D\u0102 OARE DUMNEZEU CU ZARUL ? \u2013 NOUA MATEMATIC\u0102 A HAOSULUI, de Ian Stewart, Editura Humanitas, 2015\u2026<\/p>\n

Ian Nicholas Stewart<\/strong>(n. 1945), membru al Societ\u0103\u021bii regale din Marea Britanie<\/em>, profesor la Universitatea din Warwrick<\/em> \u0219i autor a peste 170 de articole \u0219tiin\u021bifice, este unul dintre matematicienii care s-au adresat constant publicului larg, fiind r\u0103spl\u0103tit cu Medalia Faraday<\/em> \u0219i cu Medalia de Aur a Institutului de Matematic\u0103 <\/em>pentru cele peste dou\u0103zeci de c\u0103r\u021bi de popularizare a \u0219tiin\u021bei, \u00een principal matematic\u0103 \u0219i teoria catastrofei. Dintre lucr\u0103rile lui Ian Stewart, la Editura Humanitas au ap\u0103rut Doar \u0219ase numere, De ce frumuse\u021bea este adev\u0103rul ? <\/em>\u0219i \u00cembl\u00e2nzirea infinitului<\/em>. A predat la universit\u0103\u021bi din Germania , Noua Zeeland\u0103 \u0219i Statele Unite.<\/p>\n

D\u0102 OARE DUMNEZEU CU ZARUL ? \u2013 NOUA MATEMATIC\u0102 A HAOSULUI a ap\u0103rut \u00een 1989. \u00cen Prefa\u021ba la edi\u021bia a doua<\/em>, ap\u0103rut\u0103 \u00een 1997, autorul \u00eencearc\u0103 s\u0103 explice despre ce este vorba \u00een aceast\u0103 lucrare: \u201eHaosul\u201d nu e doar un cuv\u00e2nt la mod\u0103 pentru \u201daleator\u201d. \u00cen sensul\u00a0 care predomin\u0103 ast\u0103zi \u00een \u0219tiin\u021b\u0103, e un concept cu totul nou \u0219i diferit. Haosul apare atunci c\u00e2nd un sistem determinist (adic\u0103 nealeator) se comport\u0103 \u00eentr-o manier\u0103 aparent aleatorie. Poate suna paradoxal, dar \u201eaparent\u201d ascunde multe dificult\u0103\u021bi. Marea descoperire a ultimului deceniu este c\u0103 haosul este la fel de des \u00eent\u00e2lnit \u00een tipurile tradi\u021bionale de comportament regulat precum st\u0103rile sta\u021bionare sau ciclurile periodice. Privind \u00een urm\u0103, nu g\u0103sim nimic cu adev\u0103rat surprinz\u0103tor legat de haos. Din perspectiv\u0103 actual\u0103, e u\u0219or de \u00een\u021beles cum apare haosul \u0219i de ce e frecvent \u00eent\u00e2lnit. \u0218i totu\u0219i, mult\u0103 lume, printre care \u0219i oameni de \u0219tiin\u021b\u0103, vorbe\u0219te despre haos ca despre ceva straniu \u0219i exotic. \u00cemi cer scuze, nu este cazul. Haosul este la fel de comun precum ciclurile periodice.[\u2026]<\/p>\n

D\u0102 OARE DUMNEZEU CU ZARUL ? urm\u0103re\u0219te dou\u0103 scopuri. Unul este acela de a explica no\u021biunea matematic\u0103 de haos \u0219i de a ar\u0103ta de ce este deopotriv\u0103 natural\u0103 \u0219i inevitabil\u0103. Cel\u0103lalt scop e s\u0103 r\u0103spund\u0103 la \u00eentrebarea: apare haosul \u00een lumea real\u0103? Pentru ca aceast\u0103 \u00eentrebare s\u0103 aib\u0103 sens, ea trebuie reformulat\u0103. Nici un fel de matematic\u0103 nu apare<\/em> \u00een lumea real\u0103. Ceea ce face matematica este s\u0103 modeleze lumea real\u0103 \u00eentr-o manier\u0103 util\u0103. Geometria cercului ne ajut\u0103 s\u0103 \u00een\u021belegem de ce ro\u021bile ruleaz\u0103 lin, dar nu vei g\u0103si un cerc matematic veritabil \u00eentr-o ma\u0219in\u0103. Po\u021bi g\u0103si dou\u0103 oi, dou\u0103 mere sau dou\u0103 rafturi \u00een lumea real\u0103, dar nu vei \u00eent\u00e2lni num\u0103rul doi ca atare. A\u0219adar, \u00eentrebarea ar trebui s\u0103 fie: \u201eNo\u021biunea matematic\u0103 de haos modeleaz\u0103 oare lumea real\u0103 \u00eentr-o manier\u0103 util\u0103 ? Ne ajut\u0103 ea s\u0103 \u00een\u021belegem ceva din lucrurile pe care le vedem ?\u201d(p.5-7)<\/p>\n

Dar autorul avertizeaz\u0103: \u201eNu \u00eencerc s\u0103 v\u0103 v\u00e2nd<\/em> haosul. Nu sunt profetul unei noi religii \u00een c\u0103utare de adep\u021bi. Departe de mine g\u00e2ndul de a ob\u021bine credin\u021ba<\/em> voastr\u0103. Ce \u00eencerc s\u0103 fac este s\u0103 v\u0103 prezint, c\u00e2t mai accesibil cu putin\u021b\u0103, informa\u021bia de care ave\u021bi nevoie pentru a v\u0103 face o idee despre realiz\u0103rile haosului din prezent \u0219i poten\u021bialul lui \u00een viitor. M-am str\u0103duit s\u0103 v\u0103 previn de fiecare dat\u0103 c\u00e2nd m\u0103 lansez \u00een specula\u021bii. \u00cen rest, prezint idei sau rezultate publicate \u00een literatura serioas\u0103 \u0219tiin\u021bific\u0103 \u0219i matematic\u0103. Ceea ce nu \u00eenseamn\u0103 neap\u0103rat c\u0103 ar fi corecte, ci doar c\u0103 sunt respectabile\u2026\u201d(p.10)<\/p>\n

Am \u021binut s\u0103 pun aici aceast\u0103 avertizare a autorului, fiindc\u0103 subiectul este tentant pentru a fi extrapolat \u00een domeniul teologiei \u0219i, unii chiar s-au jucat cu asta, f\u0103r\u0103 \u00eens\u0103 a avertiza, a\u0219a cum face Ian Stewart, c\u0103 au intrat \u00eentr-un joc speculativ\u2026<\/p>\n

Nu m\u0103 pricep la matematic\u0103, dar autorul acestei c\u0103r\u021bi \u0219tie s\u0103 scrie pentru profani. Din c\u00e2nd \u00een c\u00e2nd \u00eemi place s\u0103 fac incursiuni \u00een teritorii pe care nu le cunosc, m\u0103car pentru a deveni con\u0219tient c\u0103 acele teritorii exist\u0103\u2026Teoria haosului sun\u0103 incitant dac\u0103 m\u0103 g\u00e2ndesc la haosul ini\u021bial amintit \u00een Genesa. De aici \u00eencolo, \u00eens\u0103, voi p\u0103\u0219i cu mare aten\u021bie, ca s\u0103 fiu sigur c\u0103: \u201eEl nu va \u00eeng\u0103dui s\u0103 \u021bi se clatine piciorul\u2026\u201d(Psalmi 121,2)\u2026<\/p>\n
