In this video excerpt from NOVA: "Hunting the Elements," New York Times technology columnist David Pogue learns about a set of elements commonly referred to as rare earths. Hear how rare earths are often used in technological applications and visit a rare earth mining site to learn more about where they are mined. Discover that rare earths are not really that rare and explore how their atomic structures make them nearly indistinguishable from one another.
