In each episode of Picturing Knowledge, hosts Kevin Hong and Ethan Perets look closely at an image and ask experts to help unpack its complexities. Our conversations reveal how our values participate in the visualization process–the creation and consumption of images–and how we might critically consider the decisions that shape our pictures of the world. We explore how images affect knowledge formation, and how technologies of visualization enable us to imagine invisible phenomena and events of almost unthinkable scale. Picturing Knowledge foregrounds visual literacy as a central challenge of our times: visualization holds the power to shape our common truths, values, and goals.

In the first episode, Ethan and Kevin speak to Dr. Emily Candela (Royal College of Art) about the history of the Center for Disease Control and Prevention’s 2020 image of the coronavirus and how this visualization became an icon of the COVID-19 pandemic. Unexpected connections are made between the coronavirus visualization and the parallel histories of X-ray crystallography and design in mid-20th century England, especially through the work of the Irish scientist and artist Helen Megaw, who crossed scientific and artistic networks during the period.
