Mathematical and Physical Journal for Secondary Schools November 2002. [antikvár]

KöMaL What is KöMaL? It was more than a hundred years ago that Dániel Arany, a high school teacher from the city of Győr, decided to found a mathematical journal for high school students. His goal was "to give a wealth of examples to students and teachers". The journal's first edition appeared on January 1, 1894. Prom that time several generations of mathematicians and scientists developed their problem-solving skills through KöMaL. The best solutions with the names of the 14-18 year-old authors are printed in the periodical. KöMaL regularly reports on national and international competitions, prints articles on interesting results in mathematics and physics, and includes book reviews. For more than 30 years all the new problems have appeared in English as well as Hungarian in the journal. This means thousands of mathematics and physics problems and exercises in English. At present the journal is published by the János Bolyai Mathematical Society and the Roland Eötvös Physical Society with the financial support of the Ministry of Education in 5000 copies. The periodical "KöMaL — Középiskolai Matematikai és Fizikai Lapok" appears in Hungarian language 64 pages a month 9 times a year. This periodical "KöMaL", that you are reading now, appears in Enghsh language two times a year. This is the first edition. The most interesting problems end articles from the homepage of KöMaL are collected and printed. The main goal of the periodical KöMaL to show the content that is open for students. We are waiting for you. Let us think. On János Bolyai's Bicentennial János Bolyai is one of the greatest figures of Hungarian and universal science. When mentioning his name, one always thinks of his inventive achievements in geometry. This is wholly legitimate, because with the creation of absolute geometry and non-Euclidean geometry in particular, he opened up a new chapter in the history of science. One can rightly assert that few inventions had so great an impact on the development of scientific world-view as that of Bolyai's geometrical invention. His only work published during his lifetime, The Absolutely True Science of Space, was enough to eternally inscribe his name in the history of mathematics. Until recently we used to think that we had a complete knowledge about his life-work. However, the research works of the last decade have shown that concerning the wide problematics of number theory and the question of solubility of algebraic Mathematical and Physical Journal for Secondary Schools, SOOS/1
