Waclaw Sierpiński - budovatel novodobé matematické vědy v Polsku
Cet article traite d’un aspect de la controverse qui a opposé Hobbes et Wallis dans la deuxième moitié du xviie siècle, celui portant sur l’angle de contact. Wallis a publié deux traités sur l’angle de contact, l’un en 1656, l’autre en 1685. Entre ces deux dates sa position sur la question de l’angle de contact a sensiblement évolué. Durant la même période, il s’est opposé à Hobbes sur divers sujets de mathématiques, dont l’angle de contact. J’étudie les positions des deux protagonistes à travers...
François Viète considered most of his mathematical treatises to be part of a body of texts he entitled Opus restitutæ mathematicæ analyseos seu algebra nova. Despite this title and the fact that the term “algebra” has often been used to designate what is customarily regarded as Viète’s main contribution to mathematics, such a term is not part of his vocabulary. How should we understand this term, in the context of the title of his Opus, where “new algebra” is identified with “restored analysis”?...
This is a brief biography of the Polish mathematician Władysław Orlicz (mostly known for Orlicz spaces), one of the members of the famous Lwów School of Mathematics (Polish School of Analysis in Lwów) who after World War II organized the Poznań School of Mathematics. This biography also includes his scientific achievements and many official scientific activities (honors and awards, membership in various scientific societies and editorial boards). There is a special section about Orlicz's connection...
