Preface: Sylvia Wynter's Agonistic Intimations

Sylvia Xin

Solid-state nanofluidic devices have proven to be ideal systems to elucidate the physics of nanoscale ion transport. When the device confinement approaches the Debye length of ions in the fluid, new phenomena occur such as surface-charge-dominated transport and ion-selectivity. Although these effects have been understood for simple monovalent systems, application-critical divalent systems have ...

Intimations of Infinity

The comments above (see below for who made them and when) represent one type of thinking about infinity. There are other types, as we will see, and they all create difficulties for students, philosophers and even mathematicians. The purpose of this article is to show how a particular theory about how people come to understand mathematics, APOS Theory, can be helpful in understanding the thinkin...

Yet though with years my body downward trend As trees beneath their fruit in autumn bend. Spite of my snowy hair and icy veins My head a cheerful temper still retains. Blake paints a bearable picture of old age and it is necessary to recognise that while the ageing process inevitably brings change, in the absence of disease normal people should retain understanding and mobility and can expect t...
