Throat singing for Feynman
Caltech physicist Richard Feynman famously developed an obsession with the tiny northern Asia country sometimes known as Tannu Tuva.
Though he continued to try to travel there late in his life, his quest to actually get to the remote place was cut short by a series of illnesses.
He settled for getting to know some of the great artists of the region, the throat singers, who can belt out two notes simultaneously -- one in the front of the mouth, another in the back of the throat.
This is Kongar-Ol Ondar, a master Tuvan throat singer who performed on Friday at Caltech's Beckman Auditorium as part of the TEDx event.
