Uma abantu abaningi bezwa 'ukwenziwa kwesihlabathi ngokwezifiso', babona ingxenye embi, ephuma kanye, mhlawumbe eyephrojekthi yokubuyisela noma i-prototype. Lokho kuyingxenye yakho, impela, kodwa kuyisihloko se-iceberg. Ukujula kwangempela—futhi lapho kuhlala khona ubuhlungu bekhanda nokunqoba—kukukusebenzisela lokho okuyikho: inqubo eguquguqukayo kakhulu, engabizi kakhulu yomthamo ophansi kuya omaphakathi wamajiyometri ayinkimbinkimbi ezinye izindlela ezingakwazi ukuthinta ngaphandle kwezindleko zokuhlanya. Umbono oyiphutha ukuthi 'lula' noma 'isikole esidala'. Akunjalo. Kumayelana neziguquguqukayo ezilawulwayo kulokho okuyinqubo ngokwemvelo eyisiyaluyalu. Ukuthola lokho kulawula kahle kuwumdlalo wonke.
Umongo Wokwenza Ngokwezifiso Akukona Nje Ukuma
Ngakho, yini eyenza kube 'isiko'? Akukhona nje ukulandela umdwebo weklayenti. Iqala ngephethini. Ngomsebenzi wangempela wangokwezifiso, sivame ukukhuluma ngegwebu elifakwe ngomshini (njenge-EPS) noma amaphethini okhuni, akhelwe lowo msebenzi othile. Iphethini yiphuzu lokuqala lesinqumo esibalulekile. Ingabe utshala iphethini ehlala isikhathi eside uma ulindele ukuphinda ama-oda? Ngike ngabona izitolo zilahlekelwa yimali ngokushibhile ngephethini, kuphela ukuthi iphenduke ngemuva kokusetshenziswa okumbalwa, ilahle konke ukusakaza ngokulinganayo. Iphethini isisekelo, ngokwezwi nezwi nangokomfanekiso.
Bese kuza isihlabathi ngokwaso. Isihlabathi esiluhlaza, i-resin-bonded, i-sodium silicate... ngayinye inendawo yayo. Ukuze uthole iphaseji yangaphakathi eyinkimbinkimbi yendlu yephampu, ungase udinge umgogodla wesihlabathi se-resin esinamandla anembile ukuze ubambe umumo wawo ngaphansi kwensimbi kodwa ubuye ugoqe ukuze uphume. Ukukhetha isistimu yokuhlanganisa okungalungile kuwumgodi wakudala. Ngikhumbula inqwaba yabakaki bensimbi ababelokhu bekhala ezishisayo.
