Short biography of Lobachevsky

Lobachevsky spent almost all his life in Kazan. There he studied at the gymnasium, then at Kazan University. He discovered outstanding abilities early and was left with him at the end of the university. In the year he became an ordinary professor, and five years later, Lobachevsky was elected rector of Kazan University, and over 19 years of leadership he achieved his true heyday. Lobachevsky was looking for ways of strict construction of the beginning of geometry.

The records of his lectures were preserved, where they made an attempt to prove the postulate of the parallelism of Euclid, but in the manuscript of the textbook “Geometry” he already abandoned this attempt.

Finally, having overcome the thousand -year traditions of ideas about geometry, he comes to the creation of new geometry. In the year, he presented the work “a compressed presentation began geometry with strict proof of the theorem about the parallel”, in which the “imaginary geometry” opened by him was described, as he called his system. The composition was included in Lobachevsky in his work “On the Principles of Geometry”, which was the first publication in non -Euclidean geometry in world literature.

The system developed by Lobachevsky is significantly different from Euclidean geometry. In accordance with his materialistic approach to the study of nature, Lobachevsky believed that only scientific experience could identify which geometry works in the physical space. Using the latest astronomical data of that time, he substantiated the practical suitability of Euclidean geometry and showed how Nonevlidov can be used in other sections of mathematics, namely in mathematical analysis when calculating certain integrals.

He praised the studies of the Lobachevsky Gauss, which is due to the fact that he was engaged in the theory of parallelity of lines since the 19ths of the 18th century, he came to the same conclusions as Lobachevsky. Gauss did not publish his views on this issue, they were preserved only in his draft notes and in few letters to friends. It is curious that, regardless of Lobachevsky and Gauss, the Hungarian mathematician Yanosh Boyya came to the discovery of non -Euclidery geometry, but Gauss, to whom Boyya sent a brief presentation of his discovery, did not contribute to the recognition of his discovery.

In the year, Lobachevsky issued his last work in Kazan in Russian and French - “Pangeometry”. He wrote it a year before his death, dictating her text. Nikolai Ivanovich Lobachevsky died on February 12 24 in Kazan. Wide recognition came to the summer anniversary of Lobachevsky - an international prize was established, a monument was erected in Kazan. Persons of the day of March 17:-Alexey Brusilov Russian and Soviet military leader, Adjutant General, Military teacher.
