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 "Out of his enthusiastic interest in reaching Tuva came the phrase "Tuva or Bust" (also the title of a book about his efforts to get there), which was tossed about frequently amongst his circle of friends in hope that they, one day, could see it firsthand.". Is that enough to answer the question?
Answer: no
