Nandigrama
Nandigrama is the name of a location, place or region somewhere in Western India where a school of astronomers and mathematicians flourished during the thirteenth-eighteenth centuries CE. David Pingree, one of America's leading historians of the exact sciences (primarily mathematics) in antiquity, identified Nandigrama with Nandod in Gujarat. However, modern scholarship has identified Nandigrama as the Nandgaon village in the Raigad district in Maharashtra State. It lies about 64 km south of Mumbai on the Konkan coast. Astronomers and mathematicians Ganesa Daivajna was an astronomer born in 1507 in Nandigrama. His father Kesava Daivajna and paternal grandfather Kamalakara (not to be confused with Kamalakara of Golagrama) were also eminent astronomers. Kesava has been considered as one of the best observational astronomers of ancient India. Ganesa authored several important treatises and manuals on astronomy and astrology. Some of them are "Grahalaghava," "Laghu- and B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaṇeśa Daivajna
Gaṇeśa Daivajna (born 1507, 1520-1554) was a sixteenth century astronomer, astrologer, and mathematician from western India who wrote books on methods to predict eclipses, planetary conjunctions, positions, and make calculations for calendars. His most major work was the ''Grahalaghava'' which was included ephemeris and calendar calculations. Ganesa was born in Nandigrama (see also Golagrama) where his father Kesava (fl. 1496-1507) was a Brahmin Brahmin (; sa, ब्राह्मण, brāhmaṇa) is a varna as well as a caste within Hindu society. The Brahmins are designated as the priestly class as they serve as priests (purohit, pandit, or pujari) and religious teachers (gur ... astronomer. His mother's name has been noted as Lakshmi and he spent his entire life at Nandigrama. The location of Nandigrama has been suggested by some as being in Gujarat but more careful study of his work places it in Nandgaon in present day Maharashtra. He wrote several works i ...

Golagrama
Golagrama is a village or region in India associated with several medieval Indian astronomers, astrologers and mathematicians. Presently there is no place bearing the name Golagrama anywhere in India. It is known that Golagrama was situated in Maharashtra State on the northern banks of river Godavari, was near Partha-puri (Pathari) in Maharashtra and was about 320 km away from Amravati town in Maharashtra. It is sometimes identified as a place named ''Golgam'' at latitude 18° N longitude 78° E. The name ''Golagrama'' considered as a word in Sanskrit could literally be translated as ''sphere-village''. Golagrama school of astronomy Several medieval Indian astronomers and mathematicians are known to have flourished in Golagrama. They were all members of one large extended family. The astronomical and mathematical knowledge of the members of this family was passed from generation to generation through teacher-pupil relationships. In nearly all the cases, the teacher would be an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dadhigrama
Dadhigrama was a village on the banks of Payosni river in Vidarbha where a school of mathematics and astronomy flourished during the 14th to 19th centuries CE.

Kamalakara
Kamalakara (1616 – 1700) was an Indian astronomer and mathematician, came from a learned family of scholars from Golagrāma, a village situated in Maharashtra State near Partha-puri (Pathari) on the northern bank of the river Godāvarī. His father was Nrsimha who was born in 1586. Two of Kamalakara's three brothers were also astronomer and mathematicians: Divakara, who was the eldest of the brothers born in 1606, and Ranganatha who was youngest. Kamalākara learnt astronomy from his elder brother Divākara, who compiled five works on astronomy. His family later moved to Vārāṇasī. Major works Kamalākara's major work, "Siddhāntatattvaviveka", was compiled in Varanasi at about 1658 and has been published by Sudhakar Dwivedi in the Vārāṇasī series. This work consists of 13 chapters in 3,024 verses. It deals with the topics of: units of time measurement; mean motions of the planets; true longitudes of the planets; the three problems of diurnal rotation; diameters and d ...

Newnes
Newnes (), an abandoned oil shale mining site of the Wolgan Valley, is located in the Central Tablelands region of New South Wales, Australia. The site that was operational in the early 20th century is now partly surrounded by Wollemi National Park. The settlement was originally built by the Commonwealth Oil Corporation. History and description A major oil shale mine with two headings was started on the north side of the Wolgan River, opposite the works. It was intended to tunnel through the mountain to meet up with some earlier workings in the Capertee Valley as mining conditions in the Capertee were regarded as being much better than in the Wolgan. However, mining difficulties and the generally low quality of the shale in this area meant that mining became concentrated on the No. 2 mine and work on the No. 1 mine was eventually abandoned. Although construction of a tunnel linking the Wolgan Valley with the Capertee was proposed on numerous subsequent occasions, it was to ...

West India
Western India is a loosely defined region of India consisting of its western part. The Ministry of Home Affairs in its Western Zonal Council Administrative division includes the states of Goa, Gujarat, and Maharashtra along with the Union territory of Dadra and Nagar Haveli and Daman and Diu, while the Ministry of Culture and some historians also include the state of Rajasthan.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Maharashtra State
Maharashtra (; , abbr. MH or Maha) is a state in the western peninsular region of India occupying a substantial portion of the Deccan Plateau. Maharashtra is the second-most populous state in India and the second-most populous country subdivision globally. It was formed on 1 May 1960 by splitting the bilingual Bombay State, which had existed since 1956, into majority Marathi-speaking Maharashtra and Gujarati-speaking Gujarat. Maharashtra is home to the Marathi people, the predominant ethno-linguistic group, who speak the Marathi language, the official language of the state. The state is divided into 6 divisions and 36 districts, with the state capital being Mumbai, the most populous urban area in India, and Nagpur serving as the winter capital, which also hosts the winter session of the state legislature. Godavari and Krishna are the two major rivers in the state. Forests cover 16.47 per cent of the state's geographical area. Out of the total cultivable land in the state, ...
