Mathematical modelling of the tundish inertization practice [PDF]

open access: yesComputer Methods in Materials Science, 2014
The inertization practice for a 17.7 tons of steel continuous casting tundish has been studied by means of a threedimensional non-isothermal mathematical model. The model considers a single gaseous phase composed of argon and air.

Retrieval practice may not benefit mathematical word-problem solving

open access: yesFrontiers in Psychology, 2023
The retrieval practice effect refers to the fact that one or even multiple retrievals of memory content during the same period are more effective than repeated studying to promote future memory retention.

Visualization as an Intuitive Process in Mathematical Practice

open access: yesConatus - Journal of Philosophy
In the field of the philosophy of mathematics, in recent years, there has been a resurgence of two processes: intuition and visualization. History has shown us that great mathematicians in their inventions have used these processes to arrive at their ...

Problematising current forms of legitimised participation in the examination papers for Mathematical Literacy

open access: yesPythagoras, 2015
In this article we argue that in South Africa the current format of legitimised participation and practice in the examination papers for Mathematical Literacy restricts successful apprenticeship in the discipline of scientific mathematics and limits ...

The Geometry of Thought: Circling Through Concepts

open access: yesPhilosophies
The goal of this paper is to shed light on the nature of mathematical practice, i.e., on “doing mathematics”. It explores Gödel’s perspective, which offers an approach to understanding mathematics centered on concepts, objects, and structures.

Learning from Euler. From Mathematical Practice to Mathematical Explanation

open access: yesPhilosophia Scientiæ, 2012
In his "Découverte d'un nouveau principe de mécanique" (1750) Euler offered, for the first time, a proof of the so-called Euler's Theorem. In this paper I will focus on Euler's original proof and I will show how a look at Euler's practice as a ...

Lange on Mathematical Explanation, Grounding, and the Divergence Thesis

open access: yesCrítica
Mark Lange has defended the view that mathematical explanation and grounding explanation diverge. In this paper, I argue that at least one type of grounding relation is immune to his criticisms. After fixing a minimal separatist theory of ground, I show
