So began an odyssey in sound featuring social calls, echolocation and hunting clicks - and, amazingly, a local Inuit hunting expedition.
About the Podcast Series
The sharpest thinkers talk science - how it shapes our understanding and how we can improve it.
From narwhal song to Bose-Einstein condensates and from pandemics to artificial intelligence - I track down the most interesting science and talk to those behind the research. I want to explore how science shapes our understanding of the universe around us, the challenges we face as we conduct that science and how we might go about improving it.
