Lux vs Macau

Informations

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.

Informations

Macau ( (listen); 澳門, Cantonese: [ōu.mǔːn]; Portuguese: [mɐˈkaw]), also spelled Macao and officially the Macao Special Administrative Region of the People's Republic of China, is a city and special administrative region of the People's Republic of China in the western Pearl River Delta by the South China Sea. With a population of about 680,000 and an area of 32.9 km2 (12.7 sq mi), it is the most densely populated region in the world. Macau is a former colony of the Portuguese Empire, after Ming China leased the territory as a trading post in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887, when it gained perpetual colonial rights in the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until 1999, when it was transferred to China. Macau is a special administrative region of China, which maintains separate governing and economic systems from those of mainland China under the principle of "one country, two systems".

Originally a sparsely populated collection of coastal islands, the territory has become a major resort city and a top destination for gambling tourism, with a gambling industry seven times larger than that of Las Vegas. The city has one of the highest per capita incomes in the world, and its GDP per capita by purchasing power parity is one of the highest in the world; however, income inequality remains high. It has a very high Human Development Index, as calculated by the Macau government, and the fourth-highest life expectancy in the world. The territory is highly urbanised and most development is built on reclaimed land; two-thirds of the total land area is reclaimed from the sea.
