Ukuze bathole ulwazi emazweni angaphandle, abantu kufanele basebenzise izitho zezinzwa.

Nokho, umsebenzi wezitho zezinzwa zabantu siqu ekutadisheni izenzakalo zemvelo kanye

imithetho nemisebenzi yokukhiqiza akwanele. Ukuze uvumelane nalokhu, izinzwa ziyadingeka. Ngakho-ke,

kungashiwo ukuthi inzwa isandiso sezici zomuntu, ezaziwa nangokuthi izici zikagesi.

        Ngokufika kwenguquko entsha yezobuchwepheshe, umhlaba uqala ukufaka ulwazi

iminyaka yobudala. Enqubweni yokusebenzisa ulwazi, into yokuqala okufanele ixazululwe ukuthola okunembile nokuthembekile

ulwazi, futhi inzwa iyindlela eyinhloko nezindlela zokuthola ulwazi kumvelo kanye

izinkambu zokukhiqiza.

        Ekukhiqizeni kwanamuhla kwezimboni, ikakhulukazi ohlelweni lokukhiqiza oluzenzakalelayo, izinzwa ezihlukahlukene

kufanele isetshenziselwe ukuqapha nokulawula imingcele ehlukahlukene enqubweni yokukhiqiza, ukuze i

izinto zokusebenza zisebenza esimweni esijwayelekile noma esimweni esihle kakhulu, futhi umkhiqizo ungafinyelela ikhwalithi engcono kakhulu.

Ngakho-ke, kungashiwo ukuthi ngaphandle kwezinzwa eziningi ezinhle kakhulu, ukukhiqizwa kwesimanje kuzolahlekelwa isisekelo.

        Ocwaningweni lwesihloko esiyisisekelo, inzwa inesikhundla esigqame kakhulu. Ukuthuthukiswa kwesimanje

isayensi nobuchwepheshe sekungene ezindaweni eziningi ezintsha: isibonelo, ukubuka indawo yonke eyizinkulungwane

weminyaka yokukhanya ku-macro, ukubona umhlaba wezinhlayiyana ezincane njenge-fm ku-micro, ukubona

ukuvela kwezidalwa zasezulwini amakhulu ezinkulungwane zeminyaka emi mpo, kafushane njenge-instante

ukusabela kwe-s. Ngaphezu kwalokho, kube khona ucwaningo oluhlukahlukene lobuchwepheshe olubalulekile

indima ekujuleni ukuqonda okubalulekile, ukuhlola amandla amasha nezinto ezintsha, ezifana nokuphezulu kakhulu

izinga lokushisa, izinga lokushisa eliphansi kakhulu, ukucindezela okuphezulu kakhulu, i-vacuum ephezulu kakhulu, insimu yamagnetic enamandla kakhulu,

insimu kazibuthe ebuthakathaka kakhulu njalo njalo. Ngokusobala, akunakwenzeka ukuthola inani elikhulu lolwazi

okungafinyeleleki ngokuqondile ezinzwa zomuntu ngaphandle kwezinzwa ezifanele. Ucwaningo oluningi oluyisisekelo lwesayensi

izithiyo, okokuqala, ubunzima bokuthola ulwazi lwento, kanye nokuvela kokunye okusha

izindlela kanye nezinzwa zokuthola ukuzwela okukhulu kuvame ukuholela ekuphumeleleni kulo mkhakha. Intuthuko

kwezinye izinzwa ngokuvamile yisandulela ekuthuthukisweni kwezinye iziyalo fringe
