    The Arrogant Eye and the French Prohibition of the Veil

    Evânia Reich presents the argument that the veil laws in France—the banning of the full-face coverings in public and the banning of the headscarf in public schools—are consistent with the emancipatory project of French Laïcité. According to this argument, the veils that Muslim women wear are symbols of their oppression, whereas French education seeks to liberate each individual and Laïcité serves as a bulwark against the creeping oppressive influence of religion. Unveiling Muslim women, then, is an act of emancipation. In this essay, I argue that the view of French secularism as an emancipatory project to free women of the oppressive mechanism of the veil is an example of what Marilyn Frye calls the “arrogant eye.” In this essay, I offer an alternative approach on the veil following Frye’s notion of the “loving eye.

    Helping Students Master Concepts in Mechanics by Graphing with Spreadsheets

    Get PDF
    An example of a curricular activity to help students master concepts in mechanics is presented. Students measure positions and times of movements using calculators, and construct graphs using spreadsheets. Students learn to connect concepts in mechanics and reinforce them following a spiral approach of increasing complexity. Comments from students about the activity are also presented

    Mean field theory of assortative networks of phase oscillators

    Full text link
    Employing the Kuramoto model as an illustrative example, we show how the use of the mean field approximation can be applied to large networks of phase oscillators with assortativity. We then use the ansatz of Ott and Antonsen [Chaos 19, 037113 (2008)] to reduce the mean field kinetic equations to a system of ordinary differential equations. The resulting formulation is illustrated by application to a network Kuramoto problem with degree assortativity and correlation between the node degrees and the natural oscillation frequencies. Good agreement is found between the solutions of the reduced set of ordinary differential equations obtained from our theory and full simulations of the system. These results highlight the ability of our method to capture all the phase transitions (bifurcations) and system attractors. One interesting result is that degree assortativity can induce transitions from a steady macroscopic state to a temporally oscillating macroscopic state through both (presumed) Hopf and SNIPER (saddle-node, infinite period) bifurcations. Possible use of these techniques to a broad class of phase oscillator network problems is discussed.Comment: 8 pages, 7 figure
