George (Gogu) Constantinescu (October 4, 1891 - December 11, 1965) was a Romanian scientist and engineer, often considered to be one of the most important Romanian engineers. He was responsible for creating a new field of mechanics, called "sonicity," which describes the transmission of energy through vibrations in fluid or solid bodies. He applied the new theory to numerous inventions: sonic, sonic hammer, sonic pomp and others. Among other achievements, there is also a pulling device among the propeller blades regardless of its speed and the first automatic gearshift. He has actively participated in the construction of English aircraft, the Bristol type, while he lived in England. He was the first to use reinforced concrete in the construction of buildings in Romania (among the buildings he built, we can mention: the Patriarchal Palace, the Athénée Palace Hotel and the Great Mosque in Constanta). Gogu Constantinescu was one of those brilliant minds, whose ideas have long outstripped his physical existence, but which today preserves its topicality, surprising by its accuracy, inventiveness and applicability. Gogu Constantinescu's account includes over 317 patents patented in the USA, Denmark, Switzerland, Austria, Germany, Great Britain, France, Romania, etc., as well as others that have never been published. A small calculation shows that since the first invention (1907), until the date of transition to eternity (1965), on average every 4 months a patent was made and if we count only the most prolific years, it results in invention per month. We can say that what Tesla did in electronics, Constantinescu succeeded in mechanics. If Nicolae Tesla invented and transmitted electromagnetic waves (electromagnetic oscillations) through the atmosphere, George Constantinescu invented mechanical sonic oscillations with which he transmitted sonic waves only through continuous media (tubes or pipes, water, oil, various liquids, air, gas, or full bars). Both transmit the waves (produced by oscillations), as well as the energy and power included in these waves, thus managing to transmit energy and power at small, medium, large, even very large distances, controlling and controlling the phenomena and processes from a distance or a large distance.
