The middle day of the days counted, so one week of news cannot move it. The line under it is the last 390 days, one point a day.
Something wrong?He broke the 2,000-year grip of Euclidean certainty. Lobachevsky proved that parallel lines could behave otherwise - that geometry itself had more than one internally consistent form - and in doing so cracked open the conceptual door to relativity and modern physics.

There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.

About this person
Nikolai Ivanovich Lobachevsky was born in Russia on 1 December 1792 and spent his career as a mathematician and geometer working on problems that most of his contemporaries considered solved. His central achievement was hyperbolic geometry, a coherent system in which Euclid's parallel postulate does not hold - a notion so alien that it took decades for the mathematical community to accept it as legitimate rather than heretical. He also produced fundamental work on Dirichlet integrals, formalized in what became known as the Lobachevsky integral formula. William Kingdon Clifford later named him the "Copernicus of Geometry" for overturning an ancient orthodoxy. He died on 24 February 1856, his revolution still unfolding.
