Tom Paradise is an American geomorphologist and professor of geosciences at the J. William Fulbright College of Arts and Sciences of the University of  Arkansas. He is also the guy you'll remember from PBS Nova's Petra: The Lost City. In this exciting episode, we chat about fun things like gems, cultures, parures, digging in Santa Barbara, and art that provokes.
