Dark horse

A dark horse is a little-known person or thing that emerges to prominence, especially in a competition of some sort or a contestant that seems unlikely to succeed.

Origin

The term began as horse racing parlance for a race horse that is not known to gamblers and thus is difficult to place betting odds on.

The earliest-known mention of the concept is in Benjamin Disraeli's novel The Young Duke (1831). Disraeli's protagonist, the Duke of St. James, attends a horse race with a surprise finish: "A dark horse which had never been thought of, and which the careless St. James had never even observed in the list, rushed past the grandstand in sweeping triumph."

In the political arena

The concept has been used in political contexts in such countries as Iran,Philippines,Russia,Egypt, and the United States.

Politically, the concept came to America in the nineteenth century when it was first applied to James K. Polk, a relatively unknown Tennessee politician who won the Democratic Party's 1844 presidential nomination over a host of better-known candidates. Polk won the nomination on the ninth ballot at his party's national nominating convention, and went on to become the country's eleventh president as a result of the presidential election.

Katy Perry

Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and actress. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations. After being dropped by The Island Def Jam Music Group and Columbia Records, Perry signed a recording contract with Capitol Records in April 2007.

Perry rose to fame in 2008 with the release of the singles "I Kissed a Girl" – which sparked controversy for its homosexual themes – and "Hot n Cold" from her second album, a pop rock record titled One of the Boys. Her third album, Teenage Dream (2010), ventured into disco, and contained the U.S. Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)" as well as the number-three single "The One That Got Away". The album became the first by a female artist to produce five number-one Billboard Hot 100 songs, and the second overall after Michael Jackson's album Bad. In March 2012, she reissued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake".

Darkness

Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.

Humans are unable to distinguish color when either light or darkness predominate. In conditions of insufficient light, perception is achromatic and ultimately, black.

The emotional response to darkness has generated metaphorical usages of the term in many cultures.

Scientific

Perception

The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.

Physics

In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. For example, a matte black paint does not reflect much visible light and appears dark, whereas white paint reflects much light and appears bright. For more information see color.

Light cannot be absorbed without limit. According to the principle of the conservation of Energy, energy cannot be created or destroyed; it can only be converted from one type to another. Consequently, most objects that absorb visible light reemit it as heat. So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive. For more information see thermodynamics.

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.
