Omkhulu Russian wemithi Alexander Butlerov futhi Dmitri Mendeleev

Omkhulu bamakhemikhali Russian baye bezilokhu eyaziwa ngeqhaza labo kuleli isayensi elokhu ivela. Kodwa mhlawumbe omunye evelele kunazo zonke yilezo bamakhemikhali njengoba Aleksandr Mihaylovich Butlerov futhi Dmitri Ivanovich Mendeleev, owaba ososayensi ziyaphawuleka, futhi namuhla eyaziwa hhayi kuphela e-Russia kodwa futhi emhlabeni wonke. Kulesi sihloko sizoxoxa biography kanye imisebenzi yesayensi lezi amadoda amakhulu kaNkulunkulu.

Aleksandr Mihaylovich Butlerov: Biography

Alexander Butlerov wazalwa engxenyeni yokuqala yekhulu le-19 emzini Chistopol. Ngenxa yokuthi wabonakala emndenini okhuluma ngomnikazi wezwe ocebile, umfana athola imfundo enhle. Ekuqaleni wafunda esikoleni kuyimfihlo, bese ubuye esikoleni esiphakeme, bese wabhalisa e-University. Kusukela ekuqaleni ukuqeqeshwa esikoleni esiphakeme waba nesithakazelo kwezilwane chemistry wezitshalo.

Umsebenzi yesayensi Aleksandr Mikhailovich

Okunjalo bamakhemikhali omkhulu Russian njengoba Aleksandr Mihaylovich Butlerov, negalelo elikhulu isayensi. Ngemva kokuthweswa iziqu, le nsizwa enquma azinikele isayensi usebe uprofesa e eminyakeni embalwa.

Nokho, entsheni ngenxa yokuluthwa chemical Alexander ejeza. Wayethanda ukuthi abangane bakhe benza sparklers, futhi uma ngisho iphutha lakhe, kwakubikwa kugqamuke amalangabi esikhungweni sokuphehla endlini isivakashi. Lokhu kwaba umphumela omunye ucwaningo lwakhe. Alexander wajeziswa. Ezinsukwini ezimbalwa nje yena wayengemuva egunjini lokudlela ukuze bonke ukubona, futhi entanyeni yakhe hung uphawu nge umbhalo oqoshiwe ongokwesiprofetho - ". Umthaki omkhulu"

Aleksandr Mihaylovich Butlerov, njengabanye bamakhemikhali omkhulu Russian ziye umxhwele cwaningo of udaba eziphilayo. Phakathi ezitholwe zakhe kakhulu esingabenzela yisho ukudalwa inkolelo-mbono yokuziphendukela odumile we isakhiwo sazo sekhemikhali.

Dmitri Ivanovich Mendeleev: Biography

Dmitri Mendeleev wazalwa ngo Tobolsk. Kusukela zisencane, unina Ngaqala ukuqaphela ukuthi ingane yakhe encane kunawo wonke (nesikhombisa ilandelana), uDmitri, i osemusha emangalisayo onekhono. Nokho, esikoleni wayengenasithakazelo kwamakhemikhali nhlobo - yayinesithakazelo kuphela kwi-mathematics ne-physics.

Ngo-1855, Mendeleev Dmitriy Ivanovich iziqu Petersburg Main Pedagogical Institute ke ngokushesha kulandele yesayensi yakhe eminingi amaphepha, imibiko kanye iziphakamiso.

Umsebenzi yesayensi ye uDmitry Ivanovich

Dmitri Ivanovich Mendeleev kuyinto isazi enkulu emkhakheni physics, tibalo, ezomnotho, i-meteorology, nabanye. Kodwa okubaluleke kakhulu umnikelo emkhakheni wesayensi yokuthakwa kwamakhemikhali. Ngaphezu singakuphathi ukuba kwakhe isazi olukhulu aluzange bacwaninga futhi ucwaningo, wabhala eziningi zomgunyathi nezindaba eziphathelene amaphepha ocwaningo, amagesi uphenyo, izixazululo, intsha oqeqeshiwe, wabhala ebhukwinitifundvo lokuqala eRussia - "Kubaluleka Chemistry", naye wathola into ukhiye kule ndawo. Kwakuwusuku uhlelo ngezikhathi izakhi zamakhemikhali, ie ithebula abadumile gqwa.

Abaningi bamakhemikhali omkhulu Russian bamangala futhi ngimangele yilo ukutholakala. Mendeleev hhayi kuphela kuletsa etafuleni zonke izakhi zamakhemikhali eyaziwa, kodwa futhi ukuba zibikezele ukubakhona labo abazange baphinde babonwe. Ngenxa ishadi lesikhathi abafundi nabafundi ke sekulula kakhulu ukufunda i-chemistry, futhi ososayensi ngokwabo - kulula yokuthola izinto siphinde sibuyisane idatha.

Mendeleev ngemva kokufa kwakhe, kushiya isizukulwane kuka 1,500 amaphepha isayensi. Ukuze kuhlonishwe Mendeleev ukuthi uqambe 101st chemical element - mendelevium.

Aleksandr Mihaylovich Butlerov futhi Dmitri Ivanovich Mendeleev - amabili umuntu ezithakazelisa kakhulu, ngubani wanikela ukuphila kwakhe ekucwaningeni kwesayensi okuphathelene futhi bathole okuningi okubalulekile. Njengazo zonke bamakhemikhali omkhulu Russian, bahlukile, futhi umsebenzi wabo ifundiswa amanyuvesi Russian angaphandle.
