Maumbirwe Earth: ane pfungwa dzekare uye tsvakurudzo ano

mibvunzo yakawanda rizere pamwe Galaxy, asi chimiro Pasi haakonzeri chero kusava nechokwadi. Redu riri muchimiro ane ellipsoid, kureva, vanhuwo nyika, asi chete zvishoma flattened matanda pedyo South uye North. maonero aya Earth yakaumbwa kwemazana emakore inonetsa nebope pakati chitendero nesayenzi. Nhasi, mudzidzi chikoro ose zvokutanga vachakwanisa kupindura zirokwazvo zvakanaka panyaya iyi.

Nhoroondo ano nyika mashoko

About chii nyika ichokwadi, isu nharo chaizvo munhoroondo yose kukura ruzivo yesayenzi. Homer vakafungidzira kuti redu ane denderedzwa mutsa, uye Anaximander vakati kuti anotarisa rwakaita humburumbira. Zvichida vose anoyeuka yakajeka mifananidzo giredhi satin 5th, apo chimiro Pasi sokunge denderedzwa uye musi mumwe njiva, iyo yakavakirwa nzou matatu, uye zvichingodaro. D. Once pakanga kunyange kubvuma kuti pasi redu riri muchimiro chikepe kuyangarara pamusoro zhinji gungwa kana hunopfuura payo muchimiro chepamusoro gomo!

shanduro dzakasiyana-siyana pakati kwepasi

Kwete chete kumubvunzo chimiro musha wedu nyika, asi kusunungurwa kwepasi ndavhiyiwa yakawanda kuchinja munhoroondo yebudiriro. Mukupera kwezana remakore rechi19 yakanga vaidavira kuti nyika yakanga zvose chose mira. Zvadaro, mukuru wemauto sayenzi vakatanga kuomerera pfungwa yokuti zuva zvinofamba vakakomba nyika, uye kwete vakutarisire. In nzanga dzakasiyana musoro zvakadai chimiro uye kufamba panyika, manyawi pfungwa masayendisiti kwete chete. Zvikasadaro hazvibviri kutsanangura utsinye mutongo D. Bruno, vane maonero pamusoro kwepasi akanga akasiyana panguva iyoyo kubva mwero mutongo. Zvinosuruvarisa pamutemo sayenzi haina nguva dzose kwakavakirwa itsva, akazaruka, uye vaifarira yokupura dzechitendero zvakavimbika migwagwa. The polymath vekutanga zvechokwadi akaratidza fungidziro pamusoro kwebasa nyika kumativi zuva uye kwete ndiEzekieri, aiva Pole Copernicus.

ano buri

Kupfuura zvose pedyo chokwadi F. Bessel - musayendisiti German yakatanga vakaverenga flattening Nyika nharaunda iri matanda. Izvi manhamba avapo muzana remakore rechi19 uye kumbochinja kwemazana emakore. Chete muzana remakore rechi20, FN Krasovsky - musayendisiti Soviet, akabudisa mashoko matsva kuti yakanga yakarurama kupfuura nhamba vakawana ndamboudzwa mugadzi ake. Kubvira ipapo, ellipsoid nemashoko kukura nyika inobereka zita rake. Maumbirwe Pasi anenge sebhora, flattened panguva matanda nzvimbo, uye musiyano pakati radii - Equatorial uye polar - ndiyo 21 makiromita. Nhamba iyi inoramba dzose kubvira 1936.

mhedziso

Zvakanaka, kuti kunyatsoenderana, maererano achangobuda umboo kwesayenzi vanoumba nyika - the geoid. Ndiwo chaiwo mufananidzo, riri kupfuura zvose pedyo wechokwadi muenzaniso Pasi. Geoid, sezvo nyika yedu ine dzegirini uye kwakadzikira. Research uyewo AA Ivanov, Russian musayendisiti hemisphere havana symmetry, uye neequator - ane ellipse, kwete denderedzwa. Ndizvo sainzi zvikamuka, uye ndiani anoziva tichadzidza zvakawanda pamusoro kwedu nyika mumakore 100? Panguva ino, muhofisi neimwe chikoro inomira yaizivikanwa pasi pose, umo tinodzidza zvakavanzika pasi.
