Humans have successfully utilized metals for millennia, and trace amounts of metals are crucial to our survival. Is that coincidence or something more? On this ID The Future, host Andrew McDiarmid begins a two-part conversation with Dr. Eric Hedin, professor emeritus of physics and astronomy at Ball State University in Indiana. Dr. Hedin tells the fascinating story of the origin of metals, the finely tuned set of conditions that allow for our use of metals, and the crucial role metals play in our survival. This is Part 1 of a two-part conversation. Look for Part 2 next!
