A Cicle superior fem tallers de pl\u00e0stica! I hem fet un zootrop!<\/p>\n

El zootrop del grec ” roda de la vida”, (1834) va ser inventat pel\u00a0 matem\u00e0tic William George Horner a partir del fenaquistoscopi\u00a0 que \u00e9s el seu antecessor mes directe. \u00c9s un giny que crea la il\u00b7lusi\u00f3 del moviment a partir del fenomen de la persist\u00e8ncia de la visi\u00f3 de tal manera que les imatges que veiem tenen un perman\u00e8ncia a la nostra retina d\u2019una d\u00e8cima de segon. Aix\u00ed si es projecten 24 imatges per segon tenim la sensaci\u00f3 que veiem imatges en moviment.<\/p>\n

El zo\u00f2trop es b\u00e0sicament un\u00a0 tambor circular amb unes petites ranures\u00a0 distribu\u00efdes de forma homog\u00e8nia. A la seva part superior, just a sota de les ranures, per la part interior,\u00a0 s\u2019hi col\u00b7loca una\u00a0 tira d\u2019imatges que representen la descomposici\u00f3 d\u2019un moviment c\u00edclic.\u00a0 En girar el tambor, si es mira trav\u00e9s d\u2019una de les ranures, es t\u00e9 la il\u00b7lusi\u00f3 del moviment.<\/p>\n

\u00c9s una joguina \u00f2ptica d\u2019una relativa dificultat que es pot treballar a partir del del cicle superior de prim\u00e0ria. Us proposem una\u00a0guia<\/a>\u00a0i un v\u00eddeo que us permetran construir dos models diferents.<\/p>\n","protected":false},"excerpt":{"rendered":"
