Ray (fish)
Batoidea is a superorder of cartilaginous fishes, commonly known as rays. They and their close relatives, the sharks, comprise the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. Anatomy Batoids are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batoids have five ventral slot-like body openings called gill slits that lead from the gills, but the Hexatrygonidae have six. Batoid gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides of the head. Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed the ...

The Rays
The Rays were an American group formed in New York City in 1955, and active into the early 1960s. They first recorded for Chess Records. Their biggest hit single was "Silhouettes", a moderately-slow doo-wop piece of pop music that reached number 3 on the ''Billboard'' Hot 100 in 1957 on Cameo after being initially released on the small XYZ Records. It sold over one million copies, and was awarded a gold disc. The song was written by Bob Crewe and Frank Slay, Jr. Also on XYZ, they had a minor hit with "Mediterranean Moon" a mid-chart hit with "Magic Moon" (by this time, XYZ was being nationally distributed by London Records). They also recorded the original version of " Daddy Cool", which was used as part of a medley with Little Richard's " The Girl Can't Help It", for the UK band Darts which made number 6 in the UK Singles Chart in 1977. The song also lent its name to the Australian band Daddy Cool, who recorded the song in 1971. "Silhouettes" was also released by The D ...

Rays (Michael Nesmith Album)
''Rays'' is an album by Michael Nesmith, originally released in a limited edition of 100 in November 2005, then later released in an unlimited edition in April 2006. Nesmith described the album as a cinematic journey of sound with elements of swing, jazz and instrumental funk that forms what he calls "New Century Modern". Background The album cover is a comic strip drawn by Drew Friedman and features Nesmith "driving" through five stages of his life, with a quest of looking to fill his "appetite": 1) His earlier career in The Monkees, where he is seen driving a Pontiac GTO and wearing his signature knit-cap; 2) His career as the frontman of the First National Band, driving a Jeep; 3) His ''Elephant Parts''-era career, where he is seen driving a pink Cadillac (referring to his song, "Eldorado to the Moon"); 4) His later life as an author, entrepreneur and philanthropist, driving a Rolls-Royce and asking, "where am I?"; 5) And in the center of the cartoon, Nesmith is sitting pe ...

Ray (optics)
In optics a ray is an idealized geometrical model of light, obtained by choosing a curve that is perpendicular to the ''wavefronts'' of the actual light, and that points in the direction of energy flow. Rays are used to model the propagation of light through an optical system, by dividing the real light field up into discrete rays that can be computationally propagated through the system by the techniques of '' ray tracing''. This allows even very complex optical systems to be analyzed mathematically or simulated by computer. Ray tracing uses approximate solutions to Maxwell's equations that are valid as long as the light waves propagate through and around objects whose dimensions are much greater than the light's wavelength. '' Ray optics'' or '' geometrical optics'' does not describe phenomena such as diffraction, which require wave optics theory. Some wave phenomena such as interference can be modeled in limited circumstances by adding phase to the ray model. Definiti ...

Ray (fish Fin Anatomy)
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Ray (quantum Theory)
In mathematics and the foundations of quantum mechanics, the projective Hilbert space P(H) of a complex Hilbert space H is the set of equivalence classes of non-zero vectors v in H, for the relation \sim on H given by :w \sim v if and only if v = \lambda w for some non-zero complex number \lambda. The equivalence classes of v for the relation \sim are also called rays or projective rays. This is the usual construction of projectivization, applied to a complex Hilbert space. Overview The physical significance of the projective Hilbert space is that in quantum theory, the wave functions \psi and \lambda \psi represent the same ''physical state'', for any \lambda \ne 0. It is conventional to choose a \psi from the ray so that it has unit norm, \langle\psi, \psi\rangle = 1, in which case it is called a normalized wavefunction. The unit norm constraint does not completely determine \psi within the ray, since \psi could be multiplied by any \lambda with absolute value 1 (the U(1) ac ...

Ray (comics)
The Ray is the name of four superheroes in the DC Comics Universe. All versions of the character have the superpower of manipulating visible light in some manner. The first Ray was Langford "Happy" Terrill, a Quality Comics character. When DC Comics later purchased Quality Comics, Happy Terrill was retconned as a member of the Freedom Fighters on Earth-X. The character, created by artist Lou Fine, first appeared in '' Smash Comics'' #14 (Sept 1940) and continued in the book until issue #40 (Feb 1943). Following DC altering much of its continuity and history in the storyline '' Crisis on Infinite Earths'', Happy Terrill was now an inhabitant of the mainstream DC Comics universe and his son Ray Terrill became the second Ray. Later, the character Stan Silver briefly operated as the third hero called the Ray. In 2011's New 52 relaunch of DC Comics, where fictional history was again restructured, a new character called Lucien Gates was introduced as the Ray. Although historic ...

Firefly
The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as an honest warning signal that the larvae were distasteful; this was co-opted in evolution as a mating signal in the adults. In a further development, female fireflies of the genus '' Photuris'' mimic the flash pattern of '' Photinus'' species to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. While all known fireflies glow as larvae, only some species produce light in their adult stage, and the location of the light organ varies among species and between sexes of the same species. Fireflies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
