In the scholarly output of Polish mathematicians of the 20th century one can find numerous examples of functions and sequences of functions with unusual or unexpected properties. This paper discusses certain results of Wacław Sierpiński, Stanisław Saks, Stefan Mazurkiewicz, Hugo Steinhaus, Stefan Banach, Witold Wilkosz, Stanisław Ruziewicz, Antoni Zygmund, Józef Marcinkiewicz, Zygmunt Zahorski,...
The paper includes English translations (together with original Latin versions) of three papers of Adam Adamandy Kochański (1631-1700), originally published in Acta Eruditorum in 1682 (“Solutio theorematum”), 1685 (“Observationes cyclometricae”), and 1686 (“Considerationes quaedam”). The translation is as faithful as possible, often literal, and it is mainly intended to be of help to those who wish...
The notion of the number line was formed in 20th century. We consider the generation of this concept in works by M. Stifel (1544), Galileo (1633), Euler (1748), Lambert (1766), Bolzano (1830-1834), M´eray (1869–1872), Cantor (1872), Dedekind (1872), Heine (1872) and Weierstrass (1861-1885).
The present text contains information about the conference Polish School of Mathematics in the interwar period, which took place in Lens, France on 21-22 November 2014.
Mark Kac (1914-1984) was born in the then Russian and now Ukrainian city of Kremenec, also the birthplace of the renowned violinist Isaac Stern. In 1922, when he was eight years old, the town became part of Poland and assumed the name Krzemieniec. Because he received virtually all of his education in Polish and was a Polish citizen on arriving, in 1938, in the United States, he always considered himself...
The present text consists of reflections about the book Karl Löwner and his Student Lipman Bers – Pre-war Prague Mathematicians by M. Bečvářová and I. Netuka. The book, published in the series Heritage of European Mathematics by European Mathematical Society (Zürich, 2015), treats the mathematical community of Prague before World War II and the fates of mathematicians of Jewish descent fromCentral-Eastern...
Rapid development and wide application of computers created very important research discipline-- computer science\footnote{informatics}. Computer science in Wrocław has its roots primarily in mathematics. The doubtless merit of mathematicians working in Wrocław is creating a very favorable atmosphere for growth of computer science. The author of these memoirs was very active participant in the creation...
Autor rozpoczyna swą książkę słowami: This book is intended for those interested in the history of mathematics or statistics and more or less acquainted with the latter. It will also be useful for statisticians. My exposition is based, in the first place, on my own investigations published over some 35 years and monograph (2009) and I stop at the axiomatization of probability and at the birth of the...
The text gives an account of two special sessions on the Joint Mathematics Meetings (San Antonio, Texas, USA) in January 2015, devoted to Polish mathematics.
The decree that officially brought Lodz University of Technology into being was signed on 24 May 1945. The university's first faculties were Mechanical Engineering, Electrical Engineering and Chemistry. Among researchers employed there were two mathematicians: Witold Pogorzelski and Edward Otto. Lectures of mathematics were provided by the Chairs of Mathematics and initially were shared by all faculties...
The article presents the scholarly, didactic, organizational and social activities of Professor Lech Dubikajtis (1925-2014). The author knew the Professor since her high school days, as he was her geometry teacher in an advanced placement class in Torun. Besides, the article contains the list of scholarly and didactic publications by L. Dubikajtis.
This is a review of genesis of „ε-δ" language in works of mathematicians of the 19th century. It shows that although the symbols ε and δ were initially introduced in 1823 by Cauchy, no functional relationship for δ as a function of ε was ever ever specified by Cauchy. It was only in 1861 that the epsilon-delta method manifested itself to the full in Weierstrass de_nition of a limit. The article...
In the article, there are presented some remarks connected to the book “Matematika na Nĕmecké univerzitĕ v Praze v letech 1882–1945” by M. Bečvářova. The problems mentioned in the title are first discussed in a comprehensive manner based on numerous distributed sources.
Pre-war academic staff in Poland, seriously curtailed during World War II, could not meet satisfactorily post-war demands of quickly expanding academic schools. Help has been provided by the pre-war school teachers. The article describes the situation in the field of mathematics, offering fates of over 40 school teachers of mathematics who joined universities and polytechnics, and giving some general...
This is an essay on the historical landmarks leading to the study of principal confgurations on surfaces in R^3 , their structural stability and further generalizations. Here it is pointed out that in the work of Monge, 1796, are found elements of the qualitative theory of differential equations, founded by Poincaré in 1881. Recent development concerning the space R^4 are mentioned. Two open problems...
The current text is a review of an essay titled „Dwie Warszawy” (Two Warsaws). „Dwie Warszawy” is one of four essays in history of mathematics by Jerzy Mioduszewski. In all of them the author shows, with great discernment, not only the crucial problems of development of mathematical notions, but also cultural as well as political conditions of practising mathematics and its involvements in historical...
Dramatic historical events of the last two centuries in Poland (partitions, uprisings, wars, oppressions etc.) heavily influenced fates of all people, including mathematicians. Distinguishing several periods by the eventful years 1795, 1832, 1862, 1913, 1919, 1939, 1945, 1952, 1989, the author recalls some Polish mathematicians for each of them (in total over 50) to explain what they could or could...
