Café Scientifique with Professor Terry Jones, on "Life on Earth: The Origin of Elements." Recorded at the Bryant Lake Bowl on 12-20-11. Here is the description of the talk: "The only elements made in the Big Bang were hydrogen and helium; the building blocks essential for life were nowhere to be seen. So, where did the carbon in our bodies come from? Terry Jones, professor of astronomy at the University of Minnesota, explains how elements like oxygen and iron were made, and how they came to be incorporated into our home planet, making life on Earth possible."
