Pas toujours facile de se repr\u00e9senter la taille d’un atome, de la mol\u00e9cule d’ADN, ou celle du Soleil… <\/p>\n\n\n\n

L’excellent site internet \u00ab\u00a0L’\u00e9chelle de l’Univers<\/a>\u00a0\u00bb propose de partir de la taille approximative moyenne de l’Homme, puis de zoomer jusqu’\u00e0 celle des constituants de l’atome (les quarks), ou de d\u00e9-zoomer jusqu’\u00e0 atteindre la taille de l’Univers. Il est ainsi possible d’avoir une id\u00e9e des dimensions de diff\u00e9rents \u00e9l\u00e9ments de notre Univers, de fa\u00e7on absolue mais aussi de mani\u00e8re relative, en les comparant les uns aux autres. <\/p>\n\n\n\n

On trouvera ainsi dans cette application diff\u00e9rentes cellules (globule blanc, bact\u00e9ries), leurs organites, des virus, de l’ADN sous diff\u00e9rentes formes, ainsi que diff\u00e9rents m\u00e9tazoaires (la plus grande araign\u00e9e marine du monde, la fourmi les acariens, en passant par le Tyrannosaure Rex) mais \u00e9galement des \u00e9l\u00e9ments des champs de la physique, de l’astronomie, ou plus anthropiques. <\/p>\n\n\n\n

Attrapez la barre de d\u00e9filement et explorez cette application \u00e0 toute vitesse !<\/p>\n\n\n\n

(Fonctionne mieux sur PC, en plein \u00e9cran ; Une application smartphone est \u00e9galement disponible)<\/em><\/p>\n\n\n\n
