Suryadeva Yajvan
Suryadeva (1191 – at least 1248 CE) was a Sanskrit-language writer on astrology and astronomy (''jyotisha'')) from the Chola kingdom of southern India. He wrote commentaries on several notable works including the ''Aryabhatiya'' and the '' Laghu-manasa''. Biography Suryadeva was a Brahmana of the Nidhruva ''gotra'', associated with the '' Bodhayana Sutra'', claiming descent ( pravaras) from the sages Kashyapa, Avatsara, and Naidhruva. His works use different suffixes for his name, including Sūri, Yajvā, Yajvān, Somasut, and Dīkṣita. Sūri refers to his scholarship; the other suffixes suggest that he had performed the Soma-yajna ritual sacrifice. According to his commentary on ''Laghumanasa'', Suryadeva was born in 1191 CE (Monday, 3rd day of the dark half of the Magha month of the Shaka year 1113). He lived in the Chola kingdom, and resided in a town that different manuscripts variously call Gangapuram, Gangapuri, and Shri-ranga-gangapuri; this town can be identified ...

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 ...

Magha (month)
Maagha (Hindi: माघ ''maagh'') is a month of the Hindu calendar. In India's national civil calendar, it's the eleventh month of the year, corresponding to January/February in the Gregorian calendar.Henderson, Helene. (Ed.) (2005) ''Holidays, festivals, and celebrations of the world dictionary'' Third edition. Electronic edition. Detroit: Omnigraphics, p. xxix. In lunar calendars, Maagh may begin on either the new moon or the full moon around the same time of year, and is usually the tenth month of the year. It is named thus because, in this month, the full moon is usually found nearby or within the star cluster called "Magha". In solar calendars, Maagh begins with the Sun's entry into Capricorn, and is usually the eleventh month of the year. Festivals * Shukla Panchami: Vasant Panchami * Shukla Saptami: Ratha Saptami * Maagh Mela is an important festival celebrated most of North India. * The world-famous "Maha Maham" festival which is held every 12 years during full ...

13th-century Indian Astronomers
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo resisted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
12th-century Indian Astronomers
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parameshvara Nambudiri
Vatasseri Parameshvara Nambudiri ( 1380–1460) was a major Indian mathematician and astronomer of the Kerala school of astronomy and mathematics founded by Madhava of Sangamagrama. He was also an astrologer. Parameshvara was a proponent of observational astronomy in medieval India and he himself had made a series of eclipse observations to verify the accuracy of the computational methods then in use. Based on his eclipse observations, Parameshvara proposed several corrections to the astronomical parameters which had been in use since the times of Aryabhata. The computational scheme based on the revised set of parameters has come to be known as the ''Drgganita'' or Drig system. Parameshvara was also a prolific writer on matters relating to astronomy. At least 25 manuscripts have been identified as being authored by Parameshvara. Biographical details Parameshvara was a Hindu of Bhrgugotra following the Ashvalayanasutra of the Rigveda.

Bhāskara I
Bhāskara () (commonly called Bhāskara I to avoid confusion with the 12th-century mathematician Bhāskara II) was a 7th-century Indian mathematician and astronomer who was the first to write numbers in the Hindu–Arabic decimal system with a circle for the zero, and who gave a unique and remarkable rational approximation of the sine function in his commentary on Aryabhata's work. This commentary, ''Āryabhaṭīyabhāṣya'', written in 629 CE, is among the oldest known prose works in Sanskrit on mathematics and astronomy. He also wrote two astronomical works in the line of Aryabhata's school: the ''Mahābhāskarīya'' (“Great Book of Bhaskara”) and the ''Laghubhāskarīya'' (“Small Book of Bhaskara”). On 7 June 1979, the Indian Space Research Organisation launched the Bhāskara I satellite, named in honour of the mathematician. Biography Little is known about Bhāskara's life, except for what can be deduced from his writings. He was born in India in the 7th centu ...

Vrddha Garga
Garga, also known as Vṛddha Garga ("Garga the Elder"), was an ancient Indian scholar of jyotisha. Several Sanskrit-language jyotiḥśāstra works - covering topics such as astrology, astronomy, and divination - are attributed to him. These works were written over several centuries, and are obviously not the work of a single author. Modern scholars generally date the oldest of these works - ''Gargiya-jyotisha'' - to the 1st century CE, although the source materials for these works may be much older. Biography Garga is also called Vṛddha-Garga ("Garga the Elder") to distinguish him from his later namesakes. He is among the earliest and the most important authors in the jyotisha tradition.

Shaka Era
The Shaka era (IAST: Śaka, Śāka) is a historical Hindu calendar era (year numbering), the epoch (its year zero) of which corresponds to Julian year 78. The era has been widely used in different regions of India as well as in SE Asia. History There are two Shaka era systems in scholarly use, one is called ''Old Shaka Era'', whose epoch is uncertain, probably sometime in the 1st millennium BCE because ancient Buddhist and Jaina inscriptions and texts use it, but this is a subject of dispute among scholars. The other is called ''Saka Era of 78 CE'', or simply ''Saka Era'', a system that is common in epigraphic evidence from southern India. A parallel northern India system is the ''Vikrama Era'', which is used by the Vikrami calendar linked to Vikramaditya. The beginning of the Shaka era is now widely equated to the ascension of king Chashtana in 78 CE. His inscriptions, dated to the years 11 and 52, have been found at Andhau in Kutch region. These years are interpreted as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
