Izithelo ziyadingeka ekudleni, nakuba umuntu ngamunye enezintandokazi zakhe nokuthanda kwakhe. I-apula ngokuvamile lingelinye elisetshenziswa kakhulu ngenxa yokunambitheka kwalo, kodwa asikunaki ukubukeka kwalo.
Wake wazibuza ukuthi kungani ine-dimple phezulu? Uma ngempela ilenga esihlahleni, kungani ingenawo umumo owengeziwe? Isayensi uveze ocwaningweni kungani ithola leso simo futhi ibe ne-cusp emise okwe-dimple.
Ukukhula kwe-apula kunikeza leso simo
Ngokuyisisekelo, le physiognomy ingumphumela wezigaba ezihlukene zokukhula phakathi kwesisindo nesiqu, ngokusho kocwaningo olusha lwezibalo lwesithelo. Ama-apula ayindilinga ngokuqhathaniswa, ngaphandle kwe-dimple phezulu. Kodwa, ithimba elivela eNyuvesi yaseHarvard eCambridge lahlela ukubona ukuthi lingakwazi yini ukuqonda ukuthi kungani lesi sithelo sinokuma kwaso okungajwayelekile.
Ososayensi basebenzisa ijeli ekwazi ukujwayela leso simo ngokuhamba kwesikhathi. Lokhu kwabasiza ukuba baphindaphinde indlela i-apula elikhula ngayo, futhi baliqhathanisa nokukhula kwama-apula angempela engadini yezithelo. Ukuhlanganisa lokhu nokumodela kwezibalo kwembula ukuthi ukwakheka kwesithelo (indlela esikhula ngayo izigqi ezahlukene kanye nokungazinzi kwemishini) babambe iqhaza ngokuhlanganyela ekuphakameni kwe-dimple, ama-ridges aphansi, kanye nokuma kwesithelo okuvamile.
UDkt Lakshminarayanan Mahadevan, umbhali oholayo wocwaningo, ngaphambili wayesungule ithiyori elula yokuchaza ukuma nokukhula kwama-apula. Kodwa-ke, le phrojekthi yaqala ukuthela izithelo lapho abacwaningi bekwazi ukuxhuma ukubonwa kwama-apula wangempela ngezigaba ezahlukene zokukhula.
Ithiyori yezibalo ixazulula okungaziwa
Ukuze baqonde ukuvela kokuma kwe-apula kanye ne-cusp, abacwaningi baphendukela kuthiyori yezibalo yakudala eyaziwa ngokuthi i-singularity theory.
Ithiyori yobunye isetshenziswa ukuchaza inani lezigigaba ezahlukene. Lokhu kungasetshenziswa ukuze ufunde mayelana nezimbobo ezimnyama noma izibonelo eziningi ezingabonakali, njengamaphethini akhanyayo ngaphansi kwechibi lokubhukuda nokusakazeka kokuqhekeka. «Lezi zindawo okugxilwe kuzo ngezinye izikhathi zingathatha isimo sokubumbana lapho ama-deformation akhona.kusho umbhali, wengeza ngokuthi "isibonelo esitholakala yonke indawo sibonakala esiqongweni se-apula, i-dimple yangaphakathi lapho isiqu sihlangana khona nesithelo.".
Ithimba labacwaningi liphakamisa ukuthi isici kuleli cala sincane ukuguqulwa kwejubane lokukhula eduze kwesiqu, uma kuqhathaniswa nezinye izingxenye ze-apula, kudala i-dimple. Ingaphezulu le-apula alinalutho olufana namaphethini okukhanya echibini lokubhukuda, kodwa linomumo ofanayo nabo.
Ithimba lisebenzise ukulingiswa kwezinombolo ukuze liqonde ukuthi kungani ukukhula koqweqwe lwesithelo nomongo kwenza i-cusp. Babe sebeqinisekisa ukulingisa ngokuhlolwa okulingisa ukukhula kwama-apula kusetshenziswa ijeli eyavuvukala ngokuhamba kwesikhathi. Ukuhlola kubonise ukuthi amazinga ahlukene okukhula phakathi kwenqwaba ye-apula kanye nesifunda sesiqu abangele i-cusp emise okwe-dimple.
Lezi zinguquko kanye nokuma kwe-cusp kubonakala kwamanye ama-apula nezinye izithelo, njenge amapentshisi, ama-apricots, cherry kanye plums. Ithimba lithole ukuthi ukwakheka kwesithelo kungase kube nokusebenza ngokuhlanganyela ngokudala ama-cusps amaningi kuzo zonke izithelo ezifanayo.
Ababhali bathi ubunjalo bezimpawu zamangqamuzana ezibangela ukuvimbela ukukhula eduze nesiqu kufanele buhlolwe esikhathini esizayo. Bafuna nokubheka izindlela ezixhumanisa amangqamuzana noshintsho ezicutshini zesithelo.
