Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: United States yave iri mutungamiri mukuvandudzwa kwetekinoroji kubvira mukupera kwezana ramakore rechi19 uye kutsvakurudza kwesayenzi kubvira pakati pezana ramakore rechi20. Nzira dzokugadzira zvikamu zvinoshandurwa dzakagadzirwa neU.S. War Department neFederal Armories mukati mehafu yekutanga yezana ramakore rechi19. Iyi tekinoroji, pamwe chete nokugadzwa kweindasitiri yemashini, yakaita kuti U.S. ikwanise kugadzira michina yekusona, mabhasikoro, nezvimwe zvinhu pamwero mukuru mukupera kwezana ramakore rechi19 uye yakazozivikanwa sehurongwa hweAmerica hwekugadzira. Kuitwa kuti mafekitari ave nemagetsi pakutanga kwezana remakore rechi20 uye kuiswa kwomuchina wokuunganidza nezvimwe zvinhu zvinoponesa basa zvakaita kuti pave negadziriro inonzi kugadzirwa kwezvinhu zvakawanda. Muna 1876, Alexander Graham Bell akapiwa kodzero yokutanga yokuAmerica yokugadzira runhare. Rabhoritari yokutsvakurudza yaThomas Edison, imwe yokutanga yorudzi rwayo, yakagadzira giramufomu, girobhu rokutanga rinogara kwenguva refu, uye kamera yokutanga inoshanda. Yokupedzisira yakatungamirira kukuvapo kweindasitiri yevaraidzo yenyika yose. Mukutanga kwezana remakore rechi20, makambani emotokari aRansom E. Olds naHenry Ford akaita kuti mugero wokuunganidza motokari uve nomukurumbira. Vakoma Wright, muna 1903, vakaita ndege yokutanga inopfuurira uye inodzorwa ine simba rinorema kupfuura mhepo. Kukwira kwechiFascism neNazi muma1920 nema1930 kwakaita kuti masayendisiti mazhinji eEurope, kusanganisira Albert Einstein, Enrico Fermi, naJohn von Neumann, vatamire kuUnited States. Mukati meHondo yeNyika II, Manhattan Project yakagadzira zvombo zvenyukireya, ichitanga Nguva yeAtomu, nepo Mujaho weNzvimbo wakaburitsa kufambira mberi nekukurumidza mu rocketry, sainzi yezvinhu, uye aeronautics. Kugadzirwa kwe transistor muma1950, chinhu chakakosha chinoshanda mune zvese zvemagetsi zvemazuva ano, kwakatungamira mukuvandudzwa kwakawanda kwetekinoroji uye kuwedzera kwakakosha kweindasitiri yetekinoroji yeUS. Izvi, zvakazoita kuti pave nemakambani akawanda matsva ezvigadzirwa zvemazuva ano uye nzvimbo munyika yose dzakadai seSilicon Valley muCalifornia. Kufambira mberi kwakaitwa nemakambani eAmerica anogadzira zvinhu zviduku zvakadai seAdvanced Micro...  Mubvunzo: ndiani aiva nerabhoritari yakaita zvinhu zvakawanda zvatinoshandisa nanhasi?
