face="Verdana, Arial, Helvetica, sans-serif" size=2>En biologie contemporaine de
l'évolution et du développement, on appelle <I>plasticité</I> la capacité qu'ont
certaines structures de s'informer et se déformer tout en gardant leur unité et
leur cohérence. Cette capacité, équilibre dynamique entre robustesse et
fragilité, entre invariance et historicité, apparaît comme une des
caractéristiques les plus essentielles du vivant et, de manière plus générale,
de tout ce qui participe d'une évolution ; elle se trouve donc au foyer
d'interrogations tout à fait fondamentales. La physique théorique et
mathématique, quant à elle, croise le thème de la plasticité à l'occasion de
nombreux développements importants, comme ceux concernant les symétries et
brisures de symétries, les systèmes désordonnés, ou bien, récemment, la théorie
des paysages.</FONT>
<P><FONT face="Verdana, Arial, Helvetica, sans-serif" size=2>La dixième
rencontre « Physique et Interrogations Fondamentales » a comme
ambition de faire progresser la réflexion croisée des biologistes, des
physiciens, des mathématiciens, des scientifiques des sciences humaines et
sociales et des philosophes sur ce riche concept de plasticité.</FONT></P>
