Ludwig Boltzmann. Pionero de la ciencia del siglo XX.

The scientific legacy of the physicist Ludwig Boltzmann (1884-1906) has been one of the most extensive and complete in the modern period. It was developed in the context of profound transformations in the conceptions of the scientists about the classical theories. His scientific labour was a bridge between the Newtonism and the new Physics (quantistic and relativistic Physics). His research in statistical mechanist, Thermodynamics and Electromagnetism would be enough for considering him one of the most important physicists of the final of the XIX century and the early XX century. Additionally, his scientific work in Physics was complemented with important contributions to the Philosophy of Science, the debate concerning the scientific theories, the role of the hypothesis and the validity of the classical mechanics as an absolute method in Science. His polemics with the main supporters of the Empire criticism and Energetism, were key points in the demolition of the pseudo-scientific positions and besides, in the ending of the "Physics Crisis". Moreover, Boltzmann a long his life performed an intense pedagogical labour in some of the main Austrian universities. The last statement demonstrates the extension and depth of his intellect.
