Ekhasini 239 lencwadi yami yelebhu, ngidwebe isikhathi sokugcina ngesikhathi sokugeza izandla izingilazi. Lezo ntambama ezichithwe zilwa nezinsalela eziqinile, lezo zinsuku zonakaliswe yizilingo ezingcolile—konke kwaba umlando ngokufika kweumshini wokuwasha izingilazi ozenzakalelayo.

Ngivule umshini ngamandla, ngabeka iflaski elinomthamo onama-reagents e-organic erekhini, ngavala umnyango wekamelo, ngakhetha"Ukugeza Okungokwemvelo"uhlelo, futhi ngacindezela ukuqala. Ngaphakathi, izingalo ezijikelezayo zavuka zaphila, amaza amanzi ejikeleza njengoba isikrini sokubonisa silandelela idatha yesikhathi sangempela: izinga lokushisa lamanzi, ubude bomjikelezo, ingcindezi yokufafaza, ukuhanjiswa kwamandla. Ngefasitela lokubuka, ngabuka njengoba yonke iminonjana yokugcina ye-reagent incibilika—kwanelisa ngokujulile.

Lokho okwake kwathathwaabantu abathathu imizuzu engama-90ukukhuhla—intaba yama-beakers angu-200ml—manje kwase kuhlanzwe kahle endaweniUmjikelezo ojwayelekile wemizuzu engama-40Kodwa umlingo awuzange uphele ekugezeni. Ngemva komjikelezo, ngingakhethaukomisa, umsebenzi obekulokhu kuyinkinga isikhathi eside ekuhlanzweni ngesandla. Manje, ngomyalo owodwa,umshinikushintshelwe kalula ekomeni, okwenza"ukusetshenziswa kokugeza-komile"iqiniso. Yonke inqubo, kusukela ekuhlanzeni kuya ekomiseni, yenzeka ngaphakathi kwegumbi elivaliwe—ukungenelela komuntu okungekho, akukho bungozi bokungcoliswa ngesikhathi sokudluliselwa, futhi akukho bungozi bokuchayeka kubasebenzi belabhoratri.

Njengoba iqembu lamaflaski afudumele acwebezelayo liphuma ekamelweni, kwangithinta:Lo mshinikwakungeyona nje indawo yokuhlanza; kwakuyindlelaumlindi wesango ngokumelene nephutha lokuhlolaNgokushintsha ukuguquguquka kwabantu ngezinqubo ezijwayelekile, kwaguqula ukuzala kabusha kwaba yinto eqinisekile. Ekufuneni kwethu impumelelo yesayensi, mhlawumbe intuthuko yangempela iqala lapha—kule mijikelezo yobumsulwa elawulwa ngokucophelela.
