Le 19 janvier dernier, les \u00e9l\u00e8ves des cord\u00e9es de la r\u00e9ussite se sont rendus \u00e0 la MISS de l’Universit\u00e9 Paris Saclay pour assister \u00e0 un atelier pratique qui m\u00eale physique et r\u00e9flexion autour du th\u00e8me \u00ab\u00a0Bulles et Mousses\u00a0\u00bb. En effet, les bulles et les mousses sont pr\u00e9sentes partout dans notre quotidien : en faisant la vaisselle, sous la douche, en se servant un verre de boisson gazeuse, dans la mousse au chocolat \u2026 Mais qu\u2019est-ce qu\u2019une bulle ? Qu\u2019est-ce qu\u2019une mousse ? Comment passer de l\u2019une \u00e0 l\u2019autre ? Une bulle peut-elle \u00eatre carr\u00e9e ? Les mousses ont-elles des propri\u00e9t\u00e9s \u00e9tonnantes, quels sont les points communs (ou pas) \u00e0 toutes les mousses ? Pourquoi les \u00e9tudier ?<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Apr\u00e8s un \u00e9change sur le parcours des deux doctorants en Physique, les \u00e9l\u00e8ves ont, dans un \u00a0premier temps, \u00e9tudi\u00e9 la constitution physique et chimique d\u2019une mousse, qui n\u2019est ni un liquide, ni un solide, ni un gaz. Ensuite, ils ont fait le lien entre les composantes \u00e9l\u00e9mentaires de la mousse (le film ou la bulle) et la mousse elle-m\u00eame. Il leur fallait trouver, par une suite de mod\u00e9lisations math\u00e9matiques, hypoth\u00e8ses et exp\u00e9riences, les lois physiques qui gouvernent l\u2019agencement des bulles dans une mousse. Enfin, ils ont d\u00e9montr\u00e9 comment ces lois physiques expliquent le comportement global d\u2019une mousse, entre \u00e9lasticit\u00e9 et plasticit\u00e9.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
