\u201eProbabilit\u0103\u021bile ca umanitatea s\u0103 mai tr\u0103iasc\u0103 \u00eenc\u0103 50 de ani sunt foarte mici\u201d, a declarat omul de \u0219tiin\u021b\u0103, potrivit publica\u021biei El Tiempo.<\/p>\n

Temerea lui principal\u0103 este un r\u0103zboi nuclear. \u00cen timpul R\u0103zboiului Rece, exper\u021bii evaluau riscul unui astfel de conflict la aproximativ 1% pe an.<\/p>\n

Gross estimeaz\u0103 c\u0103 probabilitatea s-a dublat \u00eentre timp, ajung\u00e2nd la aproape 2% anual. La acest ritm, orizontul de supravie\u021buire al omenirii ar cobor\u00ee la circa 35 de ani, potrivit calculului s\u0103u.<\/p>\n

Fizicianul invoc\u0103 num\u0103rul mare de puteri nucleare, nou\u0103 \u00een prezent, \u0219i pr\u0103bu\u0219irea marilor tratate de control al armamentului. El avertizeaz\u0103 \u0219i c\u0103 automatizarea armelor, inclusiv prin inteligen\u021b\u0103 artificial\u0103, ar putea duce la erori fatale f\u0103r\u0103 interven\u021bie uman\u0103.<\/p>\n

C\u00e2t mai are de tr\u0103it omenirea? R\u0103spunsul nelini\u0219titor al unui laureat Nobel<\/h2>\n

Americanul \u0219i-a petrecut mare parte din carier\u0103 studiind ce \u021bine materia unit\u0103. \u00cen ultimii ani, preocup\u0103rile sale publice s-au extins \u00eens\u0103 dincolo de fizica teoretic\u0103.<\/p>\n

Gross a vorbit despre riscurile legate de deciziile oamenilor, de tensiunile interna\u021bionale \u0219i de stabilitatea sistemelor globale. El aplic\u0103 no\u021biuni precum riscul, probabilitatea \u0219i comportamentul sistemelor complexe rela\u021biilor dintre marile puteri.<\/p>\n

Fizicianul a explicat c\u0103 fizica este un joc de explorare, \u00een care nimic nu e sigur. Teoreticienii pot uneori anticipa, dar natura r\u0103m\u00e2ne judec\u0103torul final, a spus el.<\/p>\n

David Gross s-a n\u0103scut \u00een Statele Unite \u00een 1941 \u0219i a lucrat la institu\u021bii academice precum Princeton. \u00cen anii 1970, a participat la cercet\u0103ri despre comportamentul quarcilor, particulele care formeaz\u0103 protonii \u0219i neutronii.<\/p>\n

\u00cempreun\u0103 cu Frank Wilczek \u0219i H. David Politzer, a descoperit a\u0219a-numita \u201elibertate asimptotic\u0103\u201d. Fenomenul arat\u0103 c\u0103 interac\u021biunea dintre quarci sl\u0103be\u0219te atunci c\u00e2nd ace\u0219tia se afl\u0103 la distan\u021be extrem de mici.<\/p>\n

Descoperirea a stat la baza cromodinamicii cuantice, teoria care descrie interac\u021biunea puternic\u0103 dintre quarci \u0219i gluoni. Pentru aceste contribu\u021bii, cei trei cercet\u0103tori au primit Premiul Nobel pentru Fizic\u0103 \u00een 2004.<\/p>\n

Dup\u0103 Nobel, Gross a continuat s\u0103 lucreze \u00een fizica teoretic\u0103. El a participat la dezbateri \u0219tiin\u021bifice despre teoria corzilor \u0219i despre c\u0103utarea unei explica\u021bii unitare pentru for\u021bele fundamentale ale naturii.<\/p>\n","protected":false},"excerpt":{"rendered":"
