Horse

The horse (Equus ferus caballus) is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Hyracotherium, into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated, such as the endangered Przewalski's horse, a separate subspecies, and the only remaining true wild horse. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior.

Horses' anatomy enables them to make use of speed to escape predators and they have a well-developed sense of balance and a strong fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down. Female horses, called mares, carry their young for approximately 11 months, and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under saddle or in harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years.

Horses (album)

Horses is the debut studio album by American musician Patti Smith, released on December 13, 1975 on Arista Records. Smith, a fixture of the then-burgeoning New York punk rock music scene, began recording Horses with her band in 1975 after being signed to Arista Records, with John Cale being enlisted to produce the album. With its fusion of simplistic rock and roll structures and Smith's freeform, Beat poetry-infused lyrics, Horses was met with widespread critical acclaim upon its initial release. Despite a lack of airplay or a popular single to support the album, it nonetheless experienced modest commercial success, managing a top 50 placing on the US Billboard 200.

Horses has since been viewed by critics as one of the greatest and most influential albums in the history of American punk rock movement, as well as one of the greatest albums of all time. Horses has also been cited as a key influence on a number of succeeding punk, post-punk, and alternative rock acts, including Siouxsie and the Banshees, R.E.M., The Smiths, and Garbage.

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. When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visual depth cues such as parallax and perspective that change realistically with any change in the relative position of the observer.

In its pure form, holography requires the use of laser light for illuminating the subject and for viewing the finished hologram. In a side-by-side comparison under optimal conditions, a holographic image is visually indistinguishable from the actual subject, if the hologram and the subject are lit just as they were at the time of recording. A microscopic level of detail throughout the recorded volume of space can be reproduced. In common practice, however, major image quality compromises are made to eliminate the need for laser illumination when viewing the hologram, and sometimes, to the extent possible, also when making it. Holographic portraiture often resorts to a non-holographic intermediate imaging procedure, to avoid the hazardous high-powered pulsed lasers otherwise needed to optically "freeze" living subjects as perfectly as the extremely motion-intolerant holographic recording process requires. Holograms can now also be entirely computer-generated and show objects or scenes that never existed.

This Is Us (Backstreet Boys album)

This Is Us is the seventh studio album, sixth in the United States, from American pop group Backstreet Boys. It is their second and last album as a quartet. It was released on September 30, 2009 in Japan through Sony Music Japan, October 5, 2009 in the UK through RCA, and October 6 in the U.S. as the final studio album through Jive Records.

On the album, the group has reunited with previous collaborator and producer Max Martin (responsible for the previous hit "I Want It That Way") to try and create their best record since their 1999 worldwide hit album Millennium. They worked with Ryan Tedder, Claude Kelly, Jim Jonsin, RedOne, Ne-Yo, Brian Kennedy, Alex James, Pitbull, Eddie Galan, Rami Yacoub, Kristian Lundin, and T-Pain amongst others for the album as well.

The album debuted at number 9 on the US Billboard 200 making them the first group since Sade to have their first seven albums reach top 10 on the chart.RedOne produced the album's lead single "Straight Through My Heart" which was released in August/September 2009 and reached number 1 in Taiwan, number 3 in Japan, number 5 in Spain, number 106 in Billboard Hot 100, 19 in Canada, 72 in the UK, and 18 on the US Hot Dance Club Songs chart. It was their final album under Jive and their last album as a quartet before original member Kevin Richardson rejoined the band in 2012.
