Today Recall this Book welcomes Zachary Horton, Associate Professor of Literature and director of the Vibrant Media Lab at University of Pittsburgh; game designer, filmmaker and camera designer. Out of all these endeavors, he came to talk about his book The Cosmic Zoom Scale, Knowledge, and Mediation.

This dizzying book begins with a bravura description of a movie we both loved as kids: The Powers of Ten by Charles and Ray Eames. It's a view of two people enjoying a picnic zooms up and away to show their surroundings, all the way up into space then zooms back in for a close-up of the hand of the picnicker, ending top at the atomic level . The book, uses the cosmic zoom as a starting point to develop a cross-disciplinary theory of scale as mediated difference.

Zach shares his worries about scale literacy, and what happens when we diverge from the "meso-scale of the human sensorium." John approaches scale by way of Naturalism and SF in the late 19th century, both of which refuse the meso-scale aesthetic realism of their day in order to anchor it at a different scale. Elizabeth asks about temporal scales and geology's activation of human sense of humans' scalar insignificance.
