El passat diumenge 14 de mar\u00e7 \u00e9s va celebrar el dia del n\u00famero Pi, commemorant la constant d\u2019Arqu\u00edmedes, que va ser un dels primers en fer una estimaci\u00f3 de \u03c0 de forma rigorosa.<\/p>\n
Aquest data, va ser escollida perqu\u00e8, \u00a0en format anglosax\u00f3, es representa com 3\/14, i coincideix amb les primeres xifres amb les que es representa el nombre \u03c0= 3.14\u2026<\/p>\n
Des de l\u2019any 2020, el dia del nombre Pi es considerat tamb\u00e9 com \u201cEl Dia Internacional de les Matem\u00e0tiques\u201d.<\/p>\n
Enguany va coincidir en cap de setmana, per\u00f2 els\/les alumnes de 1r i 2n d\u2019ESO vam realitzar diverses activitats relacionades amb la celebraci\u00f3, algunes de les quals es poden veure exposades al passad\u00eds de la primera planta.<\/p>\n
Els\/les alumnes de 1r d\u2019ESO vam dibuixar circumfer\u00e8ncies de diferents di\u00e0metres i\u00a0 despr\u00e9s vam calcular els primers d\u00edgits dels nombre pi, dividint la mesura del per\u00edmetre o longitud de la circumfer\u00e8ncia entre\u00a0 la mesura del seu di\u00e0metre. Els resultats que vam obtenir s\u2019aproximaven a 3\u20191.<\/p>\n
D\u2019 altra banda, els\/les alumnes de 2n d\u2019ESO van fer recerca de \u00a0poesies i pi-relats, que s\u00f3n poemes o microcontes<\/strong>\u00a0en els que <\/strong>\u00a0s\u2019amaga el n\u00famero Pi, \u00e9s a dir, el n\u00famero de lletres de cada paraula es correspon amb les xifres del n\u00famero \u03c0: 3,141592653589\u2026 la primera paraula t\u00e9 tres lletres, la segona una, la tercera quatre, la cinquena una, la sisena cinc\u2026 \u00a0Tamb\u00e9 van trobar acudits molt divertits sobre aquesta famosa constant. A m\u00e9s a m\u00e9s, van cercar informaci\u00f3 sobre els seus or\u00edgens i van descobrir diferents maneres de representar les seves infinites xifres decimals. Finalment,\u00a0 van elaborar cartells informatius parlant de la import\u00e0ncia de les matem\u00e0tiques en l\u2019actualitat, tant en el medi ambient, com en la\u00a0COVID-19, en el m\u00f3n digital… En definitiva unes \u201cMatem\u00e0tiques per a un m\u00f3n millor\u201d que \u00e9s el lema que s\u2019ha escollit per celebrar la diada matem\u00e0tica d\u2019enguany.<\/p>\n Marta Torres
