Nullius in Verba
Smriti Mehta and Daniël Lakens
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.
We draw inspiration from the book Novum Organum, written in 1620 by Francis Bacon, which laid the foundations of the modern scientific method. 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, which have been smashed by Iberian sailors to open a new world for exploration. Just as this marks the exit from the well-charted waters of the Mediterranean into the Atlantic Ocean, Bacon hoped that empirical investigation will similarly smash the old scientific ideas and lead to a greater understanding of the natural world.
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.
