Whai muri i te whakaekenga o Pearl Harbor i kawe mai i te United States ki te pakanga, i whakauruhia a Feynman e Robert R. Wilson, e mahi ana i runga i nga tikanga hei whakaputa i te uranium whakatipu hei whakamahi i te poma ngota, hei waahanga o te kaupapa Manhattan. I mahi te rōpū a Wilson i Princeton i runga i tētahi pūrere e kiia nei ko te isotron, i whakaritea hei wehe i te uranium-235 mai i te uranium-238 mā te hiko hiko. I mahia tenei i runga i te tikanga tino rereke mai i te mea i whakamahia e te calutron i hangaia e te roopu i raro i te kaiako o Wilson o mua, a Ernest O. Lawrence, i te Laboratory Radiation o te Whare Wananga o California. I runga i te pepa, he nui ake te kaha o te isotron i te calutron, engari i uaua a Feynman raua ko Paul Olum ki te whakatau mehemea he whaihua, kaore ranei. I te mutunga, i runga i te taunakitanga a Lawrence, i whakarerea te kaupapa isotron. I tenei wa, i te timatanga o te 1943, i whakatuhia e Robert Oppenheimer te Los Alamos Laboratory, he taiwhanga huna i runga i te mesa i New Mexico ka hangaia, ka hangaia nga poma ngota. I tukuna he tono ki te kapa o Princeton kia tukuna atu ki reira. "Pērā i te tokomaha o nga hoia ngaio", ka mahara a Wilson i muri ake, "i hainatia e matou, he tokomaha, kia haere ki Los Alamos". Pēnei i ētahi atu kaitōrangapū rangatahi, ka hinga a Feynman i raro i te whakairo o te Oppenheimer ātaahua, nāna i waea mai ki a Feynman mai i Chicago ki te whakamōhio atu ki a ia kua kitea e ia he whare hauora i Albuquerque, New Mexico, mō Arline. Ko rātau i roto i te hunga tuatahi ki te haere ki New Mexico, i runga i te tereina i te 28 o Poutu-te-rangi 1943. I whakawhiwhia e te rori tereina a Arline ki tetahi tuuru wira, ana ka utua e Feynman he utu mo te ruuma motuhake mo ia. I Los Alamos, i tohaina a Feynman ki te Tari Theoretical (T) a Hans Bethe, a i tino miharo ia ki a Bethe kia waiho hei kaiarahi roopu. I whakawhanakehia e ia rāua ko Bethe te tātai Bethe<unk>Feynman mō te tātai i te kaha o te pōro, arā...  Pātai: He aha te āwhina a Feynmann ki ngā kaipūkaha?
