The paper is devoted to a story of the well-known Rolle's theorem: If the function is continuous on [a, b], differentiable in (a, b) and f (a) = f (b), then there exists in (a, b ) at least one point c such that f'(c) = 0. A history of the associated statements about the roots of a continuous function: If the function f is continuous on [a, b] and has different signs at the ends of the...
After regaining independence Polish educational system was organized according to the concept developed by teaching circles and based on the educational systems left by three different partitioners. During 20 years many corrections had been made until the introduction of the fundamental educational reform in 1932. In this article syllabi of mathematics taught in secondary school, their subsequent...
Teaching of trigonometry in secondary school in Poland have been conducted within a definite period of time. Introduced by the Commission of National Education, it existed as an independent branch of mathematics taught at school until the reform of 1966. In this article the changing range and methods of trigonometry teaching based on school textbooks’ content are being discussed. Trigonometry appeared...
Paul Erdös (1913-1996) was the second most productive mathematician in history(greater legacy had only Euler).He left 1548 works and the number of his co-authors,the largest in history,is about 500.About 600 papers of his,including the approximately 70\% co-authored, are discussed in the obituary published in Acta Arithmetica by A.Sarkozy (1997). This paper repeats, in many places, the information...

Praca jest kontynuacją mojego artykułu w Wiadom. Mat. 20 (1993). Różni się tym, że dotyczy całego dorobku Walfisza z teorii liczb, również uzyskanego po jego wyjeździe z Polski do Gruzji, jest natomiast mniej szczegółowe. Podobnie jak poprzedni artykuł i ten opiera się w dużym stopniu na artykule Lamadse (1964), który zawiera m.in. pełny spis prac Walfisza.

Zygmunt Zahorski was born in 1914. In 1932 he began his studies at the Faculty of Mechanics, the Warsaw Polytechnic intending to study aeronautical engineering. Two years later he joined to the Faculty of Mathematics at Warsaw University for parallel study (in slow motion) where he included two full years and, in the same time, a part of the third year course at the Polytechnic. The mathematical studies...
Towarzystwo Nauk Ścisłych w Paryżu istniało formalnie w latach 1870-1882. Jednak okres jego działalności należy rozszerzyć na lata 1852-1882, gdyż pierwsze publikacje z matematyki w Paryżu finansował Jan Działyński począwszy już od 1852 roku. Z wyjątkiem książki Norzewskiego, były to przede wszystkim książki Grakcha Henryka Niewęgłowskiego. Poniżej przytaczam część listów Niewęgłowskiego do Jana Działyńskiego...
Fundamentals of general algebra, also known as universal (universal algebra) appeared already in the nineteenth century. The article uses the term algebra general, a term disseminate Edward Marczewski. The subject matter of general algebra, on the initiative and under the direction of Edward Marczewski, she was very active in Wroclaw in the sixties of the twentieth century, mainly at the Mathematical...
