RICHARD FEYNMAN AND THE QUEST FOR TANNU TUVA. Here is a Youtube video of Richard Feynman and Ralph Leighton talking about their ten-year obsession with Tannu Tuva. Part One begins with postage stamps and music from Tannu Tuva (It seems unbelievable, but what seems to be flute music at the beginning of the video is apparently made by the singer.) . It features Feynman talking about what he is looking for in doing science. Here are links to Parts Two through Five which continue the story of Feynman’s efforts to get to Tannu Tuva.
