Une planche qui flotte dans les airs : de quoi \u00e9veiller la curiosit\u00e9 ! Maintenu \u00e0 environ trois centim\u00e8tres du rail, le Surf Volant glisse sans frottement, gr\u00e2ce aux propri\u00e9t\u00e9s des mat\u00e9riaux supraconducteurs. Refroidis \u00e0 l\u2019azote liquide, ceux-ci interagissent avec le champ magn\u00e9tique du rail, permettant au surf de l\u00e9viter et de rester stable au-dessus de celui-ci.<\/p>\n

La d\u00e9monstration \u00e9tait anim\u00e9e par Alain Sacuto, professeur \u00e0 l\u2019Universit\u00e9 Paris Cit\u00e9, Alexandr Alkhin, ing\u00e9nieur de recherche \u00e0 l\u2019Universit\u00e9 Paris Cit\u00e9, Atossa Jaubert, m\u00e9diatrice scientifique chez Universcience, et Valentin Delmonte, m\u00e9diateur scientifique chez Universcience.<\/p>\n

Souvent associ\u00e9e au monde microscopique, la physique quantique est difficile \u00e0 se repr\u00e9senter. Pourtant, certains ph\u00e9nom\u00e8nes li\u00e9s au comportement collectif des particules, comme le magn\u00e9tisme et la supraconductivit\u00e9, ont des effets palpables et accessibles \u00e0 toutes et \u00e0 tous. Le Surf Volant en est une illustration concr\u00e8te : en observant la planche l\u00e9viter, les visiteurs ont pu d\u00e9couvrir les propri\u00e9t\u00e9s \u00e9tonnantes de la mati\u00e8re et les ph\u00e9nom\u00e8nes physiques qui rendent cette exp\u00e9rience possible.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
