D\u00e8s l&rsquo;Antiquit\u00e9, l&rsquo;Homme redoute que le ciel ne lui tombe sur la t\u00eate. Dans les diff\u00e9rentes mythologies de l&rsquo;\u00e9poque, la foudre est vue comme l&rsquo;expression de la col\u00e8re des Dieux. Or, il s&rsquo;agit tout simplement d&rsquo;un nuage qui se charge d\u2019\u00e9lectricit\u00e9 par le frottement de mol\u00e9cules et de particules, cr\u00e9ant un courant n\u00e9gatif. La charge du sol, positive, attire celle du nuage par l&rsquo;interm\u00e9diaire de l&rsquo;air conducteur. Ainsi se cr\u00e9ent les \u00e9clairs!<\/p>\n<p>Dans l&rsquo;eau, certaines esp\u00e8ces de poissons peuvent lib\u00e9rer des impulsions \u00e9lectriques. Les anguilles \u00e9lectriques, par exemples, peuvent lib\u00e9rer des secousses d&rsquo;une intensit\u00e9 \u00e9gale \u00e0 quatre fois le courant d&rsquo;une prise \u00e9lectrique. Une d\u00e9charge suffisante pour terrasser un alligator trop gourmand.<\/p>\n<p>Deux mille ans avant JC, les p\u00eacheurs \u00e9gyptiens d\u00e9couvrent que les d\u00e9charges des poissons-chats, pris dans leurs filets, provoquent l&rsquo;engourdissement. Plus tard, les Grecs puis les Romains apprivoisent ce ph\u00e9nom\u00e8ne \u00e9lectrique. Le poisson-torpille sera ainsi utilis\u00e9 pour soigner la goutte, l&rsquo;arthrite ou encore les migraines, comme celles de l&rsquo;illustre empereur romain Claude (41-54 ap. JC).<\/p>\n<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Partez \u00e0 la d\u00e9couverte de l&rsquo;histoire de l&rsquo;\u00e9lectricit\u00e9 \u00e0 travers un dessin anim\u00e9 cr\u00e9\u00e9 avec des enseignants suisses.
