Lux

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used in both singular and plural.

Explanation

Illuminance

Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance (lux) is inversely proportional to area when the luminous flux (lumens) is held constant.

Falcon

A falcon (/ˈfɔːlkən, ˈfæl-/) is any one of 37 species of raptors in the genus Falco, widely distributed on all continents of the world except Antarctica.

Adult falcons have thin, tapered wings, which enable them to fly at high speed and to change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broadwing. This makes it easier to fly while learning the exceptional skills required to be effective hunters as adults.

The falcons are the largest genus in the Falconinae subfamily of Falconidae, which itself also includes another subfamily comprising caracaras and a few other species. All these birds kill with their beaks, using a "tooth" on the side of their beaks — unlike the hawks, eagles, and other birds of prey in Accipitridae, which use their feet.

Peregrine falcons have been recorded diving at speeds of 200 miles per hour (320 km/h), making them the fastest-moving creatures on Earth. Other falcons include the gyrfalcon, lanner falcon, and merlin. Some small falcons with long, narrow wings are called hobbies, and some which hover while hunting are called kestrels.

Falcons (rugby team)

The Falcons – better known by their Afrikaans name the Valke and currently known as the Hino Valke for sponsorship reasons – are a South African rugby union team in Gauteng province that participates in the annual Currie Cup and Vodacom Cup tournaments.

Their home ground is currently Barnard Stadium in Kempton Park, to which they have returned in 2009. The Falcons have operated out of both Bosman Stadium in Brakpan and Pam Brink Stadium in Springs. They occasionally still host matches at Bosman Stadium. The Falcons draw players from Ekurhuleni and other municipalities to the east and south of Johannesburg.

History

The Falcons Rugby Union was originally founded in 1947, and was previously known as the Eastern Transvaal Rugby Football Union. After the 1995 World Cup, rugby was declared a professional sport in South Africa, after which the Eastern Transvaal Rugby Football Union merged with the Vaal Triangle Rugby Union to form the Gauteng Falcons Rugby Union and are one of only fourteen Provincial Unions in the country.

Favorites (Crystal Gayle album)

Favorites is a compilation album by the American country music singer Crystal Gayle. It was released in 1980, only a short time after another compilation album, Classic Crystal, though consisted of her lesser known songs from the period she was signed to United Artists Records.

The album peaked at #37 on the Billboard Country Albums chart, and #149 on the main Billboard 200 chart.
