Umlando wekhulu lama-20 - inkathi yezinguquko ezinkulu

Umlando wekhulu lama-20 ubhekene nezinguquko ezinkulu kuzo zonke izigaba zokuphila komuntu: kwisayensi, emasiko, ezomnotho, ezombusazwe.

Okokuqala, kufanele kuqashelwe ukuxhuma okukhulu kwezinto ezitholwa yisayensi emkhakheni we-physics, chemistry kanye ne-biology. Uma ekhulwini le-19 ivolumu yolwazi lwesayensi ephindwe kabili eminyakeni engama-50, umlando wekhulu lama-20 wamangala ngaleyo ndlela eminyakeni emihlanu nje kuphela.

Ukusungulwa kwe- injini yesitimu, okwaholela ekuthuthukiseni ukuthutha izitimela, futhi umsakazo wanika ososayensi ithuba lokuxhumana njalo futhi bahlanganyele ngokutholakala kwabo. Ukuphumelela ngalunye, kungakhathaliseki ukuthi kuyingqayizivele, kunikeze amandla ekuthuthukiseni okusha kwesayense.

Ukuvela kwe-semiconductors kuvunyelwe ukulawula umbane kagesi, okwaholela ekubukeni kwezinto ezihamba phambili.

Ukutholakala kokutholakala kwe-neutron kwabangela ukuthuthukiswa kwamandla enyukliya, kwavela ibhomu le- neutron.

Ukutholakala kwesakhiwo se-DNA kwabangela ukuvela kwesayensi entsha yezakhi zofuzo. Futhi lokhu kwenza kube lula ukuhlanganisa izilwane.

Umlando wekhulu lama-20 wabonisa ukuthi ukuvuthwa kokutholakala kwesayensi kwaba nethonya elikhulu ekuthuthukiseni zonke izigaba zomsebenzi wesintu. Kwakukhona imoto, ifoni, i-TV, ikhompyutha, iselula, i-Intanethi. Ukukhiqizwa kwezezimboni kanye nezolimo kwakhiwe imishini ephakeme kakhulu, okwakwandisa kakhulu ukukhiqizwa komsebenzi, ngakho-ke, umkhiqizo wemikhiqizo.

Ngenxa yalokho, kwaba nenqwaba enkulu yenqubekela phambili yesayensi nezobuchwepheshe. Futhi njengoba umnotho wemakethe, ovamile kuwo wonke amazwe ase-capitalist, akuyona into ehleliwe, emazweni amaningi athuthukile kuye kwavela ukukhiqizwa ngokweqile kwezimpahla zabathengi. Zonke izimpahla zidinga ukumaketha, umzabalazo wezimakethe wawuyingozi. Akumangalisi neze ukuthi umlando wekhulu lama-20 ekupheleni kwawo wabonakala ngochungechunge lwezinkinga zomnotho ezithinta amazwe amaningi anesiphepho. Ukuntuleka kwezimakethe kwaphoqeleka abathengisi ukuba bakhiqize amafemu nezitshalo ezivaliwe, okwaholela ekwandeni kokungasebenzi.

Umlando wekhulu lama-20 wanikeza abantu isakhiwo esisha sezenhlalakahle - isazi sezenhlalo-esasihluke ngokuphawulekayo kwezinye izihlobo, okokuqala, ngendlela yobunikazi bezinto zokukhiqiza, ukutholakala komnotho ohleliwe, ukungabi nokuxhashazwa komuntu kumuntu , njll. Ngemuva kweMpi Yezwe Yesibili, inani lamazwe anama-socialist orientation landa, futhi Phakathi kwalezi zinhlobo ezimbili ezahlukene kwakukhona ukulwa njalo, noma okuthiwa "impi ebandayo". Ekupheleni kwekhulu leminyaka, isimiso sezenhlalakahle asizange sibhekane nokuvivinya okunzima kweqiniso.

Ikhulu leminyaka lama-20 lagcwala izimpi nokuguqulwa okungapheli.

Kanye nezimo eziqhubekayo, kufanele kuqashelwe ukuthi umlando wezwe, ngekhulu lama-20, wabonisa izinkinga eziningi. Lokhu ngokuyinhloko:

- Ingozi yokusetshenziswa kwamandla e-athomu;

- izinkinga zemvelo, okokuqala - ukungcola kwemvelo nokuntuleka kwamanzi;

- ukuvela nokusabalalisa izifo ezintsha eziyingozi - ukulutha izidakamizwa kanye ne-AIDS;

- izinhlekelele zemvelo, njll.

Ukuthuthukiswa okujulile kwesayensi nobuchwepheshe kusigqugquzela ngamathemba amasha (isib. Intuthuko emithi) kanye nokwesaba okusha.
