Pourquoi ne pas avoir trac\u00e9 tout droit pour relier les c\u00f4tes canadiennes? La premi\u00e8re raison est toute naturelle: partant de Bretagne, les marins suivent les vents du nord les poussant vers les \u00eeles britanniques, puis l\u2019Islande, avant de \u00ab\u00a0retomber\u00a0\u00bb sur le Groenland puis l\u2019\u00eele de Terre Neuve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C\u2019est un chemin naturel qu\u2019ont du emprunter les p\u00eacheurs de morue avant Jacques Cartier, sans m\u00eame parler des vikings qui ont touch\u00e9 les premiers les rivages nord am\u00e9ricains d\u00e8s le d\u00e9but du XIeme si\u00e8cle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mais cette trajectoire courb\u00e9e est aussi un l\u00e9ger trompe l&#8217;\u0153il, d\u00fb \u00e0 la courbure de la terre.
