Nullius in Verba
Nullius in Verba is a podcast about science—what it is and what it could be. It is hosted by Smriti Mehta from UC Berkeley and Daniël Lakens from Eindhoven University of Technology.
Our logo is an homage to the title page of Novum Organum, which depicts a galleon passing between the mythical Pillars of Hercules on either side of the Strait of Gibraltar. The title of the podcast comes from the motto of the Royal Society, set in typeface Kepler by Robert Slimbach. Our theme song is Newton’s Cradle by Grandbrothers.
