\u00ab\u00a0Un astrolabe pour l’hémisphère sud\u00a0\u00bb<\/strong> est une animation proposée par l’IREM de la Réunion pour la fête de la science. Un groupe de professeurs du lycée Édouard-Branly de Créteil, dont le noyau est composé de Gérard Delaforge<\/strong> (productique), Thierry Boucher<\/strong> (physique), Philippe Dutarte<\/strong> (mathématiques), ont réalisé un astrolabe pour l’hémisphère sud à la demande de Dominique Tournès<\/strong>, professeur à l’IUFM de la Réunion, spécialement pour la fête de la science 2007. Celle-ci aura lieu du 12 au 18 novembre à la Réunion, soit un mois plus tard qu’en métropole: le temps pour les visiteurs du nord de traverser l’océan en bateau en se guidant avec l’astrolabe. L’opération est fiancée par l’IREM de la Réunion<\/a><\/span> et Sciences Réunion<\/a><\/span>.<\/p>\n

Philippe Dutarte<\/strong> présente cette animation en exclusivité pour CultureMATH<\/em>: c’est ici<\/a><\/span>.<\/p>\n
