\nCu toat\u0103 str\u0103lucirea sa matematic\u0103, cifrei zero i-a luat dou\u0103 milenii s\u0103 devin\u0103 o cifr\u0103 propriu \u2013zis\u0103, iar acest lucru s-a \u00eent\u00e2mplat \u00een India. Potrivit specialistului Alex Bellos, India a fost cadrul perfect: \u201eIdeea de nimic ce devine ceva este ad\u00e2nc \u00eenr\u0103d\u0103cinat\u0103 \u00een cultura lor. Dac\u0103 te g\u00e2nde\u015fti c\u0103 au o stare de spirit pentru <<a face nimic>> \u2013<<nirvana>>, de ce nu ar avea \u015fi un simbol pentru <<nimic>>?\u201d. Simbolul numit \u201eShunya\u201d este un cuv\u00e2nt folosit ast\u0103zi pentru a desemna at\u00e2t conceptul de \u201enimic\u201d, c\u00e2t \u015fi num\u0103rul \u201ezero\u201d.<\/p>\n
\nOdat\u0103 ce a c\u00e2\u015ftigat teren \u00een Asia de Sud, a cobor\u00e2t Orientul Mijlociu, a fost \u00eencoronat de oamenii de \u015ftiin\u0163\u0103 islamici \u015fi a devenit parte a sistemului numeric arab, pe care \u00eel folosim \u015fi ast\u0103zi. Unii istorici spun c\u0103 originile indiene ale cifrei nu sunt corecte \u015fi ar trebui s\u0103 o consider\u0103m a sistemului numeric indo-arabic. Iar dup\u0103 \u00eenceputurile sale spirituale \u015fi intelectuale, zero a a traversat Europa, la fel cum cre\u015ftinii au traversat islamul. Totu\u015fi, ideile arabilor \u00een matematic\u0103 au fost \u00eenconjurate mereu de scepticism \u015fi ne\u00eencredere. De exemplu, \u00een 1299 \u201ezero\u201d a fost interzis \u00een Floren\u0163a, odat\u0103 cu toat\u0103 numerologia arab\u0103, consider\u00e2ndu-se c\u0103 \u00eencurajeaz\u0103 frauda, dar a fost acceptat, \u00een cele din urm\u0103, abia \u00een secolul al XV-lea.<\/p>\n
\nF\u0103r\u0103 \u00eendoial\u0103, de-a lungul timpului \u201ezero\u201d a ajutat la desoperiri matematice, metode \u015ftiin\u0163ifice \u015fi tehnologice pe care le utiliz\u0103m ast\u0103zi. P\u00e2n\u0103 \u00een secolul al XVII-lea, zero ap\u0103rea triumf\u0103tor la baza coordonaelor Carteziene, un sistem folosit \u015fi ast\u0103zi, de la inginerie la grafic\u0103 pe calculator. \u00cen timpul Rena\u015fterii \u201ezero\u201d a cunoscut cea mai mare putere, dovad\u0103 fiind ast\u0103zi diviziunea la el \u00eensu\u015fi. <\/p>\n","protected":false},"excerpt":{"rendered":"
