Newton's Idea and Practice of Unification

In this paper I try to capture Newton's notion and practice of unification (I will mainly focus on the Principia). I will use contemporary theories on unification in philosophy of science as analytic tools (Kitcher, Schurz and Salmon). I will argue that Salmon's later work on the topic provides a good starting point to characterize Newton's notion and practice. However, in order to fully grasp Newton's idea and practice of unification, Salmon's model needs to be fleshed out and extended

Test-retest reliability and validity of a child and parental questionnaire on specific determinants of cycling to school

This study examined the reliability of a newly developed child and parental questionnaire on specific determinants of cycling to school among 10-12 year olds. Validity of child reported distance, bicycle equipment and basic bicycle skills was also investigated. In total 211 children and 33 parents participated in this study. The reliability of the questionnaires was acceptable with results indicating reliability ranging from fair to perfect agreement. Therefore, the questionnaires appear to be reliable tools for assessing specific determinants of cycling to school. Furthermore, it was found that children overestimate their abilities to perform basic bicycle skills. This suggests that objectively measuring bicycle skills is preferred to child reported skills assessment

Galileo and Huygens on free fall : mathematical and methodological ifferences

In this essay, I will scrutinize the differences between Galileo's and Huygens's demonstrations of free fall, which can be found respectively in the Discorsi and the Horologium, from a mathematical, representational and methodological perspective. I argue that more can be learnt from such an analysis than the thesis that Huygens re-styled Galilean mechanics which is a communis opinio. I shall argue that the differences in their approach on free fall highlight a significantly different mathematical and methodological outlook

'Celeberrimus Atheismi patronus praecedentis saeculi': Petrus van Musschenbroek's anti-Spinozism unveiled

In this essay, I will bring several hitherto neglected sources, which pertain to Petrus van Musschenbroek’s (1692-1762) unpublished manuscripts, to the fore. The folios at hand show that Musschenbroek read and actively engaged with Spinoza’s (1632-1677) Ethica. More precisely, it will be shown that Musschenbroek held clear-cut anti-Spinozistic convictions
