Cadiz vs Lux

Informations

Cádiz (, also US: , Spanish: [ˈkaðiθ]; see more below) is a city and port in southwestern Spain. It is the capital of the Province of Cádiz, one of eight which make up the autonomous community of Andalusia. Cádiz, one of the oldest continuously inhabited cities in Western Europe, with archaeological remains dating to 3100 years, was founded by the Phoenicians. It has been a principal home port of the Spanish Navy since the accession of the Spanish Bourbons in the 18th century. The city is a member of the Most Ancient European Towns Network. It is also the site of the University of Cádiz. Situated on a narrow slice of land surrounded by the sea‚ Cádiz is, in most respects, a typically Andalusian city with a wealth of attractive vistas and well-preserved historical landmarks.

The older part of Cádiz within the remnants of the city walls is commonly referred to as the Old Town (Spanish: Casco Antiguo). It is characterized by the antiquity of its various quarters (barrios), among them El Pópulo, La Viña, and Santa María, which present a marked contrast to the newer areas of town. While the Old City's street plan consists of narrow winding alleys connecting large plazas, newer areas of Cádiz typically have wide avenues and more modern buildings. In addition, the city is dotted with numerous parks where exotic plants flourish, including giant trees supposedly brought to Spain by Columbus from the New World.

The lux (symbol: lx) is the SI derived unit of illuminance, 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 watt 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 as both the singular and plural form.The word is derived from the Latin word for "light", lux.
