Haridatta II
Haridatta II ( 1638) was an astronomer from Mewar (present day Rajasthan) who is known for creating one of the first astronomical tables in India, known as the ''Jagadbhūṣaṇa,'' published in 1638. Haridatta, the son of Haraji, lived during the reign of Jagatsiṃha I (1628–1652) of Mewar. Little is known about him other than from his published set of tables for identifying planetary positions by following the ''Brahmapaksha'' school of astronomy Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest includ .... It has been said that the earlier genre of algorithms coded in verse for the computation of planetary positions were replaced by the table-text format with this publication.

Mewar
Mewar, also spelled as Mewad is a region in the south-central part of Rajasthan state of India. It includes the present-day districts of Bhilwara, Chittorgarh, Pratapgarh, Rajsamand, Udaipur, Pirawa Tehsil of Jhalawar District of Rajasthan, Neemuch and Mandsaur of Madhya Pradesh and some parts of Gujarat. For centuries, the region was ruled by Rajputs as Kingdom of Mewar. During the period of British East India Company, it became a princely state as Udaipur. It emerged as an administrative unit during the period governance in India and remained until the end of the British Raj era. The Mewar region lies between the Aravali Range to the northwest, Ajmer to the north, Gujarat and the Vagad region of Rajasthan to the south, the Malwa region of Madhya Pradesh state to the south and the Hadoti region of Rajasthan to the east. Etymology The word "Mewar" is vernacular form of "Medapata" (IAST: Medapāṭa), the ancient name of the region. The earliest epigraph that ment ...

Ephemeris
In astronomy and celestial navigation, an ephemeris (; ; , ) is a book with tables that gives the trajectory of naturally occurring astronomical objects and artificial satellites in the sky, i.e., the position (and possibly velocity) over time. Historically, positions were given as printed tables of values, given at regular intervals of date and time. The calculation of these tables was one of the first applications of mechanical computers. Modern ephemerides are often provided in electronic form. However, printed ephemerides are still produced, as they are useful when computational devices are not available. The astronomical position calculated from an ephemeris is often given in the spherical polar coordinate system of right ascension and declination, together with the distance from the origin if applicable. Some of the astronomical phenomena of interest to astronomers are eclipses, apparent retrograde motion/planetary stations, planetary es, sidereal time, positions for ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east.

Jagat Singh I
Maharana Jagat Singh I (1607 – 10 April 1652), was a Sisodia Rajput ruler of Mewar Kingdom (r. 1628–1652). Biography Jagat Singh succeeded his father, Karan Singh II, as the ruler of Mewar. By the time he ascended the throne, the state had recovered enough from previous conflicts that he sought to expand Mewar’s influence over neighboring territories. During decades of warfare, Mewar had lost significant areas, and regions such as Mandalgarh, Banera, Shahpura, Dungarpur, and Banswara had become effectively autonomous, governed by local chiefs holding these lands as jagirs from the Mughal emperor. In an effort to reclaim lost territories, Jagat Singh launched military campaigns around 1635 against neighboring states including Pratapgarh-Deoliya, Dungarpur, Sirohi, and Banswara. During these conflicts, the ruler of Deoli, Jaswant Singh, was killed, leading his successor to appeal for Mughal intervention. Jagat Singh also began repairs on the fort of Chittor, an act t ...

Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, 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 atmosphere of Earth, 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 Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, M ...

American Philosophical Society
The American Philosophical Society (APS) is an American scholarly organization and learned society founded in 1743 in Philadelphia that promotes knowledge in the humanities and natural sciences through research, professional meetings, publications, source text, library resources, and community outreach. It was founded by the polymath Benjamin Franklin and is considered the first learned society founded in what became the United States.Philosophical Hall, the society's headquarters and a museum, is located just east of Independence Hall in Independence National Historical Park. In 1965, in recognition of the building's history, it was designated a National Historic Landmark. The society has about 1,000 elected members. As of April 2020, 5,710 members had been inducted since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanitie ...

17th-century Indian Astronomers
The 17th century lasted from January 1, 1601 (represented by the Roman numerals MDCI), to December 31, 1700 (MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded ro ...
