Feynman: 'The Quest for Tannu Tuva" Part Four

Continuing the story of physicist Richard Feynman's fascination with the remote Asian country of Tannu Tuva, and his efforts to go there with his great friend and drumming partner Ralph Leighton (co-author of the classic 'Surely You're Joking, Mr Feynman'). Feynman was dying of cancer when this was filmed, and died a few weeks after the filming. This is Part Four of five. Originally shown in the BBC TV science series 'Horizon' in 1988, and also shown in the USA on PBS 'Nova' under the title 'Last Journey of a Genius'
