# Реферат: About Lobachevsky

Science is a very important and interesting field of activity ofman. Mathematics as a science is a good example of such activity.

Russian and Soviet mathematicians made a great contribution to thedevelopment of mathematics. World known are the name of S. Kovalevskaya, N.Lobachevsky and others. There are scientists who seem to be born scientists.And their life is not always a bed of roses, sometimes their life turns reallytragic. Lobachevsky's life is a good example and a proof of this statement.

Lobachevsky was born in 1792 near Nizhni Novgorod. When he was achild, his family moved to Kazan, where Lobachevsky entered the gymnasium. Hisprogress in mathematics was very rapid there.

At the age of 15 he entered the University of Kazan. At 19 he wasawarded a Master's degree. At the age of 24 Lobachevsky became a Professor ofmathematics at Kazan University. When he was 35, Lobachevsky was appointedrector of the University. Lobachevsky was 34 years old, when he foundednon-Euclidean geometry of two-dimensions. His geometry is valid forpseudosfherical surfaces. It is based on the assumption that the axiom onparallel to a given straight line.

It was one of the masterpieces of mathematics. Strange as it mayseem, scientists of old Russia and Europe did not support his geometry. ButLobachevsky was not discouraged. In 1846 he was dismissed from his office. Andstill Lobachevsky continued his research work, now at home. When he got blind,he dictated his new masterpiece-pan-geometry — to his pupils, Lobachevsky diedin 1856 at the age of 63.

So, we see that revolutionary idens in science, they struggletheir way through misunderstanding. And only a really talented and persistentpersonality can win.
