Zij Al-Sindhind
''Zīj as-Sindhind'' (, ''Zīj as‐Sindhind al‐kabīr'', lit. "Great astronomical tables of the Sindhind"; from Sanskrit ''siddhānta'', "system" or "treatise") is a work of zij (astronomical handbook with tables used to calculate celestial positions) brought in the early 770s AD to the court of Caliph al-Mansur in Baghdad from India. Al-Mansur requested an Arabic translation of this work from the Sanskrit. The 8th-century astronomer and translator Muhammad al-Fazari is known to have contributed to this translation. In his book ''Ṭabaqāt al-ʼUmam (Categories of Nations)'', Said al-Andalusi informs that others who worked on it include al-Baghdadi and al-Khwarizmi. He adds that its meaning is "ad-dahr ad-dahir" (infinite time or cyclic time). Content This is the first of many Arabic zijs based on the Indian astronomical methods known as the Sindhind. The work contains tables for the movements of the sun, the moon and the five planets known at the time. It consists of ap ...

Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Kalpa (aeon)
A ''kalpa'' is a long period of time (aeon) in Hindu and Buddhist cosmology, generally between the creation and recreation of a world or universe. Etymology ''Kalpa'' ( sa, कल्प, , a formation or creation) in this context, means "a long period of time (aeon) related to the lifetime of the universe (creation)." It is derived from ''कॢप्'' (kḷp) + -अ (-a, nominalizing suffix) ( sa, कॢप्, kḷp, to create, prepare, form, produce, compose, invent). Hinduism In Hinduism, a ''kalpa'' is equal to 4.32 billion years, a "day of Brahma" (12-hour day proper) or one thousand '' mahayugas'', measuring the duration of the world. Each ''kalpa'' is divided into 14 ''manvantara'' periods, each lasting 71 ''Yuga Cycles'' (306,720,000 years). Preceding the first and following each ''manvantara'' period is a juncture (''sandhya'') equal to the length of a ''Satya Yuga'' (1,728,000 years). A ''kalpa'' is followed by a '' pralaya'' (dissolution) of equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical Works Of The Medieval Islamic World
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professio ...

History Of Astronomy
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. It was not completely separated in Europe (see astrology and astronomy) during the Copernican Revolution starting in 1543. In some cultures, astronomical data was used for astrological prognostication. Early history Early cultures identified celestial objects with gods and spirits. They related these objects (and their movements) to phenomena such as rain, drought, seasons, and tides. It is generally believed that the first astronomers were priests, and that they understood celestial objects and events to be manifestations of the divine, hence early astronomy's connection to what is now called astrology.
