Ngomzuzu yisikhathi lapho isimo selanga esibhakabhakeni siphezulu

Ukuqaphela phakathi nosuku ukuhamba kwelanga esibhakabhakeni, indoda iye yazama ukuthola incazelo kusukela ezikhathini zasendulo. Ukuthembela ekukhanyeni kwencazelo yesikhathi, ekubunjweni kokuphila kwezomnotho nokuphila kwansuku zonke kwakha isimo sengqondo kuye njengonkulunkulu. Izinkolelo mayelana nenqola yezinqola ezenza uhambo oluhamba nsuku zonke esibonakala esibhakabhakeni zibonakala emasikweni abantu abaningi. Kuyaqondakala ukuthi ukuphela kwalesi sivumelwano - umzuzu lapho isikhundla selanga esibhakabhakeni siphezulu, sakha isisekelo sokubala isikhathi.

Emini

Iqiniso lokuthi i-Sun ayihambisani noMhlaba, kodwa ngokuphambene, ekugcineni yaqondwa kuphela phakathi nekhulu le-16. Futhi omunye wabantu abashilo lo mbono (Copernicus), wayenesiqiniseko sokuthi uphikisana nokusobala - ukuthi umuntu angayigcina nsuku zonke, ukuthi ngaphambi kokushicilelwa kwakhe mayelana nesistimu ye-heliocentric ngamazwi mayelana nokungaziqondi kwawo okusobala.

Manje ingane yesikole iyazi ukuthi empeleni ukunyakaza kwe-disk yelanga esibhakabhakeni kungumphumela wokujikeleza kweMhlaba ojikeleze i-axis yayo, leyo mpuquko ephelele iplanethi yethu yenza ngosuku lapho isikhundla selanga ngaphezu komkhathi ngesikhathi esithile kuncike kuphela ekungeniweni kokujikeleza kuya ekukhanyeni. Lithinta isikhundla esiphethwe nguMhlaba ngenkathi kusakazwa kwansuku zonke emhlabeni jikelele. Ebusika enyakatho hemisphere, isikhanyiso sethu sikhuphuka emini ephansi kunehlobo.

Zenith

Ukuze uqonde ngokunembile ukuthi isikhundla selanga esibhakabhakeni siphezulu, kubalulekile ukuqonda ukuthi lesi simo sikalwa kanjani. Uma iphuzu eliphakeme kakhulu lesikhungo se-disk emini sitholakala ncamashi ngaphezu kwekhanda (khona-ke isibonda sinyathelwe emhlabathini ngokuqondile, sibamba isithunzi), ngakho-ke umbonisi use-equator.

ENyakatho Yenkabazwe, iphuzu le-zenith, i-angle enkulu yokuthambekela kwelanga ngokubhekiselele emkhathini emini, noma isikhundla selanga emini, ishintshela enyakatho, eNingizimu yeNyakatho yeNingizimu Afrika ihamba eningizimu unyaka. Isizathu esiyinhloko sokuguqulwa kwonyaka ngokuphakama kwelanga ngaphezu kwelanga emini yi-slope ye-axis of rotation ye-globe endizeni ye-orbit. Ihlala njalo futhi ilingana no-23.5 °.

Ebusika kanye nehlobo

Ukuthambekela lokhu kuchaza nokushintsha kwezinkathi emhlabeni wethu. Amaphuzu okubhekisela ekuqaliseni ubusika bezinkanyezi noma ihlobo yi-solstice amaphuzu. ENyakatho YaseNyakatho, usuku lwe-summer solstice luyi-Juni 21 no-22. Kulolu suku ukuthi ilanga lingaphezu kwakho konke esibhakabhakeni. I-angle yemisebe yelanga ebusweni beplanethi injalo kangangokuthi itshisa phezulu. Kancane kancane ukushisa amanzi amaningi kanye nomhlaba futhi kwandise izinga lokushisa lomoya. Ngaleso sikhathi inyakatho ye-hemisphere ibheke ilanga.

Ebusika, ngoDisemba 21 no-22, ngasenyakatho ye-equator emini, lapho isikhundla selanga esibhakabhakeni siphezulu, senyukela ngaphezu kwezulu ukuphakama okungenani, uma sithatha ushintsho kwalesi sibonakaliso phakathi nonyaka. Ngakho-ke indawo yethu yomhlaba isuswa kude nenkanyezi eyinhloko yesistimu elanga, ithola ukushisa okungenani okuzuzisa kakhulu. Eningizimu yezwe, konke okuphambene nalokho.

Isikhathi seqiniso (sezinkanyezi)

Ukubonakala kwama-unit of time enjalo njengonyaka, inyanga nosuku kuhlotshaniswa nokubonwa kwezinkanyezi futhi kuxhomeke ngokuqondile ekuxhumaneni phakathi kweplanethi ehleliwe kanye nenkanyezi ephakathi. Ukuhlukaniswa kube amahora, imizuzu nemizuzwana ihamba ngokungaqondile. Isici esiyinhloko sokubukeka kwezinombolo ezinjalo kuyisimiso sezinombolo zesigodi nesimademeshini, esasiyendabuko yeBabiloni lasendulo - ngqo kusukela lapho izingxenye zanamuhla zokulinganisa kwesikhathi zitholakala.

Inkathi edlulayo phakathi kwezikhathi lapho isikhundla selanga esibhakabhakeni siphezulu kakhulu-okubizwa ngokuthi usuku - aluzinzile ngonyaka. Ukushintsha kwemehluko kufinyelela emaminithini angu-30 futhi kuchazwa yi-shape elliptical ye-orbit lapho umhlaba uhamba khona nxazonke. Uma isikhathi sangempela sisetshenziswe ekusebenzeni, kuzodingeka ukuthi udale iwashi ngenkambo engalingani. Ngokusemandleni manje kungenzeka, kepha esikhathini sethu, lapho ukuchithwa okuphezulu kokuvumelanisa kwezenzakalo ezenzeka ezindaweni ezihlukahlukene zeplanethi kuyadingeka, uhlelo olunjalo lubonakala lungasebenzi.

Isikhathi esiphezulu

Ukuze ulinganise umehluko wonyaka phakathi nezinsuku zezinkanyezi, izazi zezinkanyezi ziye zazisa okuthiwa "isilinganiso esijwayelekile". Lo mqondo ongokoqobo wemfundiso uveza iphuzu elikhomba isikhundla sesibonakaliso sethu esibhakabhakeni, ukuhamba okuyizinsuku ezingu-365 ngokulinganayo. Ngonyaka kabili ngonyaka isikhundla saso sihambisana nendawo ye-Sun. Lokhu kwenzeka ezinsukwini zokwabelana kwe-equinox entwasahlobo nasekwindla.

Ukwethulwa kwe "Sun Sun" kwaholela ekusetshenzisweni okulula ngokwengeziwe ngesikhathi sokusebenza phakathi, okunye okubizwa ngokuthi umphakathi. Ngakho-ke, ngosuku oluhlukile ezinsukwini ze-equinox, ukushaywa kwehora leshumi nambili kwewashi akusho neze isikhathi sosuku lapho isikhundla selanga siphezulu. Ukubala umzuzwana ofanayo ngokunemba kwezingxenyana zesibili, sebenzisa "isikhathi sokulinganisa", equkethe idatha esuselwe ekuxhumaneni kwendawo ethile.
