Fifty years of Applications of Mathematics
Rok 2022 je několikanásobným jubilejním rokem pro matematickou olympiádu v České republice, potažmo v Československu. Do souvislosti jsou dána i jubilea, která matematické olympiádě předcházela. Vzniká tak zajímavý komplex událostí, které proběhly v letech končících číslicí 2.
Cet article examine une activité procédurale dénommée «jeux de ficelle» et pratiquée dans de nombreuses communautés de tradition orale. À partir de l’analyse de certaines sources ethnographiques, nous en présenterons deux modes de conceptualisation. Muni de ces outils conceptuels, nous montrerons que la création des jeux de ficelle provient d’un travail intellectuel autour des concepts de «procédure», d’«opération», de «sous-procédure», de «transformation» et d’«itération». Ce travail a consisté...
This paper sets out to examine some of Riemann’s papers and notes left by him, in the light of the “philosophical” standpoint expounded in his writings on Naturphilosophie. There is some evidence that many of Riemann’s works, including his Habilitationsvortrag of 1854 on the foundations of geometry, may have sprung from his attempts to find a unified explanation for natural phenomena, on the basis of his model of the ether.
This paper presents a classification of statistical models using a simple and logical framework. Some remarks are made about the historical appearance of each type of model and the practical problems that motivated them. It is argued that the current stages of the statistical methodology for model building have arisen in response to the needs for more sophisticated procedures for building dynamic-explicative types of models. Some potentially important topics for future research are included.
