Description
« Vous êtes invités à voir tourner la Terre », extrait d'une invitation à une démonstration scientifique de Léon Foucault (1819-68)
Un ornement de bureau fascinant inspiré du pendule de Foucault, le premier instrument à démontrer directement la rotation de la Terre lors d'une célèbre expérience réalisée en 1851 par le physicien français Léon Foucault (1819-68). Suspendez la bobine en fer et en acier au bras en plastique de 38cm et observez la pointe de la bobine inscrire progressivement des motifs géométriques dans le bac à sable ; les changements angulaires dans le mouvement de balancier sont créés par la rotation de la planète et se déplacent conformément aux mouvements prédits par la loi des sinus de Foucault. La démonstration publique de Foucault au Panthéon de Paris s'est avérée si populaire qu'elle a été reproduite par les musées depuis lors. Pour réaliser l'expérience vous-même, il suffit de remplir le bac peu profond de sable et d'insérer le bras, suspendezle globe et regardez la Terre tourner rien que pour vous.
