Romanian physicist
Among the new areas of physics there is plasma physics (as known this fourth state of matter - the others are solid, liquid and gas), i.e. the properties study of highly ionized gas. In this modern branch of science, a pioneer of Romanian physicist was Eugen Badarau. "The secret of great discoveries, he testified in 1967, is work and good observation, combined with a sense of perspective and intelligence." After secondary and high education studies in different cities, he became doctor in physics in 1912, with a thesis on dielectric constant of gases and gas mixtures.
He was two years assistant at the Institute of Experimental Physics, University of Pisa (1912-1914), for the period 1915-1918, is assistant to the known Russian physicist A. Ioffe, St. Petersburg University. His scientific work continued some time in this city, being, in turn, Director of the Institute of Physics of Leningrad (1918-1921) and professor of optics, then of fototehnics at university of the same city (1921).
Returning home, we found him Professor and Director of the Institute of Physics of Cernăuţi (1921-1934) and, for some time, Dean of Science Faculty of Cernăuţi. In 1934 he is professor, successor of physicist Const. Miculescu, University of Bucharest. In the capital, he worked the rest of your life, for teaching and management positions in the Institute of Physics of the Academy, and later as director of the Institute of Physics of Bucharest (1956-1970).
His research focused mainly on electric discharge in rarefied gas since 1921, launching the first investigations in our country in this area and organizing a real research into this direction, forming many physicists in laboratories created and led by E. Badarau.
He made well known contributions to the development of plasma physics, harmoniously combining experimental studies with theoretical ones. He was among the first scientists in the world that have been experimentally proved electronic emission of metals bombarded with positive ions, gave an original explanation to the electric luminescent discharge of the original lightning mechanism. He determined the ionization coefficient of mono-and polyatomic gases and studied the explosive potential and cold cathode lamps etc. Naturally, his experimental research led him to invent new measuring instruments with superior capabilities compared with existing ones at that time. Also, Eugene Badarau made valuable contributions in spectroscopy, semiconductor physics, acoustic and ultra-acoustic, some of his studies having practical applications in ultrasonic non-destructive testing of buildings and cars, in combating noise pollution, agricultural technique, etc.
Member of the Academy in 1948 and Chairman of the Acoustics Committee of the Academy, organized in his initiative, Eugen Badarau was a man of vast culture, a complete man, loving both science and art. Young, he sang on the violin in a quartet and enjoyed all his life the novel classics as Tolstoy and Dostoyevsky. Perhaps nothing better defines his believes as his own words: "We wanted to make my contribution to the dream of all humanity, a serene, beautiful life ".
He remains in the science history, primarily as pioneer in the study of electrical discharges in gases, in plasma physics.
