TRAIAN VUIA AND HIS KNOWLEDGE IN THE FIELD OF EXACT SCIENCES

Summary/Abstract: The Romanian inventor Traian Vuia (1872 –1950) was a pioneer of world aeronautics. He lived in Paris since 1902, and he became well acquainted with latest scientific discoveries, especially in the fields of exact sciences (mathematics, physics, chemistry) and inventics. He was particularly interested in the characteristics of particles resulting from the disintegration of radioactive elements. In order to make known in his own country the natural radioactivity and the separation of radium by Marie Curie and Pierre Curie (Nobel Prize 1903), Traian Vuia published in the newspaper “Drapelul” (“The Flag”) from Lugoj (Banat) on 27 January / 9 February 1904 the article “Radioactivity–Scientific Commentaries”. Characteristics of the radioactive elements radium, polonium, thorium, uranium, and actinium, as well as of the γ-rays and X-rays were offered to the readers. Traian Vuia also advanced the idea of using the thermic properties of radium for the heating of the buildings and for the making of thermic engines. The medical results obtained in the therapy of the lupus erythematosus and of cancer are mentioned too. The bibliographical sources of the inventor Traian Vuia are identified as follows: Annales de Chimie et de Physique; Comptes Rendus de l’Académie des Sciences, Paris; Mem. Acad. Sci., Paris; Marie Curie’s essential work Recherches sur les Substances Radioactives (Gauthier-Villars, Paris, 1904).
