Comment
Date of issue: 01 DEC 1992Nikolai Ivanovich Lobachevsky (1792-1856), a Russian mathematician, is known as the creator of non-Euclidean geometry. From 1827 to 1846 he used to be the Chancellor of the Kazan University. Lobachevsky's discovery of 1826 (published in 1829-1830), ignored by his contemporaries, was a breakthrough in the understanding of the nature of space, which for more than 2000 years had been based on Euclid's assumptions, and had a tremendous impact on the development of mathematical thinking. Lobachevsky wrote works on algebra, mathematical analysis, the probability theory, mechanics, physics and astronomy.
Interesting fact
The interesting fact about this coin is that it features a portrait of Nikolai Ivanovich Lobachevsky, a renowned Russian mathematician who is best known for his work on hyperbolic geometry, which is a branch of non-Euclidean geometry that studies the properties of hyperbolic spaces.
