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 diffe ...

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 ti ... [...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 Indus River, Sindhu (Indus) River. By the 16th century CE, the term began to refer to residents of the subcontinent who were not Turkic peoples, Turkic or Muslims. Hindoo is an archaic spelling variant, whose use today is considered derogatory. The historical development of Hindu self-i ...

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.) rathe ...

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 oce ...

Cylindrical
A cylinder (from ) has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology. The shift in the basic meaning—solid versus surface (as in ball and sphere)—has created some ambiguity with terminology. The two concepts may be distinguished by referring to solid cylinders and cylindrical surfaces. In the literature the unadorned term cylinder could refer to either of these or to an even more specialized object, the ''right circular cylinder''. Types The definitions and results in this section are taken from the 1913 text ''Plane and Solid Geometry'' by George Wentworth and David Eugene Smith . A ' is a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a fixed plane curve ...
