Jorge Mira Pérez (Coruña, 1968), is graduate in Physics by the University of Santiago de Compostela (1991), European PhD in Physics (1995). He is currently Full Professor of Electromagnetism at the School of Physics of the University of Santiago de Compostela. Apart from his scientific production, he is developing a very active role in the field of scientific knowledge dissemination through television, radio and written media.

summary:

The Belgian physicist-mathematician and Catholic priest Georges Lemaître (1894-1966) was one of the most acute experts on the theory of relativity proposal by Albert Einstein between 1905 and 1915. After analysing the equations of general relativity (those that describe the current paradigm of gravitation), he came to the conclusion that the Universe is expanding and even obtained the so-called Hubble law (2 years before Edwin Hubble himself), which quantifies this expansion. On the basis of this expansion, in 1931 he proposed what he called the hypothesis of the primordial atom, the first formulation of the Big Bang. In the search for tools to obtain experimental evidence, in the following years he developed a work that led him to pioneer numerical calculation programming techniques in Europe.
