Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I runga i te tohutohu me te taunakitanga a G. I. Taylor, ka neke a Dyson ki te United States i te tau 1947 hei Kaituku Commonwealth ki te whiwhi tohu tohungatanga ahupūngao me Hans Bethe i te Whare Wananga o Cornell (1947<unk>48). I reira i tutaki ai ia ki a Richard Feynman. I mohio te physicist Ingarihi budding te pūmanawa o te American papai, a piri ia ano rite hohoro rite taea. Na ka neke ia ki te Institute for Advanced Study (1948 <unk> 49), i mua i te hokinga ki Ingarangi (1949 <unk> 51), i reira ia he hoa rangahau i te Whare Waananga o Birmingham. I te 1949 i whakaatuhia e Dyson te taurite o nga whakatakotoranga e rua o te quantum electrodynamics (QED): Ko nga mahere a Richard Feynman me te tikanga kaiwhakahaere i whakawhanakehia e Julian Schwinger me Shin'ichirō Tomonaga. Ko ia te tangata tuatahi i muri i to ratou kaihanga ki te mauruuru i te mana o ngā mahere Feynman me tona pepa i tuhituhia i roto i 1948 ka whakaputaina i roto i 1949 ko te tuatahi ki te hanga whakamahi o ratou. I kī a ia i roto i taua pepa ehara i te mea he taputapu rorohiko noa iho ngā mahere a Feynman, engari he ariā ā-tinana, ā, i whakawhanakehia e ia ngā ture mō ngā mahere e tino whakaoti ana i te raruraru o te whakawāteatanga. Ko te pepa a Dyson me ana korero i whakaatu i nga ariā a Feynman mo te QED i roto i te ahua ka taea e etahi atu tohunga ngaio te mohio, hei awhina i te whakaaetanga a te hapori ahupūngao ki nga mahi a Feynman. Ko J. Robert Oppenheimer, i tino whakaponohia e Dyson ko te ariā hou a Feynman he rite tonu ki a Schwinger me Tomonaga. I whakawhiwhia e Oppenheimer a Dyson ki te whakatuunga i te Institute for Advanced Study, "mo te whakaatu i taku he", i roto i nga kupu a Oppenheimer. I te 1949, i roto i nga mahi e pa ana, i hangaia e Dyson te raupapa Dyson. Ko tenei pepa i whakaaweawe i a John Ward ki te whakaputa i tana tuakiri Ward <unk> Takahashi rongonui. I te tau 1951 ka uru a Dyson ki te karahipi i Cornell hei kaiwhakaako ahupūngao, ahakoa kaore ano ia kia whiwhi tohu tohungatanga, ana i te tau 1953 ka whiwhi ia i tetahi tuunga tuuturu i te Institute for Advanced Study i Princeton, New Jersey, kei reira tonu ia. I te tau 1957 ka riro ia hei tangata whenua o te United States, a ka whakarerea e ia tana whenua o Ingarangi....  Pātai: He aha te ingoa o te kaupapa i mahi ai a Dyson?
