Czesław Białobrzeski

Czesław Bialobrzeski ( born August 31, 1878 in Powszechonie in Jaroslaw, Russia, † October 12, 1953 in Warsaw) was a Polish theoretical physicist and astronomer.

Bialobrzeski studied from 1896 to 1901 at the Kiev University and from 1908 to 1910 with Paul Langevin at the Paris Collège de France. At that time he was still working mainly experimentally. In 1913, he handed in a Kiev his master's thesis. In 1914 he was offered the Chair of Experimental Physics at the Jagiellonian University, but he could not compete because of the First World War. Meanwhile, he transferred to theoretical physics. In 1919 he went back to Poland, was initially a year in Krakow and then Professor of Theoretical Physics at the University of Warsaw. He was a member of the Polish Academy of Sciences ( PAU ) in 1921, the Polish Academy of Sciences ( PAN) in 1952, the Warsaw Scientific Society from 1922. 1934 to 1938 he was chairman of the Polish Physical Society.

He is the author of about 100 papers on thermodynamics, relativity, quantum physics, structure and evolution of stars, spectrography, astrophysics and philosophy of physics.

Bialobrzeski was the first to point out the role of radiation in the stability of stars, in a work of 1913. Although It took place in Poland, for example, the attention of Marian Smoluchowski, but internationally she was handling the issue through the famous astrophysicist Arthur Eddington made ​​three years later in the shadows and Bialobrzeski claim came from a few exceptions into oblivion. In 1931 he published the book La Thermodynamique des Etoiles in Paris.

Among his students was Myron Mathisson.
