Uzuza kimwe mubihe bigwira hanyuma urebe impinduka.
Kubworoshye, ukwezi bisobanura impuzandengo y'amezi yose (Gashyantare = iminsi 28).
Ibibazo bishimishije nibisubizo bijyanye nigihe
Igihe ni iki?
Harya amasaha angahe kumunsi?

Gupima Ntagereranywa: Ubwihindurize, Isi yose, n'amayobera yigihe
Gupima umwanya nigice cyingenzi cyamateka yumuntu, kandi mugihe cyibinyejana byinshi, uburyo butandukanye bwagiye buhinduka kugirango bapime neza igihe cyigihe cyangwa ibikorwa runaka. Bumwe mu buryo bwa mbere ni izuba, ryakoreshaga umwanya w'izuba mu kwerekana amasaha y'umunsi. Nkuko ikoranabuhanga ryateye imbere, nuburyo bwo gupima igihe harimo isaha ya pendulum, chronometre de marine nisaha ya quartz. Amasaha, ni mato kandi yoroheje, ubu nuburyo busanzwe bwo gupima igihe, hamwe nisaha ya digitale itanga ibyasomwe neza. Ibipimo byigihe nabyo byakozwe hifashishijwe amasaha ya atome, akoresha ihindagurika rya atome kugirango apime neza neza kwiyongera kwigihe gito.
Igihe ni igitekerezo cyibanze mu gusobanukirwa isi n umwanya dufite muri yo. Nibintu byibanze byukuri, kandi nikintu twese duhura nacyo kandi twumva neza.
Kuri shingiro ryayo, igihe nuruhererekane rwibintu bibaho mwisi yose. Nibipimo byigihe cyibyabaye nintera hagati yabyo, kandi numubare wibanze ukoreshwa mukugereranya igihe cyibyabaye. Igihe kirashobora gupimwa muburyo butandukanye, uhereye kumurongo woroheje wizuba hejuru yikirere ukageza ku isaha nyayo yisaha.
Kimwe mu bintu by'ingenzi biranga igihe ni rusange. Igihe kirengana ku kigero kimwe kuri buri wese, aho yaba ari hose cyangwa icyo akora. Ibi bivuze ko igihe gitanga urwego rusanzwe rudufasha kugereranya igihe cyibyabaye no guhuza ibikorwa byacu hamwe.
Ikindi kintu cyingenzi cyigihe ni ukudasubira inyuma. Igihe kigenda gusa, kandi ntibishoboka gusubira inyuma no kubyutsa ibyahise. Ibi bivuze ko duhora tugana ahazaza, kandi ko buri mwanya wihariye kandi udasubirwaho.
Nubwo ifite ishingiro, igitekerezo cyigihe kiracyari impaka n’ibiganiro byinshi hagati yabafilozofe, abahanga, naba tewolojiya. Bamwe bavuga ko igihe ari ikinyoma, kandi ko ari imyubakire yumuntu dukoresha kugirango twumve isi. Abandi bavuga ko igihe ari ukuri kandi gifite intego, kandi ko ari ikintu cy'ibanze cy'isi n'ijuru.
Tutitaye ku kuntu dutekereza ku gihe, biragaragara ko igira uruhare rukomeye mubuzima bwacu. Ihindura ibyatubayeho, itwara isi karemano, kandi itanga urwego rusange rwerekana abantu bose. Igihe gishobora kuba igitekerezo kidasanzwe kandi cyoroshye, ariko nikimwe tudashobora kubaho tudafite.
