Nigute Abakera basannye imisumari mugihe hatariho imisumari?

Dukurikije amakuru, gukuramo imisumari byamenyekanye bwa mbere muri Amerika no mu Burayi, ariko mu myaka ya za 1930, Umunyamerika Voss Foucault ni we wa mbere wasabye ipatanti. Kuva icyo gihe, imisumari yakwirakwiriye ku isi.

Muri iki gihe, iyo dukosoye imisumari, dukuramo imisumari. Ariko, gukata imisumari byavumbuwe mu kinyejana cya 20. None, ni gute abakera basannye imisumari mugihe hatariho imisumari? Uyu munsi, aYaQin diamant itangaizakumenyesha uburyo abakera basannye imisumari.

Nkuko baca umugani: Abantu bakura umusatsi mubwisanzure kandi imisumari ikura mubwisanzure. Mubyukuri, uburebure bw'imisumari nabwo bujyanye n'imyaka. Dukurikije imibare, imisumari y'abana ikura kuri mm 0,7 mu cyumweru. Iyo bakuze, umuvuduko wabo wo kwiyongera uriyongera. Nyuma yabantu bakuru, imisumari ikura ku kigereranyo cya 1 kugeza kuri 1,4 mm buri cyumweru, ariko abantu benshi bakura imisumari nyuma yimyaka 30. Umuvuduko uzatinda.

Byongeye kandi, imisumari ikura vuba mu cyi, itinda mu itumba, yihuta mu gitondo, kandi itinda nijoro. Kunyunyuza kenshi kandi bizihutisha imikurire yimisumari, abantu rero bamenyereye imisumari yiburyo bakura vuba kurusha ibumoso. Iterambere ryikura rya buri musumari ntabwo risa neza, mubisanzwe igihe kirekire urutoki, niko imisumari ikura vuba.

Aya mabanga mato mubyukuri kuruhande rwacu, ariko abantu benshi ntibayavumbuye.

Muri iki gihe, iyo urutoki rwabantu rumaze gukura, bazakoresha imisumari yo kubisana. Nigute abakera basannye imisumari mugihe hatabayeho gukuramo imisumari? Buri munsi umwanditsi w'inyuguti z'Ubushinwa yarebye mu makuru abona igisubizo.

Dukurikije amakuru y’amakuru, abantu baracyari mu gihe cy’inguge, kimwe n’inyamaswa zo mu gasozi zo muri iki gihe, nk'impyisi, ingwe, n'ingwe, zisya ingoyi ku biti, ku biti, no ku mabuye. Ariko, abantu bamaze gutangira gukoresha ibikoresho, mugihe cyibuye, imisumari yabantu yatunganijwe kumabuye cyangwa kumusenyi utoroshye.

Mu gihe cya Bronze, abantu batangiye koza imisumari ku cyuma cy'umuringa. Nyuma, abantu bahimbye dosiye. Iyi dosiye ni kure cyane ya dosiye yuyu munsi, ni ukuvuga ko hari uduce duto duto dusohoka kumuringa, hanyuma tukayinyunyuza. Nyuma, abantu bavumbuye imikasi.

Kugeza ubu, imikasi yacukuwe mu mva za kera z’ingoma y’iburengerazuba ya Han i Luoyang imaze imyaka irenga 2100. Mu kinyejana cya 6 nyuma ya Yesu, imikasi yinjijwe mu Buyapani kuva mu Bushinwa maze itangira gukorwa no gukoreshwa ku bwinshi mu gihe cya Edo.

Mbere yo gutema imisumari, nibyiza kuvura uruhu rwapfuye no guhamagara kumisumari kugirango imisumari ikure neza. UwitekaYaQin diamantisize hamwe na diyama iramba, irwanya ubukana bwa diyama kandi igashyirwa ku nkoni idafite ibyuma, ishobora gukuraho vuba kandi neza uruhu rwapfuye no guhamagara ku nzara. Irashobora kandi gukoreshwa mukuvura cicicle. Irashobora kugira ubwoko butandukanye bwimiterere ijyanye numurimo wifuza.
