99% Invisible's Roman Mars and Kurt Kohlstedt

Curious minds seeking more information on the untold secrets (literally) surrounding them should look no further than "99% Invisible," the podcast hosted by Roman Mars that reports on how our lives are impacted by the architecture, transportation and infrastructure of our cities. "99% Invisible" episodes address a wide variety of issues, from the effects of American car culture on policing to the confusions of print and virtual mapmaking.

In their new book The 99% Invisible City: A Field Guide to the Hidden World of Everyday Design, Mars and "99% Invisible" digital director and producer Kurt Kohlstedt share stories from the podcast that will both enlighten readers and encourage them to think more critically about their living environments. Join them both at INFORUM, where they will discuss the small marvels that make up our big world and the role that people played in building them. This conversation will be moderated by The Atlantic’s Alexis Madrigal.
