Cymene tells us about her struggles to get a passing grade in art class in this week's podcast. And then (15:20) we welcome a dear friend, Marina Peterson from UT-Austin, to the podcast. We start with her book Atmospheric Noise: The Indefinite Urbanism of Los Angeles (Duke UP) and its study of the making of atmospheres and noise pollution and how it helps us to attune to less earthbound dimensions of cities. We talk about her idea of using glitches to navigate the boundaries of science, art and ethnography. And we turn from there to new projects on cloud-seeding in LA, how the elements impact urban existence, folding and frequency. More on Yum Yum here. Hang in there, everyone, peace and love.
