Archimedes - xisaab Greek, khaawi "Eureka"

Archimedes - a xisaab Greek, khaawi "Eureka." Waxa uu ka mid ah kuwa ugu waa saynisyahano caanka ah tan iyo markii ay Qarniyadii hore. hawlaha Research Archimedes taabtay oo keliya ma aha ee xisaabta, sida dad badan u maleynayaa. Saynisyahanka cadeeyay in duurka ku of physics iyo xiddigaha, iyo xataa farsamo. Wuxuu u abuuray Eebe wax walba oo loo isticmaalay beeraha kala duwan ee hawlaha aadanaha, laga bilaabo beeraha iyo arrimaha ciidamada. Qaar ka mid ah qaybo ka mid horumartay by Archimedes waa ku saleysan badan aaladaha maanta. Tusaale ahaan, "Archimedes fur" waxaa loo isticmaalaa in ooyinka la taaban karo iyo gotaan hilibka. Tani saynisyahan Giriigga ee hore uu ahaa mid ka mid ah tirooyinka halyeey dhaqan dunida iyo taariikhda.

A yar Biography

miisaanka dahab ka go'ay loo yaqaan, laakiin dhib ah ee su'aasha waxa uu ahaa in milligram ee kuugu dhow ogaado xaddiga gol leeyahay, tan iyo taajkii waxaa caadi ahayn qaabeeya. Archimedes ma xallin karo dhibaato this. Marka, markii uu u qabeynin musqusha, ayuu waxaa lagu dhuftay fikradda ah: qoo sheyga, aad dhigay karaan ay mugga, qiyaasay mugga dareeraha barakacay waxaa by.

Sida ay legend, Archimedes in qaawan ku orday meesha bannaan oo leh cod weyn ku dhawaaqay oo ah "Eureka!", Taas oo macnaheedu yahay "waxaa helay!". Taasi waa sharciga ugu muhiimsan ee hydrostatics ayaa la furay ee la joogo.

cilmi sayniska

Inta ugu badan ee sayniska ayaa xisaab Greek qadiimiga. "Eureka" caanka ku ahaa ee uu hadal ma aha oo kaliya. Mar kale, oo dhan u sheeg halyeeyada: Hiero oo hadiyad ahaan u boqorkii dalka Masar, Blotemigii dhisay markab raaxo loo yaqaan "Sirokosiya". Laakiin markabka ma heli karo oo biyaha ku shubaa. Archimedes dhisay dallace silsilad - nidaam ee blocks, kaas oo uu u yimid in la sameeyo shaqo la mid ah dhaqdhaqaaqa gacanta. Just dhacdadan noqday marmarsiiyo oo uu weedha kale oo caan ah: "i sii hoosdhigaha iyo waxaan ku talaabsan doonaa dhulka '!.

xaqiiqooyinka Interesting ku saabsan xisaab ah

In sharaf of nin cajiib magacaabay bohol ah, asteriyoodh iyo jidadka ee magaalooyinka sida Amsterdam, Nizhny Novgorod, Donetsk, Dnieper ah, iyo, dabcan, meel ka mid ah Syracuse.

Leibniz mar hadlay weedha ah in haddii si taxadar leh ku baran shuqullada cilmiga, daahfurtay in sameeyey geometry mar dambe loo tixgeliyo cusub. Dhab ahaan, mid ka mid ah iyo badh kun oo sano, inta badan ee xisaabaha dadka Gariigta ah ee qadiimiga ah ayaa ku cel celiyo Newton iyo Leibniz oon.

dhimashada hanad

dunida oo dhan ogyahay waxa xisaab Giriigga ee hore, wuxuu sameeyey wax badan oo daahfurtay iyo waxay Been Abuuran. Yuu yahay Archimedes, xataa caruurta ay garanayaan. sida runta ah Waxa uu ahaa hanad ah. Noloshiisa oo ku wareegsan oo leh waxa qarsoon iyo halyeeyadoodii hore.
