A polarity chron, or chron, is the time interval between polarity reversals of Earth's magnetic field. It is a term used in stratigraphy (a branch of geology) to name the time interval represented by a magnetostratigraphic polarity unit. It represents a certain time period in geologic history where the Earth's magnetic field was in predominately a "normal" or "reversed" position. Chrons are numbered in order starting from today and increasing in number into the past. As well as a number, each chron is divided into two parts, labelled "n" and "r", thereby showing the position of the field's polarity. A chron is the time equivalent to a chronozone or a polarity zone.It is called a "polarity subchron" when the interval is less than 200,000 years long.

Polarornis is a genus of prehistoric bird, possibly a anserimorph. It contains a single species Polarornis gregorii known from incomplete remains of one individual found on Seymour Island, Antarctica, in rocks which are dated to the Late Cretaceous (López de Bertodano Formation, about 66 mya).The discovery of Polarornis gregorii was first announced by Sankar Chatterjee in 1989, but he did not describe and officially name the species until 2002.

Polarization in astronomy

Polateli (Turkish: Gulduzu, Kurdish: Spenaq‎) is a district and city of Kilis Province of Turkey.

Polarization-division multiple access (PDMA) is a channel access method used in some cellular networks. Separate antennas are used in this type, each with different polarization and followed by separate receivers, allowing simultaneous regional access of satellites.Each corresponding ground station antenna needs to be polarized in the same way as its counterpart in the satellite. This is generally accomplished by providing each participating ground station with an antenna that has dual polarization. The frequency band allocated to each antenna beam can be identical because the uplink signals are orthogonal in polarization. This technique allows frequency reuse.

Polarization is an important phenomenon in astronomy. The polarization of starlight was first observed by the astronomers William Hiltner and John S. Hall in 1949. Subsequently, Jesse Greenstein and Leverett Davis, Jr. developed theories allowing the use of polarization data to trace interstellar magnetic fields. Though the integrated thermal radiation of stars is not usually appreciably polarized at source, scattering by interstellar dust can impose polarization on starlight over long distances. Net polarization at the source can occur if the photosphere itself is asymmetric, due to limb polarization. Plane polarization of starlight generated at the star itself is observed for Ap stars (peculiar A type stars).[1]Both circular and linear polarization of light from the Sun has been measured. Circular polarization is mainly due to transmission and absorption effects in strongly magnetic regions of the Sun's surface. Another mechanism that gives rise to circular polarization is the so-called alignment-to-orientation mechanism. Continuum light is linearly polarized at different locations across the face of the Sun (limb polarization) though taken as a whole, this polarization cancels. Linear polarization in spectral lines is usually created by anisotropic scattering of photons on atoms and ions which can themselves be polarized by this interaction. The linearly polarized spectrum of the Sun is often called the second solar spectrum. Atomic polarization can be modified in weak magnetic fields by the Hanle effect. As a result, polarization of the scattered photons is also modified providing a diagnostics tool for understanding stellar magnetic fields.Polarization is also present in radiation from coherent astronomical sources due to the Zeeman effect (e.g. hydroxyl or methanol masers), and incoherent sources such as the large radio lobes in active galaxies, and pulsar radio radiation (which may, it is speculated, sometimes be coherent). Apart from providing information on sources of radiation and scattering, polarization also probes the interstellar magnetic field in our Galaxy as well as in radio galaxies via Faraday rotation. In some cases it can be difficult to determine how much of the Faraday rotation is in the external source and how much is local to our own Galaxy, but in many cases it is possible to find another distant source nearby in the sky; thus by comparing the candidate source and the reference source, the results can be untangled.The polarization of the cosmic microwave background (CMB) is also being used to study the physics of the very early universe. CMB exhibits 2 components of polarization: B-mode (divergence-free like magnetic field) and E-mode (curl-free gradient-only like electric field) polarization. The BICEP2 telescope located at the South Pole helped in the detection of B-mode polarization in the CMB. The polarization modes of the CMB may provide more information about the influence of Gravitational Waves on the development of the early universe.It has been suggested that astronomical sources of polarised light caused the chirality found in biological molecules on Earth.

Polarization is a property of light waves that describes the orientation of their oscillations. Polarized light pollution is a subset of the various forms of light pollution referring specifically to polarized light.In nature, water and water vapor polarize the sunlight (which itself is slightly polarized). By receiving the direction of polarized photons, some species can correct their course during migration. Artificial polarization of natural or artificial light can disrupt the behavior of these species and the ecosystems in which these species play an important role. Pollination is one example of this.

Polarization spectroscopy comprises a set of spectroscopic techniques based on polarization properties of light (not necessarily visible one; UV, X-ray, infrared, or in any other frequency range of the electromagnetic radiation). By analyzing the polarization properties of light, decisions can be made about the media that emitted the light (or the media the light passes/scatters through).

Polaroscyphus is a genus of fungi within the Hyaloscyphaceae family. This is a monotypic genus, containing the single species Polaroscyphus spetsbergianus.

Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string (see image); for example, in a musical instrument like a guitar string.

Polaroid Type 55 film is a black-and-white peel-apart Polaroid film that yields both a positive print and a negative image that can be used to create enlargements.The film speed is given by the manufacturers as 50 ISO, however that applies only to the positive component. The negative is rated by Polaroid as 25 ISO though it is possible to rate the negative at 32 ISO).After processing the film is peeled apart to reveal positive and negative images. To prevent fading and physical damage the positive image requires a protective coating (included in the box) while the negative requires a clearing solution: Polaroid recommends an 18% Sodium-Sulfite solution but some users favour Kodak's Hypo-Clear works). Polaroid also recommends a hardening fixative to protect the negative from scratches as Type 55 negatives are thin compared to other 4x5" negatives, and the emulsion is extremely delicate.These negatives are fine-grained, have a broad tonal range and are of extremely high resolution, on the order of 150 LP/mm, can create large prints and are suitable for contact printing, particularly involving Cyanotype and Van Dyke brown to create 'blueprint' and 'sepia' prints respectively.Polaroid Type 55 (like all Type 50 series film) requires a Polaroid Model 545 Film Packet Back. This is mounted onto the back of a camera, usually a large format 4x5 inch type, in place of a conventional film carrier. A self-contained waterproof transparent sleeve containing positive and negative film sheets and a small reservoir of reagent gel is inserted into the Packet Back, an exposure made and the Packet Back is removed. By flipping a lever and withdrawing the sleeve the gel is squeezed between the negative and positive emulsion layers. After the set time the layers can be peeled apart. some gel is retained at the edges, creating positive and negative images.A consequence of the process is an impression of a frame on the unprotected negative. The result (a perfect negative surrounded by imperfect frame-like image on three sides, the fourth showing an impression of connective mesh) creates a distinctive "Polaroid frame look" that became popular, so much so photographers who did not use large format cameras (or any kind of chemical process) graphically combine a conventional photographic image, however created, with a superimposed image of an original 'Polaroid frame' as a graphic effect.In 2001 Polaroid filed for bankruptcy protection, and in February 2008 announced it would cease production of all instant film, filing for bankruptcy protection a second time.In 2009 the business was sold, the new owners announcing instant film production would be licensed out to a smaller company. The chemicals needed to process Polaroid instant film had been stockpiled in case of this eventuality but the licensees announced their intention to redesign and manufacture film on a limited basis under the Polaroid brand that would be compatible with most Polaroid film cameras, using machinery left over from a liquidated factory in the Netherlands. In response, in November 2009, Polaroid announced its intention to relaunch the manufacture of Polaroid film cameras in 2010 on a limited basis, marketed to enthusiasts and contingent on the availability of the newly licensed film stock. Initial plans are to produce a black-and-white film to replace existing film stocks, followed by a color film.Stocks of existing Polaroid Type 55 film are scheduled to expire in 2010.

The Polaroid i-Zone was a type of instant film camera manufactured by the Polaroid Corporation starting in 1999. This camera took pictures 1.5"x1", that came on a pull-out strip of paper. The strip was decorated and could later be cut to the size of the photo when the image was finished developing. Special film that had a sticky back for mounting the prints was also available. The camera was mostly marketed at children with its simple functionality, low-cost, and oblong shape. Unusually, the shutter was not mounted behind the lens, but rather perpendicular to the lens, hovering just above the film. A mirror behind the lens would project the picture through the shutter onto the film below. One major marketing point for the camera was its ease of use: the camera had only three aperture settings, selected by a lever that pointed to a picture representing when each setting would be appropriate, be it indoors, outdoors on a sunny day, or outdoors on a cloudy day. After taking a photo, the lever would automatically revert to the off position to save power. Film for this camera was discontinued in 2006.

Economists refer to the polarization of the labor force when middle-class jobs—requiring a moderate level of skills, like autoworkers’ jobs—seem to disappear relative to those at the bottom, requiring few skills, and those at the top, requiring greater skill levels. The structure of job opportunities in the United States has sharply polarized over the past two decades, with expanding job opportunities in both high-skill, high-wage occupations and low-skill, low wage occupations, coupled with contracting opportunities in middle-wage, middle-skill white-collar and blue-collar jobs. Although this has contributed to the rise of income inequality in the U.S. it is a minor factor compared to the relatively rapid rise in income and wealth by the top 1%. Although income and wealth inequality are uniquely American phenomena. of the past decades in industrialized countries, employment and economic polarization is widespread across industrialized economies; it is not a uniquely American phenomenon. Over the past decades, wage gains were also polarized, with modest gains at the extremes and smaller gains in the middle. A good description of polarization in Great Britain is one of the first uses of the term, economic polarization.

In linguistics, a polarity item is a lexical item that can appear only in environments associated with a particular grammatical polarity – affirmative or negative. A polarity item that appears in affirmative (positive) contexts is called a positive polarity item (PPI), and one that appears in negative contexts is a negative polarity item (NPI).The environment in which a polarity item is permitted to appear is called a "licensing context". In the simplest case, an affirmative statement provides a licensing context for a PPI, while negation provides a licensing context for an NPI. However, there are many complications, and not all polarity items of a given type need necessarily have exactly the same set of licensing contexts.

A polarization rotator is an optical device that rotates the polarization axis of a linearly polarized light beam by an angle of choice. Such devices can be based on the Faraday effect, on birefringence, or on total internal reflection. Rotators of linearly polarized light have found widespread applications in modern optics since laser beams tend to be linearly polarized and it is often necessary to rotate the original polarization to its orthogonal alternative.

In electrochemistry, polarization is a collective term for certain mechanical side-effects (of an electrochemical process) by which isolating barriers develop at the interface between electrode and electrolyte. These side-effects influence the reaction mechanisms, as well as the chemical kinetics of corrosion and metal deposition. in a reaction we can displace the bonding electrons by attacking reagents.

Polaroid film

A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy).To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low-cost eyeglasses which contain a pair of different polarizing filters. As each filter passes only that light which is similarly polarized and blocks the light polarized in the opposite direction, each eye sees a different image. This is used to produce a three-dimensional effect by projecting the same scene into both eyes, but depicted from slightly different perspectives. Multiple people can view the stereoscopic images at the same time.

Some Polaroid instant films are suitable for various forms of alternative processing leading to artistic effects. One form was the manipulation of SX-70 using various tools before the emulsion dried to create an oil painting effect. However, SX-70 is no longer in production and similar films by the Polaroid Originals do not have the same manipulable qualities.Emulsion lifting can be achieved by soaking Polaroid, Fuji peel-apart, and some Impossible Project's films in water and then transferring the emulsion to a new surface like wood, metal or paper.Image transfers are another method of transferring the image from instant peel-apart film to a new surface. Image transfers are done by peeling the negative positive sandwich apart early in development and pushing the wet negative side down firmly onto a sheet of print-making paper and applying an even pressure with a roller transferring it to the new surface.

Polarization ripples are parallel oscillations which have been observed since the 1960s on the bottom of pulsed laser irradiation of semiconductors. They have the property to be very dependent to the orientation of the laser electric field.Since the wide availability of femtosecond lasers, such structures have been observed on metals, semiconductors, but also on dielectrics. Moreover, the ripples can reach far sub-wavelength periodicities until 100 nm as recently observed in titanium. The "cumulative" changes occurring from pulse to pulse in the material properties are still under investigation.

In reflection seismology, a polarity reversal or phase change is a local amplitude seismic attribute anomaly that can indicate the presence of hydrocarbons and is therefore known as a direct hydrocarbon indicator. It primarily results from the change in polarity of the seismic response when a shale (with a lower acoustic impedance) overlies a brine-saturated zone (with a high acoustic impedance), that becomes invaded with an oil/gas sand (with the lowest acoustic impedance of the three). This changes the acoustic impedance contrast from an increase to a decrease, resulting in the polarity of the seismic response being reversed - as per the normal convention adopted by the SEG.

Polarity is a board game that requires strategic thinking and dexterity to control hovering magnetic discs. Polarity was invented in 1985 by Canadian artist and designer Douglas Seaton. It was first published in 1986. The game has had a tumultuous past, with its rights changing hands several times over the past two decades. The game has been published by Telemotion Technologies, Irwin Toy, briefly with Mattel and most recently by Temple Games. The game ships in a canvas sleeve and include the magnets, the board, and a paper rulebook. An unrelated game of the same name is published by a company called Mindwalk (Company).The purpose of the game is to gain points by forming towers of discs. The playing pieces are magnetic discs, with one side white and the other black, north and south respectively. They are identical with the exception of a neutral central disc which is coloured red.Play starts with one player tossing the central red disc in order to determine which player plays with which colour/magnetic polarity. Each player then lays 5 'foundation discs' of their colour starting with the white player. Each disc can be placed on the playing area with no limitation other than to be inside the external circle and not touching the red disc.Play then proceeds by placing further discs within the playing area, balanced, leaning, on the magnetic fields of preceding pieces. These pieces are known as 'leaners'. Moves which disrupt the pieces currently in play by making them fall or stick together are known as 'faults', and end a player's turn. If a fault results in two or more pieces touching each other, the opposing player then has an opportunity to capture those pieces by forming them into towers, which at the end of the game score points. Occasionally a player will intentionally fault, causing one of their own pieces to fall flat onto the play surface, thus making it easier to play further pieces.The play ends when one player has exhausted their supply of pieces or if a piece touches the center red disc. The winner of the game is determined by points scored, which are based on the number of pieces in towers of a player's color, and the pieces remaining in the opponent's hand.

A Polarograph is a chemical analysis instrument used to record automatic voltage-intensity curves.The Polarograph uses an electrolytic cell consisting of an electrode or microelectrode small area, generally of mercury drop type , which is a very fine capillary tube through which mercury flows slowly , which comes in the form of small droplets, which fall on the same surface of a much broader element, which is the other electrode . When one applies a variable voltage in this cell, the electrode large area remains unchanged, while the microelectrode undergoes a change of potential ,( i.e. is polarized). It also has a potentiometer coupled to the motor that moves the recording paper so that a certain voltage variation corresponds to a constant length of recording paper, and a galvanometer suitable for measuring the intensity of the electric current, whose response is transmitted to the actuator that moves the needle of the recorder. The technique used is called polarography.

The Polaroid i-Zone was a type of instant film camera manufactured by the Polaroid Corporation starting in 1999. This camera took pictures 1.5"x1", that came on a pull-out strip of paper. The strip was decorated and could later be cut to the size of the photo when the image was finished developing. Special film that had a sticky back for mounting the prints was also available. The camera was mostly marketed at children with its simple functionality, low-cost, and oblong shape.

Polarizing organic photovoltaics (ZOPV) is a concept for harvesting energy from Liquid crystal display screens, developed by engineers from UCLA. This concept enables devices to utilize external light and the LCD screen's backlight using photovoltaic polarizers. Photovoltaic polarizers convert this light into electricity which can be used to power the device. This concept also provides multifunctional capability to devices with LCD screens as they act as photovoltaic devices and also as polarisers.

Gravitation can be described via a scalar theory of gravitation, using a stratified conformally flat metric, in which the field equation arises from the notion that the vacuum behaves like an optical polarizable medium. It was proposed by R. H. Dicke (1957) and then H. E. Puthoff (1998). Harold Puthoff (see also Bernard Haisch and SED)In theoretical physics, polarizable vacuum (PV) and its associated theory refers to proposals by Harold Puthoff, Robert H.

In developmental biology, an embryo is divided into two hemispheres: the animal pole and the vegetal pole within a blastula.The animal pole consists of small cells that divide rapidly, in contrast with the vegetal pole below it. In some cases, the animal pole is thought to differentiate into the later embryo itself, forming the three primary germ layers and participating in gastrulation.The vegetal pole contains large yolky cells that divide very slowly, in contrast with the animal pole above it. In some cases, the vegetal pole is thought to differentiate into the extraembryonic membranes that protect and nourish the developing embryo, such as the placenta in mammals and the chorion in birds.The development of the animal-vegetal axis occurs prior to fertilization. Sperm entry can occur anywhere in the animal hemisphere. The point of sperm entry defines the dorso-ventral axis - cells opposite the region of sperm entry will eventually form the dorsal portion of the body.In the frog Xenopus laevis, a pigment pattern provides the oocyte with features of a radially symmetrical body with a distinct polarity. The animal hemisphere is dark brown, and the vegetal hemisphere is only weakly pigmented. The axis of symmetry passes through on one side the animal pole, and on the other side the vegetal pole. The two hemispheres are separated by an unpigmented equatorial belt. Polarity has a major influence on the emergence of the embryonic structures. In fact, the axis polarity serves as one coordinate of geometrical system in which early embryogenesis is organized.

Polars is the debut album from Dutch metal band, Textures. It was produced, mixed, recorded, and mastered entirely by the band themselves, and was issued on Listenable Records in 2003. The label re-issued the album in 2004 with slightly different cover art (adding images of machinery and gears) and in some cases, a different casing.The album contained eight songs, the final two being the two longest songs of the album. The sixth and eighth songs are wholly ambient with assorted sound effects. Most of the other tracks bear hallmarks of thrash and progressive metal, with some death metal and hardcore elements. It is also their only album featuring vocalist Pieter Verpaalen, who was replaced by Eric Kalsbeek for their second release.The CD also features the video for Ostensibly Impregnable.

In electrical engineering, dot marking convention, or alphanumeric marking convention, or both, can be used to denote the same relative instantaneous polarity of two mutually inductive components such as between transformer windings. These markings may be found on transformer cases beside terminals, winding leads, nameplates, schematic and wiring diagrams.The convention is that current entering a transformer at the end of a winding marked with a dot, will tend to produce current exiting other windings at their dotted ends.Maintaining proper polarity is important in power system protection, measurement and control systems. A reversed instrument transformer winding may defeat protective relays, give inaccurate power and energy measurements, or result in display of negative power factor. Reversed connections of paralleled transformer windings will cause circulating currents or an effective short circuit. In signal circuits, reversed connections of transformer windings can result in incorrect operation of amplifiers and speaker systems, or cancellation of signals that are meant to add.

Polarization is an important phenomenon in astronomy. The polarization of starlight was first observed by the astronomers William Hiltner and John S. Hall in 1949. Subsequently, Jesse Greenstein and Leverett Davis, Jr. developed theories allowing the use of polarization data to trace interstellar magnetic fields.

In electrochemistry, polarization is a collective term for certain mechanical side-effects (of an electrochemical process) by which isolating barriers develop at the interface between electrode and electrolyte. These side-effects influence the reaction mechanisms, as well as the chemical kinetics of corrosion and metal deposition. in a reaction we can displace the bonding electrons by attacking reagents. The electronic displacement in turn may be due to certain effects,some of which are permanent (inductive and mesomeric effects) and the others are temporary (electromeric effect). those effects which are permanently operating in the molecule,are known as polarization effects. and those effects which are brought into play by attacking reagent and as the attacking reagent is removed,the electronic displacement disappears known as polarisability effects.The term 'polarization' derives from the early 19th-century discovery that electrolysis causes the elements in an electrolyte to be attracted towards one or the other pole— i.e. the gasses were polarized towards the electrodes. Thus, initially 'polarization' was essentially a description of electrolysis itself, and in the context of electrochemical cells used to describe the effects on the electrolyte (which was then called "polarization liquid"). In time, as more electrochemical processes were invented, the term 'polarization' evolved to denote any (potentially undesirable) mechanical side-effects that occur at the interface between electrolyte and electrodes.These mechanical side-effects are:activation polarization: the accumulation of gasses (or other non-reagent products) at the interface between electrode and electrolyte.concentration polarization: uneven depletion of reagents in the electrolyte cause concentration gradients in boundary layers.Both effects isolate the electrode from the electrolyte, impeding reaction and charge transfer between the two. The immediate consequences of these barriers are:the reduction potential decreases, the reaction rate slows and eventually halts.electric current is increasingly converted into heat rather than into desired electrochemical work.as predicted by Ohm's law, either electromotive force decreases and current increases, or vice versa.the self-discharge rate increases in electrochemical cells.Each of these immediate consequences has multiple secondary effects. For instance, heat affects the crystalline structure of the electrode material. This in turn can influence reaction rate, and/or accelerate dendrite formation, and/or deform the plates, and/or precipitate thermal runaway.The mechanical side-effects can be desirable in some electrochemical processes, for example, certain types of electropolishing and electroplating take advantage of the fact that evolved gasses will first accumulate in the depressions of the plate. This feature can be used to reduce current in the depressions, and exposes ridges and edges to higher currents. Undesirable polarization can be suppressed by vigorous agitation of the electrolyte, or – when agitation is impractical (such as in a stationary battery) – with a depolarizer.

A polarity chron, or chron, is the time interval between polarity reversals of Earth's magnetic field. It is a term used in stratigraphy (a branch of geology) to name the time interval represented by a magnetostratigraphic polarity unit. It represents a certain time period in geologic history where the Earth's magnetic field was in predominately a "normal" or "reversed" position. Chrons are numbered in order starting from today and increasing in number into the past.

Polaroids From The Dead

Polarization-division multiplexing (PDM) is a physical layer method for multiplexing signals carried on electromagnetic waves, allowing two channels of information to be transmitted on the same carrier frequency by using waves of two orthogonal polarization states. It is used in microwave links such as satellite television downlinks to double the bandwidth by using two orthogonally polarized feed antennas in satellite dishes. It is also used in fiber optic communication by transmitting separate left and right circularly polarized light beams through the same optical fiber.

Polarizing organic photovoltaics

A polarizing filter or polarising filter (see spelling differences) is often placed in front of the camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea. Since reflections (and sky-light) tend to be at least partially linearly-polarized, a linear polarizer can be used to change the balance of the light in the photograph. The rotational orientation of the filter is adjusted for the preferred artistic effect. For modern cameras, a circular polarizer (product labeling abbreviation: CPL) is typically used; this comprises firstly a linear polarizer which performs the artistic function just described, followed by a quarter-wave plate which further transforms the now-linearly polarized light into circularly-polarised light before entering the camera. This additional step avoids problems with auto-focus and light-metering sensors within some cameras, which otherwise may not function reliably with a simple linear polariser.

Polarornis is a genus of prehistoric bird, possibly a anserimorph. It contains a single species Polarornis gregorii known from incomplete remains of one individual found on Seymour Island, Antarctica, in rocks which are dated to the Late Cretaceous (López de Bertodano Formation, about 66 mya).The discovery of Polarornis gregorii was first announced by Sankar Chatterjee in 1989, but he did not describe and officially name the species until 2002. The name Polarornis had been announced unofficially several years prior to its official publication, in Chatterjee's 1997 book The Rise of Birds.

Pogorzel [pɔˈɡɔʐɛl] (German: Hegelingen) is a village in the administrative district of Gmina Gołdap, within Gołdap County, Warmian-Masurian Voivodeship, in northern Poland, close to the border with the Kaliningrad Oblast of Russia. It lies approximately 15 kilometres (9 mi) south-east of Gołdap and 134 km (83 mi) east of the regional capital Olsztyn.Before 1945 the area was part of Germany (East Prussia). After World War II the region was placed under Polish administration by the Potsdam Agreement under territorial changes demanded by the Soviet Union. Most Germans fled or were expelled and replaced with Poles expelled from the Polish areas annexed by the Soviet Union or forced to settle in the area through Operation Vistula in 1947.

A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy).To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low-cost eyeglasses which contain a pair of different polarizing filters.

Polarization spectroscopy comprises a set of spectroscopic techniques based on polarization properties of light (not necessarily visible one; UV, X-ray, infrared, or in any other frequency range of the electromagnetic radiation). By analyzing the polarization properties of light, decisions can be made about the media that emitted the light (or the media the light passes/scatters through). Alternatively, a source of polarized light may be used to probe a media; in this case, the changes in the light polarization (comparing to the incidental one) allow to infer the media properties.In general, any kind of anisotropy in the media results in some sort of change in polarization. Such an anisotropy can be either inherent to the media (e.g., in the case of a crystal substance), or imposed externally (e.g., in the presence of magnetic field in plasma).

Polarization (racial)

Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string (see image); for example, in a musical instrument like a guitar string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string. In contrast, in longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization. Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, and transverse sound waves (shear waves) in solids. In some types of transverse waves, the wave displacement is limited to a single direction, so these also do not exhibit polarization; for example, in surface waves in liquids (gravity waves), the wave displacement of the particles is always in a vertical plane.An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field which are always perpendicular; by convention, the "polarization" of electromagnetic waves refers to the direction of the electric field. In linear polarization, the fields oscillate in a single direction. In circular or elliptical polarization, the fields rotate at a constant rate in a plane as the wave travels. The rotation can have two possible directions; if the fields rotate in a right hand sense with respect to the direction of wave travel, it is called right circular polarization, or, if the fields rotate in a left hand sense, it is called left circular polarization.Light or other electromagnetic radiation from many sources, such as the sun, flames, and incandescent lamps, consists of short wave trains with an equal mixture of polarizations; this is called unpolarized light. Polarized light can be produced by passing unpolarized light through a polarizing filter, which allows waves of only one polarization to pass through. The most common optical materials (such as glass) are isotropic and do not affect the polarization of light passing through them; however, some materials—those that exhibit birefringence, dichroism, or optical activity—can change the polarization of light. Some of these are used to make polarizing filters. Light is also partially polarized when it reflects from a surface.According to quantum mechanics, electromagnetic waves can also be viewed as streams of particles called photons. When viewed in this way, the polarization of an electromagnetic wave is determined by a quantum mechanical property of photons called their spin. A photon has one of two possible spins: it can either spin in a right hand sense or a left hand sense about its direction of travel. Circularly polarized electromagnetic waves are composed of photons with only one type of spin, either right- or left-hand. Linearly polarized waves consist of equal numbers of right and left hand spinning photons, with their phase synchronized so they superpose to give oscillation in a plane.Polarization is an important parameter in areas of science dealing with transverse waves, such as optics, seismology, radio, and microwaves. Especially impacted are technologies such as lasers, wireless and optical fiber telecommunications, and radar.

The Swinger was especially successful in the youth market due to its low price, stylish appearance, and catchy "Meet the Swinger" jingle.The Swinger featured an extinction exposure meter tied to the aperture which displayed the word "YES" in a window below the viewfinder when the exposure was set correctly. Earlier models also displayed the word "NO" when not properly adjusted, while later units used only the YES indicator. The Swinger also included a built-in flashgun for AG-1 flashbulbs.The Swinger used Polaroid's 20-Series roll film, which was the first Polaroid roll film to develop outside the camera.Variants included the Model M-15 "Swinger Sentinel" (the Swinger II in non-US markets), which was a cheaper Swinger without the built-in flash, and the Model 3000 "Big Swinger", which used 100-Series pack film instead of the old-style picture rolls. The Swinger name was also used on several international-market Polaroid cameras in the 1960s and 1970s.
