Le 14 juillet 2015, la sonde NASA New Horizons a, pour la première fois, survolé Pluton, sa lune Charon et leur quatre petits satellites. Elle a découvert un monde actif et spectaculaire, au cœur d'un système planétaire complexe et étonnant, révélateur de la richesse des objets « transneptuniens » qui gravitent aux confins du système solaire. Pour comprendre Pluton, nous devons inventer une nouvelle géophysique, totalement différente de ce que nous connaissons sur Terre.

Biological Networks Entropies: examples in neural, genetic and social networks

The networks used in biological applications at different scales (molecular, cellular and populational) are of different types, genetic, neuronal, and social, but they share the same dynamical concepts, the notion of intercation graph G(J) associated to their Jacobian matrix J, and also the concepts of frustrated nodes, positive or negative circuits of G(J), kinetic energy, entropy, attractors, structural stability, etc...are relevant and useful for studying the dynamics and the robustness of these systems.We will give some general results available for both continuous and discrete biologial networks and then, give some specific applications (a neural network involved in the memory evocation, ...

Opening Ceremony

 The theme of the Re(s)sources 2018 international conference is‘teachers interacting with resources’which will be discussed in seven plenary lectures, a plenary panel and four Working Groups. The conference is followed by a young researcher workshop structured under four sessions.  The Re(s)sources 2018 call for contributions concerned participation in the Working Groups, which constitute the essential place for presentation, discussion, and collective work on specific topics related to resources. Each proposal has been peer-reviewed (and subsequently revised), resulting in 70 accepted oral and 7 accepted poster contributions.Cérémonie d'ouvertureLe thème de la conférence internationale ...

Studying Teachers’ documentation work: emergence of a theoretical approach

The documentational approach to didactics is a recent theory –less than ten years old. In this conference I will look back at the process of development of this approach. I will recall the initial context, motivating the elaboration of a specific frame for studying teachers’ documentation work. Several kinds of evolutions will be emphasized: theoretical, methodological, but also evolutions of the questions studied in the research works referring to the documentational approach. I will conclude by evidencing the perspectives for future research and further evolutions.  Adler, J. (2000). Conceptualising resources as ...
