Nicolai Lobachevsky was a Russian mathematician best known for developing non-Euclidean geometry, which challenged the long-standing assumptions of Euclidean geometry. He introduced the concept of hyperbolic geometry, where the parallel postulate of Euclidean geometry does not hold, leading to a new understanding of space and shape. His work laid the foundation for modern geometry and had profound implications in various fields, including physics and cosmology. Lobachevsky's contributions were pivotal in shaping the mathematical landscape of the 19th century.
