Pharos (album)

Pharos is an album by the experimental ambient group Seti, which was released in 1995.

Track listing

Disc 1: "Arecibo"

Disc 2: "Phoenix"

Notes

The liner notes contain a short introduction to SETI written by Frank Drake, an essay by Madison Blue, and descriptions of the Arecibo message, the Drake equation, Project Phoenix, and a history of SETI in NASA.

The recorded 1974 Arecibo message is also found in the music itself, as are recordings of radio telescopes receiving various types of pulsars. The track ".beacon01" features the voice of Frank Drake giving an introduction to the SETI project.

Pharos (horse)

Pharos (April 4, 1920 – April 30, 1937) was a British bred Thoroughbred racehorse and a Leading sire in Great Britain & Ireland.

Pedigree

Bred and raced by Edward Stanley, 17th Earl of Derby, he was a brother to the stakeswinners, Fair Isle (1927) and Fairway (1925) who won 31 races and £71,635 between them. They were by the successful sire, Phalaris, their dam the staying mare, Scapa Flow by Chaucer. Pharos's maximum distance was approximately 1¼ miles and Fairway could stay much further and was altogether a better racehorse. Both Pharos and Fairway were outstanding successes at stud where they both sired classic winners of a high standard. However, Pharos has proved the more influential in the long run and now stands four-square on the pre-eminent sire line in world racing.

Racing record

Pharos won six of his nine starts at age two and three of his nine starts at age three when he also ran second to Papyrus in the 1923 Epsom Derby. Racing at age four, Pharos won four of seven starts, notably beating Prix de l'Arc de Triomphe winner Parth in the ten furlong Champion Stakes at Newmarket Racecourse. Racing at age five, Pharos did not win in his first four starts but then in the last race of his career, won his second consecutive edition of the Duke of York Handicap by six lengths.

Ion

An ion (/ˈaɪən, -ɒn/) is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.

In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation.

If an atom gains electrons, it has a net negative charge and is known as an anion.

An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion. Because of their electric charges, cations and anions attract each other and readily form ionic compounds, such as salts.

In the case of physical ionization of a medium, such as a gas, what are known as "ion pairs" are created by ion impact, and each pair consists of a free electron and a positive ion.

History of discovery

The word ion is the Greek ἰόν, ion, "going", the present participle of ἰέναι, ienai, "to go". This term was introduced by English physicist and chemist Michael Faraday in 1834 for the then-unknown species that goes from one electrode to the other through an aqueous medium. Faraday did not know the nature of these species, but he knew that since metals dissolved into and entered a solution at one electrode, and new metal came forth from a solution at the other electrode, that some kind of substance moved through the solution in a current, conveying matter from one place to the other.

JPEG

JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.

JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.

The term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.

Ion (DC Comics)

Ion is a fictional character, a DC Comics superhero. Created by writer Judd Winick and artist Dale Eaglesham for Green Lantern vol. 3 #142, Ion was devised as the new superhero identity for Green Lantern protagonist Kyle Rayner. It was later revealed to be able to form mutualism with a host, bestowing its power to a host willingly. This followed a similar retcon as Parallax, originally the new supervillain alias of Hal Jordan, which was revealed to be a parasitic embodiment of fear in the 2004–2005 miniseries Green Lantern: Rebirth.

Fictional character biography

As soon as sentient beings developed willpower, Ion was born from the green wavelength of the so-called "emotional spectrum". Its existence has been kept a secret for eons, and it resided in the Central Battery on Oa to keep Parallax, the parasitic fear entity also imprisoned there, in check, as well as granting the Guardians of the Universe, Manhunters, The Green Glob, Halla's, and then The Green Lantern Corps a portion of its vast powers. After Hal Jordan, under the influences of Parallax and Sinestro, destroyed the Central Battery, Ion, along with Parallax and Sinestro, were set free. After wandering throughout the cosmos, it eventually settled within Kyle Rayner as its host.
