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] |
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. Cintāmani, a Brahmana of the Devaratragotra, in the middle of the 15th century, Rama (who was patronized by a king of Vidarbha), Trimalla, and Vallala, Munisvara a grandson of Vallala, his son Rama, who wrote a commentary on the Sudhārasasāranī of Ananta (fl. 1525), Ḳrshnạ (fl. 1600–1625) etc. were some of the well-known members of this school of mathematicians. Ranganatha (fl. 1603), another astronomer of the school, wrote Gūḍhārthaprakāśikā, a commentary on the Suryasidhanta.

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] |

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 ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Kerala School Of Astronomy And Mathematics
The Kerala school of astronomy and mathematics or the Kerala school was a school of Indian mathematics, mathematics and Indian astronomy, astronomy founded by Madhava of Sangamagrama in Kingdom of Tanur, Tirur, Malappuram district, Malappuram, Kerala, India, which included among its members: Parameshvara, Neelakanta Somayaji, Jyeshtadeva, Achyuta Pisharati, Melpathur Narayana Bhattathiri and Achyuta Panikkar. The school flourished between the 14th and 16th centuries and the original discoveries of the school seems to have ended with Melpathur Narayana Bhattathiri, Narayana Bhattathiri (1559–1632). In attempting to solve astronomical problems, the Kerala school independently discovered a number of important mathematical concepts. Their most important results—series expansion for trigonometric functions—were described in Sanskrit verse in a book by Neelakanta called ''Tantrasangraha'', and again in a commentary on this work, called ''Tantrasangraha-vakhya'', of unknown author ...
