Hvem er Arkimedes?
Arkimedes var en siciliansk-født greske matematiker, fysiker, astronom, filosof og ingeniør som levde mellom 287-212 f.Kr. Løftekraft vann angivelig funnet i et bad er det mest kjente bidraget til vitenskapen, men faren til integrert beregningen etter mange matematiske historikere er Arkimedes.
Når det romerske generelle Marcellus beleiret Sirakuza, vil han måtte ta byen på grunn av våpen ingeniør kalt Arkimedes hadde gjort. De fleste av dem var mekaniske mekanismer og var skapt for å inspirere noen vitenskapelige regler. For eksempel vedhjelp av valser, ble svært tung steinene gravd opp til buskene og kastet bort med katapulter. Det er også rykter om at Arkimedes brent den romerske marinen ved hjelp av speil. Men i 212 f.Kr., romerne tok Sirakuza og drept Arkimedes sammen med andre avanserte ankomster av byen. Han sa, i mellomtiden Arkimedes tenkte på å løseet problem han trakk på jorden, og han fortalte en romersk soldat som kontaktet ham å gå bort og la ham være; Men soldaten drepte ham umiddelbart, ignorerer Arkimedes. Den romerske generalen har vært veldig opprørt av mordet på denne sværttalentfulle vitenskapsmann, hvor historien er en sjelden rase.
Arkimedes er både en fysiker, en matematiker og filosof. Han ble funnet i Alexandriafor en stund i sin ungdom, hvor han ble venner med Eratosthenes, og da han fikk brev med ham. Oppfinnelser gjort innen mekanisk Arkimedes inkluderer sammensattevalser, uendelig skruer, hydrauliske skruer og brennende speil. Han har forlatt mange jobber i feltet geometri i matematikk, som bidrar til statisk og hydrostatisk fysikk.
En av de viktigste bidragene til geometrien er at det viser seg at overflaten av en kule tilsvarer 4ΠR2 og dens volum er 4/3 πr3. Det har vist at pi-verdien er mellom 3 L/7og 3 10/71, beviser at en leilighet er lik til omkretsen av denne sirkelen og høyden tilsvarende radius av trekanten.
En av Arkimedes smarteste matematiske prestasjoner er utviklingen av noen metoder for å finne områder buede overflater. En Parabel kutt cutting rektanglet, mens enuendelig liten nærmet kontoen. Uendelig liten kontoen er legge til en liten bit av den minste delen som kan forstås i et matematisk. Denne kontoen har en veldig stor datoverdi. Han senere dannet grunnlaget for utviklingen av moderne matematikk ogdannet et godt grunnlag for differensial og integral kalkulus funnet av Leibniz og Newton.
Arkimedes har vist at for en Parabel kuttet av metoden for kvartil er lik 4/3 i feltet aven trekant med samme base og høyde, i sin bok, som er quadruentation av Parabolin.
Vitenskapsmannen som avslører prinsippene i likevekt for første gang er Arkimedes.Noen av disse prinsippene er:
Lik vekter er balansert i lik armene.
Ulike vekter forblir i balanse når følgende betingelse er oppfylt i ulike armene: F1 · A= F2 · b
Basert på arbeidet sitt, sa han, "gi meg et fotfeste, jeg skal gå jorden."
Arkimedes har også funnet loven på balansen av væsker anerkjent av sitt eget navn.Det sies at en dag, King II Hieron var mistenkt for miksing sølv i gull kronen gullsmeden hadde gjort, og løsningen på dette problemet ble overført til Archibiet. Selv omhan hadde mange trodde, Arkimedes, som ikke kunne finne ut av problemet, gikk tilet bad å bade, følte hans vekt redusert i badekaret, og sa, "Jeg fant det," han hoppet ut av badet. Jeg lurer på hva Archişet funnet. Et objekt som senkes i vann ville miste vekt så mye som vekten av vannet det bærer, og vannet som var gitt til kronen blesammenlignet med vannet som kronen hadde steinet og problemet kan løses.
Før Arkimedes forskning, ble det kjent at tronen svømte men jern sank; Men grunnen til det var ikke forklart. Arkimedes loven har vist at det er ingen plass for tilfeldigheter i naturen, at de samme resultatene vil alltid bli oppnådd i samme vilkår. Arkimedes, 23 århundrer siden, fant en svært nær forståelse av den moderne vitenskapelige tilnærmingen, statisk og hydrostatisk lovene som gjelder i dag, og de har tjent retttil å bli en av de tre største heltene i vitenskapens historie.
Arshimedess forsvar av Syracuse
I 216, Arkimedes hadde overskredet 70 år, sa at Siracusa kongen Hieron var død, enav hans slektninger. På slutten av den andre Pön krig, ble byen beseiret og Carthageenige om å forene. På toppen av at romerne sendt Claudius Marcellus, en av sine berømte konsul, til Siracusa med en hær.
Gamle Arkimedes, som aldri hadde vært involvert i politikk av sitt arbeid, ga seg enstille og rolig liv. Men landsmenn, som beundret og, ønsket å hjelpe ham med å forsvare byen. Arkimedes har avtalt å denne samtalen av ikke ønsker.
Romerne ikke utsette lære hans kreative evner som en oppfinner og ingeniør. En dag, oppdaget en romersk krigsskip, som ble lokket til bymuren i fjæra, plutselig en gigantisk, kjempestor tang. Verktøyet som kom ut av baksiden av veggene knust detmellom hans kjever som han tok skipet fra baugen. Arbeider prinsippene av dette verktøyet, som fungerer ved hjelp av spaker og roterende trinser, ble avslørt av Arkimedes. Dermed ble en leverage mekanisme gjennomført som et prinsipp om gangen.
I mellomtiden var gigantiske katapulter plassert bak veggene tunge piler og stenerpå fienden. Masten av fartøyene med hull i kortstokken og røret smuldrer, faller påskipet, fienden LED store tap.
Det sies at Arkimedes reflektert solstrålene på fienden gjennom et stort speil og sette skip i brann. Men denne historien, som er veldig vanskelig å tro, er kanskje ikke mer enn en myte.
Men maskiner som Arkimedes oppfunnet var øynene til romerne som hadde vært så lenge, da de så et tau eller en tryllestav på veggene, de skrek og kjører bort. Claudius Marcellus forstått at sin egen ingeniører ikke kunne takle sin fiende, om han beundret det eller ikke. "Hvorfor slåss med denne matematiske kjempen? Han sitter påkysten og ødelegger vår flåte som han gjør narr av oss! "han sa, og Siracuza har tatten full blokade.
