Richard Feynman was not only an iconoclastic and influential theoretical physicist and Nobel laureate but also an explorer at heart. Feynman through video recordings and comments from his friend and drumming partner Ralph Leighton tell the extraordinary story of their enchantment with Tuva, a strange and distant land in the centre of Asia. While few Westerners knew about Tuva, Feynman discovered its existence from the unique postage stamps issued there in the early 20th century. He was intrigued by the unusual name of its capital, Kyzyl, and resolved to travel to the remote, mountainous land. However, the Soviets, who controlled access, were mistrustful, unconvinced that he was interested only in the scenery. They obstructed his plans throughout 13 years. The majority of the scenes are extended narratives by Feynman. There is included a delightful extended discussion and demonstration of Feyman's bongo playing. Feynman explains how he used a phrase book of the Tuva language to write and express an interest in visiting there. The proposed trip took years to arrange. The programme never does get to show Feyman in Tuva; he died of abdominal cancer a few days after the recorded interview, at age 69 in February 1988. The story is interspersed with earlier recorded conversations by Feynman that add his perspectives on the nature of physics. So, this is not a travel documentary at all; rather it is another fascinating insight into the exciting personality of Richard Feynman. "You have no responsibility to live up to what other people think you ought to accomplish." - Richard Feynman (1918-1988).
