    On the Mathematical Constitution and Explanation of Physical Facts

    Get PDF
    The mathematical nature of modern physics suggests that mathematics is bound to play some role in explaining physical reality. Yet, there is an ongoing controversy about the prospects of mathematical explanations of physical facts and their nature. A common view has it that mathematics provides a rich and indispensable language for representing physical reality but that, ontologically, physical facts are not mathematical and, accordingly, mathematical facts cannot really explain physical facts. In what follows, I challenge this common view. I argue that, in addition to its representational role, in modern physics mathematics is constitutive of the physical. Granted the mathematical constitution of the physical, I propose an account of explanation in which mathematical frameworks, structures, and facts explain physical facts. In this account, mathematical explanations of physical facts are either species of physical explanations of physical facts in which the mathematical constitution of some physical facts in the explanans are highlighted, or simply explanations in which the mathematical constitution of physical facts are highlighted. In highlighting the mathematical constitution of physical facts, mathematical explanations of physical facts deepen and increase the scope of the understanding of the explained physical facts. I argue that, unlike other accounts of mathematical explanations of physical facts, the proposed account is not subject to the objection that mathematics only represents the physical facts that actually do the explanation. I conclude by briefly considering the implications that the mathematical constitution of the physical has for the question of the unreasonable effectiveness of the use of mathematics in physics

    Between gate-keeping and support: Teachers’ perception of their role in transition

    This article discusses how teachers perceive their role in supporting and guiding students in transitions. Do teachers see themselves more as gatekeepers or as supporters? The analysis draws upon qualitative data collected in Germany, the Netherlands, Italy, and Finland. Based on the analysis of teachers' interviews, we developed three constellations of how teachers perceive their role in relation to supporting students: support focused on employability, support focused on access and opportunities, and support focused on students' well-being. We found that teachers tend to find a balance between all three constellations, but also that the education system (differentiated vs. comprehensive), patterns of collaboration with other youth professionals, and labor market conditions all influence their role.Development Psychopathology in context: clinical setting
