Incerca\u021bi s\u0103 face\u021bi un mic experiment:<\/font><\/p>\n

C\u0103uta\u021bi o \u021beava lung\u0103, de genul celor pe care se fixau \u00eenainte de re<\/font>volu\u021bie antenele de TV. A\u0219eza\u021bi-o \u00een pozi\u021bie vertical\u0103.\"Clipboard01\"<\/a><\/font><\/p>\n

Ve\u021bi constata c\u0103, indiferent de greutatea acesteia, men\u021binerea \u00een pozi\u021bie vertical\u0103 a \u021bevii nu v\u0103 solicit\u0103 nici un efort, pute\u021bi s\u0103 o sus\u021bine\u021bi chiar dac\u0103 o propti\u021bi cu un singur deget.<\/font><\/p>\n

Acest lucru se datoreaz\u0103 faptului c\u0103 \u00eentreaga greutate a \u021bevii este orientat\u0103 vertical, spre baza \u021bevii, greutatea acesteia fiind sus\u021binut\u0103 \u00een \u00eentregime de sol.<\/font><\/p>\n

Dup\u0103 aceea, \u00eencerca\u021bi s\u0103 o \u00eenclina\u021bi \u00eencet sus\u021bin\u00e2nd-o \u00een continuare. <\/font><\/p>\n

Ve\u021bi constata c\u0103 pe m\u0103sur\u0103 ce \u021beava este mai \u00eenclinat\u0103 o sus\u021bine\u021bi tot mai greu, pentru c\u0103 centrul de greutate se mut\u0103 de-a lungul unei drepte care reprezinta proiec\u021bia \u021bevii pe orizontal\u0103 \u0219i bra\u021bul dumneavoastr\u0103 este nevoit s\u0103 sus\u021bin\u0103 o parte tot mai mare din greutatea \u021bevii. <\/font><\/p>\n

C\u00e2nd unghiul format \u00eentre \u021beav\u0103 \u0219i sol scade sub o anumit\u0103 valoare \u021beava nu mai poate fi sus\u021binut\u0103.<\/font><\/p>\n

Ceva asem\u0103n\u0103tor se \u00eent\u00e2mpla \u0219i \u00een cazul unei reac\u021bii \u00een lan\u021b, p\u00e2n\u0103 la un moment dat reac\u021bia poate fi controlat\u0103 folosindu-se un \u2018absorbant\u201d de neutroni, de exemplu grafitul, dar la un moment dat, dac\u0103 num\u0103rul de neutroni emi\u0219i dep\u0103\u0219e\u0219te o anumit\u0103 valoare reac\u021bia nu mai poate fi controlat\u0103.<\/font><\/p>\n

La un moment dat am citit un text scris de un ofi\u021ber de avia\u021bie, membru CADA, \u00een care se povestea c\u0103 \u00een perioada dintre 17 \u0219i 22 decembrie, la o unitate de cercetare a armatei s-a f\u0103cut un experiment asem\u0103n\u0103tor:<\/font><\/p>\n

Baz\u0103ndu-se pe experien\u021ba \u00eenregistrat\u0103 de-a lungul timpului \u00een alte \u021b\u0103ri, ofi\u021berii care au analizat datele referitoare la mi\u0219c\u0103rile de protest de la noi  au ajuns la concluzia c\u0103 dac\u0103 mi\u0219c\u0103rile de protest se amplific\u0103 timp de c\u00e2teva zile \u00eenseamn\u0103 c\u0103 protestatarii vor \u00eenvinge sistemul \u00eempotriv\u0103 c\u0103ruia protesteaz\u0103.<\/font><\/p>\n

Acesta a fost adev\u0103ratul motiv pentru care \u00een 22 decembrie organele de represiune au ales s\u0103 treac\u0103 de cealalt\u0103 parte a baricadei (la Timi\u0219oara motivul a fost altul), s\u0103 nu-\u0219i \u00eenchipuie nimeni c\u0103 cei care au fost ni\u0219te tic\u0103lo\u0219i p\u00e2n\u0103 \u00een urm\u0103 cu o zi au avut brusc o revela\u021bie divin\u0103 \u0219i au devenit sfin\u021bi peste noapte.<\/font><\/p>\n

Ast\u0103zi suntem \u00een 3 februarie.<\/font><\/p>\n

Mi\u0219c\u0103rile de protest se desf\u0103\u0219oar\u0103 de c\u00e2teva zile, amplific\u00e2ndu-se de la o zi la alta. Probabil \u00een weekend vom asista la un record \u00een privin\u021ba num\u0103rului de oameni ie\u0219i\u021bi \u00een strad\u0103, astfel c\u0103 p\u00e2na la momentul t0<\/sup> \u00een care greutatea \u021bevii nu va mai putea fi sus\u021binut\u0103 nu mai r\u0103m\u00e2n dec\u00e2t 2-3 zile, maxim o sapt\u0103m\u00e2n\u0103.<\/font><\/p>\n

De aceea urmatoarele zile vor fi deosebit de interesante, oare se va dovedi c\u0103 rom\u00e2nii sunt un popor care seam\u0103n\u0103 cu un blitz sovietic, \u00eencep str\u0103lucitor dar se descarc\u0103 repede, ajung\u0103nd astfel ca peste c\u00e2teva zile s\u0103 ne fi \u00eentors la vremurile \u00een care seniorul avea drept de via\u021b\u0103 \u0219i de moarte asupra supu\u0219ilor s\u0103i? <\/font><\/p>\n

Sau dimpotriv\u0103, mul\u021bi politicieni \u0219i sus\u021bin\u0103tori mai mult sau mai pu\u021bin interesa\u021bi ai acestora, inclusiv comentatori pe Facebook, vor fi nevoi\u021bi s\u0103 recunoasc\u0103 c\u0103<\/font><\/p>\n
