This week’s Cultures of Energy podcast is brought to you by the number zero. Our co-hosts cover the need for more fun in academic life and Hollywood takes on the Anthropocene. Then (9:11) Cymene speaks with the ever joyful Diane Nelson, Professor of Anthropology at Duke University and author of Who Counts? The Mathematics of Death and Life after Genocide (Duke University Press, 2015). They talk hot-tub feminism, the power of numbers in how we think and feel about the world, genocide in the Capitalocene, and the politics of land, forests and hydroelectric power in Guatemala today. Diane offers us lessons from living in a country that has experienced massive human and environmental losses but also reminds us that, like the number zero, every end is also a beginning.
