Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muenzaniso we geocentric wakapinda muGreek astronomy uye uzivi pakutanga; inogona kuwanikwa mu pre-Socratic uzivi. Muzana ramakore rechi6 BC, Anaximander akakarakadza dzidziso yenyika yose ine Pasi rakaumbwa sechikamu chetsvimbo (chirongo), yakachengetwa mudenga pakati pezvinhu zvose. Zuva, Mwedzi, uye mapuraneti zvaiva maburi mumavhiri asingaoneki akapoteredza Pasi; kupfurikidza nemaburi, vanhu vaigona kuona moto wakavanzwa. Panenge panguva imwe cheteyo, Pythagoras aifunga kuti Pasi rakanga riri denderedzwa (maererano nokucherechedza kwokuparadzwa kwezuva), asi kwete pakati; vaidavira kuti rakanga riri mukufamba rakapoteredza moto usingaoneki. Gare gare mirangariro iyi yakabatanidzwa, naizvozvo vaGiriki vakadzidza zvikurusa vomuzana ramakore rechina BC vakafunga kuti Pasi rakanga riri bhora riri pakati pechisiko chose. Muzana ramakore rechina BC, vazivi vaviri vechiGiriki vane pesvedzero, Plato nomudzidzi wake Aristotle, vakanyora mabasa akavakirwa pamuenzaniso we geocentric. Maererano naPlato, Pasi rakanga riri denderedzwa, risingachinji riri pakati pezvinhu zvose zvakasikwa. Nyeredzi namapuraneti zvaitakurirwa zvakapoteredza Pasi pamapuraneti kana kuti madenderedzwa, akarongwa mumutsara (kunze kubva pakati): Mwedzi, Zuva, Venus, Mercury, Mars, Jupiter, Saturn, nyeredzi dzakarongwa, nenyeredzi dzakarongwa dziri papuraneti yokudenga. Mu"Ngano yaEr" yake, chikamu cheRepublic, Plato anorondedzera nyika yose seSpinil of Necessity, inoshanyirwa neSirens uye inotenderedzwa neFates nhatu. Eudoxus weCnidus, uyo akashanda naPlato, akagadzira tsananguro isiri yokufungidzira, yemasvomhu yokufamba kwenyika yakavakirwa pamashoko aPlato okuti zviitiko zvose zviri mumatenga zvinogona kutsanangurwa nokufamba kwakatenderera kwakafanana. Aristotle akatsanangura zvakadzama gadziriro yaEudoxus.  Mubvunzo: Ndiani akatanga dzidziso yokuti nyika yakatarisana nenyika?
