This episode features Dr. Samantha Muka, whose enthusiasm for her work is pretty much guaranteed to improve your day. Sam’s first book is Oceans Under Glass: Tank Craft and the Sciences of the Sea, in which she investigates how a community of aquarium users have created and shared knowledge about how to take care of marine life in captivity. Sam is an assistant professor at the Stevens Institute of Technology, and she is also the author of numerous articles and book chapters about the history of marine science, including essays in Slate and The Atlantic. We talked about how her enthusiasm translates into her writing voice, keeping track of non-traditional sources, and what Sam has in common with a horse (you’ll just have to listen to know what that’s about).
