Karl Ferdinand Brown - a famous German physicist, winner of the Nobel Prize (1909, together with Guglielmo Marconi). Actively studied the technical application of electromagnetic waves.
Biography
The future scientist was born in June 1850 on the sixth day in the "cradle of Catholicism", the small German town of Fulda. The father of little Karl was an official in Hesse, which made it possible to attach the boy to the local gymnasium without any problems. After receiving secondary education, Brown went to Margsburg in 1868, where he entered the Philippe University, the first Protestant university in Germany. The very next year, Brown received an offer to work in the laboratory from Heinrich Magnus, the young scientist without hesitation accepted this offer and moved to Berlin.
Career
After graduation, the promising physicist had many ideas and even more financial problems. In order to somehow correct his plight, Karl in 1873 passed the exam for the post of teacher of the gymnasium. The following year, he began working as a mathematics teacher at the St. Thomas school in the city of Leipzig. Workload at school was relatively low, which allowed the scientist to engage in his main activity - the study of fluctuations in electric current.
In 1874, he made his first discovery in the field of electricity - he was the first to notice that different metals have different resistance and conductivity of electric current, and carefully studied this phenomenon.
In 1877, Brown returned to the University of Marburg, where he became professor of theoretical physics. After working there for only three years, he again moves. This time to Strasbourg, where he settles in the University of Karlsruhe. Despite frequent travels, Brown has always won the attention and respect of his students. Largely due to the simple and understandable even to the amateur form of presentation. In 1875, he even published his own textbook, Young Mathematician and Naturalist. His most famous students were Leonid Mandelstam and Nikolai Papaleksi, who later became pioneers of the Russian school of high-frequency technology.
Brown tube
Karl Brown gained real fame and recognition thanks to his invention - the Brown tube, which became the basis for the creation of picture tubes. The first use of Brown tubes began when creating oscilloscopes, but after changing and finalizing the design, picture tubes became the main and integral part of televisions. In addition, the scientist's works were used in the development of intelligent antennas and radars.
