217 - A Song of Concrete and Ice (with Cristián Simonetti)

Cymene accounts for her mysterious conversion from a coffee-drinker to a tea-drinker but [spoiler alert] it turns out she’s not a doppelganger after all. Then after some EV road trip talk (16:06) we are delighted to have Cristián Simonetti join us from the Pontificia Universidad Católica de Chile. We start with Cris’s research on concrete, one of the most abundant contemporary materials, and what it reveals about the course of the Anthropocene trajectory. From there we talk about the debate over the Anthropocene designation and how stratigraphers tend to petrify earth processes by valuing solids over fluids. From there we move to talking about ice and his interest in the viscosity of glaciers and soil. We circle back to concrete and how the Romans conceived of it as a solid fluid and as a conversation between the elements. Finally, we talk about the special role glaciers have played in the Chilean Anthropocene. Glaciers move like ketchup? Concrete is a colloid? For those and further revelations, please listen on!
