	Lobachevsky, Nikolai Ivanovich (1793-1856)
		Lobachevsky first announced his system in 1826 and subsequently wrote several expositions of it, including Geometrical Researches on the Theory of Parallels (originally published in 1840 in German).
		Lobachevsky studied and taught at the new University of Kazan and eventually became rector of this institution in 1826.
		However, for some reason, despite serving his country and university well, he fell from favor and in 1846 was relieved by the government of his posts as professor and rector.

		Nikolai Ivanovich Lobachevsky (December 1 1792 - February 24 1856) was a Russian mathematician.
		When Nikolai Ivanovich was seven years of age his father died and, in 1800, his mother moved with her three sons to the city of Kazan in western Russia on the edge of Siberia.
		Lobachevsky was also the subject of a particularily amusing song by Tom Lehrer in the 50s.

	Nikolai Ivanovich Lobachevsky - Wikipedia, the free encyclopedia
		At Kazan University, Lobachevsky was influenced by professor Johann Christian Martin Bartels (1769–1833), a former teacher and friend of Carl Friedrich Gauss.
		Another of Lobachevsky's achievements was developing a method for the approximation of the roots of algebraic equations.
		Lobachevsky gave the definition of a function as a correspondence between two sets of real numbers (Dirichlet gave the same definition independently soon after Lobachevsky).

	Lobachevsky biography
		When Nikolai Ivanovich was seven years of age his father died and, in 1800, his mother moved with her three sons to the city of Kazan in western Russia on the edge of Siberia.
		Lobachevsky was an impractical manager who jeopardised his financial position by purchasing the estate while living on a pension; that he had no time to look after the estate and took little interest in it; that he was left in poverty and ignored by the local officials, etc.
		The story of how Lobachevsky's hyperbolic geometry came to be accepted is a complex one and this biography is not the place in which to go into details, but we shall note the main events.

	Nikolai Ivanovich Lobachevsky Summary
		Lobachevsky was born on December 1, 1792, in Nizhny Novgorod (known as Gorky from 1932 to 1990), Russia.
		Lobachevsky's father died when he was about six or seven, depending on the source, and his mother took him and his two brothers, Alexander and Alexei, to Kazan where he spent the rest of his life.
		Lobachevsky then became the University librarian from 1825 to 1835, and was elected University Rector (equivalent to president) in 1827, a post he held until 1846.

		Lobachevsky was rector for almost 20 years, during which time the University went from strength to strength, both in its faculties and its student numbers.
		Lobachevsky’s work on geometry had really important implications for modern geometry - he along with Gauss can be said to be one of the discoverers of non-Euclidean geometry.

		Lobachevsky published the first account of the subject in 1829, but his work went unrecognized until Georg Riemann's system was published.
		Lobachevsky was born at Nizhni-Novgorod and studied at the University of Kazan, Tatarstan.

	Parallel - Part 3
		Lobachevski made an assumption about parallel lines that differed from Euclid's and proceeded to draw out its consequences.
		The formulas were what gave their work the precision needed to give conviction in the absence of a sound logical structure.
		Lobachevski observed that it had become an empirical matter to determine the nature of space, Lobachevsky even went so far as to conduct astronomical observations, although these proved inconclusive (Encyclopedia Britannica).

	Geometric structures: History and Development
		Investigations into the study of parallel lines led Janos Bolyai (1802-1860), Carl Friedrich Gauss (1777-1855) and Nikolai Invanovich Lobachevsky (1792-1856) to models of geometry in which either no parallel lines exist at all or infinitely many lines through a fixed point can miss a given line.
		Groups of symmetry were exploited in the early 19th century by Galois, and Jordan to prove that fifth-degree equations could not be solved by radicals, as in the quadratic formula.
		He imagined a space of arbitrary dimension, a "many-fold" space with a notion of length infinitesimally described by a quadratic function such as dx^2 + dy^2 + dz^2.
