life and work
After receiving private tuition in his parents' house in Rostov-on-Don, Simon Ratnowsky came to Switzerland at the age of 18, where he passed his Matura in Zurich and began studying philosophy at the University of Bern in 1903 . In 1907 he enrolled at the Faculté des Sciences of the University of Nancy , but in the same year he returned to Switzerland and graduated from the University of Geneva with a doctorate in 1910 .
In the Geneva laboratory, Charles-Eugène Guye Ratnowsky suggested that one of the fundamental questions of physics should be dealt with, namely to experimentally test the dependence of the mass of a body on its speed, as claimed by Albert Einstein . Ratnowsky carried out experiments with cathode rays for this purpose .
In 1910 Ratnowsky came to Zurich, where, in addition to further studying theoretical physics, he worked in the laboratory of the Swiss Federal Polytechnic . In 1912 he became Alfred Kleiner's assistant at the physics institute at the University of Zurich . Here he began the experimental work to prove the existence of ready electric dipoles in liquid dielectrics with it in 1913 at the University of Zurich as a lecturer of Physics habilitated . In recognition of his services, he was appointed adjunct professor in 1921.
In 1926, Ratnowsky, who had previously taught at the Zurich Cantonal School and at the private Matura school of Sinai Tschulok , was elected by the Cantonal Council of Zurich as Professor of Physics and Mathematics at the Winterthur Cantonal School. Since 1930 he has also held courses on the didactics of physical education at the University of Zurich .
