QUE SIGNIFIE HELIX EN ANGLAIS
Hélix
Une hélice est un type de courbe d'espace lisse, c'est-à-dire une courbe dans un espace tridimensionnel. Il a la propriété que la ligne tangente à n'importe quel point forme un angle constant avec une ligne fixe appelée l'axe. Des exemples d'hélices sont les ressorts hélicoïdaux et les mains courantes des escaliers en colimaçon. Une hélice "remplie" - par exemple, une rampe en spirale - s'appelle helicoïde. Les hélices sont importantes en biologie, car la molécule d'ADN est formée en deux hélices entrelacées, et de nombreuses protéines ont des sous-structures hélicoïdales, connues sous le nom d'hélices alpha. Le mot hélice provient du mot grec ἕλιξ, "tordu, courbé".
