Durant aquesta setmana passada i en motiu del dia internacional del nombre Pi (14\/3)<\/strong>, hem celebrat a l’escola la setmana matem\u00e0tica. La proposta did\u00e0ctica gira al voltant de conceptes matem\u00e0tics que propicien i estimulen pensament matem\u00e0tic. Oferim a l’alumnat que pugui gaudir de diferents activitats i racons matem\u00e0tics amb un ventall ampli d’oferta matem\u00e0tica: Jocs de taula, Sudoku, rob\u00f2tica(bee-bots), tan-gram, reptes de construccions, instruccions, etc. Tamb\u00e9 es fan propostes art\u00edstiques relacionades amb el m\u00f3n matem\u00e0tic, can\u00e7ons i contes, tot un m\u00f3n!!!<\/p>\n

Aqu\u00ed van algunes curiositats del nombre Pi:<\/strong><\/p>\n

    \n
  1. Celebrar el dia Pi va ser una ocurr\u00e8ncia del f\u00edsic Larry Shaw, una proposta que va acabar guanyant tanta popularitat que en el 2009 la C\u00e0mera de Representants dels Estats Units va declarar oficialment el 14 de mar\u00e7 com a Dia Nacional de Pi.<\/li>\n
  2. No solament existeix el Dia de\u00a0Pi. Tamb\u00e9 al calendari podem trobar diversos dies d’Aproximaci\u00f3 al\u00a0Pi. Aquests se celebren el 22 de juliol, ja que la fracci\u00f3 resultant de 22\/7 d\u00f3na com a resultat 3,142857, un nombre molt proper al valor de\u00a0Pi; el 26 d’abril (o 25 d’abril, en anys de trasp\u00e0s), dia en qu\u00e8 la Terra completa dues unitats astron\u00f2miques de la seva \u00f2rbita anual (la longitud total de l’\u00f2rbita dividida entre la longitud recorreguda \u00e9s igual a\u00a0Pi); el 21 de desembre (20 de desembre, en anys de trasp\u00e0s), dia 355 de l’any, a les 01:13\u00a0PM, la fracci\u00f3 del qual coincideix amb el valor aproximat de 3,141592; i el 10 de novembre (o 9 de novembre, en any de trasp\u00e0s), dia n\u00famero 314 de l’any.<\/li>\n
  3. En 1706, el matem\u00e0tic angl\u00e8s William Jones va ser el primer a utilitzar el s\u00edmbol grec Pi (\u03c0) per denotar la relaci\u00f3 entre la circumfer\u00e8ncia i el seu di\u00e0metre.<\/li>\n
  4. Albert Einstein va n\u00e9ixer el 14 de mar\u00e7.<\/li>\n
  5. El matem\u00e0tic angl\u00e8s William\u00a0Shanks\u00a0va dedicar 20 anys a calcular 707 decimals de\u00a0Pi. En 1945 es va descobrir que havia com\u00e8s un error en el decimal 528 i a partir d’aquest nombre, tots els altres eren, \u00e9s clar, incorrectes.<\/li>\n
  6. En el 2002 el japon\u00e8s\u00a0Akira\u00a0Haraguchi\u00a0va trencar el r\u00e8cord mundial recitant els 83.431 d\u00edgits del nombre\u00a0Pi. El 3 d’octubre del 2006, a la 1:30 AM i despr\u00e9s de 16 hores i mitjana,\u00a0Haraguchi\u00a0va tornar a trencar el seu propi\u00a0r\u00e8cord\u00a0recitant 100.000 d\u00edgits del nombre\u00a0Pi, realitzant una parada cada dues hores de deu minuts per descansar.<\/li>\n
  7. L’\u00faltim\u00a0r\u00e8cord\u00a0sobre el c\u00e0lcul de\u00a0Pi\u00a0ho van aconseguir els inform\u00e0tics Alexander\u00a0Yee\u00a0i\u00a0Shigeru\u00a0Kondo, els qui han aconseguit calcular 12,1 bilions de decimals, sent l’\u00faltim decimal calculat un 5. Si escriv\u00edssim seguits els 12,1 bilions de decimals amb font Times\u00a0New\u00a0Roman de grand\u00e0ria 12, el paper necessari per apuntar-los tots donaria unes 60 voltes al nostre planeta Terra.<\/li>\n
  8. Si ens posem estrictes… en realitat\u00a0Pi\u00a0\u00e9s incalculable i dir que es correspon a 3,14 \u00e9s fer la vista molt grossa. En realitat\u00a0Pi\u00a0\u00e9s la relaci\u00f3 en la longitud d’una circumfer\u00e8ncia i el seu di\u00e0metre, la qual cosa significa que\u00a0Pi\u00a0\u00e9s irracional i etern.<\/li>\n<\/ol>\n

    A m\u00e9s a m\u00e9s, per finalitzar i tancar la setmana fem un repte com\u00fa on hi participa tot l’alumnat. Ja us explicarem!<\/p>\n
