Ngaba ucinga ukuba yonke into ebomini iphinda iphinda iphinde iphinde iphinde ibuye Kodwa oku akunjalo. Ngokomzekelo, sinokwenza iziganeko ezininzi ezenzeka kanye kuphela kwimbali. Ndikholelwe, ngokwenene bahlukile kwaye banomdla.
Ehlabathini kukho izinto ezininzi ezinomdla kwaye ezingavamile, kodwa ukuba ezinye iimeko zihlala ziphindaphinda, ngoko imbali iyayazi iimeko ezininzi kude kube ngoku ziye zenzeka kanye kuphela. Masifunde malunga neendaba ezicacileyo nezikhumbulekayo.
1. Ukunqoba kwincinci emnyama
Kwiminyaka yokugubha kwe-epidemic ye-smallpox, abantu abayizigidi ezi-2 bafa minyaka yonke, kwaye abo basinda bahlala bengafihli. Iingcali zenzululwazi ziye zasebenzela ukonyango kwesi sifo esibi ngaphezu kweminyaka eyi-10. Ngokweenkcukacha ezikhoyo, umcimbi wokugqibela we-smallpox wabhalwa ngo-1978, kwaye unyaka olandelayo wachazwa ngokusemthethweni ukuba eso sifo sichithwe. I-Blackpox yodwa isifo esiye sakwazi ukujamelana nayo kanye kunye.
2. Ubhubhane lokuhleka
Okumangalisa kukuba, ngo-1962 inkohlakalo yokuxinwa yabhalwa, eyenzeka eTanganyika (eyiTanzania). Ingqungquthela engaqhelekanga yaqala ngoJanuwari 30, xa abafundi abathathu besikolo samaKristu baqala ukuhleka ngokungalawulekiyo. Oku kwafunyanwa ngabanye abafundi, ootitshala nabanye abasebenzi, okwenze ukuba isikolo sivale ixesha elithile. I-Hysteria yasasazeka kwezinye iindawo, ngoko, ubhubhane luthatha abantu abangaphezu kwe-1 lamawaka kwaye lwahlala iinyanga ezili-18. Kungcono ukuhleka endaweni yesifo sengculazi minyaka yonke. Ngendlela, izazinzulu zikholelwa ukuba i-hysteria yayichukunyiswa yimimiselo yoqeqesho oluqinileyo, kwaye abantwana banciphisa uxinzelelo ngokuhleka.
3. Izaqhwithi ezonakalisayo
KwiNyakatho yeAtlantiki, iziphepho neziphepho zibhalwa rhoqo. Izibalo zibonisa ukuba ngokuqhelekileyo, abemi beemimandla bafumana iziphepho ezili-12 kunye neziphepho ezili-6 ngonyaka. Ukususela ngowe-1974, izivunguvungu zaqala ukubonakala kwi-Atlantic yaseMzantsi, kodwa oku kwakunqabile kakhulu. Ngo-2004, ecaleni kweNxweme yaseBrazil, iSiphepho iKatarina sagqitha, esabangela ukubhujiswa okukhulu. Kukholelwa ukuba nguyena kuphela umphekula oqoshwe kwintsimi ye-Atlantic.
4. Ukuhamba kweShefu
Into eyingqiqo kwaye engaqondakaliyo yenzeka ngo-Agasti 1915 eTurkey. I-Regiment yaseBrithani yeNorfolk yathatha inxaxheba kwimikhosi yemikhosi kwaye yenza inzuliso kwidolophana yaseAnafart. Ngokwababoni bokuzibonela, amajoni ayezungezwe ifu lobunzima obunzima, obuvela ngaphandle bebukeka njengesonka sesonka. Okuthakazelisayo, ukuma kwayo akuzange kutshintshe nangenxa yokuphelelwa umoya. Emva kokuba ilifu lidlulile, i-267 yegesi yanyamalala, kwaye akukho mntu wambona. Xa iTurkey yahlulwa iminyaka emithathu kamva, iBrithani yafuna ukubuya kwamabanjwa ale nkampani, kodwa iqela elilahlekileyo lathi alizange balwe nala majoni, ngokukodwa ekubeni abazange bathabathe entolongweni. Apho abantu bebalala khona, ihlala ingummangaliso.
Ukuphonononga kweeplanethi
Kuqhelekile ukuqwalasela u-Uranus no-Neptune njengeeplanethi zeqho. Oososayensi baqale bathumela i-Spacecraft Traveler 2 ekufundeni kwabo ngo-1977. Uranus wafikeleleka ngo-1986, kunye ne-Neptune - kwiminyaka emithathu. Ngombulelo uphando, kwakunokwenzeka ukuba u-Uranus ubandakanya i-85% ye-hydrogen kunye ne-15% ye-helium, kwaye kude ne-800 km phantsi kwamafu kukho i-sea abilayo. Ngokubhekiselele kwiNeptune, i-spacecraft yenzeke ukulungisa ii-geyser ezikhoyo kwiindawo zaso. Ngeli xesha, oku kukuphela kokufundwa kwamanzi amakhulu, kuba izazinzulu zibeka phambili eplanethi, apho, ngombono wabo, abantu bangaphila.
6. Kuphiliswa nguGawulayo
Izazinzulu ziye zasebenza iminyaka emininzi ukudala iyeza elingawunqoba i-AIDS, elibulala inani elikhulu labantu emhlabeni jikelele. Imbali iyayazi umntu omnye oye wakwazi ukunqoba le ngxaki, i-American Timber Ray Brown, ubizwa ngokuba "ngumguli waseBellin".

Oogqirha bathi umnikeli unentshukumo engavamile yokuguquka kwemfuyo enika intshutshiso kwintsholongwane kaGawulayo, kwaye yadluliselwa kuRay. Kwiminyaka emithathu kamva wafika ukuza kuhlola, kwaye intsholongwane yayingekho egazini lakhe.
7. Ukutshatyalaliswa kotywala kotywala
Le meko ibonakala ithathwa kwi-fable ngemouse, eyawela emthonjeni kunye nobhiya, kwaye yenzeke eLondon ekuqaleni kweXIXX. Kwi-brewery yendawo ngo-Oktobha 1814, kwenzeka ingozi, eyabangela ukuqhuma kwetan ngebhiya, eyayiqhubhisa i-ketk reaction kwezinye iitanks. Konke oku kuphelile nge-1.5 million yezilitha zebhiya ezijikeleza ngesitalato. Wadiliza yonke into endleleni yakhe, wabhubhisa izakhiwo waza wabangela ukufa kwabantu abayisithoba, omnye wabo owafa ngenxa yokutyhelwa kotywala. Ngelo xesha, eso siganeko saziwa njengeentlekele zemvelo.
8. Ulwaphulo-mthetho lwentsebenzo
Kukho amaninzi amaninzi xa abahlaseli bezama ukubamba inqwelo-moya, kodwa kanye kuphela kwimbali yeso sizathu siphumelele. Ngomnyaka we-1917, uDan Cooper wagibela i-Boeing 727 waza wanikela umgcini wendiza apho wayethi kukho ibhokhwe kwipotfoliyo yakhe kwaye wafaka phambili iimfuno: ezine iiparachuthi kunye ne-200,000 zamawaka. I-theorrorist yakhulula abantu, yafumana yonke into ayicelileyo, yalela umqhubi amagama athathwe. Ngenxa yoko, u-Cooper wenyuka ngemali phezu kweentaba, kwaye akukho mntu wambona kwakhona.
9. Umcimbi weCarrington
Into ekhethekileyo yenzeke ngo-1859 ngoSeptemba 1. I-Astronomer uRichard Carrington waphawula ukukhanya kwiLanga elibangele isiqhwithi esinzulu sogubhu lwe-geomagnetic ngaloo mini. Ngenxa yoko, amanxibelelwano e-telegraph aphikisiwe eYurophu nakwiMntla Melika, kwaye abantu behlabathi lonke babenokubona izibane ezisenyakatho, ezikhanyayo.
10. Umlambo obulalayo
Enye yezilwandle ezinobungozi ikhona kwintlambo ye-volcano eCameroon, kwaye ibizwa ngokuba yi "Nyos". Ngomhla ka-1986, ngo-Agasti 21, i-reservoir yabangela ukufa kwabantu, njengokwanda kwemveliso ye-carbon dioxide, eyasasazeka kwi-27 km ngefog. Ngenxa yoko, abantu abayi-1.7 bafa kwaye izilwanyana ezininzi zafa. Iingcali zenzululwazi zicebise izizathu ezibini: igesi eqokelelwe phantsi kwelabi okanye isenzo sezintaba-mlilo zamanzi. Ukususela ngelo xesha, isebenza kwi-degassing iqhutywe rhoqo, oko kukuthi, izazinzulu zikhupha i-gas outflows ukuze ziphephe loo ntlekele.
11. Iingoma zikaMtyholi
Into engaqondakaliyo, eyinto engummangaliso, yenzeke ngobusuku ngomhla we-7 ukuya kwe-8 kuFebruwari ngo-1855 eDeonon. Ekhephu, abantu bafumanisa umkhondo ongaqhelekanga oshiywe ngamagqabi, kwaye bacinga ukuba uSathana ngokwakhe udlulile apha. Ekumangalisiwe ukuba iingoma zazilinganayo kwaye zazikude kuma-20-40 cm. Babengekho kuphela emhlabathini, kodwa kunye nophahla lwezindlu, izindonga kunye namasango angena kwiindawo zokuhambisa amanzi. Abantu bavumelanisa ngokuqinisekileyo ukuba abambonanga mntu kwaye abavanga isandi. Iingcali zenzululwazi zazingenaso ixesha lokujonga imvelaphi yale mizila, njengoko iqhwa lichithwe ngokukhawuleza.
12. EmaNiga Falls asele
Isakhiwo esincomekayo samanzi aphefumulayo, esingaba nemiphumo emibi. Ukumisa le nkqubo, ngo-1969 urhulumente waseMelika neKhanada waqala ukuzama ukukhulisa ukuphuma kwamanzi, kodwa oku akuzange kusebenze. Ngenxa yoko, ityala elitsha lenziwe, apho i-Niagara yavunyelwa ukungena khona. Ngenxa yokuba impompo isomile, abasebenzi bakwazi ukudala idama nokuqinisa iintlambo. Ngaloo xesha, i-Niagara Falls yawa yintsikelelo enkulu, kuba abantu babefuna ukubona lo mcimbi oyingqayizivele ngamehlo abo.
13. Amabhashe awathatha iinqanawa
Oku, kuyandila, kodwa ibali liyaziwa xa amahhashi aneenkwenkwezi athatha iinqanawa ezibandakanya iinqanawa ezili-14 kunye neenqwelo ezili-850 kunye neenqanawa ezininzi. Kwenzeke ebusika ngo-1795 kufuphi ne-Amsterdam, apho iinqanawa zaseDatshi zazinamathele khona. Ngenxa yeqabunga elinqabileyo, ulwandle lwaluqweqwe ngamanzi, kwaye iinqanawa zazibanjwe. Ndiyabulela uncedo lwendalo, amaqela aseFransi akwazi ukufikelela kwiinqanawa aze azibambe.
14. Shintsha udidi lwegazi
Umhlali wase-Australia, uDemi-Lee Brennaya oneminyaka eli-9 nguyena kuphela umzekelo xa umntu utshintshe uhlobo lwegazi. Le ntombazana yatyhulwa kwisibindi kwindoda kunye neenyanga ezimbalwa kamva oogqirha bafumanisa ukuba wayenombono weR Rh owawuyinto engalunganga ngaphambili, kodwa waba nesimo esihle. Iingcali zenzululwazi zithi le nto yakwenziwe yinto yokuba isibindi sasinama-stem cells ezithatha indawo yamaseli e-stem yentolongo yamathambo. Inkqubo efanayo yenziwa ngenxa yokukhuseleka kwe-Demi.
15. Khokela iMasks
Ngo-1966 ngo-Agasti 20, kufuphi ne-Vinten entabeni kufuphi nedolophu yaseBrazil yaseNiteroy, kwafunyanwa amadoda amabini afileyo.
