I want to know the answer to the following question:
Where did Feynman work at in Brazil?
All the background I'm provided with is that "Feynman traveled to Brazil, where he gave courses at the BCPF (Brazilian Center for Physics Research) and near the end of his life schemed to visit the Russian land of Tuva, a dream that, because of Cold War bureaucratic problems, never became reality.". Is that enough to answer the question?
