Sima Markovi´ c Theory of relativity Introduction 1924 - Teorija relativiteta - popularno nauˇ cna skica Mihailo Petrovi´ c (Theory of relativity, a popular-scientific sketch) Sima Markovi´ c General audience Milutin Milankovi´ c He glorifies mathematics often and compare it to the highest men’s achievements. Part 1. Special theory of relativity, pages 6 - 45. Part 2. General theory of relativity, pages 46 -80. He discussed also relation between the general theory of relativity and cosmology. He explains that the universe occupies a closed but unbounded space. As an application of the theory he deduced a formula of the size of the universe which depends only on the density ρ of the matter in the universe. Ž. Mijajlovi´ c, N. Pejovi´ c, V.
