Samu from Borbely

from Wikipedia, the free encyclopedia

Samu von Borbely (born April 23, 1907 in Thorenburg , † August 14, 1984 in Budapest ) was a Hungarian-German engineer and mathematician and professor of applied mathematics . He became known as an engineering mathematician in the fields of flow theory , flow technology and ballistics .

Live and act

Samuel Borbely (Georg Samu (el) von Borbély) was born a Hungarian in Thorenburg ( Turda ) in Transylvania , which belonged to Romania . He attended grammar schools in Thorenburg and Klausenburg ( Cluj ), but had to take his Abitur examination in Kecskemét ( Hungary ) in 1926 because he was not admitted to the Abitur as a Hungarian citizen in Romania. His studies of mathematics and mechanical engineering led him to the Technical University of Berlin-Charlottenburg , which he graduated in 1933 as a graduate engineer (Dipl.-Ing.).

When he started his career from 1929 to 1934 he worked as an honorary assistant at the Technical University of Berlin with the applied mathematician Rudolf Rothe , who shaped him for life in his practice-oriented scientific mindset.

He then worked as a research assistant at the Aviation Institute of the Technical University of Berlin until 1941. Here he worked on a fluid engineering dissertation and received his doctorate in 1938 as a doctoral engineer (Dr.-Ing.). He also worked as a lecturer in the postgraduate engineering training from 1930 to 1941 and gained extensive teaching experience.

In 1941 he moved to the Franz Josef University in Klausenburg as a research assistant. Here he completed his habilitation in 1943 and then worked as a professor until he was imprisoned by the German occupying forces in May 1944. He was trapped in Berlin and Sopronköhida , but managed to escape in December 1944; he saw the end of the war in Budapest . In 1945 he took over the management of the Mathematical Institute of the Bolyai University in Cluj , where he worked as dean from 1948 to 1949 , until he was finally dismissed without notice because of his Hungarian citizenship.

Borbely was elected as a corresponding member of the Hungarian Academy of Sciences as early as 1946 . So it was only natural that he should move back to Hungary in 1949. He took over the management of the Mathematical Institute of the Technical University in Miskolc until 1955, and then until 1978 he headed the Mathematical Institute at the Mechanical Engineering Faculty of the Technical University of Budapest . In between he worked as a visiting professor : from 1960 to 1964 he held a visiting professorship at the Otto von Guericke University of Technology in Magdeburg and was at the same time director of the Mathematical Institute, succeeding Felix Wittig . Here he was particularly concerned about the application orientation of the institute as well as promoting young talent. At the Technical University of Berlin-Charlottenburg, where he originally studied and obtained his doctorate, he was also a visiting professor for applied mathematics in the academic year 1968/69.

In 1978 the Technical University of Miskolc awarded him an honorary doctorate ( Dr. hc ) for his scientific merits . The Hungarian Academy of Sciences elected him a full member in 1979.

Borbély has submitted nearly 50 publications, research reports and articles on practical mathematics, as well as contributions to textbooks. His main areas of work were flow theory, flow technology and ballistics.
