Steve Taylor &amp; The Perfect Foil
Steve Taylor & The Perfect Foil is an American alternative rock supergroup formed in 2010 by singer Steve Taylor with drummer Peter Furler (Newsboys, Peter Furler Band), guitarist Jimmy Abegg (Vector, A Ragamuffin Band), and bassist John Mark Painter (Fleming and John). Taylor formerly saw success as a new wave singer during the 1980s and early 1990s, and also fronted the short-lived band Chagall Guevara. However, by the mid-1990s he abandoned performing music and transitioned into work as a record producer, songwriter, and film-maker. In 2010 Taylor, who was frustrated at the slow pace of his fundraiser for his feature film "Blue Like Jazz", collaborated with Furler, Abegg, and Painter to record the song "A Life Preserved" for the film's soundtrack, and began recording other material.
Blue Bridge (Reed College)
The Blue Bridge, also known as the Cross Canyon Bridge, is a curved pedestrian and bicycle bridge connecting the north and south halves of the Reed College campus in Portland, Oregon, in the United States. The bridge crosses Reed Lake, located within the 28-acre watershed on campus known as the "canyon"; this includes part of the course of Crystal Springs Creek, a tributary of Johnson Creek. The Blue Bridge, completed in 1992, marks the third in a series of bridges that have been commonly referred to as the "cross canyon bridges", signifying their function on campus. The Blue Bridge replaced the Arthur M. Churchill Memorial Bridge, completed in 1959 as a replacement for a flat wooden bridge constructed in the 1930s.

Nandhini is an Indian multilingual supernatural television drama that premiered on 23 January 2017 on Sun TV, Gemini TV, Surya TV and Udaya TV channels. This is the first South Indian Serial to be aired in 4 South Indian language by Sun Network channels and same time except for Udaya TV, which is half hour earlier. It is claimed that the show is the second biggest budgeted series on Indian television after Naagin and the first in South India. Nithya Ram, Malavika Wales, Rahul Ravi and Adhitri are the main protagonists of the series. The series is produced by Tamil film director Sundar C. and his wife, actress Kushboo.
Blue Like Jazz
Blue Like Jazz is the second book by Donald Miller. This semi-autobiographical work, subtitled "Non-Religious Thoughts on Christian Spirituality," is a collection of essays and personal reflections chronicling the author's growing understanding of the nature of God and Jesus, and the need and responsibility for an authentic personal response to that understanding. Much of the work centers on Miller's experiences with friends and fellow students while auditing courses at Reed College, a liberal arts college in Portland, Oregon. The book deals with inward spiritual dealings as Don, his friends Penny, Laura and others struggle with finding meaning in life and the ultimate battle with God ending with choosing him or choosing one's self.
List of recurring The Simpsons characters
"The Simpsons" includes a large array of supporting characters: co-workers, teachers, family friends, extended relatives, townspeople, local celebrities, fictional characters within the show, and even animals. The writers originally intended many of these characters as one-time jokes or for fulfilling needed functions in the town. A number of them have gained expanded roles and have subsequently starred in their own episodes. According to the creator of "The Simpsons", Matt Groening, the show adopted the concept of a large supporting cast from the Canadian sketch comedy show "Second City Television".
List of Sgt. Frog characters
The following is a list of various characters in the fictional universe of the anime and manga series Sgt. Frog and related works. The is led by Sergeant Keroro. While most platoons contain thirty or forty soldiers, the Keroro Platoon only has a meager five. Its full name is the . In the English dub of the anime, the unit is referred to as the Advance Recon Mission Preparatory Invasion Terror Platoon (A.R.M.P.I.T.). Keroro refers to the acronym as being "unfortunate". The initial operation of the Keroro Platoon was to stealthily survey Earth and relay information to the awaiting Keron Invasion Army.
Oldsmobile V8 engine
The Oldsmobile V8 refers to a series of Oldsmobile engines beginning with the advanced 1949 Rocket which were, along with the 1949 Cadillac V8, the first post-war OHV V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, finally adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were manufactured at plants in Lansing, Michigan. All Oldsmobile V8s use a 90° bank angle, and most share a common stroke dimension: for early Rockets, for later Generation 1 engines, and for Generation 2 starting in 1964.

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.
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.
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.
Eye color
Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering.
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.
Raman scattering
Raman scattering or the Raman effect is the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels. It was discovered by C. V. Raman and K. S. Krishnan (who was a student of C.V. Raman) in liquids,  and independently by Grigory Landsberg and Leonid Mandelstam in crystals. The effect had been predicted theoretically by Adolf Smekal in 1923. When photons are scattered from an atom or molecule, most of them are elastically scattered (Rayleigh scattering), such that the scattered photons have the same energy (frequency and wavelength) as the incident photons.

Color theory
In the visual arts, color theory or colour theory is a body of practical guidance to color mixing and the visual effects of a specific color combination. There are also definitions (or categories) of colors based on the color wheel: primary color, secondary color and tertiary color. Although color theory principles first appeared in the writings of Leone Battista Alberti (c.1435) and the notebooks of Leonardo da Vinci (c.1490), a tradition of "colory theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color ("Opticks", 1704) and the nature of primary colors.
Transparency and translucency
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without being scattered. On a macroscopic scale (one where the dimensions investigated are much, much larger than the wavelength of the photons in question), the photons can be said to follow Snell's Law. Translucency (also called translucence or translucidity) is a superset of transparency: it allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell's law; the photons can be scattered at either of the two interfaces where there is a change in index of refraction, or internally.
Primary color
A set of primary colors is, most tangibly, a set of "real" physical pigmented media or colored lights that can be combined in varying amounts to produce a "gamut" of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors are predicted by applying the appropriate mixing model (additive, subtractive, additive averaging etc.) that embodies the underlying physics of how light interacts with the media and ultimately the retina.
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.
Level sensor
Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak. The substance to be measured can be inside a container or can be in its natural form (e.g., a river or a lake). The level measurement can be either continuous or point values. Continuous level sensors measure level within a specified range and determine the exact amount of substance in a certain place, while point-level sensors only indicate whether the substance is above or below the sensing point.
Heat capacity
Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change. The unit of heat capacity is joule per kelvin formula_1, or kilogram metre squared per kelvin second squared formula_2 in the International System of Units (SI). The dimensional form is . Specific heat is the amount of heat needed to raise the temperature of one kilogram of mass by 1 kelvin. Heat capacity is an extensive property of matter, meaning that it is proportional to the size of the system. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample.
Complementary colors
Complementary colors are pairs of colors which, when combined, cancel each other out. This means that when combined, they produce a gray-scale color like white or black. When placed next to each other, they create the strongest contrast for those particular two colors. Due to this striking color clash, the term opposite colors is often considered more appropriate than "complementary colors". Which pairs of colors are considered complementary depends on the color theory one uses:  On the traditional color wheel developed in the 18th century, used by Claude Monet and Vincent van Gogh and other painters, and still used by many artists today, the primary colors were considered to be red, yellow, and blue, and the primary–secondary complementary pairs are red–green (Christmas), blue-orange (Westwood), and yellow–purple (Mesa High).
