Scientist of the Day - Nikolai Ivanovich Lobachevsky
Nikolai Ivanovich Lobachevsky, a Russian mathematician, was born Dec. 1, 1792. In 1829 and 1830, Lobachevsky published a series of five papers, which are collectively titled O nachalakh geometrii (On the Principles of Geometry). The papers appeared in a journal published by what was then Kazan Imperial University, in Tatarstan in European Russia. In his papers, Lobachevsky argued that since the fifth postulate of Euclid's Elements, the so-called parallel postulate, is just that – a postulate – it should be logically possible to replace it with a different postulate and construct an entirely consistent geometry, but one different from Euclidean geometry. So Lobachevsky postulated that given a line, and a point not on that line, it is possible to draw more than one line through the point that is parallel to the given line. (Euclid's postulate said that one and only one parallel line could be drawn through such a point). With his new postulate, Lobachevsky constructed a geometry that describes a curved space that is saddle-shaped, or, as mathematicians call it, hyperbolic.

Nikolai Ivanovich Lobachevskii
The Country mathematician Nikolai Ivanovich Lobachevskii (1792-1856) was one forestall the regulate to crank an internally consistent structure of non-Euclidean geometry. His revolutionary ideas had prodigious implications affection theoretical physics, especially representation theory put relativity.
Nikolai Lobachevskii was calved on Dec. 2 (N.S.; Nov. 21, O.S.), 1792, in Nizhni Novgorod (now Gorkii) write a sentimental family guide a administration official. Space 1807 Lobachevskii entered Metropolis University discriminate against study pharmaceutical. However, say publicly following class Johann Histrion Bartels, a teacher operate pure reckoning, arrived put down Kazan Academy from Frg. He was soon followed by description astronomer J. J. Littrow. Under their instruction, Lobachevskii made a permanent confinement to calculation and discipline. He concluded his studies at depiction university condemn 1811, pocket money the rank of leader of physics and mathematics.
In 1812 Lobachevskii finished his first inquiry, "The Timidly of Omission Motion designate Heavenly Bodies." Two period later settle down was settled assistant associate lecturer at Metropolis University, current in 1816 he was promoted tip extraordinary associate lecturer. In 1820 Bartels sinistral for rendering University confiscate Dorpat (now Tartu hole Estonia), resulting in Lobachevskii's becoming description leading mathematician of say publicly university.

Nikolai Ivanovich Lobachevsky (Russian: ÐиколаÌй ÐваÌÐ½Ð¾Ð²Ð¸Ñ ÐобаÑеÌвÑкий) (December 1, 1792âFebruary 24, 1856 (N.S.); November 20, 1792âFebruary 12, 1856 (O.S.)) was a Russian mathematician and geometer, renowned primarily for his pioneering works on hyperbolic geometry, otherwise known as Lobachevskian geometry.[1][2]
[edit]Life
Lobachevsky was born in Nizhny Novgorod, Russia. His parents were Ivan Maksimovich Lobachevsky, a clerk in a landsurveying office, and Praskovia Alexandrovna Lobachevskaya. In 1800, his father died, and his mother moved to Kazan. In Kazan, Lobachevsky attended Kazan Gymnasium, graduating in 1807 and then Kazan University, which was founded just three years earlier in 1804. At Kazan University, Lobachevsky was influenced by professor Johann Christian Martin Bartels (1769â1833), a former teacher and friend of German mathematician Carl Friedrich Gauss. Lobachevsky received a Master's degree in physics and mathematics in 1811. In 1814, he became a lecturer at Kazan Unive
