Ludwik Birkenmajer

Ludwik Antoni Birkenmajer (18 May 1855 - 20 November 1929), Polish historian of science, physicist, astronomer, professor of the Jagiellonian University.

Biography

Descended from the German family settled in Galicia (Southern Poland) during the time of the Napoleon wars, later a part of the Austrian Habsburg Empire. He was the son of Józef Herman and Petronela de domo Stefanowski. Educated in the Franz Joseph High School (so called Gymnasium at that time) in Lvov (1865–1873), than studied physics, chemistry and mathematics at the Kraków University till 1878. Supplementary studies in Vienna (1879–1880). In 1879 he defended his Ph. D. thesis in Kraków based on the study: On general methods of integration of the algebraic and transcendental functions (in Polish: O ogólnych metodach całkowania funkcyj algebraicznych i przestępnych). Since 1878 for nearly two decades was a teacher of mathematics and physics in the renowned agricultural school in Czernichów near Kraków. In 1897 he started his academic career at the Jagiellonian University, where he continued to work till the end of his life. At the beginning he was an extraordinary professor, than - since 1919 – he became an ordinary professor and lecturer of the history of mathematics, physics, astronomy and physical geography, simultaneously being a Chair of the History of Exact Sciences. In 1893 he was elected the correspondent member of Kraków Academy of Sciences and Letters, and in 1927 became its regular member. He was one of the organizers of the Library Commission of the Academy (1901). In 1910-1913 he held the post of the secretary of its Commission for the History of Mathematical and Natural Sciences. Since 1918 the Academy was renamed into the Polish Academy of Sciences and Letters. Birkenmajer was also the member of Scientific Society in Toruń (Thorn) and of the International Astronomical Union in Oxford. In 1923 took significant part in the jubilee celebration of the 450 anniversary of the Copernicus birth with the series of lectures presented in Kraków, Toruń, Poznań and Warsaw.

Scientific output

He analyzed the Copernicus main work De revolutionibus orbium coelestium, and came to the conclusion that the Heliocentric Theory was created by Copernicus before he got acquainted with the Ptolemy Almagest. He also elaborated the biographical materials and records of the Copernicus life till 1500, as well discovered - an unknown earlier - letter of the astronomer to the king Sigismund I the Old concerning the Teutonic Order. He also studied scientific output of Marcin Bylica of Olkusz, and prepared the history of geodesy and gravimetry. Prepared the scientific edition of Tito Livio Burattini Misura universale (1897), the Practical geometry of Marcin Król (1895), as well as the Commentariolum super theoreticas planetarum of Albert of Brudzewo (1900). Moreover in his academic interests he studied theoretical physics, astronomy, algebraic functions and geophysics. In 1883 he won the prize of the Kraków Academy in geometry for solving what would (17 years) later be known as Hilbert's third problem, and later received Swedish Order of the Polar-Star, and Polish Commander Cross of the Republic of Poland (1924).

Birkenmajer family

Ludwik was the founder of the renown Polish family of scholars. He was married Zofia (Sophie), the daughter of Franciszek Karliński, the professor of astronomy in the Jagiellonian University, and inherited his library embracing mostly the books on mathematics and physics. They had three sons: Aleksander Ludwik (historian of culture and exact sciences, and bibliologist), Józef (poet, interpreter and literature historian), and Wincenty (Polish philologist, teacher and renown Tatra Mountains-climber). His grandson is Krzysztof Birkenmajer (professor of geology, member of the Polish Academy of Sciences). In 2011 the Institute for the History of Science of the Polish Academy of Sciences received the name of father and son: Ludwik & Aleksander Birkenmajer.

gollark: Oh, right, the actual video: this is an amateur potatOS security researcher revealing a bug they found.

gollark: So the general and robust fix for this would be to stop doing I/O this way for anything but performance-sensitive and fairly robust (terminal, FS) I/O and API stuff, but PotatOS has so much legacy code that that would actually be very hard.

gollark: As it turns out, you can take a perfectly safe function with out of sandbox access and make it very not safe by controlling what responses it gets from HTTP requests and whatever.

gollark: And *another* Lua quirk more particular to CC is a heavy emphasis on event-driven I/O via coroutines.

gollark: The FS layer is actually fine, probably, apart from insufficiently flexible filesystem virtualization; the issue is that since this is really easy, many other potatOS features interact this way.
