Sommario/riassunto |
|
La pandémie de Covid-19 a bouleversé les Amériques qui étaient, à l’automne 2021, le continent le plus touché au monde. Pourquoi ? Rétrospectivement, le continent américain présente plusieurs vulnérabilités : des inégalités économiques abyssales, un travail informel très important, une grande ouverture économique et culturelle sur les autres continents qui impliquent des mouvements intenses, notamment de personnes, ou encore la présence au pouvoir de régimes populistes peu enclins à prendre des mesures draconiennes. Les conséquences de la pandémie sur les sociétés américaines sont, elles aussi, profondes, parce qu’elles réactivent des lignes de fractures anciennes ou parce qu’elles font émerger de nouvelles configurations politiques ou sociales. Analyser un phénomène alors qu’il est encore en train de se dérouler, sans le recul dont on peut disposer une fois qu’on en connaît toutes les conséquences, est un exercice périlleux, mais néanmoins indispensable et attendu, en période de crise, de la part des praticiens des sciences sociales. C’est à cet exercice que se sont risqués les auteurs des douze contributions de cet ouvrage. Celui-ci ne cherche pas à tracer un tableau exhaustif de la pandémie sur le continent américain, mais à montrer comment certaines situations ou certaines thématiques se sont trouvées affectées par une réalité qui a pris tout le monde à l’improviste. Cet exercice de sciences sociales « à chaud » propose des éclairages importants à l’heure où tous les pays du monde cherchent à évaluer comment et combien la pandémie les a transformés. |

Sommario/riassunto |
|
This book provides a brief but accessible introduction to a set of related, mathematical ideas that have proved useful in understanding the brain and behaviour. If you record the eye movements of a group of people watching a riverside scene then some will look at the river, some will look at the barge by the side of the river, some will look at the people on the bridge, and so on, but if a duck takes off then everybody will look at it. How come the brain is so adept at processing such biological objects? In this book it is shown that brains are especially suited to exploiting the geometric properties of such objects. Central to the geometric approach is the concept of a manifold, which extends the idea of a surface to many dimensions. The manifold can be |

specified by collections of n-dimensional data points or by the paths of a system through state space. Just as tangent planes can be used to analyse the local linear behaviour of points on a surface, so the extension to tangent spaces can be used to investigate the local linear behaviour of manifolds. The majority of the geometric techniques introduced are all about how to do things with tangent spaces. Examples of the geometric approach to neuroscience include the analysis of colour and spatial vision measurements and the control of eye and arm movements. Additional examples are used to extend the applications of the approach and to show that it leads to new techniques for investigating neural systems. An advantage of following a geometric approach is that it is often possible to illustrate the concepts visually and all the descriptions of the examples are complemented by comprehensively captioned diagrams. The book is intended for a reader with an interest in neuroscience who may have been introduced to calculus in the past but is not aware of the many insights obtained by a geometric approach to the brain. Appendices contain brief reviews of the required background knowledge in neuroscience and calculus. |
