Nhoroondo remakore rechi20 - paraiitwa kuchinja kukuru

Nhoroondo remakore rechi20 kunoratidzwa pamwero mukuru kuchinja munyaya zvose zvoupenyu hwevanhu: zvesayenzi, tsika, zvoupfumi, zvematongerwo enyika.

Chokutanga, zvinofanira kucherechedzwa munhu kwakawedzerwa zvinowanikwa nesayenzi mumunda wefizikisi, kemisitiri uye zvipenyu. Kana remakore rechi19, bhuku ruzivo kwesayenzi nekaviri mumakore 50, nhoroondo remakore rechi20 akashamiswa ne kudaro nemhaka mumakore 5 chete.

Kugadzirwa of hwemvura injini, izvo zvakaita kuti pave njanji chokufambisa, uye redhiyo kwakagonesa masayendisiti kukurukurirana kakawanda nemumwe uye kugoverana zvakawanwa dzavo. Mumwe kubudirira, kunyange kana zvishomanana, zvakasimbisa imwe mberi itsva nesayenzi.

Pakuonekwa Semiconductor akabvumira kudzora Magetsi, zvichiguma transistor.

Kuwanikwa kuvapo neutrons zvakasimbisa kukura kwesimba zvenyukireya, paiva Nyuturoni bhomba.

Kuwanikwa sechivako DNA zvakakonzera chidzoke imwe sainzi itsva - magene mapurani. Izvi zvaiita kuti clone mhuka.

Nhoroondo XX remakore kwakaratidza kuti aval ose zvinowanikwa nesayenzi akanga zvakawanda pamusoro pemafungiro pokumuka mabhora ose mabasa evanhu. Paiva nemotokari, pafoni, TV, kombiyuta, serura, Indaneti. Industrial kugadzirwa uye kurima vave vakagadzirira pamwe yepamusoro zvokushandisa, izvo yekudyidzana zvakawedzera negoho basa, uye nokudaro bhuku kugadzirwa.

Somugumisiro, paiva achikwakuka hombe musayenzi uye michina mberi. Zvino musika upfumi, ndiro maitire zvose capitalist kunyika, hauna kurongwa, kazhinji dzakabudirira paiva overproduction kuti mutengi nhumbi. zvigadzirwa zvose zvinoda yokutengesa, kutamburira misika kwave dzinotyisa. Hazvishamisi kuti nhoroondo remakore rechi20 panguva kuguma aizivikanwa mutsara nematambudziko emari kuti aval aburukira pamusoro pemarudzi mazhinji. Kushaya misika kumanikidzwa vagadziri kuvhara mafekitari, izvo zvakaita kuti pave nokuwedzera mabasa.

Nhoroondo remakore rechi20 vakapa vanhu mutsva munzanga inotungamirwa - ari Socialist - inova yakasiyana nemamwe idzodzo, kupfuura zvose, rudzi varidzi nzira inoshandiswa, Kuwanikwa vakaronga upfumi, kushaya kudzvinyirirwa womunhu mumwe nomumwe , etc. Pashure peHondo Yenyika II nhamba mugovanisi vaifarira nyika yakura, uye. pakati siyana idzodzo mbiri tichingotarisira kuenda nharo, kana kuti vanonzi "hondo inotonhora". Pakupera kwezana remakore ari mugovanisi hurongwa vasingagoni kumira kwoutsinye nomuedzo chokwadi.

Remakore rechimakumi maviri yakazadzwa anenge vaingogara hondo nokumukirana.

Next kuti mberi chinoshamisa kucherechedza kuti munhoroondo yenyika, zana remakore rechi20 aizivikanwa zvinetso. Izvi anonyanya:

- njodzi renyukireya;

- zvinetso zvemhoteredzo, kupfuura zvose - nezvakatipoteredza kusvibiswa uye mvura chishoma;

- the chidzoke uye kupararira kwezvirwere zvitsva ngozi - zvinodhaka uye AIDS;

- dzinongoitika dzoga uye nevamwe.

Yakawedzerwa kukura zvesainzi anofuridzira isu somunhu tariro itsva (eg. Kufambira mberi mune zvokurapa), uye zvinonetsa zvitsva.
