Usebenzisa umbhalo onikeziwe, khipha izincazelo eziningi zesayensi eqanjiwe
Context:Umbhali waseMelika wezindaba eziqanjiwe zesayensi nomhleli uLester del Rey wabhala, "Ngisho ne-aficionado ezinikele noma umlandeli unenkinga yokuzama ukuchaza ukuthi iyini inganekwane yesayensi", futhi ukungabi khona "kwencazelo egculisayo ephelele" kungenxa yokuthi "azikho imingcele ebekwe kalula kwezesayensi eqanjiwe". Ngokuka-Isaac Asimov, "Isayensi eqanjiwe ingachazwa njengalowo mkhakha wezincwadi okhuluma ngendlela abantu abasabela ngayo ekushintsheni kwesayensi nobuchwepheshe". URobert A. Heinlein wabhala ukuthi "Incazelo emfushane ewusizo cishe yazo zonke izindaba eziqanjiwe zesayensi ingase ifundeke kanje: ukuqagela okungokoqobo ngezenzakalo zesikhathi esizayo ezingenzeka, okusekelwe ngokuqinile olwazini olwanele lwezwe langempela, elidlule nelikhona, nasekuqondeni ngokujulile uhlobo nokubaluleka kwendlela yesayensi".  Ingxenye yesizathu sokuthi kube nzima kangaka ukuthola incazelo evumelanayo yezesayensi eqanjiwe kungenxa yokuthi kukhona ukuthambekela phakathi kwabathandi besayensi eqanjiwe ukuba benze njengabahluleli babo ngokwabo ekunqumeni ukuthi yini ngempela eyenza isayensi eqanjiwe. UDamon Knight wafingqa ubunzima, ethi "izindaba eziqanjiwe zesayensi yilokho esikhomba kukho lapho sikusho". UDavid Seed uthi kungase kube usizo kakhudlwana ukukhuluma ngezesayensi eqanjiwe njengokuhlangana kwezinye izinhlobo zezinhlobo nezinhlobo ezingaphansi.
