Radhanath Sikdar
Radhanath Sikdar (Bengali: রাধানাথ শিকদার; 5 October 1813 – 17 May 1870) was an Indian mathematician who is best known for calculating the height of Mount Everest. He was the first person to calculate the height of Mount Everest, in 1852. Great Trigonometric Survey In 1831, George Everest, the Surveyor General of India, was in the pursuit of a mathematician who had specialised in Spherical Trigonometry, so that they could be a part of the Great Trigonometric Survey. In 1832, under the leadership of Everest, the longitudinal series of the "triangle" survey was completed from Seronj in Madhya Pradesh to Calcutta in West Bengal. While still working on mapping Calcutta, Bengal, Everest had begun his search for a mathematician, and soon enough, John Tytler, a professor of Mathematics at the Hindu College, now known as the Presidency College, recommended his 19-year-old pupil, Radhanath Sikdar. Radhanath, a student of the college since 1824, was one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jorasanko
Jorasanko is a neighbourhood of North Kolkata, in Kolkata district, West Bengal, India. It is so called because of the two (''jora'') wooden or bamboo bridges (''sanko'') that spanned a small stream at this point.

Peary Chand Mitra
Peary Chand Mitra (22 July 1814 – 23 November 1883) was an Indian writer, journalist, cultural activist and entrepreneur. His pseudonym was Tek Chand Thakur. He was a member of Henry Derozio's Young Bengal group, who played a leading role in the Bengal renaissance with the introduction of simple Bengali prose. His ''Alaler Gharer Dulal'' pioneered the novel in the Bengali language, leading to a tradition taken up by Bankim Chandra Chatterjee and others. Mitra died on 23 November 1883 in Kolkata.

Young Bengal
The Young Bengal was a group of Bengali free thinkers emerging from Hindu College, Calcutta. They were also known as Derozians, after their firebrand teacher at Hindu College, Henry Louis Vivian Derozio. The Young Bengal Movement peripherally included Christians such as Reverend Alexander Duff (1809–1878), who founded the General Assembly's Institution, and his students like Lal Behari Dey (1824–1892), who went on to renounce Hinduism. Latter-day inheritors of the legacy of the Young Bengal Movement include scholars like Brajendra Nath Seal (1864–1938), who went on to be one of the leading theologians and thinkers of the Brahmo Samaj. The Derozians however failed to have a long term impact. Derozio was removed from the Hindu college in 1831 because of radicalism. The main reason for their limited success was social conditions prevailing at that time which were not ripe for adoption of radical ideas. Further, they did not link masses through peasant causes.

Kangchenjunga
Kangchenjunga, also spelled Kanchenjunga, Kanchanjanghā (), and Khangchendzonga, is the third highest mountain in the world. Its summit lies at in a section of the Himalayas, the ''Kangchenjunga Himal'', which is bounded in the west by the Tamur River, in the north by the Lhonak River and Jongsang La, and in the east by the Teesta River. It lies in the border region between Nepal and Sikkim state of India, with three of the five peaks, namely Main, Central and South, directly on the border, and the peaks West and Kangbachen in Nepal's Taplejung District. Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations and measurements by the Great Trigonometrical Survey of India in 1849 showed that Mount Everest, known as Peak XV at the time, is actually higher. After allowing for further verification of all calculations, it was officially announced in 1856 that Kangchenjunga was the third highest mountain. The Kangchenjunga is a sacred mount ...

Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, 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 Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

Analytic Geometry
In classical mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry. Analytic geometry is used in physics and engineering, and also in aviation, Aerospace engineering, rocketry, space science, and spaceflight. It is the foundation of most modern fields of geometry, including Algebraic geometry, algebraic, Differential geometry, differential, Discrete geometry, discrete and computational geometry. Usually the Cartesian coordinate system is applied to manipulate equations for planes, straight lines, and circles, often in two and sometimes three dimensions. Geometrically, one studies the Euclidean plane (two dimensions) and Euclidean space. As taught in school books, analytic geometry can be explained more simply: it is concerned with defining and representing geometric shapes in a numerical way and extracting numerical information from shapes' numerical defin ...

Euclid's Elements
The ''Elements'' ( grc, Στοιχεῖα ''Stoikheîa'') is a mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt 300 BC. It is a collection of definitions, postulates, propositions (theorems and constructions), and mathematical proofs of the propositions. The books cover plane and solid Euclidean geometry, elementary number theory, and incommensurable lines. ''Elements'' is the oldest extant large-scale deductive treatment of mathematics. It has proven instrumental in the development of logic and modern science, and its logical rigor was not surpassed until the 19th century. Euclid's ''Elements'' has been referred to as the most successful and influential textbook ever written. It was one of the very earliest mathematical works to be printed after the invention of the printing press and has been estimated to be second only to the Bible in the number of editions published since the first printing i ...
