Visible spectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz. The spectrum does not, however, contain all the colors that the human eyes and brain can distinguish. Unsaturated colors such as pink, or purple variations such as magenta, are absent, for example, because they can be made only by a mix of multiple wavelengths.
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.
Color vision
Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. Colors can be measured and quantified in various ways; indeed, a person's perception of colors is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with the several types of cone cells in the eye. In essence, different people see the same illuminated object or light source in different ways. Isaac Newton discovered that white light, after being split into its component colours when passed through a dispersive prism, could, by passing them through a different prism, be recombined to make white light.
Color blindness
Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Color blindness can make some educational activities difficult. Buying fruit, picking clothing, and reading traffic lights can be more challenging, for example. Problems, however, are generally minor and most people adapt. People with total color blindness, however, may also have decreased visual acuity and be uncomfortable in bright environments. The most common cause of color blindness is an inherited fault in the development of one or more of the three sets of color sensing cones in the eye.
Purple
Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue. According to surveys in Europe and the U.S., purple is the color most often associated with royalty, magic, mystery and piety. When combined with pink, it is associated with eroticism, femininity and seduction. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops.
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.
Electromagnetic spectrum
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end.

Hindley–Milner type system
In type theory and functional programming, Hindley–Milner (HM), also known as Damas–Milner or Damas–Hindley–Milner, is a classical type system for the lambda calculus with parametric polymorphism, first described by J. Roger Hindley and later rediscovered by Robin Milner. Luis Damas contributed a close formal analysis and proof of the method in his PhD thesis. Among HM's more notable properties are its completeness and its ability to deduce the most general type of a given program without the need of any type annotations or other hints supplied by the programmer. Algorithm W is a fast algorithm, performing type inference in almost linear time with respect to the size of the source, making it practically useful to type large programs.
RGB color model
The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. RGB is a "device-dependent" color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time.
Burmese language
The Burmese language (, MLCTS: "mranmabhasa", IPA: ) is the official language of Myanmar. Although the Constitution of Myanmar officially recognizes the English name of the language as the Myanmar language, most English speakers continue to refer to the language as Burmese. In 2007, it was spoken as a first language by 34 million, primarily the Bamar (Burman) people and related ethnic groups, and as a second language by 10 million, particularly ethnic minorities in Myanmar and neighboring countries. Burmese is a tonal, pitch-register, and syllable-timed language, largely monosyllabic and analytic, with a subject–object–verb word order.

Quantified self
The Quantified Self, also known as lifelogging, is a specific movement by Gary Wolf and Kevin Kelly from Wired magazine, which began in 2007 and tries to incorporate technology into data acquisition on aspects of a person's daily life. People collect data in terms of food consumed, quality of surrounding air, mood, skin conductance as a proxy for arousal, pulse oximetry for blood oxygen level, and performance, whether mental or physical. Wolf has described quantified self is "self-knowledge through self-tracking with technology". People choose to wear self-monitoring and self-sensing sensors (e.g.
Organizational learning
Organizational learning is the process of creating, retaining, and transferring knowledge within an organization. An organization improves over time as it gains experience. From this experience, it is able to create knowledge. This knowledge is broad, covering any topic that could better an organization. Examples may include ways to increase production efficiency or to develop beneficial investor relations. Knowledge is created at four different units: individual, group, organizational, and inter organizational. The most common way to measure organizational learning is a learning curve. Learning curves are a relationship showing how as an organization produces more of a product or service, it increases its productivity, efficiency, reliability and/or quality of production with diminishing returns.
Bound variable pronoun
A bound variable pronoun (also called a bound variable anaphor or BVA) is a pronoun that has a quantified determiner phrase (DP) – such as "every", "some", or "who" – as its antecedent. An example of a bound variable pronoun in English is given in (1). In (1), the quantified DP is each manager, and the bound variable pronoun is him. This pronoun is a bound variable pronoun because it does not refer to one single entity in the world. Rather, its reference varies depending on which entities are encompassed by the phrase "each manager". For example, if "each manager" encompasses both "John" and "Adam", then "him" will refer variably to both "John" and "Adam".

Holography
Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium.

Hard and soft light
Hard and soft light are different types of lighting that are commonly used in photography and filmmaking. Soft light refers to light that tends to "wrap" around objects, casting diffuse shadows with soft edges. Soft light is when a light source is large relative to the subject; hard light is when the light source is small relative to the subject. The hardness or softness of light depends mostly on the following two factors:  The softness of a light source can also be determined by the angle between the illuminated object and the 'length' of the light source (the longest dimension that is perpendicular to the object being lit).
Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic waves, are superimposed causing the phenomenon of interference in order to extract information. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, velocimetry, and optometry. Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities.
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.
Spacetime
In physics, spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive "where" and "when" events occur. Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe (its description in terms of locations, shapes, distances, and directions) was distinct from time (the measurement of when events occur within the universe). However, Albert Einstein's 1905 "special theory of relativity" postulated that the speed of light through empty space has one definite value—a constant—that is independent of the motion of the light source.
Microscopy
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy).

Violet (color)
Violet is the color at the end of the visible spectrum of light between blue and the invisible ultraviolet. Violet color has a dominant wavelength of approximately 380-450 nanometers. Light with a shorter wavelength than violet but longer than X-rays and gamma rays is called ultraviolet. In the color wheel historically used by painters, it is located between blue and purple. On the screens of computer monitors and television sets, a color which looks similar to violet is made, with the RGB color model, by mixing red and blue light, with the blue twice as bright as the red. This is not true violet, since it is composed of multiple longer wavelengths rather than a single wavelength shorter than that of blue light.
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.
Purple
Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue. According to surveys in Europe and the U.S., purple is the color most often associated with royalty, magic, mystery and piety. When combined with pink, it is associated with eroticism, femininity and seduction. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops.
Violet budgerigar mutation
The violet budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is one of the constituent mutations of the violet variety. The violet factor produces a visual effect in any bird which carries it. The effect depends on whether the violet factor is single or double and whether the dark and blue mutations are present. In total there are 18 visually different combinations of these three mutations. However, only three of these approximate to the colour specified by the visual violet exhibition standard. The World Budgerigar Organisation has established precise standards for some budgerigar body colours using the Pantone Codes.
List of Downton Abbey characters
This is a list of characters from Downton Abbey, a British period drama television series created by Julian Fellowes and co-produced by Carnival Films and Masterpiece for ITV and PBS, respectively. Robert Crawley, The 7th Earl of Grantham (also known as Lord Grantham) (played by Hugh Bonneville) was born in 1866 at Downton Abbey. His parents are the late 6th Earl of Grantham and the Dowager Countess of Grantham, Violet Crawley. He has a sister named Rosamund. Despite the family's financial situation, Robert's education was privileged and he was tutored from ages 7 to 13, before attending Eton and then Christ Church, Oxford, where he studied philosophy.
Red-violet
Red-violet is a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red. It is classified in color theory as one of the purple colors—a non-spectral color between red and violet that is a deep version of a color on the line of purples on the CIE chromaticity diagram. Both its saturation and brightness falling short of 100%, red-violet is not a pure chroma. There is a color of similar hue that, however, comes close to being a pure chroma: process magenta. The pure chroma color composed of equal parts of magenta and red is called rose. In the use by artists, red-violet is equivalent to purple, however, although the color "purple" is inaccurately used by many people as a synonym for violet or a color close to violet, professional artists who use the RYB color wheel generally use the term "purple" to specifically refer to a pigment color that is equivalent to red-violet (i.e., the tertiary color between violet and red on the RYB color wheel) in order to give themselves a larger and more balanced palette of pigments to work with.
Violet-green swallow
The violet-green swallow ("Tachycineta thalassina") is a small North American passerine bird in the swallow family. These aerial insectivores are distributed along the west coast from Alaska to Mexico, extending as far east as Montana and Texas. With an appearance very similar to the tree swallow, these individuals can be identified by the white rump side-patches that appear to separate their green back and purple tail. Violet-green swallows are secondary cavity nesters, found in a number of habitats including deciduous and coniferous forests. In addition to nesting in tree holes within these habitats, they are also widely observed nesting in the cracks of large cliffs.

Creativity
Creativity is a phenomenon whereby something new and somehow valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition, or a joke) or a physical object (such as an invention, a literary work, or a painting). Scholarly interest in creativity involves many definitions and concepts pertaining to a number of disciplines: engineering, psychology, cognitive science, education, philosophy (particularly philosophy of science), technology, theology, sociology, linguistics, business studies, songwriting, and economics, covering the relations between creativity and general intelligence, mental and neurological processes, personality type and creative ability, creativity and mental health; the potential for fostering creativity through education and training, especially as augmented by technology; the maximization of creativity for national economic benefit, and the application of creative resources to improve the effectiveness of teaching and learning.

Cassou, a French-born American citizen, is internationally known for her groundbreaking work of using painting as a tool for self-discovery, and for exploring the spiritual dimensions of the creative process. The method that she developed to access spontaneous creativity is now known as "Point Zero Painting". She is the author of Point Zero, Creativity Without Limits, Kids Play, Igniting Children's Creativity and Teachers That Dare, Using the Creative Process to Teach the Creative Process. She is the co-author of Life Paint and Passion, Reclaiming the Magic of Spontaneous Expression.
Expressive therapy
Expressive therapy, also known as the expressive therapies, expressive arts therapy or creative arts therapy, is the use of the creative arts as a form of therapy. Unlike traditional art expression, the process of creation is emphasized rather than the final product. Expressive therapy is predicated on the assumption that people can heal through use of imagination and the various forms of creative expression. Expressive therapy is an umbrella term. Some common types of expressive therapy include:  Horticultural therapy is often not listed with other expressive therapies; it is not universally considered a form of expressive therapy or creative arts therapy.
Painting
Painting is the practice of applying paint, pigment, color or other medium to a solid surface (support base). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. Painting is a mode of creative expression, and the forms are numerous. Drawing, gesture (as in gestural painting), composition, narration (as in narrative art), or abstraction (as in abstract art), among other aesthetic modes, may serve to manifest the expressive and conceptual intention of the practitioner. Paintings can be naturalistic and representational (as in a still life or landscape painting), photographic, abstract, narrative, symbolistic (as in Symbolist art), emotive (as in Expressionism), or political in nature (as in Artivism).
