According to info got by StampNews.com Romfilatelia dedicated its next stamp issue Great Inventors to some of the representative figures of world scientific and technical progress, the four stamps illustrating Leonardo da Vinci, Thomas Alva Edison, Nikola Tesla and Albert Einstein. The issue was released on the 17th of December and is now available for purchasing.
The stamp with the face value of lei 3.30 depicts Nikola Tesla (1856 - 1943) along with a picture of the induction motor supplied with alternating current. The Serbian-American inventor's technical imagination, supported by a fantastic capacity of concentration and intense motivation was in full display right from an early age: he believed that one day he would be able to photograph people's thoughts. Tesla left behind more than 200 inventions. His creations included extraordinary achievements, such as the electric arc, the AC motor and AC systems. He is also famous for the ignition coil for high frequency alternating currents.
On the stamp with the face value of lei 3.60 is illustrated the portrait of the American inventor Thomas Alva Edisson (1847-1931), known as "The magician of Menlo Park" together with his most famous invention: the incandescent filament bulb, epochal discovery without which we cannot imagine the present. A true autodidact, Edison contributed to the wellbeing of humanity through a series of inventions in telegraphy, telephony, electricity, cinematography and mechanical sound recording. He has kept his belief in self-improvement throughout his life, this accompanying him permanently in his experiments designed to contribute to the scientific and technological development of his time.
On the stamp with the face value of lei 4.30 is represented the portrait of the great theoretical physicist Albert Einstein (1879-1955) with the famous equation E = mc² of the Theory of Relativity, reproduced on the postmark.
A German-born American physicist, he showed a curiosity for nature and an innate ability to understand difficult mathematical concepts from a young age. After 1919, Einstein, famous worldwide, advocated international disarmament and a world government. Although Einstein was much devoted to political and social causes, science was always on the forefront, thus confirming one of the ideas in which he believed, namely that only the discovery of the Universe's nature would have a lasting meaning. His writings include: Relativity: the special and general theory(1916), The world as I see it(1934), The Evolution of Physics(1938) and From my past years (1950).
The stamp with the face value of lei 14.50 depicts the "Master of the Renaissance", as Leonardo da Vinci was also called (1452 - 1519), along with one of his creations, a mechanical system to irrigate the farmland. Leonardo da Vinci is part of the Renaissance movement, standing out among other inventors of the time through both the difference in method and vision, and his skills that made him excel in many areas such as painting, sculpture, architecture or engineering. His main inventions are different types of machines used both for the protection and the siege of a city, his work having been closely related to the socio-political context of the Italian states and the conflict relationship between them.
