Ellen Wayland-Smith, Professor (Teaching) of Writing at USC, author of Oneida: From Free Love Utopia to the Well-Set Table (Picador, 2016) and The Angel in the Marketplace: Adwoman Jean Wade Rindlaub and the Selling of America (University of Chicago Press, 2020), discusses her latest book, The Science of Last Things: Essays on Deep Time and the Boundaries of the Self (Milkweed Editions, 2024). Here, she discusses two chapters, “Object Permanence” and “Quartz Contentment,” followed by a substantive discussion that ranges across topics of the book and to issues related to writing and rhetoric. These issues touch on personal loss and grief, the experience of time and scale, the use of scientific concepts in humanities work, and turtles.
