Rewriting Modernity
This article rereads Paul Virilio, drawing on the distinctionbetween topography and topology to argue a case for Virilio as a rewriter of modernity. Invoking Jean-François Lyotardâs notion of rewriting modernity as an unbroken process of accumulation founded on affective life in âRe-writing Modernityâ and âArgumentation and Presentation: The Foundation Crisis,â it enlists topology as a horizontal spatial structure that enables us to rethink space, time,and modernity outside the limits of the âsquared horizon,â where theâsquared horizonâ is viewed as a spatial and textual metaphor for framing perspectives on the past, present, and future. The analysis deconstructs the topography of the âsquared horizonâ as a relationality in an unfolding continuum, where spaces exist ontologically and where the immaterial forces of the dromospheric and the atmospheric generate a relational and historical connectedness
A Manifesto of Nodalism
This paper proposes the notion of Nodalism as a means describing contemporary culture and of understanding my own creative practice in electronic music composition. It draws on theories and ideas from Kirby, Bauman, Bourriaud, Deleuze, Guatarri, and Gochenour, to demonstrate how networks of ideas or connectionist neural models of cognitive behaviour can be used to contextualize, understand and become a creative tool for the creation of contemporary electronic music
Polymer and surface roughness effects on the drag crisis for falling spheres
8 pagesWe make time resolved velocity measurements of steel spheres in free fall through liquid using a continuous ultrasound technique. We explore two different ways to induce large changes in drag on the spheres: 1) a small quantity of viscoelastic polymer added to water and 2) altering the surface of the sphere. Low concentration polymer solutions and/or a pattern of grooves in the sphere surface induce an early drag crisis, which may reduce drag by more than 50 percent compared to smooth spheres in pure water. On the other hand, random surface roughness and/or high concentration polymer solutions reduce drag progressively and suppress the drag crisis. We also present a qualititative argument which ties the drag reduction observed in low concentration polymer solutions to the Weissenberg number and normal stress difference
