Aqueduct (water supply)An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts.
Greater IranGreater Iran (ایران بزرگ Irān-e Bozorg), also known as Persosphere, refers to a sociocultural region in which Iranian traditions and Iranian languages have had a significant impact. It spans parts of West Asia, the Caucasus, Central Asia, South Asia, and Xinjiang. The region is defined by having been long-ruled by the dynasties of various Iranian empires, under whom the local populaces gradually incorporated some degree of Iranian influence into their cultural and/or linguistic traditions; or alternatively as where a considerable number of Iranian peoples settled to still maintain communities who patronize their respective cultures, geographically corresponding to the areas surrounding the Iranian plateau.
YazdYazd (یزد jæzd), formerly also known as Yezd, is the capital of Yazd province, Iran. The city is southeast of Isfahan. At the 2016 census, its population was 529,673. Since 2017, the historical city of Yazd is recognized as a World Heritage Site by UNESCO. Because of generations of adaptations to its desert surroundings, Yazd has a unique Persian architecture. It is nicknamed the "City of Windcatchers" (شهر بادگیرها Shahr-e Badgirha) from its many examples.
WindcatcherA windcatcher, wind tower, or wind scoop (ملقف, بادگیر) is a traditional architectural element used to create cross ventilation and passive cooling in buildings. Windcatchers come in various designs, depending on whether local prevailing winds are unidirectional, bidirectional, or multidirectional, on how they change with altitude, on the daily temperature cycle, on humidity, and on how much dust needs to be removed. Despite the name, windcatchers can also function without wind.
Islamic Golden AgeThe Islamic Golden Age was a period of scientific, economic and cultural flourishing in the history of Islam, traditionally dated from the 8th century to the 13th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom, which saw scholars from all over the Muslim world flock to Baghdad, the world's largest city by then, to translate the known world's classical knowledge into Arabic and Persian.
QazvinQazvin (kæzˈviːn; قزوین, ɢæzˈviːn, also Romanized as Qazvīn, Qazwin, Kazvin, Kasvin, Caspin, Casbin, Casbeen, or Ghazvin) is a city in the Central District of Qazvin County, Qazvin province, Iran, and serves as capital of the district, county, and province. It is the largest city in Qazvin province. Qazvin was a capital of the Safavid dynasty for over forty years (1555–1598) and nowadays is known as the calligraphy capital of Iran. It is famous for its traditional confectioneries (like Baghlava), carpet patterns, poets, political newspaper and Pahlavi influence on its accent.
Nazca cultureThe Nazca culture (also Nasca) was the archaeological culture that flourished from 100 BC to 800 AD beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. Strongly influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs.
Evaporative coolerAn evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling exploits the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization).
Water clockA water clock or clepsydra (; ; water thief) is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount is then measured. Water clocks are one of the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon, Egypt, and Persia around the 16th century BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain.
Culture of IranThe culture of Iran (فرهنگ ایران) or culture of Persia is among the most influential in the world. Iran (Persia) is widely considered to be one of the cradles of civilization. Due to its dominant geopolitical position in the world, it has heavily influenced peoples and cultures situated as far away as Southern Europe and Eastern Europe to the west; Central Asia to the north; the Arabian Peninsula to the south; and South Asia, East Asia, and Southeast Asia to the east.
