In the development of television, many scientists played an important role, contributing to the part where their knowledge was most needed. Rosing is a vivid example of how an inquiring mind pushed to learn, to understand the wisdom of physics, electricity. Having created a television transmission of images, he did what is now considered commonplace - along with the sound, a picture appeared on the TV. What is the past of the famous engineer-inventor and what other merits are attributed to Boris Rosing in this article.
The origin of the scientist
The Rosing family has noble roots. During the reign of Peter the Great, active construction of cities, shipyards, and ships was launched. This required a lot of specialists in narrow areas, and Russia was happy to accept new people in its state. So Peter Rosing and his family appeared in the empire and stayed there to live, as many of their compatriots did later. The Dutch roots were not forgotten, the surname highly values the past and education in general. Boris Rosing's father, Leo, was an official. Performing his duties with all responsibility, he received the position of state adviser, after which he resigned.
The mother of the future scientist, Lyudmila Fedorovna, also did not have the reputation of being uneducated: being a housewife, she could freely speak three languages, she knew how to manage the household. On May 5, Boris L. Rosing was born; influential St. Petersburg became his hometown. He approached training responsibly, in 1887 he graduated from high school with an award - a gold medal.
The beginnings of a young scientist
Having chosen the exact sciences in his own way, the young man entered Petersburg University at the Faculty of Physics and Mathematics, which in 1891 he graduated with a diploma of the first degree. At this, he didn’t part with the university forever - a successful student, Boris Lvovich was left to become a professor. In 1892, he chose the Petersburg Technological Institute as his place of work, where he taught for the next 3 years. In 1895 he began teaching students at the Konstantinovsky Artillery School.
It is interesting that Boris L. Rosing was of the opinion that everyone was worthy of higher education, while many professors preferred to study only with male students. Supporting St. Petersburg women's polytechnic courses, he became dean at the Electromechanical Faculty. As a professor, he began to notice problems in the electronic transfer of images - mechanical scanning made it possible to transfer photographs, but she still had many shortcomings. So the idea came up to create the first electronic recording method.
The essence of inventions
Rosing Boris Lvovich always put inventions an order of magnitude higher than teaching and working as a teacher. The essence of his work came down to finding a way to transfer pictures to a distance. Realizing the great importance of the fruits of his work, Boris Lvovich received a patent not only in Russia, but also in England, America, Germany. In addition, the scientist was attracted by the question of what processes occur during the phenomenon of magnetism between two objects. So, he chose the processes that occur in two bodies during magnetization reversal as his theme for his dissertation at the end of the university. Later, Rosing tried to derive a formula for lengthening the wire, as he noticed changes in its length during magnetization reversal.
Knowledge in the field of magnetism allowed him, like many Russian inventors, to work on another problem. Boris Lvovich was thinking about creating a whole system of batteries with a moving layer of electrolytes. In addition, the use of electric energy would be more economical than thermal, and therefore the conversion of one type of energy into another could solve the problem of the lack and rational use of heat.
The advantage of knowledge in several areas
The above works do not exhaust the merits of Boris Lvovich. He worked on an electrical alarm system that could fit the work of fire stations, command telegraphs, and telephone exchanges. The advantage of such alarms was automatic shutdown, which was very convenient in large enterprises.
Many knowledge in the field of the study of electricity and magnetic fields was not available in Russian, but he inherited not only his father's thirst for knowledge of mechanics and mathematics, but also the respect for foreign languages that his mother had. Boris Rosing knew several of them, so he could stay up to date with the latest inventions. His reviews, essays, and articles on physics textbooks in foreign languages were published in the journal Electricity.
Electric telescope
This term was distributed much earlier than television. Boris Lvovich began working on electric telescopy, in his own words, in 1897. Already then, various solutions were proposed in different countries: the use of mechanical devices to scan images to elements. Russians invented mainly used the simplest optical-mechanical devices. Boris Lvovich saw in them a huge number of shortcomings after several years of research.
Boris Rosing saw television only if the inert systems were replaced by the inert ones. But such a system still needs to be searched. Boris Lvovich searched among foreign discoveries, but found in his laboratory, at the Technological Institute. There was an oscilloscope with a cathode ray tube that caught an electron beam, and complex figures appeared on the screen. It was she who became the basis for the discovery of a new method of transmitting images. Later, after studying the photoelectric properties of other substances, Boris Lvovich formed a whole system. Now television uses the same methods that a Russian scientist developed so long ago.
Society pays tribute
10 years of work was required to create such a system, which would not have significant flaws. Rosing did not expect material support, and it did not exist. Throughout the time of research, he improved his brainchild. So already after 1912, when the Russian Technical Society deservedly evaluated the result of its work and awarded a gold medal (for achievements in electrical telescopy), Boris Rosing continued to work on the system. He replaced the gas-filled tube with a vacuum, applied the properties of a longitudinal magnetic field, and more than once changed the number of ampere-turns of the coil.
In 1924, paying tribute to the merits, the Lenin Experimental Electrotechnical Laboratory invited Boris Lvovich as a senior researcher. But the scientist did not stop there. In 1924-1925, machines were already produced to facilitate the orientation of the blind. The laboratory allowed improving the Galilean binoculars and photographing sound (the basis for creating devices for the blind).
Further activities
The Physics and Mathematics Society, which Boris Lvovich created in 1920, continues to deal with current problems at that time, without ceasing to function even during the famine of 1922. As chairman of this society, Boris Rosing was given the opportunity to create a report on vector monology, the proposal of a simplified formula created on the basis of the Amsler planimeter. In 1923, the researcher’s book, “Electrical Telescope. Immediate tasks and achievements. ”
The political system of the USSR did not spare anyone at that time: in 1931, the scientist was arrested on charges of "for helping counterrevolutionaries." It was a period of repression of the intelligentsia (including Russian inventors). The fact that he gave money to a friend on loan was regarded as malicious intent. Only thanks to the intercession of strong friends Boris Rosing was transferred to Arkhangelsk.
Big inheritance
A brain hemorrhage in 1933, on April 20, cut short the life of Boris Lvovich. He died at the age of 63, was buried in Arkhangelsk. Studies of this person did not go unnoticed. As he himself expressed in 1925 about his inventions: “The time will come when electric telescopy will spread everywhere and become as indispensable as a telephone.” And so it happened.
Biography of Boris Rosing is no less interesting than his invention. The formation of a strong personality, a scientist, thirsting for knowledge, clearly shows that great people are not born, but become. The inventions of Boris Rosing made it possible to look into the depths of the ocean, to take out images of the bowels of the Earth from its most secret places, and to see this for both professors and schoolchildren.
