Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Pazano raG. I. Taylor uye kurudziro, Dyson akatamira kuUnited States muna 1947 seCommonwealth Fellow kuti awane dhigirii rechiremba wefizikisi naHans Bethe paCornell University (1947<unk>48). Ikoko akasangana naRichard Feynman. Nyanzvi yefizikisi yechiNgezi yakanga ichangotanga yakaziva kupenya kwechiAmerica chakapenya, uye yakazvibatanidza nokukurumidza sezvinobvira. Akabva aenda kuInstitute for Advanced Study (1948<unk>49), asati adzokera kuEngland (1949<unk>51), kwaakanga ari mushandi wekutsvakurudza paYunivhesiti yeBirmingham. Muna 1949 Dyson akaratidza kuenzana kwezvinyorwa zviviri zve quantum electrodynamics (QED): Richard Feynman's diagrams uye nzira yevashandi yakagadzirwa naJulian Schwinger naShin'ichirō Tomonaga. Iye akanga ari munhu wokutanga pashure pomusiki wavo kukoshesa simba rezviratidziro zveFeynman uye pepa rake rakanyorwa muna 1948 uye rakabudiswa muna 1949 rakanga riri rokutanga kuzvishandisa. Akataura mupepa iroro kuti mifananidzo yaFeynman yakanga isiri bedzi chishandiso chokuverenga asi rondedzero yechisiko ndokukudziridza mitemo yemifananidzo iyo yakagadzirisa chose chose chinetso chokudzokorora. Pepa raDyson uyewo hurukuro dzake dzakaratidza dzidziso dzaFeynman dzeQED muchimiro icho vamwe vezvemuviri vaigona kunzwisisa, zvichirerutsa kugamuchirwa kwenharaunda yefizikisi yebasa raFeynman. J. Robert Oppenheimer, zvikurukuru, akapwiswa naDyson kuti rondedzero itsva yaFeynman yakanga ichishanda sezvakaita yaSchwinger neyeyaTomonaga. Oppenheimer akapa Dyson mubayiro wokugara paInstitute for Advanced Study, "nokuda kwokundiratidza kuti ndakanga ndakanganisa", maererano nemashoko aOppenheimer. Muna 1949, Dyson akatangawo kugadzira zvinhu zvinonzi Dyson series. Yaiva pepa iri rakafuridzira John Ward kuti awane mukurumbira wake weWard <unk> Takahashi. Muna 1951 Dyson akabatana nechikoro paCornell semupurofesa wefizikisi, kunyange zvazvo akanga achiri asina dhigirii, uye muna 1953 akagamuchira nzvimbo yekusingaperi pa Institute for Advanced Study muPrinceton, New Jersey, kwaakagara. Muna 1957 akava mugari wemo weUnited States ndokurega kuva chizvarwa cheBritain....  Mubvunzo: Chii chaiva zita rebasa iro Dyson aishanda pariri?
