Albert Einstein (1879 - 1955).

A. Einstein - one of the outstanding thinkers of all the times. He completed the classical physics building started by Galilei and Newton and accomplished a revolution in the notions about space, time and gravitation. Einstein's "tool" was not an astronomic tube but theoretical mentality. The importance of his works may be compared only with the importance of Newton's works.

The most successful year for Einstein was 1905. He had written an article "To the electrodynamics of the moving solids", which may be considered as an introduction to the special theory of gravitation (STG), which revolved all ideas about the space and the time. The article "Does the solid's inertia depend on the energy in it?" completes the making of relative theory. There for the first time the connection between mass and energy was proved in the modern conventional sign - E=mc?. This discovery determines the human being's fortune up to the nowadays.

In 1916 Einstein published "The Basic General theory of relativity". Soon he understood that his theory should determine the whole structure of Universe. The first relative cosmological model of the world was showed by him in the article "General cosmology and general theory of relativety" (1917). Einstein's Universe living according ganeral theory of relativity (GTR) is static and changable. It has a finite mass i.e. finite number of stars galaxies and finitevolume. Einstein's system was terned on to be finite but endless without walls and space "out of walls".
