sky Poetry Theatre, Wilsun held ad hoc readings which were simply called Poetry Theatre.
Scattering
Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called "diffuse reflections" and unscattered reflections are called "specular" (mirror-like) reflections. Scattering may also refer to particle-particle collisions between molecules, atoms, electrons, photons and other particles.
Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Skyglow
Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution. While usually referring to sky luminance arising from artificial lighting, skyglow may also involve any nighttime sources of diffuse light, including natural ones like the zodiacal light, starlight, and airglow. In the context of light pollution, skyglow arises from the use of artificial light sources, including electrical (or rarely gas) lighting used for illumination and advertisement, and from gas flares.

Chiapas
Chiapas (), officially the Free and Sovereign State of Chiapas (), is one of the 31 states that with Mexico City make up the 32 federal entities of Mexico. It is divided into 124 municipalities as of September 2017 and its capital city is Tuxtla Gutiérrez. Other important population centers in Chiapas include Ocosingo, Tapachula, San Cristóbal de las Casas, Comitán and Arriaga. It is the southernmost state, bordered by the states of Oaxaca to the west, Veracruz to the northwest and Tabasco to the north, and by the Petén, Quiché, Huehuetenango and San Marcos departments of Guatemala to the east and southeast.
Jax Teller
Jackson Nathaniel "Jax" Teller was a fictional character and the protagonist on the FX television series "Sons of Anarchy", played by British actor Charlie Hunnam. He was the President of the Sons of Anarchy Motorcycle Club's Redwood Original (SAMCRO) mother chapter based in Charming, California. Until the end of season four, he was the Vice President of the club. He has a number of tattoos, most notably his club's logo on his back, a tribute to his father John Teller on his right arm, his son Abel's name on his chest, and his second son, also the name of his deceased brother, Thomas on his left arm.
Funeral
A funeral is a ceremony connected with the burial, cremation, etc. of the body of a dead person, or the burial (or equivalent) with the attendant observances. Funerary customs comprise the complex of beliefs and practices used by a culture to remember and respect the dead, from interment itself, to various monuments, prayers, and rituals undertaken in their honor. Customs vary widely both between cultures and between religious groups and denominations within cultures. Common secular motivations for funerals include mourning the deceased, celebrating their life, and offering support and sympathy to the bereaved.
Roman Republic
The Roman Republic (; ) was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world. Roman government was headed by two consuls, elected annually by the citizens and advised by a senate composed of appointed magistrates. As Roman society was very hierarchical by modern standards, the evolution of the Roman government was heavily influenced by the struggle between the patricians, Rome's land-holding aristocracy, who traced their ancestry to the founding of Rome, and the plebeians, the far more numerous citizen-commoners.
Clothing in ancient Rome
Clothing in ancient Rome generally comprised a short-sleeved or sleeveless, knee-length tunic for men and boys, and a longer, usually sleeved tunic for women and girls. On formal occasions, adult male citizens could wear a woolen toga, draped over their tunic, and married citizen women wore a woolen mantle, known as a palla, over a stola, a simple, long-sleeved, voluminous garment that hung to midstep. Clothing, footwear and accoutrements identified gender, status, rank and social class, and thus offered a means of social control. This was probably most apparent in the segregation of seating tiers at public theatres, games and festivals.
Iroquois
The Iroquois ( or ) or Haudenosaunee () are a historically powerful northeast Native American confederacy. They were known during the colonial years to the French as the "Iroquois League", and later as the "Iroquois Confederacy", and to the English as the "Five Nations" (before 1722), and later as the "Six Nations", comprising the Mohawk, Onondaga, Oneida, Cayuga, Seneca, and Tuscarora peoples. The Iroquois have absorbed many other peoples into their cultures as a result of warfare, adoption of captives, and by offering shelter to displaced peoples. The historic Erie, Susquehannock, Wyandot (Huron), and St. Lawrence Iroquoians, all independent peoples, spoke Iroquoian languages.
