Misra Yantra
Mishra Yantra is one of the four unique astronomical instruments of the Jantar Mantar observatory located in New Delhi, India. Each instrument at the Jantar Mantar are separate brilliant architectures constructed based on mathematical observations, and help in calculating different aspects of celestial objects and time. It is widely believed that the Jantar Mantar was constructed in the year 1724. The four instruments of Jantar Mantar are Samrat Yantra (a large sundial for calculating time), Jay Prakash Yantra (2 concave hemispherical structures, used to ascertain the position of Sun and other heavenly bodies), Ram Yantra (two large cylindrical structures with open top, used to measure the altitude of stars based on the latitude and the longitude on the earth) and the Mishra Yantra (meaning ''mixed instrument'', since it is a compilation of five different instruments). Historical and cultural importance of the Mishra Yantra The Mishra or composite Yantra is composed of five dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jantar Mantar, New Delhi (Misra Yantra)
Jantar Mantar is located in the modern city of New Delhi. “Jantar Mantar” it means “instruments for measuring the harmony of the heavens”. It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 onwards, revising the calendar and astronomical tables. Jai Singh, born in 1688 into a royal Rajput family that ruled the regional kingdom, was born into an era of education that maintained a keen interest in astronomy. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710. Later research, though, suggests 1724 as the actual year of construction. Its height is . The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets. Some of these purposes nowadays would be classified as astronomy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east– west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hindu
Hindus (; ) are people who religiously adhere to Hinduism. Jeffery D. Long (2007), A Vision for Hinduism, IB Tauris, , pages 35–37 Historically, the term has also been used as a geographical, cultural, and later religious identifier for people living in the Indian subcontinent. The term ''"Hindu"'' traces back to Old Persian which derived these names from the Sanskrit name ''Sindhu'' (सिन्धु ), referring to the river Indus. The Greek cognates of the same terms are "''Indus''" (for the river) and "''India''" (for the land of the river). The term "''Hindu''" also implied a geographic, ethnic or cultural identifier for people living in the Indian subcontinent around or beyond the Sindhu (Indus) River. By the 16th century CE, the term began to refer to residents of the subcontinent who were not Turkic or Muslims. Hindoo is an archaic spelling variant, whose use today is considered derogatory. The historical development of Hindu self-identity within the local ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab (etymology)
The proper name ''Arab'' or ''Arabian'' (and cognates in other languages) has been used to translate several different but similar-sounding words in ancient and classical texts which do not necessarily have the same meaning or origin. The etymology of the term is closely linked to that of the place name ''Arabia''. Semitic etymology The root of the word has many meanings in Semitic languages including ''desert'', ''nomad'', ''merchant'', ''raven'' and ''comprehensible'' with all of these having varying degrees of relevance to the emergence of the name. It is also possible that some forms were metathetical from root "moving around", and hence, it is alleged, "nomadic." The plurality of meanings results partly from the assimilation of the proto-Semitic '' ghayin'' with in some languages. In Hebrew the word ' thus has the same triconsonantal root as the root meaning "west" ( ') "setting sun" or "evening" ( ', '). The direct Arabic cognate of this is ' ("west", etc.) rather ...

Greeks
The Greeks or Hellenes (; el, Έλληνες, ''Éllines'' ) are an ethnic group and nation indigenous to the Eastern Mediterranean and the Black Sea regions, namely Greece, Cyprus, Albania, Italy, Turkey, Egypt, and, to a lesser extent, other countries surrounding the Mediterranean Sea. They also form a significant diaspora (), with Greek communities established around the world.. Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people themselves have always been centered on the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age.. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocea ...
