Ubani owasungula isibani sikagesi, futhi ubani owethulwa ekuphileni kwethu?

Namuhla ukuphila kwethu induduzo kuqinisekiswa ngenxa yobuningi imishini yezobuchwepheshe kanye ezihlukahlukene izinto zasendlini, ngaphandle okuyinto thina kakade kunzima ukuphatha. Sithatha kubo kuzinga enganakile, ngaphandle kokucabanga mayelana nokuthi bakuphatha kanjani ukusebenza, owayeneminyaka umsunguli yabo. Man ngokwemvelo njalo ukulwela ngaphezulu, ukuthi unezinto wokuvelela ehlelekile enqoba zonke nobunzima. Izibonelo ukuthi abantu akhohlwe izinkinga, baphikisana phambili ngokwanele.

Nokho, akufanele nanini sikhohlwe ngomlando wakhe, ikakhulu njengoba baningi izibonelo ukuthi ingahle ibe lusizo manje. Kwakukhona imisebenzi okuhluke kakhulu, kubonakala elula kakhudlwana futhi aphansi, kodwa ake ucabange ukube kwakungeyona ezejwayelekile light isibani, sengathi sasihlala khona manje? Cishe besingeke cabanga ubuchwepheshe besimanje, indiza emkhathini futhi ama-computer anamandla, futhi namanje bezama ukumisa ukuphila kwakho siqu uma ukhohlwa ubani owasungula isibani sikagesi.

Thina zijwayele attribute kokusungulwa ukuze abantu abathile, nakuba ngezinye izikhathi umphumela umzamo ngokubambisana inani elikhulu labantu, kodwa, isibonelo, owasungula isibani sikagesi, okuyinto manje ngazo zonke endlini?

Khanyisa kuwo wonke indlu

Kumele baqonde ukuthi ngaphandle ukukhanya ukuthi abantu abakwazi ukuphila, ngakho konke okusemandleni akhe ukuze beveza okuthile ukuze azenze zikhanye emizini yabo.

Endulo, wasebenzisa izimbiza yebumba egcwaliswe amafutha omnqumo yefilakisi ukotini. Kamuva iCaspian coast esetshenziswa izibani ezifanayo, kuphela esetshenziswa njengoba uwoyela nophethiloli. Phela, lo wokuqala wax amakhandlela avele kuphela eNkathini Ephakathi futhi zazibhekwa njengokuphela okusungulile ngokwanele kubalulekile ngesikhathi sako.

Kamuva, ukuthuthukiswa isayensi, ososayensi abaningi baye bazikhandla ukuxazulula le nkinga. Omunye wabo kwakungu-uLeonardo da Vinci owakhuphula eminingi yesayensi. Yena, futhi, kungaba ngokwengxenye kubhekwe njengento labo yasungulwa ukukhanya isibani kuqala. Nakuba kwaba bekhanyise isiketekete, wavele elicwengisiswe imibono ekhona. Kodwa inkinga azishintshile - i ilangabi evulekile eduze umthamo uphethiloli, eqinisweni, lokho niyakwenza nge Molotov Cocktails.

isibani

Njengoba sekushiwo ngenhla, isibani okusungulile ukukhanya - kungcono inqubo eside umsebenzi. Ekhulwini le-19 kufika sibonelo wokuqala ukukhanyisa kudivayisi evikelekile. Kwaba Russian unjiniyela kagesi kanye nososayensi Pavel Nikolaevich Yablochkov. It Yablochkov - lowo owasungula isibani sikagesi. Futhi credit wakhe kanye ikhandlela wokuqala kagesi. indlela yakhe saba nemiphumela ethile engathandeki eziningi, okokuqala kunakho konke, i engazinzile ukukhanya okukhipha nempilo ongaphakeme. Kodwa, noma kunjalo, yayisetshenziswa sibaningi ukukhanyisa emgwaqweni, kanye izinto ezibaluleke Russia: yeshashalazi, izitolo, izikwele emaphakathi, njll

Nokho, uzokwenza kufanele kuphawulwe ukuthi umbuzo othi obani owasungula isibani sikagesi, akunakwenzeka ukuba igama igama elilodwa kuphela.

Ekugcineni wathola ukwakheka kwesokudla carbon intambo, esangenza isibane sivuthe amahora ambalwa. Ingase futhi kwenziwe isibaluli nabasunguli isibani, nakuba ayisekho basebenzela ekuthuthukiseni, ngokuhlanganisa ososayensi ezahlukene ucwaningo kakade.
