Many scientists played an important role in the development of television, making their contribution to the part where their knowledge was most needed. Rosing is a vivid example of how an inquisitive mind pushed to study, to understand the intricacies of physics, electricity. Having created a television transmission of images, he did what is now considered commonplace - along with 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
Rosing family has noble roots. During the reign of Peter the Great, active construction of cities, shipyards, and ships was launched. This required many 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 later did. The Dutch roots were not forgotten, the surname highly values the past and education in general. Boris Rosing's father, Leo, was an official. Carrying out their duties withwith all responsibility, he received the post of State Councilor, after which he resigned.
The mother of the future scientist, Lyudmila Fyodorovna, was also not reputed to be uneducated: being a housewife, she could speak three languages fluently, and ran the household competently. Boris Lvovich Rosing was born on May 5, influential St. Petersburg became his hometown. He approached training responsibly, in 1887 he graduated from the gymnasium with an award - a gold medal.
Beginnings of a young scientist
Having chosen the exact sciences as his own, the young man entered St. Petersburg University at the Faculty of Physics and Mathematics, from which he graduated in 1891 with a diploma of the first degree. On this, he did not part with the university forever - a successful student, Boris Lvovich, was left in order to become a professor. In 1892, he chose the St. Petersburg Institute of Technology 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 Lvovich Rosing was of the opinion that everyone deserves higher education, while many professors preferred to study only with male students. Supporting the St. Petersburg Women's Polytechnic Courses, he became dean at the Faculty of Electromechanics. As a professor, he began to notice problems in electronic transmission of images - mechanical scanning allowed the transmission of photographs, but it had many drawbacks. So the idea was born to create the first electronic recording method.
The essence of inventions
Rosing Boris Lvovich always put inventions an order of magnitude higher than teaching, working as a teacher. The essence of his work was to find a way to transmit pictures over a distance. Understanding the great significance of the fruits of his labor, Boris Lvovich received a patent not only in Russia, but also in England, America, and 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 occurring in two bodies during magnetization reversal as his topic for a dissertation at the end of the university. Later, Rosing tried to derive a formula for the elongation of a 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 thought about creating a whole system of batteries with a moving layer of electrolytes. In addition, the use of electrical energy would be more economical than thermal energy, and therefore the conversion of one type of energy into another could solve the problem of lack and irrational use of heat.
Multiple Knowledge Advantage
The above works do not exhaust the merits of Boris Lvovich. He worked on an electrical signaling system that could fit the work of fire stations, command telegraphs, telephone exchanges. The advantage of such alarms was the automatic shutdown, which was very convenient on largeenterprises.
Many knowledge in the field of researching electricity and magnetic fields was not available in Russian, but he inherited not only his father's thirst for knowledge about mechanics and mathematics, but also his mother's respect for foreign languages. Boris Rosing knew several of them, so he could stay up to date with the latest inventions. His reviews, abstracts, articles on physics textbooks in foreign languages were published in the Electricity magazine.
Electric Telescope
This term was common much earlier than television. Boris Lvovich began to work on electric telescoping, in his own words, in 1897. Even then, various solutions were proposed in different countries: the use of mechanical devices for scanning images into elements. The Russians invented mainly using the simplest optical-mechanical devices. Boris Lvovich saw a huge number of shortcomings in them after several years of their research.
Television Boris Rosing saw success only if inert systems are replaced by inert ones. But such a system is yet to be found. Boris Lvovich searched among foreign discoveries, but found them in his laboratory, at the Technological Institute. There was an oscilloscope with a cathode ray tube that caught an electron beam, and complex shapes appeared on the screen. It was she who became the basis for the discovery of a new way of transmitting images. Later, after studying the photoelectric properties of othersubstances, Boris Lvovich formed a whole system. Now television is using the same methods that the Russian scientist developed so long ago.
Society pays tribute
10 years of work was required to create such a system that would not have significant flaws. Rosing did not expect material support, and there was none. Throughout the time of research, he improved his offspring. So already after 1912, when the Russian Technical Society appreciated the result of his work and awarded him a gold medal (for achievements in electrical telescopes), Boris Rosing continued to work on the system. He replaced the gas-filled tube with a vacuum one, applied the properties of a longitudinal magnetic field, and repeatedly 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 made it possible to improve Galilean binoculars and photograph sound (the basis for creating devices for the blind).
Further activities
The Physical and Mathematical Society, which Boris Lvovich created in 1920, continues to deal with problems that were relevant at that time, without stopping functioning even during the famine of 1922. While serving as chairman of this society, Boris Rosing had the opportunity to create a reportabout the vector monologue, the proposal of a simplified formula based on the Amsler planimeter. In 1923, the researcher's book, Electric 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 "helping counter-revolutionaries." It was a period of repression of the intelligentsia (including Russian inventors). The fact that he loaned money to a friend was regarded as malicious intent. Only thanks to the intercession of strong friends, Boris Rosing was transferred to Arkhangelsk.
Great Inheritance
A brain hemorrhage in 1933, on April 20, cut short the life of Boris Lvovich. He died at the age of 63 and was buried in Arkhangelsk. This man's research has not gone unnoticed. As he himself put it in 1925 about his inventions: "The time will come when the electric telescope will spread everywhere and become as indispensable as the telephone." And so it happened.
The biography of Boris Rosing is no less interesting than his inventions. The formation of a strong personality, a scientist, thirsty 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 bring images of the bowels of the Earth from its most secret places, to see it both for professors and schoolchildren.
