Zhozef Lui Lagranzh - kwezezibalo, ngeenkwenkwezi kunye injineli

Abaphengululi abaninzi bakholelwa ukuba Zhozef Lagranzh ayikho isiFrentshi, kunye yezibalo Italian. Yaye lo mbono ayikho ngaphandle kwesizathu. Ngapha koko, umphandi elizayo wazalwa eTurin ngowe-1736. Elubhaptizweni umfana yena ogama Giuseppe uLudovico. Uyise wabamba i-ofisi yezopolitiko omkhulu iyunithi yolawulo lwe eSardinia, kwaye ababekolo didi amanene. Umama weza kwintsapho oogqirha.

Intsapho bezibalo elizayo

Ngako oko, usapho lokuqala, apho ke wazalwa Zhozef Lui Lagranzh, kwakunzima owayesisityebi. Kodwa ke uyise ntsapho nexhala, ukanti, usomashishini sizingise kakhulu. Yaye kungekudala ezibe esengozini zonakalise. Kwixesha elizayo, आयडेंटीफिकेशन iSazisi uchaza ingcamango umdla kunene ngale iimeko zobomi okumehleleyo intsapho yakhe. Ukholelwa ukuba intsapho bakhe baphila ubomi abazizityebi bekhululekile, kunokwenzeka ukuba आयडेंटीफिकेशन iSazisi wayengenakuze baye ithuba ukuze alunxulumanise nakwizibetho zabo kwimathematika.

Le ncwadi, owaguqula ubomi

Umntwana elinanye ngabazali bakhe Zhozef Lui Lagranzh. ngobomi bakhe, nkqu ngokunxulumene oku kubizwa ngokuba uphumelele: ngokuba bonke abanye abantwana bakhe wafa yabantwana yasekuqaleni. Uyise आयडेंटीफिकेशन iSazisi yayimi ekubeni unyana Wabufunda mthetho. आयडेंटीफिकेशन iSazisi ngokwakhe ekuqaleni akazange engqondweni. Ekuqaleni wafunda kwi-College of eTurin, apho waba nomdla kakhulu iilwimi zasemzini kunye nezibalo apho elizayo okokuqala wayeqhelene imisebenzi Euclid ne Archimedes.

Nakuba kunjalo, kuza mzuzu sibi xa आयडेंटीफिकेशन iSazisi kuqala ebeganga iliso yomsebenzi kaGalileo othi "On indlela okuhlalutya amancedo." Zhozef Lui Lagranzh emangalisayo abanomdla kule ncwadi - mhlawumbi ukuba wajika yonke Isiphelo sakhe. Phantse nangoko, kuba kileyo Isazinzulu oselula kunye iilwimi zasemzini baba esithunzini lemathematika.

Ngokutsho kweminye imithombo, izibalo आयडेंटीफिकेशन iSazisi wasebenza ngokuzimeleyo. Ngokutsho kwabanye, waya iiklasi zesikolo eTurin. iminyaka Sele-19 (yaye ngokutsho kweminye imithombo - 17) Zhozef Lui Lagranzh owenza umsebenzi wokufundisa wezibalo eyunivesithi. Oku kungenxa yokuba abafundi kakhulu kwilizwe lethu ngelo xesha lwanikwa ithuba lokufundisa.

umsebenzi lokuqala: emanyathelweni Leibniz and Bernoulli

Ngoko ke, ukususela ngoku kwimathematika uba yokubanga आयडेंटीफिकेशन iSazisi ezinkulu. Ngowe-1754 wabona ukupapashwa isifundo yakhe yokuqala. Scientist wawenza ngokohlobo ileta sisazinzulu dei Italian Toschi Fagnano. Kodwa apha आयडेंटीफिकेशन iSazisi wenza impazamo. Ungabinayo inkokeli yenzululwazi nokulungiselela ukudla zabo, ngoko likuthethayo, uphando lakhe sele kuqhutywa. Izigqibo ngayo yayiyeyabantu i Leibniz kunye uJohann Bernoulli. Zhozef Lui Lagranzh wada babesoyika izityholo zokuveza. Kodwa uloyiko lwakhe lwalungenasihlahla ngokupheleleyo. Kwaye ngaphambi imathematika ekulindeleke impumelelo enkulu.

Nolwazi Euler

Kule minyaka 1755-1756-nzulu oselula wathumela inxenye yoyilo zakhe kwezezibalo Euler, leyo ngokwenene malunga noku. Kwaye ngo 1759-m आयडेंटीफिकेशन iSazisi wathumela kuye omnye isifundo esibalulekileyo. Kuye enikelwe iindlela zokusombulula iingxaki isoperimetric apho Euler nzima iminyaka. Sesayensi onamava kakhulu ukufunyanwa wonwabe kakhulu आयडेंटीफिकेशन iSazisi oselula. Waze wenqaba ukupapasha ezinye izinto zayo entsimini leyo kwada ixesha ezifana Zhozef Lui Lagranzh akazange ukupapasha umsebenzi wabo.

Ngowe-1759, ngenxa ecetyiswa Euler, आयडेंटीफिकेशन iSazisi uye wakhonza njengelungu bezinye iintlanga Berlin Academy of Sciences. Apha Euler wabonisa iqhinga kancinane: emva zonke, wayefuna आयडेंटीफिकेशन iSazisi babehlala kufutshane kangangoko kuyo, ngoko ke nzulu oselula yakwazi ukuba ukufudukela Berlin.

Umsebenzi nokukhathala

आयडेंटीफिकेशन iSazisi yabandakanyeka nje kuphela uphando kwimathematika, ubucukubhede kunye neenkwenkwezi. Kwakhona wadala uluntu lwezenzululwazi, apho kamva waba Royal Academy of Sciences eTurin. Kodwa ixabiso ngenxa yokuba Zhozef Lui Lagranzh lenze iqela elikhulu ziyabethabethana kwimimandla ngqo yaye baba ngelo xesha sezibalo mkhulu ngeenkwenkwezi zehlabathi, yaqala etywaleni kukudakumba.

Qala zikhumbuze ukudinwa rhoqo. Oogqirha 1761 bathi asizi kuba noxanduva yempilo आयडेंटीफिकेशन iSazisi ukuba akazange ukufutha lokuphathana uphando yayo kwaye oko uzinzise ishedyuli yomsebenzi. Sezibalo akazange abonise self-ukuthanda kwaye sithobele iingcebiso oogqirha. impilo yakhe ngcono. Kodwa ukuxinezeleka zange ashiye naye kwada kwasekupheleni kobomi.

Uphando Astronomy

Ngowe-1762, i-Paris Academy of lokhuphiswano umdla wabhengezwa Sciences. Ukuthabatha inxaxheba kuwo kuyimfuneko ukuba anike umsebenzi sindululo kwenyanga. Apha आयडेंटीफिकेशन iSazisi kubonakala njengoko ngeenkwenkwezi uphando. Ngowe-1763 sithumela kwiKomishoni imisebenzi yayo phezu libration yeNyanga. Kwaye ke inqaku ngokwayo efika Academy ngaphambi kokufika आयडेंटीफिकेशन iSazisi. Isibakala sokuba imathematika kwafuneka ukuba baye eLondon, apho waye wagula kakhulu yaye kwafuneka ukuba bahlale Paris.

Kodwa apha आयडेंटीफिकेशन iSazisi wafumana inzuzo enkulu: kuba eParis wakwazi ukuba uqhelane namanye abaphengululi ezinkulu - d'Alembert. Xa ikomkhulu France आयडेंटीफिकेशन iSazisi wafumana ibhaso ngenxa yophando lwakhe phezu libration yeNyanga. Kwaye omnye umvuzo wawongwa umphengululi - kwiminyaka emibini emva koko yanikezelwa ukuze ekufundweni Hewana ezimbini kaZeyus.

ofisi eliphezulu

Ngowe-1766 आयडेंटीफिकेशन iSazisi wabuyela eBerlin kwaye ufumane ithuba lokuba umongameli we-Academy of Sciences kunye nentloko yesebe yayo yemvelo nakwimathematika. A lot of izazinzulu e Berlin zifunyenwe ezishushu kakhulu आयडेंटीफिकेशन iSazisi kuluntu lwabo. Wakwazi ukuseka ubuhlobo obuluqilima lo zezibalo Lambert, uJohann Bernoulli. Kodwa kule kuluntu kwakukho nabagxeki. Omnye wabo Castillon, ngubani wayeneminyaka engamashumi amathathu ubudala आयडेंटीफिकेशन iSazisi. Kodwa emva komzuzwana ulwalamano yazo iphuculwe. आयडेंटीफिकेशन iSazisi watshata Castiglione kamzala ogama Vittoria. Noko ke, umtshato wabo engenabantwana tsakanga. Amaxesha amaninzi umfazi ukugula wafa ngo-1783.

Ledger sesayensi

umphengululi zizonke eBerlin iminyaka engaphezu kwama-mabini. Lo msebenzi elinemveliso njenge "Mechanics zohlahlelo" आयडेंटीफिकेशन iSazisi. Olu phando ibhalwe ngexesha lokuvuthwa. Kukho nje ezimbalwa iinzululwazi omkhulu, phakathi ilifa eyayiza kuba umsebenzi obalulekileyo. "Mechanics kohlaziyo" sifana "ekuqaleni" Newton, kwakunye ne "iwashi pendulum" Huygens. Kwakhona baqulunqe odumileyo "I आयडेंटीफिकेशन iSazisi Umgaqo", igama elipheleleyo apho - ". Umgaqo d'Alembert-आयडेंटीफिकेशन iSazisi" Lingcwaba lomfo sigaba quadratic jikelele okuhambisa.

Ukufudukela Paris. longele yokuphila

Ngowe-1787 आयडेंटीफिकेशन iSazisi wafudukela Paris. Its waniliseke ngokupheleleyo kulo msebenzi e Berlin, kodwa kwafuneka ukuba, ngenxa yokuba ubume bolunye uhlanga emva kokufa Frederick II kwidolophu ngokuthe mandundu. E Paris, wokuwonga elaa abaphulaphuli yakomkhulu yabanjwa आयडेंटीफिकेशन iSazisi, nesezibalo wada wenza indlu kwi Louvre. Kodwa kwangaxeshanye eqalisa kwinkxalabo ngokunzulu kukudakumba. Ngowe-1792, enye ingcali yenzululwazi watshata okwesibini, kwaye ngoku umbutho Kwakumnandi omnye.

Ekupheleni nzulu ngobomi bakhe uvelisa umsebenzi omninzi. Umsebenzi yokugqibela, kuba ngawo uceba ukuthatha, wawuza kuphinda "Mechanics zohlahlelo". Kodwa ukwenza oku, oosonzululwazi akuphumelelanga. April 10, 1813 wafa Zhozef Lui Lagranzh. Ucaphula kuye, ingakumbi enye yokugqibela elichaza ubomi bakhe: "Ndenze iqhinga ... andizange ndamthiya mntu wenza bubi." Ukufa ISAZINZULU, ngathi ubomi, nokuzola - ehamba kunye uzive wanelisekile.
