Uyo akati "Eureka!"? Kunozivikanwa yawanikwa Archimedes musimboti

Vakawanda vedu kurangarira Archimedes kubva kuchikoro. Ndiye akati: "Eureka!" Shure kupinda nemvura uye vakaona kuti mvura pamwero akasimuka. Izvi zvakazoita kuti kunzwisisa kuti bhuku misha mvura inofanira kuva akaenzana Vhoriyamu anyatsofukidzwa chinhu.

Gold Korona Gierona

Pakanga kamwe mambo ainzi Hieron. Nyika, raakanga akamhanya, chaiva chiduku, asi chikonzero ichi kuti aida kupfeka korona makurusa munyika. kugadzira Its akarayira anozivikanwa mutengesi unyanzvi, achimupa pondo gumi zvendarama yakaisvonaka. Tenzi wakanyengwa basa mumazuva 90. Shure kwenguva ino, mutengesi vakauya korona. Raiva basa guru, uye munhu wose akazviona, akati kuti hazvina kuenzana munyika.

Mambo Hiero akaisa korona mumusoro wake, iye kunyange ainzwa zvishoma vachinyara, yakanga yakanaka chomumusoro. Zvizhinji kuyemura, akasarudza vanouyera pazviyero dzavo. Korona kwaiyerwa 10 pounds, sezvakanga zvarayirwa. Mambo akafara, asi achiri akasarudza kuratidza naye munhu akachenjera kwazvo murume ainzi Archimedes. Iye toyed pamwe wemaoresa chomumusoro uye vachinzvera, uye ipapo akataura kuti kuchena mumaoko mumwe mutengesi anogona kunyengedza goridhe, uye kuti achengetere chigadzirwa uremu kuwedzera yemhangura kana sirivha.

Kunetseka Hiero akakumbira Archimedes kupa naye uchapupu dzokudarika panyaya, kana tenzi akanga kutendeseka. The musayendisiti havana kuziva sei kuzviita, asi akanga asiri munhu anobvuma chinhu hazviiti. Iye nechido tichiita kugadzirisa matambudziko yakaomesesa, uye kana mubvunzo mhinduro naye, haana kurega kusvikira awana mhinduro. Saka zuva nezuva aifunga pamusoro goridhe uye vakaedza kuwana nzira paunogona kuongorora chitsotsi, pasina anokonzera zvakaipa Korona.

Great zvakawanwa netsaona

Archimedes kamwe mangwanani, kufunga korona yamambo, akanga achigadzirira nemvura. kugeza Large akazadzwa kusvikira pamuromo, paakapinda izvozvo, uye vamwe mvura leaked angonanga ibwe paburiro. Zvakafanana kwakatoitika nguva zhinji, asi musayendisiti wokutanga kufunga nezvazvo zvakakomba. "Mvura yakawanda sei ini vaidzvinyirirwa, achienda bhati?" - akabvunza pachake. - "mvura akauya chete sezvinongoitawo zvakanga ini. Man hafu saizi wangu bvikinyidza hafu. Zvakafanana chaizoitika kana tikaisa korona "iri nokushambidza.

Uyo akati "Eureka!"?

Gold kunorema zvikuru nokuda chaiyo arambe achirema pane sirivha. Uye pondo gumi zvendarama yakaisvonaka havazokwanisi kubvisa mvura sezvinongoitawo bvikinyidza makirogiramu manomwe endarama, hwakakanyiwa makirogiramu matatu esirivha. In sirivha hukuru Naizvozvo, mvura kuva makuru, uye zvichaita bvikinyidza kupfuura goridhe rakanatswa. Hooray, pakupedzisira! Ndaiona! Saka munhu akati, "Eureka!" Yakanga Archimedes. Kukanganwa zvimwe zvose, akakwakuka kubva kugeza uye, pasina kumbomira kupfeka pachake, akamhanya mumigwagwa kuna yamambo, vachidanidzira "Eureka! Eureka! Eureka! "Rinoshandurwa kubva revo yechiGiriki" Ndawana! Ndakawana! Ndakawana! "

Crown akaedzwa. Somugumisiro, mashoko mutengesi mhosva kwakaratidzei kupfuura musoro mubvunzo. Kana akarohwa kana kwete, nhoroondo iri akanyarara, Rinongoreva hazvina basa. Chinhu chinokosha ndechokuti iye akati, "Eureka!", In nemvura akaita chikuru zvakawanikwa, riri kupfuura Korona Gierona.

Pfungwa yokuti "Eureka"

Shoko Rinobatanidzwa ne heuristics, indasitiri ruzivo, rinoreva ruzivo uye kunzwisisa kugadzirisa zvinetso nedanho kudzidza uye kuita zvinhu. Kudanidzira uku chokuita musayendisiti Archimedes akati "Eureka" pashure pake musoro rakasvika chisarudzo mafungu aro panguva dambudziko. Ichi nyaya korona yendarama kokutanga akazviratidza kunyora mubhuku Vitruvius, mazana maviri pashure pokunge zvaitika.

Dzimwe nyanzvi zvinombokunetsa rakarurama nyaya iyi, vachiti kuti nzira iyi kunoda kunyatsoenderana kuyerwa kuti zvaizova zvakaoma kuita panguva. nezvinetso zvakafanana munyaya Galileo Galiley, kupa magadzirirwo hydrostatic nepakati, izvo zvinogona kushandiswa kuenzanisa uremu chakaoma guru chinhu pamwe chete chinhu, chete mumvura.

rusina mugumo okugadzira zvinhu

Mumwe mukuru uye inozivikanwa rengano inotenderera kunozivikanwa Archimedes. Uyo akati: "Eureka!"? Uye nei, Handizivi, zvakawanikwa huru dzakawanda dzinoitwa munguva zuva nezuva uye mabasa - muimba yokugezera, hope pasi pomuti? Archimedes akapfuurira kuita mupiro inokosha kukura nesayenzi. Famous yemasvomhu, yefizikisi uye nyanzvi, akaberekwa muna 287 BC muna Syracuse, Greek Colony muna Sisiri uye akafa muna 212 BC. e. panguva nechisimba nevaRoma. mutemo wake kuchikoro, uye achiri vaiona mumwe wenyanzvi dzesayenzi zvose.

Archimedes 'musimboti

Izvi musimboti wakakurumbira, achiperekedzwa nyaya dzinonakidza, rinoti sezvinotevera: kurema chete fuma anofanira kutora zvakafanana, pasinei fomu. Uyo akati "Eureka"? Uye zvinorevei? Raiva ngaukufadze panguva inokosha kuwanikidza. The Physics nhungamiro Archimedes kunorondedzerwa sezvinotevera: kana muviri achinyatsotaurira imwe mvura, rwunotanga kuita pamusoro buoyancy simba akaenzana kurema misha Urume.

Nei vamwe zvinhu kuyangarara uye vamwe vasingadaro? Izvi nokuda chinonakidza kuti buoyancy. Somuenzaniso, imwe simbi bhora richanyura, asi simbi zvakafanana uremu, asi chimiro mukombe kuchaita kuyangarara nekuti kurema iri vakaparadzira munzvimbo yakakura, uye arambe achirema hwendarira zvinova zvishoma kupfuura arambe achirema mvura. Muenzaniso kungava zvikepe huru, anorema matani akawanda uye kushambira mugungwa.
