Nikolai Ivanovich Lobachevsky

Nikolai Ivanovich Lobachevsky (1792-1856) was a Russian mathematician best known for developing non-Euclidean geometry, a revolutionary shift in how we understand space and shapes. Traditional geometry, based on Euclid’s postulates, assumes parallel lines never meet. Lobachevsky proposed a system where this is not true, allowing for multiple parallel lines through a point. His work challenged long-held beliefs and laid the groundwork for modern geometry and theoretical physics, influencing later concepts in fields like relativity. Lobachevsky’s ideas showed that mathematics could encompass a broader range of possibilities, reshaping our understanding of the universe.
