Njengoba kuchazwa yi-Popular Science, izikhotha zingaziqondi ezingilobheni, nokho okubonwa kulezo zividiyo zezikhotha ezithakazelisayo noma ekhaya lakho. Yini engicabanga izikhotha uma zibona ezingilobheni? Lapha inkinga, izikhotha aziziqondi ezingilobheni. Uma zibona ukuziphendukela kwazo, zicabanga nje ukuthi zibona ikati elinye. Lokhu kuchaza ukuthi ikati lakho lizophenduka ngokuthandeka kakhulu kwalo. Isizathu sokungaziqondi izikhotha ukuthi zibuka zazo kwazo kungaba khulu. Ingabe izikhotha zinamahloni ezingilobheni? Izikhotha ezinye ziyayeka ngokuphelele ikati eliphendukayo […]

Amakhukhamba anepH esikhundleni sokuba phakathi kwe-5.1 no-5.7. Nokho, noma kunomthelela omuncane wokumuncwa, amakhukhamba awanamthelela omkhulu wokumuncwa emzimbeni. Ngenxa yemiphumela yabo yokumiswa yamanzi ekuqondeni, amakhukhamba ahlolwa njengokudla kwamanzi. Ingabe yisiphashini isimuncu noma isibese? Ngokubhekana nokukhathazeka kwentliziyo, amakhukhamba yidla yamanzi futhi ngakho isivimbelise isimuncu emzimbeni ngokukhuluza ipH. Yini ipH yekhukhamba? Amakhukhamba angakhuliswa ngempumelelo eminingi yemihlobiso. Umhlabathi othandwayo ungumhlabathi opholile, oqedile, ofakiwe kahle ngendlela yokudla kwemvelo nokudla kwemvelo. […]

Kuyacabangwa ukuthi uPluto uneziqu ezidabukisayo ngaphakathi futhi mhlawumbe unolwandle olungaphansi kwesimo, ngakho isimo sakhe sivalelwe ngoyiki oluqukethe amanzi, i-methane ne-nitrogeni. Ngenxa yokuthi ibhodi lezwe, umbala we-Pluto ubomvu, omhlophe, okhaki kanye nokhaki obomvu. Yini umbala wangempela kaPluto? Isimo se-Pluto sivalelwe ngoyiki oluqukethe amanzi, i-methane, ne-nitrogeni futhi kuyacabangwa ukuthi uneziqu ezidabukisayo ngaphakathi kanye nokungenzeka ukuthi unolwandle olungaphansi kwesimo. I-NASA ichaze isimo se-Pluto njengesimo esiphukene nasemaceleni, sibomvu, omhlophe, […]

Inkundla emhlophe iyingundla emnyama eyegijima ngemuva kwesikhathi. Njengoba izinkundla ezimnyama zidla izinto ngaphandle kokuphendula, kungakhathaliseki nokuthi izinkundla ezimhlophe ziziceke. Izinkundla ezimhlophe azikwazi ukukhona, ngoba zivukela umthetho wesibili wokushisa. Ayikho na imbangela yokuthi izinkundla ezimhlophe zingase zikhone? Impendulo emfushane, ngokunembeza, ayikho. Izinkundla ezimhlophe ziyizinto kuphela abasayensi abazikhumbulele – zingase zikhone, kodwa asikaze sibone eyodwa, noma sibone izimpawu ezinengi ezithi zingase zikhone. Okwamanje, yizo izindlela. Ukuyibeka ngokulula, […]

Ukuze kugcine imvu yezinkanda kanye nokuvikela ukukhula kwemvelo lapho kugcinwa khona, isixazululo sezikhemikhali, njenge-alkaline lye, singathunyelwa kumvu yezinkanda. Uma kufakwa, ukugqoka kwesikhemikali kudlalisana nesikhumba kwenza kube mnandi kanye nokuba nomunyu. Ngizenza kanjani ukukhwelela kwesikhumba ngemva kokubeka izinkanda? Ngcwele ngokuthula amafutha we-coconut, castor noma jojoba ukuze uvuse ukuhamba kwegazi kumakhala wezinkanda nokuphakamisa amacwebezelo adliwe.
