Ubuningi kanye nezinto zokwakha
Inani elibonakalayo yinoma yini engalinganiswa ngokuqondile noma ngokungaqondile, futhi imiphumela ivezwa ngezinombolo namayunithi. Ukuphakama nobunzima kuyizibonelo zobuningi obubonakalayo obungalinganiswa ngqo. Isibonelo sobuningi obubonakalayo obungalinganiswa ngokungaqondile yivolumu. Uma ufuna ukuthola umthamo webhavu lokugeza endlini yakho yokugezela, qala ulinganise ubude, ububanzi, kanye nokuphakama kwebhavu usebenzisa i-tape measure noma i-ruler. Bese, phinda ubude, ububanzi, kanye nokuphakama ukuze uthole umthamo webhavu lokugeza.
Ngakolunye uhlangothi, noma yini engenakulinganiswa futhi ivezwe ngezinombolo namayunithi akuyona inani elibonakalayo. Mhlawumbe abangani bakho esikoleni bayakuncoma bathi umuhle noma umuhle, yize empeleni ubuso bakho bujwayelekile :). Ubuhle noma ubuhle abunakulinganiswa. Ungase ububone ubuhle bezimbali engadini yesikole... ubuhle abunakulinganiswa. Ngoba abunakulinganiswa futhi buvezwe ngezinombolo namayunithi, ubuhle, ubuhle kanye nobuhle akuzona izilinganiso ezingokoqobo. Ungabhala phansi izibonelo zezilinganiso ezingokoqobo ozaziyo?
Ubuningi obuphathekayo buhlukaniswe kabili, okungukuthi ubuningi obuyisisekelo kanye nobuningi obutholakalayo. Ubuningi obuyisisekelo buyinani eliphathekayo amayunithi alo anqunywe kusengaphambili futhi awatholakalanga kwamanye amanani. Ngo-1971, i-General Conference on Weights and Measures yasungula ubuningi obuyisikhombisa obuphathekayo njengobuningi obuyisisekelo noma obuyisisekelo , okuhlanganisa ubude, isisindo, isikhathi, izinga lokushisa, ugesi wamanje, inani lezinto kanye namandla akhanyayo. Ubuningi obutholakalayo buyinani eliphathekayo elitholakala enanini elilodwa noma ngaphezulu eliyisisekelo. Ngaphezu kwamanani ayisikhombisa ayisisekelo angenhla, amanye amanani aphathekayo afakiwe enanini elitholakale. Ezihlokweni zefiziksi ozozifunda kamuva, uzofunda ngobuningi obuhlukahlukene obutholakalayo.
