Who is supposed curvature of space?

Who is supposed curvature of space? In Nizhny Novgorod, a boy, was transferred to Kazan, later became 1,111,112. student [/url] Kazan University, then worked in it. That's all I cling to nothing of his biography. He later became rector, but I did not. Rector of Kazan University is now a classmate of mine Misha Salakhov.

And the boy, born Dec. 1, 1792, and is now known to all. His name was Nikolai Ivanovich Lobachevsky. Everyone knows that he discovered non-Euclidean geometry, but few understand what it is. As everyone has heard about Albert Einstein's theory of relativity, but do not understand this. But their theories are closely related.

What opened Nikolai Lobachevsky?

By definition, the Euclidean parallel lines - straight lines lying in one plane and never intersect, how far we have not kept them. Prove or disprove this postulate have been trying to Euclid's contemporaries, and so it continued for two millennia. And in the first quarter of the XIX century the problem taken by many mathematicians. Lobachevsky first proposed that the space can be curved, and has developed a geometry for it.

For the first time his genius for speculation Nikolai publicly announced the university on Feb. 23, 1826 in the report "Imaginary Geometry". Lobachevsky gave his report as "virtually" because of the fact that in the real world what he said was impossible to observe. Curiously, a year later, another Russian genius Alexander Pushkin, who, as we know, hated math, dropped a remarkable phrase: "Inspiration is needed in geometry, as in poetry." It is unlikely that the capital works of the poet reading a provincial scholar and knew him personally (though historians admit the possibility of their meeting in Kazan house Fuchs), but it is clear that without inspiration create something that did Lobachevsky, it is simply impossible.

 In 1835 the scientist published a fundamental book called "imaginary geometry". Then develops his ideas in "new lines of geometry with the complete theory of parallel, in the foreword which says:" In vain effort since the days of Euclid, for two thousand years, made me suspect that in the definition is not the truth, which would prove and verify that, like other physical laws, can only experience what, for example, astronomical observations. And 15 years later, Bernard Riemann created geometry for multidimensional spaces, where parallel lines can be closed.

Already in the twentieth century, Albert Einstein substantiate these conjectures. Taking into the work of Lobachevsky and Riemann, he created the theory of relativity, which confirmed the curvature of our space.

According to the theory of relativity, any material mass bends space around it. It has been repeatedly confirmed by astronomical observations, and it became clear that the geometry of Lobachevskii describes the real universe that surrounds us.
