Baghdad vs Lux

Informations

Baghdad (; Arabic: بَغْدَاد‎ [baɣˈdaːd] (listen)) is the capital of Iraq and one of the largest cities in the Arab world. Located along the Tigris, near the ruins of the Akkadian city of Babylon and the ancient Iranian capital of Ctesiphon, Baghdad was founded in the 8th century and became the capital of the Abbasid Caliphate. Within a short time, Baghdad evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as hosting a multiethnic and multireligious environment, garnered the city a worldwide reputation as the "Centre of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many centuries due to frequent plagues and multiple successive empires.

With the recognition of Iraq as an independent state (formerly the British Mandate of Mesopotamia) in 1932, Baghdad gradually regained some of its former prominence as a significant center of Arabic culture, with a population variously estimated at 6 or over 7 million.In contemporary times, the city has often faced severe infrastructural damage, most recently due to the United States-led 2003 invasion of Iraq, and the subsequent Iraq War that lasted until December 2011. In recent years, the city has been frequently subjected to insurgent attacks, resulting in a substantial loss of cultural heritage and historical artifacts as well. As of 2018, Baghdad was listed as one of the least hospitable places to live, ranked by Mercer as the world's worst major city for quality of life.

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.
